Roivant unveils latest spinout as Pfizer entrusts JAK1/TYK2 to Priovant

In November, Pfizer disclosed it’s spun out the Phase II dual JAK1/TYK2 inhibitor to a startup formed in collaboration with an unnamed, experienced partner.

We now know who the partner is. And as Pfizer and Roivant officially take the wraps off Priovant Therapeutics, the companies reveal that they have started two registrational trials of the drug, brepocitinib, as part of a broader plan to develop a big, first-in-class franchise spanning multiple orphan and specialty autoimmune diseases.
