Abstract

Introduction:

We report efficacy and safety of lebrikizumab up to 152 weeks (W) of continuous treatment with/without topical corticosteroids in the ADjoin long-term extension study.

Methods:

ADvocate1&2 W16 lebrikizumab responders (Eczema Area and Severity Index (EASI) 75 or Investigator's Global Assessment (IGA) 0/1 without rescue) were re-randomized 2:2:1 lebrikizumab (LEB) 250 mg Q2W, Q4W, or placebo (lebrikizumab withdrawal, not presented herein) to the 36W maintenance period before entering ADjoin. ADhere W16 lebrikizumab responders were re-randomized 2:1 LEBQ2W/Q4W upon entering ADjoin. Data are reported as observed for W16 lebrikizumab responders from ADvocate1&2 (N = 181) and ADhere (N = 86) who received treatment up to ADjoin W100 (152W/116W for ADvocate1&2/ADhere). The Supplement reports additional populations.

Results:

In participants who achieved IGA 0/1 at W16, 84.0% (Q4W) and 82.9% (Q2W) from ADvocate1&2 maintained IGA 0/1 at W152; 91.7% and 86.7% from ADhere maintained response at W116. Among participants achieving EASI 75 at W16, 94.1% (Q4W) and 90.5% (Q2W) from ADvocate1&2 maintained EASI 75 at W152; 90.9% and 94.9% from ADhere maintained EASI 75 at W116. Most adverse events (AEs) were mild (29.2%) or moderate (33.3%) in severity; 3.7% reported serious AEs; 2.6% reported AEs leading to treatment discontinuation.

Conclusion:

Lebrikizumab maintained efficacy up to 3 years of continuous treatment in LEB 250 mg Q2W and Q4W W16 lebrikizumab per-protocol responders. The safety profile was consistent with previous studies.

Antiasthma Drugs: Leukotriene Modifiers

Antiasthma Drugs: Leukotriene Modifiers

Leukotriene modifiers, or cysteinyl leukotriene receptor antagonists, are medications used to manage chronic asthma. These agents target specific inflammatory mediators produced during arachidonic acid metabolism, an essential process in generating inflammation in the body.
Leukotriene modifiers work through two distinct mechanisms:

Antiepileptic Drugs: Potassium Channel Activators

Antiepileptic Drugs: Potassium Channel Activators

Ezocgabine or retigabine, an antiepileptic drug of remarkable efficacy, has revolutionized the management of seizures. It is a potassium channel activator, explicitly targeting the family of Q subtype potassium channels. It enhances the transmembrane potassium currents, regulating neuronal excitability. This action stabilizes the resting membrane potential, a pivotal factor in mitigating the hyperexcitability that characterizes epilepsy.
Ezogabine has gained approval as an adjunctive treatment...

Asthma III: Clinical Manifestations

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein

Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...
