Efficacy and safety of mirikizumab in patients with moderately-to-severely active Crohn's disease: a phase 3, multicentre, randomised, double-blind, placebo-controlled and active-controlled, treat-through study.

Background: Mirikizumab, a humanised monoclonal antibody that inhibits IL-23p19, is effective in moderate-to-severe ulcerative colitis. We aimed to evaluate the efficacy and safety of mirikizumab in patients with moderately-to-severely active Crohn's disease.

Methods: VIVID-1 was a global phase 3, randomised, double-blind, double-dummy, placebo-controlled and active-controlled, treat-through study.

Migraine history and response to lasmiditan across racial and ethnic groups.

Objective: The robust enrollment in SPARTAN and SAMURAI provided the opportunity to present post-hoc descriptive details on migraine disease characteristics and treatment outcomes after treatment with lasmiditan, a selective serotonin (5-HT) receptor agonist, in racial and ethnic subgroups.

Methods: Descriptive data from racial (White [W]( = 3471) and Black or African American [AA]( = 792)) and ethnic (Hispanic or Latinx [HL]( = 775) and Non-Hispanic or Latinx [Non-HL]( = 3637)) populations are presented on pooled data from two double-blind, placebo-controlled, randomized Phase 3 studies (SAMURAI [NCT02439320] and SPARTAN [NCT2605174]). Patients were treated with lasmiditan (50 (SPARTAN only), 100, or 200 mg) or placebo for a single migraine attack of moderate-to-severe intensity.

Lanabecestat: Neuroimaging results in early symptomatic Alzheimer's disease.

Introduction: Lanabecestat, a beta-site amyloid precursor protein-cleaving enzyme 1 (BACE1) inhibitor, was investigated as a potential Alzheimer's disease (AD)-modifying treatment. As previously reported, amyloid beta (Aβ) neuritic plaque burden reduction did not result in clinical benefit. Lanabecestat's effects on neuroimaging biomarkers and correlations between neuroimaging biomarkers and efficacy measures are reported.

Randomized, controlled trial of lasmiditan over four migraine attacks: Findings from the CENTURION study.

Background: We present findings from the multicenter, double-blind Phase 3 study, CENTURION. This study was designed to assess the efficacy of and consistency of response to lasmiditan in the acute treatment of migraine across four attacks.

Methods: Patients were randomized 1:1:1 to one of three treatment groups - lasmiditan 200 mg; lasmiditan 100 mg; or a control group that received placebo for three attacks and lasmiditan 50 mg for either the third or fourth attack.

Efficacy and Safety of Lanabecestat for Treatment of Early and Mild Alzheimer Disease: The AMARANTH and DAYBREAK-ALZ Randomized Clinical Trials.

Importance: Alzheimer disease (AD) is a neurodegenerative disorder characterized by cognitive deterioration and impaired activities of daily living. Current treatments provide only minor symptomatic improvements with limited benefit duration. Lanabecestat, a brain-permeable inhibitor of human beta-site amyloid precursor protein-cleaving enzyme 1 (BACE1/β-secretase), was developed to modify the clinical course of AD by slowing disease progression.
