Safety and adherence of bictegravir/emtricitabine/tenofovir alafenamide for HIV post-exposure prophylaxis among adults in Guiyang China: a prospective cohort study.

BACKGROUND: The effectiveness of post-exposure prophylaxis (PEP) depends on participants adherence, making it crucial to assess and compare regimen options to enhance human immunodeficiency virus (HIV) prophylaxis strategies. However, no prospective study in China has shown that the completion rate and adherence of single-tablet regimens in HIV PEP are higher than those of multi-tablet preparations. Therefore, this study aimed to assess the completion rate and adherence of two HIV PEP regimens. METHODS: In this single-center, prospective, open-label cohort study, we included 179 participants from May 2022 to March 2023 and analyzed the differences in the 28-day medication completion rate, adherence, safety, tolerance, and effectiveness of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) and tenofovir disoproxil fumarate, emtricitabine, and dolutegravir (TDF/FTC + DTG). RESULTS: The PEP completion rate and adherence were higher in the BIC/FTC/TAF group than in the TDF/FTC + DTG group (completion rate: 97.8% vs. 82.6%, P = 0.009; adherence: 99.6 ± 2.82% vs. 90.2 ± 25.29%, P = 0.003). The incidence of adverse reactions in the BIC/FTC/TAF and TDF/FTC + DTG groups was 15.2% and 10.3% (P = 0.33), respectively. In the TDF/FTC + DTG group, one participant stopped PEP owing to adverse reactions (1.1%). No other participants stopped PEP due to adverse events. CONCLUSIONS: BIC/FTC/TAF and TDF/FTC + DTG have good safety and tolerance as PEP regimens. BIC/FTC/TAF has a higher completion rate and increased adherence, thus, is recommended as a PEP regimen. These findings emphasize the importance of regimen choice in optimizing PEP outcomes. TRIAL REGISTRATION: The study was registered in the Chinese Clinical Trial Registry (registration number: ChiCTR2200059994(2022-05-14), https://www.chictr.org.cn/bin/project/edit?pid=167391 ).

Feasibility, safety, efficacy and potential scaling-up of sofosbuvir-based HCV treatment in Central and West Africa: (TAC ANRS 12311 trial).

Access to Hepatis C treatment in Sub-Saharan Africa is a clinical, public health and ethical concern. The multi-country open-label trial TAC ANRS 12311 allowed assessing the feasibility, safety, efficacy of a specific care model of HCV treatment and retreatment in patients with hepatitis C in Sub Saharan Africa. Between November 2015 and March 2017, with follow-up until mid 2019, treatment-naïve patients with HCV without decompensated cirrhosis or liver cancer were recruited to receive 12 week-treatment with either sofosbuvir + ribavirin (HCV genotype 2) or sofosbuvir + ledipasvir (genotype 1 or 4) and retreatment with sofosbuvir + velpatasvir + voxilaprevir in case of virological failure. The primary outcome was sustained virological response at 12 weeks after end of treatment (SVR12). Secondary outcomes included treatment adherence, safety and SVR12 in patients who were retreated due to non-response to first-line treatment. The model of care relied on both viral load assessment and educational sessions to increase patient awareness, adherence and health literacy. The study recruited 120 participants, 36 HIV-co-infected, and 14 cirrhotic. Only one patient discontinued treatment because of return to home country. Neither death nor severe adverse event occurred. SVR12 was reached in 107 patients (89%): (90%) in genotype 1 or 2, and 88% in GT-4. All retreated patients (n = 13) reached SVR12. HCV treatment is highly acceptable, safe and effective under this model of care. Implementation research is now needed to scale up point-of-care HCV testing and SVR assessment, along with community involvement in patient education, to achieve HCV elimination in Sub-Saharan Africa.

Switch to fixed-dose doravirine (100 mg) with islatravir (0·75 mg) once daily in virologically suppressed adults with HIV-1 on bictegravir, emtricitabine, and tenofovir alafenamide: 48-week results of a phase 3, randomised, controlled, double-blind, non-inferiority trial.

