Study Endpoints

Primary Endpoints

Mean Change From Baseline in Ocular Redness, Area Under the Curve From Time Zero to Hour 10 [AUC (0-10)] at Day 7
0.0, 0.25, 0.50, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, and 10.0 hours on Days 1 (baseline) and 7

Ocular redness ratings were collected for nasal and temporal areas of each eye and assessed by investigational center staff using a visual scale (ie, scored by comparing the subject's eye with a series of photographs) and graded on a scale from 0 (none) to 4 (extremely severe), 0.5 unit steps permitted. AUC was calculated using the trapezoidal rule with unequal intervals as determined by the assessment time points. Change was calculated as AUC(0-10)\[Day 7\] - AUC(0-10) \[Baseline\]. Both eyes contributed to the analysis.

Frequently asked questions about AL-53817, 0.1%

What is AL-53817 used for?

AL-53817 is an investigational small molecule being developed by Alcon Inc. for the treatment of allergic conjunctivitis and nasal allergies. It has been studied as a nasal spray solution for nasal allergies and as an ophthalmic solution for allergic conjunctivitis. The drug is still in clinical development and is not approved.

Who makes AL-53817?

AL-53817 is being developed by Alcon Inc., a company traded on the New York Stock Exchange under the ticker ALC. Alcon has conducted clinical trials of AL-53817 for allergic conjunctivitis and nasal allergies.

What phase is AL-53817 in?

AL-53817 has completed Phase 1 and Phase 2 clinical trials. A Phase 1 trial of the nasal spray solution for nasal allergies was completed, and a Phase 2 trial of the ophthalmic solution for allergic conjunctivitis was also completed. The drug remains investigational.

What clinical trials is AL-53817 in?

AL-53817 has been studied in two completed trials. NCT01454505 was a Phase 1 safety and efficacy study of AL-53817 nasal spray solution for nasal allergies with 110 participants. NCT02079649 was a Phase 2 study of AL-53817 and AL-78843 ophthalmic solutions for allergic conjunctivitis with 224 participants.

Is AL-53817 the same as AL-78843?

No, AL-53817 and AL-78843 are different investigational drugs. They were studied together in a Phase 2 clinical trial (NCT02079649) that evaluated both ophthalmic solutions for the treatment of allergic conjunctivitis, but they are separate compounds.
