The thrombopoietic agent eltrombopag (Promacta) did more harm than good when given to adults with acute myeloid leukemia (AML) during standard induction chemotherapy, results of a randomized phase 2 trial show.

Patients who were randomly assigned to receive standard induction chemotherapy with daunorubicin and cytarabine plus eltrombopag had a higher incidence of serious adverse events and death from hemorrhage within 30 days of the last eltrombopag dose, compared with patients who received chemotherapy and placebo, reported Noelle Frey, MD, from the University of Pennsylvania in Philadelphia, and colleagues.

“Overall survival was also numerically longer in the placebo group, compared with the eltrombopag group. It remains unclear why there were more deaths, particularly due to hemorrhage within 30 days after the last dose of treatment, in the eltrombopag group,” they wrote in the Lancet Haematology.

The investigators had expected better results, based on eltrombopag’s demonstrated efficacy against thrombocytopenia (a common feature of AML, exacerbated by chemotherapy), and because of evidence suggesting that the thrombopoietin-receptor agonist might also have antileukemic properties.

They set out to test the safety, tolerability, and efficacy of eltrombopag added to standard induction therapy in patients with treatment-naive AML of any subtype except M3 (acute promyelocytic leukemia) or M7 (acute megakaryocytic leukemia).

Patients received chemotherapy with daunorubicin in a bolus intravenous infusion at a dose of 90 mg/m² on days 1-3 for patients 18-60 years of age, or 60 mg/m² for patients older than 60 years, plus cytarabine continuous intravenous infusion at a dose of 100 mg/m² on days 1-7. The 148 patients were randomized in groups of 74 each to receive either eltrombopag 200 mg (100 mg for patients of east Asian heritage) or placebo, once daily.

Eltrombopag was continued until platelet counts were 200 × 10⁹/L or higher, remission, or 42 days after the start of induction chemotherapy.

Grade 3 or 4 adverse events occurring in 10% or more of patients – a primary endpoint – were febrile neutropenia, which occurred in 42% of patients receiving eltrombopag, compared with 39% receiving placebo, decreased white blood cell count in 11% vs. 7%, and hypophosphatemia in 4% and 13%, respectively,

Serious adverse events occurred in 34% of patients on eltrombopag, compared with 20% on placebo. Similarly, 53% of patients receiving eltrombopag died, compared with 41% of patients receiving the placebo.

Most of the deaths were attributable to AML, including 19 patients (26%) on eltrombopag and 10 (14%) on placebo. Eleven patients on eltrombopag and four on placebo died within 30 days of the last dose of study treatment.

Hemorrhage accounted for the deaths of five patients on eltrombopag and three on placebo, and sepsis accounted for the deaths of five and six patients, respectively.

Both the incidence of thromboembolic events and mean change in left ventricular ejection fraction were similar between the groups.

Median overall survival was 15.4 months in the eltrombopag group vs. 25.7 months in the placebo group, although this difference was not statistically significant, likely because of the sample size.

The investigators were at a loss to explain why the eltrombopag-treated patients had numerically worse outcomes.

“In the present study, eltrombopag did not improve the time to platelet recovery or the incidences of grade 3-4 thrombocytopenia, neutropenia, or anemia, compared with placebo. Furthermore, the study did not reveal any differences in investigator-assessed response to treatment. These findings were unexpected given outcomes from previous studies of eltrombopag monotherapy in patients with myelodysplastic syndromes or acute myeloid leukemia,” they wrote.

Although the reasons behind the findings are unclear, “the data from this trial do not support a favorable benefit-risk profile for eltrombopag in combination with induction chemotherapy in patients with acute myeloid leukemia,” the investigators wrote.

The study was funded by Novartis. Dr. Frey reported nonfinancial support from Novartis during the conduct of the study and consultancy fees from Novartis outside of the submitted work. Multiple coauthors reported similar relationships with Novartis and/or other companies.

For patients with multiple myeloma that remains symptomatic within a year of starting therapy, neither a second autologous stem cell transplant nor more intensive consolidation therapy offered survival benefits superior to those seen with a single first autologous transplant and lenalidomide maintenance, reported investigators in a multicenter U.S. trial.

Among 758 patients with multiple myeloma (MM) who underwent standard induction therapy, followed by melphalan conditioning and autologous hematopoietic cell transplant (AHCT), there were no differences in either progression-free survival (PFS) or overall survival (OS) between the three treatment arms, reported Edward A. Stadtmauer, MD, from the University of Pennsylvania, Philadelphia, and his colleagues.

Patients were randomized to either lenalidomide (Revlimid) maintenance alone; consolidation therapy with four cycles of lenalidomide, bortezomib (Velcade), and dexamethasone (RVD), followed by lenalidomide maintenance; or second transplant followed by lenalidomide maintenance.

“Single AHCT followed by len[alidomide] remains the standard of care. Greater than 80% of patients were alive at 38 months, which highlights excellent contemporary outcomes of patients with MM when treated with a standard approach of a multidrug induction followed by AHCT consolidation and maintenance,” they wrote in the Journal of Clinical Oncology.

The investigators hypothesized that the use of thalidomide analogues and proteasome inhibitors used in first-line therapy, consolidation, and long-term maintenance after high-dose melphalan and AHCT would improve survival, compared with a second AHCT.

To test this idea, they enrolled 758 patients from 54 U.S. centers and randomized them to one of three post-transplant strategies prior to transplant conditioning with high-dose melphalan (200 mg/m²) and AHCT.


Roughly 25% of patients in each treatment arm had high-risk disease, defined as beta-2 microglobulin levels greater than 5.5 mg/L, high-risk cytogenetics, and deletion 13 detected by standard cytogenetics only. The remaining patients in each arm had standard-risk disease.

The patients, who were a median age of 56 years old, had symptomatic multiple myeloma 12 months from the start of therapy without disease progression. They were randomly assigned to either AHCT followed by a second transplant and lenalidomide maintenance (247 patients), single transplant followed by RVD and lenalidomide maintenance (254), or single AHCT plus lenalidomide maintenance (257).

There were no significant differences between the groups in the primary endpoint of PFS at 38 months, with rates of 58.5% for the dual AHCT plus lenalidomide group, 57.8% for AHCT/RVD/lenalidomide, and 53.9% for AHCT/lenalidomide. Respective OS rates also did not differ significantly, at 81.8%, 85.4%, and 83.7%.

Complete response rates at 1 year were 50.5%, 58.4%, and 47.1%, respectively.

The three regimens also were similar in their toxicity profiles and in the risk of second malignancies.

The trial was supported by grants from the National Institutes of Health, research groups, Celgene, and Millennium (Takeda) Pharmaceuticals. Dr. Stadtmauer reported ties to Celgene, Takeda, and other companies. Multiple coauthors reported relationships with industry.

WASHINGTON – The cardiovascular effects of androgen deprivation therapy (ADT) for men with advanced prostate cancer are less severe than once feared, but there is evidence to suggest that men with preexisting heart failure or a history of myocardial infarction could be at excess risk for death from cardiovascular causes when they receive ADT, according to a leading prostate cancer expert.

Neil Osterweil/MDedge News

“I think there are concerns about potential cardiovascular harm of ADT, and I think this has reduced ADT use, despite the fact that we know for most men it improves overall survival,” said Paul Nguyen, MD, a radiation oncologist at the Dana-Farber/Brigham and Women’s Cancer Center in Boston.

“In fact, when we looked recently at men with high-risk prostate cancer, this is a group where overall survival is improved by 50% if they get ADT – so it cuts the risk of death in half – but it turns out that nearly a quarter of those patients are not receiving ADT. I think that the concern about cardiovascular harm and the confusion as to where that data stands is a lot of what’s driving that right now,” he said at the American College of Cardiology’s Advancing the Cardiovascular Care of the Oncology Patient meeting.
 

Randomized trial data

Dr. Nguyen noted that the evidence suggesting that ADT can increase the risk of death from cardiovascular causes came largely from three major studies:

• A 2006 study of 73,196 Medicare enrollees aged 66 or older, which found that ADT with a gonadotropin-releasing hormone (GnRH) agonist was possibly associated with increased risk of incident diabetes and cardiovascular disease (J Clin Oncol. 2006 Sep 20;24[27]:4448-56.).
• A 2007 analysis of data from the Cancer of the Prostate Strategic Urologic Research Endeavor (CAPSURE) database on 3,262 men treated with radical prostatectomy and 1,630 men treated with radiation or cryotherapy for localized prostate cancer, which found that among those 65 and older the 5-year cumulative incidence of cardiovascular death was 5.5% for patients who received ADT, vs. 2% for those who did not (J Natl Cancer Inst. 2007 Oct 17;99[20]:1516-24).
• A 2007 study of 1,372 men in three randomized trials of radiation therapy with or without androgen suppression therapy up to 8 months in duration, which found that men 65 and older who received 6 months of androgen suppression had significantly shorter times to fatal MIs than did men who did not receive the therapy (J Clin Oncol. 2007;25[17]:2420-5).

These studies, combined with observational data, led to a 2010 consensus statement from the American Heart Association, American Cancer Society, and American Urological Association, with endorsement from the American Society for Radiation Oncology, which stated that “there may be a relation between ADT and cardiovascular events and death.”

Also in 2010, the Food and Drug Administration required new labeling on GnRH agonists warning of “increased risk of diabetes and certain cardiovascular diseases (heart attack, sudden cardiac death, stroke).”
 

Not unanimous

Two other large randomized studies (J Clin Oncol. 2008 Feb 1;26[4]:585-91 and J Clin Oncol. 2009 Jan 1;27[1]:92-9) and two retrospective studies (J Clin Oncol. 2009 Jul 20;27[21]:3452-8 and J Clin Oncol. 2011 Sep 10;29[26]3510-16) found no excess risk of cardiovascular disease from ADT, Dr. Nguyen said, prompting him and his colleagues to see whether they could get a better estimate of the actual risk.

They did so through a 2011 meta-analysis (JAMA. 2011;306[21]:2359-66) of data on 4,141 patients from eight randomized trials. They found that among patients with unfavorable-risk prostate cancer, ADT was not associated with an increased risk of cardiovascular death, but was associated with lower risks for both prostate-specific and all-cause mortality.
 

Subpopulations may still be at risk

Dr. Nguyen said that the principal finding of the meta-analysis, while reassuring, “doesn’t let ADT off the hook for metabolic events, diabetes which we know happens, and the possibility of nonfatal cardiac events.”

He noted that while ADT was not associated with cardiovascular disease in clinical trials, observational studies showed significantly increased risk for fatal or non-fatal MI.

One possible explanation for the difference is that observational studies included nonfatal MI, while randomized trials looked only at cardiovascular deaths. It’s also possible that ADT causes harm primarily in men with preexisting comorbidities, who are often excluded from or underrepresented in clinical trials.

Evidence from a 2009 study (JAMA. 2009 Aug 26;302[8]:866-73) showed that among men with clinical stage T1 to T3 noninvasive, nonmetastatic prostate cancer, neoadjuvant hormonal therapy with both a luteinizing hormone-releasing hormone (LHRH) agonist and a nonsteroidal antiandrogen was associated with increased risk for all-cause mortality for those with a history of coronary artery disease–induced heart failure, but not for men with either no comorbidities or only a single comorbidity such as hypertension, hypercholesterolemia, or diabetes.
 

Clinical considerations

The decision to treat men with prostate cancer with ADT is therefore a balancing act, Dr. Nguyen said.

“As the risk of prostate cancer death goes up, the benefit of ADT goes up. However, as the comorbidity level goes up, the potential cardiovascular harm of ADT goes up,” he said.

For patients at the extreme ends of each continuum, such as a patient with high-risk prostate cancer and no cardiovascular comorbidities or a patient with low-risk cancer but multiple CV risk factors, the decision to give or withhold ADT is relatively simple, he said.

But for patients in between, such as a man with intermediate-risk cancer and one risk factor or a man with high risk disease with multiple comorbidities, the decision is far more complex.

“This where I think the dialogue with the cardiologist really needs to come into this decision,” he said.

Evidence to support the decision comes from retrospective studies suggesting that even men with high-risk prostate cancer have poorer overall survival with ADT if they have a history of heart failure or MI.

For patients with low-risk cancer and diabetes, ADT is associated with worse overall survival, but ADT does not cause additional harm to men with intermediate- to high-risk prostate cancer who have concomitant diabetes, Dr. Nguyen said.

“My view is that ADT has not been shown to increase cardiovascular death in randomized trials, so I think that for the vast majority of patients it probably does not increase cardiovascular deaths. But I think there could very well be a vulnerable 5% of patients who might have an excess risk of cardiovascular death, and I think we have to be careful, but we still have to balance it out against their risks for prostate cancer death,” he said.

Two other large randomized studies (J Clin Oncol. 2008 Feb 1;26[4]:585-91 and J Clin Oncol. 2009 Jan 1;27[1]:92-9) and two retrospective studies (J Clin Oncol. 2009 Jul 20;27[21]:3452-8 and J Clin Oncol. 2011 Sep 10;29[26]3510-16) found no excess risk of cardiovascular disease from ADT, Dr. Nguyen said, prompting him and his colleagues to see whether they could get a better estimate of the actual risk.

They did so through a 2011 meta-analysis (JAMA. 2011;306[21]:2359-66) of data on 4,141 patients from eight randomized trials. They found that among patients with unfavorable-risk prostate cancer, ADT was not associated with an increased risk of cardiovascular death, but was associated with lower risks for both prostate-specific and all-cause mortality.
 

Subpopulations may still be at risk

Dr. Nguyen said that the principal finding of the meta-analysis, while reassuring, “doesn’t let ADT off the hook for metabolic events, diabetes which we know happens, and the possibility of nonfatal cardiac events.”

He noted that while ADT was not associated with cardiovascular disease in clinical trials, observational studies showed significantly increased risk for fatal or non-fatal MI.

