Comorbidities are not associated with pain symptom or recurrence in patients with pilonidal disease.

BACKGROUND: Comorbidities can potentially impact the presentation or outcome of patients with pilonidal disease (PD) due to poor wound healing or increased inflammatory response. We hypothesized that certain comorbidities could lead to worse pain or higher recurrence rate. METHODS: A retrospective study was performed on all PD patients treated with standardized minimally invasive protocol at our clinic 2019-2022. Patients' demographics, comorbidities, initial/follow-up pain score, pain duration, and recurrence were recorded. Data were analyzed by t test and Chi-square test. RESULTS: Of 207 total PD patients (108 male, 99 female), 61 had comorbidities. Mean age was 18.2 years. The recurrence rate was 7%, and patients with recurrence were significantly younger. Associated comorbidities included mood/psychiatric disorders (31%), asthma/respiratory illness (30%), obesity-related illness (15%), gastrointestinal disorders (13%), diabetes (10%), thyroid disease (8%), cardiac disease (8%), musculoskeletal/connective tissue disorders (7%), immunologic disease (7%), inflammatory bowel disease (5%), and chest wall disorders (3%). The presence of comorbidities was not associated with PD recurrence. By dividing patients into adolescents (< 18 years) and adults (≥ 18 years), we found no association between comorbidity and recurrence in either group. 55% of patients had pain as an initial symptom. The initial pain score, pain duration, and pain score at follow-up were not associated with comorbidities. The comorbidities and recurrence were not associated with patient age or sex. CONCLUSIONS: Having comorbidities was not associated with pain symptoms or recurrence in PD patients. Even though patients with recurrence were younger, there was no association between comorbidity and recurrence in either adolescents or adults.

A standardized treatment protocol for pilonidal disease can influence the health mindset of adolescents.

PURPOSE: Pilonidal disease (PD) significantly impacts patients' quality of life and requires regular maintenance behaviors to achieve cure. Health mindset is a psychological construct which can influence health behaviors and outcomes, with a growth mindset being associated with better outcomes than a fixed. We propose that participation in a standardized treatment protocol can affect the health mindset for adolescents with pilonidal disease. METHODS: PD patients' demographics, recurrence, and comorbidities were prospectively collected from 2019 to 2022. We assessed patients' mindset score at initial presentation using the validated Three-Item Mindset Scale (1-6) then reassessed during follow-up. t-test was used to compare baseline and follow-up mindset scores and stratified by recurrence or comorbidities. p ≤ 0.05 was considered significant. RESULTS: A total of 207 PD patients (108 males, 99 females) with mean age 18.2 ± 3.7 years were followed for 351 ± 327 days. Mean baseline mindset score (4.76 ± 1.27) was significantly lower than mean follow-up mindset score (5.03 ± 1.18, p = 0.049). Baseline mindset score was significantly lower among patients with PD recurrence (4.00 ± 0.66) compared to those without recurrence (4.8 ± 1.29, p = 0.05). Among patients with PD recurrence, mean baseline mindset score (4.00 ± 0.66) was significantly lower than mean follow-up mindset score (5.27 ± 0.93, p = 0.0038). Patient comorbidity did not affect the baseline or follow-up mindset score. CONCLUSIONS: Participation in a standardized treatment protocol is associated with the development of a stronger growth mindset over time for patients with PD. Furthermore, a growth mindset was linked to lower recurrence rate than a fixed mindset. Further investigations into how treatment approaches can work in concert with health mindset are proposed.

Regular epilation alone is an acceptable treatment for symptom-free pilonidal patients.

INTRODUCTION: Patients with mild pilonidal disease often experience symptom resolution without excision. We hypothesized that treating symptom-free/asymptomatic pilonidal patients with regular epilation alone had similar recurrence rate as patients who were also treated surgically. METHOD: Patient data were prospectively collected 2/2019-11/2022 at our Pilonidal Clinic. All patients received regular epilation; all patients presented before 12/2020 also underwent pit excision using trephines. Starting 1/2021, only symptomatic patients underwent pit excision; symptom-free patients at presentation received only regular epilation. Recurrence rates were statistically analyzed. RESULTS: 255 patients (male:54.4%, female:45.6%), median age 17.3years (IQR:15.8-19.1) were followed for median 612.5days (IQR:367.5-847). 44.1% identified as Hispanic, 36.5% Caucasian, 17.1% Asian, 2.4% Black. Median symptom duration at presentation was 180.5days (IQR:44.5-542.5). 160 patients were initially treated with surgical excision and regular epilation, while 95 patients with regular epilation only. The failure rate between patients who received surgical excision initially and recurred (9.4%) and patients who received epilation only and recurred (12.6%) was similar, after controlling for sex, race, age, comorbidities, skin type, hair color, hair thickness (p > 0.05). Patients who recurred after only undergoing regular epilation all underwent surgical excision, median 100days (IQR:59.5-123.5) after initial presentation. CONCLUSION: Regular epilation alone is an acceptable treatment for symptom-free pilonidal patients.

