Phase II Study Evaluating Ivosidenib Maintenance After SOC Adjuvant Chemotherapy in Curative mIDH1 Cholangiocarcinoma

Exclusion Criteria

• •1. Patient has a metastatic or R+ resected biliary tract cancer.
• •2. Patient received previous therapy with an IDH1 inhibitor.
• •3. Patient has known presence of tumors other than intrahepatic cholangiocarcinoma or a secondary tumor other than squamous or basal cell carcinomas of the skin or in situ carcinomas of the cervix which have been effectively treated. The sponsor decides to include patients who have received curative treatment and have been disease-free for at least 5 years.
• •4. Simultaneous, ongoing systemic immunotherapy, chemotherapy, or hormone therapy not described in the trial protocol.
• •5. Patient receives simultaneous treatment with a different anti-cancer therapy other than that provided for in the trial (excluding palliative radiotherapy only for symptom control).
• •6. Patient has a stage B cirrhosis according to Child-Pugh criteria (or worse) or cirrhosis (of any grade) with a history of hepatic encephalopathy or clinically significant ascites resulting from cirrhosis. Clinically significant ascites is defined as ascites resulting from cirrhosis requiring diuretics or paracentesis.
• •7. Patient has known allergic / hypersensitive reactions to at least one of the treatment components.
• •8. Patient has other serious illnesses or medical ailments within the last 12 months prior to the start of the trial.
• •9. Patient has a known presence of an active, uncontrollable infection.
• •10. Patient has QTc \> 480ms or other factors that, in the discretion of the investigator increase significantly the risk of QT prolongation or arrhythmic events (e.g. heart failure, hypokalemia, family history of long QT syndrome). NOTE: Medications that prolong the QT interval should be avoided, unless they can be transferred to other medication within ≥ 5 half-lives to dosing or unless the medications can be properly monitored during the study. (If equivalent medication is not available, QTc should be closely monitored).
• •11. Patient has active disseminated intravascular coagulation.
• •12. Patient has an active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
• •13. Patient has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial drug.
• •14. Patient has any other serious concomitant or medical condition that, in the opinion of the investigator, presents a high risk of complications to the patient or reduces the likelihood of clinical effect. NOTE: strong CYP3A4 inducers or sensitive CYP3A4 substrates with narrow therapeutic window should be avoided, unless they can be transferred to alternative medication within at least 5-half lives prior to dosing.
• •15. Female patient is pregnant or breast feeding or planning to become pregnant within and 6 months after the end of treatment.
• •16. Patient who has been incarcerated or involuntarily institutionalized by court order or by the authorities.
