What is this trial about?

A plain-language summary of the goals, design and what participants do

This study aims to evaluate the effectiveness and safety of a medication called Eloralintide, which is also known by the code LY3841136. The research focuses on individuals living with Obesity, a condition where excess body fat may affect health, or those who are Overweight but do not have Type 2 Diabetes, a chronic condition that affects how the body processes blood sugar.

Participants in the study will receive either the study drug or a placebo through a subcutaneous injection, which means the medicine is delivered by a needle into the fatty layer of tissue just under the skin. The medication is provided as a solution for injection in a pre-filled syringe and is intended to be used once every week. This research is designed to determine if Eloralintide can lead to a greater reduction in body weight compared to the placebo over a period of time.

The research process

The trial runs in 3 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Participation in the study

    The study begins with the administration of either eloralintide or a placebo, which is an inactive substance used for comparison.

    The medication, eloralintide, is provided as a solution for injection in a pre-filled syringe and is administered through subcutaneous use, which means it is injected into the fatty tissue just under the skin.

  2. Step 2

    Weekly administration

    The assigned medication is administered once weekly.

  3. Step 3

    Weight monitoring

    The percent change in body weight is measured from the baseline, which is the initial measurement at the start of the study, through week 64.

Investigated diseases

  • Obesity

    This condition involves an excessive accumulation of body fat that may impair health. It often occurs when there is an imbalance between the energy consumed through food and the energy used by the body. Over time, the amount of stored fat continues to increase. This process is driven by various factors including diet and physical activity levels.

  • Overweight
