To Brooke: There are MANY reasons to switch from Genvoya to Biktarvy (smaller pill size, fewer drug interactions, no food requirement, higher barrier to resistance), but interestingly, CD4 count and viral load response are not different between the two. Both include integrase inhibitors, so viral load response is fast and essentially the same. CD4 response is essentially the same for any regimen that suppresses viral load. (The most notable exception is with efavirenz-based regimens such as Atripla, which tend to have blunted CD4 responses compared to other regimens.) It's great that you've had a good response, but it may have nothing to do with the switch, and you shouldn't be alarmed if your CD4 count fluctuates in either direction. Such fluctuations are rarely due to the ART regimen.

I'm an HIV Peer Educator at University Health in Kansas City, MO I just switched from Genvoya to Biktarvy after a year of watching patients blood labs and how fast they change. My CD4 has not been over 400 since my diagnosis in 2010. I'd been on Genvoya for almost 10 years and had no interest in changing my meds until I saw results in the lab changes of newly diagnosed patients and the drastic changes in viral loads and CD4's. Ambivalence in patients comes from their lack of education as well as them not feeling any different on ART VRS or not. I believe seeing results will help this patient and others get on board with changing meds.

Jeffrey,
Thank you for your reply, I greatly appreciate it. Great insight. I have seen this patient a couple of times and he expresses interest in a switch but is quite ambivalent about making a change, it may take time to continue developing rapport and trust with him.
Thanks again!
Ryan

Hi Ryan
from someone who has been providing HIV care since 1989 out of residency, I would say an important piece with a NEW patient is to go gingerly with them when it comes to medication change (ART) - especially when they have been doing well (VL < 20/ CD4 -700) on their current regimen and their prior doctor did not (likely) recommend a change. Biktarvy from a renal perspective makes sense and hopefully something he would understand if explained carefully. Many of my older long-term patients who used to come in monthly and then q3 or q6 months with simplified safer regimens - also started requesting yearly visits. Although our Ryan White Clinic has a 6-month visit policy - I generally agreed to yearly visits for some patients - with the caveat being they would get "safety/ screening labs) at a 6 month interval but would not need an office visit. The other challenge with aging HIV patients is then addressing co-morbidities which can be difficult with only once visit a year. "Dance" with them -- and once they have gained trust and confidence you should be able to do what is clinically best for them.

Hello,
I have a patient who recently transferred care to me who has been on Genvoya for many years and has been doing well with respect to control of HIV, always virally suppressed and great CD4 count (most recent CD4 >700). Patient does have CKD3a. We were recently discussing switching from Genvoya to Biktarvy as an option as patient may be interested, however patient is also very hesitant to come in for visits more frequently than annually for wellness visits. I am open to switching the patient to Biktarvy, however I am concerned about his willingness to attend closer follow up after the switch to assess for adherence and obtain follow up labs. Curious if others have thoughts? I have discussed with the patient given ongoing adequate control of HIV, there may not be indication/need to make a regimen change.
Thanks!
Ryan
