Breakthrough Hope for Marginal Zone Lymphoma Patients: Positive Results from Abivertinib Clinical Trial

Sorrento Therapeutics, Inc. is pleased to announce the exciting results of the China phase IIa study of Abivertinib in the treatment of Patients with Relapsed/Refractor Marginal Zone Lymphoma (MZL). Abivertinib, a mutant EGFR and BTK dual inhibitor, showed promising outcomes with an impressive objective response rate (ORR) of 59.3%. This exceeds the ORR of the first approved treatment of R/R MZL, Ibrutinib.

To date, no severe bleeding, arrhythmia, or hypertension were observed in patients on Abivertinib treatment. These encouraging outcomes have led to an agreement with the NMPA, with plans to initiate a pivotal phase III registration study. With the potential for Abivertinib to be an effective treatment option for both Resistant EGFR mutant positive non-small cell lung cancer and R/R MZL, Sorrento is confident Abivertinib has great potential in the fight against cancer.
