Dec 13An FDA panel voted 10-2 that metreleptin´s benefits didn´t outweigh its risks for patients with partial lipodystrophy (LD) and hypertriglyceridaemia and diabetes. Instead, the panel voted 11-1 in favour of the drug in patients with generalized LD, a complete loss of leptin, which is a very small patient population. An FDA decision on licensing is expected by 24 Feb 14 [9].
Dec 13EU filing planned for 2015 [11].
Jun 13EU filing will be 1H 14 [7].

Jul 12Orphan designation granted by the European Commission to Aptiv Solutions (UK) Limited for metreleptin for the treatment of a number of lipodystrophies: familial partial lipodystrophy (EU/3/12/1022), Lawrence syndrome (EU/3/12/1024), Berardinelli-Seip syndrome (EU/3/12/1025) and Barraquer-Simons syndrome (EU/3/12/1023) [5].
Apr 12US filing has been completed for the use of metreleptin to treat diabetes and/or hypertriglyceridaemia in paediatric and adult patients with rare forms of lipodystrophy. Amylin has requested priority review [4].

Trial or other data

Feb 21NICE recommends metreleptin for use in England and Wales as an option for treating the complications of leptin deficiency in lipodystrophy for people who are 2 years and over and have generalised lipodystrophy. Also as an option for treating the complications of leptin deficiency in lipodystrophy for people who are 12 years and over, have partial lipodystrophy, and do not have adequate metabolic control despite having standard treatments (it is only recommended if they have an HbA1c level above 7.5%, or fasting triglycerides above 5.0 mmol/litre, or both) [29].
Dec 13The FDA briefing for its advisory panel states that metreleptin appears to be effective in a subgroup of patients with generalized lipodystrophy (congenital or acquired) with severe insulin resistance resulting in diabetes mellitus and/or severe hypertriglyceridaemia not adequately controlled with other therapies. However, as the pivotal study did not have a control group, it is unclear whether the benefit was due to the drug or by a change of diet or compliance with other medicines. The FDA reviewers raise concerns about the potential of metreleptin to cause T-cell lymphoma and affect the immune system [8].
May 13Bristol-Myers Squibb and AstraZeneca announced the results from a sub-group analysis in patients 12 to <18), and data were analyzed at month 12 of metreleptin treatment, where available (n=27). In adolescents, metreleptin reduced mean HbA1c from 9.8±1.8% at baseline to 7.7±1.7% at month 12 (mean decrease 2.3±0.4%) and triglycerides from 1378±2024 mg/dL at baseline to 385±446 mg/dL at month 12 (mean decrease of 44±14%). Mean ALT decreased from 105±97 U/L to 59±108 U/L ( mean decrease of 46±40%), and mean AST decreased from 87±89 U/L to 57±118 U/L (mean decrease of 31±38%). In younger children, confirmed diabetes and hypertriglyceridaemia were uncommon; however, mean LFTs were markedly elevated at baseline and decreased with metreleptin treatment (mean ALT decreased from 193±202 U/L to 155±274 U/L (mean decrease 38±47%, and AST decreased from 119±112 U/L to 90±144 U/L (mean decrease 30±29%). Reductions in ALT and AST did not reach statistical significance due to the small sample size but were clinically meaningful. The most common AE related to treatment with metreleptin were decreased weight (n=3, 7.7%), hypoglycaemia (n=3, 7.7%), fatigue (n=2, 5.1%), and nausea (n=2, 5.1%) [6].
Aug 12BMS buy out Amylin
Nov 08Amylin is investigating metreleptin in an open label clinical trial (NCT00677313) in 30 patients (aged ≥5) for the treatment of diabetes mellitus and/or hypertriglyceridaemia associated with lipodystrophy. The trial started Nov 2008 and is due to complete Nov 2011 [2]
Apr 06Placebo controlled PIII (NCT00896298) trial of metreleptin in pts with lipodystrophy started. 24 pts aged btn 6 yrs & 70 yrs with partial or generalised lipodystrophy will be recruited in the US. Metreleptin will be injected subcutaneously twice a day, given at 100% of the estimated replacement dose during the first month, which is a dosage of 0.03mg/kg for female children, 0.04mg/kg for adult females, & 0.02 mg/kg for all males, & then at 200% subsequently. The study will complete in Jul 12 [3].
Jan 06Lipodystrophy syndromes are characterized by abnormalities in adipose tissue distribution with loss of subcutaneous fat, and often manifest in childhood or adolescence. It is associated with multiple severe metabolic abnormalities including extreme insulin resistance, very high triglyceride levels, difficult-to-control diabetes and hepatic steatosis resulting in a high risk of acute pancreatitis, accelerated atherosclerosis, diabetes complications and liver cirrhosis. Patients with lipodystrophy typically also have a deficiency of leptin, a hormone secreted by fat cells that plays a key role in regulating metabolism [1].
