(6.1) To report SUSPECTED ADVERSE REACTIONS, contact Chiesi USA, Inc. at 1-888-661-9260 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trial of another drug and may not reflect the rates observed in clinical practice. Adverse Reactions From Trial 2 The safety of ELFABRIO in adults with confirmed Fabry disease who had been previously treated with agalsidase beta was evaluated in Trial 2 which included a total of 52 ELFABRIO-treated patients (29 male, 23 female aged 20 to 60 years old) with Fabry disease [see Clinical Studies (14)]. Patients received 1 mg/kg of ELFABRIO given intravenously every 2 weeks for at least 104 weeks. The most common adverse reactions (≥15%) reported with ELFABRIO were infusion-associated reactions which occurred in 17 patients (32%); followed by, nasopharyngitis and headache each in 11 patients (21%); diarrhea in 10 patients (19%); fatigue and nausea each in 9 patients (17%); and back pain, pain in extremity, and sinusitis each in 8 patients (15%). One ELFABRIO-treated patient experienced a severe hypersensitivity reaction during the first infusion. The patient withdrew from the trial following a moderate hypersensitivity reaction during the second infusion. Table 3 lists adverse reactions reported in at least 5% of ELFABRIO-treated patients in Trial 2. Table 3: Adverse Reactions in Adults With Fabry Disease (Trial 2) 1 Adverse Reaction ELFABRIO N=52 n (%) Agalsidase beta N=25 n (%) Infusion-Associated Reaction 2,4 17 (32) 8 (32) Nasopharyngitis 11 (21) 4 (16) Headache 11 (21) 5 (20) Diarrhea 10 (19) 6 (24) Fatigue 9 (17) 4 (16) Nausea 9 (17) 3 (12) Back pain 8 (15) 5 (20) Pain in Extremity 8 (15) 4 (16) Sinusitis 8 (15) 3 (12) Abdominal Pain 6 (12) 0 (0) Proteinuria 6 (12) 0 (0) Hypersensitivity 3,4 5 (9) 4 (16) Upper Respiratory Tract Congestion 4 (8) 0 (0) Neuralgia 4 (8) 0 (0) Peripheral Neuropathy 3 (6) 0 (0) Sciatica 3 (6) 0 (0) Infusion Site Extravasation 3 (6) 0 (0) Hematuria 3 (6) 0 (0) 1 Adverse reactions were those that occurred in ≥ 5% of ELFABRIO-treated patients. 2 “Infusion-associated reaction” includes nausea, vomiting, abdominal pain, diarrhea, fatigue, chills, malaise, non-cardiac chest pain, hypersensitivity, body temperature increased, burning sensation, neuralgia, agitation, throat irritation, pruritic rash, and flushing. Events occurring within 24 hours. 3 “Hypersensitivity” includes macular rash, pruritic rash, and face swelling. Events occurring within 24 hours. 4 The events of hypersensitivity and pruritic rash fall in both hypersensitivity and IAR categories.

