Priscilla K. Brastianos, MD, on CNS Metastases: Understanding Their Evolution and the Clinical Implications
AACR Annual Meeting 2022
Priscilla K. Brastianos, MD, of Harvard Medical School and Massachusetts General Hospital, talks about her efforts to better understand how brain metastases evolve genomically and to test such agents as abemaciclib, paxalisib, and entrectinib, which may stop their growth. Palbociclib, a CDK inhibitor, has already shown potential benefit. A national cooperative group trial is underway in multiple centers to identify novel treatments for patients with brain metastases, who typically have a poor prognosis (Abstract SY38).

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).

Iván Márquez-Rodas, MD, PhD, of Spain’s Hospital General Universitario Gregorio Marañón, discusses final results of the phase II SPOTLIGHT203 study of systemic pembrolizumab in combination with intratumoral BO-112 for patients with advanced melanoma refractory to anti–PD-1–based therapy. The regimen achieved an overall response rate of 25% and a disease control rate of 65% (Abstract CT014).

Zev Wainberg, MD, of the University of California, Los Angeles Medical Center, discusses preliminary data on the safety and efficacy of TTX-030, an anti-CD39 antibody, in combination with budigalimab and FOLFOX for the first-line treatment of locally advanced or metastatic gastric or gastroesophageal junction adenocarcinoma. The study suggests the regimen may prove to be of benefit as a first-line treatment, regardless of combined positive score status (Abstract CT015).

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).

Josh Neman, PhD, of the Keck School of Medicine, University of Southern California, discusses the distribution of brain metastasis to preferential brain regions that vary according to cancer subtype, how neurotransmitters respond, and the ways in which the central nervous system acclimates (Abstract SY32).
