Adverse Event Assessment of Upadacitinib: A Pharmacovigilance Study Based on the FAERS Database.

PURPOSE: Upadacitinib, a Janus kinase (JAK) inhibitor, has been approved by the FDA to treat various autoimmune conditions. This study assessed its adverse events by analyzing reports from the FDA Adverse Event Reporting System (FAERS). METHODS: FAERS data from Q3 2019 to Q4 2023 were extracted, and disproportionality analyses were conducted using four statistical measures, reporting odds ratio, proportionate reporting ratio, Bayesian confidence propagation neural network, and empirical Bayesian geometric mean. RESULTS: A total of 6 879 398 adverse event reports were collected, with 37 700 reports identifying upadacitinib as the "primary suspected." These reports involved 24 system organ classes and 246 preferred terms that met the criteria across all four algorithms. The distribution of adverse events was assessed separately for female and male patients. Further analysis of the top 25 preferred terms revealed that, although the system organ classes were similar between sexes, the specific adverse events differed. The adverse events were analyzed by gender, showing musculoskeletal and skin disorders were prevalent and severe in male patients, while musculoskeletal issues, infections, and abnormal laboratory tests were common in female patients. Unexpected events like trigger finger, biliary sepsis, and serious events such as oral neoplasm were also identified. CONCLUSION: This study provides real-world evidence for the safety evaluation of upadacitinib and underscores the need to monitor sex-specific adverse events. Future prospective studies are necessary to confirm these pharmacovigilance findings.

The safety of a dolutegravir (DTG)-based antiretroviral treatment (ART) regimen for pregnancy and birth outcomes in Ethiopia: evidence from multicenter cohort study.

BACKGROUND: A dolutegravir (DTG)-based antiretroviral regimen has been rolled out for pregnant women in low- and middle-income countries since 2020. However, available safety data are limited to a few clinical trials and observational studies. Hence, we present real-world pregnancy and birth outcome safety data from a large sample multicenter cohort study in Ethiopia. METHODS: A retrospective cohort study was conducted in fourteen hospitals across Ethiopia from 2017 to 2022. HIV-infected pregnant women were followed from the date of prevention of mother-to-child transmission (PMTCT) care enrolment until the infant was 6-8 weeks old. The primary safety outcome was a composite of adverse pregnancy events comprising spontaneous abortion, intrauterine fetal death (IUFD) before onset of labor, preterm birth, and maternal death. Additionally, a composite adverse birth outcome was assessed, comprising intrapartum fetal demise, low birth weight, and neonatal death. Finally, a composite of adverse pregnancy or birth outcome was also investigated. The exposure of interest was the antiretroviral treatment (ART) regimen used during pregnancy for PMTCT of HIV. RESULTS: During the study period, 2643 women were enrolled in routine PMTCT care. However, 2490 (92.2%) participants were eligible for the study. A total of 136/1724 (7.9%, 95% CI: 6.7-9.3%) women experienced adverse pregnancy outcomes. Fewer women in the DTG-based group (5.4%, 95% CI: 3.7-7.5%) had adverse pregnancy outcomes than in the Efavirenz (EFV)-based group (8.3%, 95% CI: 6.6-10.3%), P = 0.004. After controlling for baseline differences, the DTG group had a 43% lower risk of adverse pregnancy outcomes (adjusted odd ratio (AOR), 0.57; 95% CI, 0.32-0.96%) and a 53% lower risk of preterm birth (AOR, 0.47; 95% CI, 0.22-0.98%) compared to the EFV group. A total of 103/1616 (6.4%, 95% CI: 5.2-7.7%) women had adverse birth outcomes. Although the difference was not statistically significant, fewer women in the DTG group (30/548; 5.5%, 95% CI: 3.7-7.7%) than in the EFV group (57/830; 6.9%, 95% CI: 5.2-8.8%) had adverse birth outcomes. CONCLUSIONS: In this study, we observed that DTG-based regimens were associated with better pregnancy and birth outcome safety profiles, reaffirming the WHO recommendation. However, a prospective study is recommended to assess uncaptured maternal and perinatal adverse outcomes, such as congenital abnormalities, and infant growth and neurocognitive development.

Effectiveness and safety of upadacitinib in acute severe ulcerative colitis patients from single Chinese IBD Center: a monocentric study.