One possible explanation for the difference is that observational studies included nonfatal MI, while randomized trials looked only at cardiovascular deaths. It’s also possible that ADT causes harm primarily in men with preexisting comorbidities, who are often excluded from or underrepresented in clinical trials.

Evidence from a 2009 study (JAMA. 2009 Aug 26;302[8]:866-73) showed that among men with clinical stage T1 to T3 noninvasive, nonmetastatic prostate cancer, neoadjuvant hormonal therapy with both a luteinizing hormone-releasing hormone (LHRH) agonist and a nonsteroidal antiandrogen was associated with increased risk for all-cause mortality for those with a history of coronary artery disease–induced heart failure, but not for men with either no comorbidities or only a single comorbidity such as hypertension, hypercholesterolemia, or diabetes.
 

Clinical considerations

The decision to treat men with prostate cancer with ADT is therefore a balancing act, Dr. Nguyen said.

“As the risk of prostate cancer death goes up, the benefit of ADT goes up. However, as the comorbidity level goes up, the potential cardiovascular harm of ADT goes up,” he said.

For patients at the extreme ends of each continuum, such as a patient with high-risk prostate cancer and no cardiovascular comorbidities or a patient with low-risk cancer but multiple CV risk factors, the decision to give or withhold ADT is relatively simple, he said.

But for patients in between, such as a man with intermediate-risk cancer and one risk factor or a man with high risk disease with multiple comorbidities, the decision is far more complex.

“This where I think the dialogue with the cardiologist really needs to come into this decision,” he said.

Evidence to support the decision comes from retrospective studies suggesting that even men with high-risk prostate cancer have poorer overall survival with ADT if they have a history of heart failure or MI.

For patients with low-risk cancer and diabetes, ADT is associated with worse overall survival, but ADT does not cause additional harm to men with intermediate- to high-risk prostate cancer who have concomitant diabetes, Dr. Nguyen said.

“My view is that ADT has not been shown to increase cardiovascular death in randomized trials, so I think that for the vast majority of patients it probably does not increase cardiovascular deaths. But I think there could very well be a vulnerable 5% of patients who might have an excess risk of cardiovascular death, and I think we have to be careful, but we still have to balance it out against their risks for prostate cancer death,” he said.

WASHINGTON – The cardiovascular effects of androgen deprivation therapy (ADT) for men with advanced prostate cancer are less severe than once feared, but there is evidence to suggest that men with preexisting heart failure or a history of myocardial infarction could be at excess risk for death from cardiovascular causes when they receive ADT, according to a leading prostate cancer expert.

“I think there are concerns about potential cardiovascular harm of ADT, and I think this has reduced ADT use, despite the fact that we know for most men it improves overall survival,” said Paul Nguyen, MD, a radiation oncologist at the Dana-Farber/Brigham and Women’s Cancer Center in Boston.

“In fact, when we looked recently at men with high-risk prostate cancer, this is a group where overall survival is improved by 50% if they get ADT – so it cuts the risk of death in half – but it turns out that nearly a quarter of those patients are not receiving ADT. I think that the concern about cardiovascular harm and the confusion as to where that data stands is a lot of what’s driving that right now,” he said at the American College of Cardiology’s Advancing the Cardiovascular Care of the Oncology Patient meeting.
 

Randomized trial data

Dr. Nguyen noted that the evidence suggesting that ADT can increase the risk of death from cardiovascular causes came largely from three major studies:

• A 2006 study of 73,196 Medicare enrollees aged 66 or older, which found that ADT with a gonadotropin-releasing hormone (GnRH) agonist was possibly associated with increased risk of incident diabetes and cardiovascular disease (J Clin Oncol. 2006 Sep 20;24[27]:4448-56.).
• A 2007 analysis of data from the Cancer of the Prostate Strategic Urologic Research Endeavor (CAPSURE) database on 3,262 men treated with radical prostatectomy and 1,630 men treated with radiation or cryotherapy for localized prostate cancer, which found that among those 65 and older the 5-year cumulative incidence of cardiovascular death was 5.5% for patients who received ADT, vs. 2% for those who did not (J Natl Cancer Inst. 2007 Oct 17;99[20]:1516-24).
• A 2007 study of 1,372 men in three randomized trials of radiation therapy with or without androgen suppression therapy up to 8 months in duration, which found that men 65 and older who received 6 months of androgen suppression had significantly shorter times to fatal MIs than did men who did not receive the therapy (J Clin Oncol. 2007;25[17]:2420-5).

These studies, combined with observational data, led to a 2010 consensus statement from the American Heart Association, American Cancer Society, and American Urological Association, with endorsement from the American Society for Radiation Oncology, which stated that “there may be a relation between ADT and cardiovascular events and death.”

Also in 2010, the Food and Drug Administration required new labeling on GnRH agonists warning of “increased risk of diabetes and certain cardiovascular diseases (heart attack, sudden cardiac death, stroke).”

WASHINGTON – Oncologists and cardiologists need to work hand-in-hand when managing the care of women with breast cancer whose treatment plan includes cardiotoxic therapies and breast irradiation, reported specialists.

Neil Osterweil/MDedge News

Depending on the cancer subtype, women with breast cancer may receive chemotherapy with a cardiotoxic anthracycline such as doxorubicin or epirubicin, or a HER2-targeted agent such as trastuzumab (Herceptin), pertuzumab (Perjeta), or ado-trastuzumab emtansine (Kadcyla).

“The cardiotoxicity related to breast cancer has been a well publicized issue, and chances are your patients know about it and are concerned as well,” Jennifer E. Liu, MD, director of cardiovascular laboratories at Memorial Sloan Kettering Cancer Center in New York, said at the American College of Cardiology’s Advancing the Cardiovascular Care of the Oncology Patient meeting.
 

Anthracyclines, trastuzumab, and HF

In large adjuvant therapy trials of anthracyclines and trastuzumab in women with breast cancer, doxorubicin alone was associated with an asymptomatic decline in left ventricular ejection fraction (LVEF) of 4% to 11%, and a less than 1% incidence of heart failure (HF), Dr. Liu noted.

When patients received an anthracycline followed by trastuzumab, the incidence of asymptomatic LVEF decline ranged from 4% to 19%, the incidence of clinical HF was 2% to 4%, and the rate of trastuzumab interruption for cardiac adverse events ranged from 5% to 18%.

In comparison, in trials with trastuzumab in combination therapy that did not contain an anthracycline, the risk of cardiovascular complications was lower, with asymptomatic decline in LVEF ranging from 3.2% to 9.4%, and class III/IV HF occurring in just 0.5% of patients. In trials combining trastuzumab and pertuzumab, there were no increases in cardiac toxicity over trastuzumab alone.

Although with longer follow-up, the approximately 4% rate of HF in patients treated with anthracycline-based chemotherapy, paclitaxel, and trastuzumab in the NSABP B-31 trial has not changed significantly; retrospective claims-based studies reflecting daily practice have shown significantly higher rates of HF and or cardiomyopathy, Dr. Liu said.

