Long-term effectiveness and safety of upadacitinib for Japanese patients with moderate-to-severe atopic dermatitis: a real-world clinical study.

BACKGROUND: Previous clinical trials presented efficacy and safety of Janus kinase 1 inhibitor upadacitinib through 52 weeks for moderate-to-severe atopic dermatitis (AD). OBJECTIVES: To assess the effectiveness and safety of upadacitinib through 48 weeks in real-world clinical practice for Japanese AD patients (aged ≥12 years). METHODS: This retrospective study included 287 patients with moderate-to severe AD treated with 15 mg (n = 216) or 30 mg (n = 71) of upadacitinib daily. Effectiveness was assessed using eczema area severity index (EASI) scores, atopic dermatitis control tool (ADCT), peak pruritus-numerical rating scale (PP-NRS), and investigator's global assessment (IGA). Safety was evaluated through the incidence of treatment-emergent adverse events. RESULTS: From baseline, EASI, ADCT, PP-NRS, and IGA rapidly reduced at week 4, and the reduction was maintained until week 48 of treatment with upadacitinib at both doses. Achievement rates of EASI 75, EASI 90, and EASI 100 at week 48 were 63.5, 30.2, and 7.9 in 15 mg group, and 77.4, 54.8, and 3.2% in 30 mg group, respectively. Acne and herpes zoster were frequent, but no serious adverse events occurred. CONCLUSIONS: Upadacitinib was therapeutically effective and tolerable for moderate-to-severe AD through 48 weeks in real-world clinical practice.

Prevalence of overweight and obesity among adolescents living with HIV after dolutegravir - based antiretroviral therapy start in Kampala, Uganda.

BACKGROUND: Dolutegravir (DTG)-based antiretroviral therapy (ART) is currently the preferred first-line treatment for persons living with HIV (PLHIV) including children and adolescents in many low- and middle-income countries including Uganda. However, there are concerns about excessive weight gain associated with DTG especially in adults. There remains paucity of current information on weight-related outcomes among adolescents on DTG. We determined the prevalence of excessive weight gain and associated factors among adolescents living with HIV (ALHIV) receiving DTG-based ART in Kampala, Uganda. METHODS: Cross-sectional study involving ALHIV aged 10-19 years on DTG-based ART for at least one year were recruited from public health facilities in Kampala between February and May 2022. Excessive weight gain was defined as becoming overweight or obese per body mass index (BMI) norms while on DTG-based ART for at least one year. Demographic, clinical and laboratory data were collected using interviewer-administered questionnaires and data extracted from medical records. At enrolment, blood pressure and anthropometry were measured and blood was drawn for blood glucose and lipid profile. Data was summarised using descriptive statistics and logistic regression was performed to determine the associated factors. RESULTS: We enrolled 165 ALHIV with a median age of 14 years (IQR 12-16). Eighty (48.5%) were female. The median duration on ART and DTG was 8 years (IQR 7-11) and 2 years (IQR 1-3) respectively. At DTG initiation, the majority of participants (152/165, 92.1%) were ART-experienced, and had normal BMI (160/165, 97%). Overall, 12/165 (7.3%) adolescents (95% CI: 4.2-12.4) had excessive weight gain. No factors were significantly associated with excessive weight gain after DTG start in ALHIV. However, all ALHIV with excessive weight gain were females. CONCLUSION: Our study found a prevalence of 7.3% of overweight and obesity in ALHIV after initiating DTG. We did not find any factor significantly associated with excessive weight gain in ALHIV on DTG. Nonetheless, we recommend ongoing routine monitoring of anthropometry and metabolic markers in ALHIV as DTG use increases globally, to determine the exact magnitude of excessive weight gain and to identify those at risk of becoming overweight or obese while taking the medication.

Pharmacokinetics and Safety of Lurbinectedin Administrated with Itraconazole in Cancer Patients: A Drug-Drug Interaction Study.

