Study Summary

This trial aims to test the safety, side effects, and how the body processes RM-718 in both healthy individuals with obesity and patients with a specific type of obesity called hypothalamic obesity.

Who is the study for?
This trial is for adults aged 18-55 with obesity (BMI ≥30 kg/m2) and patients aged 12-65 with hypothalamic obesity due to brain lesions or injury. Participants must be in good health, able to follow the study's requirements, use effective contraception, and provide informed consent.Check my eligibility
What is being tested?
The study tests RM-718's safety, tolerability, and pharmacokinetics (PK). It has three parts: A & B involve comparing RM-718 with a placebo in healthy obese subjects; Part C administers RM-718 to patients with hypothalamic obesity.See study design
What are the potential side effects?
While specific side effects of RM-718 are not listed here, common side effects from new medications may include nausea, headaches, allergic reactions or skin irritation at the injection site if applicable.

Why did patients apply to this trial?

Since my craniophargioma I have a constant battle with gaining weight, I have tried the glp-1 injections that were not effective and made me feel awful and was looking for something to help.

I have had HO since I had surgery the first time for a craniophyrangioma. It’s so frustrating!! It’s also career limiting. I’m an adult- I can’t imagine what it’s like for children. I’m thankful that teams are working on some options for this silent diagnosis.
