: Menopause is a high-risk period for osteoporosis, which may be exacerbated by HIV and/or antiretroviral therapy (ART). Our goal was to study the impact of switching from tenofovir disoproxil fumarate (TDF) to tenofovir alafenamide (TAF) on bone mineral density (BMD) in peri- and early postmenopausal women living with HIV. This is a randomized international multicenter study of an early versus delayed (48-week) switch. BMD was measured by dual energy X-ray absorptiometry scan. Thirty-four women were enrolled: 19 in the immediate and 15 in the delayed switch arm from September 2017 to April 2019; 30 completed the 96-week protocol. The study closed for futility during the COVID-19 pandemic. The median (intraquartile range [IQR]) age was 51 years (47, 53), with a median (IQR) of 16.5 years (14, 23) since HIV diagnosis, median (IQR) 14 years (11, 20) of ART, and mean 8.6 years TDF. At enrollment, TDF was used in combination with a boosted protease inhibitor (n = 7), a non-nucleoside reverse transcriptase inhibitor (n = 13), an integrase inhibitor (n = 11), or more than one ART class (n = 3). The median (95% confidence interval [CI]) percentage change in BMD at the lumbar spine from 0 to 48 weeks in the immediate switch group was 1.97% (-1.15 to 5.49) compared with a median (95% CI) decrease of 2.32% (-5.11 to 0.19) in the delayed arm. The median (95% CI) percentage change in BMD from 0 to 96 weeks was 2.33% (0-4.51) in the immediate arm compared with 0.70% (-3.19 to 2.47) in the delayed arm.

Abstract
: Menopause is a high-risk period for osteoporosis, which may be exacerbated by HIV and/or antiretroviral therapy (ART). Our goal was to study the impact of switching from tenofovir disoproxil fumarate (TDF) to tenofovir alafenamide (TAF) on bone mineral density (BMD) in peri- and early postmenopausal women living with HIV. This is a randomized international multicenter study of an early versus delayed (48-week) switch. BMD was measured by dual energy X-ray absorptiometry scan. Thirty-four women were enrolled: 19 in the immediate and 15 in the delayed switch arm from September 2017 to April 2019; 30 completed the 96-week protocol. The study closed for futility during the COVID-19 pandemic. The median (intraquartile range [IQR]) age was 51 years (47, 53), with a median (IQR) of 16.5 years (14, 23) since HIV diagnosis, median (IQR) 14 years (11, 20) of ART, and mean 8.6 years TDF. At enrollment, TDF was used in combination with a boosted protease inhibitor (n = 7), a non-nucleoside reverse transcriptase inhibitor (n = 13), an integrase inhibitor (n = 11), or more than one ART class (n = 3). The median (95% confidence interval [CI]) percentage change in BMD at the lumbar spine from 0 to 48 weeks in the immediate switch group was 1.97% (-1.15 to 5.49) compared with a median (95% CI) decrease of 2.32% (-5.11 to 0.19) in the delayed arm. The median (95% CI) percentage change in BMD from 0 to 96 weeks was 2.33% (0-4.51) in the immediate arm compared with 0.70% (-3.19 to 2.47) in the delayed arm. We demonstrated a trend to increased BMD at the lumbar spine after a switch from TDF to TAF in peri- and early postmenopausal women living with HIV.