Serum tau protein elevation in migraine: a cross-sectional case-control study.

BACKGROUND: Migraine is a disorder associated with neuropeptide release, pain and inflammation. Tau protein has recently been linked to inflammatory diseases and can be influenced by neuropeptides such as CGRP, a key neurotransmitter in migraine. Here, we report serum concentrations of total-tau protein in migraine patients and healthy controls. METHODS: In this cross-sectional study, interictal blood samples from n = 92 patients with episodic migraine (EM), n = 93 patients with chronic migraine (CM), and n = 42 healthy matched controls (HC) were studied. We assessed serum total-tau protein (t-tau) and for comparison neurofilament light chain protein (NfL), glial fibrillary acidic protein (GFAP), and ubiquitin carboxy-terminal hydrolase L (UCH-L1) concentrations using the Neurology 4-plex kit, on a single molecule array HD-X Analyzer (Quanterix Corp Lexington, MA). Matched serum/cerebrospinal fluid (CSF) samples were used for post-hoc evaluations of a central nervous system (CNS) source of relevant findings. We applied non-parametric tests to compare groups and assess correlations. RESULTS: Serum t-tau concentrations were elevated in EM [0.320 (0.204 to 0.466) pg/mL] and CM [0.304 (0.158 to 0.406) pg/mL] patients compared to HC [0.200 (0.114 to 0.288) pg/mL] (p = 0.002 vs. EM; p = 0.025 vs. CM). EM with aura [0.291 (0.184 to 0.486 pg/mL); p = 0.013] and EM without aura [0.332 (0.234 to 0.449) pg/mL; p = 0.008] patients had higher t-tau levels than HC but did not differ between each other. Subgroup analysis of CM with/without preventive treatment revealed elevated t-tau levels compared to HC only in the non-prevention group [0.322 (0.181 to 0.463) pg/mL; p = 0.009]. T-tau was elevated in serum (p = 0.028) but not in cerebrospinal fluid (p = 0.760). In contrast to t-tau, all proteins associated with cell damage (NfL, GFAP, and UCH-L1), did not differ between groups. DISCUSSION: Migraine is associated with t-tau elevation in serum but not in the CSF. Our clinical study identifies t-tau as a new target for migraine research.

Orchestrating a New Path for Multiple Sclerosis: Achieving Physical, Cognitive, and Emotional Rehabilitation Goals Through Physical and Music Therapy.

BACKGROUND: Interdisciplinary therapies for the management of people with multiple sclerosis (MS) are underappreciated. There is an urgent need to introduce music therapy (MT), either alone or in combination with physical therapy (PT), into clinical practice to achieve synergy with disease-modifying therapies. A holistic approach to rehabilitation for people with MS may mitigate symptoms and reduce polypharmacy, potentially lowering health care costs. RESULTS: As MS progresses, patients experience a range of worsening symptoms, and many develop psychosocial comorbidities. As disease-modifying therapies delay disability progression, nonpharmacologic treatments become increasingly important. The main aim of PT is to improve or maintain patients' functional mobility, strength, and flexibility. Because it targets multiple functions, MT can help improve functional and psychosocial domains and may be a valuable intervention to help patients achieve the physical, cognitive, and emotional goals of PT. Exploratory studies showed that MT, alone or in combination with PT, can lead to functional improvements in mobility, balance, gait, and fatigue. Similar to PT, MT also has benefits in improving fine motor skills, cognition, learning, and memory and in providing emotional support. CONCLUSIONS: Both MT and PT have the potential to improve overall well-being and health-related quality of life in physically active patients with MS, and MT can provide added emotional support for those who are less able to engage in physical activity. However, MT is not typically a part of standard of care, and PT visits are limited. Nevertheless, interdisciplinary therapies should be incorporated into clinical practice.

Effects of baseline age and disease duration on the efficacy and safety of siponimod in patients with active SPMS: Post hoc analyses from the EXPAND study.