Upadacitinib is an oral new selective JAK1 inhibitor that has been approved for treating adult patients with moderately to severely active ulcerative colitis. However, a growing number of studies are needed on the effectiveness of upadacitinib in the treatment of acute severe ulcerative colitis. This study was mainly aimed to describe the clinical and endoscopic effectiveness of upadacitinib 45 mg in Chinese acute severe ulcerative colitis patients following eight weeks of treatment. In this study, we examined all patients with acute severe ulcerative colitis from Xijing IBD Center, Xi'an, China, with acute severe ulcerative colitis. All patients were initially given oral upadacitinib 45 mg. Clinical indicators, C-reactive protein, and erythrocyte sedimentation rates were collected. Clinical response and clinical remission were assessed using modified Mayo. Endoscopic evaluation was performed carried out using the Mayo Endoscopic Score and Ulcerative colitis endoscopic index of severity score. A total of 14 patients who received upadacitinib were included in the study period. All patients exhibited a clinical response to 45 mg upadacitinib initially. All patients completed the 8-week induction. The clinical remission rate was 28.6% after eight weeks. Two patients revealed endoscopic remission at 14.3%. The pathology improved in 50.0% of patients. The 8-week surgical resection rate was 7.1%, with the 16-week surgical resection rate being 14.3%. Adverse events included herpes simplex virus infection and increased thrombin time. The results of our study support the short-term effectiveness and safety of upadacitinib in acute severe ulcerative colitis, providing new choices for patients' treatment. However, more extended investigation needs to be performed on the long-term effectiveness and safety.

Efficacy and safety of upadacitinib in the treatment of moderate-to-severe atopic dermatitis in adolescents: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: To assess the efficacy and safety of upadacitinib in adolescents with moderate-to-severe atopic dermatitis (AD). METHODS: A comprehensive search was conducted using PubMed, Medline, Embase, Web of Science, Clinical Trials Website, and Cochrane Library databases, spanning from their inception until February 18, 2024. The review incorporated all randomized controlled trials examining upadacitinib's efficacy in managing moderate to severe AD among adolescent patients. The methodological quality of the selected studies underwent thorough assessment utilizing the Cochrane systematic review methodology. Statistical analyses of the outcome measures were executed employing the Review Manager 5.3 software. RESULTS: The meta-analysis encompassed 4 studies in total. Compared to placebo, upadacitinib at doses of both 15 and 30 mg was associated with a significant enhancement in the eczema area and severity index-75% ([odds ratio, OR = 11.06, 95% confidence interval, CI (6.78-18.04), P < .00001]; [OR = 21.73, 95% CI (12.73-37.11), P < .00001]), a reduction in the numerical rating scale of ≥4 ([OR = 6.16, 95% CI (3.56-10.64), P < .00001]; [OR = 10.58, 95% CI (6.12-18.29), P < .00001]), and improvement in the investigator's global assessment to 0/1 ([OR = 8.85, 95% CI (4.86-16.10), P < .00001]; [OR = 21.43, 95% CI (11.64-39.46), P < .00001]). Regarding safety, upadacitinib at both 15 and 30 mg doses was linked to a statistically significant rise in the overall incidence of adverse events when juxtaposed with placebo ([OR = 1.57, 95% CI (1.01-2.44), P = .04]; [OR = 2.21, 95% CI (1.44-3.41), P = .0003]). Nevertheless, no statistically significant disparity was discovered in the occurrence of serious adverse events between upadacitinib and placebo ([OR = 1.02, 95% CI (0.27-3.84), P = .98]; [OR = 0.42, 95% CI (0.09-1.93), P = .26]). CONCLUSION: The findings from this meta-analysis indicate that upadacitinib demonstrates substantial effectiveness and tolerability in treating moderate to severe AD in adolescents. Moreover, upadacitinib provides a rapid reduction in pruritus and markedly ameliorates symptoms and signs, with the 30 mg dosage showing a more pronounced therapeutic effect relative to the 15 mg dosage.

Risk of Congenital Anomalies with Dolutegravir-Based Anti-retroviral Regimens: A Systematic Review and Meta-analysis.

