Detailní popis
Study Design:
This is an observational, open-label, non-randomised, single centre, 48-week study to explore the utility of a novel scanning platform exploring bone turnover during an immediate or deferred (for 48 weeks) switch from Eviplera® to Odefsey® in HIV-1 infected men aged 40 years or older, and stable on Eviplera®.
Participants:
HIV-1-infected males, aged ≥40 years, on Eviplera® >24 weeks, with plasma HIV RNA (pVL) <50cp/mL and without any known history of osteoporosis.
Groups to be Compared: 1. HIV-1-infected males aged ≥40, stable on Eviplera® (rilpivirine (RPV)/emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF)) and remaining on EvipleraÒ for 48 weeks on study; 2. HIV-1-infected males aged ≥40 years, switched to Odefsey® (RPV/FTC/tenofovir alafenamide (TAF)) at study enrollment.
Study Hypothesis: We hypothesis that there will be ongoing subclinical loss of bone at the hip and lumbar spine as measured by 18F-fluoride-PET/CT in those remaining of Eviplera®, and in those switching to Odefsey® there will be reversal of some of this subclinical loss at 24 and 48 weeks post switch.
Primary Outcome Measure(s):To determine the change in regional bone formation at the hip and lumbar spine as measured by 18F-fluoride-PET/CT at 24 weeks post switch from Eviplera® to Odefsey®.
Secondary Outcome Measure(s): 1. Change in regional bone formation at the hip and lumbar spine as measured by 18F-fluoride-PET/CT at 48 weeks post switch from Eviplera® to Odefsey®; 2. Assess safety and tolerability of switching to Odefsey®; 3. To compare DXA changes at the hip and lumbar spine to those detected on 18F-fluoride-PET/CT; 4. Measure changes in plasma/serum bone biomarkers over 24 and 48 weeks; 5. To measure the changes in FRAX® score at week 48.

Change in regional bone formation at the hip and lumbar spine as measured by 18F-PET/CT at 24 weeks.

Regions of interest will be applied to various regions within the hip including but are not limited to the femoral neck, intertrochanteric region, trochanter and total proximal femur.
Further regions of interest will be applied to each vertebral body, skull, pelvis and femoral shaft using the static scan for the calculation of standardised uptake values (SUV).

Regions of interest will be applied to including but not limited to the femoral neck, intertrochanteric region, total hip, each lumbar vertebral body, and upper femoral shaft for the calculation of Ki which reflects regional bone perfusion and bone turnover and will be compared to results obtained Dual-energy x-ray absorptiometry (DXA) scans will be performed at baseline (Visit 1b), weeks 24 (Visit 2b) and 48 (Visit 3b) to evaluate the change in areal bone mineral density (BMD) (in g/cm2) in response to treatment at the lumbar spine (L1-L4), total hip, femoral neck and whole body using standard protocols.

The changes in bone biomarkers over 24 and 48 weeks with changes in 18F-PET/CT;
Časové okno: 24 and 48 weeks
|
Regions of interest will be applied to including but not limited to the femoral neck, intertrochanteric region, total hip, each lumbar vertebral body, and upper femoral shaft for the calculation of Ki which reflects regional bone perfusion and bone turnover, with changes in bone biomarkers.
The bone markers to be analysed include, but are not limited to, procollagen Type I N terminal propeptide (PINP), and cross-linked C telopeptides of Type I collagen (CTX).