BACKGROUND: Doravirine and islatravir is an investigational, once-daily regimen with high antiviral potency, favourable safety and tolerability, and a low propensity for resistance. We investigated a switch from bictegravir, emtricitabine, and tenofovir alafenamide to doravirine (100 mg) and islatravir (0·75 mg) in virologically suppressed adults with HIV-1. METHODS: We conducted a phase 3, multicentre, randomised, active-controlled, double-blind, double-dummy, non-inferiority trial at 89 research, community, and hospital-based clinics in 11 countries. Adults aged 18 years or older with fewer than 50 HIV-1 RNA copies per mL for at least 3 months on bictegravir (50 mg), emtricitabine (200 mg), and tenofovir alafenamide (25 mg) and no history of previous virological failure on any past or current regimen were randomly assigned (1:1) by a computer-generated randomisation allocation schedule, with block randomisation based on a block size of four, to switch to doravirine (100 mg) and islatravir (0·75 mg) or continue bictegravir, emtricitabine, and tenofovir alafenamide orally once daily, with matching placebos taken by all participants. Participants, investigators, study staff, and sponsor personnel involved in study drug administration or clinical evaluation of participants were masked to treatment assignment until week 48. Participants were instructed at each visit to take one tablet from each of the two bottles received, one of study drug and one of placebo, once daily, and participants were assessed at baseline and weeks 4, 12, 24, 36, and 48. The primary endpoint was the proportion of participants with greater than or equal to 50 HIV-1 RNA copies per mL at week 48 in the full analysis set (ie, all participants who received at least one dose of study drug; US Food and Drug Administration snapshot; prespecified non-inferiority margin 4%). The study is ongoing, with all remaining participants in post-treatment follow-up, and is registered with ClinicalTrials.gov, NCT04223791. FINDINGS: We screened 726 individuals for eligibility between Feb 18 and Sept 3, 2020, of whom 643 (88·6%) participants were randomly assigned to a treatment group (183 [28·5%] women and 460 [71·5%] men). 322 participants were switched to doravirine (100 mg) and islatravir (0·75 mg) and 321 continued bictegravir, emtricitabine, and tenofovir alafenamide (two participants [one with a protocol deviation and one who withdrew] assigned to bictegravir, emtricitabine, and tenofovir alafenamide did not receive treatment). The last follow-up visit for the week 48 analysis occurred on Aug 26, 2021. At week 48, two (0·6%) of 322 participants in the doravirine and islatravir group compared with one (0·3%) of 319 participants in the bictegravir, emtricitabine, and tenofovir alafenamide group had greater than or equal to 50 HIV-1 RNA copies per mL (difference 0·3%, 95% CI -1·2 to 2·0). The per-protocol analysis showed consistent results. 25 (7·8%) participants in the doravirine and islatravir group had headache compared with 23 [7·2%] participants in the bictegravir, emtricitabine, and tenofovir alafenamide group; 101 (31·4%) compared with 98 (30·7%) had infections; and eight (2·5%) participants in each group discontinued therapy due to adverse events. 32 (9·9%) participants had treatment-related adverse events in the islatravir and doravirine group comapred with 38 (11·9%) in the bictegravir, emtricitabine, and tenofovir alafenamide group. In the islatravir and doravirine group, CD4 cell counts (mean change -19·7 cells per µL) and total lymphocyte counts (mean change -0·20 × 109/L) were decreased at 48 weeks. INTERPRETATION: Switching to daily doravirine (100 mg) and islatravir (0·75 mg) was non-inferior to bictegravir, emtricitabine, and tenofovir alafenamide at week 48. However, decreases in CD4 cell and total lymphocyte counts do not support the further development of once-daily doravirine (100 mg) and islatravir (0·75 mg).

(S)-(-)-blebbistatin O-benzoate has the potential to improve atopic dermatitis symptoms in NC/Nga mice by upregulating epidermal barrier function and inhibiting type 2 alarmin cytokine induction.

