New two-year follow-up of Roche's Columvi extends overall survival in relapsed or refractory diffuse large B-cell lymphoma patients

Core Insights - Roche announced two-year follow-up data from the phase III STARGLO study, showing a 40% improvement in overall survival for patients treated with Columvi® (glofitamab) in combination with gemcitabine and oxaliplatin (GemOx) compared to MabThera®/Rituxan® (rituximab) plus GemOx [1][4] Group 1: Study Results - The median follow-up was 24.7 months, with overall survival not reached for the Columvi combination, while it was 13.5 months for the R-GemOx group [1] - The Columvi combination demonstrated a 59% reduction in the risk of disease progression or death (hazard ratio = 0.41, 95% confidence interval: 0.29–0.58) [2] - Among patients achieving complete remission (CR) at the end of treatment, 89% were alive and 82% maintained remission one year post-treatment [2][4] Group 2: Treatment Implications - Columvi is approved in over 30 countries for patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) who are not candidates for autologous stem cell transplant [3] - The combination of Columvi and GemOx has been added to the National Comprehensive Cancer Network Clinical Practice Guidelines as a category 1 preferred recommendation for second-line DLBCL treatment [3] - There is an urgent need for rapidly available treatments for DLBCL, as many patients do not have access to the latest therapies [2][9] Group 3: Safety and Efficacy - The safety profile of the Columvi combination remained consistent with previous analyses, with a higher rate of adverse events observed, including cytokine release syndrome, which was generally low grade [2][4] - Patients receiving the Columvi combination had a higher median number of treatment cycles (11 versus 4) due to disease progression in the R-GemOx arm [2] Group 4: Company Strategy - Roche is focused on developing tailored treatment options for blood cancers, including the CD20xCD3 bispecific antibody program, which includes Columvi and Lunsumio® [5][7] - The company is also investigating Columvi in combination with other therapies for previously untreated DLBCL in ongoing studies [8]
