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.
Ivosidenib is approved in the United States and in EU for the treatment of advanced or metastatic CCA; this study is being conducted to conslidate the data related to the safety, efficacy, and impact on quality of life for patients. This is an open-label, single-arm study of ivosidenib, which means that all patients meeting eligibility criteria will receive two 250 mg ivosidenib tablets, totaling 500mg of drug, to be taken orally, once daily, for 28 consecutive days, also referred to as one cycle. Additional cycles can continue as long as clinical benefit is confirmed by an investigator, and consent is maintained. There will be a screening visit, study visit on day 1 of each cycle, withdrawal visit within 42 days of stopping treatment, and a follow-up visit every 6 months for up to 18 months after stopping treatment. This results in a minimum of 6 study visits for the completion of one 28-day cycle of ivosidenib. One additional study visit will be added on day one of each additional cycle of treatment. Study visits will include an electrocardiogram (ECG), physical exam, tumor assessment, according to local practive at a given site and blood and urine analyses. If at any point ivosidenib is made available as a medical prescription at the patient's site, patients will be withdrawn from the study treatment and patients will be followed to collect data on overall survival.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).
Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
