A small retrospective study of survivors of childhood acute lymphoblastic leukemia (ALL) or non-Hodgkin lymphoma (NHL) has found that phosphorylated Tau (p-Tau) in patients’ cerebrospinal fluid (CSF) is a predictor of late neurocognitive consequences.

Investigators compared intellectual performance, memory, and executive functioning between survivors and control subjects and observed that CSF levels of p-Tau during treatment and total intrathecal methotrexate dose negatively correlated with intellectual performance.

They suggest that identifying at-risk children early “could inspire interventions to prevent or remediate chemotherapy-induced cognitive sequelae.”

The investigators enrolled 31 nonirradiated adults, 27 who had had ALL and 4 NHL. They compared the survivors to 35 age-matched controls.

All study participants were a mean age of 21.5 years (range, 16.1–29.8). The mean age of the survivors at diagnosis was 6.4 years.

"Our team collected samples of brain fluid during the cancer treatment,” Rudi D’Hooge, PhD, of KU Leuven in Belgium, said. “We analyzed the p-Tau levels to measure the damage to the brain cells."

Investigators assessed intelligence, memory, and executive function using Wechsler Adult Intelligence Scale (WAIS IV), Rey Auditory Verbal Learning Test (AVLT), and Amsterdam Neuropsychological Tasks (ANT), respectively.

Statistical analysis included two-sided, one-way analysis of covariance (ANCOVA) with survivor group vs control group as an independent factor.  Parental socioeconomic status was a covariate.

Dr D’Hooge and colleagues published their findings in JNCI, the Journal of the National Cancer Institute.

Findings

Investigators found that survivors had statistically significant lower total intelligence (P=0.001), verbal intelligence (P=0.02), and performance intelligence (P=0.007) quotients than controls.

They also found a negative correlation between CSF p-Tau, but not CSF Tau, levels and total intelligence (P=0.02), verbal intelligence (P=0.001), and performance intelligence (P=0.04) quotients.

Only performance intelligence was negatively correlated with total intrathecal methotrexate (P=0.007).

And because total intrathecal methotrexate dose and CSF p-Tau were not significantly correlated (P=0.29), the investigators believe intervening factors increase CSF p-Tau independently from methotrexate dose.

Results of subset tests revealed that cognitive flexibility (set-shifting and working memory), and processing speed were affected (P<0.05).

However, long-term memory, focused and sustained attention, and inhibition appeared unaffected (P>0.05).

The investigators believe these differences in vulnerability of cognitive functions parallel patient age at time of development.

For example, long-term memory, focused and sustained attention, and inhibition develop before children reach 6 years, the mean age at which the survivor cohort was diagnosed.

But set-shifting, working memory, and processing speed mature during adolescence, after the patients were diagnosed and treated.

Limitations of the study, according to the investigators, include its retrospective and cross-sectional design, the relatively small sample size, and the lack of pretreatment neurocognitive data.

Nevertheless, they believe the study should encourage the use of the CSF biomarker, intrathecal methotrexate dose, and age at therapy initiation in neurotoxicity assessments to identify children at risk for long-term sequelae.

"If we systematically measure these p-Tau levels in the future," Iris Elens, MD, also of KU Leuven, said, "we can offer specific help to children with high values. With early coaching aimed at the most relevant functions we can prevent problems that would otherwise manifest 10 to 15 years after the treatment."

The US Food and Drug Administration (FDA) approved a new, subcutaneous (SC) formulation of rituximab with hyaluronidase human (Rituxan Hycela™).

The new formulation includes the same monoclonal antibody as intravenous rituximab, but is combined with an enzyme that helps to deliver rituximab under the skin.

The new treatment reduces administration time from 1.5 hours or more for intravenous rituximab to 5 to 7 minutes for the subcutaneous injection.

It is approved for use in adults with previously untreated and relapsed or refractory follicular lymphoma (FL), previously untreated diffuse large B-cell lymphoma (DLBCL), and previously untreated and previously treated chronic lymphocytic leukemia (CLL).

“[P]eople with 3 of the most common blood cancers now have a new treatment option which provides efficacy comparable with intravenous Rituxan and can be delivered under the skin in minutes instead of hours through IV infusion,” said Sandra Horning, MD, chief medical officer of Genentech.

