27 de outubro de 2026 atualizado por: Hutchmed

A Randomized, Double-Blind, Placebo-Controlled, Multicenter Phase III Study to Evaluate the Efficacy and Safety of HMPL-306 in Participants With Postoperative Residual or Recurrent Grade 2 Glioma Harboring IDH1 or IDH2 Mutations

This study is a randomized, double-blind, placebo-controlled, multicenter Phase III clinical trial evaluating the efficacy and safety of HMPL-306 in participants with postoperative residual or recurrent grade 2 gliomas carrying IDH1 or IDH2 mutations.

Descrição detalhada

This study plans to enroll approximately 210 participants with postoperative residual or recurrent grade 2 astrocytoma or oligodendroglioma carrying IDH1 or IDH2 mutations who have previously received only surgical treatment.

Participants meeting all enrollment eligibility criteria will be randomized in a 1:1 ratio to receive HMPL-306 250 mg or placebo matched to HMPL-306 administered orally once daily (QD). Participants will continue to receive study drug treatment in 28-day cycles until BIRC-confirmed PD, death, occurrence of intolerable toxicity, et al, whichever occurs first.

Participants in the placebo group with BIRC-confirmed PD, after evaluation, may cross over to the HMPL-306 group to receive HMPL-306 treatment.

Exclusion Criteria:

  1. Previously received any other anti-glioma treatment except for surgery, including chemotherapy, radiotherapy, targeted therapy, immunotherapy, or biological therapy, etc.;
  2. Participants assessed by the investigator as having high-risk factors, including but not limited to tumor involvement of the brainstem, or uncontrolled epilepsy;
  3. Participants with concurrent other malignant tumors or a history of other malignant tumors within 5 years prior to randomization (excluding cured basal or squamous cell carcinoma of the skin, carcinoma in situ of the cervix, and ductal carcinoma in situ of the breast, etc.);
  4. Women who are pregnant (positive pregnancy test before medication) or breastfeeding;
