Taken continuously until BICR-confirmed disease progression, unacceptable toxicity, confirmed pregnancy, death, withdrawal of consent, lost to follow-up, or the Sponsor ends the study (estimated average treatment duration of two years).

Taken continuously until BICR-confirmed disease progression, unacceptable toxicity, confirmed pregnancy, death, withdrawal of consent, lost to follow-up, or the Sponsor ends the study (estimated average treatment duration of two years). Participants randomized to the placebo arm who experience BICR-confirmed disease progression and meet the crossover eligibility criteria will be given the opportunity to cross over and receive ivosidenib.

Provided as tablets, taken orally as two 250mg tablets once daily.

Study CL3-95031-007 (CHONQUER) is a Phase 3, international, multicenter, double-blind, randomized, placebo-controlled study of orally administered ivosidenib. Participants are required to have a histopathological diagnosis consistent with isocitrate dehydrogenase-1 (IDH1) gene-mutated, locally advanced or metastatic conventional chondrosarcoma Grades 1, 2, or 3 and not eligible for curative resection. IDH1 mutant status will be determined during pre-screening/screening phase. Participant must have radiographic progression/recurrence of disease according to Response Evaluation Criteria in Solid Tumors (RECIST v1.1) and have received 0 to 1 prior systemic treatment regimen in the advanced/metastatic setting for conventional chondrosarcoma. The primary endpoint is progression-free survival (PFS) in Grades 1 and 2 participants. Key secondary endpoints are PFS in all randomized participants, overall survival (OS) in Grades 1 and 2 participants, and OS in all randomized participants.

Participants who meet enrollment criteria will be randomized 1:1 to receive oral ivosidenib 500mg once daily, or a matching placebo once daily.

Qualified scientific and medical researchers can request access to anonymized patient-level and study-level clinical trial data.

Access can be requested for all interventional clinical studies:

* used for Marketing Authorization (MA) of medicines and new indications approved after 1 January 2014 in the European Economic Area (EEA) or the United States (US).
* where Servier is the Marketing Authorization Holder (MAH). The date of the first MA of the new medicine (or the new indication) in one of the EEA Member States will be considered for this scope.

In addition, access can be requested for all interventional clinical studies in patients:

* sponsored by Servier
* with a first patient enrolled as of 1 January 2004 onwards
* for New Chemical Entity or New Biological Entity (new pharmaceutical form excluded) for which development has been terminated before any Marketing authorization (MA) approval.

From randomization until BICR confirmed progressive disease or death due to any cause, whichever occurs first

From randomization until confirmed CR or PR

The time from date of first documented confirmed CR or confirmed PR to date of first documented disease progression or death due to any cause.

The time from the date of randomization to date of first documented confirmed complete response (CR) or confirmed partial response (PR).

The EORTC-QLQ-C30 contains 30 items across 5 functional scales, 9 symptom scales and a global health status. Raw scores are converted to scales ranging from 0 - 100. For the functional scales and global health status, the higher score represents the better functioning or global health status; for the symptom scales, the higher score represents an increase in symptoms.

The 5-level EQ-5D-5L scores range from 5 to 25 with a higher number representing a worse health status.

The PROMIS Item Bank v1.0 Physical Function with Mobility Aid - Short Form questionnaire score ranges from 1 "Unable to do" to 5 "Can do without a problem" for each capability.
