Paul G. Richardson, MD, of Dana-Farber Cancer Institute, discusses early results on a cereblon E3 ligase modulator agent combined with dexamethasone in patients with relapsed or refractory multiple myeloma, with an overall response rate of 48%. The study is ongoing to further optimize dose and schedule (Abstract 8500).
Sara A. Hurvitz, MD, of UCLA’s David Geffen School of Medicine, summarizes four breast cancer studies: KATHERINE, on adjuvant trastuzumab vs trastuzumab in patients with residual invasive disease after neoadjuvant therapy for HER2-positive breast cancer; KAITLIN, on trastuzumab emtansine and pertuzumab vs trastuzumab, pertuzumab, and taxane after anthracyclines as adjuvant therapy for high-risk HER2-positive early breast cancer; TRAIN-2, on neoadjuvant chemotherapy with or without anthracyclines for HER2-positive disease; and PHERGain, on chemotherapy de-escalation using an FDG-PET/CT and pathologic response–adapted strategy in HER2-positive early breast cancer (Abstracts 500, 501, 502, and 503).
Mikkael A. Sekeres, MD, of the Cleveland Clinic, discusses data from a phase II study of pevonedistat plus azacitidine vs azacitidine alone in patients with higher-risk myelodysplastic syndromes, chronic myelomonocytic leukemia, or low-blast acute myeloid leukemia (Abstract 7506).
Rachel E. Sanborn, MD, of the Providence Cancer Institute, discusses three key abstracts on EGFR-mutated non–small cell lung cancer: a final overall survival analysis of bevacizumab plus erlotinib; concurrent osimertinib plus gefitinib for first-line treatment; and first-line treatment with a tyrosine kinase inhibitor with or without aggressive upfront local radiation therapy (Abstracts 9506, 9507, 9508).
Roy S. Herbst, MD, PhD, of Yale Cancer Center, discusses data from the ADAURA study, which showed that compared with placebo, osimertinib as adjuvant therapy after complete tumor resection reduced the risk of disease recurrence or death by 79% in patients with non–small cell lung cancer (Abstract LBA5).
Nancy U. Lin, MD, of Dana-Farber Cancer Institute, discusses the HER2CLIMB study of patients with previously treated HER2-positive metastatic breast cancer that had metastasized to the brain. Adding tucatinib to trastuzumab and capecitabine doubled the intracranial response rate and reduced the risk of death by nearly half, compared with trastuzumab plus capecitabine (Abstract 1005).