BACKGROUND: Older age and longer disease duration (DD) may impact the effectiveness of disease-modifying therapies in patients with multiple sclerosis (MS). Siponimod is a sphingosine 1-phosphate receptor modulator approved for the treatment of active secondary progressive MS (SPMS) in many countries. The pivotal phase 3 EXPAND study examined siponimod versus placebo in a broad SPMS population with both active and non-active disease. In this population, siponimod demonstrated significant efficacy, including a reduction in the risk of 3-month confirmed disability progression (3mCDP) and 6-month confirmed disability progression (6mCDP). Benefits of siponimod were also observed across age and DD subgroups in the overall EXPAND population. Herein we sought to assess the clinical impact of siponimod across age and disease duration subgroups, specifically in participants with active SPMS. METHODS: This study is a post hoc analysis of a subgroup of EXPAND participants with active SPMS (≥ 1 relapse in the 2 years before the study and/or ≥ 1 T1 gadolinium-enhancing magnetic resonance imaging lesion at baseline) receiving oral siponimod (2 mg/day) or placebo during EXPAND. Data were analyzed for participant subgroups stratified by age at baseline (primary cut-off: < 45 year ≥ 45 years; and secondary cut-off: < 50 years or ≥ 50 years) and by DD at baseline (< 16 years or ≥ 16 years). Efficacy endpoints were 3mCDP and 6mCDP. Safety assessments included adverse events (AEs), serious AEs, and AEs leading to treatment discontinuation. RESULTS: Data from 779 participants with active SPMS were analyzed. All age and DD subgroups had 31-38% (3mCDP) and 27-43% (6mCDP) risk reductions with siponimod versus placebo. Compared with placebo, siponimod significantly reduced the risk of 3mCDP in participants aged ≥ 45 years (hazard ratio [HR]: 0.68; 95% confidence interval [CI]: 0.48-0.97), < 50 years (HR: 0.69; 95% CI: 0.49-0.98), ≥ 50 years (HR: 0.62; 95% CI: 0.40-0.96), and in participants with < 16 years DD (HR: 0.68; 95% CI: 0.47-0.98). The risk of 6mCDP was significantly reduced with siponimod versus placebo for participants aged < 45 years (HR: 0.60; 95% CI: 0.38-0.96), ≥ 45 years (HR: 0.67; 95% CI: 0.45-0.99), < 50 years (HR: 0.62; 95% CI: 0.43-0.90), and in participants with < 16 years DD (HR: 0.57; 95% CI: 0.38-0.87). Increasing age or longer MS duration did not appear to increase the risk of AEs, with an observed safety profile that remained consistent with the overall active SPMS and overall SPMS populations in EXPAND. CONCLUSIONS: In participants with active SPMS, treatment with siponimod demonstrated a statistically significant reduction in the risk of 3mCDP and 6mCDP compared with placebo. Although not every outcome reached statistical significance in the subgroup analyses (possibly a consequence of small sample sizes), benefits of siponimod were seen across a spectrum of ages and DD. Siponimod was generally well tolerated by participants with active SPMS, regardless of baseline age and DD, and AE profiles were broadly similar to those observed in the overall EXPAND population.

Increasing Amount of Hair Reduction using Laser Correlates with Lower Probability of Recurrence in Patients with Pilonidal Disease.

BACKGROUND: Hair at the gluteal cleft plays a key role in the development and recurrence of pilonidal disease (PD). We hypothesized that more hair reduction achieved using laser could correlate with lower chance of PD recurrence. METHODS: PD patients who underwent laser epilation (LE) were categorized by Fitzpatrick skin type, hair color, and hair thickness. Photos taken at LE sessions were compared to determine hair reduction amount. LE sessions completed prior to the recurrences were recorded. Groups were compared using multivariate T-test. RESULTS: 198 PD patients had mean age 18.1 ± 3.6 years. 21, 156, and 21 patients had skin types 1/2, 3/4, and 5/6, respectively. 47 patients had light- and 151 had dark-colored hair. 29 patients had fine hair, 129 medium, and 40 thick. Median follow-up was 217 days. 95%, 70%, 40%, and 19% of patients reached 20%, 50%, 75%, and 90% hair reduction after mean LE sessions of 2.6, 4.3, 6.6, 7.8 sessions, respectively. To reach 75% hair reduction, patients require a mean of 4.8-6.8 LE sessions, depending on different skin/hair characteristics. PD recurrence rate was 6%. Probability of recurrence after 20%, 50%, 75% hair reduction was decreased by 50%, 78%, 100%, respectively. Dark hair and skin type 5/6 were associated with higher recurrence rates. CONCLUSION: Patients with dark-color and thick hair require more LE sessions to achieve certain degree of hair reduction. Patients with dark hair and skin type 5/6 were more likely to recur; more hair reduction correlated with lower chance of recurrence. LEVEL OF EVIDENCE: Level IV.

