Results of a small, single-center study suggest oncologists may not provide cancer patients with adequate guidance on exercise.

A majority of the patients and oncologists surveyed for this study placed importance on exercise during cancer care, but most of the oncologists failed to give patients recommendations on exercise.

“Our results indicate that exercise is perceived as important to patients with cancer, both from a patient and physician perspective,” said study author Agnes Smaradottir, MD, of Gundersen Health System in La Crosse, Wisconsin.

“However, physicians are reluctant to consistently include [physical activity] recommendations in their patient discussions.”

Dr Smaradottir and her colleagues reported these findings in JNCCN.

The researchers surveyed 20 cancer patients and 9 oncologists for this study.

The patients’ mean age was 64. Ten patients had stage I-III non-metastatic cancer after adjuvant therapy, and 10 had stage IV metastatic disease and were undergoing palliative treatment. Most patients had solid tumor malignancies, but 1 had chronic lymphocytic leukemia.

The oncologists’ mean age was 45, 56% were male, and they had a mean of 12 years of practice. Most (89%) said they exercise on a regular basis.

Discussions

Nineteen (95%) of the patients surveyed felt they benefited from exercise during treatment, but only 3 of the patients recalled being instructed to exercise.

Exercise was felt to be an equally important part of treatment and well-being for patients with early stage cancer treated with curative intent as well as patients receiving palliative therapy.

Although all the oncologists noted that exercise can benefit cancer patients, only 1 of the 9 surveyed documented discussion of exercise in patient charts.

Preferences and concerns

More than 80% of the patients said they would prefer a home-based exercise regimen that could be performed in alignment with their personal schedules and symptoms.

Patients also noted a preference that exercise recommendations come from their oncologists, as they have an established relationship and feel their oncologists best understand the complexities of their personalized treatment plans.

The oncologists, on the other hand, wanted to refer patients to specialist care for exercise recommendations. Reasons for this included the oncologists’ mounting clinic schedules and a lack of education about appropriate physical activity recommendations for patients.

The oncologists also expressed concern about asking patients to be more physically active during chemotherapy and radiation and expressed trepidation about prescribing exercise to frail patients with limited mobility.

“We were surprised by the gap in expectations regarding exercise recommendation between patients and providers,” Dr Smaradottir said. “Many providers, ourselves included, thought patients would prefer to be referred to an exercise center, but they clearly preferred to have a home-based program recommended by their oncologist.”

“Our findings highlight the value of examining both patient and provider attitudes and behavioral intentions. While we uncovered barriers to exercise recommendations, questions remain on how to bridge the gap between patient and provider preferences.”

VIENNA, AUSTRIA—Children with cancer may not require general anesthesia prior to radiotherapy if they can watch videos during their treatment, according to research presented at the ESTRO 36 conference (abstract OC-0546).

Allowing children to watch videos during radiotherapy reduced but did not completely eliminate the use of anesthesia in this small study.

The use of videos proved less traumatic than anesthesia for children and their families, as well as making each treatment quicker and more cost-effective, according to study investigator Catia Aguas, of the Cliniques Universitaires Saint Luc in Brussels, Belgium.

“Being treated with radiotherapy means coming in for a treatment every weekday for 4 to 6 weeks,” Aguas noted. “The children need to remain motionless during treatment, and, on the whole, that means a general anesthesia. That, in turn, means they have to keep their stomach empty for 6 hours before the treatment.”

“We wanted to see if installing a projector and letting children watch a video of their choice would allow them to keep still enough that we would not need to give them anesthesia.”

The study included 12 children, ages 1.5 to 6 years, who were treated with radiotherapy using a Tomotherapy® treatment unit at the university hospital. Six children were treated before a video projector was installed in 2014, and 6 were treated after.

Before the video was available, general anesthesia was needed for 83.3% of children’s treatments. Once the projector was installed, anesthesia was needed in 33.3% of treatments.

“Radiotherapy can be very scary for children,” Aguas noted. “It’s a huge room full of machines and strange noises, and the worst part is that they’re in the room alone during their treatment. Before their radiotherapy treatment, they have already been through a series of tests and treatments, some of them painful, so when they arrive for radiotherapy, they don’t really feel very safe or confident.”

“Since we started using videos, children are a lot less anxious. Now they know that they’re going to watch a movie of their choice, they’re more relaxed, and, once the movie starts, it’s as though they travel to another world. Sponge Bob, Cars, and Barbie have been popular movie choices with our patients.”

The research also showed that treatments that used to take 1 hour or more now take around 15 to 20 minutes. This is partly because of the time saved by not having to prepare and administer anesthesia, but it is also because the children who know they are going to watch videos are more cooperative.

“Now, in our clinic, video has almost completely replaced anesthesia, resulting in reduced treatment times and reduction of stress for the young patients and their families,” Aguas said.

She also noted that the projector was inexpensive and simple to install.

