Treatment initiation: Treatment with ritlecitinib should not be initiated in patients with an absolute lymphocyte count (ALC) <0.5 x 10³/mm³ or a platelet count <100 x 10³/mm³ (see Precautions).
Treatment interruption or discontinuation: If a patient develops a serious infection or opportunistic infection, ritlecitinib should be interrupted until the infection is controlled (see Precautions).
Interruption or discontinuation of treatment may be needed for management of haematologic abnormalities as described in Table 2.
If treatment interruption is needed, the risk of significant loss of regrown scalp hair after a temporary treatment interruption for less than 6 weeks is low.
Missed doses: If a dose is missed, patients should be advised to take the dose as soon as possible unless it is less than 8 hours before the next dose, in which case the patient should not take the missed dose. Thereafter, dosing should be resumed at the regular scheduled time.
Special populations: Renal impairment: No dose adjustment is required in patients with mild, moderate, or severe renal impairment (see Pharmacology: Pharmacokinetics under Actions).
Ritlecitinib has not been studied in patients with end-stage renal disease (ESRD) or in patients with renal transplants and is therefore not recommended for use in these patients.
Hepatic impairment: No dose adjustment is required in patients with mild (Child Pugh A) or moderate (Child Pugh B) hepatic impairment (see Pharmacology: Pharmacokinetics under Actions). Ritlecitinib is contraindicated in patients with severe (Child Pugh C) hepatic impairment (see Contraindications).
Elderly: No dose adjustment is required for patients ≥65 years of age. There are limited data in patients ≥65 years of age.
Paediatric population: No dose adjustment is required for adolescents 12 to <18 years of age.
The safety and efficacy of LITFULO in children under 12 years of age have not yet been established. No data are available.
Method of administration: Oral use.
LITFULO is to be taken once daily with or without food.
Capsules should be swallowed whole and should not be crushed, split or chewed, because these methods of administration have not been studied in clinical trials.