Outcome assessment of office Plastibell circumcision in infants utilizing interactive electronic health record.

OBJECTIVE: To assess the outcomes of office-based circumcision performed using Plastibell devices in infants, utilizing the MyChart interactive electronic health record (iEHR) system to monitor the progress and identify potential complications. METHODS: This is a prospective cohort study conducted between March 2021 to April 2022 on all infants undergoing office based Plastibell circumcision. Parents were encouraged to submit concerns via MyChart and to submit photos if the ring has not fallen by post-procedure day 7. Telehealth or in-person clinic visits were then made accordingly. Postoperative complications were collected and compared with existing literature. RESULTS: Of the 234 consecutive infants, the average age was 33 days (9-126 days) and the average weight was 4.35 kg (2.5-7.25 kg). A total of 170 parents (73%) responded to MyChart messages. Fourteen (6%) complications necessitating local intervention were identified: excessive fussiness (1), bleeding (2), ring retention (11) including 2 incomplete skin division requiring repeat dorsal block and surgical completion, fibrinous adhesion (3), and proximal ring migration (6). The photo and messages submitted through iEHR facilitated early patient return for intervention. Additionally, 17 parents submitted photos which were expected postprocedural findings and were reassured through iEHR, thus omitting unnecessary return visits. The 2 patients with incomplete skin division occurred early in the series using the included cotton ties. Subsequent procedures were performed with double 0-Silk ties (n = 218) without similar finding. CONCLUSION: The interactive utilization of iEHR communication in the post-circumcision period identified proximal bell migration and bell trapping, allowed earlier intervention and reduced complications. LEVEL OF EVIDENCE: Level 1.

Adoption of a standardized treatment protocol for pilonidal disease leads to low recurrence.

BACKGROUND: Pilonidal disease may present as acute abscesses or chronic draining sinuses. There is no standardized treatment and recurrence rates can be as high as 30%. Within our five-hospital network we have established a standardized treatment protocol including minimally invasive surgical trephination and aggressive epilation. We hypothesize that such a treatment protocol can be established across different hospital settings and lead to low overall recurrence. METHODS: Patients with pilonidal disease were enrolled in the study on presentation to our hospital network. Those that underwent initial surgery outside our hospital system or were noncompliant with our treatment protocol were excluded. Patients were grouped based on surgeon and treating facility. Frequency of recurrence per surgeon and per hospital was calculated and compared. RESULTS: Out of 132 patients, 80 patients were included (45 female, 35 male) while 52 were excluded because of initial surgery at a non-network hospital or for protocol noncompliance. Median age was 17 (16-19) years and median length of follow-up was 352 (261-496) days. There were 6 patients who experienced at least one recurrence. There was an overall 8% recurrence rate with no significant difference noted between surgeons or hospitals (p = 0.15, p = 0.64, respectively). CONCLUSIONS: We have successfully implemented a standardized treatment protocol for pilonidal disease across different hospital settings and by different surgeons, with an overall low recurrence rate. Our findings suggest that adoption of a standardized protocol for treatment of pilonidal disease can lead to low recurrence. LEVEL OF EVIDENCE: Level IV.

A phase 3, randomised, placebo-controlled study of erenumab for the prevention of chronic migraine in patients from Asia: the DRAGON study.

