Study Summaries

SOLO-3: Olaparib vs. Chemotherapy in PSROC

Olaparib significantly improved PFS and ORR over nonplatinum chemotherapy, though no OS benefit was observed in the overall population. In patients with ≥3 prior therapies, chemotherapy had more favorable OS.

NRG-GY023: Comparing Durvalumab, Olaparib, and Cediranib Monotherapy, Combination Therapy, or Chemotherapy in Patients with Platinum-Resistant Ovarian Cancer with Prior Bevacizumab

The addition of durvalumab with olaparib and cediranib did not improve PFS in platinum-resistant ovarian cancer patients with prior bevacizumab exposure.

ARIEL 4

PALETTE STUDY - Pazopanib for sarcoma

PALEO Trial: Palbociclib + Letrozole in Endometrial Cancer

The combination of palbociclib and letrozole significantly improved PFS compared to placebo with letrozole. However, it was associated with higher hematologic toxicities, particularly neutropenia.

Fulvestrant + Abemaciclib

The combination of abemaciclib and fulvestrant shows promising efficacy and manageable toxicity in HR-positive advanced or recurrent endometrial cancer, especially in CN-L/NSMP tumors

LEAP-001: Pembro/Lenvima vs. Carbo/Taxol in Advanced/Recurrent Endometrial Cancer

First-line lenvatinib plus pembrolizumab did not significantly improve PFS or OS compared to chemotherapy in mismatch repair-proficient (pMMR) advanced endometrial cancer. Toxicity was higher in the experimental arm but manageable. dMMR exploratory analysis shows promise in this subgroup.

CHIPOR Trial: Secondary Debulking and HIPEC in Platinum Sensitive Recurrence

HIPEC combined with cytoreductive surgery significantly improved overall survival and progression-free survival in recurrent ovarian cancer

PAOLA-1: Olaparib plus Bevacizumab as First-Line Maintenance in Ovarian Cancer (Overall Survival)

Olaparib combined with bevacizumab provided a OS benefit for HRD-positive ovarian cancer patients.

Keynote B-21: Pembrolizumab vs. Placebo in High-risk Endometrial Cancer

Adjuvant Pembrolizumab did not improve DFS in high-risk endometrial cancer population
