Sexual Health

Primary care physicians frequently offer postexposure prophylaxis for various infections, including influenza, pertussis, tetanus, hepatitis, and Lyme disease, among others. However, the scope of postexposure prophylaxis in primary care is expanding, presenting an opportunity to further integrate it into patient care. As primary care providers, we have the unique advantage of being involved in both preventive care and immediate response, particularly in urgent care or triage scenarios. This dual role is crucial, as timely administration of postexposure prophylaxis can prevent infections from taking hold, especially following high-risk exposures.

Recently, the use of doxycycline as a form of postexposure prophylaxis for sexually transmitted infections (STIs) has gained attention. Traditionally, doxycycline has been used as preexposure or postexposure prophylaxis for conditions like malaria and Lyme disease but has not been widely employed for STI prevention until now. Doxycycline is a relatively common medication, generally safe with side effects that typically resolve upon discontinuation. Several open-label studies have shown that taking 200 mg of doxycycline within 72 hours of condomless sex significantly reduces the incidence of chlamydia, gonorrhea, and syphilis among gay, bisexual, and other men who have sex with men, as well as transgender women who have previously had a bacterial STI. However, these benefits have not been consistently observed among cisgender women and heterosexual men.

Given these findings, the Centers for Disease Control and Prevention now recommends that clinicians discuss the risks and benefits of doxycycline PEP (Doxy PEP) with gay, bisexual, and other men who have sex with men, as well as transgender women who have had a bacterial STI in the past 12 months. This discussion should be part of a shared decision-making process, advising the use of 200 mg of doxycycline within 72 hours of oral, vaginal, or anal sex, with the recommendation not to exceed 200 mg every 24 hours and to reassess the need for continued use every 3-6 months. Doxy PEP can be safely prescribed with preexposure prophylaxis for HIV (PrEP). Patients who receive PrEP may often be eligible for Doxy PEP, though the groups are not always the same.

The shared decision-making process is essential when considering Doxy PEP. While cost-effective and proven to reduce the risk of gonorrhea, chlamydia, and syphilis, its benefits vary among different populations. Moreover, some patients may experience side effects such as photosensitivity and gastrointestinal discomfort. Since the effectiveness of prophylaxis is closely tied to the timing of exposure and the patient’s current risk factors, it is important to regularly evaluate whether Doxy PEP remains beneficial. As there is not yet clear benefit to heterosexual men and cisgender women, opportunities still need to be explored for them.

Integrating Doxy PEP into a primary care practice can be done efficiently. A standing order protocol could be established for telehealth visits or nurse triage, allowing timely administration when patients report an exposure within 72 hours. It could also be incorporated into electronic medical records as part of a smart set for easy access to orders and as standard educational material in after-visit instructions. As this option is new, it is also important to discuss it with patients before they may need it so that they are aware should the need arise. While concerns about antibiotic resistance are valid, studies have not yet shown significant resistance issues related to Doxy PEP use, though ongoing monitoring is necessary.

You might wonder why primary care should prioritize this intervention. As the first point of contact, primary care providers are well-positioned to identify the need for prophylaxis, particularly since its effectiveness diminishes over time. Furthermore, the established, trusting relationships that primary care physicians often have with their patients create a nonjudgmental environment that encourages disclosure of potential exposures. This trust, combined with easier access to care, can make a significant difference in the timely provision of postexposure prophylaxis. By offering comprehensive, holistic care, including prophylaxis, primary care physicians can prevent infections and address conditions before they lead to serious complications. Therefore, family medicine physicians should consider incorporating Doxy PEP into their practices as a standard of care.

TOPLINE:

Long-term exposure to particulate matter < 2.5 μm in diameter (PM_2.5) is linked to a higher risk for infertility in men. Exposure to road traffic noise is associated with a higher risk for infertility in women aged > 35 years and possibly in men aged > 37 years.

METHODOLOGY:

• This nationwide prospective cohort study evaluated the association between long-term exposure to road traffic noise and PM_2.5 and infertility in 526,056 men (mean age, 33.6 years) and 377,850 women (mean age, 32.7 years) who were cohabiting or married, had fewer than two children, and lived in Denmark between 2000 and 2017.
• Residential exposure to road traffic noise (most exposed facade of the home) and PM_2.5 was estimated using validated models and linked to data from national registers.
• Diagnoses of infertility were identified in men and women from the Danish National Patient Register over a mean follow-up of 4.3 years and 4.2 years, respectively.

TAKEAWAY:

• Each 2.9 µg/m³ increase in the 5-year average exposure to PM_2.5 was associated with a 24% increase in the risk for infertility in men aged 30-45 years (adjusted hazard ratio [aHR], 1.24).
• No significant association was found between exposure to PM_2.5 and infertility in women.
• Each 10.2 dB increase in the 5-year average exposure to road traffic noise was associated with a 14% increase in infertility (aHR, 1.14; 95% CI, 1.10-1.18) in women aged 35-45 years.
• Exposure to noise was associated with a reduced risk for infertility in men aged 30.0-36.9 years (aHR, 0.93; 95% CI, 0.91-0.96) and an increased risk in those aged 37-45 years (aHR, 1.06; 95% CI, 1.02-1.11).

IN PRACTICE:

“As many Western countries are facing declining birth rates and increasing maternal age at the birth of a first child, knowledge on environmental pollutants affecting fertility is crucial,” the authors of the study wrote. “It suggests that political implementation of air pollution and noise mitigations may be important tools for improving birth rates in the Western world,” they added.

SOURCE:

The study, led by Mette Sorensen, of the Danish Cancer Institute in Copenhagen, Denmark, was published online in The BMJ.

LIMITATIONS:

The study’s reliance on register data meant information on lifestyle factors such as alcohol use, body mass index, and smoking was unavailable. The lack of data on exposure to noise and PM_2.5 at work and during leisure activities may affect the size and statistical precision of risk estimates.

DISCLOSURES:

The study did not receive any external funding. The authors declared no relevant conflicts of interest.

TOPLINE:

The use of menopausal hormone therapy (MHT) increases breast cancer risk in women with a strong family history of breast cancer. These women have a striking cumulative risk of developing breast cancer (age, 50-80 years) of 22.4%, according to a new modelling study of UK women.

METHODOLOGY:

This was a modeling study integrating two data-sets of UK women: the BOADICEA dataset of age-specific breast cancer risk with family history and the Collaborative Group on Hormonal Factors in Breast Cancer, which covers relative risk for breast cancer with different types and durations of MHT.

Four different breast cancer family history profiles were:

• “Average” family history of breast cancer has unknown affected family members;
• “Modest” family history comprises a single first-degree relative with breast cancer at the age of 60 years.
• “Intermediate” family history comprises a single first-degree relative who developed breast cancer at the age of 40 years.
• “Strong” family history comprises two first-degree relatives who developed breast cancer at the age of 50 years.

