- Rationale: In human genetic studies a single nucleotide polymorphism within the salt-inducible kinase 1 (SIK1) gene was associated with hypertension. Lower SIK1 activity in vascular smooth muscle cells (VSMCs) leads to decreased sodium-potassium ATPase activity, which associates with increased vascular tone. Also, SIK1 participates in a negative feedback mechanism on the transforming growth factor-beta 1 signaling and downregulation of SIK1 induces the expression of extracellular matrix remodeling genes. Objective: To evaluate whether reduced expression/activity of SIK1 alone or in combination with elevated salt intake could modify the structure and function of the vasculature, leading to higher blood pressure. Methods and Results: SIK1 knockout (sik1(-/-)) and wild-type (sik1(+/+)) mice were challenged to a normal-or chronic high-salt intake (1% NaCl). Under normal-salt conditions, the sik1(-/-) mice showed increased collagen deposition in the aorta but similar blood pressure compared with the sik1(+/+) mice. During high-salt intake, the sik1+/+ mice exhibited an increase in SIK1 expression in the VSMCs layer of the aorta, whereas the sik1(-/-) mice exhibited upregulated transforming growth factor-beta 1 signaling and increased expression of endothelin-1 and genes involved in VSMC contraction, higher systolic blood pressure, and signs of cardiac hypertrophy. In vitro knockdown of SIK1 induced upregulation of collagen in aortic adventitial fibroblasts and enhanced the expression of contractile markers and of endothelin-1 in VSMCs. Conclusions: Vascular SIK1 activation might represent a novel mechanism involved in the prevention of high blood pressure development triggered by high-salt intake through the modulation of the contractile phenotype of VSMCs via transforming growth factor-beta 1-signaling inhibition.

- Background: Optimisation of dopaminergic therapy may alleviate fluctuation-related pain in Parkinson’s disease (PD). Opicapone (OPC) is a third-generation, once-daily catechol-O-methyltransferase inhibitor shown to be generally well tolerated and efficacious in reducing OFF-time in two pivotal trials in patients with PD and end-of-dose motor fluctuations. The OpiCapone Effect on motor fluctuations and pAiN (OCEAN) trial aims to investigate the efficacy of OPC 50 mg in PD patients with end-of-dose motor fluctuations and associated pain, when administered as adjunctive therapy to existing treatment with levodopa/dopa decarboxylase inhibitor (DDCi). Methods: OCEAN is a Phase IV, international, multicentre, randomised, double-blind, placebo-controlled, parallel-group, interventional trial in PD patients with end-of-dose motor fluctuations and associated pain. It consists of a 1-week screening period, 24-week double-blind treatment period and 2-week follow-up period. Eligible patients will be randomised 1:1 to OPC 50 mg or placebo once daily while continuing current treatment with levodopa/DDCi and other chronic, stable anti-PD and/or analgesic treatments. The primary efficacy endpoint is change from baseline in Domain 3 (fluctuation-related pain) of the King’s Parkinson’s disease Pain Scale (KPPS). The key secondary efficacy endpoint is change from baseline in Domain B (anxiety) of the Movement Disorder Society-sponsored Non-Motor rating Scale (MDS-NMS). Additional secondary efficacy assessments include other domains and total scores of the KPPS and MDS-NMS, the Parkinson’s Disease Questionnaire (PDQ-8), the MDS-sponsored Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) Parts III and IV, Clinical and Patient’s Global Impressions of Change, and change in functional status via Hauser’s diary. Safety assessments include the incidence of treatment-emergent adverse events. The study will be conducted in approximately 140 patients from 50 clinical sites in Germany, Italy, Portugal, Spain and the United Kingdom. Recruitment started in February 2021 and the last patient is expected to complete the study by late 2022. Discussion: The OCEAN trial will help determine whether the use of adjunctive OPC 50 mg treatment can improve fluctuation-associated pain in PD patients with end-of-dose motor fluctuations. The robust design of OCEAN will address the current lack of reliable evidence for dopaminergic-based therapy in the treatment of PD-associated pain. Trial registration: EudraCT number 2020–001175-32; registered on 2020-08-07.

