Continued long-lasting responses of more than 26 months reported in patients with relapsed/refractory NHL in a phase 2a trial with MOR208 monotherapy

An oral presentation reported data from a phase 2a study evaluating single-agent MOR208 in 92 patients with various subtypes of relapsed or refractory non-Hodgkin’s lymphoma (NHL) including diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL) and other indolent NHL (iNHL). Results were consistent with prior updates from the study, reflecting in particular a continuation of long-lasting responses of more than 26 months.

"Patients with NHL, who are refractory or show relapse after previous anti-CD20-based therapies, have limited treatment alternatives and usually a very poor prognosis. These updated results illustrate our ongoing efforts to develop MOR208 as a potential new CD19-based antibody therapy for patients suffering from B-cell malignancies, including DLBCL, in phase 2 studies in combination with other cancer drugs," said Dr. Arndt Schottelius, Chief Development Officer of MorphoSys AG.

At the last cutoff date, June 3, 2016, three patients with DLBCL and six with iNHL were in remission and on study treatment, with the longest responses in both subgroups ongoing for more than 26 months. Of these nine patients, seven showed complete responses and 2 experienced partial responses. The median duration of response was 20.1 months for DLBCL and not yet reached for iNHL. The overall response rate (ORR), based on complete responses (CR) and partial responses (PR), was 36% in the DLBCL subgroup and 33% in iNHL patients (both based on evaluable patients). Based on all patients with DLBCL and iNHL in the study, the ORR was 26% and 29%, respectively. The progression free survival (PFS) rate at 12 months was 39% in both subgroups. In addition to the patients with an objective response (PR or CR), the majority of patients with stable disease (SD) (5/6 DLBCL and 14/17 iNHL) had a reduction in target lesion size (central assessment).

PFS was similar in patients with rituximab non-refractory versus rituximab refractory tumors. Fifty-two patients (57%) in the study were classified as having rituximab refractory disease. Of those, five of 24 patients (21%) with DLBCL and five of 22 patients (23%) with iNHL responded to MOR208. Of the 10 responders with rituximab refractory disease, six had a response duration longer than 10 months, two of which lasted for more than 26 months.

The most common adverse events were infusion-related reactions (IRRs) occurring in 12% of the patients (11% of grade 1 or 2, 1% of grade 4) and neutropenia occurring in 12% of patients (3% of grade 1 or 2, 9% of grade 3 or higher). No treatment-related deaths were reported.

Abstract #623
Jurczak et al: Single-Agent MOR208 in Relapsed or Refractory (R-R) Non-Hodgkin’s Lymphoma (NHL): Results from Diffuse Large B-Cell Lymphoma (DLBCL) and Indolent NHL Subgroups of a Phase IIa Study

Combination of MOR208 with lenalidomide and ibrutinib in CLL from phase 2 investigator-initiated trial

A second presentation is a poster from investigators at The Ohio State University, who reported on an investigator-initiated trial (IIT) evaluating MOR208 in combination with lenalidomide in three cohorts of patients with chronic lymphatic leukemia (CLL): previously untreated CLL patients, relapsed/refractory CLL patients; and patients with Richter’s Transformation.

The trial also included a 4th cohort of ibrutinib-treated CLL patients with identified resistance mutations to ibrutinib in the tumors (molecular relapse) but no confirmed clinical relapse where MOR208 was added to ibrutinib therapy. Recent data have generally shown poor clinical outcomes in patients who relapse after a therapy with the BTK inhibitor ibrutinib and whose leukemia cells carry a mutation in the BTK gene prior to relapse.

According to the data presented, 34 patients have been enrolled in the study so far, 27 receiving MOR208 in combination with lenalidomide (11 of which in the previously untreated cohort, 11 in the relapsed/refractory cohort, 5 in the Richter’s Transformation cohort) and 7 receiving MOR208 plus ibrutinib, with patient accrual still ongoing.

Most frequent hematological adverse event over all cohorts were thrombocytopenia in 47% of patients (9% grade 3 or higher) and neutropenia in 35% (21% grade 3 or higher). There were no unexpected serious adverse events reported.

According to the abstract, in the group of CLL patients with ibrutinib-resistant cells receiving MOR208 in addition to ibrutinib, four out of seven patients have been on study for at least 3 cycles of 28 days each already, and no patient had developed progressive disease at the time of abstract data cut-off. Preliminary activity has been seen in all cohorts, including ibrutinib-resistant CLL patients.

"There is a high unmet medical need for CLL patients, especially those showing resistance to ibrutinib therapy," said Dr. Jennifer Woyach, Assistant Professor of Internal Medicine at Ohio State University. "Therefore we added an additional cohort to our ongoing CLL study to evaluate MOR208 in combination with ibrutinib in order to investigate whether MOR208 could be a promising combination partner in this setting. We are looking forward to the continuation of the trial and to present further results going forward."

