FOP(fibrodysplasia ossificans progressiva) is an extremely debilitating disease manifested through inflammatory-related episodes of heterotopic ossification, that is, bone formation at extra-skeletal sites. Although a number of potential therapies are currently under investigation, unfortunately there is no proven effective treatment yet. FOP is caused by gain-of-function mutations in the ACVR1 gene, resulting in enhanced SMAD1/5 signaling and aberrant differentiation and activation of bone cells. Preliminary results have shown that the PI3Ka inhibitor BYL719 (Alpelisib), currently under investigation for the treatment of several types of cancer, effectively inhibits heterotopic ossification in a preclinical model of FOP by interfering with ACVR1 downstream signaling. Together with Dr. Francesc Ventura (University of Barcelona, Spain) and supported by FOP Stichting Nederland, AEFOP (Spanish association of FOP) and the international FOP association (IFOPA), this project aims to optimize the use BYL719 as a potential therapy for FOP, and investigate the mechanisms by which BYL719 may normalize ACVR1 signaling in animal models of FOP and patient-derived iPSCs. This information is absolutely required to implement this potential therapy for treatment of FOP patients and other forms of heterotopic ossification.
