A Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of CN1
A Phase I, Open Label, Multi-Center, Dose Escalation Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of CN1 in Patients With Advanced Solid Tumors or B-cell Lymphoma
Study Overview
Detailed Description
CN1 could promote T cell activation and cytokine secretion, thereby enhancing the function of CD4+ and CD8+ T cells, and could also regulate Treg cells, thus CN1 is considered to enhance the anti-tumor immune response and have potential antitumor activity.
In this multicenter, open-label, dose-escalation Phase I study six dose levels are planned. Participants will receive CN1 by IV infusion on Day 1 of each cycle (every 3 weeks). After completion of treatment cycles, the participant will be assessed by the Principal Investigator and/or Safety Monitoring Committee (SMC).

Experimental: Single Arm
Five planned CN1 dose levels of 0.03 mg/kg, 0.3 mg/kg, 1 mg/kg, 3 mg/kg, and 10 mg/kg. Subjects will receive CN1 by intravenous infusion (IV) on Day 1 (D1) of each cycle (once every 3 weeks per cycle). |
Participants will receive CN1 by IV infusion on Day 1 of each cycle (every 3 weeks).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
To determine dose-limiting toxicity (DLT), maximum tolerated dose (MTD), and/or recommended Phase II dose (RP2D) of CN1 administered to patients with advanced solid tumor or B-cell lymphoma.
Time Frame: 21 Days after the first dose i.e. starting dose level 0.03 mg/kg
|
DLT is measured in the observation period of 21 days after the first dose i.e. starting dose level 0.03 mg/kg.
if the enrolled subject does not experience a study drug related Grade 2 or higher adverse event (AE) per NCI-Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0, the subject will start to receive the next designated dose level of 0.3 mg/kg in the second 21 days dosing cycle.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
