Pharmacokinetic and Safety Study of Travoprost 0.004% in Pediatric Glaucoma Patients

Overview

The purpose of this study was to assess the safety and describe the steady-state plasma pharmacokinetic (PK) profiles of Travoprost ophthalmic solution, 0.004% (new formulation) following a once daily administration for 7 days in pediatric glaucoma or ocular hypertension patients.

Clinical Trial Outcome Measures

Primary Measures

  • Maximum Observed Travoprost Free Acid Plasma Concentration (Cmax)
    • Time Frame: Day 7, Up to 80 minutes postdose
    • Travoprost free acid plasma concentrations at each collection time point (predose, 10, 20, 40, 80 minutes postdose) were quantitated using a high performance liquid chromatography/tandem mass spectrometry method (HPLC/MS/MS). Cmax was calculated for each participant with at least 1 quantifiable time point.
  • Time to Reach Cmax (Tmax)
    • Time Frame: Day 7, Up to 80 minutes postdose
    • Analyte plasma concentrations at each collection time point (predose, 10, 20, 40, 80 minutes postdose) were quantitated using a high performance liquid chromatography/tandem mass spectrometry method (HPLC/MS/MS). Tmax was calculated for each participant with at least 1 quantifiable time point.
  • Time to Last Measurable Concentration (Tlast)
    • Time Frame: Day 7, Up to 80 minutes postdose
    • Analyte plasma concentrations at each collection time point (predose, 10, 20, 40, 80 minutes postdose) were quantitated using a high performance liquid chromatography/tandem mass spectrometry method (HPLC/MS/MS). Tlast was calculated for each participant with at least 1 quantifiable time point.
  • Area Under the Analyte Plasma Concentration-time Curve to the Last Quantifiable Sampling Time Point [AUC(0-tlast)]
    • Time Frame: Day 7, Up to 80 minutes postdose
    • Analyte plasma concentrations at each collection time point (predose, 10, 20, 40, 80 minutes postdose) were quantitated using a high performance liquid chromatography/tandem mass spectrometry method (HPLC/MS/MS). AUC(0-tlast) was calculated for each participant with at least 2 quantifiable time points.
  • Area Under the Analyte Plasma Concentration-time Curve Over the Dosing Interval (Inf)[AUC(0-∞)]
    • Time Frame: Day 7, Up to 80 minutes postdose
    • Analyte plasma concentrations at each collection time point (predose, 10, 20, 40, 80 minutes postdose) were quantitated using a high performance liquid chromatography/tandem mass spectrometry method (HPLC/MS/MS). AUC(0-∞) was calculated for each participant with at least 3 quantifiable time points.
  • Half-life (t½)
    • Time Frame: Day 7, Up to 80 minutes postdose
    • Analyte plasma concentrations at each collection time point (predose, 10, 20, 40, 80 minutes postdose) were quantitated using a high performance liquid chromatography/tandem mass spectrometry method (HPLC/MS/MS). T½ was calculated for each participant with at least 3 quantifiable time points.

Participating in This Clinical Trial

Inclusion Criteria

  • Diagnosis of glaucoma or ocular hypertension in at least 1 eye. – Parent/legal guardian must provide informed consent, and children must agree to sign an approved assent form when applicable. – Must agree to comply with the requirements of the study and must be accompanied by a parent/guardian. – Other protocol-defined inclusion criteria may apply. Exclusion Criteria:

  • Females of childbearing potential that are currently pregnant, have a positive result on a pregnancy test at the Screening Visit, intend to become pregnant during the study period, are breast feeding, or are not using birth control measures. – One sighted eye or monocular, including patients who cannot be dosed in both eyes for any reason. – History of chronic, recurrent or severe inflammatory eye disease. – Ocular trauma requiring medical attention within the past 3 months prior to the Screening Visit. – Ocular infection or ocular inflammation within the past 30 days prior to the Screening Visit. – Clinically significant or progressive retinal disease such as retinal degeneration, diabetic retinopathy, or retinal detachment. – Other severe ocular pathology (including severe dry eye), that in the opinion of the Investigator, would preclude the administration of a topical prostaglandin analogue. – Intraocular surgery within the past 30 days prior to the Screening Visit. – Any abnormality preventing reliable tonometry. – Any other conditions including severe illness which would make the patient, in the opinion of the Investigator, unsuitable for the study. – Hypersensitivity to prostaglandin analogues or to any component of the study medications in the opinion of the Investigator. – Therapy with another investigational agent or device within 30 days prior to the Screening Visit. – Body weight < 5kg. – Other protocol-defined exclusion criteria may apply.
