Lugano, Switzerland – A combination of obinutuzumab (Gazyva) and the experimental immunomodulatory agent CC-122 showed “clinically meaningful” activity against relapsed/refractory diffuse large B cell lymphoma (DLBCL) and indolent non-Hodgkin lymphoma (NHL) in a phase 1b study.

Among 38 patients with heavily pretreated, relapsed/refractory DLBCL, follicular lymphoma (FL), or marginal zone lymphoma (MZL), the overall response rate was 66%, including 12 patients (32%) with a complete response (CR), reported Jean-Marie Michot, MD, from the Goustave-Roussy Cancer Center in Villejuif, France.

A chimeric antigen receptor (CAR) T-cell therapy is “highly effective” in high-risk patients with chronic lymphocytic leukemia (CLL), according to researchers.

The CD19 CAR T-cell therapy, JCAR014, produced an overall response rate of 71% and a complete response (CR) rate of 17% in a phase 1/2 trial of patients with relapsed/refractory CLL.

Eighty-three percent of patients experienced cytokine release syndrome (CRS), and 33% developed neurotoxicity. One patient died of CRS/neurotoxicity.

Researchers reported these results in The Journal of Clinical Oncology.

The study was supported by Juno Therapeutics, Life Science Discovery Fund, the Bezos Family, the University of British Columbia Clinical Investigator Program, and grants from the National Cancer Institute and National Institute of Diabetes and Digestive and Kidney Diseases.

The trial included 24 patients with relapsed or refractory CLL. The patients’ median age was 61 (range, 40-73), and they had received a median of 5 prior therapies (range, 3-9). Nineteen patients had progressed while on ibrutinib, and 3 could not tolerate the drug.

“It was not known whether CAR T cells could be used to treat these high-risk CLL patients,” said study author Cameron Turtle, MBBS, PhD, of Fred Hutchinson Cancer Research Center in Seattle, Washington.

“Our study shows that CD19 CAR T cells are a highly promising treatment for CLL patients who have failed ibrutinib.”

Treatment and safety

All 24 patients received lymphodepletion prior to JCAR014. Lymphodepleting regimens consisted of cyclophosphamide, fludarabine, or both.

Patients received JCAR014 at 1 of 3 dose levels—2 x 10⁵, 2 x 10⁶, or 2 x 10⁷ CAR T cells/kg.

Twenty patients (83%) developed CRS—18 with grade 1/2, 1 with grade 4, and 1 with grade 5 CRS.

Eight patients (33%) developed neurotoxicity, all of whom also had CRS. Five patients had grade 3 neurotoxicity, and 1 had grade 5 (same patient with grade 5 CRS).

Initial response

The overall response rate, according to IWCLL criteria, was 71%. Seventeen patients responded, 4 with CRs and 13 with partial responses (PRs).

One of the patients who achieved a CR had received a second dose of JCAR014, without lymphodepletion, 14 days after the first dose.

One of the patients with a PR initially had stable disease (SD) at the 4-week assessment but was in PR 8 weeks later.

Twenty-one patients had a bone marrow evaluation 4 weeks after treatment with JCAR014. Seventeen of these patients (81%) had no residual disease according to high-resolution flow cytometry.

The researchers also performed IGH sequencing of bone marrow in 12 patients with no residual disease by flow cytometry. Seven of these patients (58%) had no detectable malignant IGH sequences 4 weeks after receiving JCAR014.

Second dose

Six patients who had persistent disease or who relapsed after receiving JCAR014 received a second cycle of lymphodepletion and JCAR014 at the same dose (n=1) or a 10-fold higher dose (n=5).

Four of these patients developed CRS (2 grade 3 or higher), and 1 developed reversible neurotoxicity (grade 3).

Two patients achieved a CR and had no residual disease by flow cytometry or IGH sequencing.

Survival

Responders had significantly superior progression-free survival (PFS) and overall survival (OS) compared to non-responders.