BACKGROUND AND OBJECTIVES: Dolutegravir has been used as a first-line anti-human immunodeficiency virus drug because of its better efficacy compared with other counterpart medicines. However, making a unanimous decision on its use during pregnancy has become difficult for stakeholders following congenital anomalies reported with its use. The objective of this systematic review and meta-analysis was to study the risk of congenital anomalies in newborns exposed to dolutegravir-based-regimens compared with those exposed to non-dolutegravir-based regimens during the antenatal period. METHODS: An extensive literature search was performed in MEDLINE (through PubMed), EMBASE, Cochrane Database of Systematic Reviews, Google Scholar, and ClinicalTrials.gov until 30 November, 2023. Studies reporting data on congenital anomalies following antenatal use of dolutegravir were included. Risk of bias for randomized controlled trials, non-randomized controlled trials, and observational studies was assessed using RoB2, ROBINS-I, and ROBINS-E tools, respectively. A meta-analysis was performed in 'RevMan 5.4.1' using a random-effects model. Heterogeneity was assessed by the 'Q' statistic and I2 value. A sensitivity analysis was performed for higher heterogeneity/high-risk studies. The study protocol was registered in PROSPERO [CRD42023446374] a priori. RESULTS: Of 26 eligible studies, 12 (six randomized controlled trials and six observational studies with a pooled sample of 32,617) were included in a meta-analysis and 14 in a qualitative synthesis only. The meta-analysis does not show a statistically significant difference in the risk of congenital anomalies between newborns exposed antenatally to dolutegravir-based regimen(s) and those exposed to non-dolutegravir-based regimens [risk ratio 1.10; 95% confidence interval 0.79-1.53; p = 0.59]. Heterogeneity was moderate (I2 = 47%). Pooled results for randomized controlled trials and observational studies separately and the sensitivity analysis for heterogeneity provided similar results. CONCLUSIONS: The risk of congenital anomalies was not significantly different between dolutegravir-based regimens and non-dolutegravir-based-regimens in newborns exposed during their antenatal period.

An observational cohort study to investigate the impact of dolutegravir in pregnancy and its obesogenic effects on the metabolic health of women living with HIV and their children: Study protocol.

INTRODUCTION: Dolutegravir (DTG)-based antiretroviral therapy is the World Health Organization's preferred first-line regimen for all persons with HIV, including pregnant women. While DTG has been implicated as an obesogen associated with greater weight gain compared to other antiretrovirals, there is a paucity of data in pregnant women and their children. The Obesogenic oRigins of maternal and Child metabolic health Involving Dolutegravir (ORCHID) study is investigating associations between DTG, weight gain, and metabolic outcomes in the context of HIV. MATERIALS & METHODS: ORCHID is a prospective observational study taking place in Cape Town, South Africa (NCT04991402). A total of 1920 pregnant women with and without HIV infection are being followed from ≤18 weeks gestational age to 24 months postpartum with their children. Participants attend eleven study visits: 3 antenatal, delivery, and 7 postnatal visits. Several embedded sub-studies address specific scientific aims. Primary outcome measurements in mothers include anthropometry, blood pressure, body composition, dysglycemia, insulin resistance (IR), and dyslipidemia. Other maternal measures include demographics, resting energy expenditure, viral load, physical activity, dietary intake, hepatic steatosis, and repository specimens. Sub-study measurements include markers of adipose inflammation, gut integrity, and satiety/hunger, subcutaneous adipose tissue morphology and mitochondrial function, and metabolomics. Primary outcome measurements in children include anthropometry, adipose tissue mass, dysglycemia, IR, and dyslipidemia. Other variables include fetal growth, birth outcomes, medical/breastfeeding history, caloric intake, neurodevelopment, and repository specimens. Sub-study measurements include metabolites/lipid subspecies in umbilical cord blood, as well as breast milk composition and DTG exposure. DISCUSSION: ORCHID will play a pivotal role in defining obesogenic mechanisms and clinical consequences of DTG use in pregnancy in women with HIV and their children. It will provide insights into metabolic disease risk reduction in the context of HIV/DTG, identify intervention targets, and inform public health approaches to diminish chronic metabolic co-morbidities for women and children.

Comparative Efficacy and Safety of Upadacitinib vs. Vedolizumab, Ustekinumab, and Tofacitinib After Induction and Maintenance for Ulcerative Colitis: Three Matching-Adjusted Indirect Comparisons.

