FDA accepts supplemental Biologics License Application for Roche’s Lunsumio and Polivy combination for people with relapsed or refractory large B-cell lymphoma

• Filing acceptance based on data from the phase III SUNMO study where subcutaneous Lunsumio VELO plus Polivy demonstrated a 59% reduction in risk of disease progression or death¹
• People with relapsed or refractory LBCL represent one of the highest unmet need populations in lymphoma and require timely access to effective therapies
• If approved, this outpatient-ready regimen could enable access to care in the community setting, where most US patients receive treatment

Basel, June 18, 2026 - Roche (SIX: RO, ROP; OTCQX: RHHBY) announced today that the US Food and Drug Administration (FDA) has accepted the company’s supplemental Biologics License Application (sBLA) for Lunsumio VELO (mosunetuzumab), as a subcutaneous formulation, in combination with Polivy (polatuzumab vedotin) for the treatment of adult patients with relapsed or refractory large B-cell lymphoma (LBCL), including diffuse large B-cell lymphoma (DLBCL), after at least one prior line of systemic therapy. The FDA is expected to make a decision on approval by 9 February 2027.

The sBLA acceptance is based on results from the phase III SUNMO study. At a median follow-up of 23.2 months, the Lunsumio VELO and Polivy combination demonstrated a 59% reduction in risk of disease progression or death (progression-free survival [PFS]) compared to MabThera/Rituxan (rituximab), gemcitabine and oxaliplatin (R-GemOx) (hazard ratio [HR] 0.41, 95% confidence interval [CI]: 0.28–0.61; p<0.0001) and a three-times longer median PFS at 11.5 months (95% CI: 5.6-17.6), compared to 3.8 months for R-GemOx (95% CI: 2.9-4.1).¹ The safety profile of the Lunsumio and Polivy combination was consistent with the known profiles of the individual study medicines.¹ The incidence of cytokine release syndrome events (CRS) in the Lunsumio VELO plus Polivy arm was low, occurring in one in four patients, with less than 5% of patients experiencing Grade 2 or 3 CRS events.¹

Updated data were presented recently at the American Society of Clinical Oncology Annual Meeting and the European Hematology Association Congress, which showed that with longer follow-up, this treatment combination continued to demonstrate clinical benefit in PFS, particularly in the second-line setting, with no new safety signals.^2,3

“Relapsed or refractory large B-cell lymphoma is an aggressive disease thereby representing one of the highest unmet needs in lymphoma care,” said Levi Garraway, MD, PhD, Roche’s Chief Medical Officer and Head of Global Product Development. “If approved, this Lunsumio/Polivy combination could provide an important chemotherapy-free, outpatient-ready option to help improve outcomes in this setting.”
