Outcome Measures
Primary Outcome Measures
- Phase I: Dose limiting toxicity (DLT) [Up to 21 days after the first dose]
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.
- Phase I: Maximum tolerated dose (MTD) [Up to 21 days after the first dose]
MTD is defined as the highest dose level at which no more than 1 in 6 participants experienced a DLT during the first cycle .
- Phase I: Treatment-Emergent Adverse Event (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-035. The type, frequency and severity of TEAE will be evaluated during the treatment of GNC-035.
- Phase I: Recommended Phase II Dose (RP2D) [Up to 21 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-035.
- Phase II: Objective Response Rate (ORR) [Up to approximately 24 months]
ORR is defined as the percentage of participants, who has a CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions). The percentage of participants who experiences a confirmed CR or PR is according to RECIST 1.1.
Secondary Outcome Measures
- Phase I: Objective Response Rate (ORR) [Up to approximately 24 months]
ORR is defined as the percentage of participants, who has a CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions). The percentage of participants who experiences a confirmed CR or PR is according to RECIST 1.1.
- Progression-free survival (PFS) [Up to approximately 24 months]
The PFS is defined as the time from the participant's first dose of GNC-035 to the first date of either disease progression or death, whichever occurs first.
- Disease Control Rate (DCR) [Up to approximately 24 months]
The DCR is defined as the percentage of participants who has a CR, PR, or Stable Disease (SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease [PD: at least a 20% increase in the sum of diameters of target lesions and an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD]).
- Duration of Response (DOR) [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.
- Phase I: Complete Response (CR) [Up to approximately 24 months]
Complete response (CR) is defined as all tumor target lesions disappeared, no new lesions appeared, and tumor markers were normal for at least 4 weeks.
- Treatment-Emergent Adverse Event (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-035. The type, frequency and severity of TEAE will be evaluated during the treatment of GNC-035.

Patients who experience failure of at least one line of standard therapy. Patients with relapsed or refractory disease who were not or not suitable for other therapies as judged by the investigator.
Relapsed and refractory were defined as follows:
Relapse was defined as disease progression after 6 months of response to adequate treatment with at least one anti-CD20 monoclonal antibody.
Refractory was defined as refractory to anti-CD20 monoclonal antibody, failure to achieve remission after adequate treatment with anti-CD20 monoclonal antibody (combined chemotherapy or single agent), or disease progression during treatment or 6 months after completion of adequate treatment.
Among them, "anti-CD20 monoclonal antibody regimen adequate treatment" refers to the completion of the full cycle of anti-CD20 monoclonal antibody combined with chemotherapy according to the pathological type and disease stage, such as rituximab monotherapy at a dose of 375 mg/m2 per week for at least 4 injections. Progression during treatment required the completion of at least one cycle of anti-CD20 monoclonal antibody combined with chemotherapy or monotherapy if progression occurred during induction therapy. At least one dose was completed if progression occurred during maintenance therapy. "Response" included complete and partial responses.