This open-label, two-part, phase Ib drug-drug interaction study investigated whether the pharmacokinetic (PK) and safety profiles of lurbinectedin (LRB), a marine-derived drug, are affected by co-administration of itraconazole (ITZ), a strong CYP3A4 inhibitor, in adult patients with advanced solid tumors. In Part A, three patients were sequentially assigned to Sequence 1 (LRB 0.8 mg/m2, 1-h intravenous [IV] + ITZ 200 mg/day oral in Cycle 1 [C1] and LRB alone 3.2 mg/m2, 1 h, IV in Cycle 2 [C2]). In Part B, 11 patients were randomized (1:1) to receive either Sequence 1 (LRB at 0.9 mg/m2 + ITZ in C1 and LRB alone in C2) or Sequence 2 (LRB alone in C1 and LRB + ITZ in C2). Eleven patients were evaluable for PK analysis: three in Part A and eight in Part B (four per sequence). The systemic total exposure of LRB increased with ITZ co-administration: 15% for Cmax, area under the curve (AUC) 2.4-fold for AUC0-t and 2.7-fold for AUC0-∞. Co-administration with ITZ produced statistically significant modifications in the unbound plasma LRB PK parameters. The LRB safety profile was consistent with the toxicities described in previous studies. Co-administration with multiple doses of ITZ significantly altered LRB systemic exposure. Hence, to avoid LRB overexposure when co-administered with strong CYP3A4 inhibitors, an LRB dose reduction proportional to CL reduction should be applied.

Pharmacokinetics and safety of coformulated bictegravir, emtricitabine, and tenofovir alafenamide in children aged 2 years and older with virologically suppressed HIV: a phase 2/3, open-label, single-arm study.

BACKGROUND: Coformulated bictegravir, emtricitabine, and tenofovir alafenamide is a single-tablet regimen and was efficacious and well tolerated in children and adolescents with HIV (aged 6 years to <18 years) in a 48-week phase 2/3 trial. In this study, we report data from children aged at least 2 years and weighing 14 kg to less than 25 kg. METHODS: We conducted this open-label, multicentre, multicohort, single-arm study in South Africa, Thailand, Uganda, and the USA. Participants were virologically suppressed children with HIV, aged at least 2 years, weighing 14 kg to less than 25 kg. Participants received bictegravir (30 mg), emtricitabine (120 mg), and tenofovir alafenamide (15 mg) once daily, switching to bictegravir (50 mg), emtricitabine (200 mg), and tenofovir alafenamide (25 mg) upon attaining a bodyweight of at least 25 kg. The study included pharmacokinetic evaluation at week 2 to confirm the dose of coformulated bictegravir, emtricitabine, and tenofovir alafenamide for this weight band by comparing with previous adult data. Primary outcomes were bictegravir area under the curve over the dosing interval (AUCtau) and concentration at the end of the dosing interval (Ctau) at week 2, and incidence of treatment-emergent adverse events and laboratory abnormalities until the end of week 24 in all participants who received at least one dose of bictegravir, emtricitabine, and tenofovir alafenamide. This study is registered with ClinicalTrials.gov, NCT02881320. FINDINGS: Overall, 22 participants were screened (from Nov 14, 2018, to Jan 11, 2020), completed treatment with bictegravir, emtricitabine, and tenofovir alafenamide (until week 48), and entered an extension phase. The geometric least squares mean (GLSM) ratio for AUCtau for bictegravir was 7·6% higher than adults (GLSM ratio 107·6%, 90% CI 96·7-119·7); Ctau was 34·6% lower than adults (65·4%, 49·1-87·2). Both parameters were within the target exposure range previously found in adults, children, or both". Grade 3-4 laboratory abnormalities occurred in four (18%) participants by the end week 24 and six (27%) by the end of week 48. Drug-related adverse events occurred in three participants (14%) by the end of week 24 and week 48; none were severe. No Grade 3-4 adverse events, serious adverse events, or adverse events leading to discontinuation occurred by the end of week 24 and week 48. INTERPRETATION: Data support the use of single-tablet coformulated bictegravir (30 mg), emtricitabine (120 mg), and tenofovir alafenamide (15 mg) for treatment of HIV in children aged at least 2 years and weighing 14 kg to less than 25 kg.