The median PFS was 9.8 months in patients who achieved a CR, was not reached in those with a PR, and was 1.1 months in patients with progressive disease (PD) or SD (P=0.0068 for CR/PR vs SD/PD).

The median OS was not reached in patients who achieved a CR or a PR, but it was 11.2 months in patients with SD or PD (P=0.0011 for CR/PR vs SD/PD).

The researchers also found that IGH sequencing revealed patients with durable PFS.

The median PFS was not reached in patients with no malignant IGH sequences, but it was 8.5 months in IGH-positive patients (P=0.253). The median OS was not reached in either group (P=0.25).

on Malignant Lymphoma

LUGANO, SWITZERLAND—A 4-drug regimen has demonstrated efficacy in a phase 2 trial of patients with treatment-naïve extranodal natural killer/T-cell lymphoma (ENKTL).

Treatment with gemcitabine, PEG-asparaginase, dexamethasone, and methotrexate (GAD-M) produced a 94% overall response rate (ORR) and an 83% complete response (CR) rate in this trial.

Responses and survival rates were higher in patients with stage I/II disease, who also received radiotherapy, than in patients with stage III/IV disease.

Grade 1/2 toxicities were frequent, but there were few grade 3/4 non-hematologic toxicities. One patient died of treatment-related toxicity.

Zhiming Li, of Sun Yet-sen University Cancer Center in Guangzhou, China, presented these results at the 14th International Conference on Malignant Lymphoma (ICML).

Patients and treatment

The trial enrolled 41 patients with treatment-naïve ENKTL, and 36 of them were evaluable.

The patients’ median age was 45 (range, 18-75), and 30.6% were female. Most patients (86.1%) had stage I/II disease, 13.9% had an ECOG performance status of 2 or greater, and 41.7% had an IPI score of 2 or greater.

The GAD-M regimen consisted of:

• Gemcitabine given at 1000 mg/m² via intravenous drip on days 1 and 8
• PEG-asparaginase given at 2500 U/m² intramuscularly on day 1
• Dexamethasone given at 20 mg via intravenous drip on days 1 to 3
• Methotrexate given at 3000 mg/m² via continuous, 12-hour infusion on day 1.

The regimen was repeated every 3 weeks.

For patients with stage I/II disease, 2 to 4 cycles of the GAD-M regimen was followed by extensive involved-field radiotherapy and an additional 2 to 4 cycles. For patients with stage III/IV disease, GAD-M was repeated for 6 cycles.

Response and survival

The ORR was 94.4%, both after 2 cycles of GAD-M and after 6 cycles. The CR rate was 50% after 2 cycles and 83.3% after 6 cycles.

In patients with stage I/II disease, the ORR was 100% after 2 cycles and 6 cycles. The CR rate was 54.8% after 2 cycles and 90.3% after 6 cycles.

In patients with stage III/IV disease, the ORR was 60% after 2 cycles and 6 cycles. The CR rate was 20% after 2 cycles and 40% after 6 cycles.

At median follow-up of 23.3 months, the estimated 3-year progression-free survival (PFS) was 72.1%, and the overall survival (OS) was 76.3%.

For patients with stage I/II disease, the PFS was 77.3%, and the OS was 79.3%. For patients with stage III/IV disease, the PFS was 40%, and the OS was 60%.

Safety

Hematologic adverse events (AEs) included anemia (97.2% total, 52.8% grade 3/4), leukocytopenia (94.4%, 27.8% grade 3/4), neutropenia (88.9%, 5.6% grade 3), and thrombocytopenia (47.2%, 13.9% grade 3/4).

Non-hematologic AEs included hypoalbuminemia (100%, 5.6% grade 3), increased transaminases (88.9%, 5.6% grade 3), hyperbilirubinemia (52.8%, 11.1% grade 3), decreased fibrinogen (19.4%, 11.1% grade 4), vomiting (13.9%, 2.8% grade 5), increased creatinine (8.3%, 2.8% grade 3), and abdominal pain (5.6% grade 1).

