dersimelagon (MT-7117) / Mitsubishi Tanabe - LARVOL DELTA

Polymorphism of Melanocortin Receptor Genes-Association with Inflammatory Traits and Diseases. (PubMed, Diseases) - "Among them, α-MSH analogs play a role in atopic dermatitis and scleroderma, and MC1R agonist Dersimelagon has shown effectiveness in systemic sclerosis. The FDA has recently approved the repository corticotropin injection (RCI) to treat sarcoidosis. The FDA has also approved various melanocortin agonists, i.e., Bremelanotide, Afamelanotide, and Setmelanotide, for the treatment of hypoactive sexual desire disorder, Erythropoietic protoporphyria, and obesity, due to pro-opiomelanocortin and leptin receptor deficiency, respectively. Therefore, this review aims to summarize the function and genetic polymorphism of melanocortin receptors, regulatory pathways involving MCRs, and the existing evidence of the prime effect of MCRs on inflammatory responses via different mechanisms and their potential therapeutic use in inflammatory diseases."

Assessment of Potential Drug-Drug Interactions for Novel Oral Melanocortin-1 Receptor Agonist Dersimelagon. (PubMed, Pharmacol Res Perspect) - P1, P2, P3 | "The impact of 300-mg dersimelagon on the pharmacokinetics (PK) of substrate drugs and the effect of co-administering verapamil on 100-mg dersimelagon PK (as substrate drug) were investigated in healthy participants in a Phase 1 study...Midazolam (CYP3A substrate), digoxin (P-gp), pravastatin (OATP), and simvastatin (CYP3A) did not show any clinically relevant DDI effects when co-administered with dersimelagon...Dersimelagon 300 mg did not elicit major DDIs involving CYP/UGT enzymes and drug transporters; however, dersimelagon may have potential for clinically relevant DDIs with drugs that are substrates for BCRP, such as atorvastatin and rosuvastatin, and caution should be exercised when co-administering 300-mg dersimelagon with these statin drugs.

Discovery of MT-7117 (Dersimelagon Phosphoric Acid): A Novel, Potent, Selective, and Nonpeptidic Orally Available Melanocortin 1 Receptor Agonist. (PubMed, J Med Chem) - "Afamelanotide, an α-melanocyte-stimulating hormone (α-MSH) analogue MC1R agonist, is used clinically for treating erythropoietic protoporphyria (EPP) as a subcutaneous implant formulation. Compound 11 is currently in clinical trials for the treatment of EPP, X-linked protoporphyria (XLP), and systemic sclerosis (SSc). Proof of concept was obtained in phase 2 clinical studies on EPP and XLP."

Physiologically based pharmacokinetic modelling to predict potential drug-drug interactions of dersimelagon (MT-7117). (PubMed, Br J Clin Pharmacol) - "Overall, PBPK modelling results indicate that the simulated changes in plasma exposure of atorvastatin and rosuvastatin following coadministration with dersimelagon 100 or 200 mg are not clinically significant, but caution and appropriate clinical monitoring should be recommended."

Topline results of the AURORA Trial: A phase 2, randomized, double-blind, placebo-controlled trial of bitopertin in erythropoietic protoporphyria (EADV 2024) - P2 | "Exclusion criteria included concurrent treatment with afamelanotide or dersimelagon. Bitopertin has been shown to significantly reduce PPIX levels in prior clinical and nonclinical studies of EPP. The AURORA trial evaluates whether reductions in PPIX with bitopertin can improve measures of light tolerance in adults with EPP. Topline safety and efficacy data will be presented."

Effect of Hepatic and Renal Impairment on the Pharmacokinetics of Dersimelagon (MT-7117), an Oral Melanocortin-1 Receptor Agonist. (PubMed, Clin Pharmacol Drug Dev) - P1 | "Maximum observed plasma concentration and area under the plasma concentration-time curve from time 0 extrapolated to infinity were similar with moderate renal impairment but higher with mild (1.86- and 1.87-fold higher, respectively) and severe (1.17- and 1.45-fold higher, respectively) renal impairment versus normal renal function. Dersimelagon was generally well tolerated."

Current trials in erythropoietic protoporphyria: are placebo controls ethical? (PubMed, Orphanet J Rare Dis) - "However, given the availability of an already approved treatment option for EPP the use of a placebo arm is questionable from an ethics point of view. We analyze the issue and suggest that a noninferiority active-control trial without placebo is an ethically and scientifically more valid design to test the efficacy of dersimelagon as well as other EPP treatments."
