Details and patient eligibility


It is a phase I/II open label, multicenter study to assess the safety, tolerability, pharmacokinetics, and efficacy of HB0028 in patients with advanced solid tumors.

Full description

This is a phase I/II, multicenter, open-label, first-in-human study in patients with advanced solid tumors. During the phase I study, the safety and tolerability of HB0028 will be evaluated in patients with advanced solid tumors. In the phase II study, the safety and efficacy of HB0028 at the RP2D will be evaluated in cohorts of patients with specific solid tumors.

Exclusion criteria

  • Exclusion Criteria Patients are excluded from the study if any of the following criteria apply:

    1. Have clinically active central nervous system (CNS) metastases. Patients with previously-treated brain or meningeal metastases may participate and be eligible for treatment provided they are stable (>4 weeks) 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.

    2. dose expansion (Cervical cancer group): Hydronephrosis, which could not be relieved by clinical treatment

    3. 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.

    4. History of Grade 3-4 immune-related adverse events (irAEs) or irAEs requiring discontinuation of prior therapies, (except for grade 3 endocrinopathy that is managed with hormone replacement therapy).

    5. Use of systemic corticosteroids in a dose equivalent to >10 mg/day of prednisone or other immunosuppressive agent < 2 weeks prior to screening; the use of topical, intraocular, intraarticular, intranasal, or inhaled corticosteroids and systemic steroids to prevent (e.g., allergy to contrast agents) or treat non-autoimmune condition (e.g., delayed hypersensitivity caused by exposure to allergens) or short course (< 5 days) will be allowed

    6.

    8. Anticancer therapy or radiation < 5 half-lives or 4 weeks (whichever is shorter) prior to study entry; palliative radiotherapy to a single area < 2 weeks prior to study screening is permitted. Measurable lesions cannot be previously irradiated unless they have demonstrated growth after radiation therapy (According to RECIST v1.1).