The grade 5 treatment-related AE occurred in a 61-year-old man. He died of electrolyte disorders caused by severe vomiting.

Three case reports published in The New England Journal of Medicine describe the successful use of PD-1 inhibitors in gray zone lymphoma.

Two patients who had failed treatment with DA-EPOCH-R (dose-adjusted etoposide, doxorubicin, and cyclophosphamide with vincristine, prednisone, and rituximab) ultimately responded to treatment with pembrolizumab.

Another patient—who had previously received 2 chemotherapy regimens, monotherapy with brentuximab vedotin, and radiation—responded to treatment with nivolumab.

Pembrolizumab treatment

An 18-year-old woman with mediastinal gray-zone lymphoma initially had a partial response to DA-EPOCH-R. However, she progressed 6 weeks after salvage radiotherapy.

She went on to receive pembrolizumab, had a complete metabolic response, and proceeded to allogeneic transplant after 235 days of treatment.

A 76-year-old man with mediastinal gray-zone lymphoma also had a partial response to DA-EPOCH-R but later progressed.

He proceeded to pembrolizumab and had a complete metabolic response. He was still in remission on day 381 of treatment.

Nivolumab treatment

The patient who received nivolumab is Bobbie Flexer, an 80-year-old retired mathematics professor.

“For me, trying nivolumab was a binary choice: I could try the drug or I could give up,” Flexer said.

She had initially achieved a complete metabolic response to DA-EPOCH-R, but her disease progressed after 6 cycles of treatment.

“Given Bobbie’s age and her resistance to chemotherapy, it was difficult to simply increase her dose,” said Flexer’s oncologist, Manali Kamdar, MD, of the University of Colorado School of Medicine in Aurora.

“Bobbie’s tumor biopsy expressed a protein called CD30, and so we started her on brentuximab, which targets these CD30 cells. Unfortunately, Bobbie’s disease progressed through multiple cycles of brentuximab. Subsequently, we switched her to another combined chemotherapy—namely, gemcitabine with oxaliplatin [plus rituximab].”

When that regimen and mediastinal radiation both proved unsuccessful, Dr Kamdar started Flexer on nivolumab.

“Within one dose, she was in less pain, and she looked much better,” Dr Kamdar said.

A PET scan after 6 doses showed that Flexer’s disease was in complete remission, and she was still in remission on day 161 of treatment.

She did experience adverse effects, including 2 bouts of pneumonitis, which were successfully treated with prednisone.

Flexer also experienced an uptick in pancreas enzymes that caused high blood glucose levels. She is learning to treat that side effect with insulin. And dietitians helped her manage expected gut-related side effects of nivolumab.

To Dr Kamdar, Flexer’s case was striking enough to warrant submitting a report to NEJM.

Coincidentally, the journal had just received 2 similar case reports from the National Institutes of Health, in which researchers had used pembrolizumab to target gray zone lymphoma in a nearly identical way.

Together, these cases suggest a new strategy for treating gray zone lymphoma.

She did experience adverse effects, including 2 bouts of pneumonitis, which were successfully treated with prednisone.

Flexer also experienced an uptick in pancreas enzymes that caused high blood glucose levels. She is learning to treat that side effect with insulin. And dietitians helped her manage expected gut-related side effects of nivolumab.

To Dr Kamdar, Flexer’s case was striking enough to warrant submitting a report to NEJM.

Coincidentally, the journal had just received 2 similar case reports from the National Institutes of Health, in which researchers had used pembrolizumab to target gray zone lymphoma in a nearly identical way.

Together, these cases suggest a new strategy for treating gray zone lymphoma.

Three case reports published in The New England Journal of Medicine describe the successful use of PD-1 inhibitors in gray zone lymphoma.

Two patients who had failed treatment with DA-EPOCH-R (dose-adjusted etoposide, doxorubicin, and cyclophosphamide with vincristine, prednisone, and rituximab) ultimately responded to treatment with pembrolizumab.