Atopic dermatitis is a multi-pathogenic disease characterized by chronic skin inflammation and barrier dysfunction. Therefore, improving the skin's ability to form an epidermal barrier and suppressing the production of cytokines that induce type 2 inflammatory responses are important for controlling atopic dermatitis symptoms. (-)-Blebbistatin, a non-muscle myosin II inhibitor, has been suggested to improve pulmonary endothelial barrier function and control inflammation by suppressing immune cell migration; however, its efficacy in atopic dermatitis is unknown. In this study, we investigated whether (S)-(-)-blebbistatin O-benzoate, a derivative of (-)-blebbistatin, improves dermatitis symptoms in a mite antigen-induced atopic dermatitis model using NC/Nga mice. The efficacy of the compound was confirmed using dermatitis scores, ear thickness measurements, serum IgE levels, histological analysis of lesions, and filaggrin expression analysis, which is important for barrier function. (S)-(-)-Blebbistatin O-benzoate treatment significantly reduced the dermatitis score and serum IgE levels compared to those in the vehicle group (p < 0.05). Furthermore, the histological analysis revealed enhanced filaggrin production and a decreased number of mast cells (p < 0.05), indicating that (S)-(-)-blebbistatin O-benzoate improved atopic dermatitis symptoms in a pathological model. In vitro analysis using cultured keratinocytes revealed increased expression of filaggrin, loricrin, involucrin, and ceramide production pathway-related genes, suggesting that (S)-(-)-blebbistatin O-benzoate promotes epidermal barrier formation. Furthermore, the effect of (S)-(-)-blebbistatin O-benzoate on type 2 alarmin cytokines, which are secreted from epidermal cells upon scratching or allergen stimulation and are involved in the pathogenesis of atopic dermatitis, was evaluated using antigens derived from mite feces. The results showed that (S)-(-)-blebbistatin O-benzoate inhibited the upregulation of these cytokines. Based on the above, (S)-(-)-blebbistatin O-benzoate has the potential to be developed as an atopic dermatitis treatment option that controls dermatitis symptoms by suppressing inflammation and improving barrier function by acting on multiple aspects of the pathogenesis of atopic dermatitis.

Pharmacotherapeutic strategies for Friedreich Ataxia: a review of the available data.

INTRODUCTION: Friedreich ataxia (FRDA) is a rare autosomal recessive disease, marked by loss of coordination as well as impaired neurological, endocrine, orthopedic, and cardiac function. There are many symptomatic medications for FRDA, and many clinical trials have been performed, but only one FDA-approved medication exists. AREAS COVERED: The relative absence of the frataxin protein (FXN) in FRDA causes mitochondrial dysfunction, resulting in clinical manifestations. Currently, the only approved treatment for FRDA is an Nrf2 activator called omaveloxolone (Skyclarys). Patients with FRDA also rely on various symptomatic medications for treatment. Because there is only one approved medication for FRDA, clinical trials continue to advance in FRDA. Although some trials have not met their endpoints, many current and upcoming clinical trials provide exciting possibilities for the treatment of FRDA. EXPERT OPINION: The approval of omaveloxolone provides a major advance in FRDA therapeutics. Although well tolerated, it is not curative. Reversal of deficient frataxin levels with gene therapy, protein replacement, or epigenetic approaches provides the most likely prospect for enduring, disease-modifying therapy in the future.

Slicing through silos: Development and evaluation of a hospital-based telehealth hepatitis C virus treatment program.

BACKGROUND: There exist many barriers to hepatitis C virus (HCV) treatment for those with substance use disorder (SUD) or who lack access to routine medical care. A hospital-based telehealth program was developed to provide treatment opportunities for hospitalized patients living with HCV. METHODS: This single site prospective cohort study conducted from July 2022 to March 2023 aimed to measure linkage to care with an HCV clinician and initiation of HCV treatment in hospitalized patients. Patients were assessed in-person by a social worker then seen via telehealth by a clinician who prescribed either glecaprevir/pibrentasvir or sofosbuvir/velpatasvir. Treatment was initiated with pharmacist assistance. The team conducted in-person and/or telephonic outreach during and after hospitalization. Cure was confirmed by sustained virologic response at 12 weeks (SVR12) post-treatment. RESULTS: A total of 25 patients were enrolled and completed telehealth visits. All patients had a history of SUD and 18 (72 %) were unstably housed. Nineteen patients (76 %) initiated treatment, and 14 (56 %) successfully completed treatment. Twelve patients (48 %) completed post-treatment labs, including two who prematurely discontinued treatment. Eleven patients (44 %) achieved confirmed cure with SVR12. CONCLUSION: A hospital-based, multidisciplinary telehealth program can be an innovative care model to successfully treat HCV in a difficult-to-treat patient populations.