She cited a 2012 study showing that among 45,537 women with a mean age of 76 years who were treated for breast cancer, the 3-year incidence rates of HF and/or cardiomyopathy were 32% for patients treated with trastuzumab alone, and 41.9% for those treated with an anthracycline followed by trastuzumab. Other, smaller studies also showed lower but significantly elevated risks for the drugs.

The discrepancy between clinical trial and “real world” results may be chalked up to the fact that claims-based data rely on diagnostic codes that may not accurately reflect the actual cardiac diagnosis, and by the fact that clinical trials have strict entry criteria that exclude patients with cardiovascular disease, she said.
 

Radiation risks

Radiation therapy is associated with a more than 7% increase in major coronary events per Gy of mean heart dose, Dr. Liu noted, citing a 2013 study (N Engl J Med. 2013;368:987-98).

Paul Nguyen, MD, a radiation oncologist at the Dana-Farber/Brigham and Women’s Cancer Center in Boston, said that risk factors for radiation-induced heart disease include anterior or left chest irradiation, cumulative doses above 30 Gy, patient age younger than 50 years, doses of more than 2 Gy per fraction, presence and extent of tumor in or near the heart, lack of radiation shielding, concomitant chemotherapy (especially with anthracyclines), and preexisting cardiovascular disease or risk factors.

Treatment options for LVEF decline

The package insert for trastuzumab recommends withholding the drug for a minimum of 4 weeks if the patient has a 16% or greater decline in LVEF from baseline, or a 10% or greater decline from baseline to below the lower limit of normal. The insert recommends LVEF monitoring every 3 or 4 weeks, and says that trastuzumab can be resumed if LVEF improves to above the lower limit of normal with an absolute decrease from baseline of not more than 15%. The insert also states, however, that “the safety of continuation or resumption of trastuzumab in patients with trastuzumab induced LV dysfunction has never been studied, “ Dr. Liu noted.

She cited an American Society of Clinical Oncology guideline on the prevention and monitoring of cardiac dysfunction in survivors of adult cancers, which states in part that the decision to continue or discontinue cancer therapy in patients with evidence of cardiac dysfunction “made by the oncologist, should be informed by close collaboration with a cardiologist, fully evaluating the clinical circumstances and considering the risks and benefits of continuation of therapy responsible for the cardiac dysfunction.”

“I want to emphasize the importance of accepting and managing cardiovascular risk in patients priors to and during potentially cardiotoxic therapy. To optimize cardiologic and oncologic outcomes, we need to avoid or minimize treatment interruptions of life-saving therapy, and mitigate cardiac events with aggressive cardiovascular risk-factor modification,” Dr. Liu said.

She called for development of better risk stratification tools to tailor cardiac surveillance during therapy, based on both patient-specific and treatment-specific risk factors.

Dr. Liu reported nothing to disclose. Dr. Nguyen reported consulting fees/honoraria from Astellas, Augmenix, Blue Earth Diagnostics. Cota, Dendreon, Ferring Pharmaceuticals. GenomeDx, Janssen, and Nanobiotix.

WASHINGTON – Unquestionably, immunotherapy is revolutionizing the care of patients with various solid tumors and hematologic malignancies.

Neil Osterweil/MDedge News

But it’s equally true that there’s no such thing as either a free lunch or a cancer therapy free of side effects, whether it’s increased risk for heart failure associated with anthracycline-based chemotherapy, or inflammatory conditions, arrhythmias, and thromboembolic events associated with immune checkpoint inhibitors, said R. Frank Cornell, MD, of Vanderbilt University Medical Center in Nashville, Tenn.

“Early awareness and intervention is critical for improved outcomes, and a multidisciplinary approach between oncology, cardiology, the clinic nurse, and other health care providers is critical in managing these patients with these complicated therapies,” he said at the American College of Cardiology’s Advancing the Cardiovascular Care of the Oncology Patient meeting.
 

Checkpoint inhibitors and the heart

Toxicities associated with immune checkpoint inhibitors such as the programmed death 1/ligand 1 (PD-1/PD-L1) inhibitors nivolumab (Opdivo) and pembrolizumab (Keytruda) and the cytotoxic T-lymphocyte antigen 4 antibody ipilimumab (Yervoy) tend to mimic autoimmune conditions, Dr. Cornell said.

Cardiovascular events associated with these agents, while uncommon, include myocarditis, pericarditis, arrhythmias, impaired ventricular function with heart failure, vasculitis, and venous thromboembolism, he said, citing an American Society of Clinical Oncology (ASCO) clinical practice guideline (J Clin Oncol 2018;36[17]:1714-68).

Dr. Cornell described the case of a 63-year-old woman with disseminated metastatic melanoma who presented to the emergency department 10 days after starting on combination therapy with ipilimumab and nivolumab. She had developed shortness of breath, pleuritic chest pain, and a mild cough for 1 or 2 days.

Her cardiac laboratory markers had been normal at baseline, but were markedly elevated on presentation, and electrocardiograms showed complete heart block and subsequent ventricular tachycardia.

The patient was started on high-dose prednisone, but she died in hospital, and an autopsy showed that the cause of death was infiltration into the myocardium of CD3-positive and CD8-positive T lymphocytes.

“So how do we manage this? This is a good opportunity, I think, for further cardiology and oncology collaboration to develop more robust guidelines for what we can do to best prevent this,” Dr. Cornell said.

Patients started on the ipilimumab/nivolumab combination should be tested weekly for cardiac troponin, creatine kinase (CK) and CK-muscle/brain (CK-MB) weekly for the first 3-4 weeks of therapy. Therapy should be stopped if troponin levels continue to rise, and the patient should be started on high-dose steroids, he said.

The role of other anti-inflammatory agents such as infliximab (Remicade and biosimilars) is unclear and needs further study, he added.

Dr. Cornell cited a 2018 letter to The Lancet by Javid J. Moslehi, MD, and colleagues from Vanderbilt describing an increase in reports of fatal myocarditis among patients treated with checkpoint inhibitors.

“We highlight the high mortality rate with severe immune checkpoint inhibitor–related myocarditis, which is more frequent with combination PD-1 and CTLA-4 blockade, but can also occur with monotherapy. Myocarditis was observed across immune checkpoint inhibitor regimens, although it remains too early to determine whether the incidence differs between use of anti-PD1 and anti-PD-L1 drugs. Furthermore, this condition occurs early on during therapy and across cancer types,” they wrote.

Most of the patients had no preexisting cardiovascular disease, and most were not taking medications for hypertension, cardiovascular disease, or diabetes.
 

CAR-T cells and cardiac disease

The primary cardiac complications associated with CAR-T cell therapy are related to the cytokine release syndrome (CRS), a condition marked by progressive elevation in inflammatory cytokines that in turn leads to marked elevations in C-reactive protein (CRP), interferon gamma, tumor necrosis factor al, and release of pro-inflammatory cytokines including interleukin (IL) 6, IL-10, IL-12, and IL-1 beta.

In rare instances, CRS can lead to disseminated intravascular coagulation (DIC), capillary leak syndrome, and a hemophagocytic lymphohistiocytosis-like (HLH) syndrome, Dr. Cornell said.

