Safety, Tolerability, and Pharmacokinetics of MW11 in Patients With Advanced Solid Tumors
Study Details
Study Description
Brief Summary
This is a phase Ia, single-center, open label, dose escalation clinical study to evaluate the safety, tolerability, pharmacokinetics, immunogenicity and anti-tumor efficacy of MW11 (a recombinant humanized anti-PD-1 monoclonal antibody) for injection in patients with advanced solid tumors.

Phase 1 |
Detailed Description
The enrollment mainly depends on "3+3" principle. A total of 3 or 4 dose groups will be evaluated during the dose escalation period: 1, 3, 10 mg/kg, and maybe an additional fixed dose (e.g., to evaluate 200 mg or other fixed dose as RP2D). The drug is scheduled to be administrated Q3W. Actual dose increments or dosing frequency may be adjusted according to PK data and safety of MW11. Safety, tolerability, and DLT will be assessed within 3 weeks (21 days) after initial administration. Anti-tumor efficacy will be assessed every 6 weeks during the first 24 weeks and every 12 weeks ever since. The study will be divided into screening period and treatment period. The drug administration will be continued until the investigators consider that the subjects will no longer benefit from the treatment, or the subjects meet intolerable toxicity, or the subjects withdraw the informed consent, or disease progression occurs.

Renal function: serum creatinine ≤ 1.5 times the upper limit of normal value (ULN) or creatinine clearance ≥ 50 mL/ min (Chockcroft-Gault formula was used for creatinine clearance).

Female subjects of reproductive age (before menopause and women after menopause within 2 years) must have negative blood pregnancy test results within 7 days before the first drug administration.
-
Subjects sign informed consent voluntarily, to make sure they understand the study and are willing to follow and able to complete all trial procedures.
Exclusion Criteria:
