Treatment-experienced HIV-infected patients with documented genotypic or phenotypic resistance to at least one ART drug within three drug classes OR Treatment-experienced HIV-infected patients with documented genotypic or phenotypic resistance to at least one ART drug within two drug classes and have limited treatment options.

Resistant to 3 drug classes or resistant to two drug classes with limited treatment options. Why would someone resistant to just two drug classes have limited options? Maybe most people they recruited were in the resistant to three drug classes category. Anyway, dropping it to two drug classes opens up the population size, possible substantially.
