On November 19, 2014 BIND Therapeutics reported positive results from its ongoing Phase 2 study of BIND-014 in non-small cell lung cancer (NSCLC), demonstrating it has met the primary objective in the once every three weeks (Q3W) arm as measured by overall response rate (ORR) (Press release BIND Therapeutics, NOV 19, 2014, View Source [SID:1234500985]). The data demonstrate that BIND-014 is well-tolerated with clinically meaningful anti-tumor activity at a lower dose than conventional docetaxel in patients with advanced or metastatic NSCLC. BIND-014 also demonstrates promising anti-tumor activity in patients with tumors expressing KRAS mutations (mutated Kirsten ras oncogene homolog). KRAS mutations in NSCLC are generally associated with poor response to currently available drug therapy regimens, including docetaxel. An additional signal was observed in patients with squamous cell carcinomas, a major NSCLC subtype poorly served by existing available therapies. These data were presented at the 26th EORTC-NCI-AACR (Free EORTC-NCI-AACR Whitepaper) Symposium on Molecular Targets and Cancer Therapeutics in Barcelona, Spain.

"We believe the activity and tolerability of BIND-014 demonstrated in this study suggest meaningful differentiation from the historical docetaxel experience, in both the broader NSCLC patient population and in two important groups of patients with high unmet medical need," said Hagop Youssoufian, M.D., M.Sc., Chief Medical Officer, BIND Therapeutics. "Furthermore, as the first product candidate from our Medicinal Nanoengineering platform to enter the clinic, we believe that the increased efficacy and reduced toxicity at a lower dose compared to historical docetaxel experience suggests that Accurins are successful in targeting the therapeutic payload to the tumor. Based on these positive results, we plan to conduct additional global, multicenter Phase 2 studies to confirm and expand the dataset on BIND-014 and to define an expeditious regulatory path for BIND-014."

The Q3W dosing arm of the open label, multicenter, Phase 2 study enrolled 40 patients with advanced metastatic NSCLC who were treated with 60 mg/m2 of BIND-014 on Day 1 of a 21-day cycle and achieved the following preliminary results:

Five patients (13%, N=40) achieved a partial response with a median duration of response of 5.2 months and median progression free survival (PFS) of 2.7 months. There was one unconfirmed partial response that was not included in the analysis per RECIST v1.1.
Nine patients were enrolled with a confirmed KRAS mutation and two of those nine experienced an objective response (22%); median PFS in patients with KRAS mutant tumors was 2.7 months.
In patients with squamous cell carcinoma (n=9) there were no confirmed objective responses; however, median PFS in patients with squamous cell carcinoma was 2.8 months. Prolonged ( > 4 cycles) disease control was also noted in six of nine (66%) patients with squamous histology.
Preliminary median overall survival was 6.2 months for all patients treated, 9.6 months in patients with KRAS mutant tumors and 11.1 months in patients with squamous cell carcinoma.
Twenty-one of 40 patients received four or more cycles of therapy, attesting to the tolerability of BIND-014. Consistent with previous results, neutropenia, anemia, neuropathy, and alopecia, commonly observed with docetaxel, were significantly reduced with BIND-014.

"Data from this open label study suggest the potential for BIND-014 superiority over docetaxel in the treatment of NSCLC patients," said Ronald B. Natale, M.D., Medical Director of the Clinical Lung Cancer Program at the Women’s Guild Lung Institute and investigator for the Phase 2 trial of BIND-014 in NSCLC. "Furthermore, BIND-014 demonstrated intriguing activity in patients with KRAS mutated lung cancers, a group of patients who have historically been unresponsive to standard treatment with docetaxel. This initial experience with BIND-014 provides a glimpse into a new way to selectively target NSCLC tumors, an area of cancer with high unmet need."

BIND plans to initiate global, multicenter Phase 2 studies of BIND-014 in patients with KRAS mutant NSCLC and in patients with NSCLC of squamous histology who have progressed on prior therapy. These studies aim to assess overall survival and additional endpoints to position BIND-014 for subsequent registration studies.

Based on the promising results of the Q3W arm presented today and the more patient-friendly once every three week dosing schedule, combined with the absence of a confirmed partial response in the first 22 patients enrolled on the Q1W schedule, the company will not continue enrollment on the weekly dosing schedule.

Data from the Phase 2 study will be included in a presentation by BIND CEO Scott Minick at the Stifel Nicolaus Weisel Healthcare Conference in New York at 8:35 a.m. EST today. Interested parties may access a live webcast of the presentation by visiting the BIND Therapeutics website at www.bindtherapeutics.com. The webcast will be archived on the BIND Therapeutics website following the event for one week.

On November 19, 2014 Sunesis Pharmaceuticals reported the online publication of results from the Company’s Phase 1b/2 study of vosaroxin in combination with cytarabine in patients with relapsed or refractory acute myeloid leukemia (AML) in the November 7, 2014 Ahead of Print issue of Haematologica (Press release Sunesis, NOV 19, 2014, View Source;p=RssLanding&cat=news&id=1991012 [SID:1234500984]).

