FDA Granted Orphan Drug Designation to CER-001 for the Treatment of LCAT Deficiency
ABIONYX Pharma (FR0012616852 – ABNX – PEA PME eligible), a new generation biotech company dedicated to the discovery and development of innovative therapies for patients, today announced that the U.S. Food and Drug Administration (FDA) has granted orphan-drug designation (ODD) to the Bio-HDL CER-001 for the treatment of lecithin-cholesterol acyltransferase (LCAT) deficiency. The designation covers both partial LCAT deficiency, presenting as Fisheye Disease, and complete LCAT deficiency presenting with renal symptoms and corneal opacities. Progression of LCAT deficiency, for which there is no approved treatment, can ultimately lead to renal failure requiring dialysis or kidney transplant, and/or to complete corneal opacification requiring transplant.
The European Medicines Administration (EMA) granted ODD status to CER-001 for the treatment of LCATdeficiency in July 2021. Positive clinical results from CER-001 in LCAT disease have previously been published. In the Annals of Internal Medicine in March 2021, a case study of a patient who was about to undergo dialysis due to the rapid decline in renal function was described. The patient was able to avoid the need for dialysis during her treatment with CER-001 and in addition, lipid deposits in her corneas which had caused signficant visual blurring, improved with treatment. The improvement in visual function was still observed after 1 year of follow-up. A second case was described in the Journal of Internal Medicine in November 2021 and showed that CER-001 reduced glomerular lipid deposits and slowed the patient’s decline in renal function. Furthermore, CER-001 remodeled his plasma lipoproteins by reducing the level of LpX, large abnormal lipid complexes known to be renally toxic.
“We are pleased to have received ODD for CER-001 just eight months after the ODD in Europe and one week after the first positive clinical results in COVID-19. These OD designations from the FDA underscore the importance of bringing this important therapeutic option to patients with LCAT Deficiency both as a kidney disease and as an ophthalmic disease,” commented Cyrille TUPIN, CEO of ABIONYX Pharma. “We look forward to presenting new clinical results in the coming months and providing additional insight into the potential of our Bio-HDL therapy platform in both kidney diseases and ophthalmologic diseases. The ODD paves the way for ABIONYX Pharma to launch a new strategic clinical development of the bio-HDL in kidney diseases and ophthalmologic diseases in the US.”
Orphan-drug designation is granted by the FDA to a drug or biologic intended to treat a rare disease or condition, which generally includes a disease or condition that affects fewer than 200,000 individuals in the U.S. Supporting the development and evaluation of new treatments for rare diseases is a key priority for the FDA. The designation is granted based on the mechanism of action of the drug or biologic taken into consideration with the pathogenesis of the disease or condition, its course and prognosis as well as the availability of treatments and/or resistance to available treatments.
Orphan drug designation qualifies sponsors for incentives including: tax credits for qualified clinical trials, exemption from user fees, and a potential for seven years of market exclusivity after approval.
