Novelion Therapeutics Announces Presentation of Metreleptin Data at American Association of Clinical Endocrinology
The study titled "Impact of Metreleptin on Hepatomegaly in Patients with Generalized Lipodystrophy" suggests treatment with metreleptin may reduce liver volume in patients with enlarged liver (hepatomegaly) resulting from complications of generalized lipodystrophy (GL). The study also demonstrated improvements from baseline of key metabolic parameters, including hemoglobin A1c (HbA1c), liver enzymes and triglycerides.
The post-hoc analysis of an open-label, prospective study in patients with GL assessed both the impact on liver volume and key metabolic parameters when patients were treated with metreleptin as leptin replacement therapy. Of the 34 evaluable patients, 22 had baseline liver volumetric measurements using MRI; all 22 patients had an enlarged liver. Normal liver volume was defined as less than 25 mL/kg of body weight.
The post-hoc analysis completed by
For patients assessed within one year of initiating treatment with metreleptin (N=21), liver volume decreased an average of 25 percent. The mean treatment duration was 10 months. Among these same patients who had additional follow ups after one year (N=14) and had a mean duration of metreleptin treatment of 46 months, liver volume decreased by 35 percent.
The most commonly reported adverse events occurring in more than 10 percent of patients were abdominal pain, hypoglycemia, ear infection, fatigue, proteinuria, back pain, diarrhea, headache, menorrhagia, nausea, ovarian cyst, upper respiratory tract infection and weight decline.
"GL patients lack fat cells and the absence of adipocytes can lead to the accumulation of fat in the liver that can potentially progress to various forms of liver disease," said
Patients treated with metreleptin also experienced clinically meaningful reductions from baseline in HbA1c, liver enzymes (both AST and ALT) and triglycerides, a type of fat in the blood.
Novelion believes that metreleptin may demonstrate clinical results in a wide range of low leptin-mediated rare and metabolic diseases. John Orloff, MD, executive vice president and head of research and development for Novelion, stated, "Analysis like this, combined with 14 years of additional patient data, provides evidence supporting the implications of low leptin levels on various physiologic functions. We are currently evaluating conducting clinical trials to investigate the use of metreleptin in multiple other low leptin-mediated conditions."
Lipodystrophy syndromes (LD) are ultra-rare disorders characterized by the irreversible loss of adipose tissue. In patients with lipodystrophy syndromes, levels of leptin are often very low. Leptin is a naturally occurring hormone produced in adipose tissue and is an important regulator of energy homoeostasis, fat and glucose metabolism, reproductive capacity, and other diverse physiological functions.
With GL, the loss of fat affects the whole body. With partial lipodystrophy, the loss of fat typically occurs in the arms, legs, head and trunk regions, while accumulation of fat may occur in other areas of the body, including the neck, face and intra-abdominal regions. Metreleptin is approved in the
MYALEPT® (metreleptin) for injection is a leptin analog indicated as an adjunct to diet as replacement therapy to treat the complications of leptin deficiency in patients with congenital or acquired generalized lipodystrophy. LIMITATIONS OF USE: The safety and effectiveness of MYALEPT for the
treatment of complications of partial lipodystrophy or for the treatment of liver disease, including nonalcoholic steatohepatitis (
Anti-metreleptin antibodies with neutralizing activity have been identified in patients treated with MYALEPT. T-cell lymphoma has been reported in patients with acquired generalized lipodystrophy, both treated and not treated with MYALEPT. For more detailed information, please see additional Important Safety Information and the Prescribing Information, including boxed warning, for MYALEPT.
MYALEPT is available only through a restricted program called the MYALEPT REMS PROGRAM.
