• Rare Pediatric Disease Designation granted for the treatment of patients with Alström syndrome

• Third Rare Pediatric Disease Designation obtained by Prometic

LAVAL, QC /PRNewswire/ - Prometic Life Sciences Inc. (TSX: PLI) (OTCQX: PFSCF) ("Prometic") today announced that the U.S. Food and Drug Administration (FDA) has granted a Rare Pediatric Disease Designation to its small molecule drug candidate, PBI-4050, for the treatment of Alström syndrome (AS). In addition to the Rare Pediatric Disease Designation, PBI-4050 was previously granted Orphan Drug Designation by the FDA and the EMA for the treatments of AS and idiopathic pulmonary fibrosis (IPF) as well as PIM (Promising Innovative Medicine) designation by the Medicines and Healthcare products Regulatory Agency (MHRA) for the treatment of IPF and AS.

"This is the first pediatric designation granted by the FDA to our small molecule drug candidate PBI-4050 and the third overall, following the previous two granted for our plasma-derived therapeutics candidates. This highlights the depth and value of our two drug discovery platforms," said Mr. Pierre Laurin, President and Chief Executive Officer of Prometic. "We look forward to discussing the potential regulatory approval pathway to bring this innovative therapy to pediatric patients with Alström syndrome during our upcoming meeting with the FDA."

The FDA grants Rare Pediatric Disease Designations for serious or life-threatening diseases wherein the serious or life-threatening manifestations primarily affect individuals aged from birth to 18 years, including age groups often called neonates, infants, children, and adolescents. If and when approved, Prometic's PBI-4050 could be eligible to receive a rare pediatric disease priority review voucher.

More about Alström syndrome:

Alström syndrome is a rare inherited autosomal recessive syndrome characterized by the onset of obesity in childhood or adolescence, Type 2 diabetes, often with severe insulin resistance, dyslipidemia, hypertension and severe multi-organ fibrosis involving the liver, kidney and heart.  Alström syndrome is also characterized by a progressive loss of vision and hearing, a form of heart disease that weakens the heart muscle (dilated cardiomyopathy), and short stature. This disorder can also cause serious or life-threatening medical problems involving the liver, kidneys, bladder, and lungs. The clinical manifestations of Alström syndrome vary in severity, and not all affected individuals have all of the features associated with the disorder.

More about PBI-4050

PBI-4050 is an orally active lead drug candidate with excellent safety and efficacy profiles demonstrated in a large number of animal models of fibrosis affecting different organs, including the lung, liver, heart, kidney, and pancreas. The effects of PBI-4050 demonstrated in animal models have been replicated in Phase 2 studies in idiopathic pulmonary fibrosis (IPF), in metabolic syndrome with type 2 diabetes and in Alström syndrome. PBI-4050 is entering pivotal placebo-controlled Phase 3 clinical trials for the treatment of IPF and has already begun placebo-controlled Phase 2 trials in metabolic syndrome and type 2 diabetes patients.