INTRODUCTION: Evidence on the comparative efficacy and safety of approved therapies for ulcerative colitis (UC) during induction and maintenance, including upadacitinib (UPA), vedolizumab (VEDO), ustekinumab (UST), and tofacitinib (TOFA), is limited. METHODS: Using data from phase 3 trials, three placebo (PBO)-anchored matching-adjusted indirect comparisons of the efficacy and safety of UPA versus VEDO, UST, and TOFA (U-ACHIEVE and U-ACCOMPLISH, GEMINI-1, UNIFI, and OCTAVE induction and maintenance trials) have been conducted. Baseline characteristics from UPA trials were weighted separately to match each comparator trial. Induction responders were re-randomized to oral UPA 15 or 30 mg, VEDO 300 mg intravenously every 8 weeks (Q8W), UST 90 mg SC Q8W, or oral TOFA 5 mg, or PBO in maintenance. Treat-through efficacy outcomes at weeks 44(UST)/46(VEDO)/52(UPA/TOFA) were adjusted by the likelihood of induction response and included clinical response, clinical remission, and endoscopic improvement. Safety outcomes included adverse events (AEs), serious AEs (SAEs), and AEs leading to discontinuation (except UPA vs. VEDO). Benefit-risk was assessed by numbers needed to treat (NNT)/harm, calculated as the inverse of the difference in proportions of patients achieving each efficacy/safety outcome for UPA versus comparator. RESULTS: The proportions of patients who demonstrated clinical response or endoscopic improvement was greater with UPA 15 mg versus VEDO and TOFA (p < 0.05). The proportions of patients demonstrating all treat-through efficacy outcomes were significantly greater with UPA 30 mg versus VEDO, UST, or TOFA with NNTs 3.2-8.7. No significant differences in proportions of AEs, SAEs, and AEs leading to discontinuation were observed between the two doses of UPA and comparators. CONCLUSION: In patients with active UC, greater clinical efficacy, and similar safety after 1 year of maintenance were observed with UPA versus VEDO, UST, and TOFA, suggesting a favorable benefit-risk profile for UPA. Despite matched baseline characteristics, differences in trial design and endpoints may persist.

Case report: Psoriasiform eczema with immune-mediated comorbidities treated with upadacitinib.

Immune-mediated comorbidities in patients with psoriasiform eczema are common. It can be challenging to manage multiple immune-mediated diseases, especially considering that biologic treatments are prone to causing paradoxical effects. The aim of this retrospective observational case series was to describe the course of both psoriasiform eczema and immune-mediated comorbidities in five patients treated with upadacitinib for psoriasiform dermatitis. Five patients, all male, were included. All the patients suffered from psoriasiform eczema. Moreover, two of the patients suffered from alopecia areata, two from vitiligo, one from ulcerative colitis and one from hidradenitis suppurativa. In all cases, the treatment with upadacitinib was rapidly effective on the eczema. The effectiveness on alopecia areata was good in both cases, while the results on vitiligo were only partial. The only case of ulcerative colitis achieved complete remission, while the case of hidradenitis suppurativa experience partial improvement. In conclusion, upadacitinib was effective in treating not only psoriasiform eczema, but also several immune mediated comorbidities. Additional studies are necessary to determine the efficacy of upadacitinib in alopecia areata, vitiligo and hidradenitis suppurativa.

Oral Janus Kinase Inhibitors in Pediatric Atopic Dermatitis.

PURPOSE OF REVIEW: To analyze the efficacy and safety of Janus kinase inhibitors (JAKi) in the treatment of pediatric AD. RECENT FINDINGS: Adolescents with moderate and severe atopic dermatitis (AD) need systemic therapies, as stated several recent practice guidelines. (JAKi) have shown their efficacy in the treatment of adult AD, however, there is a lack of information concerning efficacy and safety of their use in pediatric AD. We found that the JAKi's abrocitinib (ABRO), baricitinib (BARI), and upadacitinib (UPA), are all an effective treatment option with a very fast onset of action for adolescents with moderate-to-severe AD. BARI was not effective in children between 2 and 10 years with moderate-to-severe AD. Fortunately, major safety issues with JAKi in adolescents with AD have not been documented in the trials, so far, contrasting with the reports in adults with AD, where these events have very rarely occurred. There are some reports of herpes zoster (HZ) infection in adolescents on JAKi, but it is not a major safety concern. Acne is a relatively common AE with UPA in adolescents; however, it is responsive to standard treatment. This review will help the clinician to choose among the JAKi according to the needs and clinical features of patients with moderate and severe AD. In the following years, with the advent of new biologicals and JAKi, these therapies will fall into place in each phase of the evolution of patients with AD.

Integrase inhibitor drugs during pregnancy and congenital anomalies: A case/non-case study from the global pharmacovigilance database VigiBase®.