Another patient—who had previously received 2 chemotherapy regimens, monotherapy with brentuximab vedotin, and radiation—responded to treatment with nivolumab.

Pembrolizumab treatment

An 18-year-old woman with mediastinal gray-zone lymphoma initially had a partial response to DA-EPOCH-R. However, she progressed 6 weeks after salvage radiotherapy.

She went on to receive pembrolizumab, had a complete metabolic response, and proceeded to allogeneic transplant after 235 days of treatment.

A 76-year-old man with mediastinal gray-zone lymphoma also had a partial response to DA-EPOCH-R but later progressed.

He proceeded to pembrolizumab and had a complete metabolic response. He was still in remission on day 381 of treatment.

Nivolumab treatment

The patient who received nivolumab is Bobbie Flexer, an 80-year-old retired mathematics professor.

“For me, trying nivolumab was a binary choice: I could try the drug or I could give up,” Flexer said.

She had initially achieved a complete metabolic response to DA-EPOCH-R, but her disease progressed after 6 cycles of treatment.

“Given Bobbie’s age and her resistance to chemotherapy, it was difficult to simply increase her dose,” said Flexer’s oncologist, Manali Kamdar, MD, of the University of Colorado School of Medicine in Aurora.

“Bobbie’s tumor biopsy expressed a protein called CD30, and so we started her on brentuximab, which targets these CD30 cells. Unfortunately, Bobbie’s disease progressed through multiple cycles of brentuximab. Subsequently, we switched her to another combined chemotherapy—namely, gemcitabine with oxaliplatin [plus rituximab].”

When that regimen and mediastinal radiation both proved unsuccessful, Dr Kamdar started Flexer on nivolumab.

“Within one dose, she was in less pain, and she looked much better,” Dr Kamdar said.

A PET scan after 6 doses showed that Flexer’s disease was in complete remission, and she was still in remission on day 161 of treatment.

She did experience adverse effects, including 2 bouts of pneumonitis, which were successfully treated with prednisone.

Flexer also experienced an uptick in pancreas enzymes that caused high blood glucose levels. She is learning to treat that side effect with insulin. And dietitians helped her manage expected gut-related side effects of nivolumab.

The chimeric antigen receptor (CAR) T-cell therapy CTL019 produced a high response rate in a phase 2 trial of adults with relapsed/refractory diffuse large B-cell lymphoma (DLBCL), according to researchers.

An interim analysis of the JULIET trial revealed a 3-month overall response rate (ORR) of 45%.

Thirty-seven percent of patients had a complete response (CR), and all of the patients who were in CR at 3 months were still in CR at the data cutoff point.

This confirms the high response rates and durable responses observed in a previous single-center trial*, said JULIET investigator Gilles Salles, MD, PhD, of Hospices Civils de Lyon in Lyon, France.

Dr Salles presented results from JULIET at the 22nd Congress of the European Hematology Association (EHA) in Madrid, Spain (abstract LB2604).

The results were also presented at the 14th International Conference on Malignant Lymphoma (ICML) in Lugano, Switzerland (abstract 007).

The study was sponsored by Novartis.

Patients

JULIET enrolled 141 patients age 18 and older with relapsed/refractory DLBCL.

Forty-three patients discontinued the study before receiving CTL019—28 due to progressive disease (including 16 deaths), 9 due to an inability to manufacture CTL019, 2 due to adverse events, 1 due to investigator decision, 1 due to study withdrawal, and 1 due to protocol deviation.

Eighty-five patients were infused. The remaining 13 patients were pending infusion at the data cutoff—December 20, 2016.

The median age of the 85 infused patients was 56 (range, 24-75). Ninety-six percent of patients had DLBCL not otherwise specified. Fifty-one percent had germinal center B-cell type DLBCL.

Fifty-four percent of patients had an ECOG performance status of 0, and 46% had a status of 1. Fifty-three percent of patients had stage IV disease, and 8% had bone marrow involvement.

