Janssen Presents Results from Phase 3 ACIS Study in Patients with Metastatic Castration-Resistant Prostate Cancer Treated with ERLEADA ® (apalutamide) and ZYTIGA® (abiraterone acetate) Combination

RARITAN, N.J., February 8, 2021 – The Janssen Pharmaceutical Companies of Johnson & Johnson announced today results from the randomized, double-blind, placebo-controlled Phase 3 ACIS study, which met the primary endpoint of radiographic progression-free survival (rPFS) with a 31 percent reduction in the risk of radiographic progression or death in patients with chemotherapy-naïve metastatic castration-resistant prostate cancer (mCRPC) receiving androgen deprivation therapy (ADT). Patients in the trial received either a combination of ERLEADA® and ZYTIGA® plus prednisone (combination arm) or placebo and ZYTIGA® plus prednisone (control arm).[i] Results will be featured in an oral presentation at the American Society of Clinical Oncology’s Genitourinary (ASCO GU) Cancers Symposium, taking place virtually February 11-13, 2021 (Abstract #9; Oral Abstract Session: Prostate Cancer, February 11, 12:45 PM-2:00 PM EST).The primary efficacy analysis showed median rPFS was extended by six months in patients treated in the combination arm compared with patients in the control arm (22.6 vs. 16.6 months; hazard ratio [HR] 0.69 [95% CI, 0.58-0.83]; p<0.0001). The HR for radiographic progression or death as assessed by blinded independent central review (BICR) was 0.864 [95% CI, 0.718–1.040]. According to an updated analysis performed at a median follow-up of 54.8 months, a 30 percent reduction in the risk of radiographic progression or death was shown in the combination arm...