“In radiotherapy, everything is usually very expensive, but, in this case, it was not,” Aguas said. “We bought a projector, and, with the help of college students, we created a support to fix the device to the patient couch. Using video is saving money and resources by reducing the need for anesthesia.”

Aguas and her colleagues continue to study children who have been treated since the projector was installed, and the team is extending the project to include adult patients who are claustrophobic or anxious.

VIENNA, AUSTRIA—Hodgkin lymphoma (HL) survivors who received chest irradiation should be screened for coronary artery disease (CAD), according to researchers.

The team evaluated HL survivors who underwent mediastinal irradiation 20 years prior to study initiation.

These individuals were more likely to have CAD and to have more severe CAD than matched control subjects.

The researchers presented these findings at ICNC 2017, the International Conference on Nuclear Cardiology and Cardiac CT (abstract P118).

“Patients with Hodgkin lymphoma receive high-dose mediastinal irradiation at a young age as part of their treatment,” said Alexander van Rosendael, MD, of Leiden University Medical Centre in the Netherlands.

“There is an ongoing debate about whether to screen patients who get chest irradiation for coronary artery disease.”

Therefore, Dr van Rosendael and his colleagues assessed the extent, severity, and location of CAD in HL survivors who had received chest irradiation.

The study included 79 patients who had been free of HL for at least 10 years and had received mediastinal irradiation 20 years ago, plus 273 control subjects without HL or irradiation.

CAD was assessed using coronary computed tomography angiography (CTA). To assess differences in CAD between patients and controls, they were matched in a 1:3 fashion by age, gender, diabetes, hypertension, hypercholesterolemia, family history of CAD, and smoking status.

Patients were 45 years old, on average, and the presence of cardiovascular risk factors was low overall.

Forty-two percent of patients had no atherosclerosis on coronary CTA, compared to 64% of controls (P<0.001).

Regarding the extent and severity of CAD, HL patients had significantly more multi-vessel CAD than controls. Ten percent of patients had 2-vessel disease, and 24% had 3-vessel disease, compared to 6% and 9% of controls, respectively (P=0.001).

The segment involvement score (which measures overall coronary plaque distribution) and the segment stenosis score (which measures overall coronary plaque extent and severity) were significantly higher for patients than for controls (P<0.001 and P=0.034, respectively).

Regarding the location of CAD, patients had significantly more coronary plaques in the left main (17% vs 6%, P=0.004), proximal left anterior descending (30% vs 16%, P=0.004), proximal right coronary artery (25% vs 10%, P<0.001), and proximal left circumflex (14% vs 6%, P=0.022), but not in non-proximal coronary segments.

Patients had about a 4-fold higher risk of proximal plaque and about 3-fold higher risk of proximal obstructive stenosis compared to controls (odds ratios, 4.1 and 2.9, respectively; P values, <0.001 and 0.025, respectively).

“Hodgkin patients who have chest irradiation have much more CAD than people of the same age who did not have irradiation,” Dr van Rosendael said.

“The CAD occurred at a young age—patients were 45 years old, on average—and was probably caused by the irradiation. The CTA was done about 20 years after chest irradiation, so there was time for CAD to develop.”

“What was remarkable was that irradiated patients had all the features of high-risk CAD, including high stenosis severity, proximal location, and extensive disease. We know that the proximal location of the disease is much riskier, and this may explain why Hodgkin patients have such poor cardiovascular outcomes when they get older.”

Dr van Rosendael explained that irradiation of the chest can cause inflammation of the coronary arteries, making patients more vulnerable to developing CAD. But it is not known why the CAD in irradiated patients tends to be proximally located.

He said the finding of more, and more severe, CAD in irradiated patients supports the argument for screening.

“When you see CAD in patients who received chest irradiation, it is high-risk CAD,” he said. “Such patients should be screened at regular intervals after irradiation so that CAD can be spotted early and early treatment can be initiated.”

“These patients are around 45 years old, and they are almost all asymptomatic. If you see a severe left main stenosis by screening with CTA (which occurred in 4%), then you can start statin therapy and perform revascularization, which may improve outcome. We know such treatment reduces the risk of events in non-irradiated patients, so it seems likely that it would benefit Hodgkin patients.”

Efficacy and safety profiles were similar for subcutaneous and standard IV rituximab when given as first-line therapy to adults with follicular lymphoma, based on results of a phase III clinical trial published online in Lancet Haematology.

Administering rituximab by IV infusion can take up to 6 hours to complete and requires continuous monitoring. Subcutaneous delivery takes approximately 6 minutes using a new rituximab formulation that is 12 times more concentrated to reduce the administered volume. The new formulation is expected to reduce the burden of treatment for patients, as well as for the health care system, said Andrew Davies, PhD, of the Cancer Research UK Centre, Southampton, and his associates.

