New HIV Treatment Guidelines, and the End of an Era
April 8, 2015
Paul E. Sax, M.D., is director of the HIV Program and Division of Infectious Diseases at Brigham and Women's Hospital in Boston.
The new Department of Health and Human Services (DHHS) HIV treatment guidelines are out, and thanks to skillful direction by Alice Pau, it's as usual a must-read document -- all 288 pages, of course!
There are several major changes, so a good place to start is the all-important "What's New in the Guidelines" summary page. Some of the biggest modifications come in the "What to Start" section:
- There's now a more focused list of "Recommended regimens" -- it's down to just 5. Specifically, TDF/FTC plus DTG or EVG/c or RAL (that's 3), ABC/3TC/DTG (4), and TDF/FTC plus DRV/r (5).
- The regimens that are limited to patients with low HIV RNA are now classified either as "Alternative" -- TDF/FTC/RPV -- or "Other" (ABC/3TC plus EFV, ABC/3TC plus ATV/r).
- TDF/FTC plus ATV/r is now an "Alternative" regimen, largely due to the results of ACTG 5257.
- TDF/FTC/EFV is now an "Alternative" regimen, largely due to issues of tolerability.
With the caveat that as a member of the Guidelines panel, I can only give you my personal perspective (not that of the committee), here are a few comments on this last one -- the demotion of efavirenz from "Recommended" to "Alternative" -- which seems to me a pretty big deal.
First the good stuff about EFV, which was approved by the FDA way back in 1998:
- In clinical trials, efavirenz has been better or as good virologically than all its comparators for years and years. I still remember the shock when we learned that EFV creamed indinavir -- a potent protease inhibitor, who would have predicted that? -- and subsequently it won or tied in numerous head-to-head studies. That success continued until the drug was compared to integrase inhibitors (in particular dolutegravir), but note that rates of virologic failure were still just as low with EFV even in this comparison. And is there any agent that so consistently does well in patients with high baseline HIV RNA and/or low CD4?
- Efavirenz has such a long half life that regimens with the drug are remarkably forgiving, even if people forget to take it every day. It's so forgiving, in fact, that studies suggest you can do fine taking it only 5 days a week, or at a reduced daily dose. Not that we recommend these strategies, but still -- we all have patients on EFV-based regimens who admit that they skip it periodically (usually because of side effects, but that's a different story), yet they maintain virologic control.
- Although no HIV treatment is cheap, TDF/FTC/EFV is less expensive than most of the other initial regimens we use today.
- Efavirenz (with TDF/FTC or TDF/3TC) is the default initial treatment globally, where it is widely available as a single pill taken once a day. That counts for a lot -- obviously the vast majority of people with HIV in the world don't live here.
So what's the issue? Why then is it now an "Alternative" rather than a "Recommended" option? In my opinion, it comes down to progress we've made in improving side effects. Many choices are available now that are simply easier for patients -- and clinicians, who can skip the time on pre-treatment education and management of tricky side effects. Specifically:
- All the clinical trials comparing EFV with integrase-based options demonstrate significantly lower rates of central nervous system (CNS) side effects with the latter. As already noted, in the head-to-head study against dolutegravir, drug discontinuations due to adverse events led to a superior result for DTG. The same thing happened when EFV was compared to RPV – in the low viral load stratum, RPV was superior because it was better tolerated.
- Virtually everyone who starts EFV gets some sort of CNS side effect of varying severity in the first week or two. Not a good idea to start the day (or even a week) before a big presentation, or travel, or some other major life event. In most patients, these CNS side effects diminish rapidly over the first few weeks of therapy. However, a minority still have some residual weirdness going on long term -- dizziness, abnormal dreams, morning grogginess. Some learn to live with it and are fine, but others don't realize how off they've been feeling until they stop the drug. (Brief aside -- what's up with the small fraction of patients who choose to take EFV during the day? That always perplexed me.)
- More serious CNS side effects can rarely occur, in particular depression. In this retrospective analysis of four randomized clinical trials, patients randomized to EFV-based regimens had a more than two-fold increased risk of suicide or suicidal ideation compared with those not receiving EFV. And while the absolute risk was overall low, this is a severe enough adverse effect that one should be very cautious about using the drug in anyone with a history of depression. Although observational cohort and claims data have not shown this association, remember that this is a tricky thing to find in such data, and that in clinical practice we avoid prescribing EFV to patients with psychiatric disease.
- Every ID/HIV doctor has had patients who just can't take this drug, and it's not from depression. OK, anecdote time -- here are a few of mine: The guy who drives for a living who knew immediately he wasn't as alert on the road taking EFV. The person whose dreams were so vivid that they were essentially indistinguishable from hallucinations (and not pleasant ones). The high-functioning scientist who simply couldn't concentrate at work. The person (actually a few) with severe rash and fevers. Of course some of the vivid dream stories were pretty funny -- my favorite was someone who dreamt that her kitchen had been extensively renovated, including specific selections of cabinets and appliances. Imagine her disappointment when she came downstairs to find the scruffy old kitchen unchanged!
Yes, I still have patients on EFV-based treatment who are doing great, and they don't want to switch -- that's fine, no reason to do so. But the bottom line is that I haven't prescribed TDF/FTC/EFV to a patient starting HIV therapy in nearly three years. Too many other good options out there now.
Hey, progress is a good thing!
I did this poll before -- now let's try it again, a year and a half later:
I still frequently use efavirenz-based regimens as initial therapy.
- True still the gold standard.
- False plenty of better options out there now.

