Response from Dr. Sherer

This is a more promising era for people like you with a long history of treatment and multi-class resistance. It's not possible to give you a detailed answer, as I lack too much important information, and complex cases like yours do not lend themselves well to this type of forum. Still, I will make some comments for you and your doctor to consider.
From your story, it appears that your doctor has chosen the best possible regimen from the options available to you, i.e. raltegravir + etravirine + Truvada.
One suggestion that you might talk about with your doctor is the possibility that you remain on darunavir/RTV and enfuvirtide (ENF) now, and, if possible, you could consider removing ENF in future if and when you are able to achieve full control with this new regimen, and if the skin reactions were becoming a burden. Even in patients who have been on enfuvirtide for a while, it appears that the drug makes a contribution to virologic control. Similarly, depending on the results of the most recent resistance test, there might be some residual contribution of darunavir.
The overall results from the raltegravir phase III clinical trials in heavily treatment experienced patients like you were that 2/3 of patients achieved viral load suppression below 50 copies/ml for 48 weeks. Even better outcomes were seen if the at least one of the other drugs was active, and better still if two or more of those drugs were active. Patients who did best were those in whom either enfuvirtide or darunavir were used for the first time - which does not apply to you. Even in patients who had previously been on enfuvirtide, it added about a 10% benefit.
Your best options at present are with the most recently approved drugs, and it sounds like your physician is making sound decisions with these options.
Other options that may be useful to you in future - but some 2-3 years away - are CXCR4 inhibitors, another integrase inhibitor, other new NNRTIs and NRTIs, and some other new targets like a novel maturation inhibitor.
I urge you to take these observations and talk to your doctor about them.
