The European Society of Cardiology (ESC) has launched a novel position paper, under the auspices of its Committee for Practice Guidelines, on the cardiac toxicity of anticancer therapies.

The paper is a summary and evaluation of relevant scientific evidence that is intended to assist health professionals in selecting the best strategies for preventing and managing cardiac toxicity in patients with cancer, including leukemia, lymphoma, and multiple myeloma.

The paper was published in European Heart Journal and on the ESC website.

The document reviews the potential cardiovascular complications of anticancer therapies.

The complications are divided into 9 categories: myocardial dysfunction and heart failure, coronary artery disease, valvular disease, arrhythmias, arterial hypertension, thromboembolic disease, peripheral vascular disease and stroke, pulmonary hypertension, and pericardial complications.

For each type of complication, the authors outline which patients are at risk and how to detect and prevent the possible side effects. Recommendations are given on how to treat and follow patients who develop that type of cardiotoxicity.

Cardiotoxicity is detected using electrocardiogram, cardiac imaging, and biomarkers. Prevention and treatment may involve the use of cardioprotective drugs (such as angiotensin converting enzyme inhibitors or beta-blockers) and adopting a healthy lifestyle (eating a healthy diet, not smoking, exercising regularly, and controlling body weight).

Regarding long-term surveillance for cancer survivors, the paper says patients should be informed of their increased risk of cardiovascular disease at the outset of cancer treatment and supported to make lifestyle changes. They should be told to report early signs and symptoms of cardiovascular disease promptly.

The paper also emphasizes the importance of establishing multidisciplinary teams to provide the best care for cancer patients and survivors. These should include cardiologists, oncologists, nurses, and heart failure and imaging specialists. Ultimately, cardio-oncology centers with a structured service are needed.

The authors note that under- or over-diagnosis of cardiovascular disease sometimes results in failure to prevent adverse events or inappropriate interruption of a potentially life-saving anticancer treatment.

“We need to be clear when it’s a must to stop the treatment, when we should reduce the dose, or when we can continue with the therapy,” said author Jose Luis Zamorano, MD, of University Hospital Ramón in Madrid, Spain. “This position paper provides guidance in this area.”

“We hope the paper will increase awareness about heart disease in cancer patients and survivors and stimulate more research in this area,” added author Patrizio Lancellotti, MD, PhD, of University of Liège Hospital in Liège, Belgium.

“More information is needed on when to screen and monitor patients and on the cardiovascular effects of new anticancer therapies.”

DURBAN, SOUTH AFRICA – The 15 HIV-infected patients who have undergone allogeneic stem-cell transplant for life-threatening hematologic cancers under the auspices of the European EpiStem Consortium have uniformly demonstrated a profound and durable reduction in viral reservoir to a degree that hasn’t been approached by any other investigational cure strategy, Annemarie Wensing, MD, said at the 21st International AIDS Conference.

“We see an enormous reduction in the viral reservoir, and in two patients we cannot find any viable HIV in the blood using ultrasensitive tests. But we don’t know whether these patients are cured because they are still on antiretroviral therapy,” said Dr. Wensing of Utrecht (The Netherlands) University.

Non-Hodgkin’s lymphoma and Hodgkin’s lymphoma are 7-9 times more frequent in HIV-positive patients than in the general population. But allogeneic stem cell transplantation is an even higher-risk treatment in HIV-positive patients with life-threatening leukemia or lymphoma than in the HIV-negative population. Only 6 of the 15 EuroStem patients remain alive. Eight died within 4 months of the procedure and another died 2.5 years post-transplant, all from progression of their cancer or as a result of opportunistic infections arising during the immunosuppressive chemoablation that’s central to stem-cell transplantation. However, 3 of the 15 patients have survived longer than 3 years. In two of them, no HIV can be detected in blood or intestinal tissue using ultrasensitive tests, while in the third there is “only a slight trace,” according to Dr. Wensing, a clinical virologist.

EpiStem (the European Project to Guide and Investigate the Potential for HIV Cure by Stem-Cell Transplantation) is a multinational collaboration of European oncologists, infectious disease physicians, and other specialists. It was formed in response to the successful outcome of allogeneic stem cell transplantation for acute myeloid leukemia in HIV-positive Timothy Brown, more famously known as “the Berlin patient” (N Engl J Med. 2009 Feb 12;360(7):692-8). He has thus far survived 7 years off antiretroviral therapy.

