NCT ID NCT06127407

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This Phase 3 trial tests ivosidenib, a daily pill that targets a specific genetic mutation (IDH1), in 136 adults with advanced or metastatic conventional chondrosarcoma that cannot be surgically removed. Participants are randomly assigned to receive either ivosidenib or a placebo. The main goal is to see if the drug delays cancer progression, especially in lower-grade tumors.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Ivosidenib
What this could lead to
If successful, this could provide a targeted treatment option to slow tumor growth in people with a rare bone cancer that has few effective therapies.
What could go wrong
This is an early Phase 3 trial with only 136 participants, so results may not apply to all patients. The drug may not improve survival or could cause side effects.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Have a histopathological diagnosis (fresh or banked tumor biopsy sample collected within the last 3 years) consistent with locally advanced or metastatic conventional chondrosarcoma Grades 1, 2, or 3 and not eligible for curative resection. * Have at least one BICR-confirmed measurable lesion as defined by RECIST v1.1. Participants who have received prior radiation therapy are eligible provided measurable disease falls outside of the treatment field or within the field and has shown ≥20% growth in size since post-treatment assessment. * Have received 0 or 1 prior systemic treatment regimen in the advanced/metastatic setting for chondrosarcoma. * Have radiographic progression/recurrence of disease according to RECIST v1.1 defined as: 1. Radiographic progression of disease (local and/or distant) documented by 2 imaging assessments performed no more than 6 months (±2 weeks) apart within 12 months before randomization. OR 2. Any recurrence of disease (local and/or distant) after complete surgical resection and documented by imaging within 6 months (±2 weeks) before randomization. * Have documented IDH1 gene-mutated disease (from a fresh tumor biopsy or the most recent banked tumor tissue available that was sourced from either a primary or metastatic tumor lesion) based on central laboratory testing (R132C/L/G/H/S mutation variants tested) * Have recovered from any clinically relevant sequelae and toxic effects of any prior surgery, radiotherapy, or other therapy intended for the treatment of cancer. Exclusion Criteria: * Are unable to swallow oral medication. * Pregnant or lactating women. * Are participating in another interventional study at the same time; participation in noninterventional registries or epidemiological studies is allowed. * Have received prior therapy with an IDH1 inhibitor * Have received systemic anticancer therapy \<2 weeks prior to randomization (for investigational or immune-based anticancer therapy \<4 weeks). * Have received radiotherapy \<2 weeks prior to randomization. * Have known symptomatic brain metastases requiring steroids \>10 mg per day prednisone (or equivalent). Participants with previously diagnosed brain metastases are eligible if they have completed their treatment and have recovered from the acute effects of radiation therapy or surgery prior to randomization, have discontinued or reduced corticosteroid treatment \<=10 mg per day for these metastases for at least 4 weeks and have radiographically stable disease of brain lesions for at least 3 months prior to randomization. * Have a history of another primary cancer, with the exception of: a) curatively resected non-melanoma skin cancer; b) curatively treated carcinoma in situ; or c) pT1-2 prostatic cancer Gleason score \<6 or d) participant is free of other primary solid or liquid tumor for ≥ 1 year prior to the start of study treatment and, in the opinion of the Investigator, the disease will not affect participant's outcome in the setting of current chondrosarcoma diagnosis. * Have had major surgery within 4 weeks prior to randomization. * Have significant active cardiac disease within 6 months prior to randomization, including New York Heart Association (NYHA) Class III or IV congestive heart failure; myocardial infarction; unstable angina; and/or stroke. * Have LVEF \<40% by ECHO scan (or by other methods according to institutional practice) obtained within 28 days prior to randomization. * Have a heart-rate corrected QT interval (using Fridericia's formula) (QTcF) ≥ 450 msec or other factors that increase the risk of QT prolongation or arrhythmic events (eg, heart failure, hypokalemia, family history of long QT interval syndrome). Participants with a bundle branch block combined with a prolonged QTcF interval may be permitted based on local cardiology assessment. * Have known medical history of progressive multifocal leukoencephalopathy (PML).
