Fabhalta (iptacopan)
The key clinical trials which demonstrated the effectiveness and safety of iptacopan were:
• A pivotal phase III study: a randomised, active-controlled study, comparing iptacopan monotherapy to anti-C5 treatment (C5 is a complement component) in paroxysmal nocturnal haemoglobinuria patients with residual anaemia despite prior anti-C5 therapy.
• A supportive Phase III study: a single arm, open-label study, evaluating iptacopan monotherapy in PNH patients who were naïve to complement inhibitor treatment.
These studies (and others) demonstrated the persistence of efficacy (and feasibility for long-term use) of iptacopan for up to 3 years.
This submission was evaluated under the standard prescription medicines registration process.

Capsule shell: Hard gelatin, red iron oxide (E 172), titanium dioxide (E 171), and yellow iron oxide (E 172).
Printing ink: Black iron oxide (E 172), concentrated ammonia solution (E 527), propylene glycol (E 1520), potassium hydroxide (E 525), and shellac (E 904).
The recommended dose is 200 mg taken orally twice daily.
Studies in animals have not shown evidence of an increased occurrence of fetal damage.
There are insufficient data on Fabhalta use in pregnant women to inform a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. There are risks to the mother and fetus associated with untreated PNH in pregnancy. Paroxysmal nocturnal haemoglobinuria in pregnancy is associated with adverse maternal outcomes, including worsening cytopenia, thrombotic events, infections, bleeding, miscarriages and increased maternal mortality, as well as adverse fetal outcomes, including fetal death and premature delivery. The use of Fabhalta in pregnant women or women planning to become pregnant may be considered following an assessment of the risks and benefits.
No malformations of other adverse effects on embryofetal development were observed in rats or rabbits with oral administration of iptacopan during the major period of organogenesis up to the highest doses tested (1000 mg/kg/day and 450 mg/kg/day in the respective species). These doses yield exposure to iptacopan 18-times higher in rats (based on unbound plasma AUC) and 8-times higher in rabbits (based on AUC for total drug) than in patients at the MRHD.
Fabhalta (iptacopan) has been approved for the treatment of adult patients with paroxysmal nocturnal haemoglobinuria.
Fabhalta is to be included in the Black Triangle Scheme. The PI and CMI for Fabhalta must include the black triangle symbol and mandatory accompanying text for five years. The Black Triangle Scheme identifies new prescription medicines with a black triangle on the medicine information documents. The black triangle is a visual reminder to encourage health practitioners and patients to report a problem or side effect associated with this medicine.
The Fabhalta EU-Risk Management Plan (RMP) ((version 1.1, dated 6 December 2023, data lock point 2 November 2022) with Australian Specific Annex (version 1.1, dated 22 February 2024), included with submission PM-2023-02564-1-6 and any subsequent revisions, as agreed with the TGA will be implemented in Australia. An obligatory component of risk management plans is routine pharmacovigilance which includes the submission of periodic safety update reports (PSURs).
