Overview
Brief Summary
This is an open label Phase 1, First in Human trial designed to evaluate the safety, tolerability pharmacokinetics, preliminary efficacy of BA1106 in participants with advanced solid tumors.
Detailed Description
BA1106 is a human anti-CD25 monoclonal antibody. There are two parts in the study. Part A is dose escalation study, and Part B is dose expansion study. Part A will be conducted using BOIN dose escalation method at the dosing regimen of once every 3 weeks. In Part B, 1\~2 dose levels, dosing regimens (i.e. once every 2 weeks or once every 3 weeks), and 1\~4 selected indications will be chosen to further evaluate the safety and efficacy of BA1106.

Arms & Interventions
BA1106
Part A (Dose-Escalation): Mixed solid tumors participants will receive ascending doses of BA1106. BA1106 will be administered by intravenous (IV) infusion. The observation period of Dose Limiting toxicity (DLT) is 28 days, then the participants will receive BA1106 every three weeks (Q3W) until confirmed progression, death, unaccepted toxicity, initiation of other antitumor therapies, or any other conditions requiring treatment discontinuation, and the maximum duration of administration was no more than 2 years. Part B (Dose-Expansion): Participants of selected tumors will receive a fixed dose of BA1106 that selected according to the results of Part A once every 3 weeks (Q3W) or once every 2 weeks (Q2W), until confirmed progression, death, unaccepted toxicity, initiation of other antitumor therapies, or any other conditions requiring treatment discontinuation, and the maximum duration of administration was no more than 2 years.
Intervention: BA1106
