Olaparib-Temozolomide Combination Fails to Improve Outcomes in Advanced Uterine Leiomyosarcoma
- The phase 2/3 Alliance A092104 trial evaluating olaparib plus temozolomide in advanced uterine leiomyosarcoma failed to meet its primary progression-free survival endpoint compared to standard care.
- The combination showed a median PFS of 3.2 months versus 5.5 months with investigator's choice of pazopanib or trabectedin, leading to early trial closure for futility.
- Despite promising early-phase data, the study highlights the challenge of demonstrating superiority over existing therapies in this rare cancer population.
- The trial will be closed on October 1, 2025, with researchers emphasizing the need to better identify which patients might benefit from molecularly targeted approaches.
