RB1 positive prostate cancer no benefit Palbociclib Phase II Actionable In a Phase II trial, addition of Ibrance (palbociclib) to androgen deprivation therapy (ADT) did not improve the rate of PSA less or equal to 4 ng/ml at 28 weeks (80%, 32/40 vs 80%, 16/20, p=0.87), PSA undetectable rate at 28 weeks (43% vs 50%, p=0.5), radiographic response rate (89% vs 89%), or 12-month biochemical progression-free survival (74% vs 69%, p=0.72) in patients with metastatic hormone-sensitive prostate cancer expressing Rb1 as confirmed by IHC (PMID: 33727260; NCT02059213). 33727260
