Lifitegrast is a FDA approved drug for the treatment of keratoconjunctivitis sicca (dry eye syndrome). It is a tetrahydroisoquinoline derivative and lymphocyte function-associated antigen-1 ( LFA-1) antagonist that was discovered through the rational design process. The ophthalmic solution was approved in July, 2016 under the trade name Xiidra. It has shown to protect the corneal surface and alleviate the symptoms of dry eye syndrome with fast onset of action and well tolerated profile in both local and systemic setting.
Lifitegrast is a Lymphocyte Function-Associated Antigen-1 Antagonist. The mechanism of action of lifitegrast is as a Lymphocyte Function-Associated Antigen-1 Antagonist.

4 Drug and Medication Information
4.1 Drug Indication

For the treatment of signs and symptoms of keratoconjunctivitis sicca (dry eye syndrome).


FDA Label


Treatment of dry eye disease


5 Pharmacology and Biochemistry
5.1 Pharmacology

Lifitegrast addresses both the symptoms and the resulting ocular surface damage by interfering with ocular inflammatory cycle. Lifitegrast is a lymphocyte functionassociated antigen-1 antagonist through direct competitive antagonism and sequentially inhibits the T-cell recruitment, activation, and proinflammatory cytokine release associated with dry eye syndrome.


5.2 MeSH Pharmacological Classification

Ophthalmic Solutions

Sterile solutions that are intended for instillation into the eye. It does not include solutions for cleaning eyeglasses or CONTACT LENS SOLUTIONS. (See all compounds classified as Ophthalmic Solutions.)

5.5 Absorption, Distribution and Excretion

Absorption

The mean peak plasma concentration (Cmax) of 1.70ng/mL was reached within 15 minutes of application. Quantifiable trough plasma concentrations ranged from 0.55 ng/mL to 3.74 ng/mL. Observations show limited systemic exposure that produces significant clinical outcomes.


Route of Elimination

Not possible to perform mass balance study to determine the main route of elimination.


Clearance

Not possible to calculate clearance rate based on plasma concentrations of lifitegrast, but reported to be relatively fast in rat I.V. pharmacokinetics study. It is predicted that lifitegrast is cleared via nasal and subsequently gastrointestinal tract.


5.6 Metabolism/Metabolites

Based on the findings of an in vitro metabolism study using fresh human hepatocytes, lifitegrast does not appear to undergo significant metabolism.


5.7 Biological Half-Life

Not possible to calculate plasma elimination half-life based on plasma concentrations of lifitegrast, but reported to be relatively short in rat I.V. pharmacokinetics study.


5.8 Mechanism of Action

Lifitegrast binds to the integrin lymphocyte function-associated antigen-1 (LFA-1), a cell surface protein found on leukocytes and blocks the interaction of LFA-1 with its cognate ligand intercellular adhesion molecule-1 (ICAM-1). ICAM-1 may be overexpressed in corneal and conjunctival tissues in dry eye disease. LFA-1/ICAM-1 interaction can contribute to the formation of an immunological synapse resulting in T-cell proliferation/activation and migration to target tissues. In vitro studies demonstrated that lifitegrast may inhibit T-cell adhesion to ICAM-1 in a human T-cell line and may inhibit secretion of inflammatory cytokines, inflammatory mediators, chemokines, TNF-, and IL-1 in human peripheral blood mononuclear cells.
