"We are thrilled with the continued progress in our alliance with Bristol-Myers Squibb that has included two new target selections this year and the recent presentations of strong preclinical proof-of-concept data for our anti-CTLA-4 Probody therapeutic program at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Symposium on Immuno-Oncology and the Society for Immunotherapy in Cancer (SITC) (Free SITC Whitepaper) Annual Meeting," said Sean McCarthy, D.Phil., president and chief executive officer of CytomX Therapeutics. "We look forward to continued progress in each of these collaboration programs as we pursue our vision of transforming lives with safer, more effective therapies."

Investigational therapeutics developed with CytomX’s Probody platform are designed to be active in the tumor while sparing healthy tissue. By restricting activity to the tumor microenvironment, investigational Probody therapeutics directed against both validated and novel targets have been shown preclinically to enable anti-tumor efficacy with an enhanced safety window, relative to traditional antibody-based therapies.

About the Collaboration Agreement
Under the terms of the agreement, which was entered into in May of 2014, CytomX granted Bristol-Myers Squibb exclusive worldwide rights to develop and commercialize Probody therapeutics for up to four oncology targets. Bristol-Myers Squibb made an upfront payment of $50 million to CytomX in 2014, and provides research funding over the course of the research term. Upon the selection of the third and fourth targets, Bristol-Myers Squibb pays CytomX selection payments. CytomX is also eligible to receive additional preclinical payments and up to $298 million in future development, regulatory and sales milestone payments for each collaboration target, as well as tiered royalties rising from mid-single digit to low double digits on net sales of each product commercialized by Bristol-Myers Squibb.

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.

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."

ARIAD Presents Updated Brigatinib Data with 18.4 Months Median Intracranial Progression Free Survival (PFS) in ALK+ NSCLC Patients with CNS Metastases at the World Conference on Lung Cancer

On December 5, 2016 ARIAD Pharmaceuticals, Inc. (NASDAQ: ARIA), a rare cancer-focused innovative biotechnology company, reported clinical data on brigatinib, its investigational anaplastic lymphoma kinase (ALK) inhibitor, from the ongoing Phase 1/2 and pivotal ALTA trials in patients with ALK-positive (ALK+) non-small cell lung cancer (NSCLC) and intracranial central nervous system (CNS) metastases (Press release, Ariad, DEC 5, 2016, View Source;p=RssLanding&cat=news&id=2227425 [SID1234516925]). These data, being presented today at the International Association for the Study of Lung Cancer (IASLC) 17th World Conference on Lung Cancer (WCLC) being held in Vienna, showed that in patients with measurable brain metastases, the confirmed intracranial objective response rate (ORR) was 53 percent in the Phase 1/2 trial, and the confirmed intracranial ORR was 67 percent in Arm B (brigatinib 180 mg with seven-day lead-in at 90 mg once daily) in the ALTA trial. Median intracranial progression-free survival (PFS) in ALTA Arm B was 18.4 months.

"Although crizotinib is initially effective in most patients with advanced ALK rearranged lung cancer, patients eventually develop resistance to crizotinib, often with new or progressive brain metastases," said presenting author Scott N. Gettinger, M.D., associate professor of medicine at Yale Cancer Center. "We are clearly encouraged by these data that demonstrate efficacy in the brain, with median intracranial PFS of over one and a half years, in patients with crizotinib refractory disease."

The ALTA Trial

The ALTA (ALK in Lung Cancer Trial of AP26113) trial enrolled 222 patients with ALK+ NSCLC who had been treated with and experienced disease progression on their most recent crizotinib therapy. Patients were randomized one-to-one to receive either 90 mg of brigatinib once per day (QD) (Arm A), or 180 mg QD with a seven-day lead-in at 90 mg QD (Arm B). In addition, patients were stratified by presence of brain metastases at baseline and best response to prior crizotinib therapy. Patient enrollment is complete, with the last patient enrolled in September 2015. Median follow-up in all patients with intracranial CNS metastases at baseline enrolled in the ALTA trial was 10.7 months as of May 31, 2016.

Phase 1/2 Study

The Phase 1/2 study of brigatinib included a dose-escalation portion that enrolled patients with advanced solid tumors, particularly those with NSCLC, who were either refractory to available therapies or had no standard treatment available to them. The Phase 2 portion of the trial includes five expansion cohorts. The trial enrolled 137 patients with 79 patients having ALK+ NSCLC. All but eight ALK+ NSCLC patients had failed prior crizotinib therapy. Patient enrollment in the trial is complete, with the last patient enrolled in July 2014. Median follow-up in ALK+ NSCLC patients with intracranial CNS metastases at baseline in the Phase 1/2 study was 24.9 months as of May 31, 2016.