Forty percent of patients had 2 prior lines of antineoplastic therapy, 29% had 3, and 31% had 4 to 7 prior lines.

Forty-one percent of patients were refractory to their last therapy, and 59% had relapsed after their last therapy. Fifty-one percent of patients had prior autologous stem cell transplant.

Treatment

Seventy-six patients (89%) received bridging chemotherapy to prevent disease progression during CTL019 manufacturing. This treatment was completed 2 to 14 days prior to CTL019 infusion.

The median CTL019 cell dose was 3.1 x 10⁸ (range, 0.1-6.0 x 10⁸).

Response

Fifty-one patients were evaluated for response. The median time from infusion to data cutoff was 3.7 months.

The best ORR was 59%, with a CR rate of 43% and a partial response rate of 16%. Twelve percent of patients had stable disease, and 24% progressed.

At 3 months, the ORR was 45%. The CR rate was 37%, and the partial response rate was 8%.

“All patients in CR at 3 months remained in CR at follow-up, and the median duration of response was not reached,” Dr Salles noted.

None of the responders went on to receive a transplant.

Safety

All 85 patients were evaluated for safety. Adverse events of special interest, occurring within 8 weeks of CTL019 infusion, were:

• Cytokine release syndrome—57% all grades, 17% grade 3, 9% grade 4
• Infections—27% all grades, 12% grade 3, 1% grade 4
• Cytopenias not resolved by day 28—26% all grades, 13% grade 3, 8% grade 4
• Neurologic events—21% all grades, 9% grade 3, 4% grade 4
• Febrile neutropenia—14% all grades, 13% grade 3, 1% grade 4
• Tumor lysis syndrome—1% grade 3.

“Adverse events were reversible and effectively managed at the different centers by appropriately trained study personnel,” Dr Salles noted. “There were no CTL019-related deaths and no cerebral edema.”

LUGANO, SWITZERLAND – Copanlisib, an investigational intravenous inhibitor of phosphatidylinositol 3-kinase (PI3K), was associated with “promising” efficacy and a better safety profile than has been seen with oral PI3K inhibitors in patients with relapsed or refractory indolent lymphomas.

In a phase 2 trial of the drug as monotherapy in patients with indolent lymphomas, copanlisib was associated with an overall response rate of 58.6% among 104 patients with follicular lymphoma (FL), including 14.4% complete responses (CR) and 44.2% partial responses (PR), reported Martin Dreyling, MD, of the Universität München-Grosshadern in Munich, Germany.

“The favorable risk-benefit profile of this compound suggests further [need for] testing in follicular lymphoma. My personal interpretation is that the different safety profile is due to the intermittent dosing and the IV application, avoiding adverse cause-effect both in the gut and the liver,” he said at the 14th International Conference on Malignant Lymphoma.

Dr. Dreyling noted that the oral PI3K inhibitor idelalisib (Zydelig) is approved for the treatment of patients with relapsed chronic lymphocytic leukemia in combination with rituximab and in patients with relapsed FL or small lymphocytic lymphomas (SLL) who have received at least two prior lines of systemic therapy. This agent, however, carries a black box warning about fatal and serious toxicities, including hepatic events, severe diarrhea, colitis, pneumonitis, infections, and intestinal perforation.

Copanlisib inhibits all isoforms of P13K but is predominantly active against the alpha and delta isoforms of the kinase. The alpha form, expressed in many cell types, is involved in insulin signaling and angiogenesis and in resistance mechanisms to lymphoma. The delta form, expressed in leukocytes, is involved in B-cell signaling, development, and survival, making PIK3 an attractive target, Dr. Dreyling explained.

The study included patients with indolent B-cell lymphomas, including FL grades 1-3a, marginal zone lymphoma, SLL, or lymphoplasmacytic lymphoma/Waldenstrom macroglobulinemia (LPL/WM) for whom at least two prior lines of therapy had failed.

