Reasons For Discontinuation Research Articles

Factors Associated with Time to Initial Antiretroviral Therapy Discontinuation in the DC Cohort.

When an initial antiretroviral therapy (ART) regimen is effective and well-tolerated, it can be maintained for years as long as the patient adheres. Prior research has revealed that shorter initial ART duration is associated with regimen type, female sex, injection drug use as the HIV transmission category, and lower baseline CD4 count. We examined potential factors associated with initial regimen discontinuation among a subset of newly diagnosed virally unsuppressed PWH in the DC Cohort, an ongoing prospective observation study that uses electronic health record data from clinic sites to collect relevant information, including demographic and clinical information. Participants were excluded from the analysis if they had less than 6 months of follow-up and were virally suppressed at enrollment. There were 479 individuals included in the study. The median age of participants was 33.9 years [interquartile range (IQR) 26-43.9]. The sample was predominantly male (79.1%) and of Black race (70.8%). Over half of the study participants (56.4%) attended community-based clinic sites. The median time to the discontinuation of initial ART was 2.7 years [95% confidence interval (CI): 2.3, 3.4]. Females had a shorter time to ART discontinuation [adjusted hazard ratio (aHR) 1.55, 95% CI: 1.14, 2.11] as did individuals who started on a protease inhibitor-based regimen versus integrase strand transfer inhibitors (aHR 1.87, 95% CI: 1.34, 2.61) and those receiving HIV care at a community-based site (aHR 1.46, 95% CI: 1.11,1.93). Although limited by lack of reason for discontinuation, we demonstrated that ART-naïve women, community clinic attendees, and patients starting on PIs had a shorter duration of initial ART. More anticipatory guidance may be needed to help patients stay on their initial therapy and manage the side effects or to be flexible in trying different regimens.

Efficacy and Safety of Brodalumab, an Anti-interleukin-17 Receptor A Monoclonal Antibody, for Palmoplantar Pustulosis: 16-Week Results of a Randomized Clinical Trial.

Palmoplantar pustulosis (PPP), a refractory skin disease characterized by repeated eruptions of sterile pustules and vesicles on palms and/or soles, involves interleukin-17 pathway activation. Brodalumab, a fully human anti-interleukin-17 receptor A monoclonal antibody, is being investigated for use in PPP treatment. The aim was to assess the efficacy and safety of brodalumab in Japanese PPP patients with moderate or severe pustules/vesicles. A phase 3, randomized, double-blind, placebo-controlled trial was conducted between July 2019 and August 2022, at 41 centers in Japan. Patients aged 18-70 years with a diagnosis of PPP for ≥24 weeks, a PPP Area Severity Index (PPPASI) score of ≥12, a PPPASI subscore of pustules/vesicles of ≥2, and inadequate response to therapy were included. Participants were randomized 1:1 to receive brodalumab 210 mg or placebo, subcutaneously (SC) at baseline, weeks 1 and 2, and every 2 weeks (Q2W) thereafter until week 16. Changes from baseline to week 16 in the PPPASI total score (primary endpoint) and other secondary skin-related endpoints and safety endpoints were assessed. Of the 126 randomized patients, 50 of 63 in the brodalumab group and 62 of 63 in the placebo group completed the 16-week period. Reasons for discontinuation were adverse event (n = 6), withdrawal by patient/parent/guardian (n = 3), progressive disease (n = 3), and lost to follow-up (n = 1) in the brodalumab group and Good Clinical Practice deviation (n = 1) in the placebo group. Change from baseline in the PPPASI total score at week 16 was significantly higher (p = 0.0049) with brodalumab (least-squares mean [95% confidence interval {CI}] 13.73 [10.91-16.56]) versus placebo (8.45 [5.76-11.13]; difference [95% CI] 5.29 [1.64-8.94]). At week 16, brodalumab showed a trend of rapid improvement versus placebo for PPPASI-50/75/90 response (≥50%/75%/90% improvement from baseline) and Physician's Global Assessment 0/1 score: 54% versus 24.2%, 36.0% versus 8.1%, 16.0% versus 0.0%, and 32.0% versus 9.7%, respectively. Infection was the dominant treatment-emergent adverse event (TEAE); the commonly reported TEAEs were otitis externa (25.4%/1.6%), folliculitis (15.9%/3.2%), nasopharyngitis (14.3%/4.8%), and eczema (14.3%/12.9%) in the brodalumab/placebo groups, respectively. The severity of most TEAEs reported was Grade 1 or 2 and less frequently Grade ≥3. Brodalumab SC 210 mg Q2W demonstrated efficacy in Japanese PPP patients. The most common TEAEs were mild infectious events. NCT04061252 (Date of Trial Registration: August 19, 2019).

