Trial Outcomes & Findings for Study of PRO 140 by Subcutaneous Administration in Adult Subjects With HIV -1 Infection (NCT NCT00642707)

NCT ID: NCT00642707

Last Updated: 2016-01-14

Results Overview

The primary end point was the maximum change from baseline in viral load following initiation of treatment, defined as HIV-1 copies/mL, measured by the Roche Amplicor HIV-1 Monitor UltraSensitive™ Test (lower limit of detection \[LLD\] = 48 copies/mL).

PRIMARY outcome

Timeframe: 59 days

Population: All randomized subjects who received one dose of study drug were considered intent-to-treat (ITT) subjects and were analyzed for efficacy.

The primary end point was the maximum change from baseline in viral load following initiation of treatment, defined as HIV-1 copies/mL, measured by the Roche Amplicor HIV-1 Monitor UltraSensitive™ Test (lower limit of detection \[LLD\] = 48 copies/mL).
