ES101 will be escalated in patients with advanced solid tumors.

Subjects with solid tumors will be treated with single-agent ES101 at either specified dose levels or RP2D.

ES101 is administered via intravenous infusion, once every 14 days, every 28 days as a treatment cycle.

ES101

The purpose of this study is to evaluate the safety, tolerance and Dose-Limiting Toxicity (DLT) of recombinant humanized PD-L1/4-1BB bispecific antibody (ES101) in patients with advanced solid tumors.

ES101 (INBRX-105; PDL1x4-1BB antibody) is a recombinant humanized bispecific IgG1 antibody targeting human PD-L1 and 4-1BB. This is an open-label, multicenter, dose-escalation and cohort expansion phase 1 clinical study to evaluate the safety and pharmacokinetic characteristics and preliminary anti-tumor activity of ES101 in patients with advanced malignant solid tumors whose disease has progressed despite standard therapy, or who has no further standard therapy, or who is unsuitable for available standard treatment options.

The MTD and/or RP2D of ES101 will be determined.

Adverse events will be assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 5.0.

Severity of adverse events will be assessed and assigned by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 5.0.

Area under the serum concentration time curve (AUC) of ES101 will be determined.

Maximum observed serum concentration (Cmax) of ES101 will be determined.

Trough observed serum concentration (Cmax) of ES101 will be determined.

Time to Cmax (Tmax) of ES101 will be determined.

Frequency of anti-drug antibodies (ADA) against ES101 will be determined.

Tumor response will be determined by the revised Response Evaluation Criteria in Solid Tumors version 1.1 (RECISTv1.1).

ES101 is administered via intravenous infusion, 0.3mg/kg，once every 14 days, every 28 days as a treatment cycle.

ES101 is administered via intravenous infusion, 1mg/kg，once every 14 days, every 28 days as a treatment cycle.

ES101 is administered via intravenous infusion, RP2D (to be determined)，once every 14 days, every 28 days as a treatment cycle.

The active ingredient of ES101 is a recombinant, humanized, bispecific IgG antibody that targets the human programmed death-ligand 1 (PD-L1) receptor and the human 4-1BB receptor.

The purpose of this study is to evaluate the safety, RP2D and PK/pharmacodynamic profile of ES101 monotherapy in patients with advanced NSCLC and to further evaluate the antitumor efficacy of ES101 in advanced malignant thoracic tumors, including NSCLC and SCLC.

Assess the relationship between ES101 exposure and efficacy/adverse events.

Assess PD-L1 receptor occupancy and cytokines

Assess PD-L1 expression status of tumor tissues
