- If approved, metreleptin would be the first medication available in the EU to treat generalized and partial lipodystrophies

- More than 100 patients are currently treated with metreleptin via a compassionate use program in Europe

VANCOUVER, B.C., Dec. 22, 2016 (GLOBE NEWSWIRE) -- Novelion Therapeutics Inc. (NASDAQ:NVLN) (TSX:NVLN), a biopharmaceutical company dedicated to developing new standards of care for individuals living with rare diseases, today announced that its subsidiary has submitted a marketing authorization application (MAA) to the European Medicines Agency (EMA) seeking approval for metreleptin as replacement therapy to treat complications of leptin deficiency in patients with congenital or acquired generalized lipodystrophy (GL) and in a subset of patients with partial lipodystrophy (PL).

Metreleptin was granted orphan drug designation by the European Commission in July 2012, and if approved, carries 10 years of exclusivity in the EU. The company estimates the prevalence of GL is approximately one in one million people, and the prevalence of the subset of PL being targeted for approval is approximately one half to one in one million people. The company, through its subsidiary, will seek to market metreleptin in the EU under the tradename MYALEPTA®.

Mary Szela, chief executive officer of Novelion said, “There are a meaningful number patients in Europe that could benefit from metreleptin based upon the proposed indications and, if approved by EMA and reimbursement approvals in key markets are secured, we look forward to the opportunity to bring this important therapy to these patients. In addition, currently there are more than 100 patients on therapy via a pre-approval compassionate use program in certain markets in Europe, the majority of which are within the proposed indications. In addition to our efforts to target GL and a subset of patients with PL, we are continuing to focus on the potential of developing metreleptin for a variety of indications across a range of rare and metabolic diseases associated with low leptin over the coming years.”

“The application seeking approval for MYALEPTA in Europe is an important step in advancing our commitment to provide breakthrough therapies for patients with rare diseases,” said John Orloff, M.D., EVP, head of research and development for Novelion Therapeutics. “There have been limited options for treating complications of these rare forms of lipodystrophy, and we look forward to collaborating with regulatory authorities to bring forward this much needed treatment for adult and pediatric GL and a subset of PL patients affected by these serious, rare diseases.”

Generalized lipodystrophy (GL) and partial lipodystrophy (PL) are ultra-rare disorders characterized by loss of adipose tissue. Because the hormone leptin is made by fat tissue, patients with GL and PL have low levels of leptin, which regulates food intake and energy balance. Both GL and PL are associated with severe metabolic abnormalities, including hypertriglyceridemia, insulin resistance, and diabetes, which can result in life‑threatening co-morbidities such as acute pancreatitis, inflammation and fatty deposits in the liver (steatohepatitis), and accelerated plaque accumulation in the arteries (atherosclerosis).

Leptin is a naturally occurring hormone and an important regulator of energy homeostasis, fat and glucose metabolism. Metreleptin is an analog of leptin made through recombinant DNA technology and has been studied as a replacement therapy, in addition to diet, to treat the complications of leptin deficiency in patients with generalized or partial lipodystrophy.

Open-label studies with metreleptin showed significant reductions in HbA1c (a measure of blood sugar control), fasting glucose, and triglycerides. In the U.S., metreleptin is approved under the trade name MYALEPT® for the treatment of generalized lipodystrophy, and carries a boxed warning for the risks of anti-metreleptin antibodies with neutralizing activities and lymphoma. It is available only through the MYALEPT Risk Evaluation and Mitigation Strategy (REMS) program.

“Patients with generalized and partial forms of lipodystrophy have complex medical conditions with serious consequences. The options physicians have had to treat them have been significantly limited,” said David Araújo-Vilar, M.D., Ph.D., Universidade de Santiago de Compostela, Spain. “We look forward to the possibility of new options becoming available to advance the care of these patients.”

MYALEPT® (metreleptin for injection)
INDICATION and IMPORTANT SAFETY INFORMATION for MYALEPT® (metreleptin for injection)
INDICATION

MYALEPT® (metreleptin for injection) is a recombinant human 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 (metreleptin for injection) for the treatment of complications of partial lipodystrophy or for the treatment of liver disease, including nonalcoholic steatohepatitis (NASH), have not been established.
  • MYALEPT is not indicated for use in patients with HIV-related lipodystrophy or in patients with metabolic disease, including diabetes mellitus and hypertriglyceridemia, without concurrent evidence of congenital or acquired generalized lipodystrophy.