They compared the two agents in an international open-label trial funded by Hoffmann-La Roche, maker of the subcutaneous formulation. Adult patients at 113 medical centers in 30 countries were randomly assigned to receive either IV (205 patients) or subcutaneous (205 patients) rituximab during induction therapy with six to eight cycles of CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) or CVP (cyclophosphamide, vincristine, and prednisone). They continued with rituximab as maintenance therapy every 2 months for 2 years. The median duration of treatment was 27 months, and median follow-up was 37 months.

The primary efficacy end point – overall (complete or partial) response rate at the end of induction, based on investigator assessment confirmed by an independent review panel of radiologists – was 84.9% with IV and 84.4% with subcutaneous rituximab, a nonsignificant difference. Similarly, the overall response rate at the end of maintenance therapy was not significantly different between the two groups, at 78.1% and 77.9%, respectively.

Progression-free survival (hazard ratio, 0.84) and event-free survival (HR, 0.91) also did not differ significantly between the two study groups, the investigators said (Lancet Haematol. 2017 doi: 10.1016/S2352.3026(17)30078-9).

The rates of adverse events, grade 3 or higher adverse events, and serious adverse events also were similar for IV and subcutaneous formulations of rituximab. “Administration-related reactions were more common in the subcutaneous group but were predominantly mild-to-moderate local injection-site reactions, such as mild pain, swelling and erythema, reflecting the expected change in safety profile when switching to the subcutaneous route of administration,” Dr. Davies and his associates said.

These results indicate that subcutaneous administration of rituximab along with chemotherapy doesn’t compromise the agent’s antilymphoma activity, they added.

Similarly, the overall response rate at the end of maintenance therapy was not significantly different between the two groups, at 78.1% and 77.9%, respectively.

Progression-free survival (hazard ratio, 0.84) and event-free survival (HR, 0.91) also did not differ significantly between the two study groups, the investigators said (Lancet Haematol. 2017 doi: 10.1016/S2352.3026(17)30078-9).

The rates of adverse events, grade 3 or higher adverse events, and serious adverse events also were similar for IV and subcutaneous formulations of rituximab. “Administration-related reactions were more common in the subcutaneous group but were predominantly mild-to-moderate local injection-site reactions, such as mild pain, swelling and erythema, reflecting the expected change in safety profile when switching to the subcutaneous route of administration,” Dr. Davies and his associates said.

These results indicate that subcutaneous administration of rituximab along with chemotherapy doesn’t compromise the agent’s antilymphoma activity, they added.

Efficacy and safety profiles were similar for subcutaneous and standard IV rituximab when given as first-line therapy to adults with follicular lymphoma, based on results of a phase III clinical trial published online in Lancet Haematology.

Administering rituximab by IV infusion can take up to 6 hours to complete and requires continuous monitoring. Subcutaneous delivery takes approximately 6 minutes using a new rituximab formulation that is 12 times more concentrated to reduce the administered volume. The new formulation is expected to reduce the burden of treatment for patients, as well as for the health care system, said Andrew Davies, PhD, of the Cancer Research UK Centre, Southampton, and his associates.

They compared the two agents in an international open-label trial funded by Hoffmann-La Roche, maker of the subcutaneous formulation. Adult patients at 113 medical centers in 30 countries were randomly assigned to receive either IV (205 patients) or subcutaneous (205 patients) rituximab during induction therapy with six to eight cycles of CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) or CVP (cyclophosphamide, vincristine, and prednisone). They continued with rituximab as maintenance therapy every 2 months for 2 years. The median duration of treatment was 27 months, and median follow-up was 37 months.

The primary efficacy end point – overall (complete or partial) response rate at the end of induction, based on investigator assessment confirmed by an independent review panel of radiologists – was 84.9% with IV and 84.4% with subcutaneous rituximab, a nonsignificant difference. Similarly, the overall response rate at the end of maintenance therapy was not significantly different between the two groups, at 78.1% and 77.9%, respectively.

Progression-free survival (hazard ratio, 0.84) and event-free survival (HR, 0.91) also did not differ significantly between the two study groups, the investigators said (Lancet Haematol. 2017 doi: 10.1016/S2352.3026(17)30078-9).

BOSTON—A pair of preclinical studies suggest the FLT3/BTK inhibitor CG’806 is active in a range of hematologic malignancies.

In one of the studies, CG’806 proved particularly effective against acute myeloid leukemia (AML) cells harboring mutant forms of FLT3, and the compound was able to eradicate AML in mice.

In another study, researchers found CG’806 exhibited “broad potency” against leukemias, lymphomas, myelodysplastic syndromes (MDS), and myeloproliferative neoplasms (MPNs).

Both studies were presented as posters at Hematologic Malignancies: Translating Discoveries to Novel Therapies (poster 25 and poster 44).

Both studies involved researchers from Aptose Biosciences, the company developing CG’806.

Poster 25

Weiguo Zhang, MD, PhD, of The University of Texas MD Anderson Cancer Center in Houston, and his colleagues presented poster 25, “CG’806, a first-in-class FLT3/BTK inhibitor, exerts superior potency against AML cells harboring ITD, TKD and gatekeeper mutated FLT3 or wild-type FLT3.”

