Brief Summary

In this study, the safety, tolerability and preliminary effectiveness of GNC-039 in patients with relapsed/refractory or metastatic glioma or other solid tumors will be investigated to assess the dose-limiting toxicity (DLT), maximum tolerated dose (MTD) or maximum administered dose (MAD) for MTD is not reached of GNC-039.

Conditions

Recurrent Glioma; Solid Tumor

Outcome Measures

Primary Outcomes (3)

• Dose limiting toxicity (DLT)

  DLTs are assessed according to NCI-CTCAE v5.0 during the first cycle and defined as occurrence of any of the toxicities in DLT definition if judged by the investigator to be possibly, probably or definitely related to study drug administration.

  Up to 14 days after the first dose of GNC-039

• Maximum tolerated dose (MTD) or maximum administrated dose (MAD)

  In the dose increment stage, the highest dose whose estimated DLT rate is closest to the target DLT rate but does not exceed the upper bound of the equivalent interval of DLT rate is selected as MTD.

  Up to 14 days after the first dose of GNC-039

• Treatment-Emergent Adverse Event (TEAE)

  The incidence and severity of adverse events (TEAE) during treatment were graded according to the National Cancer Institute Standard for Common Terminology for Adverse Events (NCI-CTCAE, v5.0).

  Up to approximately 24 months

Secondary Outcomes (12)

• Drug-related Adverse Events

  Up to approximately 24 months

• Cmax: Maximum serum concentration of GNC-039

  Up to 14 days after the first dose of GNC-039

• Tmax: Time to maximum serum concentration (Tmax) of GNC-039

  Up to 14 days after the first dose of GNC-039

• T1/2: Half-life of GNC-039

  Up to 14 days after the first dose of GNC-039

• AUC0-inf: Area under the serum concentration-time curve from time 0 to infinity

  Up to 14 days after the first dose of GNC-039
