A5241 - The Optimized Treatment that Includes or Omits NRTIs (OPTIONS) Trial: A Randomized Strategy
Study for HIV-1-Infected Treatment-Experienced Subjects Using the cPSS to Select an Effective Regimen
(All study information from A5241 Participant Information Sheet.)
Eligible candidates:
Study Objective:
This study will look at whether newer anti-HIV drugs are safe and effective in a group of HIV- infected persons
whose current HIV medicines are not working. The study will also test whether using a specific type of medicines
called nucleoside reverse transcriptase inhibitors (NRTIs) are needed to treat HIV in persons failing their
current medicines. Finally this study will test whether a medicine resistance test score called the cPSS is able
to predict which drugs will work best in people whose virus is resistant to specific HIV medications.
Study Scheme:
Part One (up to 60 days): You will remain on your current anti-HIV regimen. You will have blood drawn and
a group of study physicians will review your resistance testing, your cPSS score and the type of virus that you
have, as well as your previous medication history. The study physicians will recommend one or more study drug
combinations that will give a cPSS test score above 2 to you and your primary doctor. Some of the possible
combinations include different types of pills; other combinations include pills and a medicine called enfuvirtide
which must be injected. If there are two or more combinations that may work for you, your primary doctor and you
will pick one. If the study physicians and your primary doctor can not choose a study drug combination that will
give a cPSS score above 2, you might enter part two of the study if there are still enough spaces left in this
group. Otherwise, if there is only one combination that may work, you will be expected to take that combination.
The study physicians will also recommend a combination of NRTIs based on the results of the resistance test.
Again, if there is more than one possible NRTIs combination choice, your primary doctor and you will be able to
pick one you might take. Once you and your study physician choose the study drug combination and the NRTI
combination you want to start, you will be randomized (chosen as if by a flip of a coin). The randomization will
determine whether or not you will take the NRTIs that you selected along with the other study medicines.
Part Two (48 weeks): In part two of the study, you will receive your medicines and return to the clinic
at least 8 times for a blood draw and health check up. During this time, you will have testing of your HIV viral
load (HIV level) and CD4 cell counts, and will have tests to make sure the new drugs are safe. If the new drugs
do not work to make your viral load low enough, you will have another resistance test done as part of the study;
results of these tests will be given to your primary doctor.