Hand-foot syndrome in sorafenib and lenvatinib treatment for advanced thyroid cancer.

The aim of this study was to assess the clinical impact of hand-foot syndrome (HFS) during treatment with two multikinase inhibitors, sorafenib and lenvatinib, in a large group of patients with advanced thyroid cancer. Moreover, we looked for possible associations between HFS occurrence and clinical and pathological features. We retrospectively evaluated 239 patients with advanced thyroid cancer: 165 treated with lenvatinib and 74 with sorafenib. Statistical analyses were performed to verify which features could be correlated with HFS development. HFS was observed in 35/74 (47.4%) and in 43/165 (26.7%) patients treated with sorafenib or lenvatinib, respectively. The median latency from the drug beginning and HFS appearance was 27 days for sorafenib and 2.9 months for lenvatinib. G3/G4 toxicity was observed in 16/35 (45.7%) patients treated with sorafenib and only in 3/43 (7%) treated with lenvatinib. Drug dose reduction due to HFS was required in 19/74 (25.7%) and 3/165 (1.8%) patients treated with sorafenib and lenvatinib, respectively. HFS occurrence was significantly associated with a longer duration of therapy in both groups. HFS was a frequent adverse event during both lenvatinib and sorafenib therapy, with a higher frequency and toxicity grade during sorafenib treatment. HFS was the most frequent reason for drug reduction or discontinuation in patient treated with sorafenib. Early diagnosis of HFS is important to allow early intervention, possibly in a multidisciplinary setting, and to avoid treatment discontinuation, which is highly relevant to obtain the maximum effectiveness of systemic therapy.

Recurring disease activity in relapsing remitting multiple sclerosis: The multicenter RDA-RMS study

BackgroundThis study investigates the gap in understanding the dynamics of recurring disease activity (RDA) in RRMS patients after fingolimod (FGL) treatment discontinuation. The aim is to investigate RDA in RRMS patients after stopping FGL, aiming to improve management and comprehension of disease progression post-treatment. MethodsIn this multicenter, retrospective study, data from 172 of 944 RRMS patients aged 18–55, across nine centers in Turkey, who discontinued FGL treatment, were analyzed. The collected data included EDSS scores, annualized relapse rates (ARR), lymphocyte counts, and MRI findings, with follow-up assessments conducted at 6 months, 1 year, and up to 2 years. ResultsRDA was observed in 31.9 % of patients, with incidences of rebound and reactivation at 20.3 % and 11.6 %, respectively. Factors like younger age, longer treatment duration, lower lymphocyte counts, and higher lesion burden increased RDA risk. Notably, 52.9 % of pregnant patients experienced RDA (16.4 % of the overall RDA group), with rebound occurring in six and reactivation in three. Patients with RDA had longer medication-free intervals and increased ARR. Discontinuation reasons varied, with disease progression linked to a lower RDA risk. ConclusionFindings highlight the necessity for personalized management and vigilant monitoring after FGL discontinuation in RRMS patients, offering critical insights into RDA risk factors, and the complex interplay between treatment cessation, pregnancy, and disease progression.

Real-World Outcomes of Subsequent Chemotherapy after Progression Following Chemoradiation and Consolidative Durvalumab Therapy in Locally Advanced Non-small Cell Lung Cancer: An Exploratory Analysis from the CRIMSON Study (HOPE-005)

BackgroundThe optimal subsequent treatment strategy for locally advanced non-small cell lung cancer (LA-NSCLC) after chemoradiotherapy (CRT) and consolidative durvalumab therapy remains unknown. We aimed to determine the optimal subsequent treatment strategy for this clinical population. Materials and MethodsWe retrospectively enrolled 523 consecutive patients with LA-NSCLC treated with CRT and analyzed the treatment outcomes of subsequent therapy after progression following CRT and consolidative durvalumab therapy. Patients who received tyrosine kinase inhibitors as subsequent therapy were excluded. ResultsOut of 122 patients who received subsequent chemotherapy, 55% underwent platinum-based, 25% non-platinum-based, and 20% immune checkpoint inhibitor (ICI)-containing therapies. In the platinum-based group, patients with a durvalumab-progression-free survival (Dur-PFS) ≥ 1 year had a significantly longer median subsequent therapy-PFS (SubTx-PFS) than those with Dur-PFS < 1 year (13.2 months vs. 4.7 months; hazard ratio, 0.45; 95% confidence interval, 0.21–0.97; P = .04). Furthermore, among patients receiving non-platinum-based chemotherapy, the median SubTx-PFS was longer in the combined with angiogenesis inhibitor group than in the without group, although the difference was not statistically significant. No significant difference of SubTx-PFS was observed between the reason for durvalumab discontinuation and the outcomes of ICI-containing therapy. ConclusionIn clinical practice, platinum-based chemotherapy rechallenge is frequently employed following progression subsequent to CRT and consolidative durvalumab therapy for LA-NSCLC. Optimal treatment strategies may consider Dur-PFS and angiogenesis inhibitor feasibility. Further research is warranted to identify clinical biomarkers that can help identify patients who would benefit from ICI rechallenge.

