Timothy A. Yap, MBBS, PhD, on Ovarian, Breast, Pancreatic, and Prostate Cancers With Genetic Mutations: A First-in-Human Trial of AZD5305
AACR Annual Meeting 2022
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.

Ari M. VanderWalde, MD, MPH, MBioeth, of The West Clinic, discusses results from the S1616 trial involving patients with metastatic or unresectable melanoma who had primary resistance to PD-1 or PD-L1 inhibitors. Compared with ipilimumab alone, the combination of ipilimumab plus nivolumab benefited some patients: those with tumors that responded to therapy showed an increased amount of CD8+ cells. Because there is no standard treatment for metastatic melanoma after failure of PD-1 inhibitors in BRAF wild-type disease, this research may provide a viable option in the future (Abstract CT013).

Cheryl L. Willman, MD, of the Mayo Clinic Comprehensive Cancer Center, discusses the profound cancer health disparities among Native Americans, exacerbated by low rates of screening and limited access to care. Dr. Willman is heading an effort to promote community engagement in comprehensive genomic sequencing with the hope that researchers will discover novel mutations and genome-wide mutational signatures that can ultimately be translated to improved screening and therapy in this population (Abstract PL03).

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).

Gulam A. Manji, MD, PhD, of Columbia University Medical Center, discusses phase II results on perioperative combination chemotherapy and pembrolizumab in patients with resectable gastric cancer. The combination appeared to result in many complete pathologic responses (Abstract CT009).

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.
