Management Comments

• We recently made the difficult decision to terminate the clinical development of masofaniten, and withdraw the related IND and CTAs, based on an interim analysis of the data from the Phase 2 combination study, concluding that masofaniten combined with enzalutamide was unlikely to meet its primary endpoint, said David Parkinson, MD, President and CEO of ESSA.
• We are currently evaluating and reviewing our strategic options focused on maximizing shareholder value and look forward to providing further updates in the near future.

Industry Context

The failure of the masofaniten trial highlights the challenges in developing new treatments for prostate cancer, a competitive space with many companies pursuing novel therapies. The decision to halt the trial and explore strategic options is a significant shift for ESSA, reflecting the high-risk nature of pharmaceutical development.

Comparison to Industry Standards

• The failure of the Phase 2 trial is a setback compared to other companies that have shown positive results in similar trials, such as Astellas and Pfizer with their drug Xtandi (enzalutamide) which is the control arm in this trial.
• The PSA90 response rate in the control arm was much higher than expected based on historical data, suggesting a potential shift in the standard of care or patient population characteristics.
