AM1476 FOR TREATMENT OF SYSTEMIC SCLEROSIS

AM1476 is an oral, small molecule, selective, high-affinity 5-HT2B receptor antagonist. The anti-fibrotic efficacy of AM1476 has been clearly demonstrated in several preclinical state-of-the-art models of fibrosis, whereby AM1476 halted and reversed the progression of pre-established fibrosis in skin and lung tissue.

Phase I study successfully clinically completed – The aim of this double-blind, randomized, placebo-controlled study was to assess the safety and pharmacokinetics of AM1476 in healthy subjects. AM1476 was well tolerated after single and multiple doses and no serious adverse events were reported. After review of study data, including the pharmacokinetics, a dosing regimen of AM1476 in the next clinical study is proposed. The Phase I study will be followed by trials designed to evaluate the treatment effects in patients, initially focusing on systemic sclerosis followed by other fibrotic conditions.

Other Indications

Systemic sclerosis

Systemic sclerosis (SSc) is a severe, rare, chronic autoimmune disease with high morbidity and mortality. About 80 percent of SSc patients are women. The disease process in SSc includes overactivation of the immune system with damage to small blood vessels and increased fibroblast activation resulting in fibrosis of the skin and internal organs, including lungs, heart, kidneys and the gastrointestinal tract.

Other indications

Other indications of high interest for treatment with AM1476 or related compounds include interstitial lung diseases, liver fibrosis, cardiac fibrosis, fibrotic tumors as well as graft-versus-host disease.
