Real-world effectiveness of a single conventional disease-modifying anti-rheumatic drug (cDMARD) plus an anti-TNF agent versus multiple cDMARDs in rheumatoid arthritis: a prospective observational study

Article

Author: Choe, Jung-Yoon ; PharmD ; Sung, Yoon-Kyoung ; Kim, Jin Ran ; Lee, Sang-Heon ; Kim, Dong Wook ; Lee, Sang-Il ; Kim, Sang-Hyon ; Lee, Hye-Soon ; So, Min Wook ; Hur, Jin-Wuk

ObjectiveThe objective of this prospective, observational multicenter study (NCT03264703) was to compare the effectiveness of single conventional disease-modifying anti-rheumatic drug (cDMARD) plus anti-tumor necrosis factor (TNF) therapy versus multiple cDMARD treatments in patients with moderate-to-severe rheumatoid arthritis (RA) following cDMARD failure in the real-world setting in South Korea.MethodsAt the treating physicians' discretion, patients received single cDMARD plus anti-TNF therapy or multiple cDMARDs. Changes from baseline in disease activity score 28-joint count with erythrocyte sedimentation rate (DAS28-ESR), corticosteroid use, and Korean Health Assessment Questionnaire (KHAQ-20) scores were evaluated at 3, 6, and 12 months.ResultsOf 207 enrollees, the final analysis included 45 of 73 cDMARD plus anti-TNF and 91 of 134 multiple-cDMARD recipients. There were no significant between-group differences (BGDs) in ANCOVA-adjusted changes from baseline in DAS28-ESR at 3, 6 (primary endpoint), and 12 months (BGDs -0.18, -0.38, and -0.03, respectively). More cDMARD plus anti-TNF than multiple-cDMARD recipients achieved a >50% reduction from baseline in corticosteroid dosage at 12 months (35.7% vs 14.6%; p=0.007). Changes from baseline in KHAQ-20 scores at 3, 6, and 12 months were significantly better with cDMARD plus anti-TNF therapy than with multiple cDMARDs (BGD -0.18, -0.19, and -0.19 points, respectively; all p≤0.024).ConclusionIn the real-world setting, relative to multiple cDMARDs, single cDMARD plus anti-TNF therapy significantly improved quality-of-life scores and reduced corticosteroid use, with no significant BGD in disease activity, in RA patients in whom previous cDMARD therapy had failed.

Treatment compliance, treatment patterns, and healthcare utilization in epilepsy patients with first add-on antiepileptic drugs: A nationwide cohort study

Article

Author: Kim, Jung-Ae ; Kim, Min Young ; Lee, Youngeun ; Lee, Sang Kun

ObjectiveThis study aimed to assess the treatment compliance, patterns, healthcare resource utilization (HCRU), and costs of anti-epilepsy drugs (AEDs) as the first add-on therapy in patients with epilepsy.MethodsWe conducted a retrospective population-based cohort study using Korean National Health Insurance claims data from 2016 to 2020. Patients with epilepsy who newly received AED add-on therapy were identified and followed for up to 12 months to evaluate persistence, adherence, treatment patterns, HCRU, and costs.ResultsAmong 6,746 patients who initiated AED add-on therapy, 65.5% were persistent on their index AED add-on from the index date until the end of the follow-up period, and the mean persistent time on the index add-on was 307.3 ± 92.3 days. A total of 76.8% patients were adherent, with a medication possession ratio (MPR) ≥80%, and the mean MPR was 88.9 ± 25.4%. Persistence and adherence to the index AED add-on were relatively higher among patients prescribed lamotrigine, levetiracetam, oxcarbazepine, and perampanel than those prescribed carbamazepine, topiramate, or valproate. A total of 41.0% of the patients changed their index AED add-on during the follow-up period. The carbamazepine, topiramate, and valproate groups had higher rates of change than the other AED groups. HCRU and costs tended to be lower in the lamotrigine, levetiracetam, oxcarbazepine, and perampanel groups. Furthermore, perampanel showed the lowest HCRU and costs for all-cause cases as well as the lowest length of stay and outpatient visits for epilepsy-related cases.ConclusionIn this population-based study, the use of lamotrigine, levetiracetam, oxcarbazepine, or perampanel as the first add-on therapy in patients with epilepsy contributed to better treatment compliance and lower HCRU and costs than that of carbamazepine, topiramate, or valproate.

