Douglas B. Johnson, MD, on Melanoma: Clinical Trials Update on PD-1 and CTLA-4 Blockade
ASCO20 Virtual Scientific Program
Douglas B. Johnson, MD, of Vanderbilt University Medical Center, discusses three important melanoma abstracts: the need for more than two doses of nivolumab plus ipilimumab in combination immunotherapy; antitumor activity for low-dose ipilimumab with pembrolizumab after disease progression on PD-1 antibodies; and ipilimumab alone or in combination with anti–PD-1 therapy for metastatic disease resistant to PD-1 monotherapy (Abstracts 10003, 10004, and 10005).

David R. Wise, MD, PhD, of New York University Perlmutter Cancer Center, summarizes three important studies in prostate cancer: circulating tumor cell count as a prognostic marker of PSA response and progression in metastatic castration-sensitive disease; new phenotypic subtypes; and how circulating tumor DNA dynamics associate with treatment response and radiologic progression-free survival (Abstracts 5506, 5507, and 5508).

Lakshmi Nayak, MD, of Dana-Farber Cancer Institute, reviews two key abstracts on newly diagnosed primary central nervous system lymphoma and treatment with whole-brain radiotherapy, methotrexate, temozolomide, rituximab, procarbazine, vincristine, and cytarabine (Abstracts 2500 and 2501).

Seema A. Khan, MD, MPH, of the Lynn Sage Comprehensive Breast Center, discusses phase III trial results showing that in newly diagnosed metastatic stage IV breast cancer, locoregional treatment of the primary tumor did not offer a greater survival benefit than systemic therapy (Abstract LBA2).

Nikhil C. Munshi, MD, of Dana-Farber Cancer Institute, discusses initial results from the KarMMa tria, showing that idecabtagene vicleucel, a B-cell maturation antigen-targeted CAR T-cell therapy, demonstrated deep and durable responses in patients with heavily pretreated relapsed or refractory multiple myeloma. Efficacy and safety data support a favorable clinical benefit-risk profile across the target dose range (Abstract 8503).

Cynthia X. Ma, MD, PhD, of Washington University, discusses results from the ALTERNATE trial, which showed neither fulvestrant nor fulvestrant plus anastrozole significantly improved endocrine-sensitive disease rate compared with anastrozole alone in postmenopausal patients with locally advanced estrogen receptor–positive, HER2-negative breast cancer (Abstract 504).
