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).
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.
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measure of the program’s success is the fact that, to date, no solid tumor accelerated-approval indications have been withdrawn (Abstract DC06).
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).
Matthew L. Meyerson, MD, PhD, of the Dana-Farber Cancer Institute, discusses study findings that suggest the variation in frequency of EGFR and KRAS mutations in lung cancer may be associated with genetic ancestry in patients from Latin America. The results indicate it may be possible to identify germline alleles underpinning this link. Finding a germline locus or loci may impact the development of lung cancers with these mutations and may improve lung cancer prevention and screening for populations of Latin American origin, as well as others.
Tina Cascone, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses the findings of the phase II NeoCOAST study, which showed that combination immunotherapy with the anti–PD-L1 monoclonal antibody durvalumab and other novel agents resulted in numerically higher major pathologic response rates than durvalumab alone in the neoadjuvant setting for patients with early-stage resectable non–small cell lung cancer. Translational results also supported combination therapies over single-agent therapy (Abstract CT011).
