OncoGenex Phase 2 Borealis-1 trial resulted in 50% reduction in risk of death OncoGenex Pharmaceuticals announced results from the randomized, controlled Phase 2 Borealis-1 trial evaluating low and high dose apatorsen in combination with gemcitabine/cisplatin chemotherapy compared to chemotherapy alone in the treatment of metastatic bladder cancer. Overall trial results indicated that the addition of 600mg apatorsen to standard of care chemotherapy showed a 14% reduction in risk of death and a 17% reduction in progressive disease and death when compared to chemotherapy alone. Over one-third of the patients in the trial had lower performance status, as defined by a Karnofsky score of 80 percent or less. These patients derived the greatest benefit from 600mg apatorsen in combination with chemotherapy, resulting in a 50% reduction in risk of death compared to chemotherapy alone. Less benefit was observed in the 1000mg apatorsen arm due to increased adverse events leading to a higher rate of discontinuation of both apatorsen and chemotherapy. Apatorsen 600mg was well tolerated in combination with chemotherapy.