64 year old white male started atripla November 2013...the dreams were too vividly grotesque and horrifying, and an empty tummy for two hours was difficult. So, meds are taken at 5:00-5:30 am in work days with breakfast at 7:30. On weekends, meds are taken 6:30-8:00, after sleeping late, with breakfast two hours later, although I suspect that waiting one hour to eat would be sufficient. Occasionally there is a flattening and dulling of mood with an awareness that it could be biochemical and caused by the med. However, that mild depressed feeling is minimal compared to the severely depressed thoughts and feelings that arise when pondering one's self-inflicted compromised health and longevity...

I have only taken 2 drugs (1) Sustiva (2) ATIPLA. Though I have neuropathy likely rom these Meds..it has worked so well that I hesitate changing. People don't like change when all looks well with Blood Reports done now twice a year (Sero converted 1998)

I moved from Atripla to Clompera as soon as was able. The wacky dreams never stopped, and Complera has fewer "do this to take that" issues.
My lament is that the article is so very clinical. In fact, though in teaser pointing to this piece, the word Atripla doesn't seem to appear. So much else if over my head.
I'm highly educated, and trust my medical saviors immensely. But couldn't you perhaps summarize the 288 pages with descriptions (or at least brand names) for the lay person instead of maintaining the high-level Gunning-Fog Index?

I took EFV for 3.5 years. I had significant side effects, most of which included depression and morning grogginess. I switched to RPV (Atripla to Complera) and I feel back to normal. EFV was a wicked drug, in my opinion. I battled (and sometimes conquered depression) but I simply had a very, very difficult time adapting.

I`ve been on Atripla for about 10 years now. I`ve been on a couple of medication holidays...one was for 3 months. Bloodwork taken at 2 months was still undetectable viral load. At 4 months the viral load became detectable but at a low level.
Now it is becoming clear that someone on Atripla with undectectable viral load and 1035 cd4(like myself)is virtually incapable of transmiting(infecting)another person with HIV by sexual transmition. But...what about intravenous drug use and shared needles. Besides not being a good idea on a number of levels, would or could HIV transmition also be prevented under those circumstances? Would that be the ultimate litmus test of the effectiveness of ART of Truvada &EFV? I would appreciate a personal response even though this is a hypothetical question. I am not an intravenous drug user and if I was I would never share a needle.

False. Haven't initiated anyone on efavirenz for many years. The king is dead; long live the (new) kings.