Long-term outcomes of bictegravir/emtricitabine/tenofovir alafenamide as first-line therapy and as switch strategy in virologically suppressed persons with HIV: data from the ICONA cohort.

OBJECTIVES: To assess the effectiveness of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) among people poorly represented in clinical trials and potentially at higher risk of suboptimal response to ART. METHODS: Observational cohort study on persons with HIV (PWH) enrolled in ICONA who started BIC/FTC/TAF as initial therapy or as switching regimen while virologically suppressed. Primary endpoint was time to treatment failure (TF): new AIDS/death or virological failure (VF) or discontinuation for toxicity/failure. Secondary endpoints were time to treatment discontinuation for toxicity (TDT) and to VF. Groups of interest were those aged >50 years, female sex, and advanced HIV disease at first ART start. Probability of the events overall and according to groups and adjusted HR for every endpoint were calculated by Kaplan-Meier curves and Cox regression models. RESULTS: Nine hundred and thirty-three ART-naive and 1655 ART-experienced PWH initiated BIC/FTC/TAF. Over a median follow-up of 69.8 weeks, 89 (9.6%) PWH at their first regimen experienced TF. PWH aged >50 years had 1.83-fold (95% CI: 1.19-2.83) higher risk of TF; PWH with advanced HIV disease had 2.21-fold (95% CI: 1.53-3.82) higher risk; there were no differences in TF according to sex.Over a median follow-up of 146.3 weeks, 109 (6.6%) out of 1655 switching PWH experienced TF; no differences were found in the risk of TF, TDT and VF according to groups of interest. CONCLUSIONS: Overall, BIC/FTC/TAF is well tolerated and virologically effective in the real-world scenario for ART-naive and -experienced PWH. Older ART-naive PWH and those with advanced HIV disease may respond less well as the burden of diseases might compromise treatment efficacy.

Integrase strand transfer inhibitor resistance mediated by R263K plus E157Q in a patient with HIV infection treated with bictegravir/tenofovir alafenamide/emtricitabine: case report and review of the literature.

OBJECTIVES: The in vivo selection of E157Q plus R263K has not been reported in patients treated with coformulated bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF). To the best of our knowledge, we hereby report the first case of high-grade INSTI resistance associated with the presence of these aminoacidic substitutions in a treatment-experienced HIV patient treated with BIC/FTC/TAF. METHODS: Clinical case report and review of the literature. RESULTS: A heavily treatment-experienced patient was switched to BIC/FTC/TAF due to drug-drug interactions after being diagnosed with disseminated Mycobacterium avium-intracellulare disease. He had been treated before with raltegravir with poor adherence. No mutations in the integrase gene were detected 1 year after finishing treatment with raltegravir. Months after being switched to BIC/FTC/TAF, and again with poor adherence documented, virological failure (VF) was detected. The polymorphic substitution E157Q and the resistance mutation R263K in the integrase gene were detected, as well as M184V, among other mutations in the reverse transcriptase gene. The patient is currently being treated with dolutegravir q12h plus boosted darunavir along with directly observed treatment, and for the first time in 20 years, plasmatic viral load values are below 100 copies/mL. CONCLUSIONS: This case illustrates that the combination of E157Q and R263K plus M184V can be selected in vivo in a clinical scenario of poor adherence with BIC/FTC/TAF, although it is a very rare phenomenon. Previous VF with first-generation integrase strand transfer inhibitors (INSTIs) should be kept in mind when switching patients to second-generation INSTIs.

Bictegravir/emtricitabine/tenofovir alafenamide as first-line treatment in naïve HIV patients in a rapid-initiation model of care: BIC-NOW clinical trial.

