Clifford A. Hudis, MD, ASCO Chief Executive Officer, talks about extending the reach and impact of ASCO by partnering with patients who play a key role in advancing science through clinical trial participation. With near-record numbers of registered attendees, the 2023 Annual Meeting fostered new connections and plans for collaborations.
Catherine C. Coombs, MD, of the University of California, Irvine, discusses prolonged pirtobrutinib therapy, which continues to demonstrate a safety profile amenable to long-term administration at the recommended dose without evidence of new or worsening toxicity signals. The safety and tolerability observed in patients on therapy for 12 months or more were similar to previously published safety analyses of all patients enrolled, regardless of follow-up (Abstract 7513).
Shailender Bhatia, MD, of the University of Washington and Fred Hutchinson Cancer Center, discusses phase I/II results on the efficacy of nivolumab with or without ipilimumab in patients with recurrent or metastatic Merkel cell carcinoma. The study found that, for this rare and aggressive skin cancer, nivolumab showed clinical activity in advanced disease. However, these results from CheckMate 358 do not suggest an additional benefit with ipilimumab added to nivolumab (Abstract 9506).
Rana R. McKay, MD, of the University of California, San Diego, and Toni K. Choueiri, MD, of Dana-Farber Cancer Institute and Harvard Medical School, discuss results from the phase III CONTACT-03 study, showing that, for patients with metastatic renal cell carcinoma (RCC), adding the PD-L1 inhibitor atezolizumab to cabozantinib did not improve clinical outcomes compared with treatment with cabozantinib alone. In addition, higher toxicities were observed in the combination arm (Abstract LBA4500).
Smitha Krishnamurthi, MD, of the Cleveland Clinic, and Deb Schrag, MD, MPH, of Memorial Sloan Kettering Cancer Center, discuss phase III findings from the PROSPECT trial, which showed FOLFOX chemotherapy with selective use of radiation therapy and sensitizing fluoropyrimidine (5FUCRT) is noninferior to 5FUCRT for the neoadjuvant treatment of patients with locally advanced rectal cancer, prior to low anterior resection with total mesorectal excision (Abstract LBA2).
Nirav N. Shah, MD, of the Medical College of Wisconsin, discusses the efficacy and safety of pirtobrutinib, a highly selective, noncovalent BTK inhibitor, studied for more than 3 years in the BRUIN trial. The results showed that the use of pirtobrutinib continues to have durable efficacy and a favorable safety profile in heavily pretreated patients with relapsed or refractory mantle cell lymphoma and prior BTK inhibitor therapy. Responses were observed in patients with high-risk disease features, including blastoid/pleomorphic variants, elevated Ki67 index, and TP53 mutations (Abstract 7514).
