An Engineered Sirpα Fused to Anti-Pd-L1 And Tgf-β Fusion Protein (HCB301) in Subjects With Selected Advanced Tumors

Recruiting now · Phase 1

Conditions studied: Advanced Solid Tumor, Refractory Hodgkin Lymphoma

In brief

The purpose of this study is to find out whether IV injection of HCB301 is an effective treatment for different types of advanced solid tumors and relapsed and refractory classical Hodgkin lymphomas and what side effects (unwanted effects) may occur in subjects aged 18 years old and above.

Histologically/cytologically confirmed, locally advanced solid tumor:
subjects confirmed advanced solid tumors who have relapsed or refractory and should have no options for standard or approved therapies known to potentially confer clinical benefit or classical Hodgkin lymphoma, relapsed or refractory to at least 2 prior lines of systemic therapy.
For subjects with advanced solid tumors - must have at least 1 measurable lesion as defined by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 at baseline.
For subjects with classical Hodgkin lymphoma - must have classical Hodgkin lymphoma that is measurable or assessable for response.
Must have ECOG performance status of 0 to 1 at Screening.
Able to provide tumor tissue samples.
Have a life expectancy of ≥12 weeks.

You may not qualify if…

With known history of hypersensitivity to any components of HCB301.
Known active or untreated CNS metastases and/or carcinomatous meningitis.
Have undergone a major surgery or radical radiotherapy within 28 days or palliative radiotherapy within 14 days or have used a radioactive drug within 56 days prior to the first dose of HCB301.