Much has been made of the fact that Mr. Brown’s donor cells were homozygous for the CCR5 delta32 mutation, which confers natural resistance to HIV infection because it prevents the virus from infecting T cells. Only 1% or less of the population is homozygous for this mutation. But Dr. Wensing isn’t convinced that using donor cells with the mutation is a prerequisite for success. Indeed, while 4 of the 15 EpiStem patients received stem cells from donors homozygous for the mutation and another got donor cells heterozygous for the CCR5 delta32 mutation, the other 10 received stem cells capable of being infected by HIV – yet all 15 experienced an enormous reduction in their viral reservoir. And two of the three patients who have survived longer than 3 years got stem cells without the CCR5 delta32 mutation.

Dr. Wensing observed that a common denominator shared by Timothy Brown and the two EpiStem patients who have trace or undetectable HIV in blood or tissue samples more than 3 years post-transplant is that all three developed severe graft-versus-host disease in conjunction with their stem cell transplantation. She suspects this may have helped them to clear the infection, a hypothesis she intends to pursue further as EpiStem gathers more patients.

Eventually, if patients continue to test negative for HIV using ultrasensitive tests, it will be time to have a discussion with patients and their treating physicians as to whether they should continue on antiretroviral therapy.

“In the end it’s the patients’ decision, but they should be very well counseled because it can have medical and also psychological consequences if HIV returns,” she said.

EpiStem is funded by the American Foundation for AIDS Research Conssortium on HIV Eradication. Dr. Wensing reported having no financial conflicts regarding her presentation.

Daratumumab significantly improved survival when added to the current two-drug regimen for multiple myeloma, according to published data from a phase III study.

Patients treated with the anti-CD38 antibody in addition to the current standard treatment combination of bortezomib and dexamethasone had a 61% progression-free survival rate compared with a 27% rate seen in controls who received only bortezomib and dexamethasone.

The study results were presented initially at the annual meeting of the American Society of Hematology in 2015.

After an average follow-up of 7 months, 67 disease-progression events or deaths occurred in the daratumumab group, compared with 122 in the control group. Overall treatment response rates also were significantly higher in the daratumumab group compared with controls (83% vs. 63%), reported Antonio Palumbo, MD, of the University of Turin, Italy, and his associates in the CASTOR study.

The multicenter, randomized trial included 251 multiple myeloma patients in the daratumumab group 247 patients in the control group. Demographics were similar between the groups; the median patient age was 64 years.

Although more than 95% of patients in each group reported at least one adverse event, fewer than 10% of patients in each group discontinued treatment as a result. The most common adverse events associated with discontinuation were peripheral sensory neuropathy and pneumonia (N Engl J Med 2016;375:754-66).

A study of 2.3 million Jewish subjects suggests that being born in Israel increases a person’s risk of developing Hodgkin lymphoma (HL).

Native Israelis had a higher risk of HL than subjects who immigrated to Israel from Europe, Asia, or North Africa.

Researchers said this finding, published in Leukemia & Lymphoma, suggests that exposure to as-yet-unidentified elements of Israel’s environment increases the risk of HL.

“While we still need further studies to identify the specific causes of the high rates of Hodgkin lymphoma among native Israelis, our findings direct us to search for possible environmental causes in Israel and the neighboring countries,” said study author Hagai Levine, MD, of Hebrew University of Jerusalem in Israel.

“These causes could be not only environmental exposures but also diet, climate, social environment, and stress that may be related to chronic regional conflict.”

Dr Levine and his colleagues noted that the incidence of HL in Israel is among the highest in the world. Based on GLOBOCAN estimates for 2012, Israeli females have the highest age-standardized incidence rate of HL worldwide, and Israeli males have the second highest. From 1960 through 2005, Israel experienced a sharp rise in HL incidence among Israeli-born individuals of both sexes.

Despite evidence for an environmental etiology, very few risk factors have been identified. Studying immigrant populations provides a means of investigating the relative importance of genetic factors as compared to environmental factors in disease development.

With all that in mind, Dr Levine and his colleagues conducted the current study. They included Jewish men and women, ages 16 to 19 at examination, with no history of a cancer diagnosis.

Nationwide data on 2,285,009 adolescents, collected from 1967 through 2011, were linked to Israel’s Cancer Registry to obtain the incidence of HL until 2012.

During 47 million person-years of follow-up, there were 2093 cases of HL detected.