OBJECTIVE: Multiple strategies have been utilised to reduce the incidence of HIV, including PrEP and rapid antiretroviral therapy initiation. The study objectives were to evaluate the efficacy, safety, satisfaction, treatment adherence, and system retention obtained with rapid initiation of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) in naïve patients. METHODS: This phase IV, multicenter, open-label, single-arm, 48-week clinical trial enrolled patients between January 2020 and June 2022. Adherence to treatment was evaluated with the SMAQ questionnaire and patient satisfaction with the EQ-5D. RESULTS: Two hundred eight participants were enrolled with mean age of 35.6 years; 87.6% were males; mean CD4 count was 393.5 cells/uL (<200 cells/uL in 22.1%); viral load log was 5.6 (VL>100 000 cop/mL in 43.3%); 22.6% had AIDS, and 4.3% were coinfected with HBV. BIC/FTC/TAF was initiated on the day of their first visit to the HIV specialist in 98.6% of participants, and 9.6% were lost to follow-up. The efficacy at week 48 was 84.1 % by intention-to- treat (ITT), 94.6% by modified ITT, and 98.3% by per protocol analysis. The regimen was discontinued in two subjects (0.9%) during week 1 for grade 3 adverse events. Treatment adherence (weeks 4 [90%, IQR: 80-99%] vs. 48 [90%, IQR: 80-95%; P = 0.49]) and patient satisfaction (weeks 4 [90%, IQR: 80-99%] vs. 48 [90%, IQR: 80-95 P = 0.49]) rates were very high over the 48- week study period. CONCLUSIONS: BIC/FTC/TAF is an appropriate option for rapid ART initiation in naïve HIV patients, offering high efficacy, safety, durability, treatment adherence, retention in the healthcare system, and patient satisfaction. Number Clinical Trial registration: NCT06177574.

Considerations for selecting second-line treatment in patients with progressive small cell lung cancer and the use of Lurbinectedin in this setting.

Small cell lung cancer (SCLC) is characterized by high initial responses to platinum-based chemotherapy plus immune checkpoint inhibitors; however, most patients quickly relapse and require subsequent treatment. Second-line treatment options in SCLC remain limited, and treatment algorithms are not completely consistent across the available guidelines in this setting. This review highlights key considerations regarding selection of second-line treatment for patients with relapsed SCLC. In particular, the role of lurbinectedin, which was first approved in 2020, representing the first significant addition to treatment algorithms in this setting for decades, is summarized. Future directions, including the identification of SCLC subtypes and the need for predictive biomarkers to guide patient selection and targeted therapy, are also discussed.

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.

Impact of social determinants of health on time to antiretroviral therapy initiation and HIV viral undetectability for migrants enrolled in a multidisciplinary HIV clinic with rapid, free, and onsite B/F/TAF: 'The ASAP study'.

OBJECTIVE: Multidisciplinary care with free, rapid, and on-site bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) dispensation may improve health outcomes among migrants living with HIV. However, models for rapid B/F/TAF initiation are not well studied among migrants living with HIV, and an understanding of how social determinants of health (SDH) may affect HIV-related health outcomes for migrants enrolled in such care models is limited. METHODS: Within a 96-week pilot feasibility prospective cohort study at a multidisciplinary HIV clinic, participants received free B/F/TAF rapidly after care linkage. The effects of SDH (i.e., birth region, sexual orientation, living status, education, employment, French proficiency, health coverage, use of a public health facility outside our clinic for free blood tests, and time in Canada) and other covariates (i.e., age, sex) on median time to antiretroviral therapy (ART) initiation and HIV viral undetectability from care linkage were calculated via survival analyses. RESULTS: Thirty-five migrants were enrolled in this study. Median time to ART initiation and HIV undetectability was 5 days (range 0-50) and 57 days (range 5-365), respectively. Those who took significantly longer to initiate ART were aged <35 years, identified as heterosexual, had less than university-level education, or were unemployed. No factor was found to significantly affect time to undetectability. CONCLUSION: Despite the provision of free B/F/TAF, several SDH were linked to delays in ART initiation. However, once initiated and engaged, migrants living with HIV reached HIV undetectability efficiently. Findings provide preliminary support for adopting this care model with migrants living with HIV and suggest that SDH should be considered when designing clinical interventions for more equitable outcomes.