Abatacept retention and clinical effectiveness in patients with rheumatoid arthritis in a real-world setting in Taiwan.

To evaluate real-world abatacept retention and clinical outcomes in patients with rheumatoid arthritis in Taiwan. This prospective, observational study enrolled patients with rheumatoid arthritis aged ≥20 years who received abatacept in real-world practice. The primary endpoint was the abatacept retention rate at 24 months. Patients were categorized into subgroups based on abatacept treatment status and previous biological disease-modifying antirheumatic drug (bDMARD) therapy. Risk factors affecting abatacept retention were determined by regression analysis. A total of 212 patients were enrolled. The overall abatacept retention rate at 24 months among all patients was 59.9% (95% confidence interval 53.0%-66.6%). Patients who were ongoing users of abatacept and bDMARD-naïve had the highest retention rate (76.3%); of these, 31.6% achieved low disease activity or remission after 2 years. Previous treatment with bDMARDs was associated with an increased risk of abatacept discontinuation (hazard ratio 1.99; p = .002). The most common reasons for abatacept discontinuation were drug switch (11.3%) and loss to follow-up (6.1%). Abatacept was well-tolerated with no new safety signals. The 24-month retention rate of abatacept was 59.9%; abatacept was associated with improved clinical outcomes and was well-tolerated in the real-world setting in Taiwan.

The Use of Semaglutide in Patients With Renal Failure-A Retrospective Cohort Study

ObjectiveSemaglutide, a glucagon-like peptide-1 receptor agonist is approved for weight loss and diabetes treatment, but limited literature exists regarding semaglutide use in patients with advanced chronic kidney disease (CKD). Therefore, this project assessed the safety and efficacy of semaglutide among patients with estimated glomerular filtration rate (eGFR) 15-29 mL/min/1.73 m2 (CKD stage 4), eGFR<15 mL/min/1.73 m2 (CKD stage 5) or on dialysis. MethodsThis is a retrospective electronic medical record based analysis of consecutive patients with advanced CKD (defined as CKD 4 or greater) who were started on semaglutide (injectable or oral). Data was collected between January 2018 and January 2023. Investigators verified CKD diagnosis and manually extracted data. Data were analyzed using Fisher’s exact test, paired t test, linear mixed effects models and Wilcoxon signed rank test. ResultsSeventy-six patients with CKD 4 or greater who initiated semaglutide were included. Most patients had a history of type 2 diabetes mellitus (96.0%), and most were males (53.9%). The mean age was 66.8 y (SD 11.5) with the mean body mass index was 36.2 (SD 7.5). The initial doses were 3 mg orally and 0.25 mg by injection. Maximum prescribed dose was 1 mg (injectable) in 28 (45.2%) patients and 14 mg (orally) in 2 (14.2%) patients. Patients received semaglutide for a median duration of 17.4 (IQR 0.43, 48.8) months. Forty-eight (63.1%) patients reported no adverse effects associated with the therapy. Mean weight decreased from 106.2 (SD 24.2) to 101.3 (SD 27.3) kg (P < .001). Eight patients (16%) with type 2 diabetes mellitus T2DM discontinued insulin after starting semaglutide. Mean hemoglobin A1c (HbA1c) decreased from 8.0% (SD 1.7) to 7.1% (SD 1.3) (P < .001). Adverse effects were the primary reason for semaglutide discontinuation (37.0%), with nausea, vomiting, and abdominal pain being the most common complaints. ConclusionsBased on this retrospective study semaglutide appears to be tolerated by most individuals with CKD 4 or greater despite associated gastrointestinal side effects similar to those observed in patients with better kidney function and leads to an improvement of glycemic control and insulin discontinuation in patients with T2DM. Modest weight loss (approximately 4.6% of the total body weight) was observed on the prescribed doses. Larger prospective randomized studies are needed to comprehensively assess the risks and benefits of semaglutide in patients with CKD 4 or greater and obesity.