In 2018, a significant neural tube defects (NTD) signal was reported after pre-conceptional exposure to dolutegravir, but was not confirmed in further analysis. Since 2019, dolutegravir-based regimen, an integrase inhibitor (INI), is recommended by WHO as the most-effective first-line therapy in all patients living with HIV. To explore the potential INI-related teratogenic effect, we searched disproportionate signals between exposure to INI-class drugs and congenital anomalies, compared to non-INI drugs, using the international pharmacovigilance database, VigiBase®. We selected all the reports registered in VigiBase® between 01/01/2007 and 30/03/2021 on any antiretroviral drug-related fetal or neonatal adverse drug reactions, declared either in children (<2 years) exposed in utero or in pregnant women (12-50 years). A case/non-case study was conducted to detected signals between congenital anomalies and prenatal exposure to any INI-class drug, compared to non-INI drugs, by estimating adjusted reporting odds ratios (aROR) with 95% confidence intervals (95%CI). We identified 2521 unique reports, among which 664 (26.3%) were related to INI-class use. Overall, 520 congenital anomalies were cited from 327 unique reports, of whom 31.0% were INI-related. Compared to non-INI drugs, no significant disproportionate reporting signal between prenatal exposure to INI-class drugs and congenital anomalies was found (aROR 1.13; 95% CI:0.85-1.51). However, specific significant signals were reported for raltegravir/elvitegravir/dolutegravir drug exposure and urinary malformations (aROR 2.43; 95%CI:1.08-5.43), digestive malformations (aROR 3.09; 95%CI:1.22-7.84), and NTDs (aROR 3.02; 95%CI:1.09-8.37). Although specific congenital anomalies signals associated with raltegravir/elvitegravir/dolutegravir exposure were notified, causal relationship needs to be further investigated in prospective studies.

Twelve-month effectiveness and safety of bictegravir/emtricitabine/tenofovir alafenamide in treatment-naïve and treatment-experienced people with HIV: Findings from the Asia cohort of the BICSTaR study.

BACKGROUND: The ongoing, observational BICSTaR (BICtegravir Single Tablet Regimen) cohort study is evaluating real-world effectiveness and safety of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in people with HIV across 14 countries over 24 months. We present 12-month data from the BICSTaR Asia cohort. METHODS: Data were pooled from retrospective and prospective cohorts of antiretroviral therapy (ART)-naïve (hereafter, TN) and ART-experienced (hereafter, TE) people with HIV (aged ≥21 years) receiving B/F/TAF in routine clinical care in the Republic of Korea, Singapore, and Taiwan. Analyses included effectiveness (primary endpoint: HIV-1 RNA <50 copies/ml, missing = excluded analysis), CD4 count, CD4/CD8 ratio, safety, treatment persistence, and patient-reported outcomes (prospective group). RESULTS: The analysis population included 328 participants (80 retrospective, 248 prospective; 65 TN, 263 TE). Participants were predominantly male (96.9% TN, 93.2% TE) with ≥1 comorbidity (52.3% TN, 57.8% TE); median age (years) was 31 (TN) and 42 (TE). Following 12 months of B/F/TAF, HIV-1 RNA was <50 copies/ml in 98.2% (54/55) of TN and 97.0% (227/234) of TE participants. Median (Q1, Q3) CD4 cell count increased by +187 (119, 291) cells/µl in the TN group (p < 0.001) and remained stable (+8 [-91, 110] cells/µl) in the TE group. B/F/TAF persistence was high in the prospective group, with 1/34 (2.9%) TN and 5/214 (2.3%) TE participants discontinuing treatment within 12 months. Drug-related adverse events occurred in 5.8% (19/328) of participants, leading to treatment discontinuation in 0.6% (2/328). CONCLUSIONS: Real-world evidence from BICSTaR supports the effectiveness, safety and tolerability of B/F/TAF in people with HIV in Asia.

Pregnancy Outcomes in Patients Treated with Upadacitinib: Analysis of Data from Clinical Trials and Postmarketing Reports.

