Obesity / Overweight
Conditions
Brief summary
This is a placebo-controlled, double-blind trial to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of single and multiple ascending doses of TQF6422 Injection in overweight or obese healthy participants.
Interventions
TQF6422 injection is an anti-ActRIIA/IIB monoclonal antibody.
A placebo matching TQF6422 Injection in appearance, dosage form, and route of administration, but containing no active ingredient.

Eligibility
Inclusion criteria
1. Chinese male or female trial participants aged ≥18 years (inclusive) and ≤55 years (inclusive). 2. Participant body weight ≥50 kg, with body-mass index (BMI) of 24-40 kg/m² (end-points included). 3. At screening, the following findings shall be within normal limits, or deemed clinically insignificant by the Investigator despite being abnormal and not meeting
Exclusion criteria
vital signs, physical examination, 12-lead electrocardiogram (ECG), chest X-ray, abdominal ultrasound, and clinical laboratory tests (including but not limited to hematology, urinalysis, serum biochemistry, coagulation function, serological virology, and thyroid function). 4. Negative human immunodeficiency virus antibody (HIV-Ab) test. 5. For female participants: 1. Non-childbearing potential: including surgical sterilization performed at least 6 weeks prior to screening visit (documented tubal ligation, hysterectomy, or bilateral oophorectomy), or post-menopausal status for ≥12 months prior to screening visit (confirmed by follicle-stimulating hormone (FSH) level ≥40 IU/L); OR 2. Child-bearing potential: must be non-pregnant and non-lactating, and must agree to use effective (at least one highly-effective) non-pharmacological contraceptive measures from 14 days before screening, throughout the study period, and for 6 months after study drug administration. Serum pregnancy test shall be negative with human chorionic gonadotropin (hCG) \<5 mIU/mL at screening and baseline (D-1). Participants shall not donate ova during this period. 6. Male participants with female partners of child-bearing potential must agree to use effective (at least one highly-effective) non-pharmacological contraceptive measures from 14 days before screening, throughout the study period, and for 6 months after study drug administration. Male participants shall not donate sperm during this period. 7. Voluntarily provide written informed consent prior to trial participation, with full understanding of trial content, procedures and potential adverse reactions; able to communicate adequately with the Investigator, and understand and comply with all study-related requirements.