Rituxan Hycela is manufactured by Genentech, Inc, a member of the Roche Group, and jointly marketed by Biogen and Genentech USA, Inc.

“People who benefit from Rituxan may receive years of repeated treatments for their blood cancer, so an option that reduces the administration time can be important,” she noted.

The FDA based its decision on results from 4 clinical studies:

• SABRINA (NCT01200758): Phase 3 combination study with chemotherapy and maintenance study in previously untreated FL
• SAWYER (NCT01292603): Phase 1b study in previously untreated CLL
• MabEase (NCT01649856): Phase 3 study in previously untreated DLBCL
• PrefMab (NCT01724021): Phase 3 patient preference study in previously untreated FL and DLBCL

This last study showed that 77% of patients preferred subcutaneous over intravenous administration, primarily because it reduced administration time.

Together, these trials represented nearly 2,000 people and demonstrated that subcutaneous administration of rituximab/hyaluronidase resulted in non-inferior levels of rituximab in the blood compared to intravenous rituximab.

And the subcutaneous formulation also demonstrated comparable clinical efficacy outcomes to the intravenous formulation.

Patients must have had at least 1 full dose of intravenous rituximab without severe adverse reactions before receiving the subcutaneous injection. There is a higher risk of certain severe adverse reactions during the first infusion.

The safety profile of rituximab/hyaluronidase is also comparable to intravenous rituximab, except for cutaneous reactions.

The most common (≥20%) adverse reactions observed with rituximab/hyaluronidase were:

• In FL, infections, neutropenia, nausea, constipation, cough, and fatigue.
• In DLBCL, infections, neutropenia, alopecia, nausea, and anemia.
• In CLL, infections, neutropenia, nausea, thrombocytopenia, pyrexia, vomiting, and erythema at the injection site.

Rituxan Hycela will be available in the US within 1 to 2 weeks, according to the manufacturer. Intravenous rituximab will continue to be available.

A subcutaneous formulation of rituximab (MabThera) had previously been approved for use in European markets by the European Commission.

Mantle cell lymphoma

LUGANO, SWITZERLAND—A chemotherapy-free combination regimen has demonstrated “favorable” safety and efficacy in patients with advanced chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) and non-Hodgkin lymphoma (NHL), according to researchers.

They found that treatment with ublituximab, umbralisib, and ibrutinib produced responses in patients with CLL/SLL, marginal zone lymphoma (MZL), mantle cell lymphoma (MCL), follicular lymphoma (FL), and diffuse large B-cell lymphoma (DLBCL).

Many of these patients are still receiving the combination, some of them beyond 1 year, said Lorretta Nastoupil, MD, of MD Anderson Cancer Center in Houston, Texas.

She presented results with the treatment at the 14th International Conference on Malignant Lymphoma (ICML).

The research was sponsored by TG Therapeutics, the company developing ublituximab (TG-1101) and umbralisib (TGR-1202).

Patients and treatment

Dr Nastoupil presented data on 38 patients—20 with CLL/SLL, and 18 with NHL. Three of the CLL/SLL patients were treatment-naïve. The rest had relapsed/refractory disease.

All NHL patients had relapsed/refractory disease—6 with DLBCL, 6 with FL, 4 with MCL, and 2 with MZL.

For the entire cohort, the median age was 65 (range, 32-85), and most patients (n=29) were male. They had received a median of 3 prior treatment regimens (range, 0-6).

In this trial, the patients received:

• Ublituximab at 900 mg
• Ibrutinib at 420 mg (CLL/SLL) or 560 mg (NHL)
• Umbralisib at 400 mg, 600 mg, or 800 mg.

Eighty-one percent of patients have been on study for more than 6 months. The median time on study is 11.1 months (range, 0.4 to 30+ months).

Safety

There was 1 dose-limiting toxicity in the CLL cohort (umbralisib at 400 mg)—reactivated varicella zoster. And 2 patients discontinued treatment due to an adverse event (AE)—1 due to sepsis and 1 due to pneumonia.

Neutropenia (18%) and pneumonia (11%) were the only grade 3/4 AEs that occurred in more than 10% of patients. Other grade 3/4 AEs included thrombocytopenia (8%), diarrhea (3%), dizziness (3%), pyrexia (3%), rash (3%), anemia (3%), dyspnea (3%), and stomatitis (3%).

