BOSTON, Sept. 1, 2023 /PRNewswire/ -- Chiesi Global Rare Diseases, a business unit of the Chiesi Group established to deliver innovative therapies and solutions for people affected by rare diseases, today announced multiple presentations at the Society for the Study of Inborn Errors of Metabolism (SSIEM) Annual Symposium 2023 being held August 29 - September 1, 2023, in Jerusalem, Israel.

"There continues to be a general lack of awareness and a limited appreciation of the numerous unique challenges that people living with rare lysosomal storage diseases face every day," said Giacomo Chiesi, head of Chiesi Global Rare Diseases. "As a family business, and as a certified benefit corporation, we are focused on the long-term support of these patients and will continue to challenge the status quo by building awareness of unmet medical needs and embracing drug development risks. As we continue to significantly invest in innovation and seek opportunities to improve health outcomes, we are pleased to showcase multiple data presentations in Fabry disease and alpha-mannosidosis at the SSIEM symposium."

Four poster presentations at the SSIEM symposium feature analyses of the safety and efficacy of pegunigalsidase alfa, the company's PEGylated enzyme replacement therapy (ERT), in the treatment of Fabry disease.

In a poster, titled, "Pooled safety profile of pegunigalsidase alfa: an analysis of data from 142 patients in the pegunigalsidase alfa clinical program," John Bernat, M.D., Ph.D., University of Iowa Hospitals and Clinics, USA, is presenting an analysis of treatment-emergent adverse events (TEAEs), infusion-related reactions (IRRs) during the infusion or within two hours, and premedication use in four clinical trials and three long-term extension studies. This pooled analysis showed that pegunigalsidase alfa had an overall favorable safety profile with most (95.6%) TEAEs being of mild or moderate severity.

David Warnock, M.D., The University of Alabama at Birmingham, USA, is presenting a poster, titled, "Pooled analysis of the effect of pegunigalsidase alfa on renal function: Data from 113 patients in the pegunigalsidase alfa clinical trial program," that includes data from patients with more than 18 months of treatment across multiple trials. The results of this pooled analysis suggest that long-term pegunigalsidase alfa treatment provides continued renal function benefits in patients with Fabry disease.

In other Fabry disease posters, Dr. Bernat presents a post hoc analysis that found COVID-19 mRNA vaccines do not appear to increase the risk of IRRs or anti-drug antibodies in patients treated with pegunigalsidase alfa, and Ozlem Goker-Alpan, M.D., Lysosomal and Rare Disorders Research and Treatment Center, USA, describes the tolerability and safety of pegunigalsidase alfa in seven patients treated in an Expanded Access Program.

The company is also sponsoring a symposium on August 29 from 12:45-1:45pm IDT, "Creating a new roadmap: Advances in Fabry Disease Monitoring and Management," that is chaired by Dominique Germain, M.D., Ph.D., University of Versailles, Division of Medical Genetics, France. During the event, Derralynn Hughes, M.A., D.Phil., Royal Free NHS Foundation Trust and University College London, UK, is presenting an update on monitoring modalities, and Dawn Laney, M.S., Emory University School of Medicine, USA, is discussing how to incorporate the patient experience to guide monitoring and management.

In addition, two poster presentations at the SSIEM congress feature analyses of the impact of treatment with velmanase alfa in alpha-mannosidosis.

Benedicte Heron, M.D., Department of Pediatric Neurology, Reference Centre for Lysosomal Diseases, Armand Trousseau-La Roche Guyon University Hospital, France, is presenting a poster, titled, "Long-term efficacy of velmanase alfa treatment in patients with alpha mannosidosis: updated integrated analysis of data from phase I/II, III, and follow-up clinical trials," which concludes that the effect of the ERT on key efficacy outcomes appeared to be maintained over a long‑term period (up to 12 years) in pediatric and adult patients (N=33 patients, observation time 0.9 to 11.9 years).

Angela Messina, Ph.D., Consiglio Nazionale delle Ricerche (CNR), Italy, is presenting a poster, titled, "IgG glycosylation in patients with alpha-mannosidosis and the impact of enzyme replacement therapy." The results of this study suggest that IgG sialylation/galactosylation could offer a potential new pharmacodynamic biomarker for evaluating treatment benefits in patients with alpha-mannosidosis.

Indication and Important Safety Information for Elfabrio^® (pegunigalsidase alfa-iwxj)

Indication
Elfabrio^® (pegunigalsidase alfa-iwxj) is indicated for the treatment of adults with confirmed Fabry disease.

Important Safety Information

Prior to Elfabrio administration, consider pretreating with antihistamines, antipyretics, and/or corticosteroids. Inform patients and caregivers of the signs and symptoms of hypersensitivity reactions and infusion-associated reactions (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 Elfabrio administration and initiate appropriate medical treatment.
• If a mild to moderate hypersensitivity reaction or IAR occurs, consider slowing the infusion rate or temporarily withholding the dose.

In clinical trials, 20 (14%) Elfabrio-treated patients experienced hypersensitivity reactions.

Four Elfabrio-treated patients (3%) experienced anaphylaxis reactions that occurred within 5 to 40 minutes of the start of the initial infusion. The signs and symptoms of hypersensitivity reactions and anaphylaxis included headache, nausea, vomiting, throat tightness, facial and oral edema, truncal rash, tachycardia, hypotension, rigors, urticaria, intense pruritus, moderate upper airway obstructions, macroglossia, and mild lip edema.

In clinical trials, 41 (29%) Elfabrio-treated patients experienced one or more infusion-associated reactions, including hypersensitivity, nausea, chills, pruritus, rash, chest pain, dizziness, vomiting, asthenia, pain, sneezing, dyspnea, nasal congestion, throat irritation, abdominal pain, erythema, diarrhea, burning sensation, neuralgia, headache, paresthesia, tremor, agitation, increased body temperature, flushing, bradycardia, myalgia, hypertension, and hypotension.

A case of membranoproliferative glomerulonephritis with immune depositions in the kidney was reported during clinical trials. Monitor serum creatinine and urinary protein-to-creatinine ratio. If glomerulonephritis is suspected, discontinue treatment until a diagnostic evaluation can be conducted.

When switching to Elfabrio from a prior enzyme replacement therapy, the risk of hypersensitivity reactions and infusion-associated reactions may be increased in certain patients with pre-existing anti-drug antibodies (ADAs). Consider monitoring IgG and IgE ADAs and clinical or pharmacodynamic response (eg, plasma lyso-Gb3 levels).

The most common adverse reactions (≥15%) were infusion-associated reactions, nasopharyngitis, headache, diarrhea, fatigue, nausea, back pain, pain in extremity, and sinusitis.
