Brief summary: Phase 1: Dose escalation study (Phase Ia)

Main purpose:

Evaluate the safety and tolerability of BIO-008 in patients with advanced solid tumors, and determine the maximum tolerable dose (MTD) and dose limiting toxicity (DLT) of BIO-008.

Secondary purpose:

Evaluate the pharmacokinetic (PK) characteristics of BIO-008;

Evaluate the immunogenicity of BIO-008.

Exploratory purposes:

Preliminary evaluation of the anti-tumor activity of BIO-008 (if available);

Detect the expression of CLDN18.2 in tumor tissue and explore its correlation with BIO-008 anti-tumor activity indicators (only applicable to subjects who can provide fresh or archived tumor tissue samples before the first administration).

Phase 2: Dose Extension Study (Phase Ib)

Main purpose:

• Preliminary evaluation of ORR of BIO-008 in patients with CLDN18.2 positive advanced gastric cancer or gastroesophageal junction cancer (GC/GEJ), pancreatic cancer (PC) and other solid tumors;

Determine the recommended dose for clinical phase II (RP2D).

Secondary purpose:

Evaluate the safety and tolerability of BIO-008;

Evaluate the PK characteristics of BIO-008;

Evaluate the immunogenicity of BIO-008;

• Evaluate other anti-tumor activity indicators of BIO-008 in patients with CLDN18.2 positive advanced gastric cancer or gastroesophageal junction cancer, pancreatic cancer and other solid tumors;

Evaluate the correlation between the anti-tumor activity of BIO-008 and the expression of CLDN18.2.
