Novelion Therapeutics Announces Presentation of Positive Metreleptin Data at American Diabetes Association Scientific Sessions
Data Show Leptin Replacement Therapy Sustainably Decreased Weight Over Time in Patients with Low Baseline Leptin Levels
Company plans to initiate Phase 2 proof of concept study in hypoleptinemic metabolic disorder (HMD) by year-end
The study, titled “Efficacy of Metreleptin for Weight Loss in Overweight and Obese Adults With Low Leptin Levels,” was conducted in adults with low baseline leptin, defined as <16 ng/mL in females and <5 ng/mL in males, and Body Mass Index (BMI) levels between 27.5 and 38.0 kg/m2. The study assessed weight levels in these patients (n=267) following once-daily subcutaneous doses of 10 mg metreleptin, 20 mg metreleptin, or placebo over 24 weeks.
Patients with low leptin who received the 10 mg dose (n=74) or 20 mg dose (n=72) of metreleptin showed greater decreases in weight from baseline over the 24-week period compared to patients who received placebo (n=111). In addition, patients treated with the 20 mg dose displayed statistically significant weight loss by weeks 8-10, regardless of whether they had the highest or the lowest baseline levels of leptin. Notably, weight loss was maintained across dose levels for the entire six-month duration of the study, and patients with the lowest leptin levels benefitted most from metreleptin treatment.
Metreleptin was generally well-tolerated at both doses. The most common adverse events (AEs) were injection-site reactions, headache, fatigue, gastrointestinal events, and upper respiratory tract infection. Most AEs were mild to moderate in severity.
“We are very pleased with the data indicating metreleptin’s activity in a population of overweight and obese adults with low baseline leptin levels, who are in need of options to help them lose weight and control the metabolic complications associated with their disease,” said Dr.

Title: Efficacy of Metreleptin for Weight Loss in Overweight and Obese Adults With Low Leptin Levels
Abstract Number: 296-LB
About Hypoleptinemic Metabolic Disorder (HMD)
HMD is a spectrum of metabolic sequelae secondary to underlying leptin deficiency. These patients differ from epidemic “lifestyle” diseases such as common obesity, type 2 diabetes mellitus/insulin resistance and dyslipidemia, in that low leptin may be the driver of the metabolic dysfunction. Metreleptin is not intended to treat common obesity or adult onset diabetes; however, it may be a potential treatment option in a small segment of this population, specifically those patients with very low leptin levels.
Metreleptin is not currently approved for use in HMD. Metreleptin is only approved by the
IMPORTANT SAFETY INFORMATION
Highlights of Safety Information from U.S. Prescribing Information for MYALEPT (metreleptin U.S. brand name)
WARNING: RISK OF ANTI-METRELEPTIN ANTIBODIES WITH NEUTRALIZING ACTIVITY AND RISK OF LYMPHOMA
See full prescribing information for complete boxed warning.
Anti-metreleptin antibodies with neutralizing activity have been identified in patients treated with MYALEPT. The consequences are not well characterized but could include inhibition of endogenous leptin action and/or loss of MYALEPT efficacy. Worsening metabolic control and/or severe infection have been reported. Test for anti-metreleptin antibodies with neutralizing activity in patients with severe infections or loss of efficacy during MYALEPT treatment.
T-cell lymphoma has been reported in patients with acquired generalized lipodystrophy, both treated and not treated with MYALEPT. Carefully consider the benefits and risks of MYALEPT treatment in patients with significant hematologic abnormalities and/or acquired generalized lipodystrophy.
MYALEPT is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the MYALEPT REMS PROGRAM.
MYALEPT is contraindicated in general obesity not associated with congenital leptin deficiency and in patients with hypersensitivity to metreleptin.
WARNINGS AND PRECAUTIONS
Anti-metreleptin antibodies with neutralizing activity: Could inhibit endogenous leptin action and/or result in loss of MYALEPT efficacy. Test for neutralizing antibodies in patients with severe infections or loss of efficacy during MYALEPT treatment.
T-cell lymphoma: Carefully consider benefits and risks of treatment with MYALEPT in patients with significant hematologic abnormalities and/or acquired generalized lipodystrophy.
Hypoglycemia: A dose adjustment, including possible large reductions, of insulin or insulin secretagogue may be necessary. Closely monitor blood glucose in patients on concomitant insulin, or insulin secretagogue.
Autoimmunity: Autoimmune disorder progression has been observed in patients treated with MYALEPT. Carefully consider benefits and risks of MYLEPT treatment in patients with autoimmune disease.
Hypersensitivity reactions (e.g., anaphylaxis, urticaria or generalized rash) have been reported. Patients should promptly seek medical advice about discontinuation of MYALEPT if a hypersensitivity reaction occurs.
Benzyl Alcohol Toxicity: Preservative-free Water for Injection is recommended for use in neonates and infants.
Most common adverse reactions (≥10%) in clinical trials were headache, hypoglycemia, decreased weight, and abdominal pain.
USE IN SPECIAL POPULATIONS
MYALEPT should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. No adequate and well-controlled studies have been conducted with metreleptin in pregnant women. Nursing Mothers should discontinue drug or nursing.
For additional information, please see the U.S. Prescribing Information including Box Warning for MYALEPT.

Any statements contained herein which do not describe historical facts, including statements regarding our plans to initiate a Phase 2 proof of concept study in HMD and our expectations and beliefs about leptin replacement showing promise in the treatment of overweight and obese adult patients suffering from hypoleptinemic metabolic disorders who are characterized by very low leptin levels, are forward-looking statements which involve risks and uncertainties that could cause actual results to differ materially from those discussed in such forward-looking statements.
