The Effects of HIV Protease Inhibitors in Severe Sepsis

Sepsis is the leading cause of death in critically ill patients in the United States. It develops in approximately 750,000 Americans annually, and more than 210,000 of them die. Despite improvements in supportive treatment, mortality has changed very little, and until recently, no sepsis-specific treatments were available. Protease inhibitors have seemed to have an immune benefit that extends beyond their ability to prevent HIV replication. T cells in those patients treated with protease inhibitors have reduced rates of death than in those patients not receiving therapy.

Condition Intervention Phase
Sepsis Drug: Nelfinavir Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: The Effects of HIV Protease Inhibitors in Severe Sepsis

Further study details as provided by Mayo Clinic:

Primary Outcome Measures:
  • Death from any cause at 28 days and 3 months
  • Daily APACHE II and III scores
  • Daily SOFA scores

Secondary Outcome Measures:
  • Change in CD4 and CD8 T-cell apoptosis, as determined by flow cytomerty, at the time of enrollment, on Day 4 of therapy, and upon completion of therapy.

Estimated Enrollment: 60
Study Start Date: June 2003
Study Completion Date: September 2005
Primary Completion Date: September 2005 (Final data collection date for primary outcome measure)
Detailed Description:
Our hypothesis is that protease inhibitor therapy will prevent apoptosis associated with sepsis, and this will be manifested as improved clinical outcome, as assessed by 28-day mortality, APACHE II and III, and SOFA scores. All patients enrolled in the study will receive the standard of care for sepsis at Mayo Clinic Rochester. Patients will receive 1250 mg of Nelfinavir/placebo twice each day for seven days with regularly scheduled blood draws (Days 0, 4, and 7).
