Cognitive performance of patients with opioid use disorder transitioned to extended-release injectable naltrexone from buprenorphine: Post hoc analysis of exploratory results of a phase 3 randomized controlled trial.

Background: Opioid use disorder (OUD) is associated with cognitive dysfunction. Understanding how pharmacotherapy may affect cognition is an important treatment consideration.

Methods: This was a hybrid residential-outpatient, randomized trial assessing transition regimens (naltrexone/buprenorphine [NTX/BUP] vs placebo-NTX/buprenorphine [PBO-N]/BUP) to extended-release naltrexone (XR-NTX) in patients with OUD seeking BUP discontinuation.

Diroximel Fumarate Demonstrates an Improved Gastrointestinal Tolerability Profile Compared with Dimethyl Fumarate in Patients with Relapsing-Remitting Multiple Sclerosis: Results from the Randomized, Double-Blind, Phase III EVOLVE-MS-2 Study.

Background: Diroximel fumarate (DRF) is a novel oral fumarate approved in the USA for relapsing forms of multiple sclerosis. DRF is converted to monomethyl fumarate, the pharmacologically active metabolite of dimethyl fumarate (DMF). DRF 462 mg and DMF 240 mg produce bioequivalent exposure of monomethyl fumarate and are therefore expected to have similar efficacy/safety profiles; the distinct chemical structure of DRF may contribute to its tolerability profile.

Diroximel fumarate (DRF) in patients with relapsing-remitting multiple sclerosis: Interim safety and efficacy results from the phase 3 EVOLVE-MS-1 study.

Background: Diroximel fumarate (DRF) is a novel oral fumarate for patients with relapsing-remitting multiple sclerosis (RRMS). DRF and the approved drug dimethyl fumarate yield bioequivalent exposure to the active metabolite monomethyl fumarate; thus, efficacy/safety profiles are expected to be similar. However, DRF's distinct chemical structure may result in a differentiated gastrointestinal (GI) tolerability profile.

Adherence and persistence among multiple sclerosis patients after one immunomodulatory therapy failure: retrospective claims analysis.

Introduction: There are no published data on patient adherence to, and persistence with, disease-modifying therapies (DMT) for multiple sclerosis (MS) after one immunomodulatory failure. The present study compares secondline DMT adherence and persistence among patients with MS.

Methods: Patients with MS initiating a second-line treatment with natalizumab, intramuscular interferon beta-1a (i.

Comparison of adherence and persistence among multiple sclerosis patients treated with disease-modifying therapies: a retrospective administrative claims analysis.

Purpose: To compare adherence and persistence among patients with multiple sclerosis (MS) initiated on disease-modifying therapy (DMTs), including intramuscular (IM) interferon beta-1a (IFNβ-1a), subcutaneous (SC) IFNβ-1a, IFNβ-1b, or glatiramer acetate (GA).

Methods: MS patients initiated on IM-IFNβ-1a, SC-IFNβ-1a, IFNβ-1b, or GA between January 1, 2000 and January 2, 2008 were identified from a retrospective claims database study associated with a large US health plan. The date of DMT initiation was the index date; patients were observed for 6 months before and 12-36 months after the index date.

Medical chart validation of an algorithm for identifying multiple sclerosis relapse in healthcare claims.

Objective: Relapse is a common measure of disease activity in relapsing-remitting multiple sclerosis (MS). The objective of this study was to test the content validity of an operational algorithm for detecting relapse in claims data.

Methods: A claims-based relapse detection algorithm was tested by comparing its detection rate over a 1-year period with relapses identified based on medical chart review.

Immune response to influenza vaccine is maintained in patients with multiple sclerosis receiving interferon beta-1a.

Immunologic response was assessed prospectively using influenza vaccine in 86 patients with multiple sclerosis (MS) who were taking interferon beta-1a and 77 patients who were not taking interferon. Blood samples were assayed for hemagglutination inhibition (HI) titers 0, 21, and 28 days after immunization. The two groups were similar in the proportion of patients achieving an HI titer of 40 or greater, the prespecified primary end point and on all secondary indicators of immune response.
