Brief Summary:
This is first-in-human, open-label, multi-center, dose-escalation (phase Ia) and cohort expansion (phase Ib) phase I study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamic, immunogenicity, and antitumor activities of IMM40H in patients with advanced malignancies including solid tumor and hematological malignancies.

Condition or disease Intervention/treatment Phase
Tumor Drug: IMM40H Phase 1

Detailed Description:

This study will include 16~27 patients with advanced malignancies that have progressed after or have no response to previous standard treatments or for whom no standard treatments are available (including but not limited to melanoma, nasopharyngeal cancer, thymoma, RCC, colorectal cancer, non-small cell lung cancer (NSCLC), glioblastoma, astrocytoma, ovarian cancer, AML, and lymphoma). The primary objective is to determine the maximum tolerated dosage (MTD) or recommended dose for expansion (RDE) by observing the safety and tolerability of IMM40H monotherapy.

The adjusted "3 + 3" design will be adopted in this trial for dose escalation, with the starting dose of IMM40H at 0.3 mg/kg and the temporary maximum dose at 20 mg/kg. In the dose-escalation stage, a total of 5 dose levels will be designed:0.3, 1, 3, 10, 20 mg/kg, to determine MTD . For each subject in each dose group, the dose will be gradually increased according to the dose-escalation rules, and the observation period for dose-limiting toxicity (DLT) will be set to be 28 days after the first dose.

Patients with CD70-positive malignancies to further evaluate the safety, PK characteristics, immunogenicity, and anti-tumor activity or preliminary efficacy of IMM40H dosing at MTD.
