Ann H. Partridge, MD, MPH, and Véronique Diéras, MD, on the Future of Cytotoxic Therapy: Antibody-Drug Conjugates?
2022 ASCO Annual Meeting
Ann H. Partridge, MD, MPH, of Dana-Farber Cancer Institute, and Véronique Diéras, MD, of the Centre Eugène Marquis, discuss the many challenges posed by next-generation antibody-drug conjugates (ADCs). They include side effects such as hematotoxicity, gastrointestinal toxicities, and interstitial lung disease; tumor targeting and payload release; drug resistance; and the urgent need to understand ADCs’ mechanisms of action to better sequence and combine drugs.

Ursula A. Matulonis, MD, of Dana-Farber Cancer Institute, and Nicoletta Colombo, MD, of the University of Milan and the European Institute of Oncology, discuss phase II results on the overall survival benefit of intermittent relacorilant, a selective glucocorticoid receptor modulator, combined with nab-paclitaxel, compared with nab-paclitaxel alone in patients with recurrent platinum-resistant ovarian cancer. A phase III trial comparing intermittent relacorilant plus nab-paclitaxel with investigator’s choice of chemotherapy in primary platinum-refractory disease is ongoing (Abstract LBA5503).

Courtney D. DiNardo, MD, MSCE, of The University of Texas MD Anderson Cancer Center, and Stéphane de Botton, MD, PhD, of Institut Gustave Roussy, discuss phase III findings from the IDHENTIFY trial, which showed that mutational burden and co-mutational profiles differed between patients with relapsed or refractory acute myeloid leukemia that exhibited IDH2-R140 and IDH2-R172 mutations. Enasidenib improved survival outcomes for patients with IDH2-R172 mutations: median overall survival and 1-year survival rates were approximately double those in the conventional care arm (Abstract 7005).

Gilberto de Lima Lopes, Jr, MD, MBA, of the Sylvester Comprehensive Cancer Center at the University of Miami, and Karen L. Reckamp, MD, of Cedars-Sinai Medical Center, discuss phase II findings from substudy S1800A of the Lung-MAP protocol. The data showed that ramucirumab and pembrolizumab improved overall survival compared with the standard of care for patients with advanced non–small cell lung cancer who were previously treated with immunotherapy and platinum-based chemotherapy (Abstract 9004).

Benoit You, MD, PhD, of Lyon University hospital (HCL, France) and GINECO group (France), discusses findings from the GOG-0218 trial of patients with ovarian cancer, which appears to confirm earlier data on the link between poor tumor chemosensitivity and benefit from concurrent plus maintenance bevacizumab. In Dr. You’s validation study, patients who derived the most progression-free and overall survival benefit from bevacizumab were those with high-risk disease (stage IV or incompletely resected stage III) associated with an unfavorable KELIM score (CA-125 kinetic elimination rate constant, calculable online) (Abstract 5553).

Nabil F. Saba, MD, of Winship Cancer Institute of Emory University, discusses new data from a trial of pembrolizumab and cabozantinib in patients with recurrent metastatic head and neck squamous cell carcinoma. The study met its primary endpoint of overall response rate. The regimen was well tolerated and exhibited encouraging clinical activity in this patient population (Abstract 6008).