ABSTACT: BACKGROUND: DRAGON was a phase 3, randomised, double-blind, placebo-controlled study which evaluated the efficacy and safety of erenumab in patients with chronic migraine (CM) from Asia not adequately represented in the global pivotal CM study. METHODS: DRAGON study was conducted across 9 Asian countries or regions including mainland China, India, the Republic of Korea, Malaysia, the Philippines, Singapore, Taiwan, Thailand, and Vietnam. Patients (N = 557) with CM (aged 18-65 years) were randomised (1:1) to receive once-monthly subcutaneous erenumab 70 mg or matching placebo for 12 weeks. The primary endpoint was the change in monthly migraine days (MMD) from baseline to the last 4 weeks of the 12-week double-blind treatment phase (DBTP). Secondary endpoints included achievement of ≥ 50% reduction in MMD, change in monthly acute headache medication days, modified migraine disability assessment (mMIDAS), and safety. Study was powered for the primary endpoint of change from baseline in MMD. RESULTS: At baseline, the mean (SD) age was 41.7 (± 10.9) years, and 81.5% (n = 454) patients were women. The mean migraine duration was 18.0 (± 11.6) years, and the mean MMD was 19.2 (± 5.4). 97.8% (n = 545) randomised patients completed the DBTP. Overall, demographics and baseline characteristics were balanced between the erenumab and placebo groups except for a slightly higher proportion of women in the placebo group. At Week 12, the adjusted mean change from baseline in MMD was - 8.2 days for erenumab and - 6.6 days for placebo, with a statistically significant difference for erenumab versus placebo (adjusted mean difference vs placebo: - 1.57 [95%CI: - 2.83, - 0.30]; P = 0.015). A greater proportion of patients treated with erenumab achieved ≥ 50% reduction in MMD versus placebo (47.0% vs 36.7%, P = 0.014). At Week 12, greater reductions in monthly acute headache medication days (- 5.34 vs - 4.66) and mMIDAS scores (- 14.67 vs - 12.93) were observed in patients treated with erenumab versus placebo. Safety and tolerability profile of erenumab was comparable to placebo, except the incidence of constipation (8.6% for erenumab vs 3.2% for placebo). CONCLUSION: DRAGON study demonstrated the efficacy and safety of erenumab 70 mg in patients with CM from Asia. No new safety signals were observed during the DBTP compared with the previous trials. TRIAL REGISTRATION: NCT03867201.

CRLF2 Gene in B-cell Acute Lymphoblastic Leukemia.

OBJECTIVES: B-cell acute lymphoblastic leukemia (B-ALL) is a subset of ALL that comprises 75% of ALL cases. There are a variety of chromosome aneuploidy or chromosomal rearrangements implicated in B-ALL. Deregulation of CRLF2 expression is seen in 5-15% of B-ALL patients and occurs primarily via a reciprocal translocation with immunoglobulin heavy chain (IGH), rearrangements of CRLF2, deletion within the PAR1 region of the X and Y chromosomes, and CRLF2 mutations as well as mutations of the CRLF2-involved pathways and are seen in Ph-like B-ALL. They are associated with a poor prognosis. Blinatumomab is an available immunotherapy, and there are currently a few ongoing clinical trials to treat CRLF2 B-ALL. This review focuses on the role of CRLF2 in B-ALL and summarizes the literature regarding its molecular pathways, clinical significance, incidence rates across demographics, therapies, and areas of further research.

Burden of pilonidal disease and improvement in quality of life after treatment in adolescents.

PURPOSE: Pilonidal Disease (PD) affects adolescents in different aspects. We hypothesized that patients with different gender, ethnicity, and age have different quality of life (QOL) measurements which could improve with minimally invasive treatment (MIT). METHODS: 131 PD patients underwent MIT (laser epilation ± trephination) from 2019 to 2021. Patients' demographics were recorded. Before and after MIT, patients received QOL questionnaire consisting of four categories: daily activities, sports participation, school/work attendance, and socializing. Data were analyzed using Student and multivariate t test. P < 0.05 was considered statistically significant. RESULTS: 101 (51 male, 50 female) patients were included. 30 patients with incomplete data were excluded. 54% of patients were < 18 years old. 47.5% were Hispanic. Median symptom duration prior to presentation was 5.4 (1.3-15) months. Prior to MIT, patients' ability to perform daily activities, participate in sports, attend school/work, and socialize was moderately or severely impacted in 66%, 57%, 45%, and 23% of respondents, respectively; after MIT, only 7%, 8%, 2%, and 4% were affected (p < 0.01). Recurrence rate was 6%. Pre-MIT, older patients and non-Hispanics reported worse impact on their QOL. Symptom duration or PD recurrence did not correlate with patient's pre- or post-MIT QOL. CONCLUSION: Patients' ethnicity and age impacted QOL in PD. All patients' QOL significantly improved with MIT. Considering the importance of socializing, playing sports, and school/work attendance in adolescents, our study highlights importance of early treatment of PD.

A Patient with Myxoid/Round Cell Liposarcoma (MRCL) Involving the Well-known Translocation t(12;22): A Case Report with the Cytogenomic Landscape of this Rearrangement.

