An Early Access Study of Ivosidenib in Patients With a Pretreated Locally Advanced or Metastatic Cholangiocarcinoma

Summary

A Phase 3b research study to consolidate the data that ivosidenib is safe and effective in adult patients with previously treated, locally advanced, or metastatic cholangiocarcinoma (CCA). All patients who meet inclusion criteria will be enrolled to receive ivosidenib tablets orally once daily for 28 day cycles, continuing as long as clinical benefit and consent for participation is maintained. There will be a minimum of 6 study visits from screening until the final follow-up, if one cycle of treatment is completed and consent is maintained through 18 months of follow-up. Each additional cycle completed will add one study visit, on the first day of each cycle.