Multivariate analysis suggested native Israelis had a significantly higher risk of developing HL than individuals who immigrated to the country (hazard ratio=1.29, P<0.001). This increased risk was driven largely by an elevated risk for the nodular sclerosis subtype of HL (hazard ratio=1.59, P<0.001).

The researchers noted that the elevated risk appeared within one generation. The low incidence of HL observed for immigrants from Western Asia was no longer evident among Israeli-born individuals of Asian origin. Among immigrants, there was no difference by age at migration.

Therefore, the researchers suggested that immigration from a low-risk to a high-risk location, mostly to locales with a modern lifestyle and environment, is associated with an increase in HL incidence (mainly the nodular sclerosis subtype) within short periods, making genetic drift unlikely as a causal explanation.

On the other hand, the Israeli lifestyle and environment, either independently or by gene-environment interaction, may pose exceptional risks for HL.

“There is increasing evidence for developmental origins of health and disease, with different possible mechanisms, including epigenetic changes or endocrine disruption,” Dr Levine said.

“There is also increasing evidence on the role of prenatal stress in offspring development, including cancer development, especially for hematological malignancies. These data suggest that risk of HL (the nodular sclerosis subtype) is possibly increased due to preconception, prenatal, or early life exposures to a changing lifestyle and environment and its interaction with susceptibility genes.”

Dr Levine and his colleagues also found a higher risk of HL for women, subjects born in more recent years, those with a higher body mass index, and subjects of taller stature.

Micrograph showing CLL

The US Food and Drug Administration (FDA) has granted orphan drug designation to the PI3K delta inhibitor TGR-1202 for the treatment of chronic lymphocytic leukemia (CLL).

The FDA grants orphan designation to drugs and biologics intended to treat, diagnose, or prevent diseases/disorders that affect fewer than 200,000 people in the US.

The designation provides incentives for sponsors to develop products for rare diseases.

This may include tax credits toward the cost of clinical trials, prescription drug user fee waivers, and 7 years of market exclusivity if the drug is approved.

About TGR-1202

TG Therapeutics, Inc. is developing TGR-1202 as a treatment for hematologic malignancies.

The drug is currently being evaluated in the phase 3 UNITY-CLL trial (NCT02612311), which includes patients with previously treated and untreated CLL. Patients are receiving TGR-1202 plus ublituximab, obinutuzumab plus chlorambucil, ublituximab alone, or TGR-1202 alone.

At EHA 2016, researchers reported preliminary results of a phase 1/1b study (NCT02268851) of TGR-1202 in combination with ibrutinib in patients with relapsed/refractory CLL or mantle cell lymphoma.

At ASCO 2016, researchers reported long-term follow-up of 2 studies of TGR-1202.

The first (TGR-1202-101, NCT01767766) is a phase 1 study of TGR-1202 in patients with relapsed or refractory hematologic malignancies.

The second (UTX-TGR-103, NCT02006485) is a phase 1/1b trial evaluating the combination of ublituximab and TGR-1202 in patients with relapsed or refractory non-Hodgkin lymphoma or CLL.

At ASH 2015, researchers reported results of a phase 1 trial (TGR-GA-106, NCT02100852) of TGR-1202 in combination with obinutuzumab and chlorambucil in patients with CLL.

The US Food and Drug Administration (FDA) has granted orphan drug designation to the PI3K delta inhibitor TGR-1202 for the treatment of chronic lymphocytic leukemia (CLL).

The FDA grants orphan designation to drugs and biologics intended to treat, diagnose, or prevent diseases/disorders that affect fewer than 200,000 people in the US.

The designation provides incentives for sponsors to develop products for rare diseases.

This may include tax credits toward the cost of clinical trials, prescription drug user fee waivers, and 7 years of market exclusivity if the drug is approved.

Massage therapy can reduce pain, fatigue, and anxiety in cancer patients, according to a review and meta-analysis published in Pain Medicine.

Massage therapy is commonly used among people seeking pain management, and research has generally supported its use.

However, there has been no published, rigorous review of the available research and evidence for massage therapy’s efficacy for pain populations, especially for cancer populations.

So Courtney Boyd, of the Samueli Institute in Alexandria, Virginia, and her colleagues set out to conduct just such a review.

The team assessed the quality of massage therapy research and evidence for its efficacy in treating pain, function-related quality of life, and health-related quality of life in cancer patients.

The researchers reviewed data from 12 high-quality studies and 4 low-quality studies.

The team said they could not assess health-related quality of life, emotional stress, or activity outcomes because too few of the studies examined these outcomes.