The researchers tested CG’806 and other FLT3 inhibitors in human or murine leukemia cell lines with wild-type (WT) FLT3, FLT3-ITD mutations, FLT3 TKD domain mutations, or ITD plus TKD mutations.

Compared to second-generation FLT3 inhibitors (quizartinib, gilteritinib, or crenolanib), CG’806 showed more pronounced anti-proliferative effects in leukemia cells with ITD mutations, D835 mutations, ITD plus F691I/Y842D/D835 mutations, or in FLT3 WT cells.

With CG’086, the IC50s in human AML cell lines were 0.17 nM for MV4-11 (FLT3-ITD) and 0.82 nM for MOLM13 (FLT3-ITD).

The IC50s in the murine leukemia cell lines were 9.49 nM for Ba/F3 (FLT3-WT), 0.30 nM for Ba/F3 (FLT3-ITD), 8.26 nM for Ba/F3 (FLT3-D835Y), 9.72 nM for Ba/F3 (FLT3-ITD+D835Y), and 0.43 nM for Ba/F3 (FLT3-ITD+F691L).

The researchers also found that CG’806 “triggers marked apoptosis” in FLT3-ITD-mutated primary AML samples but minimal apoptosis in normal bone marrow cells.

Another finding was that once-daily oral dosing of CG’806 in a murine model of AML (MV4-11) resulted in sustained micromolar plasma concentration over a 24-hour period.

This was accompanied by complete elimination of AML FLT3-ITD tumors without toxicity, the researchers said.

Poster 44

Stephen E. Kurtz, PhD, of Oregon Health & Science University in Portland, and his colleagues presented poster 44, “CG’806, a First-in-Class FLT3/BTK Inhibitor, Exhibits Potent Activity against AML Patient Samples with Mutant or Wild-Type FLT3, as well as Other Hematologic Malignancy Subtypes.”

The researchers tested CG’806 in samples from patients with AML (n=82), MDS/MPNs (n=15), acute lymphoblastic leukemia (ALL, n=17), chronic lymphocytic leukemia (CLL, n=58), and chronic myeloid leukemia (CML, n=4).

The team observed “broad sensitivity” to CG’806, with 59% (48/82) of AML, 53% (8/15) of MDS/MPN, 40% (23/58) of CLL, 29% (5/17) of ALL, and 25% (1/4) of CML cases exhibiting an IC50 of less than 100 nM.

Among the 38 tested AML samples with known FLT3 mutational status, the FLT3-ITD+ AML samples tended to have enhanced sensitivity to CG’806 (median IC50 = 20 nM, n=8) relative to the FLT3-WT samples (median IC50 = 120 nM, n=30).

The researchers also found that CG’806 exerted potent anti-proliferative activity against human AML, B-ALL, mantle cell lymphoma, Burkitt lymphoma, and diffuse large B-cell lymphoma cell lines.

“The analyses of CG’806 against primary hematologic malignancy patient samples and cultured cell lines show evidence of potent and broad drug activity in AML and other disease subtypes and support further development of this agent for hematologic malignancies,” Dr Kurtz said.

In a phase 3 trial, subcutaneous (SC) and intravenous (IV) rituximab produced comparable results as part of a first-line treatment regimen for follicular lymphoma (FL).

Overall response rates (ORR) were similar in patients who received SC rituximab and those who received IV rituximab, first in combination with chemotherapy and then alone as maintenance therapy.

Although patients who received SC rituximab had administration-related reactions that weren’t observed in the IV rituximab group, these events were largely mild-to-moderate local injection-site reactions.

Andrew Davies, PhD, of the University of Southampton in the UK, and his colleagues reported these results in The Lancet Haematology.

Data from stage 1 of this study, known as SABRINA, were previously published in The Lancet Oncology. The current publication includes stage 2 data.

The study was funded by Roche, which markets rituximab as Rituxan and MabThera.

The trial enrolled 410 patients with previously untreated, grade 1-3a, CD20-positive FL.

Patients were randomized to receive IV rituximab at 375 mg/m² (n=205) or SC rituximab at 1400 mg (n=205) plus chemotherapy.

Chemotherapy consisted of 6 to 8 cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or 8 cycles of cyclophosphamide, vincristine, and prednisone (CVP) every 3 weeks during induction.

Patients then received rituximab maintenance every 8 weeks.

The researchers said baseline characteristics were balanced between the treatment arms, although there were more females in the SC arm than the IV arm—120 (59%) and 99 (48%), respectively.

Efficacy

In stage 1 of this study, the primary endpoint was the ratio of observed rituximab serum trough concentrations (C_trough) between the treatment arms at cycle 7.

The results suggested SC rituximab was non-inferior to the IV formulation. The geometric mean C_trough was 83.13 μg/mL in the IV arm and 134.58 μg/mL in the SC arm (ratio=1.62).