The patients received copanlisib 60 mg IV on days 1, 8, and 15 of each 28-day cycle until disease progression or unacceptable toxicity.

Of 142 assigned to and started on treatment, 46 patients (32.3%) remained on treatment at the time of data cutoff. Of the 96 patients (67.7%) who discontinued, 35 did so because of adverse events, 36 discontinued for radiologic or clinical evidence of progression, 16 withdrew, 5 were discontinued on the treating physician’s decision, and 4 stopped for other, unspecified reasons.

Among all 142 patients, the median duration of therapy was 22 weeks and the median number of cycles was 5.5. In all, 26.1% of patients required a dosage reduction to 45 mg, and 5.6% required reduction to 30 mg.

As noted, the objective tumor response rate (ORR) among patients was 58.6% for 104 patients with FL. For the 23 patients with marginal zone lymphoma, the ORR was 69.6%, consisting of two complete and 14 partial responses. Among eight patients with SLL, there were six partial responses and no complete responses. For the six patients with LPL/WM, there was one partial response.

The overall median duration of response was 22.6 months. Among patients with refractory disease and in all patients with FL the median duration of response was 12.2 months.

The median progression-free survival after 24 months of follow-up was 11.2 months for all patients. The median overall survival has not been reached.

The most frequent adverse events of grade 3 or 4 were hyperglycemia in 40.1% (33.1% grade 3 and 7.0% grade 4) and hypertension in 22.5% (all grade 3).

Grade 3 diarrhea, a significant problem with idelalisib, occurred in 4.2% of patients, and there were no grade 4 events.

Grade 3 pneumonitis was seen in two patients, and one had grade 4 colitis. There were three drug related deaths, including one patient each from lung infection, respiratory failure, or thromboembolic event..

The study was supported by Bayer. Dr. Dreyling disclosed receiving honoraria from the company and serving on a scientific/advisory board for the company.

Micrograph showing CLL

LUGANO, SWITZERLAND—Results of a phase 1 study suggest a 2-drug combination may be safe and effective in patients with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) and follicular lymphoma (FL).

The ongoing study is a test of the BTK inhibitor BGB-3111 and the anti-CD20 antibody obinutuzumab.

The overall response rate (ORR) with this combination was 81% in the entire study population, 89% in treatment-naïve CLL/SLL patients, 92% in relapsed/refractory CLL/SLL patients, and 73% in relapsed/refractory FL patients.

The rate of serious adverse events (AEs) was 24% in both CLL/SLL and FL patients.

These results were presented at the 14th International Conference on Malignant Lymphoma (ICML). The research was sponsored by BeiGene, Ltd.

“This clinical trial is supported by preclinical work suggesting that BGB-3111 may combine well with antibodies that rely on antibody-dependent cell-mediated cytotoxicity, such as obinutuzumab, because of less off-target inhibition of interleukin-2-inducible T-cell kinase,” said study investigator Constantine Tam, MD, of St. Vincent’s Hospital in Melbourne, Australia.

“The preliminary clinical results to date suggest that the combination is well tolerated and highly active in patients with CLL or SLL and FL. Complete responses have already been observed in patients with both disease types, including CLL or SLL patients with high-risk features, despite a very short follow-up time.”

The trial consists of a dose-escalation phase and a dose-expansion phase in disease-specific cohorts, which include treatment-naive or relapsed/refractory CLL/SLL and relapsed/refractory FL.

The dose-escalation component is testing BGB-3111 at 320 mg once daily or 160 mg twice daily in 28-day cycles, in combination with obinutuzumab. Obinutuzumab is administered in line with standard CLL dosing (3 loading doses of 1000 mg weekly, followed by 1000 mg on day 1 of cycles 2 to 6).

The ongoing dose-expansion component is testing doses of BGB-3111 at 160 mg twice daily with the same obinutuzumab schedule.

As of the data cutoff (March 31, 2017), 45 patients with CLL/SLL and 17 patients with FL were enrolled in the trial.