Efficacy, safety, and tolerability of dolutegravir-based ART regimen in Durban, South Africa: a cohort study.

BACKGROUND: Dolutegravir is an integrase strand transfer inhibitor that has been recommended for use in first-line antiretroviral regimens by the World Health Organisation and is currently being rolled out globally. There has been safety concerns with dolutegravir which has caused concern about its use in the general population. Dolutegravir first-line regimens have been used in South Africa since early 2020. Therefore, the aim of the present study was to assess the efficacy, safety, and tolerability of first-line dolutegravir-based antiretrovirals amongst adults living with HIV in Durban, South Africa. METHODS: This was a mixed-methods study, which comprised a cross-sectional survey and longitudinal retrospective follow-up of medical records. The study was conducted between October 2020 and January 2022. Data were described using descriptive and summary statistics. Bivariate logistic regression was applied to socio-demographic and clinical variables and crude odds ratios with a 95% confidence interval was calculated. Pearson chi-square tests, paired sample T-tests, and cross-tabulations were performed on selected variables. RESULTS: A total of 461 participants were enrolled in the study. There was a significant change in immunological outcomes (p < 0.001) after dolutegravir initiation. Furthermore, an assessment of laboratory parameters showed that there was a significant decrease in cholesterol (p < 0.001) and increase in creatinine (p < 0.001) levels. Increased weight was shown by 60.7% of the participants but was not associated with age, gender, CD4 counts, and previous antiretroviral usage. The study found that 43.6% of the participants experienced at least one side-effect. A total of 21.6% and 23.2% of the participants experienced neuropsychiatric and central nervous system side-effects, respectively. In the bivariate analyses, only gender was shown to be associated with side-effects, and only 1.7% of the participants discontinued the study due to side-effects. CONCLUSION: Our results suggest that dolutegravir is effective, safe, and well tolerated in the study population.

Efficacy and safety of switching to dolutegravir/lamivudine in virologically suppressed people with HIV-1 aged ≥ 50 years: week 48 pooled results from the TANGO and SALSA studies.

BACKGROUND: As the population of people with HIV ages, concerns over managing age-related comorbidities, polypharmacy, immune recovery, and drug-drug interactions while maintaining viral suppression have arisen. We present pooled TANGO and SALSA efficacy and safety results dichotomized by age (< 50 and ≥ 50 years). METHODS: Week 48 data from the open-label phase 3 TANGO and SALSA trials evaluating switch to once-daily dolutegravir/lamivudine (DTG/3TC) fixed-dose combination vs continuing current antiretroviral regimen (CAR) were pooled. Proportions of participants with HIV-1 RNA ≥ 50 and < 50 copies/mL (Snapshot, intention-to-treat exposed) and safety were analyzed by age category. Adjusted mean change from baseline in CD4 + cell count was assessed using mixed-models repeated-measures analysis. RESULTS: Of 1234 participants, 80% of whom were male, 29% were aged ≥ 50 years. Among those aged ≥ 50 years, 1/177 (< 1%) DTG/3TC participant and 3/187 (2%) CAR participants had HIV-1 RNA ≥ 50 copies/mL at 48 weeks; proportions with HIV-1 RNA < 50 copies/mL were high in both treatment groups (≥ 92%), consistent with overall efficacy and similar to observations in participants aged < 50 years (≥ 93%). Regardless of age category, CD4 + cell count increased or was maintained from baseline with DTG/3TC. Change from baseline in CD4 + /CD8 + ratio was similar across age groups and between treatment groups. One CAR participant aged < 50 years had confirmed virologic withdrawal, but no resistance was detected. In the DTG/3TC group, incidence of adverse events (AEs) was similar across age groups. Proportions of AEs leading to withdrawal were low and comparable between age groups. Although drug-related AEs were generally low, across age groups, drug-related AEs were more frequent in participants who switched to DTG/3TC compared with those who continued CAR. While few serious AEs were observed in both treatment groups, more were reported in participants aged ≥ 50 years vs < 50 years. CONCLUSIONS: Among individuals with HIV-1, switching to DTG/3TC maintained high rates of virologic suppression and demonstrated a favorable safety profile, including in those aged ≥ 50 years despite higher prevalence of concomitant medication use and comorbidities.

