Cancer

The US Food and Drug Administration (FDA) has expanded the indication for the Gardasil-9 (Merck) vaccine to include prevention of oropharyngeal and other head and neck cancers caused by HPV types 16, 18, 31, 33, 45, 52, and 58.

This new indication is approved under the FDA’s accelerated approval program and is based on the vaccine’s effectiveness in preventing HPV-related anogenital disease. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory clinical trial, which is currently underway.

“At Merck, working to help prevent certain HPV-related cancers has been a priority for more than two decades,” Alain Luxembourg, MD, director, clinical research, Merck Research Laboratories, said in a statement. “Today’s approval for the prevention of HPV-related oropharyngeal and other head and neck cancers represents an important step in Merck’s mission to help reduce the number of men and women affected by certain HPV-related cancers.”

This new indication doesn’t affect the current recommendations that are already in place. In 2018, a supplemental application for Gardasil 9 was approved to include women and men aged 27 through 45 years for preventing a variety of cancers including cervical, vulvar, vaginal, and anal cancer as well as genital warts. But cancers of the head and neck were not included.

The original Gardasil vaccine came on the market in 2006, with an indication to prevent certain cancers and diseases caused by HPV types 6, 11, 16, and 18. It is no longer distributed in the United States.

In 2014, the FDA approved Gardasil 9, which extends the vaccine coverage for the initial four HPV types as five additional types (31, 33, 45, 52, and 58), and its initial indication was for use in both men and women between the ages of 9 through 26 years.
 

Head and neck cancers surpass cervical cancer

More than 2 decades ago, researchers first found a connection between HPV and a subset of head and neck cancers (Curr Opin Oncol. 1999;11(3):191-199). The cancers associated with HPV also appeared to have a different biology and disease pattern, as well as a better prognosis, compared with those that were unrelated. HPV is now responsible for the majority of oropharyngeal squamous cell cancers diagnosed in the United States.

A study published last year found that oral HPV infections were occurring with significantly less frequency among sexually active female adolescents who had received the quadrivalent vaccine, as compared with those who were unvaccinated.

These findings provided evidence that HPV vaccination was associated with a reduced frequency of HPV infection in the oral cavity, suggesting that vaccination could decrease the future risk of HPV-associated head and neck cancers.

The omission of head and neck cancers from the initial list of indications for the vaccine is notable because, according to data from the Centers for Disease Control and Prevention (CDC), oropharyngeal cancers are now the most common malignancy caused by HPV, surpassing cervical cancer.
 

Who will benefit?

An estimated 14 million new HPV infections occur every year in the United States, according to the CDC, and about 80% of individuals who are sexually active have been exposed at some point during their lifetime. In most people, however, the virus will clear on its own without causing any illness or symptoms.

In a Medscape videoblog, Sandra Adamson Fryhofer, MD, MACP, FRCP, helped clarify the adult population most likely to benefit from the vaccine. She pointed out that the HPV vaccine doesn’t treat HPV-related disease or help clear infections, and there are currently no clinical antibody tests or titers that can predict immunity.

“Many adults aged 27-45 have already been exposed to HPV early in life,” she said. Those in a long-term mutually monogamous relationship are not likely to get a new HPV infection. Those with multiple prior sex partners are more likely to have already been exposed to vaccine serotypes. For them, the vaccine will be less effective.”

Fryhofer added that individuals who are now at risk for exposure to a new HPV infection from a new sex partner are the ones most likely to benefit from HPV vaccination.
 

Confirmation needed

The FDA’s accelerated approval is contingent on confirmatory data, and Merck opened a clinical trial this past February to evaluate the efficacy, immunogenicity, and safety of the 9-valent HPV vaccine in men 20 to 45 years of age. The phase 3 multicenter randomized trial will have an estimated enrollment of 6000 men.

The U.S. Surgeon General is calling on all physicians to help patients stop smoking, noting that two-thirds of adult smokers say they want to quit, but only 40% report that their doctor has advised them to stop.