Community pharmacists' experience, attitudes, and knowledge in providing care to lactating persons

AbstractIntroductionBreastfed infants have been shown to have a lower incidence of common childhood infections and sudden infant death syndrome. Furthermore, breastfeeding people experience lower rates of post‐partum mood disorders. The majority of breastfeeding people stop breastfeeding earlier than they intend. Concern about medication use during lactation is one reason for early discontinuation. It is critical that community pharmacists are prepared to appropriately counsel lactating patients on the effects medications can have on their efforts to breastfeed.ObjectivesTo (1) characterize community pharmacists' experience, attitudes, and knowledge regarding medication use during lactation and (2) identify factors impacting pharmacists' knowledge.MethodsA 52‐item electronic survey was used to collect demographics, experiences, attitudes, and knowledge regarding medication use during lactation. Community pharmacists who precepted for a Big Ten College of Pharmacy were eligible to participate in the study. Descriptive statistics were calculated using Microsoft Excel. Multivariable linear regression was performed using R (version 3.6.1) to evaluate which factors influenced total knowledge scores.ResultsForty‐eight of 1029 pharmacy preceptors (4.7%) completed the survey. The average total knowledge score for respondents was 51.3%. Most (80.0%) respondents agreed or strongly agreed they viewed themselves as valuable healthcare resources to breastfeeding patients. Most (82.5%) agreed or strongly agreed that patients who desire information about how medications can impact breastfeeding will directly ask for it. Fewer than 50% agreed or strongly agreed that pharmacy workflow supported them to look up lactation‐related information while working.ConclusionPharmacists have low knowledge of medications' effects on milk supply despite their positive attitudes towards breastfeeding and belief they are valuable healthcare resources to their breastfeeding patients. Workflow barriers, expectations that patients will ask for lactation‐related information if desired, and gaps in education may be key contributors to lactating patients not getting the information they need regarding medication use.

The most common contact lens-related complications: A brief review of the literature

Introducion and purpose Millions of people use contact lenses every day. Their primary and most common use is correcting refractive errors. Despite their beneficial purpose, contact lens use has many complications. It is estimated that 5 to 50% of patients may develop at least a single complication. The state of knowledge Contact lens-related complications are multifactorial. One of the main reasons for contact lens discontinuation is contact lens discomfort. Patients most often report dryness, burning, and irritated eyes. Other disorders can be briefly divided into conjunctival and corneal complications. The most common conjunctival and allergic complication of contact lens use is giant papillary conjunctivitis. Other significant conditions involving the conjunctiva can also be superior limbic keratoconjunctivitis or allergic or toxic conjunctivitis. Corneal complications, on the other hand, seemed to be much more severe. These include superficial punctate keratitis, peripheral corneal ulceration, and contact lens-related keratitis. Also, abrasion can occur due to improper eye hygiene or mechanical damage during lens replacement. It should also be remembered that prolonged use of lenses can lead to hypoxia and corneal edema. Summary This paper briefly outlines the possible complications of contact lens use. It is important to remember that despite their appropriate use, sometimes significant complications can occur. Noteworthy, corneal, or conjunctival complications require discontinuation of the lenses and appropriate treatment.

Local side effects during sublingual allergen-specific immunotherapy and pathogenetically based methods for their correction (Review)

Introduction. The study of the effectiveness and safety of allergen-specific immunotherapy remains relevant due to the emergence of a personalized approach in allergology and new dosage forms. Adverse reactions during sublingual allergen-specific immunotherapy are the leading reason of treatment discontinuation. Understanding the mechanisms of side effects and knowing how to overcome them allows us to achieve better tolerability of allergen-specific immunotherapy and maintain patient compliance.The aim of the review is to combine the available literature data on the frequency, nature, and pathogenetic basis of adverse events during sublingual allergen-specific immunotherapy and to consider options for their prevention and treatment.

