Study description
This study is done to test a drug called ivosidenib in combination with durvalumab and gemcitabine/cisplatin in participants with a type of severe bile duct cancer (cholangiocarcinoma) that cannot be treated with surgery. Bile ducts are tiny tubes carrying bile from the liver to the intestine. Bile helps to digest fats in food. In several types of cancer such as cholangiocarcinoma, an abnormal (mutated) form of a protein called isocitrate dehydrogenase 1 (IDH1) is present in the tumor cells due to gene changes called mutations. This leads to the overproduction of 2-hydroxyglutarate (2-HG), a substance that is normally present in cells at low levels. Too much 2-HG impairs normal cell functioning and may cause them to become tumor cells.
Ivosidenib is a drug that blocks the activity of abnormal IDH1 proteins, which reduces 2-HG levels in tumor cells back to normal levels.
Researchers believe that combining ivosidenib with other approved treatments called durvalumab and gemcitabine/cisplatin might help treat these cancers better and improve the lives of people who have them.
The main goals of this study are:
Part 1:
- To look at the safety and tolerability of ivosidenib in combination with durvalumab and gemcitabine/cisplatin and to find the best (recommended) dose for this combination.
Part 2:
- To see how well ivosidenib in combination with durvalumab and gemcitabine/cisplatin works in treating the tumor.
- Ivosidenib
- Durvalumab (for the first 8, 21-day, cycles)
- Gemcitabine (for the first 8, 21-day, cycles)
- Cisplatin (for the first 8, 21-day, cycles)
- Durvalumab (starting from cycle 9)
- Ivosidenib Recommended Combination Dose (RCD)
- S095031-210
Eligibility Criteria
Eligible age for the study
Sex
Male/FemaleAccepts Healthy Volunteers
NoTo take part, participants have to:
- Be adults aged 18 or older.
- Have a documented IDH1 mutation in their tumor.
- Have cholangiocarcinoma that has spread to nearby areas (locally advanced) or other organs (metastatic) in the body and cannot be removed by surgery.
- Have adequate bone marrow (the spongy tissue inside bones where blood cells are made), liver, and kidney function.
Participants cannot take part in the study if:
- Their cancer has spread to the brain, requiring treatment with steroids.
- They have previously received treatment for their advanced, unresectable or metastatic cancer.
- They have previously received immune therapy.
How is the study designed?
Participants receive the ivosidenib, durvalumab, and gemcitabine/cisplatin combination to assess safety.
Participants take two 250 mg tablets by mouth once a day, every day.
Participants receive 1500 mg of durvalumab through an IV (intravenous) drip every 3 weeks, for the first 8 cycles, each cycle lasting 21 days.
Participants receive 1000 mg/m² of gemcitabine through an IV (intravenous) drip on days 1 and 8 of each 21-day cycle, for up to 8 cycles.
Participants receive 25 mg/m² of cisplatin through an IV (intravenous) drip on days 1 and 8 of each 21-day cycle, for up to 8 cycles.
Starting from cycle 9, participants receive 1500 mg of durvalumab through an IV (intravenous) drip every 4 weeks. Each cycle from cycle 9 onward lasts 28 days.
Participants receive different doses of the ivosidenib, durvalumab, and gemcitabine/cisplatin combination to find the recommended dose.
Participants receive 1500 mg of durvalumab through an IV (intravenous) drip every 3 weeks, for the first 8 cycles, each cycle lasting 21 days.
Participants will receive 1000 mg/m² of gemcitabine through an IV (intravenous) drip on days 1 and 8 of each 21-day cycle, for up to 8 cycles.
Participants will receive 25 mg/m² of cisplatin through an IV (intravenous) drip on days 1 and 8 of each 21-day cycle, for up to 8 cycles.
Starting from cycle 9, participants will receive 1500 mg of durvalumab through an IV (intravenous) drip every 4 weeks. Each cycle from cycle 9 onward will last 28 days.
Combination Dose (RCD) Participants will take the recommended combination dose of ivosidenib by mouth once a day, every day during the treatment.