Patient characteristics

The median age was 68 (range, 28-82) in the CLL/SLL patients and 56 (range, 41-86) in the FL patients.

ECOG performance status was 0 in 42% of CLL/SLL patients, 1 in 56% of these patients, and 2 in 2%. ECOG performance status was 0 in 82% of FL patients, 1 in 12% of these patients, and 2 in 6%.

Twenty CLL/SLL patients were treatment-naïve, and 25 had relapsed/refractory disease. All 17 FL patients had relapsed/refractory disease.

The median number of prior therapies was 1 (range, 1-4) in the relapsed/refractory CLL/SLL patients and 3 (range, 1-7) in the FL patients.

Safety

At the time of the data cutoff, BGB-3111 was deemed well tolerated in patients with CLL/SLL and FL.

The most frequent AEs of any cause occurring in at least 15% of patients with CLL/SLL were petechiae/purpura/contusion (33%), neutropenia (31%), thrombocytopenia (22%), fatigue (18%), pyrexia (18%), upper respiratory tract infection (18%), and diarrhea (16%).

Most of these events were grade 1/2. The exceptions were grade 3/4 neutropenia (20%) and grade 3/4 thrombocytopenia (4%).

The most frequent AEs in FL patients were petechiae/purpura/contusion (35%), fatigue (29%), cough (18%), diarrhea (18%), dizziness (18%), headache (18%), insomnia (18%), nausea (18%), and upper respiratory tract infection (18%). All of these events were grade 1/2.

Serious AEs occurred in 24% of both the CLL/SLL patients and the FL patients.

Infusion-related reactions occurred in 24% of CLL/SLL patients and 6% of FL patients. Nearly all cases were grade 1/2. The exception was 1 grade 4 case in a CLL/SLL patient.

There were no cases of serious hemorrhage (≥ grade 3 hemorrhage or central nervous system hemorrhage of any grade) or atrial fibrillation.

One patient discontinued treatment due to an AE—squamous cell carcinoma. This patient had a prior history of squamous cell carcinoma.

Efficacy

At the time of the data cutoff, 43 patients with CLL/SLL (18 treatment-naive, 25 relapsed/refractory) and 15 patients with relapsed/refractory FL had greater than 12 weeks of follow-up and were evaluable for efficacy.

In treatment-naive CLL/SLL, after a median follow-up of 7.0 months (range, 2.8–11.8 months), the ORR was 89%. The complete response (CR) rate was 22%, the rate of partial response (PR) was 67%, and the rate of stable disease (SD) was 11%.

In relapsed/refractory CLL/SLL, at a median follow-up of 8.0 months (range, 3.8–14.0 months) the ORR was 92%. The CR rate was 16%, the PR rate was 76%, and 4% of patients had SD.

One patient (4%) with relapsed/refractory CLL/SLL had progressive disease (Richter’s transformation).

In relapsed/refractory FL, at a median follow-up of 6.2 months (range, 1.2–10.7 months), the ORR was 73%. The CR rate was 33%, the PR rate was 40%, and 13% of patients had SD.

Two patients (13%) with relapsed/refractory FL had progressive disease.

On the basis of these data, BeiGene plans to expand its global registrational program for BGB-3111 to include a phase 2 trial of BGB-3111 in combination with obinutuzumab compared to obinutuzumab alone in patients with relapsed/refractory FL.

The company is also planning a phase 3 trial comparing BGB-3111 with bendamustine plus rituximab in patients with treatment-naive CLL.

LUGANO, SWITZERLAND—Results of a phase 1 study suggest a 2-drug combination may be safe and effective in patients with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) and follicular lymphoma (FL).

The ongoing study is a test of the BTK inhibitor BGB-3111 and the anti-CD20 antibody obinutuzumab.

The overall response rate (ORR) with this combination was 81% in the entire study population, 89% in treatment-naïve CLL/SLL patients, 92% in relapsed/refractory CLL/SLL patients, and 73% in relapsed/refractory FL patients.

