A Three-part Study to Determine the Safety, Tolerability and Pharmacokinetics of GSK1322322 in Healthy Volunteers and Healthy Male Japanese Subjects

• Status: Terminated
• Trial end date: 2013-10-18

Summary

The primary objectives of this study are to assess the safety, tolerability and pharmacokinetics of GSK1322322 following intravenous (IV) and oral administration. GSK1322322 shows broad spectrum antibacterial activity against pathogens involved in respiratory tract infections as well as methicillin-resistant S. Aureus (MRSA).

This study consists of three parts (Part A, Part B and Part C). The results from Part A of this study will enable use of large-scale, commercial tablets produced for administration to patients in pivotal clinical trials of GSK1322322. The results from Parts B and C will support enrolment of Japanese subjects in future clinical studies. Additionally, the results will support the dose selection for further clinical development of GSK1322322 in hospitalized patients with severe bacterial infections in Japan and other Asian populations.

In Part A, subjects will undergo screening, 4 treatment periods receiving single dose of each of: 1500 mg Initial, fit-for-purpose tablet (product code AP), 1500 mg Over granulated tablet (product code AR), and the 1500 mg and 2000 mg of intended commercial tablets (product code AU).

In Part B of the study subjects will undergo screening, and be randomized to receive 3 doses of GSK1322322 oral cohort (100 mg, 1500 mg and 2000 mg) or IV cohort (600 mg, 900 mg and 1200 mg) each in 3 treatment periods.

Part C will be a single-blind, placebo-controlled, repeat dose study of GSK1322322 in healthy Japanese male subjects. GSK1322322 will be administered (fasted) via IV for 4 days BID, followed by administration of GSK1322322 orally (fed) for 6 days BID. A follow-up evaluation will be conducted 7-10 days following last dose of for each subjects in each Part of the study.

Approximately 12 subjects will be enrolled in each part of the study such that approximately 8, 6, and 9 subjects complete dosing and critical assessments in part A,B, and C respectively.
