SRSD384 Investigated for Safety, PK/PD in Overweight/Obese Individuals, Alone and with Tirzepatide

A Study of SRSD384 in Overweight or Obese Participants

Background

Obesity and Type 2 Diabetes Mellitus (T2DM) are global health crises, often co-occurring and driving significant morbidity and mortality. Current pharmacotherapies, while effective, still leave a substantial unmet need for improved weight loss, glycemic control, and long-term safety profiles. Novel therapeutic agents are continuously sought to enhance metabolic outcomes, either as monotherapy or in combination with established treatments like GLP-1 receptor agonists. This study aims to characterize the initial human profile of SRSD384.

Study Design

This two-part Phase 1/2 study investigated SRSD384 in overweight or obese participants. Part A evaluated the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of a single subcutaneous (SC) dose of SRSD384 as monotherapy. Part B assessed these same parameters for SRSD384 in combination with tirzepatide in overweight or obese participants also diagnosed with Type 2 Diabetes Mellitus. The study aimed to characterize the initial human profile of SRSD384.

Results

The abstract describes the study design and objectives but does not present specific results or findings. Data regarding the safety, tolerability, pharmacokinetics, or pharmacodynamics of SRSD384 as monotherapy or in combination with tirzepatide are not provided in this record. Therefore, no quantitative outcomes, statistical significances, or effect sizes can be reported from this abstract.

Why It Matters

This initial Phase 1/2 study of SRSD384 is crucial for understanding its foundational human profile. If successful, it could pave the way for a novel therapeutic agent for obesity and T2DM, potentially offering a new mechanism or an improved combination strategy with existing GLP-1/GIP agonists like tirzepatide. Characterizing SRSD384's safety and PK/PD is the first step towards developing new protocols for metabolic health. Future research will determine if SRSD384 offers superior efficacy, tolerability, or synergistic benefits when combined with other agents, potentially influencing future treatment stacks for weight management and glycemic control.