Determinants of early change in serum creatinine after initiation of dolutegravir-based antiretroviral therapy in South Africa.

AIMS: Dolutegravir increases serum creatinine by inhibiting its renal tubular secretion and elimination. We investigated determinants of early changes in serum creatinine in a southern African cohort starting first-line dolutegravir-based antiretroviral therapy (ART). METHODS: We conducted a secondary analysis of data from participants in a randomized controlled trial of dolutegravir, emtricitabine and tenofovir disoproxil fumarate (TDF) or tenofovir alafenamide fumarate (TAF) (ADVANCE, NCT03122262). We assessed clinical, pharmacokinetic and genetic factors associated with change in serum creatinine from baseline to Week 4 using linear regression models adjusted for age, sex, baseline serum creatinine, HIV-1 RNA concentration, CD4 T-cell count, total body weight and co-trimoxazole use. RESULTS: We included 689 participants, of whom 470 had pharmacokinetic data and 315 had genetic data. Mean change in serum creatinine was 11.3 (SD 9.9) µmol.L-1. Factors that were positively associated with change in serum creatinine at Week 4 were increased log dolutegravir area under the 24-h concentration-time curve (change in creatinine coefficient [ß] = 2.78 µmol.L-1 [95% confidence interval (CI) 0.54, 5.01]), TDF use (ß = 2.30 [0.53, 4.06]), male sex (ß = 5.20 [2.92, 7.48]), baseline serum creatinine (ß = -0.22 [-0.31, -0.12]) and UGT1A1 rs929596 A→G polymorphism with a dominant model (ß = -2.33 [-4.49, -0.17]). The latter did not withstand correction for multiple testing. CONCLUSIONS: Multiple clinical and pharmacokinetic factors were associated with early change in serum creatinine in individuals initiating dolutegravir-based ART. UGT1A1 polymorphisms may play a role, but further research on genetic determinants is needed.

Body weight and blood pressure changes on dolutegravir-, efavirenz- or atazanavir-based antiretroviral therapy in Zimbabwe: a longitudinal study.

INTRODUCTION: Dolutegravir (DTG) is widely used for antiretroviral therapy (ART). We compared weight and blood pressure trends and examined the association between high blood pressure and weight gain among people living with HIV (PLHIV) switching to or starting DTG-based, efavirenz (EFV)-based and ritonavir-boosted atazanavir (ATV/r)-based ART in Zimbabwe. METHODS: PLHIV aged 18 years or older who started or switched to DTG, EFV or ATV/r-based ART between January 2004 and June 2022 at Newlands Clinic in Harare, Zimbabwe, were eligible. Weight was measured at all visits (Seca floor scales); blood pressure only at clinician-led visits (Omron M2 sphygmomanometer). We used Bayesian additive models to estimate trends in weight gain and the proportion with high blood pressure (systolic >140 mmHg or diastolic >90 mmHg) in the first 2 years after starting or switching the regimen. Finally, we examined whether trends in the proportion with high blood pressure were related to weight change. RESULTS: We analysed 99,969 weight and 35,449 blood pressure records from 9487 adults (DTG: 4593; EFV: 3599; ATV/r: 1295). At 24 months after starting or switching to DTG, estimated median weight gains were 4.54 kg (90% credibility interval 3.88-5.28 kg) in women and 3.71 kg (3.07-4.45 kg) in men, around twice that observed for ATV/r and over four-times the gain observed for EFV. Prevalence of high blood pressure among PLHIV receiving DTG-based ART increased from around 5% at baseline to over 20% at 24 months, with no change in PLHIV receiving EFV- or ATV/r-based ART. High blood pressure in PLHIV switching to DTG was associated with weight gain, with stronger increases in the proportion with high blood pressure for larger weight gains. CONCLUSIONS: Among PLHIV starting ART or switching to a new regimen, DTG-based ART was associated with larger weight gains and a substantial increase in the prevalence of high blood pressure. Routine weight and blood pressure measurement and interventions to lower blood pressure could benefit PLHIV on DTG-based ART. Further studies are needed to elucidate the mechanisms and reversibility of these changes after discontinuation of DTG.