The most common AEs of any grade were diarrhea (47%), fatigue (47%), dizziness (37%), insomnia (34%), nausea (34%), neutropenia (32%), cough (32%), and infusion-related reactions (32%).

Efficacy

Thirty-six patients were evaluable for efficacy—19 with CLL/SLL and 17 with NHL patients. Two patients discontinued treatment before the first efficacy assessment—1 due to pneumonia and 1 at investigator discretion.

For the entire cohort, the overall response rate (ORR) was 83%.

In the CLL/SLL cohort, the ORR was 100% (19/19), and the complete response (CR) rate was 32% (n=6). However, 4 of the 6 CRs are pending bone marrow confirmation.

Dr Nastoupil noted that 8 of the CLL patients had a 17p and/or 11q deletion, and 3 had previously received treatment with a BTK and/or PI3Kδ inhibitor.

One patient who was refractory to both idelalisib and ibrutinib achieved a CR with the triplet regimen, and this response has been ongoing for more than 1.5 years.

Among patients with NHL, the ORR was 100% in patients with MZL (2/2) and MCL (4/4). The ORR was 80% (4/5) in FL patients, and 17% (1/6) in DLBCL patients.

The CR rate was 50% in patients with MZL (1/2) and MCL (2/4) and 20% in patients with FL (1/5).

Dr Nastoupil pointed out that the FL patients were heavily pretreated. Two of them had received an autologous stem cell transplant, 1 was refractory to prior ibrutinib treatment, and 1 had received 5 prior lines of rituximab-based therapy.

She also noted that the DLBCL patients had a median of 4 prior therapies, and 4 of these patients had non-GCB DLBCL, including the only patient who responded to the triplet.

“[T]he combination of ublituximab, umbralisib, and ibrutinib in advanced CLL and NHL demonstrated a favorable toxicity profile as well as favorable efficacy,” Dr Nastoupil said in closing.

“[This] suggests umbralisib may be safely combined with other targeted agents to overcome mechanisms of resistance.”

Dr Nastoupil noted that 8 of the CLL patients had a 17p and/or 11q deletion, and 3 had previously received treatment with a BTK and/or PI3Kδ inhibitor.

One patient who was refractory to both idelalisib and ibrutinib achieved a CR with the triplet regimen, and this response has been ongoing for more than 1.5 years.

Among patients with NHL, the ORR was 100% in patients with MZL (2/2) and MCL (4/4). The ORR was 80% (4/5) in FL patients, and 17% (1/6) in DLBCL patients.

The CR rate was 50% in patients with MZL (1/2) and MCL (2/4) and 20% in patients with FL (1/5).

Dr Nastoupil pointed out that the FL patients were heavily pretreated. Two of them had received an autologous stem cell transplant, 1 was refractory to prior ibrutinib treatment, and 1 had received 5 prior lines of rituximab-based therapy.

She also noted that the DLBCL patients had a median of 4 prior therapies, and 4 of these patients had non-GCB DLBCL, including the only patient who responded to the triplet.

“[T]he combination of ublituximab, umbralisib, and ibrutinib in advanced CLL and NHL demonstrated a favorable toxicity profile as well as favorable efficacy,” Dr Nastoupil said in closing.

“[This] suggests umbralisib may be safely combined with other targeted agents to overcome mechanisms of resistance.” 

14th International Conference on Malignant Lymphoma (ICML)

LUGANO, SWITZERLAND—Interim results of a phase 2 trial suggest tazemetostat can be effective in patients with heavily pretreated, relapsed or refractory non-Hodgkin lymphoma.

The EZH2 inhibitor produced the highest overall response rate in patients with EZH2-mutated follicular lymphoma (FL), followed by EZH2-mutated diffuse large B-cell lymphoma (DLBCL).

However, the drug also produced complete responses in FL and DLBCL patients with wild-type EZH2.

“If we had focused [only] on patients with EZH2 mutations, we would have missed those other complete responders in the wild-type setting,” said study investigator Franck Morschhauser, MD, PhD, of Centre Hospitalier Régional Universitaire de Lille in France.

He presented results of the trial* during the plenary session of the 14th International Conference on Malignant Lymphoma (ICML). The research was sponsored by Epizyme, the company developing tazemetostat.

The trial enrolled patients with relapsed or refractory DLBCL or FL who had received at least 2 prior therapies. The patients received tazemetostat at 800 mg twice daily until disease progression or study withdrawal.

