ABSTRACT
PURPOSE:
To evaluate the systemic pharmacokinetics (PKs) of travoprost 0.004% preserved with Polyquad® (TRAVATAN®) in pediatric patients with glaucoma or ocular hypertension.METHODS:
This was a phase 1, open-label, multicenter clinical study of patients aged ≥2 months to <18 years. Patients received daily administration of travoprost 0.004% preserved with Polyquad in both eyes for 7 days. Plasma samples were collected 30 min before the final dose and at 10, 20, 40, and 80 min postdose. The main outcome measure was maximum concentration of travoprost free acid in plasma (Cmax).RESULTS:
Included in the PK analysis were 24 patients (average age 9.6 ± 4.9 years). At least 1 sample with quantifiable levels of travoprost free acid was collected for 11 patients. The mean Cmax was 0.0471 ± 0.0105 ng/mL for patients aged 2 months to <3 years; 0.0258 ± 0.0128 ng/mL for ages 3 to <12 years; and 0.0109 ± 0.0005 ng/mL for ages 12 to <18 years. Travoprost was undetectable in samples collected predose from pediatric patients. Treatment-related adverse events (AEs) included hyperemia, eye pain, and eye pruritus (n = 1 each). There were no discontinuations or drug-related serious AEs.CONCLUSIONS:
Travoprost free acid concentration in plasma was low in pediatric patients, detectable in only 11 of 24 patients. There was no accumulation of travoprost over the course of treatment. No clear relationship was observed between age/body surface area and Cmax. No increased risk was identified for the use of travoprost 0.004% preserved with Polyquad in patients <18 years of age.Palavras-chave