- © 2017 The Authors. CNS Neuroscience & Therapeutics Published by John Wiley & Sons Ltd. Purpose: Pooled evaluation of the key efficacy and safety profile of eslicarbazepine acetate (ESL) added-on to stable antiepileptic therapy in adults with focal-onset seizures. Methods: Data from 1703 patients enrolled in four phase III double-blind, randomized, placebo-controlled studies were pooled and analyzed. Following a 2week titration period, ESL was administered at 400mg, 800mg, and 1200mg once-daily doses for 12weeks (maintenance period). Pooled efficacy variable was standardized (/4weeks) seizure frequency (SSF) analyzed over the maintenance period as reduction in absolute and relative SSF and proportion of responders (≥50% reduction in SSF). Pooled safety was analyzed by means of adverse events and clinical laboratory assessments. Results: SSF was significantly reduced with ESL 800mg (P<0.0001) and 1200mg (P<0.0001) compared to placebo. Median relative reduction in SSF was 33.4% for ESL 800mg and 37.8% for 1200mg (placebo: 17.6%), and responder rate was 33.8% and 43.1% (placebo: 22.2%). ESL was more efficacious than placebo regardless of gender, geographical region, epilepsy duration, age at time of diagnosis, seizure type, and type of concomitant antiepileptic drugs (AED). Incidence of adverse events (AEs) and AEs leading to discontinuation was dose dependent. Most common AEs (>10% patients) were dizziness, somnolence, and nausea. The incidence of treatment-emergent AEs (dizziness, somnolence, ataxia, vomiting, and nausea) was lower in patients who began taking ESL 400mg (followed by 400mg increments to 800 or 1200mg) than in those who began taking ESL 600mg or 800mg. Conclusions: Once-daily ESL 800mg and 1200mg showed consistent results across all efficacy and safety endpoints, independent of study population characteristics and type of concomitant AEDs. Treatment initiated with ESL 400mg followed by 400mg increments to 800 or 1200mg provides optimal balance of efficacy and tolerability.

- Objective: To evaluate the long-term safety, tolerability and efficacy of once-daily eslicarbazepine acetate (ESL) as adjunctive therapy in adults with partial-onset seizures. Methods: One-year open-label extension (OLE) study with ESL in patients who completed a randomised, double-blind placebo-controlled trial (study BIA-2093-302; Epilepsy Res. 89 (2010) 278-285). Starting dose was 800. mg once-daily, for 4 weeks; thereafter, dose could be individualised within the 400-1200. mg range. Doses of concomitant antiepileptic drugs were to be kept stable. Results: Overall, 325 patients were enrolled (intent-to-treat population); 223 (68.6%) patients completed 1-year of treatment. ESL median dose was 800. mg once-daily. Compared to the baseline period of the double-blind study completed prior to this OLE study, median seizure frequency decreased by 32% in weeks 1-4, and between 37% and 39% thereafter. The responder rate (seizure reduction ≥50%) was 37% during weeks 1-4 and thereafter ranged between 38% and 42% per 12-week interval. Proportion of seizure-free patients per 12-week interval ranged between 5% and 11%. Improvements from baseline in several Quality of Life in Epilepsy Inventory-31 (QOLIE-31) and Montgomery Asberg Depression Rating Scale (MADRS) scores were observed. Adverse events (AEs) were reported by 83% of patients. AEs occurring in ≥10% of patients were dizziness, headache and somnolence. AEs were usually of mild to moderate intensity. Conclusion: In this study, ESL demonstrated a sustained therapeutic effect and was well tolerated during 1-year add-on treatment of adults with partial-onset seizures. Additionally, significant improvements in quality of life domains and depressive symptoms were observed under long-term treatment with once-daily ESL. © 2012 Elsevier B.V.

