CAMBRIDGE, Mass.--(BUSINESS WIRE)-- BIND Therapeutics, Inc. (NASDAQ: BIND), a clinical-stage nanomedicine company developing targeted and programmable therapeutics called ACCURINS®, today announced the presentation of complete data from its phase 2 clinical trial of BIND-014, a PSMA-targeted ACCURIN containing docetaxel, in patients with chemotherapy-naive metastatic castration-resistant prostate cancer (mCRPC) who either were or were not exposed to anti-androgens (abiraterone acetate and/or enzalutamide). BIND-014 was clinically active and well-tolerated and the study met its primary endpoint with 71 percent of patients achieving rPFS of at least 6 months. The complete data are being presented on January 7, 2016 during a poster session at the 2016 Genitourinary Cancers Symposium held in San Francisco.
"We are encouraged by the safety and activity profile of BIND-014 in this phase 2 trial, which support its potential to be a nanomedicine alternative superior to conventional docetaxel," said Hagop Youssoufian, M.D., M.Sc., chief medical officer, BIND Therapeutics. "Although these data are encouraging, recent advances with anti-androgen therapy limit our ability to compare BIND-014 data to historical benchmarks. At this time, we are not planning further development of BIND-014 in mCRPC given the evolving treatment landscape. We anticipate additional BIND-014 data from both the iNSITE 1 trial in squamous histology non-small cell lung cancer and the iNSITE 2 trial in multiple tumor types during the first quarter of 2016, which we expect to determine our next steps in the clinical development of BIND-014."
In addition to the primary endpoint, data presented from the trial included measurements of safety and tolerability, objective response rates (ORR), prostate-specific antigen (PSA) response, changes in circulating tumor cells (CTC) and overall survival (OS). Key results include:
BIND-014 administered at 60 mg/m² on day 1 of a 21-day cycle was clinically active and well-tolerated when administered to patients (n=42) with chemotherapy-naive mCRPC, including the 74% of patients with prior exposure to abiraterone acetate and/or enzalutamide.
Median rPFS of 9.9 months (95% CI, 7.1 - 12.6) was achieved (n=42 with 8 censored).
A confirmed ORR of 21% was observed in patients with measurable disease (n=19).
A 50% reduction in PSA was observed in 30% of PSA evaluable patients (n=40).
CTC conversion from ≥ 5 cells/7.5 mL blood at baseline to < 5 cells/7.5 mL blood was observed in 50% of patients.
Median OS was 13.4 months (95% CI, 9.9 - 18.6 months [n=42 with 10 censored]).
About BIND Therapeutics
BIND Therapeutics is a clinical-stage nanomedicine company developing a pipeline of ACCURINS®, its novel targeted therapeutics designed to increase the concentration and duration of therapeutic payloads at disease sites while reducing exposure to healthy tissue. BIND is leveraging its Medicinal Nanoengineering® platform to develop a pipeline of ACCURINS targeting hematological and solid tumors and has a number of strategic collaborations with biopharmaceutical companies to develop ACCURINS in areas of high unmet need. BIND's lead drug candidate, BIND-014, is a prostate-specific membrane antigen (PSMA) -targeted ACCURIN that contains docetaxel, a clinically-validated and widely-used cancer chemotherapy drug. BIND is currently enrolling patients in a trial with BIND-014 for non-small cell lung cancer, or NSCLC, with squamous histology. In addition, BIND is enrolling patients in a clinical trial with BIND-014 for advanced cancers of the cervix, bladder, head and neck or biliary tree (cholangiocarcinoma). BIND is advancing BIND-510, its second PSMA-targeted ACCURIN drug candidate containing vincristine, a potent microtubule inhibitor with dose limiting peripheral neuropathy in its conventional form, through important preclinical studies to potentially position it for an Investigational New Drug (IND) application filing with the U.S. Food and Drug Administration. BIND is also developing ACCURINS designed to inhibit PLK1 and KSP, both of which BIND believes are promising anti-mitotic targets that have been limited in the clinic due to systemic toxicity at or below their therapeutic doses.
BIND has announced ongoing collaborations with Pfizer Inc., AstraZeneca AB, F. Hoffmann-La Roche Ltd., Merck & Co., or Merck (known as Merck Sharp & Dohme outside the United States and Canada) and Macrophage Therapeutics (a subsidiary of Navidea Biopharmaceuticals) to develop ACCURINS based on their proprietary therapeutic payloads and/or targeting ligands. BIND's collaboration with AstraZeneca has resulted in the Aurora B Kinase inhibitor ACCURIN AZD2811, which became the second ACCURIN candidate to enter clinical development. BIND's collaboration with Pfizer has resulted in the selection of an ACCURIN candidate that is entering IND-enabling studies.