Efficacy in FL

Dr Morschhauser presented efficacy data on 67 patients with FL. Thirteen had EZH2 mutations, and 54 had wild-type EZH2. The median age was 62 in the mutated group and 61 in the wild-type group.

Both groups had a median of 4 prior lines of therapy. Fifty-four percent of EZH2-mutated patients were refractory to their last treatment, as were 48% of wild-type patients.

The median time from diagnosis was 7.4 years in mutated patients and 4.9 years in wild-type patients. The median time from last therapy was 13 weeks and 41.3 weeks, respectively.

The overall response rate was 92% (12/13) in EZH2-mutated patients and 26% (14/54) in wild-type patients. The complete response rates were 8% (n=1) and 6% (n=3), respectively.

The median time to first response was 11.9 weeks and 15.2 weeks, respectively.

None of the EZH2-mutated patients have progressed, but 13 (24%) wild-type patients have.

Forty-eight percent of all FL patients remain on study. One EZH2-mutated patient with stable disease is still on study, as are 23 wild-type patients with stable disease.

Efficacy in DLBCL

Dr Morschhauser presented data on 137 patients with DLBCL, 17 with EZH2 mutations and 120 with wild-type EZH2. The median age was 61 in the mutated group and 69 in the wild-type group.

Both groups had a median of 3 prior lines of therapy. Eighty-two percent of EZH2-mutated patients were refractory to their last treatment, as were 63% of wild-type patients.

The median time from diagnosis was 1 year in mutated patients and 2 years in wild-type patients. The median time from last therapy was 8.6 weeks and 11.6 weeks, respectively.

The overall response rate was 29% (5/17) in EZH2-mutated patients and 15% (18/119) in wild-type patients. The complete response rates were 0% (n=0) and 8% (n=10), respectively.

The median time to first response was 8.3 weeks and 8.5 weeks, respectively.

Six (35%) of the EZH2-mutated patients have progressed, as have 60 (50%) wild-type patients.

Twelve percent of all DLBCL patients remain on study. One EZH2-mutated patient with stable disease is still on therapy, as are 4 wild-type patients with stable disease.

Predictors of response

Dr Morschhauser and his colleagues performed next-generation sequencing of samples from 92 patients in an attempt to identify predictors of response to tazemetostat.

The data suggested that EZH2 and MYD88 activating mutations are positive predictors of response, and negative predictors include MYC, TP53, and HIST1H1E.

Safety

Safety data were available for 210 patients. The overall rate of treatment-related adverse events (AEs) was 59%, the rate of grade 3 or higher treatment-related AEs was 18%, and the rate of serious treatment-related AEs was 10%.

There were treatment-related AEs leading to dose interruption (15%), dose reduction (3%), and discontinuation of tazemetostat (2%).

The most common treatment-related AEs were nausea (14%), thrombocytopenia (13%), anemia (10%), neutropenia (9%), diarrhea (8%), asthenia (8%), and fatigue (7%).

Dr Morschhauser said these results “confirm that tazemetostat is quite safe” in this patient population, and enrollment in this trial is ongoing.

The European Commission (EC) has approved the Sandoz biosimilar rituximab (Rixathon^®) for use in the European Economic Area.

Rixathon is approved for all indications of the reference medicine, MabThera®, including follicular lymphoma, diffuse large B-cell lymphoma, chronic lymphocytic leukemia, and immunologic diseases such as rheumatoid arthritis, granulomatosis with polyangiitis, and microscopic polyangiitis.

This approval allows Rixathon to be marketed in the member states of the European Union and Iceland, Liechtenstein, and Norway, members of the European Free Trade Association.

The approval “represents a big win for patients in Europe with blood cancers or immunological diseases,” according to Carol Lynch, global head of Biopharmaceuticals at Sandoz.

“Rixathon will be one of the 5 major launches we plan in the next 4 years,” she said.

Earlier in the year, the European Medicines Agency’s Committee for Medicinal Products for Human Use had recommended marketing authorization for Rixathon.

The EC based its approval on a comprehensive development program generating analytical, preclinical, and clinical data.  Clinical studies included ASSIST-RA and ASSIST-FL.

ASSIST-RA demonstrated that the biosimilar product has equivalent pharmacokinetic and pharmacodynamic profiles to the reference medicine, with no clinically meaningful differences in safety, tolerability, or immunogenicity in patients with rheumatoid arthritis.

