Brief Summary
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.

Eligibility Criteria
You may qualify if:
- Able to understand and be willing to sign the ICF.
- Male and female subjects of ≥18 years of age.
- 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.
- Clinically significant cardiovascular condition.
- Any previous treatment-related toxicities which have not recovered to ≤ Grade 1 as evaluated by National Cancer Institute, Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0 or baseline, except alopecia and anemia.
- With known inherited or acquired bleeding disorder or bleeding diathesis. .
- Have RBC transfusion within 4 weeks prior to Screening.
- With a previously documented diagnosis of hemolytic anemia or Evans Syndrome in the last 3 months.
- Any investigational or approved systemic cancer therapy administered within 21 days or 5 half-lives, whichever is shorter, before the first dose of the study drug.
- Active use of vitamin K antagonist anticoagulant like warfarin. Use of low molecular weight heparin and factor Xa inhibitors will be permitted on case by case basis. There will be no restriction for daily aspirin ≤ 100 mg/QD.
- Have used herbal medication within 14 days prior to the first dose of HCB301.
- Have received any treatment targeting the SIRPα-CD47, PD-L1, or TGF-β pathway.
- Have other malignancies requiring treatment within 2 years prior to the first dose of HCB301.
- An investigational device used within 28 days prior to the first dose of HCB301.
- Positive for hepatitis B, active hepatitis C infections, positive for HIV, or known active or latent tuberculosis.