Switching to dolutegravir plus rilpivirine versus maintaining current antiretroviral therapy regimen in virologically suppressed people with HIV-1 and the Lys103Asn (K103N) mutation: 48-week results from a randomised, open-label pilot clinical trial.

BACKGROUND: The combination of dolutegravir plus rilpivirine has been studied in people with virologically suppressed HIV with no previous history of treatment failure or resistance. We investigated the potential to maintain viral suppression with dolutegravir plus rilpivirine in people with Lys103Asn mutations whose HIV was previously managed with other treatment regimens. METHODS: In this open-label pilot trial at 32 clinical sites in seven European countries, virologically suppressed, HBsAg-negative adults aged 18 years or older with HIV-1 and Lys103Asn mutations were randomly assigned (2:1) to switch to 50 mg dolutegravir plus 25 mg rilpivirine (given as a single tablet) once daily or to continue their current antiretroviral therapy regimen (control group). After 48 weeks, participants in the control group also switched to dolutegravir plus rilpivirine. Randomisation was stratified by country, and a computer-generated randomisation list with permuted blocks within strata was used to assign participants to treatment groups. The primary endpoints were virological failure (ie, two consecutive measurements of 50 copies or more of HIV RNA per mL at least 2 weeks apart) and virological suppression (the proportion of participants with fewer than 50 copies of HIV RNA per mL) at week 48 (week 96 data will be reported separately). Analyses were done in the modified intention-to-treat population, which included all participants who received at least one dose of the study medication. This trial is registered with ClinicalTrials.gov, NCT05349838, and EudraCT, 2017-004040-38. FINDINGS: Between Nov 5, 2018, and Dec 9, 2020, 140 participants were enrolled and randomly assigned, 95 to the dolutegravir plus rilpivirine group and 45 to the control group. Virological failure was recorded in three participants (3·2%, 95% CI 0·7 to 9·0) in the the dolutegravir plus rilpivirine group and one (2·2%, 0·1 to 11·8) in the control group. The proportion of participants in whom virological suppression was maintained at week 48 was 88·4% (80·2 to 94·1) in the dolutegravir plus rilpivirine group versus 88·9% (75·9 to 96·3) in the control group (difference -0·5, -11·7 to 10·7). Significantly more adverse events were recorded in the dolutegravir plus rilpivirine group than in the control group (234 vs 72; p=0·0034), but the proportion of participants who reported at least one adverse event was similar between groups (76 [80%] of 95 vs 33 [73%] of 45; p=0·39). The frequency of serious adverse events was low and similar between groups. INTERPRETATION: Virological suppression was maintained at week 48 in most participants with Lys103Asn mutations when they switched from standard regimens to dolutegravir plus rilpivirine. The results of this pilot study, if maintained when the week 96 data are reported, support conduct of a large, well-powered trial of dolutegravir plus rilpivirine. FUNDING: ViiV Healthcare.

DOLAMA 200: Effectiveness and Safety of a Dual Therapy with Dolutegravir Plus Lamivudine in Treatment-Experienced HIV-1 Infected Real World Participants in Spain.

