The goal of this intervention study is to evaluate the Safety, Tolerability and Pharmacokinetic Characteristics of HXN5003 in Healthy Participants.The main parameters it aims to answer are:
1. Does a single dose of HXN5003 in healthy participants impact the safety, tolerability and pharmacokinetic profiles?
2. Will immunogenicity of HXN5003 in healthy participants be altered? This study will be compared against a Placebo which contains the same inactive ingredients as those of HXN5003, but without the active ingredient.

The goal of this clinical trial is to evaluate the safety, tolerability, pharmacokinetic characteristics and pharmacodynamics of HXN6005 in Healthy Participants.
Researchers will compare HXN6005 to a placebo (a look-alike substance that contains no drug).
Participants will take a single dose of HXN6005 or placebo on Day 1, and visit the clinic for followup and tests per the protocol scheme.

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.
