CS1 is a reformulation of valproic acid (VPA), an HDAC (Histone DeACetylase) inhibitor that acts as an epigenetic modulator with anti-thrombotic, anti-inflammatory, anti-fibrotic and pressure-relieving properties. These characteristics are a good match with the mechanisms of the disease involved in PAH.

In December 2019, Cereno Scientific submitted an application for Orphan Drug Designation (ODD) for the development of CS1 in PAH with the U.S. Food and Drug Administration (FDA) and today, the Company received the FDA approval.

"We are very pleased that the FDA has granted orphan drug designation to our HDAC inhibitor CS1, which allows us to implement a clinical development program on the rare and serious disease PAH aiming to help a broader group of patients, that now includes patients with rare diseases, with our lead compound CS1. Our focus to develop drug candidates that effects epigenetic modulation, stems from our commitment at Cereno Scientific to help patients with cardiovascular related diseases." said Sten R. Sörensen, Chief Executive Officer of Cereno Scientific.

The FDA, through its Office of Orphan Products Development (OOPD), grants ODD to drugs and biologic products that are intended for treatment of rare diseases or disorders that affect fewer than 200,000 people in the United States. The ODD status is intended to facilitate drug development for rare diseases and may provide certain benefits and incentives to drug developers, including seven years of market exclusivity if the drug is approved, FDA assistance in clinical trial design, and tax credits for qualified clinical trial costs.