The continuous pharmacological advances in antiretroviral treatment (ART) and the increasing understanding of HIV drug resistance has led to a change in the paradigm of ART optimization in the setting of the viral suppression of treatment-experienced patients with the emerging evidence of the effectiveness and safety of dual therapies. The aim of this study is to determine the antiviral efficacy and safety of switching to Dolutegravir + Lamivudine in people living with HIV, and to analyze the rate of patients with virologic failure (VF). A total of 200 patients were included with a median age of 51 years, 189 cells/µL of nadir CD4+, 13 years on ART and four previous ART regimens. Among the 168 patients who completed a follow-up at 48 weeks, a total of five VFs occurred, resulting in a 2.98% (5/168) VF rate. The results of the intention-to-treat analysis were a VF rate of 2.54% (5/197), and the rate of patients/year with viral suppression was 98.3% (298/303) in the observed data analysis. We observed a significant improvement in mean CD4 lymphocytes, the CD4/CD8 ratio and lipid profiles. The optimization of ART to DTG plus 3TC is a cost-effective switch option for treatment-experienced HIV patients, and also improves their lipid profiles.

Switch to bictegravir/emtricitabine/tenofovir alafenamide from dolutegravir-based therapy.

OBJECTIVE: To evaluate the efficacy and safety of 96 weeks of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) treatment in participants switching from dolutegravir (DTG)-based therapy. DESIGN: Studies 1489 (NCT02607930) and 1490 (NCT02607956) were phase 3 randomized, double-blind, active-controlled, first-line therapy trials in people with HIV-1. After 144 weeks of DTG-based or B/F/TAF treatment, participants could enter a 96-week open-label extension (OLE) of B/F/TAF. METHODS: A pooled analysis evaluated viral suppression (HIV-1 RNA <50 copies/ml) and changes in CD4 + cell count at OLE Weeks 48 and 96, treatment-emergent resistance, safety, and tolerability after switch from a DTG-based regimen to B/F/TAF. Outcomes by prior treatment were summarized using descriptive statistics and compared by two-sided Wilcoxon rank sum test. RESULTS: At OLE Week 96, participants who switched to B/F/TAF ( N  = 519) maintained high levels of virologic suppression (99.5 and 99.1% in those switching from DTG/abacavir/lamivudine and DTG+F/TAF, respectively) and CD4 + cell count, with no treatment-emergent resistance to B/F/TAF. Twenty-one participants experienced drug-related adverse events after switching, with diarrhea, weight gain, and headache occurring most commonly. There were no cases of proximal renal tubulopathy, drug-related Grade 4 adverse events, or serious adverse events. Two participants discontinued B/F/TAF due to treatment-related adverse events. Participants who switched from DTG/abacavir/lamivudine experienced statistically significant greater weight gain than those who switched from DTG+F/TAF; however, median weight change from the blinded phase baseline to OLE Week 96 was numerically similar across treatment groups. CONCLUSION: This medium-term analysis demonstrates the safety and efficacy of switching to B/F/TAF from a DTG-containing regimen in people with HIV-1.

Safety of Upadacitinib in Immune-Mediated Inflammatory Diseases: Systematic Literature Review of Indirect and Direct Treatment Comparisons of Randomized Controlled Trials.

INTRODUCTION: Immune-mediated inflammatory diseases including rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), non-radiographic axial spondylarthritis (nr-axSpA), atopic dermatitis (AD), ulcerative colitis (UC), and Crohn's disease (CD) pose a substantial burden on patients and their quality of life. Upadacitinib is an orally administered, selective, and reversible Janus kinase inhibitor indicated for seven conditions, but data on its safety versus other active treatments are limited. A systematic literature review of indirect and direct treatment comparisons of randomized controlled trials (RCTs) was conducted to assess the safety profile of upadacitinib. METHODS: MEDLINE, Embase, and Cochrane Library databases were searched for indirect and direct treatment comparisons of RCTs that (1) included licensed upadacitinib dosages; (2) studied any of the seven conditions; (3) reported any adverse events (AEs), serious AEs (SAEs), AEs leading to discontinuation, major adverse cardiovascular event, venous thromboembolism, malignancies, infections or serious infections, and death; and (4) were published between January 2018 and August 2022. RESULTS: A total of 25 studies were eligible for inclusion. SAEs, AEs leading to discontinuation, and any AEs were commonly studied. RA was the most studied condition, followed by AD and UC. Most studies (16/25, 64%) reported no statistically significant difference in the studied safety outcomes between upadacitinib and other active treatments (e.g., tumor necrosis factor blockers, interleukin receptor antagonists, integrin receptor antagonists, T cell co-stimulation modulator), or placebo (placebo ± methotrexate or topical corticosteroids). Other studies (9/25, 36%) reported mixed results of no statistically significant difference and either statistically higher (8/25, 32%) or lower rates (1/25, 4%) on upadacitinib. CONCLUSION: Most studies suggested that upadacitinib has no statistically significant difference in the studied safety outcomes compared to active treatments or placebo in patients with RA, PsA, AS, AD, UC, and CD. A few studies reported higher rates, but findings were inconsistent with limited interpretation.