TAKEAWAY:

• The lowest risk category: “Average” family history with no MHT use has a cumulative breast cancer risk (age, 50-80 years) of 9.8% and a risk of dying from breast cancer of 1.7%. These risks rise with 5 years’ exposure to MHT (age, 50-55 years) to 11.0% and 1.8%, respectively.
• The highest risk category: “Strong” family history with no MHT use has a cumulative breast cancer risk (age, 50-80 years) of 19.6% and a risk of dying from breast cancer of 3.2%. These risks rise with 5 years’ exposure to MHT (age, 50-55 years) to 22.4% and 3.5%, respectively.

IN PRACTICE:

The authors concluded that, “These integrated data will enable more accurate estimates of absolute and attributable risk associated with MHT exposure for women with a family history of breast cancer, informing shared decision-making.”

Childhood cancers represent a diverse group of neoplasms, and thanks to advances in treatment, survival rates have improved significantly. Today, more than 80%-85% of children diagnosed with cancer in developed countries survive into adulthood.

This increase in survival has brought new challenges, however. Compared with the general population, childhood cancer survivors (CCS) are at a notably higher risk for early mortality, developing secondary cancers, and experiencing various long-term clinical and psychosocial issues stemming from their disease or its treatment.

Long-term follow-up care for CCS is a complex and evolving field. Despite ongoing efforts to establish global and national guidelines, current evidence indicates that the care and management of these patients remain suboptimal.

Sexual dysfunction is a common and significant late effect among CCS. The disruptions caused by cancer and its treatment can interfere with normal physiological and psychological development, leading to issues with sexual function. This aspect of health is critical as it influences not just physical well-being but also psychosocial, developmental, and emotional health.
 

Characteristics and Mechanisms

Sexual functioning encompasses the physiological and psychological aspects of sexual behavior, including desire, arousal, orgasm, sexual pleasure, and overall satisfaction.

As CCS reach adolescence or adulthood, they often face sexual and reproductive issues, particularly as they enter romantic relationships.

Sexual functioning is a complex process that relies on the interaction of various factors, including physiological health, psychosexual development, romantic relationships, body image, and desire.

Despite its importance, the impact of childhood cancer on sexual function is often overlooked, even though cancer and its treatments can have lifelong effects. 
 

Sexual Function in CCS

A recent review aimed to summarize the existing research on sexual function among CCS, highlighting assessment tools, key stages of psychosexual development, common sexual problems, and the prevalence of sexual dysfunction.

The review study included 22 studies published between 2000 and 2022, comprising two qualitative, six cohort, and 14 cross-sectional studies.

Most CCS reached all key stages of psychosexual development at an average age of 29.8 years. Although some milestones were achieved later than is typical, many survivors felt they reached these stages at the appropriate time. Sexual initiation was less common among those who had undergone intensive neurotoxic treatments, such as those diagnosed with brain tumors or leukemia in childhood.

In a cross-sectional study of CCS aged 17-39 years, about one third had never engaged in sexual intercourse, 41.4% reported never experiencing sexual attraction, 44.8% were dissatisfied with their sex lives, and many rarely felt sexually attractive to others. Another study found that common issues among CCS included a lack of interest in sex (30%), difficulty enjoying sex (24%), and difficulty becoming aroused (23%). However, comparing and analyzing these problems was challenging due to the lack of standardized assessment criteria.

The prevalence of sexual dysfunction among CCS ranged from 12.3% to 46.5%. For males, the prevalence ranged from 12.3% to 54.0%, while for females, it ranged from 19.9% to 57.0%.
 

Factors Influencing Sexual Function

The review identified the following four categories of factors influencing sexual function in CCS: Demographic, treatment-related, psychological, and physiological.

Demographic factors: Gender, age, education level, relationship status, income level, and race all play roles in sexual function.

Female survivors reported more severe sexual dysfunction and poorer sexual health than did male survivors. Age at cancer diagnosis, age at evaluation, and the time since diagnosis were closely linked to sexual experiences. Patients diagnosed with cancer during childhood tended to report better sexual function than those diagnosed during adolescence.

Treatment-related factors: The type of cancer and intensity of treatment, along with surgical history, were significant factors. Surgeries involving the spinal cord or sympathetic nerves, as well as a history of prostate or pelvic surgery, were strongly associated with erectile dysfunction in men. In women, pelvic surgeries and treatments to the pelvic area were commonly linked to sexual dysfunction.

The association between treatment intensity and sexual function was noted across several studies, although the results were not always consistent. For example, testicular radiation above 10 Gy was positively correlated with sexual dysfunction. Women who underwent more intensive treatments were more likely to report issues in multiple areas of sexual function, while men in this group were less likely to have children.

Among female CCS, certain types of cancer, such as germ cell tumors, renal tumors, and leukemia, present a higher risk for sexual dysfunction. Women who had CNS tumors in childhood frequently reported problems like difficulty in sexual arousal, low sexual satisfaction, infrequent sexual activity, and fewer sexual partners, compared with survivors of other cancers. Survivors of acute lymphoblastic leukemia and those who underwent hematopoietic stem cell transplantation (HSCT) also showed varying degrees of impaired sexual function, compared with the general population. The HSCT group showed significant testicular damage, including reduced testicular volumes, low testosterone levels, and low sperm counts.

Psychological factors: These factors, such as emotional distress, play a significant role in sexual dysfunction among CCS. Symptoms like anxiety, nervousness during sexual activity, and depression are commonly reported by those with sexual dysfunction. The connection between body image and sexual function is complex. Many CCS with sexual dysfunction express concern about how others, particularly their partners, perceived their altered body image due to cancer and its treatment.

Physiological factors: In male CCS, low serum testosterone levels and low lean muscle mass are linked to an increased risk for sexual dysfunction. Treatments involving alkylating agents or testicular radiation, and surgery or radiotherapy targeting the genitourinary organs or the hypothalamic-pituitary region, can lead to various physiological and endocrine disorders, contributing to sexual dysfunction. Despite these risks, there is a lack of research evaluating sexual function through the lens of the hypothalamic-pituitary-gonadal axis and neuroendocrine pathways.

Childhood cancers represent a diverse group of neoplasms, and thanks to advances in treatment, survival rates have improved significantly. Today, more than 80%-85% of children diagnosed with cancer in developed countries survive into adulthood.

This increase in survival has brought new challenges, however. Compared with the general population, childhood cancer survivors (CCS) are at a notably higher risk for early mortality, developing secondary cancers, and experiencing various long-term clinical and psychosocial issues stemming from their disease or its treatment.

Long-term follow-up care for CCS is a complex and evolving field. Despite ongoing efforts to establish global and national guidelines, current evidence indicates that the care and management of these patients remain suboptimal.

