The company also announced the presentation of immunogenicity and tolerability data from its pegunigalsidase alfa clinical trial program in Fabry disease, as well as analyses of the prevalence, diagnosis, and progression of these rare lysosomal storage disorders. The data are being presented during the 20th Annual WORLDSymposium™ Research Meeting that is being held February 4-9, 2024, in San Diego, California.
“This year’s WORLDSymposium marks a significant moment for people living with rare lysosomal storage disorders including alpha-mannosidosis and Fabry disease, and their healthcare teams including clinicians and nurses, who now have access to recently approved treatment options and an important opportunity to understand the impact of these therapies and the barriers that must be addressed to improve diagnosis and disease management,” said Giacomo Chiesi, head of Chiesi Global Rare Diseases. “Our company is driven by a commitment to rare disease communities around the world and we are taking full advantage of this conference to share our extensive clinical research in AM, which now spans more than a decade, and in Fabry disease, where we are continuing to evaluate data from our comprehensive development program. We are also emphasizing the importance of the caregiver and patient voice, reporting results from a range of surveys and analyses, hosting symposia, and presenting a special film screening that will help healthcare professionals identify and treat people in these communities in the years ahead.” Results from long-term treatment with velmanase alfa in AM In an oral session, Prof. Nathalie Guffon, M.D., Reference Centre of inherited metabolic disease in Femme Mère Enfant Hospital, Hospices Civils of Lyon, France, is presenting results of an analysis that evaluated long‑term efficacy of up to 12 years of treatment with velmanase alfa, which is the first and only enzyme replacement therapy (ERT) available for people with AM. Pooled analyses demonstrate tolerability of pegunigalsidase alfa in Fabry disease and low incidence of de novo anti-drug antibodies Several poster presentations are highlighting immunogenicity and tolerability data from the pegunigalsidase alfa clinical trial program in Fabry disease. John Bernat, M.D., Ph.D., Medical Director of the Iowa Lysosomal Storage Disorders Center, is presenting a poster describing characteristics of anti-drug antibodies (ADAs) reacting with pegunigalsidase alfa, and the patients who develop ADAs, using data from an integrated clinical trial dataset. The analysis includes 108 patients, 27 (25%) of whom were ADA+ before receiving their first dose of pegunigalsidase alfa. There was a low incidence of de novo ADAs (n=17) occurring predominantly in the first year of treatment with pegunigalsidase alfa. Neutralizing antibodies were detected in <25% of patients with de novo ADAs versus in almost all patients who were ADA+ at baseline. In separate poster presentations, Derralynn Hughes, M.D., Professor of Experimental Haematology at the University College London, and Ankit Mehta, M.D., FASN, Baylor University Medical Center, are sharing results from analyses of the tolerability of pegunigalsidase alfa across the clinical program per dosing regimen and prior enzyme replacement therapy (ERT) experience, respectively. Dr. Hughes found that less than a third of patients receiving pegunigalsidase alfa experienced infusion related reactions (IRRs), most of which occurred from the start of the infusion until up to two hours after its end among patients with pre-existing or de novo ADAs. The frequency of IRRs decreased over time and in parallel with a decrease in premedication use among those switching from prior ERT. Dr. Mehta found that IRRs from the start of the infusion until up to two hours after its end occurred in about a quarter of either ERT-naive or ERT-switch patients following treatment with pegunigalsidase alfa. Most of these IRRs were mild to moderate in severity and occurred predominantly in the first year after initiating the therapy. Surveys and epidemiological analyses shed new light on the prevalence, diagnosis, and progression of AM and Fabry disease Chiesi Global Rare Diseases is announcing five additional presentations focused on improving awareness and understanding of the patient experience with rare lysosomal storage disorders including AM and Fabry disease.
Chiesi Global Rare Diseases is sponsoring three satellite symposia during WORLDSymposium to review perspectives on the management of Fabry disease and AM including insights from clinicians, caregivers, and patients. The company is also presenting a special screening of “Rare Land,” a film focused on AM, with an expert panel featuring Robert Hopkin, M.D., Clinical Geneticist at Cincinnati Children’s Hospital Medical Center and Martin Magner, M.D., Ph.D., Department of Paediatrics and Hereditary Metabolic Disorders of the General University Hospital of Prague. In addition, the company is presenting during the Industry Expert Theater session and is participating in the Patient Voice and Preference meeting. 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.
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. Please see Full Prescribing Information for Elfabrio. Indication and Important Safety Information for Lamzede® (velmanase alfa-tycv) 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
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.
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.
