Brief Summary:
This study is a 3-arm pilot, randomized, double-blinded, placebo-controlled study of low-dose naltrexone and gabapentin versus placebo among HIV-positive persons with heavy alcohol use and chronic pain to provide estimates of their effects on 1) pain; 2) inflammation; and 3) measures of HIV control. Participants will be followed for 12 weeks. Assessments of study outcomes will be compared at week 8 (end of treatment phase).

Condition or disease Intervention/treatment Phase
Chronic Pain Alcohol Use, Unspecified HIV Infections Drug: Low-dose naltrexone Drug: Gabapentin Drug: Placebo Phase 2

Detailed Description:
Pain is a common co-morbidity for HIV-positive patients.Prevalence studies suggest that, on average, half of all HIV-positive persons suffer pain. Chronic pain can lead to heavy alcohol use among HIV-positive persons, which may in turn be a barrier to treatment/control of HIV and contribute to spread of HIV. Thus there is an urgent need to address pain among persons with HIV. It is timely and relevant to conduct research on gabapentin, as it has emerged as one of the most commonly prescribed non-opioid medications for pain despite the fact that gabapentin is only FDA approved for "post-herpetic neuralgia" and the literature to support its use for generalized chronic pain is limited. And yet, gabapentin has demonstrated benefits for treatment of alcohol use disorder, and therefore, like naltrexone, it could have a specific role for treating patients with chronic pain and unhealthy alcohol use. This study is a 3-arm pilot, randomized, double-blinded, placebo-controlled study of low-dose naltrexone and gabapentin vs. placebo among HIV-positive persons with heavy alcohol use and chronic pain to provide estimates of their effects on 1) pain (both self-reported and experimental/cold pressor test; 2) inflammation (i.e., levels of inflammatory cytokines IL-6 and TNF-α); and 3) measures of HIV control (CD4 count and viral load).

Arm Intervention/treatment
Active Comparator: Low-dose naltrexone
Participants randomized to this group will receive low dose naltrexone (4.5 mg) for 8 weeks.
Drug: Low-dose naltrexone
4.5 mg of low dose naltrexone taken once daily for 8 weeks. Participants in this group will also receive two matching placebo capsules to be taken twice daily with the active medication in weeks 1-3 and 8. In weeks 3-7, participants will take take 2 capsules three times per day (5 placebos, 1 active study medication) to match the the dosing regimen of the gabapentin arm. In week 7, participants will take two matching placebo capsules to be taken twice daily with the active medication (three capsules per day).

Active Comparator: Gabapentin
Participants randomized to this group will receive a dose of 900 mg gabapentin daily (300 mg tid), in week 2 the dose will be titrated up to 1800 mg daily (600 mg tid). In week 3, participants in the gabapentin arm will be titrated to 2700 mg daily (600 mg+300 mg tid) and will remain on the dose until week 7, when they will be tapered back down to 900 mg daily (days 1-3: 600 mg tid, days 4-7: 300 mg tid).
Drug: Gabapentin
Dose will begin at 900 mg daily (300 mg tid), in week 2 the dose will be titrated up to 1800 mg daily (600 mg tid). In week 3, the dose will be titrated to 2700 mg daily (600 mg+300 mg tid) until week 7, and then tapered back down to 900 mg daily (days 1-3: 600 mg tid, days 4-7: 300 mg tid). Gabapentin will only be titrated up as tolerated by the participant.

Placebo Comparator: Placebo
Participants will receive a placebo to be taken three times daily for 8 weeks.
Drug: Placebo
Capsule taken three times a day for 8 weeks in weeks 1-3 and 8. In week 3, dosing will change to 2 capsules three times per day until week 7. In week 7, participants will take three placebo capsules per day.




Primary Outcome Measures :
  1. Change in past week pain severity [ Time Frame: Endpoint at 8-weeks ]
    Change in past week pain severity (score 0-10) from baseline to week 8. Pain severity will be measured using the Brief Pain Inventory

  2. Change in past week pain interference [ Time Frame: Endpoint at 8-weeks ]
    Change in past week pain interference (score 0-10) from baseline to week 8. Pain interference will be measured using the Brief Pain Inventory


Secondary Outcome Measures :
  1. Change in Biomarkers IL-6 and TNF-α between baseline and week 8 [ Time Frame: Endpoint at 8-weeks ]
    Levels of these pro-inflammatory markers will be measured on blood samples collected using commercially available enzyme-linked immunosorbent assay kits (R&D Systems).

  2. Change in cold pain tolerance between baseline and week 8 [ Time Frame: Endpoint at 8-weeks ]
    This will be measured using the cold-pressor test; briefly it is the number of seconds a participant can keep hand submerged in cold water bath

  3. Change in percentage of past month heavy drinking days between baseline and week 8 [ Time Frame: Endpoint at 8-weeks ]
    Timeline Follow Back method will be used to assess drinks per day in the past 4 weeks. Using a calendar, participants provide retrospective estimates of their daily drinking over the past 30 days from the interview date.

  4. Change in measures of HIV control between baseline and week 8 [ Time Frame: Endpoint at 8-weeks ]
    CD4 cell counts and HIV viral loads will be measured on participants
