“Disappointing update from ESMO 23: Christina Gratzke reveals KEYNOTE-991 study results, emphasising the complexities of treating metastatic hormone-sensitive prostate cancer (mHSPC). Here’s what we’ve learned:

KEYNOTE-991 Study Insights:
– Study halted: Pembro + Enza + ADT didn’t improve outcomes in mHSPC patients, escalating risks instead.
– rPFS, OS, and TT SSE outcomes were comparable between Pembro + Enza vs PBO + Enza groups.
– Significant increase in Grade ≥3 Treatment-Related Adverse Events (TRAEs) observed with the combination therapy .

This setback highlights the challenges in prostate cancer research and underscores the importance of rigorous evaluation in clinical trials. Research continues for better solutions in the fight against mHSPC.”
