Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: PHASE1/PHASE2
• Total Enrollment: 15 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2018-10-10
• Study Completion Date: 2023-06-23

Brief Summary

This is a Phase 1+2, open-label, dose-escalation, and multidose study, aiming to investigate the safety, tolerability and pharmacokinetics of ZKAB001 (a fully human monoclonal antibody targeting the Programmed Death - Ligand 1 (PD-L1) membrane receptor on T lymphocytes and other cells of the immune system) administered every 14 days in subjects with limited stage of high-grade osteosarcoma of maintenance therapy after adjuvant chemotherapy.

Detailed Description

The study will consist of 4 periods: Screening (up to 28 days), Lead-in period (Day -28), Treatment (up to 24 cycles or 1 year, whichever occurs first), and Follow-up (up to 2 years). There will be a lead-in period on Day -28 for each dose escalation cohort in which the single-dose pharmacokinetics(PK) of ZKAB001 will be characterized prior to initiation of continuous dosing in the first cycle of treatment. The lead-in period duration, PK time-points, doses and/or regimens used in subsequent cohorts may be modified based on the exposure (AUC) observed during the lead-in period (although the number of PK samples will not be increased). Treatment of continuous dosing is up to 24 cycles or 1 year, until as per investigator's opinion, subjects experience disease progression (evaluated by RECIST 1.1), no clinical benefit, or intolerable toxicity. If investigators suspect subjects experience pseudoprogression or has evidence to prove "mixed response", subjects can continue to accept treatment as investigator decided.
