Timothy A. Yap, MBBS, PhD, on Advanced Solid Tumors With DNA Damage Response Defects: Early Data on Elimusertib
AACR Annual Meeting 2022
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).

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.

Lillian L. Siu, MD, of Canada’s Princess Margaret Cancer Centre, discusses biomarker-driven precision cancer medicine, the optimal sequencing of immunotherapy (IO) with standard treatments in curative settings, IO targets beyond PD-1/PD-L1 and combinatorial strategies, and next-generation adoptive cell therapies (Abstract PL06).

Gautam Mehta, MD, of the U.S. Food and Drug Administration, discusses how accelerated approval of potentially life-saving cancer therapies has been applied in precision oncology. Although “fast-tracking” drugs presents opportunities and challenges, one possible measure of the program’s success is the fact that, to date, no solid tumor accelerated-approval indications have been withdrawn (Abstract DC06).

Jia Luo, MD, of Dana-Farber Cancer Institute, discusses the emerging class of cancer therapies for allele-specific KRAS inhibitors and the importance of their distinct clinical, genomic, and immunologic features. Because KRAS G12D–mutated non–small cell lung cancer is associated with worse responses to immunotherapy, Dr. Luo believes drug development will need to take these differences into account (Abstract 4117).

Meenakshi Anurag, PhD, of Baylor College of Medicine, discusses results from the ALTERNATE trial, which showed the combination of anastrozole plus fulvestrant was superior to either drug alone in inhibiting tumor proliferation in postmenopausal women with early-stage luminal B breast cancer (Abstract CT026).
