Clinical Trial Summary

The study is designed to evaluate the safety, tolerability, pharmacokinetic characteristics and anti-tumor activity of CN202 in adult subjects with locally advanced or metastatic solid tumor or hematologic malignancies


Description:

This is a multi-centre, open-label, Phase I/II study in adult subjects with locally advanced or metastatic solid tumor or hematologic malignancies. The study consists of three parts Phase Ia: Dose Escalation: This is a dose escalation for assessment of dose-limiting toxicities (DLT) at approximately four dose levels in subjects with locally advanced or metastatic solid tumor or hematologic malignancies. Phase Ib: Dose Expansion: To evaluate the safety, tolerability, pharmacokinetics, and preliminary efficacy of CN202, prior to determination of Maximum tolerated dose (MTD) Phase II: To further evaluate the safety, tolerance, pharmacokinetic characteristics, and anti-tumor activity of CN202 in subjects with select tumors. All subjects will receive the recommended Phase II dose of CN202. There will be 13 to 24 subjects enrolled in phase Ia, 12 to 40 subjects in phase Ib and 15 to 100 subjects in phase II

Histologically or cytologically diagnosed metastatic or locally advanced solid tumor or hematologic malignancy (unresectable), for whom no effective standard anti-tumor therapy existed or in the opinion of the Investigator have been considered ineligible for standard anti-tumor therapy at this stage, or are intolerant to standard anti-tumor therapy, or standard therapy had failed or the subject has refused standard anti-tumor therapy, or recurrent and progressing since last line anti-tumor therapy; 3. Representative tumor specimens in paraffin blocks (preferred) or at least 10 unstained slides, with an associated pathology report, requested at any time prior to study entry. Only tissue from core needle, punch, or excisional biopsy sample collection will be accepted. If archival tissue is insufficient or unavailable, the subjects may still be eligible upon discussion with Medical Monitor and approved by sponsor. 4.

Major organ surgery (excluding puncture biopsy) or significant trauma within 4 weeks prior to the first dose of study drug, or elective surgery during the trial; 6. Systemic application of corticosteroids (prednisone > 10 mg/day or equivalent) or other immunosuppressive agents within 14 days prior to the first dose of study drug; • Exceptions: topical, ocular, intra-articular, intranasal, inhaled corticosteroids, or short-term corticosteroids for prophylaxis (eg, contrast allergy prophylaxis). 7. Use of live attenuated vaccine within 4 weeks prior to the first dose of study drug; - Exception: Approved COVID-19 vaccine is allowed, but the last dose of COVID-19 vaccine should be administered 2 weeks prior to first dose of study drug; - For active subjects enrolled in this study, COVID-19 vaccination is allowed after 8 weeks treatment have been completed and the safety data have been obtained to make conclusion regarding the safety of the investigational product. 8. Adverse reactions prior to anti-tumor therapy that have not recovered to = Grade 1 assessed by CTCAE Version 5.0 (except for toxicities such as alopecia judged by the Investigator as no safety risk); 9. Clinically symptomatic metastases to the central nervous system (CNS) or meninges, or other evidence of uncontrolled metastases to the CNS or meninges of the subject, judged by the Investigator. Subjects are eligible if metastases have been treated, subjects are neurologically stable for at least four weeks and not requiring steroid therapy for at least one week prior to Cycle 1 Day 1. 10. Active infection and in current need of, or likely to need, intravenous anti-infective therapy; 11. History of immunodeficiency, including history of any positive test result for human immunodeficiency virus (HIV) antibody; 12. Active hepatitis B or hepatitis C infection: defined as having a positive hepatitis B surface antigen (HBsAg) test and/or detectable level of HBV DNA at Screening or hepatitis C infection defined as having a positive HCV antibody test followed by a positive HCV RNA test at Screening. HCV negative subjects are allowed to enrol. But in Phase Ib/II, the subjects with HBsAg+ but HBV DNA negative are allowed to be enrolled in HCC cohort with the use of antiviral therapy;
