Brief Summary:
This is a phase I, randomized, double-blinded, placebo-controlled, single and multiple dose escalation study to evaluate the safety, tolerability, pharmacokinetic characteristics and pharmacodynamics of HX15001 in adult healthy participants.
The study consists of two parts: Part A involves single-dose escalation (Cohorts 1-7), and Part B involves multiple-dose escalation (Cohorts 8-9).
The primary objective of this study is to characterize the safety and tolerability of single and multiple doses of HX15001 in healthy subjects.

Detailed Description:
This study consists of two parts. Part A: This part includes seven sequential ascending-dose cohorts, designated as Cohorts 1 through 7. Cohort 1 and Cohort 6 will enroll four healthy subjects in each cohort. Cohort 2 will enroll six healthy subjects. The remaining four cohorts will enroll eight healthy subjects each.
On Day 1, after final eligibility has been determined, subjects in Cohorts 1-5 will be randomly assigned to receive a single subcutaneous dose (which may be split into multiple dosing syringes) of HX15001 or placebo, while subjects in Cohorts 6 and 7 will be randomly assigned to receive a single intravenous infusion of HX15001 or placebo. The doses for Cohorts 1-7 will be administered as per the protocol.
Part B: This part consists of two multiple-dose cohorts (Cohorts 8 and 9), each enrolling eight healthy subjects. Subjects in these cohorts will receive subcutaneous doses of HX15001 or placebo on Days 1, 15, and 43. Dosing will be followed by safety, pharmacokinetic, pharmacodynamic, and immunogenicity assessments.
Study Period Part A: Screening：Up to 28 days Treatment：Day 1 single dose Follow up: 112 days including Day 1 (Cohort 1-3) 140 days including Day 1 (Cohort 4-7) Part B: Screening：Up to 28 days Treatment：Day 1, Day 15, Day 43 (single dose on each visit) Follow up: 20 weeks (Day 183) The final follow-up visit will be determined based on the safety and PK data derived from the previous SAD and MAD cohorts, which may be earlier or later than Day 183 (±7 days
