Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SEQUENTIAL

Arm && Interventions

Group	Intervention	Description
Study treatment	GNC-038	Participants receive GNC-038 as intravenous infusion for the first cycle (2 weeks). Participants with clinical benefit could receive additional treatment for more cycles. The administration will be terminated because of disease progression or intolerable toxicity occurring or other reasons.

Primary Outcome Measures

Name	Time	Method
Maximum tolerated dose (MTD) or Maximum dose (MAD)	Up to 14 days after the first dose	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.
Recommended dose for Phase II clinical studies (RP2D)	Up to 14 days after the first dose	The RP2D is defined as the dose level chosen by the sponsor (in consultation with the investigators) for phase II study, based on safety, tolerability, efficacy, PK, and PD data collected during the dose escalation study of GNC-038.
Adverse Events during Treatment (TEAE)	Up to approximately 24 months	TEAE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally emerging, or any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition during the treatment of GNC-038. The type, frequency and severity of TEAE will be evaluated during the treatment of GNC-038.
Dose limiting toxicity (DLT)	Up to 14 days after the first dose	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).

Secondary Outcome Measures

Name	Time	Method
Adverse Events of Special Interest (AESI)	Up to approximately 24 months	AESI is an event of scientific and medical interest specific to the sponsor's product or research project.
AUC0-T	Up to approximately 24 months	Blood concentration - Area under time line.
disease control rate (DCR)	Up to approximately 24 months	Number of patients showing Complete Response (CR) or Partial Response (PR) based on RECIST for the best response.; Number of patients showing Complete Response (CR, disappearance of all target lesions) or Partial Response (PR, at least a 30% decrease in the sum of longest diameter of target lesions taking as reference the baseline sum longest diameter) based on RECIST Criteria Version 1.0 (assessed by CT and/or MRI) for the best response.
Tmax	Up to approximately 24 months	Time to maximum serum concentration (Tmax) of GNC-038 will be investigated.
T1/2	Up to approximately 24 months	Blood concentration - Area under time line.
anti-drug antibody (ADA) in Ⅰa	Up to approximately 24 months	Frequency and titer of anti-GNC-038 antibody (ADA).
Cmax	Up to approximately 24 months	Maximum serum concentration (Cmax) of GNC-038 will be investigated.
AUC0-INF	Up to approximately 24 months	Blood concentration - Area under time line.
DOR (Duration of Response)	Up to approximately 24 months	The DOR for a responder is defined as the time from the participant's initial objective response to the first date of either disease progression or death, whichever occurs first.
progression-free survival (PFS)	Up to approximately 24 months	The PFS is defined as the time from the participant's first dose of GNC-038 to the first date of either disease progression or death, whichever occurs first.