Package inserts for the two Food and Drug Administration–approved CAR-T cell products, axicabtagene ciloleucel (Yescarta) and tisagenlecleucel (Kymriah) show that each was associated in clinical trials with a high incidence of CRS.

Among patients treated with axicabtagene ciloleucel, 94% developed CRS, which was grade 3 or greater in severity in 13%. The median time to onset was 2 days, and the median duration was 7 days. Cardiovascular adverse events included grade 3 or greater tachycardia in 2%, arrhythmias in 7%, edema in 1%, dyspnea in 3%, pleural effusion in 2%, hypotension in 15%, hypertension in 6%, and thrombosis in 1%.

Among patients treated with tisagenlecleucel, 79% treated for B-cell acute lymphoblastic leukemia (B-ALL) and 74% treated for diffuse large B cell lymphoma (DLBCL) developed CRS, which was grade 3 or greater in 49% and 23% of patients, respectively. The median time to onset was 3 days, and the median duration of CRS was 8 days.

Cardiovascular adverse events of grade 3 or greater among these patients included tachycardia in 4%, fluid overload in 7%, edema in 1%, dyspnea in 12%, pulmonary edema in 4%, hypotension in 22%, and hypertension in 6%.

Risk factors for CRS include high pre-infusion tumor burden, active infections, and concurrent inflammatory processes, Dr. Cornell said.

Prevention of cardiovascular complications of CAR-T cell therapy requires management of CRS. Patients with grade 2 or greater CRS should receive the anti-IL-6 agent tocilizumab (Actemra) 8 mg/kg intravenously over 1 hour to a maximum dose of 800 mg. Tocilizumab infusions can be repeated every 8 hours as needed if the patient is not responsive to intravenous fluids or increasing supplement oxygen, but should be limited to a maximum of three doses over 24 hours, and a maximum total of four doses.

Patients with grade 3 CRS should also receive intravenous methylprednisolone 1 mg/kg twice daily or the equivalent amount of dexamethasone, with corticosteroids continued until the severity of CRS is grade 1 or less, then tapered over 3 days,

Patients with grade 4 CRS should also receive IV methylprednisolone 1,000 mg per day for 3 days, and if symptoms improve, continue management as per grade 3, Dr. Cornell said.

Dr. Cornell reported having nothing to disclose.

“Early awareness and intervention is critical for improved outcomes, and a multidisciplinary approach between oncology, cardiology, the clinic nurse, and other health care providers is critical in managing these patients with these complicated therapies,” he said at the American College of Cardiology’s Advancing the Cardiovascular Care of the Oncology Patient meeting.
 

Checkpoint inhibitors and the heart

Toxicities associated with immune checkpoint inhibitors such as the programmed death 1/ligand 1 (PD-1/PD-L1) inhibitors nivolumab (Opdivo) and pembrolizumab (Keytruda) and the cytotoxic T-lymphocyte antigen 4 antibody ipilimumab (Yervoy) tend to mimic autoimmune conditions, Dr. Cornell said.

Cardiovascular events associated with these agents, while uncommon, include myocarditis, pericarditis, arrhythmias, impaired ventricular function with heart failure, vasculitis, and venous thromboembolism, he said, citing an American Society of Clinical Oncology (ASCO) clinical practice guideline (J Clin Oncol 2018;36[17]:1714-68).

Dr. Cornell described the case of a 63-year-old woman with disseminated metastatic melanoma who presented to the emergency department 10 days after starting on combination therapy with ipilimumab and nivolumab. She had developed shortness of breath, pleuritic chest pain, and a mild cough for 1 or 2 days.

Her cardiac laboratory markers had been normal at baseline, but were markedly elevated on presentation, and electrocardiograms showed complete heart block and subsequent ventricular tachycardia.

The patient was started on high-dose prednisone, but she died in hospital, and an autopsy showed that the cause of death was infiltration into the myocardium of CD3-positive and CD8-positive T lymphocytes.

“So how do we manage this? This is a good opportunity, I think, for further cardiology and oncology collaboration to develop more robust guidelines for what we can do to best prevent this,” Dr. Cornell said.

Patients started on the ipilimumab/nivolumab combination should be tested weekly for cardiac troponin, creatine kinase (CK) and CK-muscle/brain (CK-MB) weekly for the first 3-4 weeks of therapy. Therapy should be stopped if troponin levels continue to rise, and the patient should be started on high-dose steroids, he said.

The role of other anti-inflammatory agents such as infliximab (Remicade and biosimilars) is unclear and needs further study, he added.

Dr. Cornell cited a 2018 letter to The Lancet by Javid J. Moslehi, MD, and colleagues from Vanderbilt describing an increase in reports of fatal myocarditis among patients treated with checkpoint inhibitors.

“We highlight the high mortality rate with severe immune checkpoint inhibitor–related myocarditis, which is more frequent with combination PD-1 and CTLA-4 blockade, but can also occur with monotherapy. Myocarditis was observed across immune checkpoint inhibitor regimens, although it remains too early to determine whether the incidence differs between use of anti-PD1 and anti-PD-L1 drugs. Furthermore, this condition occurs early on during therapy and across cancer types,” they wrote.

Most of the patients had no preexisting cardiovascular disease, and most were not taking medications for hypertension, cardiovascular disease, or diabetes.
 

CAR-T cells and cardiac disease

The primary cardiac complications associated with CAR-T cell therapy are related to the cytokine release syndrome (CRS), a condition marked by progressive elevation in inflammatory cytokines that in turn leads to marked elevations in C-reactive protein (CRP), interferon gamma, tumor necrosis factor al, and release of pro-inflammatory cytokines including interleukin (IL) 6, IL-10, IL-12, and IL-1 beta.

In rare instances, CRS can lead to disseminated intravascular coagulation (DIC), capillary leak syndrome, and a hemophagocytic lymphohistiocytosis-like (HLH) syndrome, Dr. Cornell said.

Package inserts for the two Food and Drug Administration–approved CAR-T cell products, axicabtagene ciloleucel (Yescarta) and tisagenlecleucel (Kymriah) show that each was associated in clinical trials with a high incidence of CRS.

Among patients treated with axicabtagene ciloleucel, 94% developed CRS, which was grade 3 or greater in severity in 13%. The median time to onset was 2 days, and the median duration was 7 days. Cardiovascular adverse events included grade 3 or greater tachycardia in 2%, arrhythmias in 7%, edema in 1%, dyspnea in 3%, pleural effusion in 2%, hypotension in 15%, hypertension in 6%, and thrombosis in 1%.

Among patients treated with tisagenlecleucel, 79% treated for B-cell acute lymphoblastic leukemia (B-ALL) and 74% treated for diffuse large B cell lymphoma (DLBCL) developed CRS, which was grade 3 or greater in 49% and 23% of patients, respectively. The median time to onset was 3 days, and the median duration of CRS was 8 days.

