  • 1.  Simplification of regimen with documented resistance

    Posted 06-26-2023 15:49

    Hello,

    I would to solicit some thoughts on simplifying my pt's regimen.  She really wants to be on a single tablet regimen:

    58 y/o female diagnosed with HIV in 2006, noted for some low level viremia but generally controlled.  Reports she was previously on Trizivir.  She is currently on Descovy, Prezcobix and Tivicay (since 2017) and suppressed.  She is noted for NRTI mutations of M41L, M184V and T215Y and NNRTI A98G.  Other medical problems are hypertriglyceridemia and obesity, otherwise healthy, and she is on no other meds other than her ARVs.

    I remember the presentation about the NADIA study from one of the conferences which seem to fit my patient (please anyone correct me if I am wrong).  From the NADIA study in pts with NRTI resistance, looks like I can either put her on a Truvada+DTG or Truvada+DRV/r regimen.  In looking at the study there were 4 failures in the DTG with resistance versus none in the DRV/r.  Due to her hypertriglyceridemia, which maybe coming from the PI as she reports generally a healthy diet, I'm considering putting her on Truvada+DTG.  However, I'm also concerned about the failure with resistance in the DTG arm. 

    Any thoughts of a single tablet regimen for the patient?  She really wants to be on a single pill.

    Thank you everyone!

    I have attached a copy of her only resistance test on file, the results from Standford HIV databse and VL results.

    Hi Jenny,

    I think BIC/FTC/TAF (Biktarvy) would be a good option for this patient. I have similar patients to this and they tend to do very well on Biktarvy.

    Hi Jenny,

    I can't read the type on the resistance tests, but you are mentioning two TAMs and the M184V.  Tenofovir should have full, or almost full, activity in this case.  She is currently on the equivalent of Symtuza/Tivicay.  If she really wants an STR, I'd go with Symtuza, as long as she promises to be compliant.   She would be on two active agents with a high barrier to resistance. You are really just dropping the Tivicay.  I'd just deal with the TGs (she is already on a boosted PI - how are her TGs being managed?).  The other option would be Biktarvy, which should also work fine.  Weight gain could be an issue, but she is already on a regimen containing TAF and a second generation INSTI.  Thanks!

    Dear Dr Tan,
    Based on the data that you present, the best and only STR (in my opinion) for her is DRV/cobi/TAF/FTC (Symtuza). There is good data demonstrating continued viral suppression with switch to DRV/c/TAF /FTC with known M184V and a limited number of TAMs (M41L, T215Y). I would not feel confident in using an InSTI STR (Biktarvy, Triumeq or Dovato).
    I would attribute her previous VL >20, but <200 cos/mL as due to assay variation and not truly LLV.

    In my opinion, if she requires a single tablet regimen to simplify her treatment, Biktavvy, a single tablet regimen, may be suitable based on her resistance pattern. However, if you are concerned that changing her regimen might lead to treatment failure, you can consider using dual therapy with Dolutegravir plus Cobicistat-boosted Darunavir to simplify her treatment without evidence of previous resistance. Decreasing the number of pills may improve adherence and convenience for her.
