GTx: Enobosarm POWER Trials Fail To Meet Overall Criteria - Quick Facts

GTx Inc. (GTXI) announced results of its two Phase 3 enobosarm clinical trials, the POWER trials, in patients with non-small cell lung cancer or NSCLC receiving chemotherapy. The company announced that the clinical trials failed to meet the overall criteria for the co-primary responder endpoints of lean body mass and physical function as agreed upon with the United States Food and Drug Administration or FDA.

The responder endpoints showed mixed results (for POWER1 and POWER2, p values at Day 84 for LBM were 0.036 and 0.113, respectively; p values at Day 84 for SCP were 0.315 and 0.289, respectively).

According to the company, Initial exploratory quantitative (continuous variable) analysis demonstrated that enobosarm had a consistent effect on LBM relative to placebo in both studies at all assessment times (p values were 0.0003 and 0.0227 at Day 84 for POWER1 and POWER2, respectively). Corresponding analyses for SCP were inconsistent between trials (p values were 0.0336 and 0.7923, respectively). Missing data were well balanced between the arms in both trials for both endpoints.

Across both clinical trials, enobosarm was generally well tolerated, with the occurrence of serious adverse events and overall incidence of adverse events similar across placebo and treatment groups, the company said.

In POWER1, the four most common adverse events reported (in decreasing order of incidence) were nausea, alopecia, anemia and vomiting.

In POWER2, the four most common adverse events reported were anemia, nausea, neutropenia and vomiting. In the safety analysis of survival, there was no evidence of a difference between patients treated with enobosarm and placebo in either clinical trial.

"While we are disappointed that both studies did not meet the pre-specified responder analyses, we are encouraged by the unambiguous effect of enobosarm on muscle and we are confident that it will translate to clinical benefit and potentially increase survival in patients with non-small cell lung cancer," said Mitchell Steiner, M.D., CEO of GTx.

The company noted that it plans to initiate discussions with both the FDA and European regulatory authorities to determine the path forward.