ASSIST-FL was a phase 3 study confirming efficacy and safety. The study met its primary endpoint of equivalence in overall response rate between the biosimilar product and the reference medicine after 6 months.

ASSIST-FL also confirmed the comparable safety profiles of the 2 medicines.

Sandoz is a division of the Swiss pharmaceutical company Novartis. MabThera is a registered trademark of F. Hoffmann-La-Roche AG.

Another Sandoz biosimilar rituximab has been approved in the EU as Riximyo® under a duplicate marketing authorization.

CHICAGO—The 15-year cumulative incidence of severe health conditions for survivors of childhood cancer has decreased over the past 30 years, from 12.7% for those diagnosed in the 1970s to 10.1% and 8.9% for those diagnosed in the 1980s and 1990s, respectively. And the decreases were greatest for patients with Wilms’ tumor and Hodgkin lymphoma (HL), followed by patients with astrocytoma, non-Hodgkin lymphoma (NHL), and acute lymphoblastic leukemia (ALL).

Investigators of the Childhood Cancer Survivor Study (CCSS) undertook a retrospective cohort analysis of children aged 0 – 14 years diagnosed with cancer between 1970 and 1999. Their goal was to determine whether cancer therapy modifications have maintained cure rates while decreasing the risk of late effects of therapy.

Todd M. Gibson, PhD, of St Jude Children’s Research Hospital in Memphis, Tennessee, presented the findings at the 2017 annual meeting of the American Society for Clinical Oncology (ASCO) as abstract LBA10500.

Researchers analyzed data from 23,600 childhood cancer survivors in the CCSS who were alive 5 years after diagnosis. The patients had leukemia, lymphoma, CNS malignancies, Wilms tumor, neuroblastoma, or soft-tissue/bone sarcoma.

Dr Gibson noted that while 83% of children with a malignancy achieve a 5-year survival, more than half develop at least one severe, disabling, life-threatening health condition by age 50.

The survivors were a median age at last follow-up of 28 years (range, 5-63) and the median time since diagnosis was 21 years (range, 5-43).

The investigators found significant decreases in severe health conditions in 6 diagnostic groups:

• Wilms tumor, decreased from 13% to 5% (P<0.0001)
• HL, decreased from 18% to 11% (P<0.0001)
• Astrocytoma, decreased from 15% to 9% (P=0.004)
• NHL, decreased from 10% to 6% (P=0.04)
• ALL, decreased from 9% to 7% (P=0.002)
• Ewings sarcoma, decreased from 19% to 10% (P=0.01)

They found no reductions in subsequent severe health conditions among survivors of neuroblastoma, acute myeloid leukemia (AML), soft tissue sarcoma, or osteosarcoma.

The investigators believe the decreases were driven mainly by a reduced incidence of endocrine conditions, subsequent malignant neoplasms, gastrointestinal and neurological conditions, but not cardiac or pulmonary conditions.

They also analyzed the reduction in treatment intensities by decade for different diseases and found they correlated with the reduced incidence of serious chronic health conditions by 15 years after diagnosis.

Diffuse large B-cell lymphoma

The US Food and Drug Administration (FDA) has accepted for priority review the biologics license application (BLA) for axicabtagene ciloleucel (formerly KTE-C19), a chimeric antigen receptor (CAR) T-cell therapy.

Kite Pharma, Inc. is seeking approval for axicabtagene ciloleucel as a treatment for patients with relapsed or refractory, aggressive non-Hodgkin lymphoma (NHL) who are ineligible for autologous stem cell transplant.

The FDA grants priority review to applications for products that may provide significant improvements in the treatment, diagnosis, or prevention of serious conditions.

The agency’s goal is to take action on a priority review application within 6 months of receiving it, rather than the standard 10 months.

The FDA has set a review deadline of November 29, 2017, for the axicabtagene ciloleucel BLA.

Axicabtagene ciloleucel also has breakthrough therapy designation from the FDA as a treatment for diffuse large B-cell lymphoma, transformed follicular lymphoma, and primary mediastinal B-cell lymphoma.

ZUMA-1 trial

The BLA for axicabtagene ciloleucel is supported by data from the phase 2 ZUMA-1 trial, which enrolled 111 patients with relapsed/refractory B-cell NHL.

