The Safety and Effectiveness of Isoprinosine in Patients With Weakened Immune Systems and Lymph Node Disease

This study has been completed.
Information provided by:
NIH AIDS Clinical Trials Information Service Identifier:
First received: November 2, 1999
Last updated: June 23, 2005
Last verified: June 1989

The objective of this Phase III, randomized, double-blind, placebo-controlled study in patients with immunologic deficiency is to determine the effect of Isoprinosine in producing an immuno-restorative response within the study observation period (including the 2-month period following cessation of the 28 days of treatment), measured by one or more of the following immunological parameters:

  • Increase in natural killer (NK) cell activity.
  • Increase in total T-cells (OKT-11).
  • Increases in absolute number and percentage of T-helper cells (OKT-4).

Condition Intervention
Lymphatic Disease HIV Infections Drug: Inosine pranobex

Study Type: Interventional
Study Design: Masking: Double
Primary Purpose: Treatment
Official Title: A Multi-Center Randomized Double-Blind Placebo-Controlled Study to Investigate the Effect of Isoprinosine in Immunodepressed Patients With Uncomplicated Generalized Lymphadenopathy
