Potential Sanofi Bs-Aspart US Regulatory Strategy; New Interchangeability Trial

A new trial evaluating Sanofi’s biosimilar aspart (SAR341402) has been observed on CT.gov. The trial, called GEMELLI X, is an open-label, crossover design comparing SAR341402 vs. NovoLog in 184 T1DM adults who are also on glargine U100. The name of Sanofi’s Ph3 program is clever in that Gemelli is a type of pasta derived from the Italian word for “twins.” The “X” in this trial appears to reference the crossover design. Below, FENIX provides thoughts on the trial as well as insight into Sanofi’s potential strategy to delay filing until after March 23, 2020 thereby allowing for regulatory submission via the 351k biosimilar pathway.