Outcomes of patients with advanced solid tumors who discontinued immune-checkpoint inhibitors: a systematic review and meta-analysis

The outcome of patients with metastatic tumors who discontinued immune checkpoint inhibitors (ICIs) not for progressive disease (PD) has been poorly explored. We performed a meta-analysis of all studies reporting the clinical outcome of patients who discontinued ICIs for reasons other than PD. We searched PubMed, Embase and Scopus databases, from the inception of each database to December 2023, for clinical trials (randomized or not) and observational studies assessing PD-(L)1 and CTLA-4 inhibitors in patients with metastatic solid tumors who discontinued treatment for reasons other than PD. Each study had to provide swimmer plots or Kaplan-Meier survival curves enabling the reconstruction of individual patient-level data on progression-free survival (PFS) following the discontinuation of immunotherapy. The primary endpoint was PFS from the date of treatment discontinuation overall and according to tumor histotype, type of treatment and reason of discontinuation. The Combersure's method was used to estimate meta-analytical non-parametric summary survival curves assuming random effects at study level. Thirty-six studies (2180 patients) were included. The pooled median PFS (mPFS) was 24.7 months (95% CI, 18.8-30.6) and the PFS-rate at 12, 24, and 36 months was respectively 69.8% (95% CI, 63.1-77.3), 51.0% (95% CI, 43.4-59.8) and 34.0% (95% CI, 27.0-42.9). Univariable analysis showed that the mPFS was significantly longer for patients with melanoma (43.0 months), as compared with non-small cell lung cancer (NSCLC, 13.5 months) and renal cell carcinoma (RCC, 10.0 months; between-strata comparison test p-value < 0.001); for patients treated with anti-PD-(L)1+anti-CTLA-4 as compared with anti-PD-(L)1 monotherapy (44.6 versus 19.9 months; p-value <0.001), and in NSCLC when the reason of treatment discontinuation was elective as compared with toxicity onset (19.6 versus 4.8 months; p-value=0.003). The multivariable analysis confirmed these differences. The long-term outcome of patients who stopped ICIs for reasons other than PD was substantially affected by clinicopathological features: PFS after treatment discontinuation was longer in patients with melanoma, and/or treated with anti-PD-(L)1+anti-CTLA-4, and shorter in patients with RCC or in those patients with NSCLC who stopped treatment for toxicity onset.

Discontinuation of Palliative Brain Radiotherapy in Patients with Brain Metastases: A Case-Control Study.

Background: Discontinuation of radiotherapy is rarely discussed in the scientific literature. The goal of this study was, therefore, to estimate the frequency of and reasons for treatment discontinuations in patients receiving radiotherapy for brain metastases from solid tumors and to identify factors predicting said discontinuations. Methods: All patients treated for brain metastases from solid tumors between 2010 and 2020 at our institution were retrospectively reviewed. In addition to collecting relevant patient characteristics, the Recursive Partitioning Analysis (RPA) and disease-specific Graded Prognostic Assessment (GPA) groups for each patient were calculated to assess the performance of these scores in predicting treatment discontinuations. Results: Out of 468 patients who underwent cranial radiotherapy, 35 treatments (7.5%) were discontinued. The most frequent reason was clinical deterioration, which was documented in 26 (74.3%) of discontinued treatments. Patients whose radiotherapy was discontinued had, on average, more leptomeningeal disease (20.0% vs. 12.6%), worse ECOG performance status (mean ECOG performance status 1.86 vs. 1.39), and more uncontrolled extracranial metastases (85.3% vs. 70.8%). The frequencies of treatment discontinuation increased with worse prognosis and differed significantly across RPA groups (p = 0.037) but not across GPA groups (p = 0.612). Conclusions: Treatment discontinuation occurred in 7.5% of cases, mostly due to clinical deterioration. Poor performance status, as well as more advanced disease and, in turn, poor prognosis, were associated with higher discontinuation rates.

Analysis of Treatment Discontinuation in Orthokeratology: Studying Efficacy, Safety, and Patient Adherence Over Six Months.

This study aimed to evaluate the efficacy, safety, and participant compliance of orthokeratology treatment for the correction of myopic refractive errors over a six-month prospective study and to define the potential reasons for early treatment discontinuation. A total of 32 participants with low-to-moderate myopia were fitted with the spherical model of corneal refractive therapy (CRT) orthokeratology lenses (Paragon Vision Sciences) and followed over six months, with specific attention to alterations in refractive error, corneal topography, and epithelial thickness. Concurrently, participant feedback and reasons for any treatment discontinuation were documented. Significant changes in refractive error and in corneal topography were observed, with approximately 50% of the refractive error being corrected on the first night of use and 100% by the first two weeks ( P <0.001). Central epithelial thickness experienced substantial thinning, reducing to 15.65±4.49 μm (67.38%) ( P <0.001) after 6 months of lens use. Six participants withdrew from this study for varied reasons, including unmet visual expectations and difficulty adhering to the lens-wearing regimen. Notably, the dropout group exhibited higher baseline low-order aberrations and less prolate corneas than those who persisted with the treatment ( P <0.05). Orthokeratology with CRT is efficacious and safe for the correction of low-to-moderate myopia in adults, but a portion of patients discontinue the treatment in the first 6 months of contact lens wear. Special care should be taken when recommending orthokeratology in patients with higher levels of myopia and corneas with less prolate shape, providing more realistic expectations and even changing to dual axis or more sophisticated designs.