After a single infusion of axicabtagene ciloleucel, the objective response rate was 82%. At a median follow-up of 8.7 months, 44% of patients were still in response, which included 39% of patients in complete response.

The most common grade 3 or higher adverse events were anemia (43%), neutropenia (39%), decreased neutrophil count (32%), febrile neutropenia (31%), decreased white blood cell count (29%), thrombocytopenia (24%), encephalopathy (21%), and decreased lymphocyte count (20%).

There were 3 deaths during the trial that were not due to disease progression. Two of these deaths were deemed related to axicabtagene ciloleucel.

Axicabtagene ciloleucel also has breakthrough therapy designation from the FDA as a treatment for diffuse large B-cell lymphoma, transformed follicular lymphoma, and primary mediastinal B-cell lymphoma.

ZUMA-1 trial

The BLA for axicabtagene ciloleucel is supported by data from the phase 2 ZUMA-1 trial, which enrolled 111 patients with relapsed/refractory B-cell NHL.

After a single infusion of axicabtagene ciloleucel, the objective response rate was 82%. At a median follow-up of 8.7 months, 44% of patients were still in response, which included 39% of patients in complete response.

The most common grade 3 or higher adverse events were anemia (43%), neutropenia (39%), decreased neutrophil count (32%), febrile neutropenia (31%), decreased white blood cell count (29%), thrombocytopenia (24%), encephalopathy (21%), and decreased lymphocyte count (20%).

There were 3 deaths during the trial that were not due to disease progression. Two of these deaths were deemed related to axicabtagene ciloleucel. 

Diffuse large B-cell lymphoma

The US Food and Drug Administration (FDA) has accepted for priority review the biologics license application (BLA) for axicabtagene ciloleucel (formerly KTE-C19), a chimeric antigen receptor (CAR) T-cell therapy.

Kite Pharma, Inc. is seeking approval for axicabtagene ciloleucel as a treatment for patients with relapsed or refractory, aggressive non-Hodgkin lymphoma (NHL) who are ineligible for autologous stem cell transplant.

The FDA grants priority review to applications for products that may provide significant improvements in the treatment, diagnosis, or prevention of serious conditions.

mycosis fungoides

The European Commission (EC) has granted orphan designation to MRG-106 for the treatment of cutaneous T-cell lymphoma (CTCL).

MRG-106 is a locked nucleic acid-modified oligonucleotide inhibitor of miR-155-5p.

miRagen Therapeutics, Inc., the company developing MRG-106, is currently testing the drug in a phase 1 trial of CTCL patients.

Early results from this trial were presented at the 2016 ASH Annual Meeting.

Researchers presented results in 6 patients with stage I-III mycosis fungoides.

The patients received 4 or 5 intratumoral injections of MRG-106 (at 75 mg) over 2 weeks. Four patients received saline injections in a second lesion on the same schedule.

There were 3 adverse events related to MRG-106—pain during injection, burning sensation during injection, and tingling at the injection site.

Adverse events considered possibly related to MRG-106 were pruritus, erythema, skin inflammation, sore on hand, nausea, decrease in white blood cells, neutropenia, and prolonged partial thromboplastin time.

One patient was taken off the trial due to rapid disease progression. The other 5 patients completed the dosing period.

All 5 patients had a reduction in the baseline Composite Assessment of Index Lesion Severity score in MRG-106-treated and saline-treated lesions.

The average maximal reduction was 55% (range, 33% to 77%) in MRG-106-treated lesions and 39% (range, 13% to 75%) in saline-treated lesions.

About orphan designation

Orphan designation provides regulatory and financial incentives for companies to develop and market therapies that treat life-threatening or chronically debilitating conditions affecting no more than 5 in 10,000 people in the European Union, and where no satisfactory treatment is available.

Orphan designation provides a 10-year period of marketing exclusivity if the drug receives regulatory approval.

The designation also provides incentives for companies seeking protocol assistance from the European Medicines Agency during the product development phase and direct access to the centralized authorization procedure.

The European Medicines Agency adopts an opinion on the granting of orphan drug designation, and that opinion is submitted to the EC for a final decision. The EC typically makes a decision within 30 days of that submission.

Follicular lymphoma

The US Food and Drug Administration (FDA) has granted priority review to the new drug application (NDA) for copanlisib, an intravenous PI3K inhibitor.