Onasemnogene Abeparvovec Treatment after Nusinersen in an Infant with Spinal Muscular Atrophy Type 1.

BACKGROUND: Until recently, the treatment of spinal muscular atrophy (SMA) was limited to symptomatic treatment with no cure. Three innovative drugs, nusinersen, onasemnogene abeparvovec (OA), and risdiplam have been developed to treat SMA. Although the clinical trials for these drugs have demonstrated their efficacy, there is limited information on real world treatment strategies. In this study, we present a case of a male infant with SMA type 1 who underwent OA treatment after nusinersen treatment. CASE PRESENTATION: At 4 months of age, the patient was diagnosed with SMA type 1. At 6 months of age, nusinersen treatment was initiated. His motor function improved, but the effect was limited; therefore, his parents requested gene replacement therapy. During the preparation for OA treatment, anti-adeno-associated virus 9 (AAV9) antibody tests repeatedly showed non-specific reactions, which delayed initiation of treatment. The patient was put on ventilator management after he caught a common cold. During this management, the anti-AAV9 antibody test results were negative. Furthermore, the patient showed increased transaminase levels just before OA treatment; however, since these gradually decreased without signs of liver failure, we started OA treatment at 13 months of age. Four months later, the patient began to sit without support and was weaned from non-invasive positive pressure ventilation, although nasogastric tube feeding remained partially necessary. CONCLUSION: We believe that the management of unstable SMA type 1 symptoms, anti-AAV9 antibody testing, and changes in transaminase levels will be helpful for other patients with SMA who require treatment.

Real-life data of immune recovery using bictegravir/emtricitabine/tenofovir alafenamide in virologically suppressed people living with HIV. Results at 48-96†weeks of RETROBIC Study.

BACKGROUND: Switching strategy with bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) has become a gold standard for people living with HIV (PLWH), achieving high efficacy and safety rates. However, data regarding immune status in long-term real-life cohorts of pretreated patients are needed. METHODS: We performed a multicentre, non-controlled, retrospective study in virologically suppressed PLWH switching to B/F/TAF. We evaluated CD4+, CD8+ and CD4+/CD8+ ratio, efficacy and safety at weeks 48 and 96. RESULTS: The study comprised 1966 PLWH from 12 hospitals in Spain, of whom 80% were men, and the median age was 51.0 [42.0-57.0] years. The median time of HIV infection was 18.0 [10.0-27.0] years. No significant changes in CD4+, CD8+ T cells, or CD4+/CD8+ were observed after 96 weeks. Nevertheless, in women at weeks 48 and 96, we found a significant increase of CD4+ T cells and a significant decrease in CD8+ T cells. In patients ≥60 years at week 96, CD4 T cells significantly increased and CD8+ T cells significantly decreased at week 48. The on-treatment analysis revealed HIV-RNA <50 copies/mL in 95.6% (1700/1779) and 96.7% (1312/1356) of patients at weeks 48 and 96, respectively. The rates increased to 99.2% (1765/1779) and 99.7% (1352/1356) when considering HIV-RNA <200 copies/mL. No resistance mutations were detected in virologic failures. B/F/TAF discontinuations accounted for 10.2% (200). Simplification was the most common reason for discontinuation in 3.8% (74) of patients. CONCLUSION: In long-term virologically controlled PLWH, B/F/TAF achieved high efficacy rates and slightly improved immune status in women and individuals aged 60 and over after 48 and 96 of switching.

Effect of single-administration of D-sorbitol pretreatment on the bitterness and continued willingness to take asenapine: a randomized, single-blind, placebo-controlled, crossover trial.