OBJECTIVES: Myxoid/Round Cell Liposarcoma (MRCL) is characterized as a soft tissue sarcoma that is associated with unusual patterns of metastasis to extrapulmonary sites, such as bones and other soft tissue sites. Here, we present a case of a 48-year-old male patient, diagnosed with MRCL. The patient presented with a grade 1 myxoid liposarcoma in his left leg. DNA FISH analysis showed variant rearrangements of the EWSR1 (22q12) gene and loss of the 5' DDIT3 (CHOP 12q13) gene. The variant rearrangement showed one or two fusions with multiple separated (rearranged) signals. The EWSR1-DDIT3 rearrangement has been reported in MRCL. The variant rearrangements of the EWSR1 (22q12) gene findings correlate with concurrent conventional cytogenetic findings and were described as nuc ish(EWSR1x2) (5'EWSR1 sep 3'EWSR1x1)[128/100],(5'EWSR1,3'EWSR1)x1~3(5'EWSR1 con 3'EWSR1x1~2)[57/100]. The variant rearrangements of the DDIT3 (CHOP 12q13) gene findings were described as nuc ish(5'DDIT3x1,3'DDIT3x2)(5'DDIT3 con 3'DDIT3x1)[195/200]. Molecular cytogenetic studies also showed a rearrangement of EWSR1 (22q12) in 64% of nuclei and variant rearrangement in 31.5% of nuclei. A loss of DDIT3's (12q13) 5' signal was found in 97.5% of interphase nuclei. Molecular pathology results indicated the patient was positive for EWSR1 (exon 7) and DDIT3 (exon 2) fusion. The patient underwent radiation therapy pre-resection of the myxoid liposarcoma. The most common form of MRCL is associated with t(12;16)(q13;p11), leading to FUS-CHOP and EWS-CHOP fusion proteins acting as aberrant transcription factors. The key element here is that this EWSR1-DDIT3 rearrangement led to a translocation t(12;22)(q13;q12) which is a rare cytogenetic event that led to the development of MRCL in this patient.

Prognostic Value of Serum Neurofilament Light Chain for Disease Activity and Worsening in Patients With Relapsing Multiple Sclerosis: Results From the Phase 3 ASCLEPIOS I and II Trials.

Objective: This study aims to confirm the prognostic value of baseline serum neurofilament light chain (sNfL) for on-study disease activity and worsening in patients with relapsing MS (RMS). Background: Previous post-hoc studies suggested that sNfL could be a prognostic biomarker in RMS. In the phase 3 ASCLEPIOS I/II trials in which ofatumumab demonstrated better efficacy outcomes than teriflunomide, treatment with ofatumumab also led to significantly reduced sNfL levels compared to teriflunomide treatment. Design/Methods: In this study, we report protocol-planned analyses from the pooled ASCLEPIOS I/II trials (N=1882). Per protocol, patients were stratified by median baseline sNfL levels (9.3 pg/ml) into high (>median) and low (≤median) categories to prognosticate: annualized rate of new/enlarging T2 (neT2) lesions in year 1 and 2, annualized relapse rate, annual percentage change in whole brain (WB) and regional brain volume [thalamus, white matter (WM), cortical gray matter (cGM)], and disability outcomes. Similar analyses were performed for the recently diagnosed (within 3 years), treatment-naive patients (no prior disease-modifying therapy) subgroup. Results: High versus low sNfL at baseline was prognostic of increased on-study T2 lesion formation at year 1 (relative increase: ofatumumab +158%; teriflunomide +69%, both p<0.001), which persisted in year 2 (+65%, p=0.124; +46%, p=0.003); of higher annual percentage change of WB volume (ofatumumab, -0.32% vs. -0.24%, p=0.044, and teriflunomide, -0.43% vs. -0.29%, p=0.002), thalamic volume (-0.56% vs. -0.31%, p=0.047 and -0.94% vs. -0.49%, p<0.001), and WM volume (-0.30% vs. -0.19%, p=0.083 and -0.38% vs. -0.18%, p=0.003) but not of cGM volume (-0.39% vs. -0.32%, p=0.337 and -0.49% vs. -0.46%, p=0.563). A single sNfL assessment at baseline was not prognostic for on-study relapses or disability worsening. Results were similar in the subgroup of recently diagnosed, treatment-naive patients. Conclusion: This study confirms that baseline sNfL levels are prognostic of future on-study lesion formation and whole brain and regional atrophy in all RMS patients, including recently diagnosed, treatment-naive patients.

