Pharmaceutical group Glaxo Wellcome saw its shares move ahead 40p to pounds 19.80 as it received approval from the European Commission to market its Agenerase
protease inhibitor, used for HIV patients, in all 15 countries in the EU.
Vertex's first approved product is Agenerase
(amprenavir), an HIV protease inhibitor, which Vertex co-promotes with Glaxo Wellcome.
* Scores for these new drugs are preliminary, and these drugs do not appear in the original table.(2) [dagger] Lexiva (fosamprenavir) should penetrate CSF similarly to Agenerase
Luber, executive director of research at Tower ID Medical Associates, Los Angeles, noted that amprenavir (Agenerase
) is the only protease inhibitor currently approved by the Food and Drug Administration for once-daily dosing.

-- The Food and Drug Administration has approved Agenerase
for the treatment of HIV infection.
(amprenavir; formerly 141W94, VX - 478) is a new protease inhibitor drug from Vertex and Glaxo Wellcome in Phase III clinical trials.
Hoffman-LaRoche developed an "improved" version of saquinavir (Fortovase) and GlaxoSmithKline developed fosamprenavir (Lexiva) to replace amprenavir (Agenerase
After 24 weeks, the combination of Invirase, Agenerase
, and Norvir plus nucleoside reverse transcriptase inhibitors (NRTIs or "nukes") decreased viral load and increased T cell count.
* For certain advanced patients, a combination of amprenavir (Agenerase
) and lopinavir plus ritonavir (Kaletra), with some extra ritonavir (Norvir) added to overcome an interaction that would reduce the levels the other two drugs, appeared to work well.