Safety and effectiveness of perampanel monotherapy after adjunctive therapy through retention rate in subjects with focal-onset seizures with or without focal to bilateral tonic-clonic seizures: A multicenter retrospective study in Korea.

Article

Author: Lee, Won Gu ; Kim, Kwang Ki ; Seo, Dae-Won ; Kim, Dong Wook ; Lim, Sung Chul ; Lee, Yoona ; Park, Jihyun ; Shon, Young-Min

OBJECTIVETo assess the effectiveness and tolerability of perampanel monotherapy following conversion from adjunctive therapy.METHODSThis was a multicenter, retrospective, non-interventional study of Korean patients aged ≥12 years with focal-onset seizures (FOS) with or without focal to bilateral tonic-clonic seizures. Data were extracted from electronic medical records of perampanel-treated patients from 1 February 2016 to 31 October 2020. Kaplan-Meier estimated retention rates, effectiveness, and safety were recorded.RESULTSSubjects (n = 66, mean age 46.2 years) were mostly male (68.2%) with focal to bilateral tonic-clonic seizure (71.2%). Mean duration of illness was 86.3 months. Retention rates after conversion to perampanel monotherapy at 3, 6, and 12 months (primary outcome) were 96.0%, 96.0%, and 75.6%, respectively. Overall retention rates in patients receiving perampanel as adjunctive or monotherapy at 3, 6, 12, 18, and 24 months after perampanel add-on were 100%, 98.3%, 95.9%, 92.6%, and 92.6%, respectively. Mean retention duration was 41.2 months (overall perampanel administration) and 21.4 months (monotherapy). Mean seizure frequency/28 days in the Full Analysis Set (n = 61) was comparable for adjunctive and monotherapy (0.2 ± 0.79 vs 0.2 ± 0.64; change between adjunctive and monotherapy periods: 0.0 ± 0.59; p = 0.498). Perampanel was well tolerated and no new safety signals were identified. Dizziness (4.6%), only reported during adjunctive therapy, was the most common treatment-emergent adverse event.CONCLUSIONSConversion to perampanel monotherapy from adjunctive therapy showed promising results in subjects with FOS with/without focal to bilateral tonic-clonic seizures; further studies in a larger population are needed to confirm these encouraging data.

South Korea’s MFDS approves Eisai-Biogen’s LEQEMBI for Alzheimer’s

LEQEMBI is indicated for use in adults with mild cognitive impairment or mild Alzheimer’s disease (AD). Credit: fizkes / Shutterstock.com. The South Korean Ministry of Food and Drug Safety (MFDS) has granted approval for Eisai and Biogen ’s LEQEMBI (lecanemab) for use in adults with mild cognitive impairment due to mild Alzheimer’s disease (AD). This marks South Korea as the fourth nation to approve the treatment after the US, China and Japan. LEQEMBI is a humanised anti-soluble aggregated amyloid-beta (Aβ) monoclonal antibody that targets both soluble Aβ aggregates (protofibrils) and insoluble Aβ aggregates (fibrils) found in AD. Lecanemab is developed through a research alliance between Eisai and BioArctic. It is claimed to be the first and only treatment demonstrated to lower disease progression and slow down cognitive and functional decline. See Also: South Korea’s MFDS approves Eisai-Biogen’s LEQEMBI for Alzheimer’s EC approves Celltrion’s Omlyclo for allergic conditions Eisai is overseeing the development and regulatory submissions for LEQEMBI globally, with joint commercialisation and promotion of the product alongside Biogen. Eisai retains the final decision-making authority. In South Korea, Eisai Korea will manage the distribution and information provision activities related to LEQEMBI. Lecanemab is approved in the US to treat AD in patients with mild cognitive impairment (MCI) or mild dementia stage of the disease. The FDA’s approval of LEQEMBI was based on the data from Phase III Clarity AD clinical trial. The trial met its primary endpoint and all key secondary endpoints with statistically significant results. Eisai also filed applications for lecanemab’s approval in 13 countries and regions, including the European Union. In the US, a supplemental biologics license application (sBLA) for intravenous maintenance dosing was submitted in March this year. Additionally, the rolling submission of a biologics license application (BLA) for a subcutaneous injection formulation began recently under fast track status, aiming to enhance patient convenience.
