Amryt Announces Results from an Investigator Sponsored Study of Lomitapide in FCS

DUBLIN, Ireland, and Boston MA, March 30, 2021, Amryt (Nasdaq: AMYT, AIM: AMYT), a global, commercial-stage biopharmaceutical company dedicated to acquiring, developing and commercializing novel therapeutics to treat patients suffering from serious and life-threatening rare diseases, today announces efficacy and safety data from the “Lochnes” investigator sponsored study of lomitapide in Familial Chylomicronaemia Syndrome (“FCS”) which was conducted by expert lipidologists in Italy.

The study enrolled 18 adult patients across 3 sites. All patients had a genetic diagnosis of FCS and a history of pancreatitis. The median baseline fasting triglyceride level of patients was 1884 mg/dL. Patients were administered open-label treatment with escalating doses of lomitapide for 26 weeks. The median fasting triglyceride level at 26 weeks was 672 mg/dL representing a 70.5% median reduction versus baseline. 14 patients achieved a reduction in triglycerides to less than 1000 mg/dL and 13 of these achieved triglycerides of 750 mg/dL or below at 26 weeks.

Treatment with lomitapide was generally well tolerated and all patients completed 26 weeks of treatment. Adverse events were mild to moderate and mostly related to gastrointestinal tolerability and liver enzyme elevations. Liver MRI imaging revealed an increase in hepatic fat content which was between 30-50% at week 26 in 3 patients.

The company will now evaluate and analyse the full data set from the study and plans to discuss the potential development path forward with the FDA and the EMA.

Dr Mark Sumeray, Chief Medical Officer of Amryt, commented: “We are encouraged by the data from the study and look forward to our discussions with the respective health authorities to progress lomitapide as a potential treatment for FCS.”

Professor Maurizio Averna, Lead Investigator together with Professor Angelo B. Cefalù - Study Co-Investigator, commented: “The results of the study support the hypothesis that lomitapide may be a potential treatment for reducing triglycerides in FCS. Interestingly, at the end of the study, 14 out of 18 patients achieved triglyceride levels below 1000 mg/dL , which is considered the pancreatitis risk threshold.”

About Familial Chylomicronemia Syndrome (“FCS”) - FCS is a genetic disease caused by impaired function of the enzyme lipoprotein lipase (LPL), which results in elevated triglyceride levels and significant risk and disease burden. This may include unpredictable and potentially fatal acute pancreatitis as well as chronic complications due to permanent organ damage. It is estimated that there are between 3,000 to 5,000 people living with FCS worldwide. Patients must manage their triglyceride levels by adopting a strict, extremely low-fat diet of 10-20g of fat per day, which is incredibly challenging and does not remove the risk of pancreatitis and other symptoms of the disease.

About Lomitapide - Juxtapid®/ Lojuxta® (lomitapide) is approved as an adjunct to a low-fat diet and other lipid-lowering medicinal products for adults with the rare cholesterol disorder, Homozygous Familial Hypercholesterolaemia ("HoFH") in the US, Canada, Columbia, Argentina and Japan (under the trade name Juxtapid®) and in the EU and Brazil (under the trade name Lojuxta®). HoFH is a rare genetic disorder which impairs the body's ability to remove low density lipoprotein ("LDL") cholesterol ("bad" cholesterol) from the blood, typically leading to abnormally high blood LDL cholesterol levels in the body from before birth - often ten times more than people without HoFH - and subsequent aggressive and premature cardiovascular disease.

About Amryt
Amryt is a global commercial-stage biopharmaceutical company focused on acquiring, developing and commercializing innovative treatments to help improve the lives of patients with rare and orphan diseases. Amryt comprises a strong and growing portfolio of commercial and development assets.

Amryt’s commercial business comprises two orphan disease products – metreleptin (Myalept®/ Myalepta®) and lomitapide (Juxtapid®/ Lojuxta®).

Myalept® / Myalepta® (metreleptin) is approved in the US (under the trade name Myalept®) as an adjunct to diet as replacement therapy to treat the complications of leptin deficiency in patients with congenital or acquired generalized lipodystrophy (GL) and in the EU (under the trade name Myalepta®) as an adjunct to diet for the treatment of leptin deficiency in patients with congenital or acquired GL in adults and children two years of age and above and familial or acquired partial lipodystrophy (PL) in adults and children 12 years of age and above for whom standard treatments have failed to achieve adequate metabolic control.

Juxtapid®/ Lojuxta® (lomitapide) is approved as an adjunct to a low-fat diet and other lipid-lowering medicinal products for adults with the rare cholesterol disorder, Homozygous Familial Hypercholesterolaemia ("HoFH") in the US, Canada, Columbia, Argentina and Japan (under the trade name Juxtapid®) and in the EU, Israel and Brazil (under the trade name Lojuxta®). For additional information, please follow this link.

Amryt's lead development candidate, Filsuvez® (Oleogel-S10) is a potential treatment for the cutaneous manifestations of Junctional and Dystrophic Epidermolysis Bullosa (“EB”), a rare and distressing genetic skin disorder affecting young children and adults for which there is currently no approved treatment. Filsuvez® has been selected as the brand name for Oleogel-S10. The product does not currently have regulatory approval to treat EB.
Amryt’s pre-clinical gene therapy platform, AP103, offers a potential treatment for patients with Dystrophic EB, and is also potentially relevant to other genetic disorders.
