Benoit You, MD, PhD, on Endometrial Cancer: New Data on Combining Olaparib, Cyclophosphamide, and Metformin
AACR Annual Meeting 2022
Benoit You, MD, PhD, of the Lyon University Hospital (France), discusses phase I/II safety and efficacy results from the ENDOLA trial that combined olaparib with metronomic cyclophosphamide and metformin in patients with advanced pretreated endometrial cancer. At 10 weeks, the non–disease progression rate was 61.5%, reaching the primary endpoint of the study. Median progression-free survival was 5.1 months. Research on biomarkers of efficacy is ongoing (Abstract CT005).

Timothy A. Yap, MBBS, PhD, of The University of Texas MD Anderson Cancer Center, discusses results from the PETRA study, a first-in-class, first-in-human trial of the next-generation PARP1-selective inhibitor AZD5305 in patients with BRCA1/2, PALB2, or RAD51C/D mutations in advanced or metastatic ovarian cancer, HER2-negative breast cancer, pancreatic, or prostate cancer. Target engagement was demonstrated across all dose levels, and antitumor activity was observed in selected tumor and molecular subtypes.

Timothy A. Yap, MBBS, PhD, of The University of Texas MD Anderson Cancer Center, discusses how research is building on the success of first-generation PARP inhibitors in the clinic and the potential of novel potent PARP1-selective inhibitors, which may lead to improved patient outcomes. Given recent advances in drug discovery, says Dr. Yap, we now can go beyond PARP by drugging other key DNA damage response targets in the clinic, including ATR, WEE1, DNA-PK, RAD51, POLQ, and USP1.

Nicolas Girard, MD, PhD, of the Institut Curie, discusses findings from the phase III CheckMate 816 trial, which is the first study with an immunotherapy-based combination to demonstrate improved event-free survival and pathologic complete response in the neoadjuvant setting for patients with resectable stage IB to IIIA non–small cell lung cancer. The results may benefit the 30% to 55% of patients whose cancer recurs after surgery (Abstract CT012).

Klaus Pantel, MD, of the University Medical Center Hamburg-Eppendorf, discusses liquid biopsy technologies and biomarkers, with a focus on circulating tumor cells and circulating tumor DNA; clinical applications such as early detection of cancer, improved staging, and surveillance of measurable residual disease; and how best to detect and monitor response to systemic therapies, as well as ways to identify therapeutic targets and resistance mechanisms (Abstract SY08).

Timothy A. Yap, MBBS, PhD, of The University of Texas MD Anderson Cancer Center, discusses results from a phase Ib expansion trial of the safety and efficacy of the oral ataxia telangiectasia and Rad3-related (ATR) inhibitor elimusertib in advanced solid tumors with DNA damage response defects. Elimusertib is a selective inhibitor of ATR, a key regulator of responses to DNA damage and replication stress, with antitumor activity in preclinical models of various solid tumors and lymphoma (Abstract CT006).