- To evaluate the effects of eslicarbazepine acetate (ESL) on lipid metabolism and to determine whether reduced statin exposure during ESL therapy has clinical consequences.We conducted a post-hoc analysis of pooled data for serum lipids (laboratory values) from three phase III, multicenter, randomized, double-blind, placebo-controlled trials of adjunctive ESL therapy (400, 800, or 1200mg once daily) in patients with treatment-refractory partial-onset seizures. Changes from baseline in serum lipid levels were analyzed according to use of statins and/or enzyme-inducing antiepileptic drugs (EIAEDs) during the baseline period.In total, 426 and 1021 placebo- and ESL-treated patients, respectively, were included in the analysis. With regard to the changes from baseline in serum concentrations, there were statistically significant differences between the placebo and ESL 1200mg QD groups, for both total cholesterol (TC) and high-density lipoprotein cholesterol (HDL-C), but the effect sizes were small (+4.1mg/dL and +1.8mg/dL, respectively). A small but significant difference in low-density lipoprotein cholesterol (LDL-C; -5.0mg/dL) was observed between the ESL 400mg QD group and the placebo group. In patients not taking a concomitant EIAED, there were no changes with ESL 400mg QD, but modest and statistically significant increases in cholesterol fractions (TC, LDL-C and HDL-C) with ESL 800mg QD (<6mg/dL) and ESL 1200mg QD (<10mg/dL). ESL had no consistent effect on lipids in patients taking a concomitant EIAED. In patients taking statins during baseline, there were no clinically relevant changes in serum lipids during use of ESL, although the subgroups were small.These results suggest that ESL does not appear to have clinically significant effects on serum lipids, nor does the pharmacokinetic interaction between ESL and statins have an impact on serum lipid concentrations.

- We assessed the efficacy and safety of once-daily eslicarbazepine acetate in comparison with twice-daily (BID) controlled-release carbamazepine (carbamazepine-CR) monotherapy in newly diagnosed focal epilepsy patients.This randomized, double-blind, noninferiority trial (NCT01162460) utilized a stepwise design with 3 dose levels. Patients who remained seizure-free for the 26-week evaluation period (level A: eslicarbazepine acetate 800mg/carbamazepine-CR 200mg BID) entered a 6-month maintenance period. If a seizure occurred during the evaluation period, patients were titrated to the next target level (level B: eslicarbazepine acetate 1200mg/carbamazepine-CR 400mg BID, level C: eslicarbazepine acetate 1600mg/carbamazepine-CR 600mg BID) and the evaluation period began again. The primary endpoint was the proportion of seizure-free patients for 6months after stabilization in the per protocol set. The predefined noninferiority criteria were -12% absolute and -20% relative difference between treatment groups.Eight hundred fifteen patients were randomly assigned; 785 (388 in the eslicarbazepine acetate group and 397 in the carbamazepine-CR group) were included in the per protocol set, and 813 (401 in the eslicarbazepine acetate group and 412 in the carbamazepine-CR group) were included in the full analysis set for the primary analysis. Overall, 71.1% of eslicarbazepine acetate-treated patients and 75.6% of carbamazepine-CR-treated patients were seizure-free for ≥6months at the last evaluated dose (average risk difference = -4.28%, 95% confidence interval [CI] = -10.30 to 1.74; relative risk difference = -5.87%, 95% CI = -13.50 to 2.44) in the per protocol set. Rates of treatment-emergent adverse events were similar between groups for patients in the safety set. Noninferiority was also demonstrated in the full analysis set, as 70.8% of patients with eslicarbazepine acetate and 74.0% with carbamazepine-CR were seizure-free at the last evaluated dose (average risk difference = -3.07, 95% CI = -9.04 to 2.89).Treatment with eslicarbazepine acetate was noninferior to BID carbamazepine-CR. With its once-daily formulation, eslicarbazepine acetate provides a useful option for first-line monotherapy for adults with newly diagnosed epilepsy and focal onset seizures.
