Peter,
I disagree with your first conclusion:
"If you start with any of the other PI's and become resistant (which might happen even if you maintain good viral suppression) you will likely also be resistant to Viracept."
-Ron Swanstrom's work did not include Viracept (nelfinavir).
Furthermore, Winters et al. presented early results of a combination of in vitro and in vivo studies (Florida meeting) where there is some evidence that:
-8 out of 9 sequinavir-treated patients do not have the 90 mutation, which would suggest resistance to nelfinavir.
-However, in vitro susceptibility testing showed that isolates from some sequinavir-treated patients already had reduced susceptibility to nelfinavir and/or indinavir prior to treatment with these inhibitors.
As I do not own any AGPH or MRK stock my perspective is probably different than most of the people tha post here. Nevertheless, my conclusions are mostly similar to yours and others in this discussion and I eagerly anticipate solid results about PIs.
(By the way, the results I quote were not from Agouron's or Merck's scientists but from researchers at Stanford.
