List of Sites for ACTG 398, ACTG 400, and ICC study #006

Studies 398 and 400 will explore a number of questions including the influence of baseline genotypic and phenotypic protease inhibitor and RT inhibitor resistance profiles. As well, the studies will evaluate the genotypic and phenotypic resistance profiles to the study drugs that emerge on treatment. There will be several important substudies including a pharmacokinetics study to determine the PK relationships between the study drugs, and substudies evaluating immunological responses. Investigators will try to determine to the extent possible the relationship between drug exposure (as measured by a combination of PK and compliance) to drugs and the degree of duration of response and the emergence of resistance. As well, a PK relationship profile will be conducted for ritonavir+saquinavir when coadministered with efavirenz.

ICC study #006 will offer 5 different open-label treatment regimens. Three regimens will be for individuals who’ve failed protease inhibitors but are naive to NNRTIs, and two regimens with simplified dosing regimens for treatment naive persons. The study will be open label. Originally, the study was supposed to begin in February but its been delayed. The first few regimens are expected to begin enrollment in early June. The study will enroll 25 persons in each regimen at 7 different sites. The 3 regimens for protease failures are expected to be:

• adefovir+efavirenz+141W94+1592U89

• MKC-442+delavirdine+ddI+d4T

• MKC-442+nevirapine+ddI+d4T

MKC-442 is a NNRTI in early development which has shown a 1.30 log reduction in viral load in a 15 day study. This trial is the first to study the combination of two NNRTIs.

The two simplified dosing regimens are for protease inhibitor naive individuals:

• indinavir+nelfinavir+efavirenz (both indinavir and nelfinavir will be taken twice daily

• a once a day 4-drug regimen of adefovir+3TC+ddI+efavirenz

ACTG Sites. It is optional to a site whether or not they want to pick up an ACTG study. So, you have to check with your local site to determine if they offer these studies. If you are interested it may be important to contact the site quickly for information because enrollment could fill up quickly.