"Acute myeloid leukemia is a complex, genetically heterogeneous cancer for which there has been no advancement in drug treatment in over 40 years," stated Dr. Jeffrey Lancet, Senior Member and Professor of Oncologic Sciences at the H. Lee Moffitt Cancer Center, Tampa, Florida and lead author of the publication. "In this study, we see that vosaroxin, in combination with cytarabine, is active and well tolerated. These results were mirrored in the Phase 3 VALOR trial, which demonstrated clinically meaningful outcomes supported by encouraging response rates and a manageable safety profile.

The Phase 1b/2 study assessed the safety and tolerability of vosaroxin plus cytarabine in patients with relapsed or refractory acute myeloid leukemia. Escalating vosaroxin doses (10-minute infusion; 10-90 mg/m2 on days 1, 4) were given in combination with cytarabine on 1 of 2 schedules: schedule A (24-hour continuous intravenous infusion, 400 mg/m2 per day on days 1-5) or schedule B (2-hour intravenous infusion, 1 g/m2 per day on days 1-5). Following dose escalation, enrollment was expanded at the maximum tolerated dose. The maximum tolerated dose for schedule A was vosaroxin 80 mg/m2 (dose-limiting toxicities: grade 3 bowel obstruction and stomatitis); the maximum tolerated dose was not reached for schedule B (recommended phase 2 dose: 90 mg/m2).

The median age in the study was 60 years, and patients had received as many as 6 prior cycles of therapy. Furthermore, most patients (89%) had intermediate or unfavorable cytogenetic risk status. The most common treatment-emergent nonhematologic adverse events of any grade were diarrhea, hypokalemia, nausea, and stomatitis. In the efficacy population, (all first relapsed or primary refractory patients treated with vosaroxin 80-90 mg/m2; n=69), the complete remission (CR) and combined CR rates (CR or CR with incomplete blood count recovery) were 25% and 28%, respectively. Thirty-day all-cause mortality was 2.5% among all patients treated at 80-90 mg/m2. Based upon these results, the phase 3 VALOR trial of vosaroxin plus cytarabine was initiated in patients with first relapsed or refractory acute myeloid leukemia.

"The results published in Haematologica online were the foundation for the VALOR trial, among the largest studies ever conducted in the relapsed or refractory AML setting," said Adam Craig, Chief Medical Officer of Sunesis. "Based on the outcome of VALOR, we plan to submit a Marketing Authorization Application for vosaroxin and look forward to discussing the data with the U.S. Food and Drug Administration. We also look forward to building upon these and other data for vosaroxin in AML through investigator-sponsored studies."

Angiogenesis is correlated with disease progression and poor prognosis in many tumor types, such as colon, lung, breast and gastric cancers. VEGF and KDR (VEGFR2) are over-expressed in most malignant tumors, such as gastric, liver, NSCLC, ovarian, brain, colorectal, and breast cancers and their signaling is key regulator for tumor angiogenesis. Researchers from PharmAbcine have developed Tanibirumab, an anti-VEGFR2/KDR fully human monoclonal antibody to treat solid tumors. Tanibirumab binds KDR and blocks binding of VEGFR ligands, including VEGF-A, VEGF-C and VEGF-D. Consequently, Tanibirumab inhibits ligand-stimulated activation of KDR, therefore inhibits ligand-induced angiogenesis, proliferation, and migration of human endothelial cells.

Tanibirumab had demonstrated anti-angiogenic efficacy against several cancer types and shown cross-species cross reactivity in multiple preclinical animal models including breast cancer, glioblastoma (GBM), lung cancer, colon cancer, and hepatocellular carcinoma (HCC). In November 2011, an open-label, non-randomized, dose-escalating phase I trial began to assess the safety and pharmacokinetics of Tanibirumab, administered intravenously, in 26 patients in Korea with advanced or metastatic cancer. The trial was finished in November 2013, with good safety and efficacy results. A phase II study of Tanibirumab in GBM is being planned.

"We are pleased to collaborate with PharmAbcine and look forward to moving Tanibirumab into clinical trials in China," Dr. Jing Lou, President and CEO of 3SBio commented, "3SBio continues to seek opportunities to expand our biologics pipeline, especially novel mAb candidates for refractory or metastatic cancers and other unmet medical needs, particularly in 3SBio’s core therapeutic areas of oncology and nephrology."

"Tanibirumab is a drug candidate with great potential to treat malignant tumors," Dr. Jin-San Yoo, President and CEO of PharmAbcine commented, "3SBio is a well-established industry leader with long-term vision in the innovative biological field in China, which makes them an ideal partner for strategic collaborations. We are looking forward to working with 3SBio to maximize this opportunity and benefit tens of thousands of Chinese patients suffering for cancers and other severe diseases."

Each year, over 1 million patients are diagnosed with various types of cancer in China1.