Sexual dysfunction is a common and significant late effect among CCS. The disruptions caused by cancer and its treatment can interfere with normal physiological and psychological development, leading to issues with sexual function. This aspect of health is critical as it influences not just physical well-being but also psychosocial, developmental, and emotional health.
 

Characteristics and Mechanisms

Sexual functioning encompasses the physiological and psychological aspects of sexual behavior, including desire, arousal, orgasm, sexual pleasure, and overall satisfaction.

As CCS reach adolescence or adulthood, they often face sexual and reproductive issues, particularly as they enter romantic relationships.

Sexual functioning is a complex process that relies on the interaction of various factors, including physiological health, psychosexual development, romantic relationships, body image, and desire.

Despite its importance, the impact of childhood cancer on sexual function is often overlooked, even though cancer and its treatments can have lifelong effects. 
 

Sexual Function in CCS

A recent review aimed to summarize the existing research on sexual function among CCS, highlighting assessment tools, key stages of psychosexual development, common sexual problems, and the prevalence of sexual dysfunction.

The review study included 22 studies published between 2000 and 2022, comprising two qualitative, six cohort, and 14 cross-sectional studies.

Most CCS reached all key stages of psychosexual development at an average age of 29.8 years. Although some milestones were achieved later than is typical, many survivors felt they reached these stages at the appropriate time. Sexual initiation was less common among those who had undergone intensive neurotoxic treatments, such as those diagnosed with brain tumors or leukemia in childhood.

In a cross-sectional study of CCS aged 17-39 years, about one third had never engaged in sexual intercourse, 41.4% reported never experiencing sexual attraction, 44.8% were dissatisfied with their sex lives, and many rarely felt sexually attractive to others. Another study found that common issues among CCS included a lack of interest in sex (30%), difficulty enjoying sex (24%), and difficulty becoming aroused (23%). However, comparing and analyzing these problems was challenging due to the lack of standardized assessment criteria.

The prevalence of sexual dysfunction among CCS ranged from 12.3% to 46.5%. For males, the prevalence ranged from 12.3% to 54.0%, while for females, it ranged from 19.9% to 57.0%.
 

Factors Influencing Sexual Function

The review identified the following four categories of factors influencing sexual function in CCS: Demographic, treatment-related, psychological, and physiological.

Demographic factors: Gender, age, education level, relationship status, income level, and race all play roles in sexual function.

Female survivors reported more severe sexual dysfunction and poorer sexual health than did male survivors. Age at cancer diagnosis, age at evaluation, and the time since diagnosis were closely linked to sexual experiences. Patients diagnosed with cancer during childhood tended to report better sexual function than those diagnosed during adolescence.

Treatment-related factors: The type of cancer and intensity of treatment, along with surgical history, were significant factors. Surgeries involving the spinal cord or sympathetic nerves, as well as a history of prostate or pelvic surgery, were strongly associated with erectile dysfunction in men. In women, pelvic surgeries and treatments to the pelvic area were commonly linked to sexual dysfunction.

Preexposure prophylaxis prescription reversals and abandonments were lower for patients seen by primary care clinicians than by other non–infectious disease clinicians, based on data from approximately 37,000 individuals.

Although preexposure prophylaxis (PrEP) has been associated with a reduced risk of HIV (human immunodeficiency virus) infection when used as prescribed, the association between PrEP prescription pickup and specialty of the prescribing clinician has not been examined, wrote Lorraine T. Dean, ScD, an epidemiologist at Johns Hopkins University, Baltimore, Maryland, and colleagues.

“HIV PrEP is highly effective at preventing new HIV cases, and while use is on the rise, is still used much less than it should be by people who are at risk of HIV,” Dr. Dean said in an interview. “This study is helpful in pinpointing who is at risk for not picking up PrEP and in helping us think through how to reach them so that they can be better positioned to get PrEP,” she said.

In a study published in JAMA Internal Medicine, the researchers reviewed data for PrEP care. The study population included 37,003 patients aged 18 years and older who received new insurer-approved PrEP prescriptions between 2015 and 2019. Most of the patients (77%) ranged in age from 25 to 64 years; 88% were male.

Pharmacy claims data were matched with clinician data from the US National Plan and Provider Enumeration System.

Clinicians were divided into three groups: primary care providers (PCPs), infectious disease specialists (IDs), and other specialists (defined as any clinician prescribing PrEP but not classified as a PCP or an ID specialist). The main binary outcomes were prescription reversal (defined as when a patient failed to retrieve a prescription) and abandonment (defined as when a patient neglected to pick up a prescription for 1 year).

Overall, of 24,604 patients 67% received prescriptions from PCPs, 3,571 (10%) received prescriptions from ID specialists, and 8828 (24%) received prescriptions from other specialty clinicians.

The prevalence of reversals for patients seen by PCPs, ID specialists, and other specialty clinicians was 18%, 18%, and 25%, respectively. The prevalence of abandonments by clinician group was 12%, 12%, and 20%, respectively.

In a regression analysis, patients prescribed PrEP by ID specialists had 10% lower odds of reversals and 12% lower odds of abandonments compared to those seen by PCPs (odds ratio 0.90 and 0.88, respectively). However, patients seen by other clinicians (not primary care or ID) were 33% and 54% more likely to have reversals and abandonments, respectively, compared with those seen by PCPs.

Many patients at risk for HIV first see a PCP and then are referred to a specialist, such as an ID physician, Dr. Dean said. “The patients who take the time to then follow up with a specialist may be most motivated and able to follow through with the specialist’s request, in this case, accessing their PrEP prescription,” she said. In the current study, the researchers were most surprised by how many other specialty providers are involved in PrEP care, which is very positive given the effectiveness of the medication, she noted.

“Our results suggest that a wide range of prescribers, regardless of specialty, should be equipped to prescribe PrEP as well as offer PrEP counseling,” Dr. Dean said. A key takeaway for clinicians is that PrEP should have no cost for the majority of patients in the United States, she emphasized. The absence of cost expands the population who should be interested and able to access PrEP, she said. Therefore, providers should be prepared to recommend PrEP to eligible patients, and seek training or continuing medical education for themselves so they feel equipped to prescribe and counsel patients on PrEP, she said.

“One limitation of this work is that, while it can point to what is happening, it cannot tell us why the reversals are happening; what is the reason patients prescribed by certain providers are more or less likely to get their PrEP,” Dr. Dean explained. “We have tried to do interviews with patients to understand why this might be happening, but it’s hard to find people who aren’t showing up to do something, compared to finding people who are showing up to do something,” she said. Alternatively, researchers could interview providers to understand their perspective on why differences in prescription pickups occur across specialties, she said.

Looking ahead, “a national PrEP program that includes elements of required clinician training could be beneficial, and research on how a national PrEP program could be implemented and impact HIV rates would be helpful in considering this strategy of prevention,” said Dr. Dean. 
 

