Right as it gets a date with FDA, For­ma of­floads IDH1 in­hibitor to Rigel

An IDH1 in­hibitor on the cusp of an FDA de­ci­sion is chang­ing hands.

Wa­ter­town, MA-based For­ma Ther­a­peu­tics has long made it clear that olu­tasi­denib, its oral in­hibitor of mu­tant isoc­i­trate de­hy­dro­ge­nase 1, is a non-core pro­gram. So per­haps it’s lit­tle sur­prise that as the FDA ac­cepts its NDA, For­ma’s li­cens­ing the drug to Rigel Phar­ma­ceu­ti­cals in a $235 mil­lion deal.

Rigel is on­ly pay­ing $2 mil­lion of that up­front, but For­ma could col­lect an­oth­er $17.5 mil­lion soon if it meets cer­tain reg­u­la­to­ry, ap­proval and first com­mer­cial sales mile­stones. The rest is tied to fu­ture de­vel­op­ment and com­mer­cial work.