The NDA is for copanlisib as a treatment for patients with relapsed or refractory follicular lymphoma (FL) who have received at least 2 prior therapies.

The FDA grants priority review to applications for products that may provide significant improvements in the treatment, diagnosis, or prevention of serious conditions.

The agency’s goal is to take action on a priority review application within 6 months of receiving it, rather than the standard 10 months.

The application for copanlisib is supported by data from the CHRONOS-1 trial. This phase 2 trial enrolled 141 patients with relapsed/refractory, indolent non-Hodgkin lymphoma. Most of these patients had FL (n=104).

In all patients, copanlisib produced an objective response rate of 59.2%, with a complete response rate of 12%. The median duration of response exceeded 98 weeks.

In the FL subset, copanlisib produced an overall response rate of 58.7%, with a complete response rate of 14.4%. The median duration of response exceeded 52 weeks.

In the entire cohort, there were 3 deaths considered related to copanlisib.

The most common treatment-related adverse events were transient hyperglycemia (all grades: 49%/grade 3-4: 40%) and hypertension (all grades: 29%/grade 3: 23%).

“Patients with relapsed or refractory follicular lymphoma have a poor prognosis, and new treatment options which are well tolerated and effective are needed to prolong progression-free survival and improve quality of life for these patients,” said Martin Dreyling, MD, a professor at the University of Munich Hospital (Grosshadern) in Germany and lead investigator of the CHRONOS-1 study.

“Based on the CHRONOS-1 results, where copanlisib showed durable efficacy with a manageable and distinct safety profile, the compound may have the potential to address this unmet medical need.”

Data from CHRONOS-1 were presented at the AACR Annual Meeting 2017.

Data from the FL subset of the trial are scheduled to be presented at the 2017 ASCO Annual Meeting in June.

Copanlisib is being developed by Bayer. The compound has fast track and orphan drug designations from the FDA.

The FDA grants orphan designation to products 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 product is approved.

The FDA’s fast track program is designed to facilitate the development and expedite the review of products intended to treat or prevent serious or life-threatening conditions and address unmet medical need.

Through the fast track program, a product may be eligible for priority review. In addition, the company developing the product may be allowed to submit sections of the NDA or biologic license application on a rolling basis as data become available.

Fast track designation also provides the company with opportunities for more frequent meetings and written communications with the FDA.

Lab mouse

A nucleoside analog has shown potential for treating primary effusion lymphoma (PEL) and multiple myeloma (MM), according to researchers.

The compound, 6-ethylthioinosine (6-ETI), killed both PEL and MM cells in vitro.

6-ETI also reduced tumor burden and prolonged survival in mouse models of MM and PEL.

Ethel Cesarman, MD, PhD, of Weill Cornell Medicine in New York, New York, and her colleagues conducted this research and disclosed their results in the Journal of Clinical Investigation.

The researchers identified 6-ETI via high-throughput screening, and they initially tested the compound in PEL cell lines. 6-ETI induced necrosis, apoptosis, and autophagy in these cells.

In a xenograft model of PEL, mice treated with 6-ETI experienced “striking and immediate regression of the implanted xenograft within 3 days of treatment,” according to the researchers.

In addition, mice that received 6-ETI had significantly longer progression-free and overall survival than control mice (P<0.0001 for both), and the researchers said there were no obvious toxicities from the treatment.

Looking into the mechanism of 6-ETI, the researchers found that adenosine kinase (ADK) is required to phosphorylate and activate the compound, and PEL cells have high levels of ADK.

Because PEL cells closely resemble plasma cells, the researchers theorized that MM might produce high levels of ADK as well. Experiments in MM cells proved this theory correct.

So the researchers tested 6-ETI in MM cell lines and samples from MM patients. The compound induced apoptosis and autophagy, and it activated a DNA damage response in MM cells.

In a mouse model of MM, 6-ETI treatment significantly reduced tumor burden but did not result in weight loss. And treated mice had significantly longer overall survival than control mice (P<0.005).

Dr Cesarman and her colleagues are now trying to better understand how 6-ETI works and determine what other cancers expressing high levels of ADK might respond to the drug.

“This compound could provide a much-needed approach to treat people with some forms of plasma malignancies as well as other cancers that express ADK,” Dr Cesarman said.
