What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 80 participants in total. It began in 2022-08-25 with a primary completion date of 2025-08-01.

Brief Summary

It is a Phase I/II, Open-label, Multicenter Study to Evaluate the Safety, Pharmacokinetics, Pharmacodynamics, and Efficacy of HB0036 in Subjects with Advanced Solid Tumors

Eligibility Criteria

Inclusion Criteria Patients must meet all the following criteria to be eligible for participation in this study: 1. Male or female. Age ≥ 18 years; 2. Phase I: Patients with histologically or cytologically confirmed locally advanced, recurrent, or metastatic solid tumors (or clinically diagnosed hepatocellular carcinoma) that failed all standard therapies known to provide clinical benefit; \[These solid tumors include but not limit to: non-small cell lung cancer, esophageal squamous cell carcinoma, melanoma, head and neck squamous cell carcinomas, hepatocellular carcinoma, gastric or gastroesophageal junction adenocarcinoma, renal cell carcinoma, etc.\]; 3. Phase II: Histologically or cytologically documented locally advanced, recurrent or metastatic cancer. There will be several tumor-specific cohorts Advanced non-small cell lung cancer cohort Histologically or cytologically documented locally advanced, recurrent or metastatic NSCLC; Confirmed availability of representative tumor specimens in formalin-fixed paraffin-embedded (FFPE）blocks or at least 5 stained serial slides or fresh biopsied specimens (preferred),samples obtained before adjuvant / neoadjuvant chemotherapy are allowed only if biopsy cannot be performed; Tumor PD-L1 expression with a TPS≥1 %; Negative for actionable molecular markers \[including but not limited to: epidermal growth factor receptor (EGFR) mutations, anaplastic lymphoma kinase (ALK) gene fusion mutation, etc.\]； Assessed by the investigator as likely to benefit from the study drug therapy; and should have progressed at least one prior systemic therapy regimen. Advanced other cancer cohort Histologically or cytologically documented locally advanced, recurrent or metastatic cancer (esophageal squamous cell carcinoma, melanoma) Other tumor histologies will be evaluated pending data from the dose escalation phase that may inform on possible efficacy in select tumors 4.

Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0-1 6. Life expectancy ≥12 weeks 7. Adequate organ function within 14 days of the first dose as defined by the following criteria: a) Hematology * absolute neutrophil count (ANC) ≥ 1.5×109/L; ② platelets (PLT) ≥ 75×109/L; ③ hemoglobin (HGB) ≥ 90 g/L; Note: The above three items require that patients should not have received any blood component or cell growth factor supportive therapy within two weeks prior to blood sampling. b) Renal function: Calculated creatinine clearance (CrCL) \> 50 mL/min (Cockroft-Gault Equation); c) Liver function: * AST and ALT ≤ 2.5×ULN; AST or ALT ≤5×ULN if liver metastases are present; ② Total bilirubin (TBIL) ≤ 1.5×ULN; ≤3 X ULN for patients with Gilbert's disease; d) Coagulation function: * International normalized ratio (INR)or prothrombin time (PT)≤ 1.5×ULN (unless patient on oral anticoagulant with stable dose); ② Activated partial thromboplastin time (APTT)≤ 1.5×ULN; 8. Women of childbearing potential must confirm a negative serum or urine pregnancy test within 3 days prior to the initiation of study treatment; Fertile patients and their partners must agree to use effective contraceptives for the duration of study drug use and for 90 days after the last administration of study treatment 9. Recovery to Grade 0-1 from adverse events (AEs) related to prior anticancer therapy except alopecia, \< Grade 2 sensory neuropathy, and endocrinopathies controlled with hormone replacement therapy 10. The subject is able to understand and willing to sign the ICF; willing and able to comply with all study procedures. Exclusion Criteria Patients are excluded from the study if any of the following criteria apply: 1. Concurrent malignancy \< 5 years prior to entry other than adequately treated cervical carcinoma-in-situ, localized squamous cell cancer of the skin, basal cell carcinoma, localized prostate cancer, ductal carcinoma in situ of the breast, or \< T1 urothelial carcinoma. Patients with prostate cancer that is under active surveillance are eligible. 2. Phase I: Patients may have received single agent treatments targeting the TIGIT pathway. Phase II: Have received previous simultaneous therapy with a PD-1 pathway inhibitor and a TIGIT inhibitor; previous monotherapy with TIGIT/PD-1/PD-L1 inhibitor is allowed. 3. Have received antibiotics lasting over 1 week within 28 days prior to first dose; 4. Have clinically active central nervous system (CNS) metastases and/or carcinomatous meningitis. Patients with previously-treated brain or meningeal metastases may participate and be eligible for treatment provided they are stable and asymptomatic. Patients with asymptomatic brain metastasis or subjects who are symptomatically stable after treatment and are on \< 10 mg/d prednisone or equivalent are eligible. 5. Have history of interstitial lung disease or non-infectious pneumonitis (except from radiotherapy); 6. Active autoimmune disease or history of autoimmune disease requiring systemic therapy \< 2 years prior to screening except hypothyroidism, vitiligo, Grave's disease, Hashimoto's disease, or Type I diabetes. Patients with childhood asthma or atopy that has not been active in the 2 years prior to study screening are eligible. 7.

Patients with active tuberculosis (TB) who are receiving anti-TB treatment or who received anti-TB treatment within 1 year prior to screening; 19. Women who are pregnant or lactating, or women of childbearing potential who do not wish to use effective contraception method during the trial. 20.
