A Study of Injection HB0025 in Patients With Advanced Solid Tumors

Status unconfirmed · Phase 1

Conditions studied: Tumor, Subjects

In brief

This is a multicenter, open-label, dose escalation and expansion study. During the study, subjects will be evaluated for safety, toxicity, tolerability, PK/PD, immunogenicity, biomarkers, and antitumor activity of HB0025. The phase I study will enroll up to 154 subjects with advanced solid tumors who have progressed on or after standard of care therapy and for whom there is no further treatment available that in the judgement of the patient's physician would be beneficial. One cycle is defined as 28 days.

• b) Advanced Renal Cell Carcinoma Cohort and Advanced Endometrial Carcinoma Cohort:
• i) Histopathological and/or cytological diagnosis of patients with advanced clear cell renal carcinoma, advanced endometrial carcinoma, who are not suitable for radical treatment or have relapsed/metastatic disease; Advanced clear cell renal carcinoma should be assessed as medium-high risk by the International Metastatic Renal Cell Carcinoma Database Alliance (IMDC).

• Absolute neutrophil count ≥1,500/µL without growth factor support within 2 weeks prior to the first dose of HB0025.
• Hemoglobin ≥ 9 g/dL without transfusion or erythropoietin within 2 weeks prior to the first dose of HB0025.
• Platelet count ≥ 75,000/µL without transfusion or recombinant human thrombopoietin within 2 weeks prior to the first dose of HB0025.
• Coagulation: International Normalized Ratio (INR)≤1.6 (unless receiving anticoagulation therapy). Subjects on full-dose oral anticoagulation must be on a stable dose (minimum duration 14 days). If receiving warfarin, the subject must have an INR≤3.0 and no active bleeding (ie, no bleeding within 14 days prior to first dose of study drug). Subjects on low molecular weight heparin will be allowed. Subjects must have no active bleeding or clinically significant bleeding within 14 days prior to first dose of study drug.

You may not qualify if…

• Patients who meet any of the following criteria cannot be enrolled:
