Study Endpoints

Primary Endpoints

Number of Subjects with Dose Limiting Toxicities (DLTs)
Up to 28 days after first dose of study drug

DLT is defined as an adverse event (AE) that meets protocol defined DLT criteria during cycle 1 and is at least possibly related to study drug.

RP2D
From first dose of study drug to the time of progressive disease, assessed up to 24 months on average

Determine the Phase II recommended dose (RP2D) of HMPL-306 in patients with gliomas harboring IDH1 and/or IDH2 mutations based on a comprehensive assessment.

Secondary Endpoints

Maximum serum drug concentration
PK/PD weeks at screening through safety follow-up, assessed up to 24 months on average
Time to maximum concentration
PK/PD weeks at screening through safety follow-up, assessed up to 24 months on average
Area under the concentration-time curve (AUC)

Frequently asked questions about HMPL-306

What is HMPL-306 used for in gliomas harboring IDH1 and/or IDH2 mutations?

HMPL-306 is an investigational small molecule being studied for the treatment of gliomas harboring IDH1 and/or IDH2 mutations. It is currently in Phase 1 clinical development, with an active trial recruiting patients in China. The drug is not yet approved and remains under investigation for this indication.

What does HMPL-306 target?

HMPL-306 targets IDH1 and IDH2, which are enzymes involved in cellular metabolism. By inhibiting these mutant enzymes, the drug aims to address gliomas that harbor IDH1 and/or IDH2 mutations. This targeted approach is being evaluated in an ongoing Phase 1 clinical trial.

Who makes HMPL-306?

HMPL-306 is being developed by HUTCHMED (China) Limited, a biopharmaceutical company listed on the stock exchange under the ticker HCM. The company is conducting a Phase 1 clinical trial of HMPL-306 for the treatment of gliomas with IDH1 and/or IDH2 mutations.

What phase is HMPL-306 in?

HMPL-306 is in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities. The ongoing Phase 1 trial is actively recruiting participants to evaluate the drug's safety and efficacy in patients with gliomas harboring IDH1 and/or IDH2 mutations.

What clinical trials is HMPL-306 in?

HMPL-306 is being studied in a Phase 1 clinical trial registered as NCT07025018, titled 'Phase I Study of HMPL-306 for the Treatment of Gliomas With IDH1 and/or IDH2 Mutations'. This trial is recruiting 52 participants in China, with an age minimum of 18 years, and is open to all sexes.

Is HMPL-306 the same as HMPL-306 Regimen?

Yes, HMPL-306 is also known as HMPL-306 Regimen. Both names refer to the same investigational drug being developed by HUTCHMED (China) Limited for the treatment of gliomas harboring IDH1 and/or IDH2 mutations. The drug is currently in Phase 1 clinical trials.
