Comment ça marche

12.1 Mechanism of Action Iptacopan binds to Factor B of the alternative complement pathway and regulates the cleavage of C3, generation of downstream effectors, and the amplification of the terminal pathway. In PNH, intravascular hemolysis (IVH) is mediated by the downstream membrane attack complex (MAC), while extravascular hemolysis (EVH) is facilitated by C3b opsonization. Iptacopan acts proximally in the alternative pathway of the complement cascade to control both C3b-mediated EVH and terminal complement-mediated IVH. In IgAN, the deposition of galactose deficient IgA1 (Gd-IgA1) containing immune complexes in the kidney locally activates the alternative complement pathway which is thought to contribute to the pathogenesis of IgAN. By binding to Factor B, iptacopan inhibits the alternative pathway. In C3G, overactivation of the alternative complement pathway leads to C3 cleavage within the glomeruli resulting in C3 deposition and inflammation, which are thought to contribute to the pathogenesis of C3G. By binding to Factor B, iptacopan inhibits the alternative pathway.

Posologie et Administration

2 DOSAGE AND ADMINISTRATION 200 mg orally twice daily with or without food. ( 2.2 ) 2.1 Recommended Vaccination and Prophylaxis for Encapsulated Bacterial Infections Vaccinate patients against encapsulated bacteria, including Streptococcus pneumoniae and Neisseria meningitidis (serogroups A, C, W, Y and B) , according to current ACIP recommendations at least 2 weeks prior to initiation of FABHALTA [see Warnings and Precautions (5.1)] . If urgent FABHALTA therapy is indicated in a patient who is not up to date with vaccines for Streptococcus pneumoniae and Neisseria meningitidis according to ACIP recommendations, provide the patient with antibacterial drug prophylaxis and administer these vaccines as soon as possible [see Warnings and Precautions (5.1)] . Healthcare providers who prescribe FABHALTA must enroll in the FABHALTA REMS [see Warnings and Precautions (5.2)] . 2.2 Recommended Dosage The recommended dosage of FABHALTA is 200 mg orally twice daily without regard to food. Swallow capsules whole. Do not open, break, or chew capsules. If a dose or doses are missed, advise the patient to take one dose of FABHALTA as soon as possible (even if it is soon before the next scheduled dose) and then to resume the regular dosing schedule. 2.3 PNH Patients Switching From Anti-C5 (eculizumab, ravulizumab) to FABHALTA To reduce the potential risk of hemolysis with abrupt discontinuation of other PNH therapies: For patients switching from eculizumab, initiate FABHALTA no later than 1 week after the last dose of eculizumab. For patients switching from ravulizumab, initiate FABHALTA no later than 6 weeks after the last dose of ravulizumab. There is no available information regarding the timeframe for initiation of FABHALTA after other PNH therapies.

Description of Select Adverse Reactions (graded per NCI CTCAE Version 4.03 unless noted otherwise) Platelet Count Decreased Of the 37 FABHALTA-treated patients who had normal platelet counts at baseline in APPLY-PNH, 43% experienced any Grade thrombocytopenia during the randomized treatment period. Three FABHALTA-treated patients in APPLY-PNH experienced decreased platelets that worsened to Grade ≥ 3 from baseline (one patient with normal platelets that worsened to Grade 4, one patient with baseline Grade 1 that worsened to Grade 4, and one patient with baseline Grade 3 that worsened to Grade 4). Immunoglobulin A Nephropathy (IgAN) The safety of FABHALTA was evaluated in APPLAUSE-IgAN, a randomized placebo-controlled, double-blind clinical study in adults with IgAN (eGFR ≥ 20 mL /min/1.73 m 2 at baseline). The data below reflect FABHALTA exposure in 235 patients with IgAN (eGFR ≥ 20 mL/min/1.73 m 2 at baseline) with a median duration of 43 weeks (up to 104 weeks) in APPLAUSE-IgAN.

Pharmacocinétique

12.3 Pharmacokinetics Absorption Following oral administration, iptacopan reached peak plasma concentrations approximately 2 hours post dose. At the recommended dosing regimen of 200 mg twice daily, steady state is achieved in approximately 5 days with minor accumulation (1.4-fold). Effect of Food Based on a food-effect study in healthy volunteers, a high-fat meal did not affect the exposure of iptacopan to a clinically meaningful degree. Distribution Iptacopan showed concentration-dependent plasma protein binding due to binding to the target Factor B in the systemic circulation. Iptacopan was 75% to 93% protein bound in vitro at the relevant clinical plasma concentrations. After administration of iptacopan 200 mg twice daily, the apparent volume of distribution at steady state was approximately 288 L. Elimination The terminal half-life (t 1/2 ) of iptacopan at steady state is approximately 25 hours after administration of FABHALTA 200 mg twice daily. The apparent clearance of iptacopan at steady state is 8 L/h after administration of FABHALTA 200 mg twice daily. Metabolism Metabolism is a predominant elimination pathway for iptacopan with approximately 50% of the dose attributed to oxidative pathways. Metabolism of iptacopan includes N-dealkylation, O-deethylation, oxidation, and dehydrogenation, mostly driven by CYP2C8 (98%) with a small contribution from CYP2D6 (2%). Iptacopan undergoes Phase 2 metabolism through glucuronidation by UGT1A1, UGT1A3, and UGT1A8. In plasma, iptacopan was the major component, accounting for 83% of the drug-related species. Two acyl glucuronides were the only metabolites detected in plasma and were minor, accounting for 8% and 5% of the drug-related species. Iptacopan metabolites are not pharmacologically active. Excretion In a human study, following a single 100 mg oral dose of [ 14 C]-iptacopan, mean total excretion of radioactivity (iptacopan and metabolites) was 72% in the feces and 25% in the urine, for a total mean excretion of > 96% of the dose. Specifically, 18% of the dose was excreted as parent iptacopan in the urine, and 17% of the dose was excreted as parent iptacopan in feces. Linearity/Non-linearity At doses between 25 mg and 200 mg twice daily, iptacopan was overall less than dose proportional. However, oral doses of 100 mg and 200 mg were approximately dose proportional. Specific Populations A population pharmacokinetic (PK) analysis was conducted on iptacopan data from 234 patients. Age, body weight, race, and gender did not have a clinically significant effect on iptacopan PK. Patients with Renal Impairment There were no clinically significant differences in the exposure of FABHALTA between patients with an eGFR in the range of 25 to < 90 mL/min compared to those with normal eGFR. No data are currently available in patients on dialysis. Patients with Hepatic Impairment In a study in subjects with normal hepatic function and patients with mild (Child-Pugh class A), moderate (Child-Pugh class B), or severe hepatic impairment (Child-Pugh class C), there was a negligible effect of hepatic impairment on the total (bound+unbound) exposure of iptacopan. However, unbound iptacopan AUC inf increased by 48%, 58% and 271% in patients with mild, moderate, and severe hepatic impairment, respectively, compared to subjects with normal hepatic function. Drug Interaction Studies Based on a clinical drug interaction study in healthy volunteers, iptacopan exposure did not change to a clinically relevant degree when coadministered with clopidogrel (a moderate CYP2C8 inhibitor) or cyclosporine (a P-gp, BCRP, and OATP 1B1/1B3 inhibitor). The exposure of digoxin (a P-gp substrate) and rosuvastatin (an OATP substrate) did not change to a clinically relevant degree when coadministered with iptacopan.
