Agios Announces the Randomized Phase 3 ClarIDHy Trial of TIBSOVO® (ivosidenib) Achieved its Primary Endpoint in Previously Treated IDH1 Mutant Cholangiocarcinoma Patients

World News: . []

CAMBRIDGE, Mass., May 15, 2019 (GLOBE NEWSWIRE) -- Agios Pharmaceuticals, Inc. (NASDAQ:AGIO), a leader in the field of cellular metabolism to treat cancer and rare genetic diseases, today announced that the global Phase 3 ClarIDHy trial of TIBSOVO (ivosidenib) in previously treated cholangiocarcinoma patients with an isocitrate dehydrogenase 1 (IDH1) mutation met its primary endpoint. Treatment with TIBSOVO demonstrated a statistically significant improvement in progression-free survival (PFS) by independent radiology review compared with patients who received placebo. The safety profile observed in the study was consistent with previously published data.

A full analysis of the ClarIDHy trial will be submitted for presentation at the European Society for Medical Oncology Congress taking place in Barcelona, Spain from September 27-October 1, 2019. The company plans to submit a supplemental new drug application for TIBSOVO in previously treated IDH1 mutant cholangiocarcinoma by the end of 2019.

“Advanced cholangiocarcinoma is a life-threatening disease with no currently approved treatment options,” said Chris Bowden, M.D., chief medical officer at Agios. “The data from the ClarIDHy Phase 3 trial demonstrate the clinically significant benefit of TIBSOVO in patients with this challenging disease who harbor the IDH1 mutation. We are committed to working with regulators to bring this potential treatment option to patients as quickly as possible. We thank the patients and physicians who participated in the ClarIDHy study, without whom this important advancement would not be possible.”

TIBSOVO is not approved in any country for the treatment of patients with advanced cholangiocarcinoma.

TIBSOVO is indicated for the treatment of acute myeloid leukemia (AML) with a susceptible isocitrate dehydrogenase-1 (IDH1) mutation as detected by an FDA-approved test in:

If differentiation syndrome is suspected, initiate dexamethasone 10 mg IV every 12 hours (or an equivalent dose of an alternative oral or IV corticosteroid) and hemodynamic monitoring until improvement. If concomitant noninfectious leukocytosis is observed, initiate treatment with hydroxyurea or leukapheresis, as clinically indicated. Taper corticosteroids and hydroxyurea after resolution of symptoms and administer corticosteroids for a minimum of 3 days. Symptoms of differentiation syndrome may recur with premature discontinuation of corticosteroid and/or hydroxyurea treatment. If severe signs and/or symptoms persist for more than 48 hours after initiation of corticosteroids, interrupt TIBSOVO until signs and symptoms are no longer severe

Interrupt TIBSOVO if QTc increases to greater than 480 msec and less than 500 msec. Interrupt and reduce TIBSOVO if QTc increases to greater than 500 msec. Permanently discontinue TIBSOVO in patients who develop QTc interval prolongation with signs or symptoms of life-threatening arrhythmia.

Because many drugs are excreted in human milk and because of the potential for adverse reactions in breastfed children, advise women not to breastfeed during treatment with TIBSOVO and for at least 1 month after the last dose.