Cardiovascular adverse events of grade 3 or greater among these patients included tachycardia in 4%, fluid overload in 7%, edema in 1%, dyspnea in 12%, pulmonary edema in 4%, hypotension in 22%, and hypertension in 6%.

Risk factors for CRS include high pre-infusion tumor burden, active infections, and concurrent inflammatory processes, Dr. Cornell said.

Prevention of cardiovascular complications of CAR-T cell therapy requires management of CRS. Patients with grade 2 or greater CRS should receive the anti-IL-6 agent tocilizumab (Actemra) 8 mg/kg intravenously over 1 hour to a maximum dose of 800 mg. Tocilizumab infusions can be repeated every 8 hours as needed if the patient is not responsive to intravenous fluids or increasing supplement oxygen, but should be limited to a maximum of three doses over 24 hours, and a maximum total of four doses.

Patients with grade 3 CRS should also receive intravenous methylprednisolone 1 mg/kg twice daily or the equivalent amount of dexamethasone, with corticosteroids continued until the severity of CRS is grade 1 or less, then tapered over 3 days,

Patients with grade 4 CRS should also receive IV methylprednisolone 1,000 mg per day for 3 days, and if symptoms improve, continue management as per grade 3, Dr. Cornell said.

Dr. Cornell reported having nothing to disclose.

Here’s a novel idea: Help patients figure out how large a bite health care will take from their life savings.

A pilot study of a randomized intervention showed that practice-based counseling of patients about the actual out-of-pocket costs of chemotherapy is both “feasible and acceptable.”

But the larger question about whether any of it does any good remains unanswered, reported Sheetal M. Kircher, MD, from Northwestern University in Chicago and her colleagues.

“The majority of participants found the FC [financial counseling] consultation helpful, but they felt the same about their finances after the intervention. Although it is reassuring that no participants felt worse about their cancer costs after the intervention, the variability in perceived value of the FC consultation highlights that the content of a financial intervention needs to be tailored to the patient’s individual needs,” they wrote in the Journal of Oncology Practice.

The investigators conducted a randomized trial with 95 patients at the Robert H. Lurie Comprehensive Cancer Center at Northwestern to study whether financial counseling about the estimated total costs to them of one cycle of chemotherapy could help patients weather financial distress.

The participants first completed a baseline assessment of their financial distress, health-related quality of life, and degree of health insurance literacy. They were then randomized to either standard of care or to a financial-counseling intervention consisting of education, financial-assistance screening, and a tool for estimating total billed charges and out-of-pocket costs. Participants in the experimental arm received a phone call and in-person visit from a financial counselor.

Financial distress was measured using the Comprehensive Score for Financial Toxicity (COST), InCharge Financial Distress/Financial Well-Being Scale, and a single European Organisation for Research and Treatment of Cancer (EORTC) question.

Patients in the standard-of-care arm had access to financial counselors on request, but they were not automatically assigned counseling.

Of the 95 patients randomized, 65 completed both the baseline and follow-up assessments. The investigators noted that participants tended to have more advanced disease; six patients in the standard-of-care arm and five in financial-counseling arm died before they could complete the follow-up assessment.

Of the 43 participants randomized to counseling, 42 (98%) completed the phone call, 20 (47%) completed the in-person visit, and 13 (30%) completed the entire intervention.

At the second, follow-up assessment, 83% of participants in the counseling arm said they were comfortable with answering questions about how the costs of treatment affected their pocketbooks, and 76% reported that they did not have difficulty understanding the estimation tool, and 88% said that the financial counselor helped them to understand their out-of-pocket costs “somewhat” or “a lot.”

However, when they were asked how they felt about paying for their care after completing the intervention, 76% said they felt about the same, 18% said they felt “a little better,” and only 6% said they felt “much better.”

In addition there were no statistically significant differences in any of the financial distress measures between the intervention and standard-of-care groups.

The investigators speculated that the study was underpowered to detect differences in COST (financial toxicity) scores.

High financial distress was significantly associated with worse emotional functioning (P = .0189), whereas being married or in a cohabiting relationship was associated with less financial distress (P = .0092).

“Future studies should aim to better understand patient perspectives and preferences around discussing transparent cost data and design system-level interventions to identify and assist patients efficiently with their specific financial concerns,” Dr. Kircher and her colleagues concluded.

The study was supported by the Robert H. Lurie Comprehensive Cancer Center and the Cancer Survivorship Institute of Northwestern University. Dr. Kircher disclosed stock or ownership interest in Penrose TherapeuTx. Five coauthors reported research funding, travel expenses, and/or honoraria from multiple other companies, as well as consulting/roles.

Oncologists should consider testing all patients with newly diagnosed cancers for infection with the hepatitis B and C viruses, a multicenter team has recommended.

A prospective study of hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV infections among 3,051 patients with newly diagnosed cancers showed that 6.5% of patients tested positive for previous HBV and 0.6% had chronic HBV infection. In addition, 2.4% of patients were positive for HCV, and 1.1% for HIV infections, reported Scott D. Ramsey, MD, PhD, from the Fred Hutchinson Cancer Research Center in Seattle, and colleagues.

“Many patients had no known risk factors for infection, suggesting that current risk-based models for screening may be insufficient. Thus, we believe our results warrant consideration of universal testing of patients with newly diagnosed cancer for HBV and HCV infection, particularly if such an approach is shown to be cost effective,” they wrote in JAMA Oncology.

The investigators noted that patients with undiagnosed hepatitis and/or HIV infections could transmit them to unsuspecting caregivers, adding that “with effective treatments available, not screening for these viruses misses an opportunity to reduce future morbidity associated with these infections and to avoid viral reactivation during treatment, with resulting morbidity and mortality.”

To estimate the prevalence of the infections in patients with newly diagnosed cancers, investigators looked at a cohort of 3,051 patients with a cancer diagnosis made within the previous 120 days at nine academic medical centers and nine community oncology centers representing a total of 41 cancer clinics affiliated with the SWOG Cancer Research Network (formerly the Southwest Oncology Group).

The median patient age was 60.6 years. Female patients constitute 60.4% of the sample; 18.1% were black, and 18.3% were of Hispanic heritage.

Of 3,050 patients for whom HBV testing results were available, 6.5% (197) were positive for previous HBV infection, compared with an estimated U.S. population prevalence of 4.7%. In addition, 0.6% (19 patients) were found to have chronic HBV, compared with an estimated 0.3% US population prevalence.

HCV infections were detected in 2.4% (71 of 2990 patients), compared with an estimated population prevalence of 1.3%, and HIV infections were detected in 1.1%, compared with a background estimated population prevalence of 0.3%.

In all, 32 patients were diagnosed with viral infections by testing performed for the study, including 8 patients with chronic HBV, 22 with HCV, and 2 with HIV.

Additionally, the authors found that 4 patients with chronic HBV, 23 with HCV, and 7 with HIV had no identifiable risk factors.

The highest prevalence of infections occurred among patients with liver cancer, nonliver and noncolorectal cancers of the gastrointestinal tract, head and neck cancers, lung cancers, and prostate cancer. A finding of viral positivity changed the treatment plan in only 8% of all infected patients, however.