Comparison of dolutegravir and efavirenz on depression, anxiety and sleep disorders in pregnant and postpartum women living with HIV.

BACKGROUND: Both dolutegravir and efavirenz are known to be effective in pregnancy and postpartum to prevent vertical transmission of HIV and to maintain maternal health. Both drugs have also been associated with neuropsychiatric symptoms. To what extent, these symptoms occur in pregnant and postpartum women, however, is not yet known. METHODS: This was a secondary analysis of the DolPHIN2 study, a multicentre randomized trial among women presenting late in pregnancy with untreated HIV - who received either a dolutegravir-containing or efavirenz-containing regimen. Longitudinal measures of depression, anxiety and sleep quality were analysed during pregnancy and up to 48 weeks postpartum. RESULTS: Among 268 women, median (IQR) Edinburgh Post Natal Depression Score (EPDS) scores were 8 (3-11) and highest at enrolment. In the dolutegravir and efavirenz arm, respectively, 23.7 and 25.6% had an EPDS score above 9, indicating possible or probable depression. Abnormal Hospital Anxiety Depression scores (HADS) (above 11) were seen at least once during follow-up in 42 of patients (15.7%), although no differences were seen between treatment arms. No association was found between EPDS, suicidality and HADS scores and the assigned regimen ( P  = 0.93, 0.97 and 0.18 respectively). Median (IQR) Pittsburgh Sleep Quality index (PSQI) scores for dolutegravir and efavirenz were 6 (5-7) and 5 (5-6.5), respectively, P  = 0.70. CONCLUSION: No statistically significant differences were observed between efavirenz-containing or dolutegravir-containing regimens. Rates of depression were high, but decreased over the course of time and confirm the need for psychological support after initial HIV diagnosis in pregnancy.

Effectiveness, Weight Changes, and Metabolic Outcomes on Switch to Generic Dolutegravir/Lamivudine Among People with HIV in Western India: An Observational Study.

We assessed the effectiveness and safety of switching to generic dolutegravir/lamivudine (DTG/3TC) among People living with Human Immunodeficiency Virus (PWH) in Western India. In this single-center, retrospective observational study, PWH, who switched to DTG/3TC, were followed for virologic, immunologic, and clinical effectiveness, and safety, including weight changes, hyperglycemia, and dyslipidemia. Multivariate linear mixed-effects models were used to predict average change in weight adjusted for age, sex, duration of previous antiretroviral (ARV) regimens, and baseline weight. From May 2017 to July 2022, out of 434 PWH switched to DTG/3TC, 304 with at least 1 follow-up visit were included. Median [interquartile range (IQR)] age was 54 (IQR 49-61) years and 70.1% were male. Prevalence of baseline comorbidities was 57.9% (hypertension-41.5%, chronic kidney disease-40.9%, and diabetes mellitus-18.8%). Reasons for switch were affordability (47.4%), desire for simplification (41.8%), ARV toxicities (19.1%), and concern about potential toxicities (10.2%). Median (IQR) duration of follow-up on DTG/3TC was 40 (IQR 31-49) weeks. No virologic failure was observed. Rates of virologic suppression [viral load (VL) ≤20 copies/mL or target not detected (TND)] at 12, 24, 48, 72, 96 and 120 weeks were 95.2%, 95.9%, 90%, 100%, 81.3%, and 88.4%, respectively. Only 9 (3%) PWH permanently discontinued DTG/3TC. Predicted adjusted mean weight gain of +3.3 kg was observed at 96 weeks. Switching from tenofovir disoproxil fumarate (TDF)/emtricitabine or lamivudine (XTC)/non-nucleoside reverse transcriptase inhibitor (NNRTI) and duration on DTG/3TC were significantly associated with weight gain. Apart from trend in worsening hyperglycemia (nine PWH with new onset diabetes), no clinically significant change in lipids and estimated glomerular filtration rate (eGFR) was documented. Switching to DTG/3TC is an effective and safe option among virologically suppressed PWH with high comorbidity burden in India. In view of the several advantages of DTG/3TC, it may be considered for potential scale-up in the right population, both in private and public health care settings in India.

