On January 19, 2023, the FDA accelerated the approval of tucatinib (Tukysa; Seagen), a Bruton tyrosine kinase inhibitor, in combination with trastuzumab (Herceptin), a HER2/neu receptor agonist, for the treatment of RAS wild-type, HER2-positive unresectable or metastatic colorectal cancer (CRC) that progressed after fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapies. This combination was granted a breakthrough therapy designation for this indication. Read More ›

Promising antitumor activity and a tolerable safety profile were found in patients with previously treated gastric or gastroesophageal cancer treated with trifluridine/tipiracil combined with ramucirumab. Read More ›
Insertion-deletion rate and high tumor mutation burden in advanced gastric cancer was found to be associated with favorable progression-free survival and overall survival in patients treated with nivolumab. Read More ›

Early results from the CheckMate-648 clinical trial, which evaluated the 1 and safety of Opdivo (nivolumab), a PD-1 inhibitor, plus Yervoy (ipilimumab), a CTLA-4 inhibitor, or nivolumab plus chemotherapy, sugge1st a potential new standard of care for the first-line treatment of patients with advanced esophageal squamous-cell carcinoma (ESCC). These findings were presented at the American Society of Clinical Oncology (ASCO) 2021 virtual annual meeting by Ian Chau, MD, Consultant Medical Oncologist, Gastrointestinal and Haemato-Oncology, Royal Marsden Hospital, Sutton, United Kingdom, and lead investigator of the trial.
