a study of bh009 in head and neck squamous cell carcinoma and ovarian cancer

Conditions: Solid Tumor, Adult

Summary: this study will assess the safety and tolerability and pharmacokinetics of bh009 in patients with advanced head and neck squamous (non-nasopharyngeal) and ovarian cancer.

this is a multicenter, open label phase i clinical study to evaluate the safety, tolerability, and pharmacokinetic profile of bh009 in patients with advanced squamous head and neck cancer (non-nasopharyngeal) and ovarian cancer, and to initially explore its clinical effectiveness. this study will use a "3+3" dose escalation design to determine the maximum tolerated dose (mtd) and the recommended phase 2 dose (rp2d) of bh009.

with the exception of the following: treatment with topical, ophthalmic, intra-articular, intranasal, and inhaled glucocorticosteroids; and short-term prophylactic glucocorticosteroids (e.g., prevention of allergy to contrast media). 5. subjects with clinically significant psychiatric or central nervous system disorders. 6. subjects with a primary malignant tumour of the brain; or those who with two or more malignant tumours (except cured non-melanoma skin cancer, cervical cancer, thyroid cancer and intramucosal cancer of the gastrointestinal tract). 7. subjects who with serious medical conditions: * subjects with clinically significant cardiovascular disease, including: severe or uncontrolled heart disease requiring treatment, congestive heart failure classified by the new york heart association (nyha) as grade 3 or 4, unstable angina pectoris uncontrolled by medication, history of myocardial infarction within 6 months prior to enrolment, severe arrhythmia requiring medication (except atrial fibrillation or paroxysmal supraventricular tachycardia); * subjects with indwelling cardiac stents within 6 months; * subjects with uncontrolled hypertension (systolic blood pressure ≥160 mmhg and/or diastolic blood pressure ≥100 mmhg after pharmacological intervention), diabetes mellitus (glycated haemoglobin hba1c ≥8.0% or fasting blood glucose ≥10.0 mmol/l), pleural effusion, pericardial effusion, ascites;