On December 5, 2016 Actinium Pharmaceuticals, Inc. (NYSE MKT:ATNM) ("Actinium" or "the Company"), a biopharmaceutical company developing innovative targeted therapies for cancers lacking effective treatment options, reported that results from its Phase 1 trial of Actimab-A were presented at the 58th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting (ASH) (Free ASH Whitepaper) that is currently ongoing in San Diego, CA (Press release, Actinium Pharmaceuticals, DEC 5, 2016, View Source [SID1234516965]). Data from the previously conducted Phase 1 study pertaining to safety, efficacy and PB burden were highlighted during the poster session. Actimab-A is currently being studied in a 53-patient Phase 2 clinical trial as a monotherapy for patients newly diagnosed with Acute Myeloid Leukemia (AML) age 60 and above who are ineligible for currently used induction therapies. The Phase 2 trial is studying Actimab-A as a monotherapy administered via two fifteen minute intravenous injections of 2.0 μCi/kg/fraction of Actimab-A given a week apart. PB burden below 200 blasts/µL will serve as an inclusion criteria and patients above this threshold will be administered hydroxyurea to reduce their peripheral blasts counts prior to Actimab-A administration. Results from the Phase 1 trial showed that patients with PB burden below 200 blasts/µL who received a dose of 2.0 μCi/kg/fraction of Actimab-A saw a 50% response rate.

Actinium’s PB burden hypothesis states that patients below the key threshold level of 200 blasts/µL have an increased response rate to Actimab-A while patients above the key threshold are unlikely to respond. An analysis of 2 clinical trials with Actimab-A totaling 38 patients, of which 36 were evaluable, showed that 42% (8 of 19) of patients with blasts counts below 200/µL responded to Actimab-A while no patients with blast counts above 200/µL responded to Actimab-A. The Phase 1 trial was a dose escalation study using a 3+3 design. Dose escalation proceeded if dose-limiting toxicities (DLT) were seen in less than 33% of patients. Maximum tolerable dose (MTD) was not reached in the Phase 1 trial.

Dr. Joseph Jurcic, Director of Hematologic Malignancies and Professor of Medicine at Columbia University Medical Center and Principal Investigator of the study said, "Older patients with AML, particularly those that have progressed from MDS, are difficult to treat and have very few treatment options since many have already received lower-intensity therapy with hypomethylating agents. The results from this Phase 1 trial were encouraging in regards to both the safety and efficacy of Actimab-A. We are particularly excited to have identified that patients with peripheral blasts below 200/µL have higher response rates to Actimab-A and that we can reduce blast counts in patients above that level using hydroxyurea. Actimab-A has shown promise in older AML patients, including those previously treated for MDS–a population excluded from trials with most novel agents, including ongoing studies with other CD33-directed therapies. We look forward to continuing to study Actimab-A in the ongoing Phase 2 trial and potentially meeting this critical need."

Of the 18 patients in the Phase 1 trial, 28% (5 of 18) had objective responses (2 CR, 1CRp and 2 CRi). Amongst patients with objective responses, median response duration was 9.1 months (range, 4.1-16.9 months). At the 3 highest dose levels in the Phase 1 trial (1.0 μCi/kg/fraction – 2.0 μCi/kg/fraction) objective responses were seen in 33% of patients (5 of 15). Mean bone marrow blast reduction amongst evaluable patients was 66% with 57% of patients having bone marrow blast reduction of 50% or greater and 79% of patients (11 of 14) had bone marrow blast reductions after Cycle 1 of therapy. The Phase 1 trial enrolled patients newly diagnosed with AML who are age 60 and above who were administered Actimab-A in combination with low-dose Cytarabine. Median patient age was 77 with 67% of patients having prior myelodysplastic syndrome (MDS) of which, 83% received prior therapy consisting of either hypomethylating agents (HMAs) or a hematopoietic stem cell transplant (HSCT).

A formal interim analysis will occur after 31 patients receive Actimab-A, which the Company expects to occur in mid-2017. The Company anticipates the Phase 2 trial to be complete by the end of 2017.

"Actimab-A, given its benign toxicity profile combined with potent efficacy as evidenced by the results presented today along with its ease of administration via 2 injections, represents an exciting therapy for elderly patients with AML," said Sandesh Seth, Executive Chairman of Actinium. "Due to our peripheral blast burden hypothesis and optimized Phase 2 protocol we have great excitement for the current Phase 2 clinical trial and future development pathways for Actimab-A."

