6.1Clinical 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 trials of another drug and may not reflect the rates observed in practice. Paroxysmal Nocturnal Hemoglobinuria (PNH) The data described below reflects the exposure in adults with PNH who received FABHALTA (n = 62) or anti-C5 treatment (US-approved and non-US-approved eculizumab product or US-approved and non-US-approved ravulizumab product, n = 35) in APPLY-PNH [NCT04558918] and adults who received FABHALTA (n = 40) in APPOINT-PNH [NCT04820530] at the recommended dosing regimen for 24 weeks.
In APPLY-PNH, serious adverse reactions were reported in 2 (3%) patients with PNH receiving FABHALTA. Serious adverse reactions included pyelonephritis, urinary tract infection and COVID-19. In APPOINT-PNH, serious adverse reactions were reported in 2 (5%) patients with PNH receiving FABHALTA. Serious adverse reactions included COVID-19 and bacterial pneumonia. The most common adverse reactions (≥ 10%) with FABHALTA were headache, nasopharyngitis, diarrhea, abdominal pain, bacterial infection, viral infection, nausea, and rash.
Table 1 describes the adverse reactions that occurred in > 5% of patients treated with FABHALTA in the APPLY-PNH or APPOINT-PNH studies. Table 1: Adverse Reactions Reported in > 5% of Patients Treated with FABHALTA in APPLY-PNH or APPOINT-PNH Studies (24-Week Treatment Period) a Includes similar terms. b Nasopharyngitis contains: rhinitis allergic, upper respiratory tract infection, pharyngitis, rhinitis. c Bacterial infection contains: pyelonephritis, urinary tract infection, bronchitis bacterial, bronchitis haemophilus, cholecystitis, folliculitis, cellulitis, arthritis bacterial, sepsis, klebsiella infection, staphylococcal infection, Pseudomonas infection, hordeolum, pneumonia bacterial. d Viral infection contains: COVID-19, herpes zoster, oral herpes, nasal herpes, influenza A virus test positive, influenza. e Lipid disorder contains: dyslipidemia, blood cholesterol increased, low density lipoprotein increased, hypercholesterolemia, blood triglycerides increased, hyperlipidemia. f Rash contains: dermatitis allergic, acne, erythema multiforme, rash maculo-papular, rash erythematous.

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. Table 2 describes the adverse reactions that occurred in ≥ 3 % of patients treated with FABHALTA and were ≥ 2% higher in frequency than placebo.
All of these adverse reactions were mild or moderate in severity. Table 2: Adverse Reactions Reported in ≥ 3% of Adult Patients with IgAN (eGFR ≥ 20 mL /min/1.73 m 2 ) Treated with FABHALTA and ≥ 2% Higher in Frequency Than Placebo in APPLAUSE-IgAN 1 Includes similar terms.

No new adverse reactions were identified during the 6-month placebo-controlled period of APPEAR-C3G, in which 38 patients were treated with FABHALTA and 36 patients were treated with placebo. The most common adverse reactions that occurred in ≥ 10% of patients treated with FABHALTA and were ≥ 5% higher in frequency than placebo were nasopharyngitis (11% in FABHALTA, 3% placebo) and viral infections (29% in FABHALTA, 22% placebo), mainly respiratory infections.
One patient (3%) on FABHALTA and none on placebo had a serious adverse reaction of pneumonia and bacteremia secondary to an encapsulated organism ( S. pneumoniae ).
