WHAT IDEFIRIX IS AND WHAT IT IS USED FOR
Idefirix contains the active substance imlifidase, which belongs to a
group of medicines called
immunosuppressants. It is given before your kidney transplantation to
prevent the immune system
(your body's defences) from rejecting the donated kidney.
Idefirix works by breaking down a type of antibody in the body called
immunoglobulin G (IgG),
which is involved in destroying 'foreign' or harmful substances.
Imlifidase is a protein from a bacterium called
_Streptococcus pyogenes._

CLINICAL PARTICULARS
4.1
THERAPEUTIC INDICATIONS
Idefirix is indicated for desensitisation treatment of highly
sensitised adult kidney transplant patients
with positive crossmatch against an available deceased donor. The use
of Idefirix should be reserved
for patients unlikely to be transplanted under the available kidney
allocation system including
prioritisation programmes for highly sensitised patients.
4.2
POSOLOGY AND METHOD OF ADMINISTRATION
Treatment should be prescribed and supervised by specialist physicians
experienced in the
management of immunosuppressive therapy and of sensitised renal
transplant patients.
Imlifidase is restricted to hospital use only.
Posology
The dose is based on patient body weight (kg). The recommended dose is
0.25 mg/kg administered as
a single dose preferably within 24 hours before transplantation. One
dose is adequate for crossmatch
conversion in the majority of patients but, if needed, a second dose
can be administered within
24 hours after the first dose.
After treatment with imlifidase, crossmatch conversion from positive
to negative should be confirmed
before transplantation (see section 4.4).
Premedication with corticosteroids and antihistamines should be given
to reduce the r