In stage 2, the primary endpoint was efficacy, or ORR, at the end of induction based on the researchers’ assessments and confirmed by an independent review panel of radiologists.

At the end of induction, the ORR was 84.9% (174/205) in the IV arm and 84.4% (173/205) in the SC arm. The complete response rate was 32.2% (n=66) in both arms.

At the end of maintenance therapy, the ORR was 78.1% (139/178) in the IV arm and 77.9% (134/172) in the SC arm. The complete response rates were 56.2% (n=100) and 50.6% (n=87), respectively.

At a median follow-up of 37 months, there was no significant difference between the arms with regard to progression-free survival (hazard ratio[HR]=0.84), event-free survival (HR=0.91), or overall survival (HR=0.81).

Safety

The incidence of adverse events (AEs) was similar between the treatment arms—95% in the IV arm and 96% in the SC arm. The incidence of grade 3 or higher AEs was 55% and 56%, respectively, and the incidence of serious AEs was 34% and 37%, respectively.

Overall, the most common AEs were gastrointestinal disorders (60% in the IV arm and 66% in the SC arm), infections and infestations (64% and 67%, respectively), and general or administration site conditions (50% and 60%, respectively).

Administration-related reactions were more common in the SC arm than the IV arm—48% and 35%, respectively. The most common of these reactions were chills (7%) and pruritus (6%) in the IV arm and injection-site erythema (11%), pruritus (6%), rash (5%), and injection-site pain (5%) in the SC arm.

Neutropenia was the most common grade 3 or higher AE, occurring in 34% of patients in the IV arm and 37% in the SC arm. Febrile neutropenia was the most frequent serious AE, occurring in 5% and 6%, respectively.

The researchers said these results suggest the SC formulation of rituximab has similar efficacy and a similar safety profile as IV rituximab in the first-line treatment of FL.

The European Commission (EC) has approved the anti-PD-1 therapy pembrolizumab (Keytruda) for use in patients with classical Hodgkin lymphoma (cHL).

The drug is now approved to treat adults with relapsed or refractory cHL who have failed autologous stem cell transplant (auto-SCT) and brentuximab vedotin (BV) or who are transplant-ineligible and have failed treatment with BV.

The approval allows marketing of pembrolizumab for this indication in the European Economic Area (EEA).

This is the first approval for pembrolizumab in a hematologic malignancy in the EEA. The drug was previously approved there as a treatment for melanoma and non-small-cell lung cancer.

The new approval for pembrolizumab was based on data from the KEYNOTE-087 and KEYNOTE-013 trials.

Results from KEYNOTE-013 were presented at the 2016 ASH Annual Meeting (abstract 1108), and results from KEYNOTE-087 were recently published in the Journal of Clinical Oncology.

KEYNOTE-087

In this phase 2 trial, researchers evaluated pembrolizumab (a 200 mg fixed dose every 3 weeks) in patients with relapsed or refractory cHL across 3 cohorts:

• Cohort 1: Patients who progressed after auto-HSCT and subsequent treatment with BV
• Cohort 2: Patients who failed salvage chemotherapy, were ineligible for a transplant, and progressed after BV
• Cohort 3: Patients who progressed after auto-HSCT and did not receive BV after transplant.

Across all 210 enrolled patients, the overall response rate (ORR) was 69.0%, and the complete response (CR) rate was 22.4%.

In Cohort 1 (n=69), the ORR was 73.9%, and the CR rate was 21.7%.

In Cohort 2 (n=81), the ORR was 64.2%, and the CR rate was 24.7%.

In Cohort 3 (n=60), the ORR was 70.0%, and the CR rate was 20%.

For the entire study cohort, the median duration of response was not reached, and the median overall survival (OS) was not reached. At 9 months, the OS was 97.5%, and the progression-free survival (PFS) was 63.4%.

The most common grade 3/4 treatment-related AEs were neutropenia (2.4%), diarrhea (1.0%), and dyspnea (1.0%). Immune-mediated AEs included pneumonitis (2.9%), hyperthyroidism (2.9%), colitis (1.0%), and myositis (1.0%).

There were 9 discontinuations because of treatment-related AEs and no treatment-related deaths.

KEYNOTE-013

KEYNOTE-013 is a phase 1b trial that has enrolled 31 patients with relapsed or refractory cHL who failed auto-HSCT and subsequent BV or who were transplant-ineligible.

Patients received pembrolizumab at 10 mg/kg every 2 weeks. The median duration of follow-up was 29 months.

The ORR was 58%, and the CR rate was 19%. The median duration of response had not been reached at last follow-up (range, 0.0+ to 26.1+ months), and 70% of responding patients had a response lasting 12 months or more.

The median PFS was 11.4 months (range, 4.9-27.8 months). The 6-month PFS rate was 66%, and the 12-month PFS rate was 48%.

The median OS was not reached. Six-month and 12-month OS rates were 100% and 87%, respectively.