However, the data suggested that massage therapy can effectively reduce pain intensity or severity when compared to no treatment (standardized mean difference [SMD]=-0.20) or active comparators (SMD=-0.55).

Massage therapy also proved effective for reducing fatigue (SMD=-1.06) and anxiety (SMD=-1.24) when compared to active comparators.

Based on these results, the researchers concluded that massage therapy may have beneficial effects in cancer patients, so they should consider it as an option.

However, before definitive clinical conclusions and recommendations can be made at a policy level, specific factors surrounding the massage protocol, as well as selection of appropriate controls and standard outcomes, need to be well-understood.

Dendritic cells in skin

The US Food and Drug Administration (FDA) has granted breakthrough therapy designation for SL-401 in the treatment of blastic plasmacytoid dendritic cell neoplasm (BPDCN).

SL-401 is a targeted therapy directed to the interleukin-3 receptor (IL-3R), which is present in BPDCN and other hematologic malignancies.

SL-401 is composed of human IL-3 coupled to a truncated diphtheria toxin payload that inhibits protein synthesis.

The drug is under development by Stemline Therapeutics, Inc.

About breakthrough designation

The FDA’s breakthrough designation is intended to expedite the development and review of new therapies for serious or life-threatening conditions.

To earn the designation, a treatment must show encouraging early clinical results demonstrating substantial improvement over available therapies with regard to a clinically significant endpoint, or it must fulfill an unmet need.

Phase 2 trial of SL-401

The breakthrough designation for SL-401 was supported by data from a phase 2 trial of patients with BPDCN or acute myeloid leukemia. Results observed in the BPDCN patients were presented at the 2016 EHA Congress (abstract S812).

The study consists of a lead-in dose-escalation stage (stage 1) and subsequent expansion stage (stage 2). In stage 1, patients received SL-401 as a daily intravenous infusion for up to 5 days (7, 9, 12, or 16 μg/kg/day) every 21 days. In stage 2, patients received SL-401 at the optimal stage 1 dose—12 μg/kg.

At the data cut-off, 18 BPDCN patients had received SL-401 at 7 μg/kg (n=3, stage 1) or 12 μg/kg (n=15, 6 in stage 1, 9 in stage 2).

Fifteen of these patients were evaluable for response. The overall response rate was 87% (13/15). All 10 previously untreated BPDCN patients achieved a response, including 7 complete responses (CRs).

All 8 previously untreated BPDCN patients treated at the optimal dose (12 μg/kg) achieved a response, including 6 CRs. Four of these patients were still on SL-401 and in CR at the data cutoff, and 2 had gone on to stem cell transplant.

The most common treatment-related adverse events in the BPDCN patients were transient transaminase elevation (57%), hypoalbuminemia (40%), and transient thrombocytopenia (15%).

In stage 1, two patients had capillary leak syndrome (CLS)—one grade 5 (7 μg/kg) and one grade 4 (12 μg/kg). After this, safety precautions were implemented to minimize the risk of severe CLS. There have been no cases of severe CLS since then.

Prescription medications

High prescription drug prices in the US have a few causes, according to researchers.

They said causes include the approach the US has taken to granting government-protected monopolies to drug manufacturers, strategies that delay access to generic drugs, and the restriction of price negotiation at a level not observed in other industrialized nations.

The researchers outlined these issues in JAMA.

Aaron S. Kesselheim, MD, of Brigham and Women’s Hospital in Boston, Massachusetts, and his colleagues conducted this research.

The team reviewed the medical and health policy literature from January 2005 to July 2016, looking for articles addressing the sources of drug prices in the US, the justifications and consequences of high prices, and possible solutions.

The researchers found that per-capita prescription drug spending is higher in the US than in all other countries. In 2013, per-capita spending on prescription drugs was $858 in the US, compared with an average of $400 for 19 other industrialized nations.

Dr Kesselheim and his colleagues said prescription drug spending in the US is largely driven by brand-name drug prices that have been increasing in recent years. And drug prices are higher in the US because the US healthcare system allows manufacturers to set their own price for a given product.

In countries with national health insurance systems, on the other hand, a delegated body negotiates drug prices or rejects coverage of products if the price demanded by the manufacturer is excessive in light of the benefit provided. Manufacturers may then decide to offer the drug at a lower price.

The researchers said the most important factor that allows US manufacturers to set high drug prices is market exclusivity. And although cheaper generic drugs can be made available after an exclusivity period has passed, there are strategies for keeping these drugs off the market.