“Given that most HIV-infected patients in our study knew their viral status, the yield of universal HIV testing among patients with newly diagnosed cancer may likely be low. Although age-directed screening is recommended for HIV and HCV, uptake rates in primary care are variable and low overall,” Dr. Ramsey and his colleagues wrote.

The study was supported by grants from the National Cancer Institute. Dr. Ramsey and several co-authors reported receiving NCI grants, and multiple co-authors reported grants and/or consulting fees from various companies.

The highest prevalence of infections occurred among patients with liver cancer, nonliver and noncolorectal cancers of the gastrointestinal tract, head and neck cancers, lung cancers, and prostate cancer. A finding of viral positivity changed the treatment plan in only 8% of all infected patients, however.

“Given that most HIV-infected patients in our study knew their viral status, the yield of universal HIV testing among patients with newly diagnosed cancer may likely be low. Although age-directed screening is recommended for HIV and HCV, uptake rates in primary care are variable and low overall,” Dr. Ramsey and his colleagues wrote.

The study was supported by grants from the National Cancer Institute. Dr. Ramsey and several co-authors reported receiving NCI grants, and multiple co-authors reported grants and/or consulting fees from various companies.

Breast cancer survivors should continue to be monitored for hematologic malignancies, especially acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), results of a population-based study from France suggest.

Among nearly 440,000 women with an incident breast cancer diagnosis, the incidence of AML was nearly three times higher and the incidence of MDS was five times higher than that of women in the general population. Women with breast cancer also were at higher risk for multiple myeloma (MM) and acute lymphoblastic leukemia/lymphocytic lymphoma (ALL/LL) compared with the background population, reported Marie Joelle Jabagi, PharmD, MPH, of the University of Paris Sud, France, and her colleagues.

“These findings serve to better inform practicing oncologists, and breast cancer survivors should be advised of the increased risk of developing certain hematologic malignant neoplasms after their first cancer diagnosis,” they wrote in JAMA Network Open.

Breast cancers are the malignant solid tumors most frequently associated with risk for myeloid neoplasms, but there is little information on the risk for secondary lymphoid malignancies among breast cancer patients, the investigators stated.

“In addition, real-life data on secondary hematologic malignant neoplasm incidence are scarce, especially in the recent period marked by major advances in breast cancer treatments,” they wrote.

To get better estimates of the incidence of myeloid and lymphoid neoplasms in this population, they conducted a retrospective review of information from the French National Health Data System on all French women from the ages of 20 to 85 years who had an incident breast cancer diagnosis from July 1, 2006, through Dec. 31, 2015.

In all, 439,704 women with a median age of 59 years were identified. They were followed until a diagnosis of a hematologic malignancy, death, or loss to follow-up, or until Dec. 31, 2016.

Data on the breast cancer patients were compared with those for all French women in the general population who were registered in the general national health insurance program from January 2007 through the end of 2016.

During a median follow-up of 5 years, there were 3,046 cases of hematologic neoplasms among the breast cancer patients, including 509 cases of AML, for a crude incidence rate (CIR) of 24.5 per 100,000 person-years (py); 832 cases of MDS for a CIR of 40.1/100,000 py; and 267 cases of myeloproliferative neoplasms (MPN), for a CIR of 12.8/100,000 py.

In addition, there were 420 cases of MM for a CIR of 20.3/100,000 py; 912 cases of Hodgkin or non-Hodgkin lymphoma (HL/NHL) for a CIR of 44.4/100,000 py, and 106 cases of ALL/LL for a CIR of 5.1/100,000 py.

Breast cancer survivors had significantly higher incidences, compared with the general population, of AML (standardized incidence ratio [SIR] 2.8, 95% confidence interval [CI], 2.5-3.2), MDS (SIR 5.0, CI, 4.4-5.7), MM (SIR 1.5, CI, 1.3-17), and ALL/LL (SIR 2.0, CI, 1.3-3.0). There was a trend toward significance for both MPN and HL/NHL, but the lower limit of the confidence intervals for these conditions either crossed or touched 1.

In a review of the literature, the authors found that “[s]everal studies linked AML and MDS to chemotherapeutic agents, radiation treatment, and supportive treatment with granulocyte colony-stimulating factor. These results are consistent with other available data showing a 2½-fold to 3½-fold increased risk of AML.”

They noted that their estimate of a five-fold increase in risk for MDS was higher than the 3.7-fold risk reported in a previous registry cohort analysis, suggesting that risk for MDS among breast cancer patients may be underestimated.

“The recent discovery of the gene signatures that guide treatment decisions in early-stage breast cancer might reduce the number of patients exposed to cytotoxic chemotherapy and its complications, including hematologic malignant neoplasm. Therefore, continuing to monitor hematologic malignant neoplasm trends is necessary, especially given that approaches to cancer treatment are rapidly evolving. Further research is also required to assess the modality of treatment for and the genetic predisposition to these secondary malignant neoplasms,” the authors concluded.

SAN DIEGO – A second-generation CD19-specific “armored” chimeric antigen receptor (CAR) T-cell construct was associated with high complete remission rates in diffuse large B-cell lymphoma (DLBCL) and indolent non-Hodgkin lymphoma (NHL) in a phase 1 trial.

Neil Osterweil/ MDedge News

The CAR T construct – labeled 1928z-41BBL – also induced “encouraging” complete remission rates in patients with chronic lymphocytic leukemia (CLL) with Richter’s transformation, reported Jae H. Park, MD, of Memorial Sloan Kettering Cancer Center (MSKCC), New York, and his colleagues.

“Interestingly and encouragingly, severe [cytokine release syndrome] was not seen and grade 3 neurotoxicity was observed in less than 10%, with no grade 4 neurotoxicity, so there appears to be a favorable side effect profile,” Dr. Park said at the annual meeting of the American Society of Hematology.

Just as armored cars are designed to protect their valuable contents from people with bad intent, armored CAR T cells are engineered to protect the modified T-cells from a hostile tumor microenvironment and simultaneously recruit non-modified T cells to the target to produce a more robust immune response against malignant cells.

MSKCC investigators had previously shown that in contrast to other CAR T-cell constructs, the 1928z-41BBL configuration, which consists of two signaling domains (CD28 and CD3zeta) and the 4-1BB ligand, hit the sweet spot between tumor-killing function and T-cell persistence (Cancer Cell. 2015 Oct 12;28[4]:415-28).

In the current study, they enrolled 35 adults with relapsed or refractory CD19-positive hematologic malignancies, 29 of whom eventually underwent CAR T-cell infusions. The treated population comprised 14 patients with CLL (4 of whom had Richter’s transformation), 9 with DLBCL, 5 with indolent NHL, and 1 with acute lymphoblastic leukemia.

The patients with CLL had received a median of 5.5 prior lines of therapy, including ibrutinib (Imbruvica) and venetoclax (Venclexta).

There were 15 complete remissions (CR), with CR rates of 78% in DLBCL, 20% in CLL, 67% in CLL with Richter’s transformation, 60% in patients with indolent NHL, as well as CR in the single patient with ALL.