Thiazide Discontinuation in Chronic Kidney Disease Hypertension Management: A Retrospective Chart Review.

Thiazides are utilized in general hypertension management, however, their role in chronic kidney disease (CKD) hypertension management remains unclear. Although data support thiazide efficacy in advanced CKD, the adverse effect profile (including estimated glomerular filtration rate [eGFR] decline and electrolyte abnormalities) may lead to thiazide discontinuation. The authors assessed the thiazide discontinuation rate in Kaiser Permanente Southern California members with moderate-to-severe CKD and hypertension. This study was a multicenter retrospective analysis evaluating Kaiser Permanente Southern California members with hypertension and CKD 3B or 4 who filled a thiazide prescription in 2021, with follow-up through 2022. The outcomes were thiazide discontinuation rate, reason for thiazide discontinuation, time to thiazide discontinuation, and discontinuing practitioner specialty. Mean changes in blood pressure and eGFR from baseline were also evaluated. Of the 401 patients followed for 1 year after thiazide initiation, 65 patients discontinued a thiazide (discontinuation rate: 16.2%, mean time to discontinuation: 7.5 months). Of the 201 patients followed for 2 years after thiazide initiation, 57 patients discontinued a thiazide (discontinuation rate: 28.4%, mean time to discontinuation: 15.5 months). The most commonly documented thiazide discontinuation reason was increased serum creatinine (30% of total reasons at 1 year and 39% of total reasons at 2 years). Most patients with hypertension and CKD 3B or 4 continued on a thiazide with favorable blood pressure lowering effects and modest eGFR decline. Thiazides may be considered viable antihypertensive options with close renal function monitoring for patients with moderate-to-severe CKD.

Olokizumab in patients with inflammatory phenotype of osteoarthritis, treatment experience

Objective: to investigate the efficacy and safety of olokizumab (OKZ) in patients with knee osteoarthritis (OA) with synovitis, persistent pain and ineffectiveness of previous conservative therapy. Material and methods. The study included 15 patients with stage II–III knee OA who fulfilled the ACR criteria and had pain ≥50 mm on a visual analogue scale (VAS), synovitis and treatment failure. The age of patients ranged from 54 to 75 years; the duration of the disease was from 1 to 23 years. The duration of the study was 12 weeks, during which the patients received 3 subcutaneous injections of OKZ at a dose of 64 mg. The effectiveness of the treatment was assessed by the dynamics of pain intensity according to VAS, WOMAC and KOOS indices, the values of the DN4 questionnaire and the quality of life according to EQ-5D. In addition, the general assessment of the patient's health (GHA) according to VAS, the assessment of treatment efficacy by doctor and patient and the need for non-steroidal anti-inflammatory drugs (NSAIDs) were considered. All patients underwent laboratory testing. Results and discussion. During treatment, there was a significant decrease in pain intensity according to VAS, a statistically significant improvement in the KOOS and WOMAC indices (p&lt;0.05), quality of life according to the EQ-5D questionnaire and GHA. Patients and doctors rated the treatment results very positively: an improvement or significant improvement was observed in 92.3% of cases. Adverse events were identified in 4 patients, which in 2 cases served as the reason for discontinuation of OKZ treatment and termination of participation in the study. During treatment with OKZ, a statistically significant decrease in CRP and ESR values, an increase in the concentration of interleukin 6 (p = 0.003), COMP (p = 0.03) and PIINP (p = 0.01) were observed. Conclusion. The results obtained suggest a significant symptomatic and anti-inflammatory effect of OKZ in patients with the inflammatory phenotype of OA.

The cenobamate KORK study-A prospective monocenter observational study investigating cenobamate as an adjunctive therapy in refractory epilepsy, with comparisons to historical cohorts treated with add-on lacosamide, perampanel, and brivaracetam.

