AbbVie (NYSE: ABBV), a global biopharmaceutical company, today announced results from two Phase 2 clinical trials evaluating its investigational selective JAK1 inhibitor, ABT-494, in patients with inadequate response to either methotrexate or TNF inhibitors. The clinical trials, BALANCE-I and BALANCE-II, achieved ACR20 at week 12 across all dose levels, except the lowest dose in BALANCE-II. BALANCE-I and BALANCE-II evaluated patients with moderate to severe rheumatoid arthritis with inadequate responses to prior anti-TNF (TNF-IR) or methotrexate (MTX-IR) treatment, respectively.
"We believe ABT-494 has the potential to become a best-in-class therapy, particularly in the most challenging patient population of TNF-inadequate responders," said Michael Severino, M.D., executive vice president, research and development and chief scientific officer, AbbVie. "We are encouraged by the results of our Phase 2 studies and we will advance ABT-494 to Phase 3 studies with a once-daily formulation."