BACKGROUND AND OBJECTIVE: Upadacitinib is indicated for diseases affecting persons of childbearing potential including rheumatoid arthritis, psoriatic arthritis, axial spondyloarthritis, atopic dermatitis, Crohn's disease, and ulcerative colitis; however, teratogenicity was observed in animal studies. Given the potential for human fetal risk, pregnancy avoidance measures were required during clinical trials. This analysis describes pregnancy outcomes in patients exposed to upadacitinib during pregnancy. METHODS: Clinical trial and postmarketing cases of in utero exposure to upadacitinib were identified in AbbVie's safety database through 25 April, 2023. Analysis of clinical trial cases and postmarketing reports are presented separately; prospective and retrospectively reported pregnancy outcomes are integrated for each. Descriptive rates are presented to summarize outcomes. RESULTS: There were 128 maternal upadacitinib-exposed pregnancies with known outcomes identified; 80 and 48 pregnancies were reported in clinical trials and the postmarketing setting, respectively. In clinical trials (mean in utero exposure of 5 weeks, 3 days), live births (54%), spontaneous abortions (24%), elective terminations (21%), and ectopic pregnancy (1%) were reported. There was one report of a congenital malformation: a 35-week infant with an atrial septal defect. In postmarketing cases, live births (46%), spontaneous abortions (38%), elective terminations (15%), and ectopic pregnancy (2%) were reported. CONCLUSIONS: As the data are limited for in utero exposure to upadacitinib, definitive conclusions cannot be drawn regarding the effect of upadacitinib on pregnancy outcomes. Rates of adverse pregnancy outcomes with upadacitinib exposure were comparable to rates observed in the general population or patients with autoimmune inflammatory diseases. To date, no apparent evidence of teratogenicity exists in the analyses of human pregnancies exposed to upadacitinib during the first trimester.

Efficacy and safety of upadacitinib in patients with rheumatoid arthritis and inadequate response or intolerance to biological treatments: results through 5 years from the SELECT-BEYOND study.

OBJECTIVE: To evaluate the efficacy and safety of upadacitinib over 5 years among patients with rheumatoid arthritis (RA) in a long-term extension (LTE) of the SELECT-BEYOND phase 3 trial. METHODS: Patients refractory to ≥1 biological disease-modifying antirheumatic drug (DMARD) received upadacitinib 15 mg or 30 mg once daily or placebo, in combination with background conventional synthetic DMARD(s). At week 12, patients randomised to placebo were switched to upadacitinib 15 mg or 30 mg. All patients who completed the week 24 visit could enter the LTE for up to 5 years. Efficacy was analysed as observed and by non-responder imputation through week 260. Treatment-emergent adverse events per 100 patient-years were summarised over 5 years. RESULTS: Of the 498 patients randomised, 418 (84%) completed week 24 and entered the LTE. Of those who remained in the trial (n=80, upadacitinib 15 mg; n=81, upadacitinib 30 mg), 36%/36% and 81%/77% randomised to upadacitinib 15/30 mg were in Clinical Disease Activity Index (CDAI) remission or low disease activity at week 260, respectively (as observed). Approximately 47% of all patients who began in high disease activity demonstrated a CDAI improvement >12 at week 260 with upadacitinib 15/30 mg. Functional and pain-related outcomes also showed comparable improvements with both doses. Numerically higher rates of anaemia, herpes zoster and creatine phosphokinase elevation were observed with upadacitinib 30 mg vs 15 mg. No new safety issues were identified. CONCLUSIONS: Upadacitinib 15/30 mg continued to be effective in treating clinical and functional outcomes in patients with RA. The safety profile observed over 5 years was consistent with earlier study-specific and integrated assessments of upadacitinib treatment.

Rapid initiation of bictegravir/emtricitabine/tenofovir alafenamide as first-line therapy in HIV infection. A prospective study.

INTRODUCTION: Rapid initiation of ART after HIV diagnosis is recommended for individual and public health benefits. However, certain clinical and ART-related considerations hinder immediate initiation of therapy. METHODS: An open-label, single-arm, single-centre 48-week prospective clinical trial involving ART-naïve HIV-diagnosed adults who started bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) within a week from the first hospital visit, before the availability of baseline laboratory and genotype results. The primary aim was to determine the proportion of people with at least one condition that would hinder immediate initiation of any recommended ART regimen other than BIC/FTC/TAF. Clinicaltrials.gov: NCT04416906. RESULTS: We included 100 participants: 79% men, 64% from Latin America, median age 32 years. According to European AIDS Clinical Society (EACS) and US Department of Health and Human Services 2023 guidelines, 11% (95%CI 6; 19) of participants had at least one condition that made any ART different from BIC/FTC/TAF less appropriate for a rapid ART strategy. Seventy-nine percent of the people started BIC/FTC/TAF within the first 48 hours of their first hospital visit. There were 16 early discontinuations (11 lost to follow-up). By week 48, 92% (95%CI 86; 98) of the participants of the ITT population with observed data achieved viral suppression. Eight grade 3-4 adverse events (AEs), five serious AEs and six ART-related AEs were identified. Adherence remained high. CONCLUSIONS: BIC/FTC/TAF is an optimal treatment for rapid initiation of ART. However, additional strategies to improve retention in care must be implemented.

