Study of Vorasidenib (AG-881) in Participants With Residual or Recurrent Grade 2 Glioma With an IDH1 or IDH2 Mutation (INDIGO)

Study description
The Indigo study is looking into a new treatment for a type of brain tumour called Grade 2 glioma. These tumours may come back or continue to grow, even after surgery. Researchers have discovered that many of these tumours have mutations (changes) in specific genes called IDH1 or IDH2. These mutations result in abnormal IDH proteins in the cancer cells that can help the tumour. Vorasidenib (also called AG-881) is a drug that is designed to block the abnormal IDH1 and IDH2 proteins in cancer cells. The aim of the study is to see if vorasidenib is safe and effective in stopping these tumours from growing. This research is important because, currently, there are limited treatment options for patients with this type of tumour who have already had surgery.

Eligibility Criteria
Eligible age for the study
Sex
Male/FemaleAccepts Healthy Volunteers
NoTo take part of the study, participants have to:
- be at least 12 years old (or 18 years old in Germany) and weigh at least 40 kg.
- have a specific type of brain tumor called oligodendroglioma or astrocytoma.
- have had surgery to remove the tumour at least one year ago but not more than five years ago.
- have a specific gene mutation (IDH1 or IDH2) in their tumour, confirmed through special tests.
- have a cancer that can be measured using MRI scans and doesn’t show extra growth.
- be generally healthy with well-functioning bone marrow (the spongy tissue inside bones where blood cells are made), liver and kidneys.
Participants cannot take part in the study if:
- they have received any cancer treatment other than surgery, like chemotherapy (treatment with medicines) or radiotherapy (treatment with radiation).
- they have an immediate need for chemotherapy or radiotherapy.
- their condition is assessed as high-risk by the doctor.
How is the study designed?
Participants receive vorasidenib 40 milligrams (mg) as tablets, to be taken by mouth once a day during time periods called “cycles”. One cycle lasts 28 days.
Participants receive placebo as tablets, to be taken by mouth once a day during time periods called “cycles”. One cycle lasts 28 days.
The placebo looks like vorasidenib but does not have any medicine in it.