Efficacy and safety of bictegravir/emtricitabine/tenofovir alafenamide fumarate for adult patients with human immunodeficiency virus-1 in China: a retrospective real-world cohort study.

BACKGROUND: This study aimed to evaluate the therapeutic effect and tolerance of bictegravir/emtricitabine/tenofovir alafenamide fumarate (BIC/FTC/TAF) use for 24 weeks in anti-retroviral therapy (ART)-naïve patients in China. METHODS: This single-center retrospective cohort study included ART-naïve patients who received BIC/FTC/TAF from July 2021 to April 2022. The proportion of patients with HIV RNA < 50 copies/mL at the end point of 24 weeks (virological suppression rate) was the primary outcome, and the changes in CD4 cell count, CD4/CD8 ratio, weight, blood lipid, and safety were secondary outcomes. RESULTS: A total of 80 ART-naïve patients were enrolled. The virological suppression rate was 86.3% at 24 weeks. The median CD4 cell count increased from 212 cells/µL (interquartile range [IQR]: 90.3-398.3) at baseline to 348 cells/µL (IQR: 219.8-541.0) at 24 weeks. The median CD4/CD8 ratio increased from 0.25 (IQR: 0.13-0.37) at baseline to 0.40 (IQR: 0.26-0.66) at 24 weeks. During the follow-up of 80 ART-naïve patients using BIC/FTC/TAF, 16 participants had adverse events; however, these events did not lead to drug withdrawal. CONCLUSION: This real-world cohort study showed that BIC/FTC/TAF could achieve good immunological and virological responses in ART-naïve patients. In addition, this study also shows good safety.

Efficacy and Safety of Switching to Dolutegravir/Lamivudine in Virologically Suppressed People Living with HIV-1 Aged Over 65 Years.

Clinical trials of dual regimen dolutegravir/lamivudine (DOL/3TC) demonstrated potent efficacy and favorable safety in both antiretroviral therapy-naïve and -experienced patients, but data on older people are lacking. We aimed to evaluate virological efficacy and safety of DOL/3TC in suppressed older patients over a 12-month period. We performed a retrospective cohort study evaluating people living with HIV (PLWHIV) aged ≥65 years at our HIV Clinic who were switched to DOL/3TC. Eligible patients had baseline HIV-1 RNA <20 copies/mL, and no previous virological failures or known resistance mutations for lamivudine or dolutegravir. Inclusion criteria were met by 72 patients: 59 were men, median age was 69.2 years, and one or more comorbidities were present in 89% of patients. The most common reason for switch was simplification, followed by drug-drug interactions (DDIs) and toxicities. After 12 months, 64 (88.9%, by the intention-to-treat analysis) patients maintained HIV-1 RNA <20 copies/mL, and reasons for treatment failure were virological failure in three cases, adverse events in three, and missing data in two. Genotype resistance testing showed no resistance mutations for lamivudine or dolutegravir in subjects with virological failure. The number of potential DDIs decreased from 92 to 12 after switching to DOL/3TC, and a significant reduction in median total and low-density lipoprotein cholesterol was reported, while median change in body weight was not significant. In this real-life cohort, switching to DOL/3TC was associated with maintenance of virological control and good tolerability among persons aged >65 years, supporting use of this dual regimen in older PLWHIV.
