NCT02815566

Brief Summary

Design: Open-label randomised multicenter international strategic trial of older women on combination antiretroviral therapy (cART) containing tenofovir-emtricitabine (TDF/FTC) with HIV RNA suppression for \> 6 months to : 1. Immediate switch of TDF/FTC to tenofovir alafenamide-emtricitabine (TAF/FTC) while continuing the third antiretroviral agent.; 2. Delayed switch; with switch of TDF/FTC to TAF/FTC at 48 weeks while continuing the third agent. Follow up of all subjects to 96 weeks. Subject Population: The anticipated sample size is 128 HIV infected women aged 45-55 years (peri or early post menopause). . Primary endpoint: Percentage change from baseline bone mineral density (BMD) at the lumbar spine at weeks 48 and 96. Secondary Endpoints: BMD change at hip, trabecular bone score, estimated bone strength by high resolution peripheral quantitative computerized tomography (HR-pQCT), muscle quality, geriatric assessment; biomarkers of bone, immune activation and inflammation; HIV viral suppression; safety, lipid and renal function, cardiovascular risk scores at weeks 48 and 96. Expected Outcomes: To determine if a switch from TDF/FTC to TAF?FTC improves BMD to a degree correlating with a decreased risk of fragility fracture in aging HIV infected women. Secondary outcomes will assess bone strength using new imaging modalities, timing of switch, and renal health. This data will be used by health policy makers and providers to determine the proper use of TAF/FTC in the aging HIV population.

Outcome Measures

Primary Outcomes (1)

  • Percent Change in Bone Mineral Density From Baseline at the Lumbar Spine

    The outcome measures presented are descriptive as enrollment in the clinical trial did not reach the target number of subjects needed to achieve target power and was insufficient to produce statistically reliable results. There are limited results at the week 48 timepoint due to the COVID pandemic.

    Baseline, 48 weeks and 96 weeks

Secondary Outcomes (1)

  • % Change in Bone Mineral Density From Baseline at the Femoral Neck

    Baseline, 48 weeks and 96 weeks

Study Arms (2)

Immediate switch

EXPERIMENTAL

Open label tenofovir-alafenamide (25/10mg)-emtricitabine (200mg) tablet once daily by mouth for 96 weeks

Drug: tenofovir-alafenamide-emtricitabine

ACTIVE COMPARATOR

Open-label tenofovir (300mg)-emtricitabine (200mg) tablet once daily by mouth for 48 weeks followed by open label tenofovir-alafenamide (25/10mg)-emtricitabine (200mg) tablet once daily by mouth for an additional 48 weeks

Drug: tenofovir-emtricitabine

Eligibility Criteria

Age40 Years - 60 Years
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Biological female aged 40-60
  • Documented HIV-1 infection
  • Peri-menopausal ( as documented by history).
  • Signed Informed Consent Form and willing to comply with the protocol.
  • Receiving a cART regimen containing a ritonavir boosted PI (darunavir, atazanavir, lopinavir,) or an NNRTI (efavirenz, nevirapine or rilpivirine) or an integrase inhibitor (dolutegravir or raltegravir or elvitegravir) in combination with TDF-FTC for \> 24 weeks.
  • Stable viral suppression (plasma HIV-RNA\<50 copies/mL for \> 24 weeks). Single viral blip \<500/ml allowed if re-suppresses.
  • If of childbearing potential, is using effective birth control methods and is willing to continue during the trial.
  • Women will be assessed for vitamin D and calcium dietary intake; if inadequate for age, supplements will be recommended.

You may not qualify if:

  • HIV-2
  • High 10-year fracture risk at baseline ( \> 20%) based on country specific FRAX
  • Current treatment with active bone medications- bisphosphonates, denosumab, calcitonin, raloxifene, teriparatide, strontium
  • Current use of systemic steroids ( inhaled steroids permitted) or chemotherapeutic agents
  • Acute viral hepatitis
  • Chronic hepatitis C with liver transaminases \>5 x ULN or expected to require treatment for hepatitis C during the trial period.
  • Any investigational ARV within 30 days.
  • Dialysis or renal insufficiency (creatinine clearance \< 50ml/min)
  • History of decompensated liver disease (AST or ALT≥5x the upper limit of normal (ULN) or ALT ≥ 3 x ULN and bilirubin ≥ 1.5 x ULN with \> 35% direct bilirubin), or the presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or gastric varices.
  • Pregnant or breastfeeding
  • Screening blood result with any grade 3/4 toxicity according to Division of AIDS (DAIDS) grading scale, except: asymptomatic grade 3 amylase, creatinine phosphokinase, or lipid elevation.
  • Any condition (including illicit drug use or alcohol abuse) or lab results which, in the investigator's opinion, interfere with assessments or completion of the trial.

Limitations and Caveats

Enrollment was a challenge and did not reach the target subject number and was insufficient to produce statistically reliable results. This was primarily due to long delays in study start-up associated with contract negotiations. During the delays, most eligible participants switched to a TAF based regimen outside of the study. The COVID pandemic prevented enrollment of additional participants. The study was closed to futility on the recommendation of the DSMB