In Europe, cenobamate has been approved for use as an adjunctive therapy in adult patients with epilepsy (PWE) with focal-onset seizures (FOS) who have not responded satisfactorily to treatment with at least two antiseizure medications (ASMs). Pivotal trials and real-world observational studies have demonstrated a high efficacy of cenobamate, even in very difficult-to-treat epilepsies. Our aim was to investigate the efficacy of add-on cenobamate in adult PWE who were prospectively monitored. We compared these results with those previously obtained for add-on lacosamide, perampanel, and brivaracetam therapy. Patients were enrolled from the CENKORK study, which is a prospective, non-interventional, open-label, monocenter cohort study of adult PWE experiencing FOS. The titration of cenobamate was performed according to the guidelines outlined in the summary of product characteristics. The primary outcome measure was the retention rate at 6 months and 1 year. In addition, we assessed seizure-free rates, the proportion of patients achieving at least a 50% seizure reduction, adverse events, and the reasons for treatment discontinuation. These outcome measures were compared with historical controls treated with adjunctive lacosamide, perampanel, or brivaracetam at our center. Between June 2021 and 2022, 172 PWE with ongoing FOS were included. 22 cases were lost to follow-up, leaving 150 cases for the 1-year assessment. The retention rates at 6 months and 1 year were 88.7% and 80%, respectively. Seizure freedom was achieved in 14% of patients at both the 6-month and 1-year marks, while the ≥50% responder rates were 50% and 61%, respectively. The 6-month retention rate was significantly higher in cenobamate than in other ASMs (p < 0.001 for each comparator). Adverse events were significantly more common with perampanel (p < 0.001). Add-on cenobamate proved to be particularly efficacious compared to our experience with other recently introduced ASMs. This observational study was carried out in 172 adult patients with difficult-to-treat epilepsy who were treated with adjunctive cenobamate. After 1 year, the data of 150 patients could be analyzed. Seizure freedom, in the preceding 3 months, was achieved in 14%. The rate of PWE continuing cenobamate was 80%. In our hands, cenobamate showed promising efficacy and tolerability even when compared to other recently introduced antiseizure medications.

Multicentre service evaluation of injectable cabotegravir and rilpivirine delivery and outcomes across 12 UK clinics (SHARE LAI-net).

Long-acting injectable cabotegravir + rilpivirine (CAB + RPV LAI) was approved for use in virally suppressed adults in the England and Wales national health service in November 2021. We describe a service evaluation of delivery processes and outcomes in 12 clinics. Centres populated a database using information from local policies and clinical records. Services were asked to describe approval processes, clinic pathways, and adherence to national guidelines. Additional data were collected on reasons for regimen choice, treatment discontinuations, and management of viraemia. In total, 518 adults from 12 clinics were approved for CAB + RPV LAI between February 2022 and December 2023. Of the 518 people approved for CAB + RPV LAI, 423 received at least one injection. Median duration on CAB + RPV was 7.5 months (interquartile range 3.7-11.3). In total, 97% of injections were administered within the ±7-day window. Virological failure occurred in 0.7%, and 6% discontinued CAB + RPV. In this large UK-based cohort, robust approval processes and clinic protocols facilitated on-time injections and low rates of both discontinuation and virological failure.

Patient Adherence to a Real-World Digital, Asynchronous Weight Loss Program in Australia That Combines Behavioural and GLP-1 RA Therapy: A Mixed Methods Study.

Increasingly large numbers of people are using digital weight loss services (DWLSs) to treat being overweight and obesity. Although it is widely agreed that digital modalities improve access to care in general, obesity stakeholders remain concerned that many DWLSs are not comprehensive or sustainable enough to deliver meaningful health outcomes. This study adopted a mixed methods approach to assess why and after how long patients tend to discontinue Australia's largest DWLS, a program that combines behavioural and pharmacological therapy under the guidance of a multidisciplinary care team. We found that in a cohort of patients who commenced the Eucalyptus DWLS between January and June 2022 (n = 5604), the mean program adherence was 171.2 (±158.2) days. Inadequate supplying of a patient's desired glucose-like peptide-1 receptor agonist medication was the most common reason for discontinuation (43.7%), followed by program cost (26.2%), result dissatisfaction (9.9%), and service dissatisfaction (7.2%). Statistical tests revealed that ethnicity and age both had a significant effect on patient adherence. These findings suggest that DWLSs have the potential to improve access to comprehensive, continuous obesity care, but care models need to improve upon the one observed in the Eucalyptus Australia DWLS to mitigate common real-world program attrition factors.

Sodium phenylbutyrate-taurursodiol access, adherence and adverse event in patients with amyotrophic lateral sclerosis: Experience at one center in the United States.

