Indications

HARLIKU™ is indicated for the reduction of urine homogentisic acid (HGA) in adult patients with alkaptonuria (AKU).


Warnings and Precautions

Ocular Symptoms and Hyperkeratotic Plaques Due to Elevated Plasma Tyrosine Level
Ocular signs and symptoms including keratitis, corneal opacities, corneal irritation, corneal ulcers, conjunctivitis, eye pain, and photophobia, have been reported in patients.

  • Perform slit-lamp examination prior to treatment and regularly thereafter. Reexamine patients if symptoms develop or tyrosine levels are > 500 micromole/L. Assess plasma tyrosine levels in patients with an abrupt change in neurological status.
  • Perform a clinical laboratory assessment, including plasma tyrosine levels, in patients with an abrupt change in neurological status.

Leukopenia and Severe Thrombocytopenia
In clinical trials, patients with hereditary tyrosinemia type 1 (HT-1) treated with another oral formulation of nitisinone and dietary restriction developed reversible leukopenia (3%), thrombocytopenia (3%), or both (1.5%). No patients developed infections or bleeding as a result of the episodes of leukopenia and thrombocytopenia. Monitor platelet and white blood cell counts during HARLIKU therapy.


Adverse Reactions

The most common adverse reactions (≥1%) reported in patients with AKU taking nitisinone in clinical trials are elevated tyrosine levels, thrombocytopenia and keratitis.


Drug Interactions

  • Nitisinone is a moderate CYP2C9 inhibitor and a weak CYP2E1 inducer. Potential clinical impact of Harliku administration with CYP2C9 substrates. Reduce the dosage of the co-administered drugs metabolized by CYP2C9 by half. Additional dosage adjustments may be needed.
  • Nitisinone is an inhibitor of OAT1/OAT3. Potential clinical impact of administration with OAT1/OAT3 substrates. Patients should be monitored for potential adverse reactions.

Use in Specific Populations

Pregnancy: Limited available data with nitisinone use in pregnant women are not sufficient to determine a drug-associated risk of adverse developmental outcomes. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.

Lactation: The developmental and health benefits of breastfeeding should be considered against the mother’s clinical need for HARLIKU, along with potential adverse effects on the breastfed infant from HARLIKU or from the underlying maternal condition.

Pediatric Use: The safety and effectiveness of HARLIKU have not been established in pediatric patients with AKU.

Geriatric Use: Insufficient data from clinical studies of HARLIKU to determine if patients ≥ 65 years of age respond differently. Elderly patients should be cautious reflecting any decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