About Actimab-A

Actimab-A, Actinium’s most advanced alpha particle immunotherapy (APIT) product candidate, is currently in a 53-patient, multicenter Phase 2 trial for patients newly diagnosed with AML age 60 and above. Actimab-A is being developed as a first-line therapy and is a monotherapy that is administered via two 15-minute injections that are given 7 days apart. Actimab-A targets CD33, a protein abundantly expressed on the surface of AML cells via the monoclonal antibody, HuM195, which carries the potent cytotoxic radioisotope actinium-225 to the AML cancer calls. Actinium-225 gives off high-energy alpha particles as it decays, which kill cancer cells and as actinium-225 decays it produces a series of daughter atoms, each of which gives off its own alpha particle, increasing the chances that the cancer cell will be destroyed. Actimab-A is a second-generation therapy from the Company’s HuM195-Alpha program, which was developed at Memorial Sloan Kettering Cancer Center and has now been studied in almost 90 patients in four clinical trials. Actimab-A has been granted Orphan Drug Designation for newly diagnosed AML age 60 and above

On December 5, 2016 Sunesis Pharmaceuticals, Inc. (Nasdaq:SNSS) reported the presentation of updated results from the VALOR trial examining overall survival in patients age 60 years and older with relapsed/refractory AML (Press release, Sunesis, DEC 5, 2016, View Source;p=RssLanding&cat=news&id=2227712 [SID1234516964]). The results are being presented today at 3:15 PM PT in an oral session titled "Acute Myeloid Leukemia: Novel Therapy, excluding Transplantation: Clinical trials of Novel Drugs and Combinations in AML" taking place from 2:45 PM – 5:45 PM PT at the 58th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting in San Diego, California. The presentation (abstract 903, Marriott Marquis San Diego Marina, Ballroom AB), titled "Durable Overall Survival Benefit in Patients ≥ 60 Years with Relapsed or Refractory AML Treated with Vosaroxin/Cytarabine Vs Placebo/Cytarabine: Updated Results from the Valor Trial," is available at www.sunesis.com.

"Clinical outcomes among patients with relapsed/refractory AML remain abysmal, particularly among older patients," said Farhad Ravandi, M.D., Professor of Medicine, Department of Leukemia, University of Texas MD Anderson Cancer Center, and a principal investigator of the VALOR study. "Results from the updated survival data from VALOR and the post-hoc analyses presented today, show compelling durable survival outcomes among older patients, and support the use of vosaroxin, in combination with cytarabine, as an important treatment option for this group of AML patients desperately in need of new therapies."

VALOR is a randomized, double-blind, placebo-controlled Phase 3 trial that enrolled 711 adult patients with first relapsed or refractory AML at 124 sites in 15 countries. Patients were stratified for age, geographic region and disease status and randomized one to one to receive either vosaroxin and cytarabine or placebo and cytarabine. At the time of the primary analysis in October 2014, the overall survival (OS) was significantly improved with vosaroxin/cytarabine versus placebo/cytarabine in patients age 60 years and older (7.1 months vs 5.0 months, HR=0.75, p=0.0030), with a complete remission (CR) rate of (31.9% vs 13.8%, p < 0.0001).

The new data presented today from the VALOR trial include an updated survival analysis in the 451 patient subset age 60 and older, sensitivity analyses of OS in patients age 60 and older, and analyses examining the differences in treatment effect by age. The results demonstrate that, after a median of 39.9 months of follow-up, OS for patients age 60 years and older remains significantly improved for the vosaroxin/cytarabine arm compared to the placebo/cytarabine arm (figure 1), with survival curves remaining separated through 48 months.

A graph accompanying this announcement is available at View Source

Treatment Arm Patients, n Events, n (%) Censored, n (%) Median OS (95% CI) P value (2-sided)
Pla+Cyt 225 212 (94.2%) 13 (5.8%) 5.0 (3.8-6.4) 0.0017
Vos+Cyt 226 199 (88.1%) 27 (11.9%) 7.1 (5.8-8.1)
Of note, twice as many patients were alive on the vosaroxin-containing arm at both the 24 and 36 months’ time points highlighting the durability of benefit observed in this patient group.

An OS benefit with the addition of vosaroxin was observed consistently across smaller subgroups above 60 years (figure 2). Smaller age groups below 60 years did not demonstrate a similar OS benefit.

Figure 2.

