Study Overview

• Status: Recruiting
• Conditions: Hiv
• Intervention / Treatment: Drug: LP-98 injection

Detailed Description

The study was divided into two parts, Part A and Part B. The Part A and Part B studies were carried out separately according to the protocol flow, with the Part A study carried out first.

1. Part A is set up with 5 cohorts(5mg, 10mg, 20mg, 40mg, 80mg), administration is by subcutaneous, each subject entered only one cohort to receive the drug. 4 subjects were included in cohort 1, and 8 subjects were planned to be included in each cohort 2 to 5, to observe the safety, tolerability, PK and ADA of LP-98 injection by subcutaneous.
2. Part B is set up with 6 cohorts (5mg,10mg,20mg,40mg,80mg, 160mg), administration is by intravenous drip, each subject entered only one cohort to receive the drug. 4 subjects were included in cohort 1, and 8 subjects were planned to be included in each cohort 2 to 6, to observe the safety, tolerability, PK and ADA of LP-98 injection by intravenous drip.
