This study has been withdrawn prior to enrollment.
World Health Organization
Information provided by (Responsible Party):
Pfizer Identifier:
First received: December 17, 2009
Last updated: March 27, 2012
Last verified: March 2012
The purpose of this study is to measure the amount of moxidectin in subjects' blood and to measure safety. This study will enroll 36 children aged 4 to 11 years (>=12 kg) with or without Onchocerca volvulus (O volvulus) infection. O volvulus is the nematode, or roundworm, that causes Onchocerciasis, also known as river blindness. Each subject will receive a single dose of 4 mg moxidectin (orally administered) and will be followed inpatient from screening through day 13 and as outpatients through month 6. The study will take place at a single research center.

Condition Intervention Phase
Onchocerciasis Drug: moxidectin Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Single-Center, Open-Label, Single-Dose Study To Assess The Pharmacokinetics, Safety, And Tolerability Of Moxidectin In Subjects Aged 4 To 11 Years ( >=12 kg) With Or Without Onchocerca Volvulus Infection

Secondary Outcome Measures:
  • The safety and tolerability of a single dose of 4 mg moxidectin in subjects as measured by physical examinations, laboratory tests, vital signs and ECG findings [ Time Frame: 6 months ]