(2.3) For instructions on preparation (including dilution), storage, and administration (including rates for the initial 4-6 infusions for ERT-experienced and ERT-naïve patients), see Full Prescribing Information. (2.4, 2.5, 2.6) 2. 1 Recommendations Prior to ELFABRIO Treatment Pretreatment In enzyme replacement therapy (ERT)-experienced patients, if pretreatment with antihistamines, antipyretics, and/or corticosteroids was used prior to ERT administration, consider similar pretreatment with these medications before the first several ELFABRIO infusions. After 4 to 6 ELFABRIO infusions, a stepwise decrease in the pretreatment medication dose(s) and/or discontinuation of the pretreatment medication(s) may be considered if treatment with ELFABRIO was tolerated. In ERT-naïve patients, prior to ELFABRIO administration, pre-treating with antihistamines, antipyretics, and/or corticosteroids may be considered [see Warnings and Precautions (5.1, 5.2)]. Medical Support Appropriate medical support measures including cardiopulmonary resuscitation equipment should be readily available during ELFABRIO administration. 2. 2 Recommended Dosage and Administration The recommended dosage of ELFABRIO, based on actual body weight, is 1 mg/kg administered by intravenous infusion every 2 weeks. The initial recommended ELFABRIO infusion rates for ERT-experienced or ERT-naïve patients are based on actual body weight [see Tables 1 and 2]. If one or more doses are missed, restart ELFABRIO treatment as soon as possible, maintaining the 2 week interval between infusions thereafter. Do not double a dose to compensate for a missed dose. 2. 3 Administration Modifications Due to Hypersensitivity Reactions and/or Infusion-Associated Reactions In the event of a severe hypersensitivity reaction (e.g., anaphylaxis) or severe infusion-associated reaction (IAR), immediately discontinue ELFABRIO administration and initiate appropriate medical treatment. For additional recommendations in the event of a severe hypersensitivity reaction or IAR, see Warnings and Precautions (5.1, 5.2). 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 or slowing the infusion rate by 25% to 50% [see Dosage and Administration (2.6)], and initiating appropriate medical treatment [see Warnings and Precautions (5.1, 5.2)]. If symptoms persist despite holding or slowing the infusion, stop the infusion and monitor the patient. Consider re-initiating the infusion within 7 to 14 days at 25% to 50% of the rate at which the reaction occurred with appropriate pretreatment. If symptoms subside after holding the infusion, resume infusion at a 25% to 50% reduced rate as tolerated.

Pegunigalsidase alfa en el embarazo

Cita de la parte sobre embarazo (Pregnancy) de la etiqueta aprobada por la FDA. Se muestra en inglés. Pregunte a su médico antes de tomar cualquier medicamento si está embarazada o planea estarlo.

Risk Summary There are no available data on ELFABRIO use in pregnant females to evaluate a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes; however, as an enzyme replacement, ELFABRIO is not expected to cause adverse outcomes. Animal reproduction studies have been conducted with pegunigalsidase alfa-iwxj in pregnant rats and rabbits.

No adverse effects on embryofetal development were observed in pregnant rats intravenously administered pegunigalsidase alfa-iwxj twice per week at exposures up to 3.6 times that of the maximum recommended human dose (MRHD) (based on area under the concentration-time curve (AUC)). Maternal toxicity was observed in pregnant rabbits intravenously administered pegunigalsidase alfa-iwxj twice per week at doses that were ≥ 3.2 times the MRHD (based on human equivalent dose) [see Data]. The estimated background risk of major birth defects and miscarriage in the indicated population is unknown. All pregnancies have a background risk of birth defect, loss or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. There is a pregnancy safety study for ELFABRIO. If a patient becomes pregnant while receiving ELFABRIO, healthcare providers should report ELFABRIO exposure by calling 1-888-661-9260 or visiting https://chiesirarediseases.com/contact-us/medical-information-form. Data Animal Data In an embryofetal development study in the rat, pegunigalsidase alfa-iwxj was administered during the period of organogenesis on gestation day 6, 9, 12, and 15. No maternal or fetal adverse effects were noted at exposures that were up to 3.6-fold greater than the recommended dose of 1 mg/kg every two weeks. In an embryofetal development study in the rabbit, administration of pegunigalsidase alfa-iwxj during the period of organogenesis on gestation day 6, 9, 12, 15, and 18, resulted in maternal toxicity, including maternal mortality, decreased body weight, and decreased feed consumption. These effects were observed at exposures that were ≥ 3.2-fold greater than the recommended dose of 1 mg/kg every two weeks. Adverse embryofetal effects included abortion, increased late resorptions, number of does with resorptions, and increased post-implantation loss at exposures that were 6.5 fold greater than the recommended dose of 1 mg/kg every two weeks. Decreased fetal body weight was observed at exposures that were ≥ 3.2 times greater than the recommended dose of 1 mg/kg every two weeks. There was no increase in fetal external, skeletal, or visceral malformations.
