A combination comprising

• 4-[[4-[[4-(2-cyanoethenyl)-2,6-dimethylphenyl]-amino]-2-pyrimidinyl]-amino]-benzonitrile, or a stereoisomeric form thereof or a pharmaceutically acceptable salt thereof;
• a nucleoside reverse transcriptase inhibitor;
• and
• a nucleotide reverse transcriptase inhibitor;
• wherein the 4-[[4-[[4-(2-cyanoethenyl)-2,6-dimethylphenyl]-amino]-2-pyrimidinyl]-amino]-benzonitrile, the nucleotide reverse transcriptase inhibitor, and the nucleoside reverse transcriptase inhibitor are therapeutically effective HIV inhibitors at a dose that can be administered once daily.
