UCB and Biogen: new post-hoc phase 3 analyses in lupus for dapirolizumab
UCB and Biogen reported post-hoc phase 3 analyses for dapirolizumab pegol in lupus. At week 48, 61.2% of patients on the drug showed a clinically meaningful response in at least half of their active organ domains, compared to 43.2% on placebo. The TRM-SLE tool, developed by an international group, was used for the first time in phase 3 data. Further validation is needed, and the tool was not a predefined endpoint.