The most common treatment-related AEs were diarrhea (19%), hypothyroidism (13%), pneumonitis (13%), nausea (13%), fatigue (10%), and dyspnea (10%).

The most common grade 3/4 treatment-related AEs were colitis (3%), axillary pain (3%), AST increase (3%), joint swelling (3%), nephrotic syndrome back pain (3%), and dyspnea (3%).

AEs leading to discontinuation were nephrotic syndrome (grade 3), interstitial lung disease (grade 2), and pneumonitis (grade 2). There were no treatment-related deaths.

The European Commission (EC) has approved the anti-PD-1 therapy pembrolizumab (Keytruda) for use in patients with classical Hodgkin lymphoma (cHL).

The drug is now approved to treat adults with relapsed or refractory cHL who have failed autologous stem cell transplant (auto-SCT) and brentuximab vedotin (BV) or who are transplant-ineligible and have failed treatment with BV.

The approval allows marketing of pembrolizumab for this indication in the European Economic Area (EEA).

This is the first approval for pembrolizumab in a hematologic malignancy in the EEA. The drug was previously approved there as a treatment for melanoma and non-small-cell lung cancer.

The new approval for pembrolizumab was based on data from the KEYNOTE-087 and KEYNOTE-013 trials.

Results from KEYNOTE-013 were presented at the 2016 ASH Annual Meeting (abstract 1108), and results from KEYNOTE-087 were recently published in the Journal of Clinical Oncology.

KEYNOTE-087

In this phase 2 trial, researchers evaluated pembrolizumab (a 200 mg fixed dose every 3 weeks) in patients with relapsed or refractory cHL across 3 cohorts:

• Cohort 1: Patients who progressed after auto-HSCT and subsequent treatment with BV
• Cohort 2: Patients who failed salvage chemotherapy, were ineligible for a transplant, and progressed after BV
• Cohort 3: Patients who progressed after auto-HSCT and did not receive BV after transplant.

Across all 210 enrolled patients, the overall response rate (ORR) was 69.0%, and the complete response (CR) rate was 22.4%.

In Cohort 1 (n=69), the ORR was 73.9%, and the CR rate was 21.7%.

In Cohort 2 (n=81), the ORR was 64.2%, and the CR rate was 24.7%.

In Cohort 3 (n=60), the ORR was 70.0%, and the CR rate was 20%.

Long-term follow-up of a phase 1 study suggests the BTK inhibitor ONO/GS-4059 can stave off progression in patients with relapsed or refractory chronic lymphocytic leukemia (CLL).

Roughly 60% of the patients studied were progression-free and still taking ONO/GS-4059 at last follow-up, with the longest time on treatment exceeding 3 years.

In addition, researchers said the extended follow-up revealed no new safety concerns, and the maximum tolerated dose of ONO/GS-4059 has not been reached.

Martin Dyer, DPhil, of the University of Leicester in the UK, and his colleagues reported these results in Blood.

The research was funded by Gilead Sciences, Inc., and ONO Pharmaceuticals helped with data analysis.

The study enrolled 90 patients with relapsed or refractory B-cell malignancies, 28 of whom had CLL. Dr Dyer and his colleagues reported follow-up results in CLL patients only.

The patients’ median number of prior treatments was 4 (range, 2-9), and 11 patients were refractory to their last line of therapy. None had received prior treatment with a BTK inhibitor.

The patients received ONO/GS-4059 at varying doses, from 20 mg once daily (QD) to 600 mg QD and a twice-daily (BID) regimen of 300 mg. Six patients were also taking anticoagulant therapy while on study.

Patients were allowed to continue treatment with ONO/GS-4059 if they responded to the drug or maintained stable disease.

Initially, 25 patients were evaluable for response, and 24 of them responded to ONO/GS-4059, for an overall response rate of 96%.

At last follow-up on June 8, 2016, 17 patients were still receiving ONO/GS-4059, and all had a very good partial response.

Dr Dyer said the responses have been similar to those seen with other irreversible BTK inhibitors. Most have involved rapid and almost complete resolution of lymph node masses and rapid improvement in hematological indexes.

“It is clear . . . that the major responses occur rapidly, within the first 3 months of drug, and that, thereafter, improvement occurs at a much slower rate,” Dr Dyer said. “It will be of interest, I think, to look at the remaining patients on study to assess whether responses deepen with time on drug.”

The duration of treatment for these patients ranged from 302 days to 1160 days at last follow-up. They were receiving ONO/GS-4059 at doses ranging from 40 mg QD to 600 mg QD or 300 mg BID, and no maximum tolerated dose had been identified.

Eleven patients (39.3%) discontinued ONO/GS-4059 due to death (n=3), disease progression (n=4), adverse events (AEs, n=3), and sponsor decision due to extended drug interruption (n=1). One of the patients included in the AE group also had concurrent disease progression.

The median progression-free survival was 38.5 months, and the median overall survival was 44.9 months. The median time on study was 32.5 months.