Sodium phenylbutyrate-taurursodiol (PB-TURSO) was recently approved for treating amyotrophic lateral sclerosis (ALS). Third-party payors' coverage policies are evolving, and adverse events are just being fully assessed. The goals of this study were to evaluate patients' experiences in obtaining and continuing PB-TURSO and assess adverse events and medication adherence. Medical records of 109 ALS patients who were considered PB-TURSO candidates by the treating physician at a tertiary ALS clinic from October 2022 to May 2023 were reviewed. Data was recorded for demographics, clinical, and insurance information. A survey was e-mailed to patients asking about out-of-pocket expenses for PB-TURSO, financial assistance, medication start and (if applicable) stop dates, and reasons for discontinuation. Insurance information was available for 91 patients [57 males (62%); mean age 64.8 years (range 25.7-88)]. Of 79 who applied for insurance approval, 71 (90%) were approved; however, 19 required 1-3 appeals. Among 73 patients with available data about medication status, 54 started PB-TURSO and 19 did not, most commonly due to personal choice or out-of-pocket expenses. About 44% of patients (24/54) stopped taking PB-TURSO, primarily due to adverse events. Monthly out-of-pocket expenses varied from $0 to $3500 and 36 patients qualified for financial assistance. Administrative and nursing staff devoted 7.2 hours/week to the insurance authorization process. Most patients received insurance approval for PB-TURSO, but one-fourth required appeals. Some out-of-pocket costs were very high. Investment of staff time was substantial. These findings have implications for insurance coverage of, and adherence to, future ALS treatments.

Efficacy of post-lenvatinib treatments in patients (pts) with advanced renal cell carcinoma (aRCC).

4538 Background: Lenvatinib is a tyrosine kinase inhibitor (TKI) that targets both vascular endothelial growth factor (VEGF) receptor and fibroblast growth factor receptor. It has demonstrated efficacy both in the upfront and refractory disease settings. However, there is a lack of data surrounding the efficacy of TKIs post-lenvatinib exposure. In this study, we investigate the activity of post-lenvatinib therapies in pts with aRCC. Methods: We conducted a retrospective analysis utilizing the International Metastatic Database Consortium (IMDC). Pts having received treatment post lenvatinib exposure were eligible and divided into two cohort: pts post-1st line lenvatinib (2nd line cohort) and pts post-2nd line lenvatinib (3rd line cohort). The primary objective was objective response rate (ORR) and time to treatment failure (TTF). ORR was summarized with 95% two-sided exact binomial confidence interval. TTF was defined as time from treatment initiation to drug cessation for any reason censored at the date of last follow-up. Results: Overall, 84 pts received 1st line lenvatinib of whom 43 (51%) remain on therapy, 20 (24%) received 2nd line treatment, and 21 (25%) received no subsequent treatment. All pts received 1st line pembrolizumab + lenvatinib (ORR 50%, median TTF 9.7 months). Reason for lenvatinib discontinuation was progression (50%), progression + toxicity (20%), toxicity (15%), or other (15%). For the 2nd line cohort, median age was 61 years, most pts were male (85%), had prior nephrectomy (75%), clear cell histology (85%), and were IMDC intermediate/poor risk (55%). 2nd line therapy regimens included TKI monotherapy (80%), TKI-IO (5%), and other (15%). The ORR to 2nd line treatment was 5% (95% CI 0.2-25) and median TTF was 5.8 months (95% CI 1.9-14.9). Of 2nd line lenvatinib-exposed pts (n=84), 24 (29%) remain on treatment, 34 (40%) received 3rd line treatment, and 26 (31%) did not receive additional therapy. Most pts received 2nd line everolimus + lenvatinib (97%) (ORR 39%, median TTF 5.9 months). Reason for lenvatinib discontinuation was progression (59%), progression + toxicity (9%), toxicity (12%), or other (21%). For the 3rd line cohort, median age was 67 years, most pts were male (68%), had prior nephrectomy (88%), clear cell histology (68%), and were IMDC intermediate/poor risk (77%). 3rd line treatments included TKI alone (50%), IO-TKI (38%), and other (12%). The ORR to 3rd line treatment was 12% (95% CI 3.3-27) and median TTF was 2.8 months (95% CI 1.9-7.4). Conclusions: In this analysis, we demonstrate modest activity of TKI-based therapy post-lenvatinib exposure. Our study highlights the need for improved treatment options for pts progressing on lenvatinib-based therapies.