BACKGROUND: Asenapine has unique orally-related side effects, such as a bitter taste induced by sublingual administration, which often results in discontinuation of the medication. While the FDA has approved black-cherry-flavored asenapine, several countries have prescribed only unflavored versions. Specifically, Asians commonly report experiencing the bitterness of asenapine because they are more sensitive to bitter tastes than other ethnic groups. In this study, with the aim of improving adherence by reducing the bitterness of asenapine, we investigated the effects of D-sorbitol, which reduced the bitterness parameters of taste sensors in our previous basic study on the bitterness and continuity of asenapine among patients with schizophrenia. METHODS: Twenty adult patients with schizophrenia were included in this single-blind, placebo-controlled, crossover trial. Participants rinsed their mouths with single-administration of D-sorbitol or a placebo prior to each administration of asenapine. We then conducted the questionnaires and assessed changes in the bitterness of asenapine (primary end point) and willingness to continue its use (secondary end point). RESULTS: D-sorbitol significantly improved the bitterness of asenapine (p = 0.038). Although it did not significantly increase the willingness to continue asenapine (p = 0.180), it did show improvement over the placebo in enhancing willingness to continue, especially in patients who were not accustomed to its taste. CONCLUSION: Our findings indicate that single-administration of D-sorbitol significantly reduces the bitterness of asenapine. In countries where flavored asenapine is not available, this finding could benefit patients who were not accustomed to its bitter taste. TRIAL REGISTRATION: This study was registered in the Japan Registry of Clinical Trials (jRCTs041210019) on May 14, 2021.

Bictegravir/Emtricitabine/Tenofovir Alafenamide in a Multicentre Cohort: Real-Life Experience From Spain.

BACKGROUND: The evaluation of bictegravir, emtricitabine, and tenofovir alafenamide (BIC/FTC/TAF) in clinical trials has shown high rates of virological suppression but information about its use in real-life settings is scarce. OBJECTIVE: To evaluate the effectiveness, safety, durability, and predictive variables of therapeutic failure of BIC/FTC/TAF in a real-life cohort. METHODS: This observational, retrospective, multicentered cohort study included treatment-naive (TN) and treatment-experienced (TE) adult patients living with HIV (PLWH) who started treatment with BIC/FTC/TAF from January 1, 2019, to January 31, 2022. Treatment effectiveness (based on intention-to-treat [ITT], modified ITT [mITT], and on-treatment [OT]), tolerability, and safety were evaluated in all patients who started BIC/FTC/TAF antiretroviral therapy. RESULTS: We included a total of 505 PLWH of whom 79 (16.6%) were TN and 426 (83.4%) were TE. Patients were followed up for a median (interquartile range [IQR]) of 19.6 (9.6-27.3) months, and 76% and 56% of PLWH reached month 6 and month 12 of treatment, respectively. Rates of TN PLWH with HIV-RNA <50 copies/mL in the OT, mITT, and ITT groups were 94%, 80%, and 62%, respectively, after 12 months of BIC/FTC/TAF treatment. Rates of TE PLWH with HIV-RNA <50 copies/mL were 91%, 88%, and 75% at month 12. The multivariate analysis revealed that neither age, sex, CD4 cell count <200 cells/µL, or viral load >100 000 copies/mL were associated with therapeutic failure. CONCLUSION AND RELEVANCE: Our real-life data showed that BIC/FTC/TAF is effective and safe for use in the treatment of both TN and TE patients in clinical practice.

Lumateperone for treatment of psychotic symptoms in Lewy body disease: A case report.

Individuals experiencing Lewy body disease (LBD) are particularly vulnerable to the adverse effects of neuroleptics. This sensitivity has been employed by some authorities as a diagnostic component for this disorder. At present, we do not have any Food and Drug Administration-approved antipsychotic for the management of psychotic symptoms in this condition. We present the first case of an LBD patient, showing favorable response in psychotic symptoms with lumateperone, a novel atypical neuroleptic. Our report revealed improvements in cognition, psychosis, and sleep following the initiation of lumateperone without concurrent emergence of extrapyramidal side effects, autonomic instability, parkinsonian features, or cognitive decline, which are typically seen when treated with available antipsychotic medications. Clinicians may wish to consider potential usefulness of lumateperone when managing patients with this disabling condition. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Rapid ART initiation with bictegravir/emtricitabine/tenofovir alafenamide in individuals presenting with advanced HIV disease (Rainbow study).

