Study Description
Brief Summary
To select RP2D/MTD of HBM4003 in combination with Toripalimab in dose confirmation part(Part
- and use the RP2D in dose expansion part (Part 2) to evaluate the safety, tolerability, PK/PD and preliminary efficacy of in patients with advanced NEN and other solid tumors
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
| Phase 1 |
Detailed Description
Subjects will be treated with HBM4003 in combination with Toripalimab for up to 2 years or until confirmed disease progression, unacceptable tolerability or treatment discontinuation through withdrawal of consent occurs, whichever happens first.
This trial consists of:
-
A screening period: 28 days
-
A treatment period: no longer than 2 years (Part 1 dose escalation study or Part 2 dose expansion)
-
A post-treatment follow-up period, including 28 days and 84 days after the last dose of study drug;
-
Survival follow-up.