The most common treatment-emergent AEs were bruising (35.7%), neutropenia (35.7%), anemia (32.1%), nasopharyngitis (32.1%), fall (32.1%), cough (28.6%), arthralgia (28.6%), and basal cell carcinoma (28.6%).

The most common grade 3/4 AEs included neutropenia (25%), thrombocytopenia (14.3%), lower respiratory tract infection (14.3%), and anemia (10.7%).

“Our long-term follow-up shows maintained efficacy without toxicity,” Dr Dyer said. “This study is the first report of long-term follow-up of a selective BTK inhibitor, and it is excellent news for patients. We are now doing studies of ONO/GS-4059 in combination with other precision medicines to assess whether these results can be enhanced in patients with CLL and other B-cell malignancies.”

Lower-intensity radiation regimens for patients with early-stage Hodgkin lymphoma (HL) did not shorten progression-free survival (PFS), according to a long-term analysis. Further, for patients with unfavorable early-stage disease, a more intense chemotherapy or radiation regimen conferred no survival benefit.

The German Hodgkin Study Group included patients with early-stage HL who had both early-stage favorable HL and early-stage unfavorable HL. Stephanie Sasse, MD, and her study group colleagues published long-term follow-up findings from multiple trials, conducted from 1993 to 2003, that evaluated risk-adapted treatment strategies to reduce radiation field size and chemotherapy intensity, “aiming at achieving sufficient tumor control while potentially reducing treatment-associated toxicity,” wrote Dr. Sasse and her colleagues of the University Hospital of Cologne (Ger.) (J Clin Oncol. 2017 Apr 18. doi: JCO2016709410).

Trials in favorable HL

Of the 627 patients in the HD7 trial in patients with favorable HL, combined-modality therapy resulted in better rates of PFS (73%) over a 15-year period, compared with extended-field radiotherapy (RT) alone (52%) (hazard ratio, 0.5; 95% confidence interval, 0.3-0.6; P less than 0.001). Another study, called HD10, was in early-stage favorable HL patients. It compared a lower-intensity regimen of two cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) plus 20 Gy involved-field RT with a four-cycle ABVD regimen combined with 30 Gy involved-field RT. The 1,190-patient study achieved a median follow-up of 98 months, finding that the less-intense regimen was not inferior with an identical 10-year PFS of 87% in both arms (HR 1.0; 95% CI 0.6-1.5). Overall survival (OS) was nearly identical as well, at 94% in each arm (HR 0.9; 95% CI, 0.5-1.6).

Both trials HD7 and HD10 tracked the incidence of secondary neoplasias and detected no significant differences between groups, though there was a nonsignificant trend toward more secondary neoplasias for the HD7 patients who received extended-field radiotherapy. These analyses “strongly support the current risk-adapted treatment strategy in early-stage favorable HL,” wrote Dr. Sasse and her coinvestigators.

Trials in unfavorable HL

The HD8 trial enrolled 1,064 patients and followed them for a median 153 months to compare the efficacy of involved-field RT with extended-field RT, finding involved-field RT noninferior for PFS (HR, 1.0; 95% CI, 0.8-1.2). However, the overall 15-year PFS rate of 74% and OS rate of 82% “leave room for improvement,” said the investigators.

Finally, trial HD11 compared two different chemotherapy regimens and two different radiation doses. Patients received four cycles of either ABVD or bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone at baseline dosage (BEACOPP_baseline), followed by 20 or 30 Gy involved-field RT. The study, which followed 1,395 patients for a median of 106 months, had a 2x2 factorial design.

Following the HD11 cohort longitudinally showed that BEACOPP_baseline did not confer a PFS advantage over ABVD for patients receiving the 30 Gy RT regimen (HR 1.1; 95% CI, 0.7-1.5). Nor did patients who received 20 Gy RT have significantly longer PFS with the more intense BEACOPPbaseline chemotherapy regimen (HR 0.8; 95% CI, 0.6-1.1).

Overall survival and the incidence of secondary neoplasias did not differ between trial arms in HD11, said Dr. Sasse and her coinvestigators.

To further explore whether more intense chemotherapy might result in better PFS rates for patients with early-stage unfavorable HL, Dr. Sasse and her colleagues are following long-term results from more recent trial, HD14, that combined two cycles of BEACOPP_escalated and two cycles of ABVD. More short-term toxicity was seen, but patients in this trial arm have significantly better 5-year PFS rates than do those receiving four cycles of ABVD. “The improved tumor control is a relevant outcome parameter for patients,” wrote Dr. Sasse and her colleagues.

The investigators are reserving judgment about whether more radiation exposure and higher doses of alkylating agents and etoposide may eventually result in higher rates of secondary neoplasms. “Subsequent analyses with even longer follow-up will have to confirm that the reduction of RT field size or dose indeed translates into a reduced risk of [secondary neoplasms],” they wrote.

Several of the authors reported multiple relationships with pharmaceutical companies. The study was funded by a grant from the German Cancer Aid.

Lower-intensity radiation regimens for patients with early-stage Hodgkin lymphoma (HL) did not shorten progression-free survival (PFS), according to a long-term analysis. Further, for patients with unfavorable early-stage disease, a more intense chemotherapy or radiation regimen conferred no survival benefit.

The German Hodgkin Study Group included patients with early-stage HL who had both early-stage favorable HL and early-stage unfavorable HL. Stephanie Sasse, MD, and her study group colleagues published long-term follow-up findings from multiple trials, conducted from 1993 to 2003, that evaluated risk-adapted treatment strategies to reduce radiation field size and chemotherapy intensity, “aiming at achieving sufficient tumor control while potentially reducing treatment-associated toxicity,” wrote Dr. Sasse and her colleagues of the University Hospital of Cologne (Ger.) (J Clin Oncol. 2017 Apr 18. doi: JCO2016709410).

Trials in favorable HL

Of the 627 patients in the HD7 trial in patients with favorable HL, combined-modality therapy resulted in better rates of PFS (73%) over a 15-year period, compared with extended-field radiotherapy (RT) alone (52%) (hazard ratio, 0.5; 95% confidence interval, 0.3-0.6; P less than 0.001). Another study, called HD10, was in early-stage favorable HL patients. It compared a lower-intensity regimen of two cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) plus 20 Gy involved-field RT with a four-cycle ABVD regimen combined with 30 Gy involved-field RT. The 1,190-patient study achieved a median follow-up of 98 months, finding that the less-intense regimen was not inferior with an identical 10-year PFS of 87% in both arms (HR 1.0; 95% CI 0.6-1.5). Overall survival (OS) was nearly identical as well, at 94% in each arm (HR 0.9; 95% CI, 0.5-1.6).

Both trials HD7 and HD10 tracked the incidence of secondary neoplasias and detected no significant differences between groups, though there was a nonsignificant trend toward more secondary neoplasias for the HD7 patients who received extended-field radiotherapy. These analyses “strongly support the current risk-adapted treatment strategy in early-stage favorable HL,” wrote Dr. Sasse and her coinvestigators.

Trials in unfavorable HL

The HD8 trial enrolled 1,064 patients and followed them for a median 153 months to compare the efficacy of involved-field RT with extended-field RT, finding involved-field RT noninferior for PFS (HR, 1.0; 95% CI, 0.8-1.2). However, the overall 15-year PFS rate of 74% and OS rate of 82% “leave room for improvement,” said the investigators.

Finally, trial HD11 compared two different chemotherapy regimens and two different radiation doses. Patients received four cycles of either ABVD or bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone at baseline dosage (BEACOPP_baseline), followed by 20 or 30 Gy involved-field RT. The study, which followed 1,395 patients for a median of 106 months, had a 2x2 factorial design.

Following the HD11 cohort longitudinally showed that BEACOPP_baseline did not confer a PFS advantage over ABVD for patients receiving the 30 Gy RT regimen (HR 1.1; 95% CI, 0.7-1.5). Nor did patients who received 20 Gy RT have significantly longer PFS with the more intense BEACOPPbaseline chemotherapy regimen (HR 0.8; 95% CI, 0.6-1.1).

Overall survival and the incidence of secondary neoplasias did not differ between trial arms in HD11, said Dr. Sasse and her coinvestigators.

To further explore whether more intense chemotherapy might result in better PFS rates for patients with early-stage unfavorable HL, Dr. Sasse and her colleagues are following long-term results from more recent trial, HD14, that combined two cycles of BEACOPP_escalated and two cycles of ABVD. More short-term toxicity was seen, but patients in this trial arm have significantly better 5-year PFS rates than do those receiving four cycles of ABVD. “The improved tumor control is a relevant outcome parameter for patients,” wrote Dr. Sasse and her colleagues.

The investigators are reserving judgment about whether more radiation exposure and higher doses of alkylating agents and etoposide may eventually result in higher rates of secondary neoplasms. “Subsequent analyses with even longer follow-up will have to confirm that the reduction of RT field size or dose indeed translates into a reduced risk of [secondary neoplasms],” they wrote.

The emerging role for immunotherapies as an essential component of multiple myeloma therapy is examined in a review article in Leukemia by Cyrille Touzeau, MD, and his colleagues.

The reviewers detail research examining a string of monoclonal antibodies that fell short in earlier evaluations. They focus on the two approved agents that target CD38 (daratumumab) and SLAMF7 (elotuzumab) and have succeeded in combination therapies for patients with relapsed myeloma. These two antibodies, and other immunotherapy possibilities in the pipeline, are expected to have a strong impact on treatment modalities and outcomes in patients with multiple myeloma, including transplant eligible and elderly patients, Dr. Touzeau, of the service d’hématologie clinique, Nantes, France, and his fellow researchers wrote.
