ISRCTN ISRCTN58987964
DOI 10.1186/ISRCTN58987964
ClinicalTrials.gov identifier
EudraCT number
Public title An open randomised trial to evaluate the activity and tolerability of combinations of reverse transcriptase and protease inhibitors, including induction therapy, in individuals with Human Immunodeficiency Virus-1 (HIV-1) infection and CD4 cell counts greater than 25 x 10 to the power of 6 per litre
Scientific title
Acronym The FORTE trial
Serial number at source G9719167 (extension, ProCom trial)
Study hypothesis To evaluate, in patients starting anti-HIV therapy, the activity over at least 48 weeks of two regimens in terms of effects on plasma HIV RNA, CD4 cell counts, viral resistance, progression of HIV disease and survival, and safety and tolerability.

Patient information material
Target number of participants 100
Interventions 1. Didanosine (ddI), Stavudine (d4T), Nevirapine (NVP) plus Nelfinavir (NFV) for at least 24 weeks, then ddI, d4T and NVP as maintenance therapy
2. Continuous ddI, d4T plus NVP

Note: third arm with continuous ddI, d4T, NVP plus NFV deleted November 2000.
Primary outcome measure(s) Virological failure defined as failure to achieve plasma HIV RNA less than 50 copies per millilitre during the first 24 weeks or, having achieved such a level of suppression, subsequent rebound of plasma HIV RNA above 400 copies per millilitre.
Secondary outcome measure(s) Not provided at time of registration