Support All Prescribers to Increase PrEP Adherence

Differences in uptake of PrEP prescriptions may be explained by the different populations seen by various specialties, Meredith Green, MD, of Indiana University School of Medicine, Indianapolis, and Lona Mody, MD, of the University of Michigan, Ann Arbor, wrote in an accompanying editorial. However, the key question is how to support all prescribers and promote initiation and adherence to PrEP, they said.

Considerations include whether people at risk for HIV prefer to discuss PrEP with a clinician they already know, vs. a new specialist, but many PCPs are not familiar with the latest PrEP guidelines, they said.

“Interventions that support PrEP provision by PCPs, especially since they prescribed the largest proportion of PrEP prescriptions, can accelerate the uptake of PrEP,” the editorialists wrote.

“Supporting a diverse clinician workforce reflective of communities most impacted by HIV will remain critical, as will acknowledging and addressing HIV stigma,” they said. Educational interventions, including online programs and specialist access for complex cases, would help as well, they said. The approval of additional PrEP agents since the current study was conducted make it even more important to support PrEP prescribers and promote treatment adherence for those at risk for HIV, Dr. Green and Dr. Mody emphasized.

The study was funded by the National Institutes of Health. Dr. Dean had no financial conflicts to disclose. Dr. Green disclosed grants from Gilead and royalties from Wolters Kluwer unrelated to the current study; she also disclosed serving on the Centers for Disease Control and Prevention/Health Resources and Services Administration advisory committee on HIV, viral hepatitis, and sexually transmitted infection prevention and treatment. Dr. Mody disclosed grants from the US National Institute on Aging, Veterans Affairs, Centers for Disease Control and Prevention, NanoVibronix, and UpToDate unrelated to the current study.

I would like to briefly discuss what I consider to be a very discouraging report and one that I believe we as an oncology society and, quite frankly, as a medical community need to deal with. 

The manuscript I’m referring to is from the United States Department of Health and Human Services, titled, “Human Papillomavirus Vaccination Coverage in Children Ages 9-17 Years: United States, 2022.” This particular analysis looked at the coverage of both men and women — young boys and young girls, I would say — receiving at least one dose of the recommended human papillomavirus (HPV) vaccination. 

Since 2006, girls have been recommended to receive HPV vaccination; for boys, it’s been since 2011. Certainly, the time period that we’re considering falls within the recommendations based on overwhelmingly positive data. Now, today, still, the recommendation is for more than one vaccine. Obviously, there may be evidence in the future that a single vaccination may be acceptable or appropriate. But today, it’s more than one. 

In this particular analysis, they were looking at just a single vaccination. The vaccines have targeted young individuals, both male and female children aged 11-12 years, but it’s certainly acceptable to look starting at age 9. 

What is the bottom line? At least one dose of the HPV vaccination was given to 38.6% of children aged 9-17 years in 2022. We are talking about a cancer-preventive vaccine, which on the basis of population-based data in the United States, but also in other countries, is incredibly effective in preventing HPV-associated cancers. This not only includes cervical cancer, but also a large percentage of head and neck cancers.

For this vaccine, which is incredibly safe and incredibly effective, in this country, only 38.6% have received even a single dose. It is noted that the individuals with private insurance had a higher rate, at 41.5%, than individuals with no insurance, at only 20.7%. 

In my opinion, this is clearly a failure of our public health establishment at all levels. My own focus has been in gynecologic cancers. I’ve seen young women with advanced cervical cancer, and this is a disease we can prevent. Yet, this is where we are. 

For those of you who are interested in cancer prevention or public health, I think this is a very sobering statistic. It’s my plea and my hope that we can, as a society, somehow do something about it. 

I thank you for listening. I would encourage you to think about this question if you’re in this area.

I would like to briefly discuss what I consider to be a very discouraging report and one that I believe we as an oncology society and, quite frankly, as a medical community need to deal with. 

The manuscript I’m referring to is from the United States Department of Health and Human Services, titled, “Human Papillomavirus Vaccination Coverage in Children Ages 9-17 Years: United States, 2022.” This particular analysis looked at the coverage of both men and women — young boys and young girls, I would say — receiving at least one dose of the recommended human papillomavirus (HPV) vaccination. 

Since 2006, girls have been recommended to receive HPV vaccination; for boys, it’s been since 2011. Certainly, the time period that we’re considering falls within the recommendations based on overwhelmingly positive data. Now, today, still, the recommendation is for more than one vaccine. Obviously, there may be evidence in the future that a single vaccination may be acceptable or appropriate. But today, it’s more than one. 

In this particular analysis, they were looking at just a single vaccination. The vaccines have targeted young individuals, both male and female children aged 11-12 years, but it’s certainly acceptable to look starting at age 9. 

What is the bottom line? At least one dose of the HPV vaccination was given to 38.6% of children aged 9-17 years in 2022. We are talking about a cancer-preventive vaccine, which on the basis of population-based data in the United States, but also in other countries, is incredibly effective in preventing HPV-associated cancers. This not only includes cervical cancer, but also a large percentage of head and neck cancers.

For this vaccine, which is incredibly safe and incredibly effective, in this country, only 38.6% have received even a single dose. It is noted that the individuals with private insurance had a higher rate, at 41.5%, than individuals with no insurance, at only 20.7%. 

In my opinion, this is clearly a failure of our public health establishment at all levels. My own focus has been in gynecologic cancers. I’ve seen young women with advanced cervical cancer, and this is a disease we can prevent. Yet, this is where we are. 

For those of you who are interested in cancer prevention or public health, I think this is a very sobering statistic. It’s my plea and my hope that we can, as a society, somehow do something about it. 

I thank you for listening. I would encourage you to think about this question if you’re in this area.

Women in the perimenopausal period who live in rural areas have a higher prevalence of symptoms typical of this period and a poorer health-related quality of life than women living in urban areas, according to a cross-sectional study that was conducted in Spain.

Cristina Llaneza Suárez, a specialist in family and community medicine and the lead author of the study, told this news organization that women living in rural areas face greater difficulties with access to healthcare services, employment, and transportation and a heavier burden of caregiving. She mentioned that these barriers “can represent an added challenge during the perimenopausal stage, when significant life changes generally occur for all women.” The challenges may lead to “poorer health-related quality of life during perimenopause, compared with women living in urban areas.”

The research group led by Dr. Llaneza aimed to test the hypothesis that sociodemographic characteristics influence symptoms and quality of life in women in perimenopause. They enrolled 270 women aged 45-55 years from eight autonomous communities in Spain who had variability in their menstrual cycles (lasting more than 7 days or amenorrhea greater than 60 days but less than a year).

This cross-sectional study was conducted from December 2019 to April 2023, using the short version of the Cervantes scale to assess health-related quality of life and the Beck Depression Inventory to evaluate associated depressive symptoms.