“I’ve got to own this as the nation’s doctor, and our health providers in this room and in this country need to own this stat,” said Surgeon General Jerome Adams, MD, at a press briefing releasing a new report on smoking cessation.

“Smoking is the No. 1 preventable cause of death, disease, and disability in the United States,” he said. “So why are 40% of our health providers out there not advising smokers to quit when they come in?”

In the first U.S. Surgeon General report on smoking cessation in 30 years, the 700-page report suggests smoking cessation-related quality measures that include physician reimbursement would increase treatment.

The evidence also suggests that using electronic health records to prompt clinicians to inquire about smoking would increase cessation treatment.

EHRs could be used to “empower and enable” physicians to advise people to quit, said Dr. Adams. Physicians also need “the education and the confidence to be able to have that conversation, because too many of them look at someone and say: ‘Nope, too hard, too much effort, no, that’s not what they’re here for today,’ ” he said.

However, “simply asking, advising, and referring can be enough to get someone on the pathway to quitting,” Dr. Adams said.
 

34 million still smoke

The new report is the first on the topic released since 1990, and the 34th on tobacco control since the first one was issued in 1964, said Dr. Adams. Since that first report, adult smoking has declined 70%, but some 34 million Americans (14%) still smoke, he said.

In addition, Dr. Adams said that many subpopulations have been left behind, noting: “Cigarette smoking remains highest among LGBTQ adults, people with disabilities or limitations, American Indians and Alaska Natives, and people with mental health conditions or substance use disorders.”

He also noted that 40% of cigarettes are consumed by those with a mental illness or a substance use disorder.

Quitting is beneficial at any age and can add as much as a decade to life expectancy, the report notes. Quitting also reduces the risk of 12 cancers, cuts the risk of chronic obstructive pulmonary disease, and reduces cardiovascular and stroke morbidity and mortality.

Pregnant women who quit also reduce their own morbidity and mortality risk and that of unborn children and infants, the report says.

“We know more about the science of quitting than ever before. We can, and must, do more to ensure that evidence-based cessation treatments are reaching the people that need them,” said Dr. Adams.

Less than one-third of those who have quit have used Food and Drug Administration–approved cessation medications or behavioral counseling, Dr. Adams said.
 

Barriers to care

Despite the existence of five nicotine replacement therapies and two nonnicotine oral medications, and more widespread availability of proven counseling methods – including web- or text-based programs – barriers to access remain.

These include a lack of insurance coverage for comprehensive, evidence-based smoking cessation treatment, which, when offered, increases availability and use.

“These are cost-effective interventions,” said Dr. Adams. “It’s penny wise and pound foolish to not give someone access to what we know works,” he said.

Because of the diversity of e-cigarette products and the variety of ways they are used, coupled with little research, it’s not currently possible to determine whether they are, or are not, useful smoking cessation tools, the report notes.

However, experts who compiled the report found some evidence to suggest that e-cigarettes containing nicotine may be “associated with increased smoking cessation compared with the use of e-cigarettes not containing nicotine.”

Asked whether the report’s conclusions might be interpreted as supportive of e-cigarettes, Dr. Adams said the report focused on smoking cessation, not initiation.

“I’m terribly concerned about the clear data that shows youth are initiating tobacco product use with e-cigarettes,” he said.

The Trump administration’s current proposal to partially restrict sales of some flavored e-cigarettes “reflects the science,” and “a balance between a desire to really make sure that people aren’t initiating with these products, but also a desire to again try to maintain a pathway for adults who want to use these products to quit to use them,” Dr. Adams said.

The focus, said Dr. Adams, should not be on e-cigarettes and whether they do, or do not, work.

“People want to quit,” he said. “We know what works. Not enough of them are getting it, and there are terrible disparities in who is and who is not getting access to effective and evidence-based treatment – that’s the story here.”
