Biogen is approaching a pivotal moment as it anticipates data from the TOPAZ-1 and TOPAZ-2 Phase 3 clinical trials evaluating the drug litifilimab for lupus, scheduled for the first half of December. According to STAT reporter Adam Feuerstein, this upcoming readout represents more than just a standard drug evaluation.

Strategic Stakes

The impending results serve as a major test for the R&D revamp and growth strategy implemented by CEO Chris Viehbacher since taking the helm in 2022. Because the company previously experienced a positive Phase 3 outcome with another lupus drug called dapirolizumab over two years ago, expectations and risks are both running high for this new portfolio readout.