Furthermore, the negotiating power of the payer is constrained by several factors, including the requirement that most government drug payment plans cover nearly all products.

Considering these findings together, Dr Kesselheim and his colleagues said the most realistic short-term strategies to address high drug prices in the US include:

• Enforcing more stringent requirements for market exclusivity rights
• Ensuring timely generic drug availability
• Providing greater opportunities for price negotiation by governmental payers
• Generating more evidence about comparative cost-effectiveness of therapeutic alternatives
• Educating patients, prescribers, payers, and policy makers about these choices.

The researchers said there is little evidence that such policies would hamper innovation. In fact, they might even drive the development of more valuable new therapies rather than rewarding the persistence of older ones.

The use of mogamulizumab before allogeneic hematopoietic stem-cell transplantation in aggressive adult T-cell leukemia/lymphoma is associated with an increased risk of acute graft-versus-host disease (GVHD), which leads to an inferior overall survival, investigators report in the Journal of Clinical Oncology.

Mogamulizumab is an anti-CCR4 monoclonal antibody that showed promise in small clinical studies when added to conventional chemotherapy as first-line treatment. It was recently approved for the treatment of adult T-cell leukemia/lymphoma in Japan, and eventually may be approved in the U.S. and other countries, said Shigeo Fuji, MD, of the department of hematopoietic stem-cell transplantation, National Cancer Center Hospital, Tokyo, and his associates.

The agent significantly depleted regulatory T cells for several months in animal models. This prompted concern regarding the possibility of exacerbating GVHD in human patients who don’t respond completely to first-line chemotherapy and then undergo stem-cell transplantation. “However, no direct evidence has demonstrated [regulatory T-cell] depletion in humans,” the investigators noted.

To examine this issue, they assessed clinical outcomes in a cohort of 996 patients across Japan who had aggressive adult T-cell leukemia/lymphoma, were aged 20-69 years, were diagnosed in 2000-2013, and received intensive, multiagent chemotherapy before undergoing allogeneic hematopoietic stem-cell transplantation.

Grade 2-4 acute GVHD developed in 381 of 873 patients who didn’t receive mogamulizumab (43.6%), compared with 47 of 81 patients who did receive the agent (58.0%), for a relative risk of 1.33 (P = .01). Grade 3-4 acute GVHD developed in 150 patients who didn’t receive mogamulizumab (17.2%), compared with 25 who did (30.9%), for an RR of 1.80 (P less than .01) .

The agent not only raised the rate of GVHD, it also increased the severity of the disorder. GVHD was refractory to systemic corticosteroids in 23.5% of patients who didn’t receive mogamulizumab, compared with 48.9% of those who did, for an RR of 2.09 (P less than .01), the investigators reported (J Clin Oncol. 2016. doi: 10.1200/JCO.2016.67.8250).

In addition, 1-year disease-free mortality was 25.1% without mogamulizumab, compared with 43.7% with it. The estimated 1-year overall survival was 49.4% without mogamulizumab, compared with 32.3% with it. And in multivariable analyses, receiving mogamulizumab before undergoing stem-cell transplantation was a significant risk factor for both disease-free mortality (hazard ratio, 1.93) and overall mortality (HR, 1.67).

“All hematologists should take the risks and benefits of mogamulizumab into consideration before they use [it] in transplantation-eligible patients,” Dr. Fuji and his associates said.

Grade 3-4 acute GVHD developed in 150 patients who didn’t receive mogamulizumab (17.2%), compared with 25 who did (30.9%), for an RR of 1.80 (P less than .01) .

The agent not only raised the rate of GVHD, it also increased the severity of the disorder. GVHD was refractory to systemic corticosteroids in 23.5% of patients who didn’t receive mogamulizumab, compared with 48.9% of those who did, for an RR of 2.09 (P less than .01), the investigators reported (J Clin Oncol. 2016. doi: 10.1200/JCO.2016.67.8250).

In addition, 1-year disease-free mortality was 25.1% without mogamulizumab, compared with 43.7% with it. The estimated 1-year overall survival was 49.4% without mogamulizumab, compared with 32.3% with it. And in multivariable analyses, receiving mogamulizumab before undergoing stem-cell transplantation was a significant risk factor for both disease-free mortality (hazard ratio, 1.93) and overall mortality (HR, 1.67).

“All hematologists should take the risks and benefits of mogamulizumab into consideration before they use [it] in transplantation-eligible patients,” Dr. Fuji and his associates said.
