Eloralintide
Eloralintide (LY3841136) is a novel, long-acting, selective amylin receptor agonist developed by Eli Lilly for the treatment of obesity. Research shows it mimics the natural hormone amylin to reduce appetite, decrease food intake, and promote significant weight loss, primarily through fat mass reduction.

02Mechanism of action
Amylin Receptor Activation
Eloralintide selectively binds to and activates the amylin receptors (AMY1R), mimicking the action of the native hormone amylin, which is co-secreted with insulin.
Satiety Modulation
Activation of these receptors in the brain increases feelings of fullness (satiety) and delays gastric emptying, leading to a reduction in caloric intake.
Weight and Fat Reduction
The sustained decrease in food intake results in significant body weight loss, with studies indicating that the weight lost is predominantly fat mass.
03Human evidence
In a Phase 2 trial, eloralintide produced clinically meaningful, dose-dependent reductions in body weight over 48 weeks, with up to 20% weight loss at the 9 mg dose.
Phase 2 clinical trial involving adults with obesity or overweight, comparing various doses (1 mg to 9 mg) of eloralintide to placebo.
Eloralintide lowered resting heart rate, an effect consistent with other non-selective amylin receptor agonists.
Observed in clinical studies evaluating the safety and tolerability of the compound.
04Preclinical evidence
Eloralintide selectively activates human AMY1R compared to human AMY3R and CTR, inducing weight loss mainly through fat mass reduction.
Rodent models used to evaluate receptor selectivity and body composition changes.
The compound induced decreased appetite, reduced food intake, and prolonged plasma calcium reduction.
Preclinical animal studies assessing the physiological effects of amylin receptor agonism.
05What is known vs. unknown
- Eloralintide is a selective amylin receptor agonist designed for once-weekly subcutaneous injection.
- It has demonstrated up to 20% body weight reduction in Phase 2 clinical trials over 48 weeks.
- The weight loss achieved is primarily due to a reduction in fat mass rather than lean muscle.
- It works by modulating satiety and delaying gastric emptying, similar to the native hormone amylin.
- Long-term safety and efficacy beyond 48 weeks are still being evaluated in ongoing Phase 3 trials.
- The exact cardiovascular outcomes and potential long-term effects on resting heart rate require further investigation.
- Optimal combination strategies with other weight-loss medications (like GLP-1 agonists) are still under study.

AOD-9604
AOD-9604 is a modified fragment of human growth hormone (HGH) that includes amino acids 177-191. Research indicates it mimics the fat-burning effects of HGH by stimulating lipolysis and inhibiting lipogenesis, without the adverse effects on blood sugar or tissue growth typically associated with full-length HGH.
MOTS-c
MOTS-c is a naturally occurring mitochondrial-derived peptide that plays a key role in regulating metabolic homeostasis and energy production. Research indicates it acts as an 'exercise mimetic' by activating AMPK, improving insulin sensitivity, and enhancing physical performance in animal models.
GLP3-RT (Retatrutide)
Retatrutide is an investigational triple hormone receptor agonist that targets GLP-1, GIP, and glucagon receptors. Clinical trials have shown unprecedented weight loss efficacy, surpassing dual agonists, by combining appetite suppression with increased energy expenditure.