Among the main findings of the study was that sociocultural factors can influence the perception of perimenopausal symptoms. Living in rural areas has a negative effect on health-related quality of life scales, and this finding is consistent with those of previous studies conducted on women in India, Turkey, Poland, and Peru.

In addition, the selected sample of women experiencing changes in their menstrual cycles and residing in rural areas showed a high prevalence of hot flashes (70% overall and 80% in rural areas) and a poorer quality of life in women with obesity.

“It is striking that, although there is a worse perception of quality of life during perimenopause in women living in rural areas, the proportion of women experiencing some degree of depressive symptoms, according to the Beck inventory, was similar to that of women residing in urban areas,” said Dr. Llaneza. She noted that “no worse scores were observed in sexuality or in the couple relationship.”
 

Rural Physicians’ Role

Women in the perimenopausal period face significant challenges resulting from inadequate access to healthcare services and limited awareness about menopause. In many countries, this topic is still taboo, both in the family environment and in workplaces and health centers.

Dr. Llaneza mentioned that when she began her training as a primary care physician in a rural population, she witnessed firsthand some of the barriers that women in this age group face, such as limited access to healthcare due to a lack of public transportation. She added that, coupled with this challenge, “there are no regular public transport services that allow independent access for patients, and many [women] lack a driver’s license, making them dependent on others to receive healthcare.” Another important point that she identified was the lack of health education in rural populations, which leads to a minimization of perimenopausal symptoms and causes delays in prevention and early detection.

According to the World Health Organization, healthcare professionals often lack the necessary training to recognize and treat the symptoms of perimenopause and postmenopause. This situation, coupled with the limited attention given to the sexual well-being of menopausal women, contributes to gynecological problems and risks for sexually transmitted infections in this population. The absence of specific health policies and funding for menopause exacerbates the situation, particularly in regions where other health needs compete for limited resources.

Dr. Llaneza noted that primary care physicians in rural areas are responsible for leading primary prevention actions through community interventions that contribute to improving health. Community physicians in rural areas have a lower patient load than urban physicians do. Therefore, “this allows for a more thorough management and closer monitoring of these conditions, which highlights the importance of prevention of perimenopausal symptoms and community education,” she said.

An important goal in improving the quality of life of women in the perimenopausal period is reducing symptoms. Hormone replacement therapy is the cornerstone of treatment, along with nonhormonal therapies such as the use of isoflavones. However, the aforementioned barriers lead to a delay in initiating effective treatment.

Dr. Llaneza added that the main limitation that she encountered during her clinical practice in rural areas regarding the initiation of hormonal therapy was “the reluctance of certain professionals to start it, as they consider that these drugs should be prescribed by menopause specialists because of potential side effects and the increased risk for developing breast cancer.”
 

Call for Training

Dr. Llaneza and her research team emphasized the need for further research on new drugs for controlling vasomotor symptoms, expressing their interest in conducting additional studies. “We would like to conduct a study on the use of these therapies in perimenopausal and postmenopausal women residing in rural areas.

“We believe that our data may be of interest to healthcare authorities seeking to combat population exodus in rural areas,” they wrote. In addition, they recommended additional training for rural primary care physicians on perimenopause and menopause topics regarding prevention, management, and access, as well as further awareness about preventing depressive symptoms in this population.

Dr. Llaneza declared that she has no relevant financial relationships.

Twice-yearly injections are 100% effective in preventing new infections, according to the final results from the PURPOSE 1 trial of lenacapavir.

For weeks, the HIV community has been talking about this highly anticipated clinical trial and whether the strong — and to many, surprising — interim results would hold at final presentation at the International AIDS Conference 2024 in Munich, Germany.

Presenting the results, Linda-Gail Bekker, MD, director of the Desmond Tutu HIV Center at the University of Cape Town, South Africa, reported zero new infections in those who got the shots in the study of about 5000 young women. In the group given daily oral preexposure prophylaxis (PrEP), roughly 2% contracted HIV from infected partners.

“A twice-yearly PrEP choice could overcome some of the adherence and persistence challenges and contribute critically to our quest to reduce HIV infection in women around the world,” Dr. Bekker said about the results, which were published simultaneously in The New England Journal of Medicine.

PURPOSE 1 confirmed that lenacapavir is a “breakthrough” for HIV prevention, said International AIDS Society president Sharon Lewin, PhD, MBBS. It has “huge public health potential,” said Dr. Lewin, the AIDS 2024 conference cochair and director of the Peter Doherty Institute for Infection and Immunity at the University of Melbourne in Australia.

Lenacapavir is a novel, first-in-class multistage HIV-1 capsid inhibitor with a long half-life, which enables the twice-yearly dosing.

PURPOSE 1 enrolled women aged 15-25 years who were at risk for HIV in South Africa and Uganda, with a primary endpoint of HIV infection. Because of the previously announced interim results, which showed the injection was preventing infections, study sponsor Gilead Sciences discontinued the randomized phase of the trial and shifted to an open-label design for lenacapavir.

“One hundred percent efficacy is more that we could ever have hoped for a potential prevention efficacy,” said Christoph Spinner, MD, MBA, an infectious disease specialist at the University Hospital of the Technical University of Munich and AIDS 2024 conference cochair.

Dr. Spinner added that while this is the first study of lenacapavir for PrEP, it’s also the first to explore outcomes of emtricitabine-tenofovir in cisgender women.
 

Strong Adherence Rates

The twice-yearly injection demonstrated adherence rates above 90% in the trial for both the 6- and 12-month injection intervals.

“Adherence was 91.5% at week 26 and 92.8% at week 52,” Dr. Bekker reported. 

The trial compared three PrEP options including the lenacapavir injection to once-daily oral emtricitabine 200 mg and tenofovir-alafenamide 25 mg (F/TAF) and once-daily emtricitabine 200 mg and tenofovir–disoproxil fumarate 300 mg (F/TDF).

“Most participants in both the F/TAF and F/TDF groups had low adherence, and this declined over time,” Dr. Bekker reported. At 52 weeks, the vast majority of patients on both oral therapies had low adherence with dosing, defined at less than two doses a week.

Dr. Bekker called the adherence to the oral agents in this trial “disappointing.”

Findings from the trial underscore the challenges of adherence to a daily oral medication, Rochelle Walensky, MD, and Lindsey Baden, MD, from the Harvard Kennedy School of Government and Harvard Business School in Cambridge, Massachusetts, wrote in an editorial accompanying the published results.

With almost 92% attendance for the twice-yearly lenacapavir injections, the “well-done,” large, randomized, controlled trial “exemplifies not only that women can dependably adhere to this administration schedule, but also that levels of an HIV-1 capsid inhibitor can remain high enough over a period of 6 months to reliably prevent infection,” they added. 

