Tirzepatide Continues to Perform; Positive Ph3 SURPASS-3 and SURPASS-5 Topline Results
Lilly announced positive topline results from the Ph3 SURPASS-3 (vs. degludec) and SURPASS-5 (add-on to glargine U100) trials evaluating the safety and efficacy of three tirzepatide doses (5mg/10mg/15mg). Recall, Lilly announced results from the first Ph3 tirzepatide study, SURPASS-1 (tirzep in treatment-naive patients), in December 2020. According to the press release, the 15mg dose of tirzepatide reduced A1C by -2.4% and weight by -12.9kg in the SURPASS-3 trial. In SURPASS-5, patients observed an average A1C reduction of -2.6% and weight loss of -10.9kg. Full results from SURPASS-3 and SURPASS-5 are scheduled to be presented at ADA 2021 (June 25-29). Below, FENIX provides an overview of the topline SURPASS data as well as updated thoughts on the tirzepatide market impact.