Efficacy and safety of ofatumumab in recently diagnosed, treatment-naive patients with multiple sclerosis: Results from ASCLEPIOS I and II.

BACKGROUND: In the phase III ASCLEPIOS I and II trials, participants with relapsing multiple sclerosis receiving ofatumumab had significantly better clinical and magnetic resonance imaging (MRI) outcomes than those receiving teriflunomide. OBJECTIVES: To assess the efficacy and safety of ofatumumab versus teriflunomide in recently diagnosed, treatment-naive (RDTN) participants from ASCLEPIOS. METHODS: Participants were randomized to receive ofatumumab (20 mg subcutaneously every 4 weeks) or teriflunomide (14 mg orally once daily) for up to 30 months. Endpoints analysed post hoc in the protocol-defined RDTN population included annualized relapse rate (ARR), confirmed disability worsening (CDW), progression independent of relapse activity (PIRA) and adverse events. RESULTS: Data were analysed from 615 RDTN participants (ofatumumab: n = 314; teriflunomide: n = 301). Compared with teriflunomide, ofatumumab reduced ARR by 50% (rate ratio (95% confidence interval (CI)): 0.50 (0.33, 0.74); p < 0.001), and delayed 6-month CDW by 46% (hazard ratio (HR; 95% CI): 0.54 (0.30, 0.98); p = 0.044) and 6-month PIRA by 56% (HR: 0.44 (0.20, 1.00); p = 0.049). Safety findings were manageable and consistent with those of the overall ASCLEPIOS population. CONCLUSION: The favourable benefit-risk profile of ofatumumab versus teriflunomide supports its consideration as a first-line therapy in RDTN patients.ASCLEPIOS I and II are registered at ClinicalTrials.gov (NCT02792218 and NCT02792231).

COVID-19 Outcomes and Vaccination in People with Relapsing Multiple Sclerosis Treated with Ofatumumab.

INTRODUCTION: The SARS-CoV-2 pandemic necessitated better understanding of the impact of disease-modifying therapies on COVID-19 outcomes and vaccination. We report characteristics of COVID-19 cases and vaccination status in ofatumumab-treated relapsing multiple sclerosis (RMS) patients. METHODS: COVID-19 data analyzed were from the ongoing, open-label, long-term extension phase 3b ALITHIOS study from December 2019 (pandemic start) and post-marketing cases from August 2020 (ofatumumab first approval) up to 25 September 2021. COVID-19 cases, severity, seriousness, outcomes, vaccination status, and breakthrough infection were evaluated. RESULTS: As of 25 September 2021, 245 of 1703 patients (14.4%) enrolled in ALITHIOS receiving ofatumumab (median exposure: 2.45 years) reported COVID-19 (confirmed: 210; suspected: 35). Most COVID-19 was of mild (44.1%) or moderate (46.5%) severity, but 9% had severe/life-threatening COVID-19. There were 24 serious cases (9.8%) with 23 patients hospitalized; 22 recovered and 2 died. At study cut-off, 241 patients (98.4%) had recovered or were recovering or had recovered with sequelae and 2 (0.8%) had not recovered. Ofatumumab was temporarily interrupted in 39 (15.9%) patients. Before COVID-19 onset, IgG levels were within the normal range in all COVID-19-affected patients, while IgM was < 0.4 g/l in 23 (9.4%) patients. No patient had a reinfection. Overall, 559 patients were vaccinated (full, 476; partial, 74; unspecified, 9). Breakthrough infection was reported in 1.5% (7/476) patients, and 11 reported COVID-19 after partial vaccination. As of 25 September 2021, the Novartis Safety Database (~ 4713 patient-treatment years) recorded 90 confirmed COVID-19 cases receiving ofatumumab. Most cases were non-serious (n = 80), and ten were serious (1 medically significant, 9 hospitalized, 0 deaths). Among 36 of 90 cases with outcomes reported, 30 recovered and 6 did not recover. CONCLUSION: COVID-19 in RMS patients on ofatumumab was primarily of mild/moderate severity and non-serious in these observational data. Most recovered from COVID-19 without treatment interruption. Two people died with COVID-19. Breakthrough COVID-19 despite being fully/partially vaccinated was uncommon.

Amplification of CCND1 in Urothelial Carcinoma.