There were eight partial remissions. One patient with CLL had stable disease, and four patients had disease progression (one patient each with DLBCL, CLL, CLL with Richter’s, and indolent NHL).

Dr. Park noted that T cells are being detected in peripheral blood more than 6 months after T-cell infusion.

There were no cases of severe cytokine release syndrome, defined as requiring vasopressors and/or mechanical ventilation for hypoxia, and just three cases of grade 3 neurotoxicity. There were no cases of grade 4 neurotoxicity, no deaths related to neurotoxicity, and no cases of cerebral edema – a serious complication that has been seen in earlier CAR T-cell studies.

Split or multiple infusions of CAR T cells or incorporation of the technique into earlier lines of therapy might generate higher response rates, Dr. Park said.

The study was supported by Juno Therapeutics. Dr. Park reported consulting for and research funding from Juno, and financial relationships with other companies.

SAN DIEGO – Longer-term follow-up of patients treated with CD19-targeted chimeric antigen receptor (CAR) T cells for hematologic malignancies indicates that the altered cells are generally safe, with most late events being mild in nature and possibly related to therapies delivered before or after CAR T cells, investigators reported.

Among patients treated with CD19-targeted CAR T cells for relapsed or refractory chronic lymphocytic leukemia (CLL) or non-Hodgkin lymphoma (NHL), the most frequent late adverse event was hypogammaglobulinemia, which occurred in 29 of 48 patients evaluated, reported Ana Cordeiro, MD, from the Fred Hutchinson Cancer Research Center in Seattle.

“Our results suggest that CD19 CAR T cells are safe,” Dr. Cordeiro said at the annual meeting of the American Society of Hematology. “However, continuing with prospective systematic and long-term follow-up of these patients is required for better understanding of these late effects.”

Dr. Cordeiro and colleagues studied a total of 60 patients who were enrolled in a phase 1/2 trial at their center of a CD19-targeted CAR T-cell construct and survived for at least 1 year.

The goal of the study was to describe complications that occurred or persisted beyond 90 days after CAR T-cell infusion.

The cohort included 43 patients treated for NHL and 17 treated for CLL. Patients with CLL were followed for a median of 27.5 months, and patients with NHL were followed for a median of 23.8 months.

As of September 2018, 47 patients were still alive, including 15 patients with CLL (88%) and 32 patients with NHL (74%). Of the 17 patients who died, 10 died from progressive disease (2 from CLL and 8 from NHL), and 3 patients died from nonrelapse causes associated with complications from subsequent allogeneic stem cell transplantation (allo-HCT), including 1 patient from graft-versus-host disease (GVHD) and infection, 1 from infection, and 1 from cerberovascular accident/thrombotic microangiopathy.

Of 38 patients who received additional therapies, 17 had subsequent CAR T-cell infusions under the same protocol, and 16 went on to allo-HCT. Treatments for the remaining five patients were not specified.

Of the 22 patients who did not receive additional treatment for their primary malignancies, 21 were in ongoing complete remission following a single CAR T-cell infusion after a median follow-up of 28 months. However, two patients in this group did require treatment for therapy-related myelodysplastic syndrome (t-MDS). The remaining patient had a small CLL clone at last follow-up.

Late adverse events included the following:

• Late significant cytopenias in three of 19 patients evaluated.
• Late hypogammaglobulinemia in 29 of 48 evaluated patients.
• A total of 138 late infections in 31 of the 60 patients.
• Subsequent malignancies in 10 of the 60 patients, including t-MDS, nonmelanoma skin cancer, and noninvasive bladder cancer.
• Late immune-related events in seven patients.
• Late neurogenic/psychiatric events, including one case each of transient ischemic attack at 3.8 months, encephalopathy and myoclonic seizure in the setting of chemotherapy, and a fatal cerebrovascular accident in the setting of allo-HCT and thrombotic microangiopathy. These patients did not have acute neurotoxicity after CAR T-cell therapy, Dr. Cordeiro noted. In addition, three patients experienced exacerbation of depression or anxiety following infusion.
• GVHD in nine patients at a median time from allo-HCT to first CAR T-cell infusion of 46.3 months (range, 6.7 months to 11 years).

Focusing on those patients who achieve complete remissions after CAR T-cell therapy could help investigators isolate late events that are most likely related to CAR T cells, Dr. Cordeiro said.

Dr. Cordeiro reported having no relevant conflicts of interest.

Dr. Cordeiro and colleagues studied a total of 60 patients who were enrolled in a phase 1/2 trial at their center of a CD19-targeted CAR T-cell construct and survived for at least 1 year.

The goal of the study was to describe complications that occurred or persisted beyond 90 days after CAR T-cell infusion.

The cohort included 43 patients treated for NHL and 17 treated for CLL. Patients with CLL were followed for a median of 27.5 months, and patients with NHL were followed for a median of 23.8 months.

As of September 2018, 47 patients were still alive, including 15 patients with CLL (88%) and 32 patients with NHL (74%). Of the 17 patients who died, 10 died from progressive disease (2 from CLL and 8 from NHL), and 3 patients died from nonrelapse causes associated with complications from subsequent allogeneic stem cell transplantation (allo-HCT), including 1 patient from graft-versus-host disease (GVHD) and infection, 1 from infection, and 1 from cerberovascular accident/thrombotic microangiopathy.

Of 38 patients who received additional therapies, 17 had subsequent CAR T-cell infusions under the same protocol, and 16 went on to allo-HCT. Treatments for the remaining five patients were not specified.

Of the 22 patients who did not receive additional treatment for their primary malignancies, 21 were in ongoing complete remission following a single CAR T-cell infusion after a median follow-up of 28 months. However, two patients in this group did require treatment for therapy-related myelodysplastic syndrome (t-MDS). The remaining patient had a small CLL clone at last follow-up.

Late adverse events included the following:

• Late significant cytopenias in three of 19 patients evaluated.
• Late hypogammaglobulinemia in 29 of 48 evaluated patients.
• A total of 138 late infections in 31 of the 60 patients.
• Subsequent malignancies in 10 of the 60 patients, including t-MDS, nonmelanoma skin cancer, and noninvasive bladder cancer.
• Late immune-related events in seven patients.
• Late neurogenic/psychiatric events, including one case each of transient ischemic attack at 3.8 months, encephalopathy and myoclonic seizure in the setting of chemotherapy, and a fatal cerebrovascular accident in the setting of allo-HCT and thrombotic microangiopathy. These patients did not have acute neurotoxicity after CAR T-cell therapy, Dr. Cordeiro noted. In addition, three patients experienced exacerbation of depression or anxiety following infusion.
• GVHD in nine patients at a median time from allo-HCT to first CAR T-cell infusion of 46.3 months (range, 6.7 months to 11 years).

Focusing on those patients who achieve complete remissions after CAR T-cell therapy could help investigators isolate late events that are most likely related to CAR T cells, Dr. Cordeiro said.

Dr. Cordeiro reported having no relevant conflicts of interest.