Another key focus of the presentation was adverse events. The rate of adverse events grade 3 or more in the lenacapavir arm was 4.1%, Bekker said, which is slightly lower than the rates in the oral arms. The rates of serious adverse events were 2.8% for lenacapavir, 4% for F/TAF and 3.3% for F/TDF. 
 

Injection Site Reactions

Injection site reactions occurred in 68% of the lenacapavir group, including 63% with subcutaneous nodules.

The injection can form “a drug depot which may be palpable as a nodule,” Dr. Bekker said. In the placebo group, 34% of patients had injection-site reactions and 16% had nodules. Nearly all injection-site reactions were grade 1 or 2, she said. “Higher grade injection-site reactions were rare and not serious and occurred in a similar percentage in lenacapavir and placebo,” she said.

Overall, more than 25,000 injections of lenacapavir have been given, Dr. Bekker said, and four patients discontinued treatment because of injection-site reactions. “Reporting of injection-site reactions, including nodules, decreased with subsequent doses,” she said.

Contraception was not a requirement for enrollment in the study, Dr. Bekker pointed out, and pregnancy outcomes across the treatment arms were similar to the general population.
 

First in a Series of Trials

This is the first in a series of PURPOSE trials, Bekker reported. The phase 3 PURPOSE 2 trial, enrolling 3000 gay men, transgender women, transgender men and gender nonbinary people who have sex with male partners, is the second pivotal trial now underway.

Three other smaller trials are in the clinic in the United States and Europe.

PURPOSE 1 participants will continue to access lenacapavir until the product is available in South Africa and Uganda, Dr. Bekker said. Trial sponsor Gilead Sciences is also developing a direct licensing program to expedite generic access to the drug in high-incidence, resource-limited countries, she said.

Dr. Walensky and Dr. Baden report that lenacapavir currently costs about $43,000 annually in the United States. “But the results of the PURPOSE 1 trial have now created a moral imperative to make lenacapavir broadly accessible and affordable as PrEP” to people who were enrolled, as well as all those who are similarly eligible and could benefit.

So now we have a PrEP product with high efficacy, they added. “That is great news for science but not (yet) great for women.” 

Given the high pregnancy rate among participants in the PURPOSE 1 trial, Dr. Walensky and Dr. Baden point out the assessment of lenacapavir safety is a priority. They are also interested in learning more about drug resistance with this new option. 

“I f approved and delivered — rapidly, affordably, and equitably — to those who need or want it, this long-acting tool could help accelerate global progress in HIV prevention,” Dr. Lewin said.

Now, she added, “we eagerly await results from PURPOSE 2.”

Given the high pregnancy rate among participants in the PURPOSE 1 trial, Dr. Walensky and Dr. Baden point out the assessment of lenacapavir safety is a priority. They are also interested in learning more about drug resistance with this new option. 

“I f approved and delivered — rapidly, affordably, and equitably — to those who need or want it, this long-acting tool could help accelerate global progress in HIV prevention,” Dr. Lewin said.

Now, she added, “we eagerly await results from PURPOSE 2.”

Twice-yearly injections are 100% effective in preventing new infections, according to the final results from the PURPOSE 1 trial of lenacapavir.

For weeks, the HIV community has been talking about this highly anticipated clinical trial and whether the strong — and to many, surprising — interim results would hold at final presentation at the International AIDS Conference 2024 in Munich, Germany.

Presenting the results, Linda-Gail Bekker, MD, director of the Desmond Tutu HIV Center at the University of Cape Town, South Africa, reported zero new infections in those who got the shots in the study of about 5000 young women. In the group given daily oral preexposure prophylaxis (PrEP), roughly 2% contracted HIV from infected partners.

“A twice-yearly PrEP choice could overcome some of the adherence and persistence challenges and contribute critically to our quest to reduce HIV infection in women around the world,” Dr. Bekker said about the results, which were published simultaneously in The New England Journal of Medicine.

PURPOSE 1 confirmed that lenacapavir is a “breakthrough” for HIV prevention, said International AIDS Society president Sharon Lewin, PhD, MBBS. It has “huge public health potential,” said Dr. Lewin, the AIDS 2024 conference cochair and director of the Peter Doherty Institute for Infection and Immunity at the University of Melbourne in Australia.

Lenacapavir is a novel, first-in-class multistage HIV-1 capsid inhibitor with a long half-life, which enables the twice-yearly dosing.

PURPOSE 1 enrolled women aged 15-25 years who were at risk for HIV in South Africa and Uganda, with a primary endpoint of HIV infection. Because of the previously announced interim results, which showed the injection was preventing infections, study sponsor Gilead Sciences discontinued the randomized phase of the trial and shifted to an open-label design for lenacapavir.

“One hundred percent efficacy is more that we could ever have hoped for a potential prevention efficacy,” said Christoph Spinner, MD, MBA, an infectious disease specialist at the University Hospital of the Technical University of Munich and AIDS 2024 conference cochair.

Dr. Spinner added that while this is the first study of lenacapavir for PrEP, it’s also the first to explore outcomes of emtricitabine-tenofovir in cisgender women.
 

Strong Adherence Rates

The twice-yearly injection demonstrated adherence rates above 90% in the trial for both the 6- and 12-month injection intervals.

“Adherence was 91.5% at week 26 and 92.8% at week 52,” Dr. Bekker reported. 

The trial compared three PrEP options including the lenacapavir injection to once-daily oral emtricitabine 200 mg and tenofovir-alafenamide 25 mg (F/TAF) and once-daily emtricitabine 200 mg and tenofovir–disoproxil fumarate 300 mg (F/TDF).

“Most participants in both the F/TAF and F/TDF groups had low adherence, and this declined over time,” Dr. Bekker reported. At 52 weeks, the vast majority of patients on both oral therapies had low adherence with dosing, defined at less than two doses a week.

Dr. Bekker called the adherence to the oral agents in this trial “disappointing.”

Findings from the trial underscore the challenges of adherence to a daily oral medication, Rochelle Walensky, MD, and Lindsey Baden, MD, from the Harvard Kennedy School of Government and Harvard Business School in Cambridge, Massachusetts, wrote in an editorial accompanying the published results.

With almost 92% attendance for the twice-yearly lenacapavir injections, the “well-done,” large, randomized, controlled trial “exemplifies not only that women can dependably adhere to this administration schedule, but also that levels of an HIV-1 capsid inhibitor can remain high enough over a period of 6 months to reliably prevent infection,” they added. 

Another key focus of the presentation was adverse events. The rate of adverse events grade 3 or more in the lenacapavir arm was 4.1%, Bekker said, which is slightly lower than the rates in the oral arms. The rates of serious adverse events were 2.8% for lenacapavir, 4% for F/TAF and 3.3% for F/TDF. 
 

Injection Site Reactions

Injection site reactions occurred in 68% of the lenacapavir group, including 63% with subcutaneous nodules.

