Trial Summary

Will I have to stop taking my current medications?

The trial requires stopping certain medications before participating. You must not use phototherapy, afamelanotide, cimetidine, or certain antioxidant agents within 3 to 4 weeks before starting. Additionally, you should avoid drugs metabolized by specific enzymes or proteins within 1 week before starting.

What data supports the effectiveness of the drug Dersimelagon for treating Erythropoietic Protoporphyria?

Dersimelagon is being developed as a new oral drug for Erythropoietic Protoporphyria, and studies show it increases skin eumelanin, which may help reduce sensitivity to light. It is rapidly absorbed and eliminated from the body, supporting its potential as a treatment for photosensitive conditions.12345

How is the drug dersimelagon different from other treatments for erythropoietic protoporphyria?

Dersimelagon is unique because it is an oral drug that works by selectively activating the melanocortin 1 receptor, which increases skin eumelanin levels, potentially reducing sensitivity to light. This mechanism is different from other treatments, and its oral administration makes it more convenient compared to other options.12345

What is the purpose of this trial?

This trial is testing a pill called dersimelagon to see if it is safe and tolerable for patients who need long-term treatment.

Findings from Research

Dersimelagon, a new oral medication for conditions like erythropoietic protoporphyria, showed rapid absorption and a 97% relative oral bioavailability for the 100-mg tablets compared to the 50-mg tablets in a study involving 50 healthy participants.
The study found that while a high-fat meal did not affect the overall exposure of dersimelagon, it increased the peak concentration (Cmax) by 22%, indicating that food intake can influence the drug's absorption.
The Oral Bioavailability and Effect of Various Gastric Conditions on the Pharmacokinetics of Dersimelagon in Healthy Adult Volunteers.Ogawa, K., Ide, R., Belongie, K., et al.[2023]
Dersimelagon is a novel oral medication that shows rapid absorption and elimination in humans, with a median time to peak concentration of 2 hours, indicating efficient processing by the body.
The drug is primarily excreted through feces rather than urine, with negligible retention in the body, suggesting a favorable safety profile for continued development in treating conditions like erythropoietic protoporphyria and systemic sclerosis.
Absorption, metabolism, and excretion of [14 C]dersimelagon, an investigational oral selective melanocortin 1 receptor agonist, in preclinical species and healthy volunteers.Tsuda, M., Ogawa, K., Endou, T., et al.[2023]
Dersimelagon, an investigational oral medication for erythropoietic protoporphyria (EPP) and X-linked protoporphyria (XLP), was found to be generally well tolerated in a phase 1 study involving healthy participants, with common side effects including skin hyperpigmentation.
The pharmacokinetics of dersimelagon showed a consistent profile across different age and race groups, with significant increases in melanin density observed after multiple doses, suggesting potential efficacy that needs further exploration in larger studies.