OBJECTIVES: Urothelial carcinoma (UC) is the most prevalent form of bladder cancer and a significant cause of mortality in the world each year. As molecular genetic techniques improve, researchers and medical professionals are turning toward finding potential biomarkers to diagnose and characterize UC, guide treatment decisions, and use as therapeutic targets. Located on chromosome 11q13.2, the CCND1 gene encodes Cyclin D1, a CDK-regulating protein that plays a critical role in cell cycle progression. Amplification of CCND1 is seen in about 10% of all bladder cancer patients and has been a target of research due to its potential as a prognostic biomarker and a therapeutic target. However, existing literature on CCND1 amplification and Cyclin D1 expression report conflicting information about their clinical significance and association with disease staging, pointing to the need for more research to determine mechanistic pathways. Additionally, while there are currently no approved therapies or drugs that directly target CCND1 or Cyclin D1 in UC, several clinical trials with drugs targeting CDK4/CDK6 in the Cyclin D1 pathway are already underway. This paper aims to provide an update on the amplification of CCND1 in urothelial carcinoma, including an overview of recent research on elucidated pathways, clinical significance, relevant therapies under development, and directions for future research.

Safety experience with continued exposure to ofatumumab in patients with relapsing forms of multiple sclerosis for up to 3.5 years.

BACKGROUND: Ofatumumab is approved for the treatment of relapsing multiple sclerosis (RMS). Ongoing safety reporting is crucial to understand its long-term benefit-risk profile. OBJECTIVE: Report the safety and tolerability of ofatumumab in RMS after extended treatment up to 3.5 years. METHODS: Patients completing ASCLEPIOS I/II (phase 3), APLIOS, or APOLITOS (phase 2) trials could enter ALITHIOS, a phase 3b, open-label, long-term safety study. We analyzed cumulative data of continuous ofatumumab treatment and of patients newly switched from teriflunomide. RESULTS: The safety population had 1969 patients: 1292 continuously treated with ofatumumab (median time-at-risk 35.5 months, 3253 patient-years) and 677 newly switched (median time-at-risk 18.3 months, 986 patient-years). A total of 1650 patients (83.8%) had ⩾1 adverse events and 191 (9.7%) had ⩾1 serious adverse events. No opportunistic infections or progressive multifocal leukoencephalopathy events were identified; the risk of malignancies was low. Mean serum immunoglobulin (Ig) G levels remained stable. Mean IgM levels decreased but remained above the lower limit of normal in most. Serious infection incidence was low; decreased Ig levels were not associated with serious infections. CONCLUSION: In patients with up to 3.5 years' exposure, ofatumumab was well tolerated, with no new safety risks identified. These findings, with its established effectiveness, support a favorable benefit-risk profile of ofatumumab in RMS.

Rapid and sustained B-cell depletion with subcutaneous ofatumumab in relapsing multiple sclerosis: APLIOS, a randomized phase-2 study.

BACKGROUND: Ofatumumab, the first fully human anti-CD20 monoclonal antibody, is approved in several countries for relapsing multiple sclerosis (RMS). OBJECTIVE: To demonstrate the bioequivalence of ofatumumab administered by an autoinjector versus a pre-filled syringe (PFS) and to explore the effect of ofatumumab on B-cell depletion. METHODS: APLIOS (NCT03560739) is a 12-week, open-label, parallel-group, phase-2 study in patients with RMS receiving subcutaneous ofatumumab 20 mg every 4 weeks (q4w) (from Week 4, after initial doses on Days 1, 7, and 14). Patients were randomized 10:10:1:1 to autoinjector or PFS in the abdomen, or autoinjector or PFS in the thigh, respectively. Bioequivalence was determined by area under the curve (AUCτ) and maximum plasma concentration (Cmax) for Weeks 8-12. B-cell depletion and safety/tolerability were assessed. RESULTS: A total of 256 patients contributed to the bioequivalence analyses (autoinjector-abdomen, n = 128; PFS-abdomen, n = 128). Abdominal ofatumumab pharmacokinetic exposure was bioequivalent for autoinjector and PFS (geometric mean AUCτ, 487.7 vs 474.1 h × µg/mL (ratio 1.03); Cmax, 1.409 vs 1.409 µg/mL (ratio 1.00)). B-cell counts (median cells/µL) depleted rapidly in all groups from 214.0 (baseline) to 2.0 (Day 14). Ofatumumab was well tolerated. CONCLUSION: Ofatumumab 20 mg q4w self-administered subcutaneously via autoinjector is bioequivalent to PFS administration and provides rapid B-cell depletion.
