Information added to 'the 'Liver problems', 'Infection' and 'Abnormal clotting of blood in small blood vessels (thrombotic microangiopathy' sections of the "Warning and Precautions".

Liver failure added as a possible side effect

Section 4.2:

• Pre-treatment laboratory testing updated to include albumin, prothrombin time, partial thromboplastin time (PTT) and international normalised ratio (INR) in the liver function tests
• Include recommendation that patients are clinically stable in their overall health status prior to infusion
• Liver function should be monitored before treatment and regularly for at least 3 months after infusion. Promptly assess patients with worsening liver function tests and/or signs or symptoms of acute illness.
• Patients with positive serology for hepatitis B or hepatitis C have not been studied in clinical studies with onasemnogene abeparvovec.

Section 4.4

Following information added to ‘Hepatotoxicity’:

• Fatal cases of acute liver failure have been reported in patients treated with onasemnogene abeparvovec.
• Promptly assess patients with worsening liver function tests and/or signs or symptoms of acute illness.
• If patients do not respond adequately to corticosteroids, consult a pediatric gastroenterologist or hepatologist and consider adjustment of the corticosteroid regimen.
• AST/ALT/total bilirubin should be assessed weekly for the first month after onasemnogene abeparvovec infusion and during the entire corticosteroid taper period
• Corticosteroids should not be tapered until liver function tests become unremarkable (normal clinical examination, total bilirubin, and ALT and AST levels below 2 × ULN).

Following information added to ‘Thrombotic microangiopathy’ (TMA)

• Cases generally occurred within the first two weeks after onasemnogene abeparvovec infusion. TMA is an acute and life-threatening condition, which is characterised by thrombocytopenia and microangiopathic haemolytic anaemia. Fatal outcomes have been reported.
• In case of thrombocytopenia, further evaluation including diagnostic testing for haemolytic anaemia and renal dysfunction should be undertaken promptly.

Following information added to ‘Systemic immune response’ (‘Immunomodulatory regimen’ renamed)

• Due to the increased risk of serious systemic immune response, it is recommended that patients are clinically stable in their overall health status (e.g. hydration and nutritional status, absence of infection) prior to onasemnogene abeparvovec infusion
• Patients with infection were excluded from participation in clinical trials with onasemnogene abeparvovec.
• Increased vigilance in the prevention, monitoring, and management of infection is recommended before and after onasemnogene abeparvovec infusion.

Section 4.8:

• Fatal cases of liver failure added to table of adverse reactions
• Post-marketing cases with transient decrease in platelet count to levels <25 x 10⁹/L within two weeks of administration have been reported (see section 4.4).