The injection can form “a drug depot which may be palpable as a nodule,” Dr. Bekker said. In the placebo group, 34% of patients had injection-site reactions and 16% had nodules. Nearly all injection-site reactions were grade 1 or 2, she said. “Higher grade injection-site reactions were rare and not serious and occurred in a similar percentage in lenacapavir and placebo,” she said.

Overall, more than 25,000 injections of lenacapavir have been given, Dr. Bekker said, and four patients discontinued treatment because of injection-site reactions. “Reporting of injection-site reactions, including nodules, decreased with subsequent doses,” she said.

Contraception was not a requirement for enrollment in the study, Dr. Bekker pointed out, and pregnancy outcomes across the treatment arms were similar to the general population.
 

First in a Series of Trials

This is the first in a series of PURPOSE trials, Bekker reported. The phase 3 PURPOSE 2 trial, enrolling 3000 gay men, transgender women, transgender men and gender nonbinary people who have sex with male partners, is the second pivotal trial now underway.

Three other smaller trials are in the clinic in the United States and Europe.

PURPOSE 1 participants will continue to access lenacapavir until the product is available in South Africa and Uganda, Dr. Bekker said. Trial sponsor Gilead Sciences is also developing a direct licensing program to expedite generic access to the drug in high-incidence, resource-limited countries, she said.

Dr. Walensky and Dr. Baden report that lenacapavir currently costs about $43,000 annually in the United States. “But the results of the PURPOSE 1 trial have now created a moral imperative to make lenacapavir broadly accessible and affordable as PrEP” to people who were enrolled, as well as all those who are similarly eligible and could benefit.

So now we have a PrEP product with high efficacy, they added. “That is great news for science but not (yet) great for women.” 

Given the high pregnancy rate among participants in the PURPOSE 1 trial, Dr. Walensky and Dr. Baden point out the assessment of lenacapavir safety is a priority. They are also interested in learning more about drug resistance with this new option. 

“I f approved and delivered — rapidly, affordably, and equitably — to those who need or want it, this long-acting tool could help accelerate global progress in HIV prevention,” Dr. Lewin said.

Now, she added, “we eagerly await results from PURPOSE 2.”

Rachel S. Rubin, MD: I have an interesting topic for you — kind of shocking, actually. Some of you may have read a story earlier this year in The New York Times about the alarming rise among young people of choking or strangulation during sex. I spoke recently with Dr. Debby Herbenick about this concerning and violent trend. Dr. Herbenick is a well-known sexuality researcher and professor at the Indiana University School of Public Health. Welcome, Dr. Herbenick. Can you tell us about your research into this new trend?

Debby Herbenick, PhD: This is some of the most important research that I’ve done. I’ve been studying sexual behaviors and trends for about 14 years in terms of nationally representative studies that we do. Over time, we noticed a trend of increasing prevalence of rough sex practices. 

Now, there’s always been a lot of sexual diversity in the world throughout history. But the main trend that we have focused on in recent years that is important for everyone in medicine to know about is this rapid increase — actually, a really big increase — in what people call “sexual choking,” even though it’s a form of strangulation. The increase is mostly seen in teenagers and young adults. 

We’ve done US nationally representative surveys as well as college campus representative surveys. We find that consistently across four campus representative surveys that 64% of women report having ever been choked during sex, and around 1 in 3 women (aged 18-24 years) throughout the whole country report having been choked during their most recent sexual activity with another person. They call it choking, but because it involves usually one hand — sometimes two hands or a forearm or an object, like a belt or a cord to tie around the neck — it is technically strangulation, because it’s external pressure to the neck to reduce or stop airflow or blood flow. 

Dr. Rubin: These numbers are staggering, right? Everyone listening now is taking care of someone who has been strangled as a form of sexual pleasure. What does this mean from a safety perspective? And as doctors who are working these patients up for migraines and other health problems, what is the research showing? 

Dr. Herbenick: We certainly are seeing people report recurrent headaches and ringing in the ears. There are things we’ve just barely scratched the surface on. Those of us working in this space believe that for anybody coming in for an unexplained stroke (for example, under age 50), you might consider some imaging to see if they have a dissection. We are hearing about people who, when you really probe to find out whether they’ve had pressure on the neck, they report that indeed that they have. So, we have to be thinking about neurologic symptoms. We know that they’re experiencing these at a pretty high rate. 

For people who are engaging in these practices, they should know about the health risks, but we find that most don’t. They may have heard that if it’s really intense high pressure, that in rare cases people can die, but most have never heard of anything in between. So, they’re not necessarily connecting their voice hoarseness, or the recurrent headaches or the sensitivity to light they are having, to an experience of being choked. We need to be paying attention to neurologic symptoms. 

Most physicians I speak with at conferences say that where they feel like they can step into this conversation is through anticipatory guidance and letting their patients know that they may have heard about this trend, and a lot of people are talking about the health consequences, and I want to share some information with you — not coming at it from a place of shame or judgment, but providing some information so that [patients] actually get some medical facts about this that could be lifesaving. 

Dr. Rubin: I see such a big gap in my medical training. I was taught to say, “Hey, do you smoke, do you drink, do you do drugs? Do you have sex? Men, women, or both?”And that’s it. And then maybe use birth control, and don’t get an STD, thinking about herpes, syphilis, gonorrhea, and chlamydia. We weren’t really trained to talk to patients about what kind of sex they are having, or how to talk to patients in a way that is open-minded but also safety-conscious and how the concept of safe sex is more than wear a condom and use birth control.

This idea of rough sex practices and how to talk to teenagers — maybe our pediatricians should be talking about this. Where do we start in terms of how to bring up these conversations and with what level of detail? 

Dr. Herbenick: We find that some young people are already being asked about some of the effects that might be showing on their bodies. It might be that their provider notices some bruising, or marks on their bodies from other types of rough sex practices like hitting and spanking. So that could be an entry point there. Choking is far more prevalent than slapping, so if you’re seeing some marks on the body, then it’s also a good time to ask about other practices they might be engaging in, especially higher risk ones like choking or strangulation. It’s offering some information and even saying, “Look, I’m not here to shame or judge you. I just want you to have some information about this” and giving them an opportunity to ask questions, too. 

We have found that almost nobody talks with their nurse or doctor, even if they have symptoms after being choked or strangled during sex. Just 1% of women with choking-related symptoms, 7% of men, and far fewer trans and nonbinary young people report talking with a nurse or doctor, mostly because they say it doesn’t seem like a big deal. The symptoms got better quickly. Sometimes they’re afraid of being shamed for their sexual behavior, and that’s why they say they don’t talk with somebody. 

They need some type of open-door anticipatory guidance as a way forward. Not everyone is comfortable directly asking whether a patient is engaging in this, but at least letting people know that you’ve heard of this behavior and providing some medical facts can give us a step forward with creating these conversations. 

