What this trial studies

This study aims to assess the tolerance and side effects of LY4057996 in both healthy participants and those diagnosed with Type 1 and Type 2 Diabetes. Participants will receive the study drug either subcutaneously or intravenously, and blood tests will be conducted to measure the drug's absorption and elimination from the body. The study is structured into multiple parts, lasting between 4 to 11 weeks, depending on the participant group. The goal is to gather comprehensive data on the drug's safety profile and pharmacokinetics.

Who should consider this trial

Good fit: Ideal candidates include healthy individuals and those with Type 1 or Type 2 Diabetes meeting specific criteria regarding their diabetes management and health status.

Not a fit: Patients with uncontrolled diabetes or those not meeting the specific inclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options for individuals with Type 1 and Type 2 Diabetes.

How similar studies have performed: Other studies have shown promise in evaluating similar interventions, but the specific approach of LY4057996 is novel.
