Safety and Efficacy Study in Subjects With Diabetic Neuropathic Pain - Full Text View

Sponsored by:	Abbott
Information provided by:	Abbott
ClinicalTrials.gov Identifier:	NCT00507936

Purpose

This study will compare the efficacy and the safety of ABT-894 (1mg, 2mg or 4mg capsules) administered BID to placebo in the treatment of DNP. Another treatment arm will be Duloxetine 60mg administered once daily (QD).

Approximately 275 subjects will be enrolled into the study at approximately 50 sites in both the United States and Europe.

The study will be divided into the following periods: Screening/Washout (21 days) followed by a Baseline Visit, an 8-week Treatment Period and a 1-week Follow-up Visit.

Primary Outcome Measures:

Efficacy of each ABT-894 dose (1 mg, 2 mg, or 4 mg BID) versus placebo in the treatment of pain due to DNP [ Time Frame: Change from baseline to final 24-hour average pain score ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Proportions of treatment responders; subjects who complete treatment period with 30% improvement [ Time Frame: From Baseline to final 24-hour average pain score ] [ Designated as safety issue: No ]
Mean of 24-hour worst pain severity, average of night pain, and average of morning pain measured by the 11-point Likert scale and from subject's daily diary [ Time Frame: Weekly through treatment phase ] [ Designated as safety issue: No ]
Brief Pain Inventory (BPI) (short form) including Pain Severity [ Time Frame: At each visit from Baseline to Week 8 visit ] [ Designated as safety issue: No ]
Clinician Global Impression: Severity (CGI-S) and Patient Global Impression: Change (PGI-C) [ Time Frame: At each visit from Baseline to Week 8 visit ] [ Designated as safety issue: No ]

Enrollment:	280
Study Start Date:	July 2007
Primary Completion Date:	October 2008 (Final data collection date for primary outcome measure)
