Lilly/Incyte Plan sNDA for Baricitinib in Alopecia
Eli Lilly and and Incyte say they plan to file in the second half of this year a supplemental NDA for baricitinib in alopecia areata after reporting positive data from a second Phase 3 trial (BRAVE-AA1). They say the data are consistent with findings from the first Phase 3 clinical trial, BRAVE-AA2, announced earlier this year. “In both investigational trials, a statistically significant proportion of patients treated with baricitinib achieved the primary endpoint of hair regrowth across the two dosing regimens at Week 36 compared to patients treated with placebo,” they say.
Baricitinib is a once-daily, oral JAK inhibitor approved in the U.S. under the trade name Olumiant as a treatment for adults with moderate to severe rheumatoid arthritis. The proposed submission may face greater scrutiny due ongoing FDA safety concerns with JAK inhibitors (see earlier story). FDA recently extended the review period for a supplemental NDA for Olumiant (baricitinib) for treating adults with moderate to severe atopic dermatitis.
The drug class concerns arose from an FDA-required safety study when Pfizer’s Xeljanz (tofacitinib) was approved in 2012 for rheumatoid arthritis. In 2/2019 and 7/2019, FDA warned that interim trial results showed an increased risk of blood clots and death with the 10 mg twice daily dosage, and as a result, approved a Boxed Warning. The clinical trial is now complete and initial results show a higher occurrence of serious heart-related events and cancer in rheumatoid arthritis patients treated with both the 5mg and 10mg doses of tofacitinib compared to patients treated with a TNF inhibitor. FDA is awaiting additional results from the trial.
