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).

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).

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).

Michael S. Hofman, MBBS, of the Peter MacCallum Cancer Centre, discusses phase II results from the ANZUP 1603 trial, which showed that in men with docetaxel-treated metastatic castration-resistant prostate cancer, LuPSMA was more active than cabazitaxel, with relatively fewer grade 3 and 4 adverse events and a more favorable PSA progression-free-survival (Abstract 5500).

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).

As Thomas Powles, MD, PhD, of Queen Mary University of London, prepares to deliver his late-breaking presentation at the ASCO20 Virtual Scientific Program (LBA-1), he talks with Christopher Sweeney, MBBS, of Dana-Farber Cancer Institute, about current therapy: PD1/PDL1 inhibition in second-line treatment and as monotherapy in the first-line setting, as well as the concept of maintenance switch.
