Core Insights - Roche's phase III SUNMO study demonstrated that the combination of Lunsumio® (mosunetuzumab) and Polivy® (polatuzumab vedotin) significantly improves progression-free survival (PFS) and objective response rate (ORR) in patients with relapsed or refractory large B-cell lymphoma (LBCL) compared to the standard treatment R-GemOx [1][2][3] Study Results - The combination therapy showed a 59% reduction in the risk of disease progression or death (hazard ratio [HR] 0.41, p<0.0001) with a median PFS of 11.5 months, three times longer than R-GemOx's 3.8 months [2][3] - The 12-month PFS rate was 48.5% for the combination therapy compared to 17.8% for R-GemOx [2] - Objective response rates were 70.3% for the combination versus 40.0% for R-GemOx, with complete response rates at 51.4% compared to 24.3% [2] Safety Profile - The safety profile of the combination was consistent with known profiles of the individual drugs, with low incidence of cytokine release syndrome (CRS) and fewer adverse events leading to treatment discontinuation [2][3] - Grade 3-4 adverse events were similar between the two treatment arms (58.5% vs. 57.8%) [2] Clinical Implications - The combination therapy may provide an effective alternative to traditional chemotherapy, suitable for outpatient settings, addressing the urgent need for new treatment options in difficult-to-treat LBCL [2][4] - The National Comprehensive Cancer Network (NCCN) has included Lunsumio and Polivy in its guidelines as a category 2A recommendation for second-line treatment of DLBCL [2] Roche's Commitment - Roche aims to enhance treatment options for patients with lymphomas through its extensive portfolio, including ongoing studies with other bispecific antibodies and combination therapies [5][11] - Lunsumio is already approved in over 60 countries for relapsed or refractory follicular lymphoma, while Polivy has approvals in over 100 countries for various indications [6][9]