Median OS, months
Patent Age Vosaroxin/Cytarabine Placebo/Cytarabine Hazard Ratio (95% CI)
60-64 years (n = 124) 8.1 5.2 0.72 (0.49-1.06)
65-74 years (n = 293) 7.0 5.0 0.76 (0.60-0.97)
75-84 years (n = 34) 5.5 3.3 0.72 (0.36-1.45)
Sunesis also performed a multivariate survival analysis adjusting for baseline prognostic factors. In this analysis, the HR for OS in the ITT population was 0.80 (p=0.0114) and for patients age 60 and older the OS HR was 0.68 (p=0.0004).

"All of these data and analyses further underscore the consistency, durability and robustness of the survival benefit for patients age 60 years and older who received vosaroxin in the VALOR study," said Daniel Swisher, President and Chief Executive Officer of Sunesis. "As we work toward a European regulatory decision for vosaroxin in this patient population, we remain committed to making vosaroxin available as a new treatment option for underserved patients with relapsed refractory AML. As our regulatory efforts progress, we also continue to advance active dialogues with potential pharma collaborators toward the goal of supporting a European market launch in 2017."

About QINPREZO (vosaroxin)

QINPREZO (vosaroxin) is an anti-cancer quinolone derivative (AQD), a class of compounds that has not been used previously for the treatment of cancer. Preclinical data demonstrate that vosaroxin both intercalates DNA and inhibits topoisomerase II, resulting in replication-dependent, site-selective DNA damage, G2 arrest and apoptosis. Both the U.S. Food and Drug Administration (FDA) and European Commission have granted orphan drug designation to vosaroxin for the treatment of AML. Vosaroxin is an investigational drug that has not been approved for use in any jurisdiction.

Vosaroxin’s Marketing Authorization Application for relapsed refractory AML is currently under review by the European Medicines Agency, and a regulatory decision regarding approval is expected in 2017.

The trademark name QINPREZO is conditionally accepted by the FDA and the EMA as the proprietary name for the vosaroxin drug product candidate.

"The results presented include updated data from higher dosing cohorts of MOR202 in combination with IMiDs, in patients being evaluable for efficacy and safety assessment. In addition to the infusion time of 2 hours and the occurrence of infusion-related reactions in only 7% of the patients, we are particularly pleased with the responses seen in patients treated with MOR202 plus Len/Dex and Pom/Dex", Dr. Arndt Schottelius, Chief Development Officer of MorphoSys AG, commented. "We look forward to enrolling more patients in the highest dosing cohorts of 16 mg/kg MOR202 in these combinations."

Patients treated with MOR202 in combination with Len/Dex had a median of 2 prior regimens; 64% were refractory to their last therapy. In this arm of the trial, 91% of evaluable patients (10 out of 11) showed an objective response (defined as either a complete response (CR) or a partial response (PR)) to MOR202 and Len/Dex. Considering only patients in the highest dosing cohort of 16mg/kg MOR202 plus Len, ORR (objective response rate) was 100%, with 7 out of 7 patients showing response to treatment.

In the group receiving MOR202 with Pom/Dex, patients had a median of 3 prior therapies, all being refractory to their last therapy. In these heavily pretreated patients, 57% (4 out of 7) showed a response, with two patients achieving a complete remission (CR). In relapsed/refractory patients treated with MOR202 alone, 29% (5 out of 17) showed an objective response.

Responses are ongoing in 16 of 19 patients, with the longest response ongoing for more than 14 months. The median progression-free survival (PFS) of the patients treated with MOR202 alone was 4.7 months; the median PFS for the combination regimen has not yet been reached.

MOR202 was given as a 2-hour infusion up to the highest dose of 16 mg/kg. Infusion-related reactions (IRRs) occurred in 7% of patients and were limited to grade 1 or 2. The most frequent adverse events of grade 3 or higher were lymphopenia, neutropenia and leukopenia. No unexpected safety signals were observed. No treatment-related deaths were reported.

According to a biomarker analysis, CD38 molecules were preserved on bone marrow plasma cells during MOR202 treatment, comparing values at baseline and at cycle 2 day 1.

About MOR202 and the ongoing phase 1/2a study in multiple myeloma
The investigational drug MOR202 is a fully human HuCAL antibody targeting CD38, a highly expressed and validated target in multiple myeloma. Data are from an ongoing clinical phase 1/2a, open-label, multi-center, dose-escalation study conducted in several sites in Germany and Austria. The study is evaluating the safety and preliminary efficacy of MOR202 alone and in combination with the immunomodulatory drugs pomalidomide (Pom) and lenalidomide (Len) plus dexamethasone (Dex) in patients with relapsed/refractory multiple myeloma. The primary endpoints of the trial are the safety, tolerability and recommended dose of MOR202 alone and in combination with the IMiDs. Secondary outcome measures are pharmacokinetics and preliminary efficacy based on overall response rate, duration of response, time-to-progression, and progression-free survival.
