BOSTON, Feb. 16, 2023 /PRNewswire/ -- Chiesi Global Rare Diseases, a business unit of Chiesi Farmaceutici S.p.A., an international research-focused healthcare Group (Chiesi Group), announced today that the U.S. Food and Drug Administration (FDA) has approved Lamzede^® (velmanase alfa-tycv) for the treatment of non-central nervous system manifestations of alpha-mannosidosis (AM) in adult and pediatric patients. AM is an ultra-rare, progressive lysosomal storage disorder caused by deficiency in the enzyme α-mannosidase.

"Today's approval of Lamzede represents a major milestone for people living with alpha-mannosidosis. Lamzede is the first and only enzyme replacement therapy approved for alpha-mannosidosis in the United States, an achievement based on years of clinical development, as well as the dedication of our employees, clinicians, patients and their families," said Giacomo Chiesi, head of Chiesi Global Rare Diseases. "Alpha-mannosidosis presents with a variety of symptoms including impaired hearing, speech and mobility that progress from childhood into adulthood and is often under-recognized, causing some patients to be left undiagnosed or untreated. Lamzede is designed to provide an exogenous source of the α-mannosidase enzyme and we look forward to offering this medicine to patients in the United States who are eagerly awaiting a treatment option."

The prevalence of AM is approximately one in every 500,000 to one in every 1,000,000 babies born worldwide. AM results in the body's cells being unable to properly break down certain groups of complex sugars. The buildup of sugars can affect many of the body's organs and systems. Effects of the disease vary significantly from person to person and progress over time. Symptoms may change as a patient gets older and can include recurrent chest and ear infections, hearing loss, distinctive facial features, muscle weakness, skeletal and joint abnormalities, visual abnormalities, and cognitive abnormalities.

Lamzede is a recombinant form of human alpha-mannosidase intended to provide or supplement natural alpha-mannosidase, an enzyme that is involved in the degradation of mannose–rich oligosaccharides to prevent their accumulation in various tissues in the body. In 2018, Chiesi Group received marketing authorization from the European Commission for Lamzede for the treatment of non-neurological manifestations in patients with mild to moderate AM.

Important Safety Information

Indication

Lamzede^® (velmanase alfa-tycv) is indicated for the treatment of non-central nervous system manifestations of alpha-mannosidosis in adult and pediatric patients.

Important Safety Information

WARNING: SEVERE HYPERSENSITIVITY REACTIONS

Hypersensitivity Reactions Including Anaphylaxis

Patients treated with Lamzede have experienced hypersensitivity reactions, including anaphylaxis. Appropriate medical support measures, including cardiopulmonary resuscitation equipment, should be readily available during Lamzede administration. If a severe hypersensitivity reaction (e.g., anaphylaxis) occurs, discontinue Lamzede immediately and initiate appropriate medical treatment. In patients with severe hypersensitivity reaction, a desensitization procedure to Lamzede may be considered.

Considerations Due to Hypersensitivity Reactions and/or Infusion-Associated Reactions (IARs)

Prior to Lamzede administration, consider pretreating with antihistamines, antipyretics, and/or corticosteroids. Inform patients and caregivers of the signs and symptoms of hypersensitivity reactions and IARs and instruct them to seek medical care immediately if such symptoms occur.

If a severe hypersensitivity reaction (including anaphylaxis) or severe IAR occurs, immediately discontinue Lamzede administration and initiate appropriate medical treatment.
In the event of a mild to moderate hypersensitivity reaction or a mild to moderate IAR, consider temporarily holding the infusion for 15 to 30 minutes, slowing the infusion rate to 25% to 50% of the recommended rate, and initiating appropriate medical treatment.

Hypersensitivity Reactions Including Anaphylaxis

Anaphylaxis and severe hypersensitivity signs and symptoms included cyanosis, hypotension, emesis, urticaria, erythema, facial swelling, pyrexia, and tremor.

Infusion-Associated Reactions (IARs)

The most frequent symptoms of IARs that occurred in >10% of the population were pyrexia, chills, erythema, vomiting, cough, urticaria, rash, and conjunctivitis.

Females of Reproductive Potential

Advise females of reproductive potential to use effective contraception during treatment and for 14 days after the last dose if Lamzede is discontinued. For females of reproductive potential, verify that the patient is not pregnant prior to initiating treatment with Lamzede.

Embryo-Fetal Toxicity

Based on findings from animal reproduction studies, Lamzede may cause embryo-fetal harm when administered to a pregnant female.

Common Adverse Reactions

The most common adverse reactions (incidence >20%) are hypersensitivity reactions including anaphylaxis, nasopharyngitis, pyrexia, headache, and arthralgia.
