Eligibility Criteria
Inclusion Criteria:
Previously received the following lines of systemic therapy for the advanced/metastatic disease:
- Gastric cancer: at least 2 lines of therapy
- Renal cell carcinoma: at least 2 lines of therapy
Melanoma:
- BRAF V600E mutant: must have received at least 2 lines of therapy
- BRAF V600E wild type: must have received at least 1 line of therapy
- Sarcoma: at least 1 line of therapy
- Testicular germ cell tumor: at least 2 lines of therapy
- Cervical cancer: at least 2 lines of therapy
- Mesothelioma: at least 2 lines of therapy
- Non-small cell lung cancer: at least 2 lines of therapy
- Head and neck squamous cell carcinoma: at least 2 lines of therapy
- Suitable site to biopsy at pre-treatment and on-treatment
- Measurable disease as determined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 or modified RECIST (mRECIST) for mesothelioma
- Eastern Cooperative Oncology Group performance status of 0 or 1
Exclusion Criteria:
- Systemic anti-cancer therapy within 2 weeks prior to start of study drug or within 4 weeks for immune-oncologic therapy
- For soft tissue sarcoma and testicular germ cell tumor patients only: prior immune therapy
- Therapeutic radiation therapy within the past 2 weeks
- Prior exposure to agents targeting the Tumor Necrosis Factor Receptor type 2 (TNFR2) receptor
- Active autoimmune disease requiring systemic treatment in the previous 2 years
- Systemic steroid therapy (>10 mg/day of prednisone or equivalent) or any immune suppressive therapy ≤ 14 days before first dose
Persisting toxicity of ≥Grade 2 (≥Grade 1 for diarrhea) relating to prior anti cancer therapy with the following exceptions:
- All grades of alopecia are acceptable
- Endocrine dysfunction on replacement therapy is acceptable
- Severe or unstable medical condition, including uncontrolled diabetes, coagulopathy, or unstable psychiatric condition
- Major surgery within 4 weeks of the first dose of study drug
- History or presence of drug or non-drug induced interstitial lung disease or pneumonitis ≥Grade 2. For combination only: non-small cell lung cancer patients, mesothelioma or patients with significantly impaired pulmonary function or who require supplemental oxygen at baseline must undergo an assessment of pulmonary function at screening
- History of allergic reactions, immune related reactions, or cytokine release syndrome (CRS) attributed to compounds of similar chemical or biologic composition to monoclonal antibodies or any excipient of HFB200301
- Using sensitive substrates of major cytochrome P450 (CYP450) enzymes
- Known active malignancy, with the exception of the specific cancer under investigation in this trial, that required treatment within the previous 2 years
- For combination only: Prior randomization in a tislelizumab study regardless of the treatment arm, until the primary and key secondary endpoints of the study have read out

Dose Escalation - HFB200301 monotherapy
Dose Escalation - HFB200301 in combination with tislelizumab
Dose Expansion - HFB200301 monotherapy
Dose Expansion - HFB200301 in combination with tislelizumab
Participants will be administered HFB200301 at dose levels 1-5 as an intravenous infusion to determine the Recommended Dose for Expansion (RDE).
Participants will be administered HFB200301 at dose levels 1-4 in combination with one dose level of tislelizumab as an intravenous infusion to determine the combination Recommended Dose for Expansion (RDE).
Participants will be administered HFB200301 at monotherapy RDE as an intravenous infusion.
Participations will be administered HFB200301 in combination with tislelizumab at combination RDE as an intravenous infusion.