Dr. Rubin: Can you tell us where is this research going in terms of next steps? Other things that you’re looking at? And what are you excited about? 

Dr. Herbenick: I’m excited about some work I did with a collaborator and colleague of mine, Dr. Keisuke Kawata, that he led a couple of years ago. He’s a neuroscientist. We were looking at potential cumulative effects on the brain. Now we’re taking some of that research into its next steps. We’re also doing more focused studies on other health consequences and hopefully finding out how we can test different educational messages and get people to learn more fact-based information about this, and then see if that is effective in prevention. 

Dr. Rubin: It sounds like a public health campaign is really needed about how to get the word out there about the health consequences of these activities. We’re asking people often enough. In my clinic, I try to keep it open-ended — tell me what sex looks like. What does it look like, and what do you want it to look like? Because I see a lot of people with problems, but if they don’t bring it to me, I don’t necessarily bring it up to them. Until I heard your lecture, and I thought, oh my gosh, I’m not even asking the right questions. Are you hopeful that there will be more public health messaging out there? 

Dr. Herbenick: I am. Years ago, when the child and adolescent choking game became a thing, the Centers for Disease Control and Prevention (CDC) issued reports about it and warnings to parents. And this is a far, far higher prevalence than that ever was. So, I would love to see organizations like the CDC and medical groups getting involved and educating their members and making statements. This is really impacting a huge generation of girls and women, because when it happens during sex between women and men, the choking is mostly happening to the girls and women. It’s also prevalent among sexual minority individuals. But we are talking about this whole generation of young women and what’s happening to their bodies and their brain health. We really need to step into this conversation. 

Dr. Rubin: Very few of us are sexual medicine–trained physicians, and very few of us feel confident and comfortable talking about sexual health issues. But people are getting hurt. People are having real consequences of these behaviors because of our lack of education, knowledge, and even discussion around it. So thank you for doing this research, because had you not done this research, we wouldn’t have found out that 64% of people are engaging in these types of activities. That is not rare.

Lenacapavir, a twice-yearly injectable HIV-1 capsid inhibitor, has shown 100% efficacy in preventing HIV in women at a high risk for infection, according to an interim analysis of the phase 3 PURPOSE 1 trial.

The results were so promising that the independent data monitoring committee recommended that Gilead Sciences stop the blinded phase of the trial and offer open-label lenacapavir to all participants.

The results were both unexpected and exciting. “I’ve been in the HIV field for a really long time, and there’s no other phase 3 PrEP trial that found zero infections,” said Moupali Das, MD, PhD, executive director of clinical development at Gilead Sciences, Foster City, California.

PURPOSE 1 is evaluating the safety and efficacy of two regimens — twice-yearly subcutaneous lenacapavir for pre-exposure prophylaxis and once-daily oral Descovy (emtricitabine 200 mg and tenofovir alafenamide 25 mg) — in women and girls aged 16-25 years. The two drugs are being compared with the standard once-daily oral Truvada (emtricitabine 200 mg and tenofovir disoproxil fumarate 300 mg).

There were no cases of HIV infection among the more than 2000 women in the lenacapavir group; in contrast, the incidence of HIV in the Descovy group was 2.02 per 100 person-years and in the Truvada group was 1.69 per 100 person-years.

The background incidence of HIV, one of the primary endpoints of the trial, was 2.41 per 100 person-years with lenacapavir. All the drugs were shown to be safe and well tolerated, and the full interim data from the trial will be released at an upcoming conference, according to Dr. Das.
 

No New Cases

The medical community is “thrilled” with the results so far, said Monica Gandhi, MD, director of the UCSF-Gladstone Center for AIDS Research. “We have to wait for the full data, but so far, it has been 100% effective and far superior to other treatments.”

Dr. Gandhi said she is waiting to see more details on side effects and tolerability, as well as discontinuation rates in the trial and the reasons people dropped out. For example, lenacapavir tends to cause nodules to form under the skin, which are the depots from which the drug is released over the course of 6 months. Gandhi said she is interested in whether any participants found them bothersome enough to discontinue the treatment.

The global HIV epidemic is still ongoing, with 1.3 million new infections in 2022, and existing oral PrEP options, and even the long-acting injectable cabotegravir, have so far failed to make as much of a dent in infection rates as hoped, said Dr. Gandhi. “We’ve been waiting for another option.”

The twice-yearly lenacapavir shot is easy and convenient to administer, compared with oral PrEP. Many people — especially younger individuals such as those enrolled in PURPOSE 1 — find it difficult to remember to take the pills every day.
 

A Discreet Option

Many participants in the trial said that they were uncomfortable with the stigma that can be attached to HIV PrEP. They did not want people to see the pill bottle in their house or hear it rattling in their purse. So an injection given just twice a year in a doctor’s office is attractive.

“This is a discrete option. People were very excited about the privacy and not having to take daily pills,” said Dr. Das. “PrEP only works if you take it.”

Better adherence to the treatment regimen is likely one reason that lenacapavir outperformed oral PrEP. But lenacapavir also has a unique mechanism of action as a multistage viral capsid inhibitor, Dr. Das said. It targets the capsid both before and after the virus integrates into the nucleus, which could be another reason for its potency.

Although the results are encouraging, there is still some concern about how accessible the drug will be, especially in low- and middle-income countries where the burden of HIV is the highest. “No one has any clue on how Gilead plans to make this accessible,” said Dr. Gandhi.
 

Access Issues

The company has not signed up for the Medicines Patent Pool (MPP) to allow companies to manufacture generic formulations of lenacapavir, which Dr. Gandhi said is the traditional route to provide cheaper alternatives in poorer countries. The “disastrous” rollout of injectable cabotegravir, which is still not widely available in lower-income countries, is a worrying precedent.

Gilead Sciences confirmed that all 5300 participants in the PURPOSE 1 study will have the option to continue receiving lenacapavir until the drug is generally available in their country. The company has committed to ensuring a dedicated Gilead Sciences supply in the countries where the need is the greatest until voluntary licensing partners are able to supply high-quality, low-cost versions of lenacapavir.

And rather than going through the third-party MPP, Gilead Sciences is negotiating a voluntary licensing program directly with other partners to supply generic versions of the drug in poorer countries.

Lenacapavir is already approved for the treatment of multidrug-resistant HIV but is not yet approved for HIV prevention. A sister trial, PURPOSE 2, is ongoing and is testing lenacapavir in men who have sex with men and in transgender men, transgender women, and nonbinary individuals who have sex with partners assigned male at birth. Should those results, expected by the end of 2024 or early 2025, be positive, the company will move forward with regulatory filings for lenacapavir PrEP.

Three other trials are also ongoing. PURPOSE 3 and PURPOSE 4 are smaller US-based studies of women and people who inject drugs, and PURPOSE 5 is enrolling people at a high risk for HIV in France and the United Kingdom to provide European data for European regulators.
