Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Phase I:

Primary Research Objective:

Evaluate the safety, tolerability, and pharmacokinetic characteristics of a single dose of DGPR1008 in healthy subjects.

Secondary Research Objective:

Based on the safety and pharmacokinetic results, assess the maximum tolerated dose (MTD) and the recommended phase II dose (RP2D) of DGPR1008.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

0.01mg/kg DGPR1008 Injection Dose Group 1 (n=6)

On the day of administration, subjects will be randomized to receive the DGPR1008 Injection (0.01 mg/kg; n=6) via slow IV infusion over 60-90 minutes.

Infusion Monitoring: Closely assess for infusion reactions; discontinue if necessary.

Post-Infusion: Inspect injection site for erythema, pruritus, etc. Protocol Adherence: Conduct bio-sample collection, safety checks, and document all adverse events/concomitant therapies.

Group Type EXPERIMENTAL

0.01mg/kg DGPR1008 Injection Dose Group 1 (n=6)
