About

The objectives of this study are to evaluate the safety, tolerability, and pharmacokinetic profile of HB002.1T in combination with different chemotherapy regimens administered to patients with advanced solid tumors.

Full description

This study is a Phase1b, multicenter, open-label, dose-escalation and dose-expansion in selected solid tumor indications. There are two parts to this study: a dose-escalation part and a dose-expansion part. About 63-72 subjects is planned to recruit, 27~36 subjects (9~12 subjects each arm) will be recruited during dose-escalation period The sample size may vary depending on the DLT observed at each dose level. The conventional 3+3 design will be applied for dose escalation. This trial will evaluate two adaptive dose levels, 3 to 6 subjects will be enrolled at each dose level depending on the occurrence of dose limiting toxicities (DLTs). Cohorts of 3 subjects with metastatic or locally advanced solid tumors will receive HB002.1T at escalating dose levels in combination with different chemotherapy regimens. After determination of the Maximum tolerated dose (MTD), another 12 patients in each of 3 cohorts will be added to determine the safety, tolerability, pharmacokinetic (PK), and clinical activity of HB002.1T.

Enrollment: 72 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers
