Odronextamab setback sees Genmab/Abbvie pull ahead

Snippets

Presentation at Ash of clinical data for odronextamab, the Regeneron anti-CD20 bispecific that this week went on partial US clinical hold, had been greeted positively, spurred by generous praise from the study’s primary investigator. Dr Rajat Bannerji, from Rutgers Cancer Institute of New Jersey, said odronextamab had achieved durable complete responses, with an “acceptable risk-benefit profile”. But the hold might come as no surprise to those paying close attention to the data: 45% of patients suffered serious adverse events related to odronextamab, and five deaths were deemed treatment-related. The surprising part of the hold is that it was said to have been implemented to cut incidence of grade 3 or higher cytokine release syndrome. At this severity CRS occurred in just 10 of 136 lymphoma subjects in the trial, said Dr Bannerji, and no deaths were due to CRS. Some might now bemoan the odronextamab setback as bad news for patients, but biopharma’s anti-CD20 bispecific pipeline is bursting at the seams, and Genmab/Abbvie’s epcoritamab looks to be pulling ahead as best in class. That patients have been spared a toxic therapy and could soon face numerous better options should be welcomed.
