Popis: This randomized, phase II study assessed the activity of oblimersen sodium, a Bcl-2 antisense oligonucleotide, administered before docetaxel (Taxotere) to patients with castration-resistant prostate cancer.Chemotherapy-naive patients with prostate-specific antigen (PSA) progression and testosteroneor = 0.5 ng/ml received docetaxel 75 mg/m2 on day 1 or oblimersen 7 mg/kg/day continuous i.v. infusion on days 1-7 with docetaxel 75 mg/m2 on day 5 every 3 weeks foror = 12 cycles. Primary end points were confirmed PSA response (Bubley criteria) and major toxic events.Confirmed PSA response was observed in 46% and 37% of 57 and 54 patients treated with docetaxel and docetaxel-oblimersen, respectively. Partial response (RECIST) was achieved in 18% and 24%, respectively. Oblimersen added to docetaxel was associated with an increase in the incidence of gradeor = 3 fatigue, mucositis, and thrombocytopenia. Major toxic events were reported in 22.8% and 40.7% of patients with docetaxel and docetaxel-oblimersen, respectively.The primary end points of the study were not met: a rate of confirmed PSA response30% and a major toxic event rate45% were not observed with docetaxel-oblimersen.
