Infectious Disease

Statistics Collaborative, Inc. (SCI) has considerable experience in infectious disease, both in adults and in children. From our founding in 1990, we’ve worked on diseases caused by bacteria, viruses, retroviruses, and parasites. Some of the trials have investigated antibacterials or antivirals, while others have studied vaccines. Still others have studied methodologies for early detection of disease.

Dr. Wittes has served on Food and Drug Administration (FDA) Advisory Committees that have dealt with setting margins for non-inferiority trials in infectious disease. She has also been an ad hoc member of an Advisory Committee for a treatment for influenza.

In addition to our work with industry and with FDA, we collaborate with nonprofit groups that develop vaccines or treatments for malaria, tuberculosis, and HIV/AIDS.

Examples of SCI’s work in infectious disease:

  • Hepatitis C: SCI provided statistical reporting and coordination for a Data Monitoring Committee (DMC) for a Phase 3 study of a novel treatment formulation.
  • Vancomycin-resistant enterococci (VRE) infection: SCI reviewed the available scientific literature for roughly 40 studies to determine patient risk factors and aspects of therapy that might predispose patients to nosocomial VRE colonization and blood stream infections.
  • Sepsis: SCI has supported several DMCs monitoring Phase 2 and 3 studies in different populations with sepsis. Some trials studied adults at high and moderate risk; other trials studied children with sepsis or meningococcemia. The studies have used a variety of investigational therapies as well as common standard-of-care. Because of the severity of the disease and the toxicity of many of the therapies, SCI has assisted in developing DMC futility and safety stopping guidelines.
  • Seasonal and pandemic influenza: SCI has been involved with the clinical development of FluMist®, an inhaled influenza vaccine, from Phase 1 through Phase 4 trials. We have assisted with protocol development, with analysis, and with the writing of the clinical study reports (CSRs) for the FDA submission.