IMPORTANT SAFETY INFORMATION

WARNING: RISK OF ANTI-METRELEPTIN ANTIBODIES WITH NEUTRALIZING ACTIVITY AND RISK OF LYMPHOMA

  • Anti-metreleptin antibodies with neutralizing activity have been identified in patients treated with MYALEPT. The consequences of these neutralizing antibodies are not well characterized but could include inhibition of endogenous leptin action and/or loss of MYALEPT efficacy. Severe infection and/or worsening metabolic control have been reported. Test for anti-metreleptin antibodies with neutralizing activity in patients who develop severe infections or show signs suspicious for loss of MYALEPT efficacy during treatment. Contact Bristol Myers-Squibb at 1-866-216-1526 for neutralizing antibody testing of clinical samples.
  • 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 treatment with MYALEPT in patients with significant hematologic abnormalities and/or acquired generalized lipodystrophy.
  • Because of these risks associated with the development of anti-metreleptin antibodies that neutralize endogenous leptin and/or MYALEPT and the risk for lymphoma, MYALEPT is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the MYALEPT REMS PROGRAM.

CONTRAINDICATIONS
MYALEPT (metreleptin for injection) is contraindicated in patients with:

  • General obesity not associated with congenital leptin deficiency. MYALEPT has not been shown to be effective in treating general obesity, and the development of anti-metreleptin antibodies with neutralizing activity has been reported in obese patients treated with MYALEPT
  • Prior severe hypersensitivity reactions to metreleptin or to any of the product components. Known hypersensitivity reactions have included urticaria and generalized rash.

WARNINGS AND PRECAUTIONS

Risk for Development of Antibodies that Neutralize Endogenous Leptin and/or MYALEPT
Anti-metreleptin antibodies with in vitro neutralizing activity to leptin associated with adverse events consistent with loss of endogenous leptin activity and/or loss of efficacy have been identified in two patients with generalized lipodystrophy treated with MYALEPT (severe infections, increases in HbA1c and triglycerides), and in three patients without lipodystrophy who received MYALEPT in clinical studies (excessive weight gain, development of glucose intolerance or diabetes mellitus). The clinical implications associated with development of anti-metreleptin antibodies with neutralizing activity are not well-characterized at this time due to the small number of reports. Test for anti-metreleptin antibodies with neutralizing activity in patients who develop severe infections or show signs suspicious for loss of MYALEPT efficacy during treatment.

Lymphoma

  • Three cases of T-cell lymphoma have been reported in the MYALEPT lipodystrophy program; all three patients had acquired generalized lipodystrophy. Two of these patients were diagnosed with peripheral T-cell lymphoma while receiving MYALEPT. Both had immunodeficiency and significant hematologic abnormalities including severe bone marrow abnormalities before the start of MYALEPT treatment. A separate case of anaplastic large cell lymphoma was reported in a patient receiving MYALEPT (metreleptin for injection) who did not have hematological abnormalities before treatment.
  • Lymphoproliferative disorders, including lymphomas, have been reported in patients with acquired generalized lipodystrophy not treated with MYALEPT. A causal relationship between MYALEPT treatment and the development and/or progression of lymphoma has not been established. Acquired lipodystrophies are associated with autoimmune disorders, and autoimmune disorders are associated with an increased risk of malignancies including lymphomas.
  • The benefits and risks of MYALEPT treatment should be carefully considered in patients with acquired generalized lipodystrophy and/or those with significant hematologic abnormalities (including leukopenia, neutropenia, bone marrow abnormalities, lymphoma and/or lymphadenopathy).

MYALEPT REMS Program
MYALEPT is available only through a restricted distribution program under a REMS, called the MYALEPT REMS Program, because of the risks associated with the development of anti-metreleptin antibodies that neutralize endogenous leptin and/or MYALEPT and the risk for lymphoma see Warnings and Precautions section.