BACKGROUND: A rapid ART initiation approach can be beneficial in people with advanced HIV disease, in consideration of their high morbidity and mortality. The aim of our study was to evaluate the feasibility, efficacy and safety of rapid ART start with BIC/FTC/TAF in this setting. METHODS: Pilot, single-centre, single-arm, prospective, phase IV clinical trial conducted in a tertiary Italian hospital. Thirty ART-naïve people presenting with advanced HIV-1 diagnosis (defined as the presence of an AIDS-defining event and/or CD4 cell count <200 µL), were enrolled. Main exclusion criteria were active tuberculosis, cryptococcosis and pregnant/breastfeeding women. BIC/FTC/TAF was started within 7 days from HIV diagnosis. The primary endpoint was clinical or virologic failure (VF). Immunological parameters, safety, feasibility, neurocognitive performances and patient-reported outcomes were assessed as well. RESULTS: Over the study period, 40 (34%) of 116 patients diagnosed with HIV infection at INMI Spallanzani had advanced disease, of whom 30 (26%) were enrolled. The proportion of participants with HIV-RNA <50 cp/mL was 9/30 (30%) at week (w) 4, 19/30 (63%) at w12, 24/30 (80%) at w24, 23/30 (77%) at w36 and 27/30 (90%) at w48. Two unconfirmed VF occurred. No ART discontinuation due to toxicity or VF was observed. No ART modification was performed based on the review of genotype and no mutations for the study drugs were detected. Mean CD4 cells count changed by 133 cells/µL at BL to 309 cells/µL at w 48 and 83% of participants had a CD4 > 200 cells/µL at w 48. Two participants developed IRIS and one was diagnosed with disseminated TB and needed an ART switch. INTERPRETATIONS: Our results support the feasibility, efficacy and safety of BIC/FTC/TAF as a rapid ART strategy in patients with advanced HIV disease.

Health-related quality of life in patients aged 6-18 years with chronic hepatitis C treated with sofosbuvir/velpatasvir.

BACKGROUND & AIMS: The aim of this study was to assess the effect of treatment with sofosbuvir/velpatasvir (SOF/VEL) on the health-related quality of life (HRQL) of children with chronic hepatitis C. METHODS: In the non-commercial, non-randomized, open-label PANDAA-PED study, 50 children aged 6-18 years with chronic hepatitis C were treated with a fixed dose of SOF/VEL. All patients achieved sustained virologic response 12 weeks after the end of treatment (SVR12). Evaluation of HRQL was performed twice: at baseline (before the treatment) and during the SVR12 analysis using the KIDSCREEN-27 questionnaires, which included 5 dimensions of HRQL, for child self-reporting and parent proxy reporting. The normal range for the population was set to T values of 50 ± 10 points. Child-parent agreement was analysed using the intra-class correlation coefficient (ICC) and Bland-Altman test. RESULTS: Mean T values were within the normal range for all dimensions, both before and after treatment. There was a significant improvement in physical well-being based on the children's self-assessment (from 48.53 to 51.21, p = .03). In addition, a trend towards better scores in the 'social support & peers' part of the parent proxy evaluation (from 45.98 to 48.66, p = .06) was noticed. After the treatment, the proportion of children self-assessing their physical well-being as below normal significantly decreased from 17% to 5% (p = .007). HRQL scores were not associated with patients' sex, but in most cases, younger age correlated with better HRQL. Evaluation of the ICC for child self-reports versus parent proxy reports revealed poor to moderate agreement for most single measures. Bland-Altman analysis showed that in all dimensions, both before and after treatment, the limits of agreement (LoAs) exceeded ±5 points (half of the SD and considered a maximum allowed difference). CONCLUSIONS: A significant proportion of children with chronic hepatitis C have decreased HRQL in all dimensions, but effective treatment with SOF/VEL leads to an improvement in some areas of well-being. As the effect of HCV on HRQL is more pronounced in older patients, treatment of younger children should be indicated to prevent them from experiencing decreased HRQL due to ongoing HCV infection in the future.