The rate of serious adverse events (AEs) was 24% in both CLL/SLL and FL patients.

These results were presented at the 14th International Conference on Malignant Lymphoma (ICML). The research was sponsored by BeiGene, Ltd.

“This clinical trial is supported by preclinical work suggesting that BGB-3111 may combine well with antibodies that rely on antibody-dependent cell-mediated cytotoxicity, such as obinutuzumab, because of less off-target inhibition of interleukin-2-inducible T-cell kinase,” said study investigator Constantine Tam, MD, of St. Vincent’s Hospital in Melbourne, Australia.

“The preliminary clinical results to date suggest that the combination is well tolerated and highly active in patients with CLL or SLL and FL. Complete responses have already been observed in patients with both disease types, including CLL or SLL patients with high-risk features, despite a very short follow-up time.”

The trial consists of a dose-escalation phase and a dose-expansion phase in disease-specific cohorts, which include treatment-naive or relapsed/refractory CLL/SLL and relapsed/refractory FL.

The dose-escalation component is testing BGB-3111 at 320 mg once daily or 160 mg twice daily in 28-day cycles, in combination with obinutuzumab. Obinutuzumab is administered in line with standard CLL dosing (3 loading doses of 1000 mg weekly, followed by 1000 mg on day 1 of cycles 2 to 6).

High-dose chemotherapy with upfront autologous stem cell transplantation did not meaningfully improve survival at 5 years in a phase 3 trial of 399 patients under age 66 years with intermediate to high– or high-risk untreated diffuse large B-cell lymphoma.

Rates of treatment failure-free survival at 2 years were 71% for patients who received rituximab dose–dense chemotherapy followed by autologous stem cell transplantation (ASCT) and 62% for patients who received only the rituximab regimen (hazard ratio, 0.65; 95% confidence interval, 0.47-0.91; P = .01), Annalisa Chiappella, MD, of Azienda Ospedaliero Universitaria Città della Salute e della Scienza di Torino (Italy) reported with her associates in Lancet Oncology.

Narrow insurance plan coverage may prevent US cancer patients from receiving care at “high-quality” cancer centers, according to research published in the Journal of Clinical Oncology.

Researchers found that “narrow network” insurance plans—lower-premium plans with reduced access to certain providers—are more likely to exclude doctors associated with National Cancer Institute (NCI) and National Comprehensive Cancer Network (NCCN) cancer centers.

These centers are recognized for their scientific and research leadership, quality and safety initiatives, and access to expert physicians and clinical trials.

NCCN member institutions are particularly recognized for higher-quality care, and treatment at NCI-designated cancer centers is associated with lower mortality than other hospitals, particularly among more severely ill patients and those with more advanced disease.

For this study, researchers examined cancer provider networks offered on the 2014 individual health insurance exchanges and then determined which oncologists were affiliated with NCI-designated and NCCN cancer centers.

The researchers found that narrower networks were less likely to include physicians associated with NCI-designated and NCCN member institutions.

“To see such a robust result was surprising,” said study author Laura Yasaitis, PhD, of the University of Pennsylvania in Philadelphia.

“The finding that narrower networks were more likely to exclude NCI and NCCN oncologists was consistent no matter how we looked at it. This is not just a few networks. It’s a clear trend.”

The researchers said the results point to 2 major problems—transparency and access.

“Patients should be able to easily figure out whether the physicians they might need will be covered under a given plan,” said study author Justin E. Bekelman, MD, of the University of Pennsylvania.

The researchers suggested that insurers report doctor’s affiliations with NCI and NCCN cancer centers so that consumers can make more informed choices.

The team also suggested that insurers offer mechanisms that would allow patients to seek care out of network without incurring penalties in exceptional circumstances.

“If patients have narrow network plans and absolutely need the kind of complex cancer care that they can only receive from one of these providers, there should be a standard exception process to allow patients to access the care they need,” Dr Bekelman said.
