Roche announced data from a five-year follow-up of the pivotal phase III POLARIX study evaluating Polivy (polatuzumab vedotin) in combination with MabThera/Rituxan (rituximab), cyclophosphamide, doxorubicin and prednisone (R-CHP) in people with untreated diffuse large B-cell lymphoma (DLBCL).

Data were presented in an oral session at the 66th American Society of Hematology (ASH) Annual Meeting and Exposition, 7-10 December 2024 in San Diego, US. This latest analysis conducted after a median follow-up of 60.9 months, includes descriptive data on primary and secondary endpoints, as well as safety results.

“POLARIX was the first trial to elevate treatment standards for frontline diffuse large B-cell lymphoma in 20 years and we are additionally encouraged by the five-year follow-up results,” said Levi Garraway, MD, PhD, Roche’s Chief Medical Officer and Head of Global Product Development. “More than 38,000 people worldwide have been treated with Polivy in combination with R-CHP and these data continue to underscore its potential to improve outcomes for people diagnosed with this aggressive lymphoma.”

“Diffuse large B-cell lymphoma is a notoriously challenging cancer to treat, however, Polivy in combination with R-CHP has shown to be a critical advance for patients by helping to reduce relapse and disease progression,” said Gilles Salles, MD, PhD, Chief of Lymphoma Service, Division of Hematological Malignancies, Memorial Sloan Kettering Cancer Center, US. “The survival trend seen in this follow-up analysis reinforces the potential impact of frontline treatment with Polivy in combination with R-CHP and its role as a standard of care therapy.”

Polivy in combination with R-CHP is currently approved for the treatment of first-line (1L) DLBCL in more than 90 countries worldwide including the US, countries throughout the EU, the UK, Japan, Canada and China. Roche continues to work with health authorities around the world to bring this treatment regimen to even more patients.
