- Intent to have surgery during the study period (12 months)
- Hepatitis C treatments (e.g., interferon, ribavirin, protease inhibitors) within the past 6 months
- Cirrhosis or hepatic impairment (e.g., Child-Pugh class B or C).
- Seizure disorder
- Previous/current CNS space occupying lesion (e.g., Toxoplasmosis, mTB) with persistent abnormalities on CNS imaging after completion of treatment.
- Surgical or invasive procedure anticipated during study period.
- Invasive cancer in the prior year or receiving cancer treatment (not including carcinoma-in-situ or basal cell cancer of the skin)
- Rheumatologic or inflammatory disease, systemic in nature (e.g., systemic lupus erythematosus, rheumatoid arthritis, vasculitis, sarcoidosis, Crohn's disease)
- Assessment by the clinical investigator that enrollment into the study could entail excess risk to the participant, beyond what is intended or expected.

5. Study Description
Brief Summary
The purpose of this study is to evaluate the effects of pharmacologic FXa inhibition (via edoxaban 30 mg daily) on inflammation, as reflected in plasma Interleukin-6 levels.
Detailed Description
We hypothesize that increased generation of activated factor X (FXa) contributes to a systemic elevation in pro-inflammatory cytokine levels (e.g. IL-6) among HIV positive patients. This occurs, in part, via FXa activation of protease activated receptor 2 (PAR-2) on monocytes and tissue macrophages, which perpetuates innate inflammation. We will test our hypothesis with an oral antagonist to FXa (edoxaban), and quantify the immunologic effects of PAR-2 inhibition on systemic inflammation and monocyte activation.
The potential benefits of pharmacologic inhibition of FXa will be studied among HIV positive participants receiving ART with suppressed HIV viral load and a D-dimer >100 ng/mL. The study design is a cross-over placebo controlled randomized trial of edoxaban 30mg daily versus matched placebo (n=40 total participants). After screening and baseline visits, participants will be randomized to the sequence of drug administration (i.e., edoxaban vs. placebo). After randomization, participants will start study medication #1 and follow-up for visits at months 1, 2, 3 and 4. They will then stop study medication for 3 months, return for visits at months 7 and 8 (analogous to screening and baseline, respectively), then start study medication #2 and follow-up for visits at months 9, 10, 11, and 12.
The treatment effect (i.e., changes from pre-treatment levels) over 4 months will be assessed in measures of inflammation, immune activation, and coagulation. For comparisons with placebo, each participant will then serve as his or her own control in this cross-over design.
