Official title

A Phase 1, Multi-center, Single-masked, Randomized, Placebo-controlled, Parallel-group Study to Investigate the Ophthalmologic Safety and Pharmacodynamics of 300mg Single Doses of Tafenoquine (SB 252263) in Adult Healthy Volunteers

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The study aims to provide evidence of retinal safety to support the use of tafenoquine as a potential single dose radical cure treatment for patients with Plasmodium vivax (P. vivax) malaria (i.e., co-administration of a schizonticidal drug with TQ). The study will be conducted as a single masked, randomized, placebo-controlled, parallel group design. It will assess retinal changes from baseline using spectral domain optical coherence tomography (OCT) and fundus auto fluorescence (FAF) at Month 3 (90 days) post-dose in adult healthy volunteers (participants). A placebo control group will be used to compare the results in the TQ group. Interim analysis will be conducted after completing 100 out of 300 participants in TQ group and 50 out of 150 participants in matched placebo.
