"The launch of Borealis-2 marks OncoGenex' continued commitment to expanding the OGX-427 clinical development program to better understand treatment resistance in GU cancers," said Scott Cormack, President and Chief Executive Officer of OncoGenex. "Given the growing incidence of bladder cancer due to an aging population, we believe there is an urgent need to identify new strategies to address treatment resistance and potentially improve outcomes in this patient population."
Borealis-2 will be the second randomized, controlled clinical trial of OGX-427 in advanced bladder cancer. The Borealis-1 clinical trial is the OncoGenex-sponsored, randomized, placebo-controlled Phase 2 study designed to evaluate a potential survival benefit, safety and tolerability of combining OGX-427 with gemcitabine and cisplatin in the first-line treatment of patients with advanced bladder cancer. If either Borealis trial shows a survival advantage, OncoGenex plans to initiate conversations with the Food and Drug Administration about the possibility of a Phase 3 study of OGX-427 in bladder cancer as part of the ORCA program.
The Borealis-2 clinical trial will randomize approximately 200 patients to receive either OGX-427 plus docetaxel treatment or docetaxel treatment alone. Patients may also continue weekly OGX-427 infusions as maintenance treatment until disease progression or unacceptable toxicity if they complete all 10 planned cycles of docetaxel or are discontinued from docetaxel due to docetaxel toxicity. The primary objective will be overall survival, with secondary objectives evaluating safety, tolerability, tumor response rates and the effect of therapy on Hsp27 levels and circulating tumor cells.
Borealis-2 will be conducted at approximately 30 sites in the U.S. and is being sponsored by the Hoosier Oncology Group. Dr.
Simon Cancer Center, Dr.
from the Dana-Farber Cancer Institute and Dr.
from Memorial Sloan-Kettering Cancer Center will serve as the primary investigators on the study.
The "ORCA" (Overcoming Resistance in CAncer) program encompasses the on-going studies of OGX-427 aiming to demonstrate that inhibition of Hsp27 can lead to improved prognosis and treatment outcomes for cancer patients. Phase 2 clinical trials are underway in prostate and bladder cancers, with additional studies expected to initiate this year. For more information on OGX-427 and ORCA, please visit
