Phase 1

Completed

• Conditions: Acute Ischemic Stroke
• Interventions: Drug: QHRD106 Injection; Drug: placebo

• Registration Number: NCT06388772
• Lead Sponsor: Changzhou Qianhong Bio-pharma Co., Ltd.

Brief Summary

The purpose of this study is to assess the safety, tolerability and pharmacokinetics (PK) of QHRD106 early in Chinese healthy subjects with single doses.

Detailed Description

Eight dose groups were initially set up. The experimental groups were increased from low to high dose according to the principle of increasing dose, and Placebo was added as the control group. All the selected subjects in the experimental group were given the drug once.