Key Data from Oral Presentation on Patients with Baseline CNS Metastases from Phase 1/2 and ALTA Trials

Follow-up Data as of May 31, 2016; Last IRC Data in ALTA Trial was July 13, 2016, and Last Brain Scan in Phase 1/2 Trial was October 8, 2015

In the Phase 1/2 trial of brigatinib, 50/79 (63%) of ALK+ NSCLC patients had IRC-assessed baseline brain metastases. In the ALTA trial, 153/222 (69%) of ALK+ NSCLC patients had IRC-assessed baseline brain metastases. The efficacy analysis of Phase 1/2 trial data was based on an evaluable population (patients with at least one on-study brain scan, n=46), and the analysis of ALTA trial data was based on the intention-to-treat (ITT) population (n=153).
As of May 31, 2016, 42 percent and 55 percent of ALK+ NSCLC patients with brain metastases at baseline remained on study in the Phase 1/2 and ALTA populations respectively.
For patients with measurable brain lesions, the confirmed intracranial ORR was 53 percent (8/15) in the Phase 1/2 trial, and confirmed intracranial ORRs were 67 percent (12/18) in Arm B and 46 percent (12/26) in Arm A in the ALTA trial.
There were 31 patients in the Phase 1/2 trial with only non-measurable brain lesions, and of these, 35 percent had complete resolution of lesions. In ALTA, there were 55 patients in Arm B and 54 in Arm A with only non-measurable lesions; of these, 18 percent and seven percent of patients, respectively, had complete resolution of lesions.
For patients with any brain metastases at baseline:
Median duration of intracranial response in confirmed responders was 11.4 months in the Phase 1/2 trial (n=19); and was not yet reached in either arm of the ALTA trial (n=22 in Arm B and n=16 in Arm A).
Median intracranial PFS was 14.6 months in the Phase 1/2 trial (n=46); and 18.4 months (95% confidence interval [CI] 12.8 – not reached) and 15.6 months (95% CI 9.0-18.3 months) in ALTA Arm B and Arm A, respectively (n=73/n=80).
In the Phase 1/2 trial (n=46), for patients with any brain metastases at baseline, investigator-assessed whole-body ORR was 74 percent, median duration of response was 24 months and median PFS was 14.5 months. In ALTA (Arms B and A, respectively), for patients with any brain metastases at baseline, investigator-assessed whole-body ORR was 58 percent and 39 percent, median duration of response was not yet reached and 12 months, and median PFS was 12.9 months and 9.2 months.
In patients with any brain metastases at baseline in the ALTA trial, the most common treatment-emergent adverse events (AEs), grade 3 or higher (excluding neoplasm progression), were (n=151 treated; Arm B/A): increased creatine phosphokinase (CPK) (12%/1%), hypertension (7%/4%), increased lipase (3%/4%), malignant pleural effusion (1%/4%) and pneumonia (4%/1%).
The oral presentation, "Brigatinib Activity in Patients with ALK+ NSCLC and Intracranial CNS Metastases in Two Clinical Trials," (Abstract #4374, Oral ID OA08.06) will be presented today, Monday, December 5, 2016 in the Schubert 1 Auditorium at 11:57 am ET/16:57 GMT.

About Brigatinib

Brigatinib is an investigational, targeted cancer medicine discovered internally at ARIAD. Brigatinib received Breakthrough Therapy designation from the FDA for the treatment of patients with ALK+ NSCLC whose tumors are resistant to crizotinib, and was granted orphan drug designation by the FDA for the treatment of ALK+ NSCLC. The FDA has accepted brigatinib’s New Drug Application based on data from an earlier datacut, and has granted ARIAD’s request for Priority Review. The FDA has set an action date of April 29, 2017 under the Prescription Drug User Fee Act (PDUFA). ARIAD intends to submit a Marketing Authorization Application (MAA) for brigatinib to the European Medicines Agency (EMA) in early 2017, based on this datacut.

ARIAD has also initiated the Phase 3 ALTA 1L trial to assess the efficacy and safety of brigatinib in comparison to crizotinib in patients with locally advanced or metastatic ALK+ NSCLC who have not received prior treatment with an ALK inhibitor. More information on brigatinib clinical trials, as well as the expanded access program (EAP) for ALK+ NSCLC can be found here.