Real-world comparative study of drug retention of Janus kinase inhibitors in patients with rheumatoid arthritis.

BACKGROUND: Janus kinase (JAK) inhibitors (JAKis) are effective therapeutic agents against rheumatoid arthritis (RA). However, patients having RA with particular risk factors may have a higher incidence of adverse effects (AEs), including major cardiovascular events (MACE) and infections. In this multicenter cohort study, we aimed to clarify the risk factors affecting the drug retention of JAKis in patients with RA. METHODS: We retrospectively evaluated patients with RA who received their first JAKi (tofacitinib, baricitinib, upadacitinib, or filgotinib) at our institute. The clinical outcomes, including AEs, were recorded, particularly MACE and serious infections. The drug retention rates were analyzed using the Kaplan-Meier method, and risk factors affecting drug retention rates were determined using a multivariable Cox regression hazards model. RESULTS: Overall 184 patients with RA receiving their first use of baricitinib (57.6%), tofacitinib (23.9%), upadacitinib (12.0%), or filgotinib (6.5%) were included in this study. Fifty-six (30.4%) patients discontinued JAKi treatment owing to ineffectiveness (9.2%) or AEs, including infections (21.2%). The overall drug retention rates were significantly lower in patients treated with pan-JAKi than in those treated with JAK1 inhibitors (p = 0.03). In the Cox regression model, the presence of baseline high RA disease activity, use of glucocorticoid and treatments with pan-JAKis were associated with reduced drug retention rates of JAKis (p < 0.001, p = 0.01 and 0.04, respectively). Pan-JAKi treated patients with high disease activity had significantly lower drug retention rates (p < 0.001). CONCLUSIONS: In a real-world setting, the drug retention rates of JAKis were reduced mainly by treatment discontinuation owing to AEs. Treatment with pan-JAKis and high baseline RA disease activity were identified as predictive factors for the discontinuation of JAKis. Lower drug retention rates were found in patients receiving pan-JAKis with high disease activity than in those without high disease activity.

Cumulative incidence and risk of infection in patients with rheumatoid arthritis treated with janus kinase inhibitors: A systematic review and meta-analysis.

Patients with rheumatoid arthritis (RA) who receive immunosuppressive medications have a heightened risk of infection. The goal of our study was to calculate the pooled cumulative incidence and risk of infection in patients with RA treated with Janus kinase inhibitors (JAKi). The PubMed and EMBASE databases were queried for randomized controlled trials comparing patients with RA treated with JAKi (upadacitinib, baricitinib, tofacitinib, peficitinib, or filgotinib), defined as the treatment group, compared with control subjects, defined as participants receiving placebo or treatment regimen that was similar to that of participants in the treatment group, with the exception of JAKi. The primary study endpoint was the relative risk (RR) of any-grade and severe infection. The secondary endpoints were RR and cumulative incidence of opportunistic infections, herpes zoster, and pneumonia. The Stata v17 software was used for all data analysis. Results showed that treatment with baricitinib was associated with an increased risk of any-grade (RR 1.34; 95% CI: 1.19-1.52) and opportunistic (RR 2.69; 95% CI: 1.22-5.94) infection, whereas treatment with filgotinib (RR 1.21; 95% CI: 1.05-1.39), peficitinib (RR 1.40; 95% CI: 1.05-1.86) and upadacitinib (RR 1.30; 95% CI: 1.09-1.56) was associated with increased risk of any-grade infection only. Analysis based on type of infection showed a pooled cumulative incidence of 32.44% for any-grade infections, 2.02% for severe infections, 1.74% for opportunistic infections, 1.56% for herpes zoster, and 0.49% for pneumonia in patients treated with any JAKi during the follow-up period. Treatment with specific JAKi in patients with RA is associated with an increased risk of any-grade and opportunistic infections but not severe infection. Close clinical monitoring of patients with RA treated with JAKi is required to establish the long-term infection risk profile of these agents.
