This is a Phase 2, randomized, multicenter, double masked, vehicle controlled, parallel group study to evaluate the efficacy and safety of DFL24498 topical ophthalmic solution versus vehicle in participants with dry eye disease. Approximately 417 participants aged 18 years or older who meet all eligibility criteria will be enrolled at study sites in the US. The study duration will be up to 16 weeks and will consist of three periods.
1,366 studies on the registry are indexed under Dry Eye Syndromes; 207 are open to participants now.
This study's planned enrollment of 417 is above the median of 60 across 1,129 interventional studies indexed under Dry Eye Syndromes.

Key Inclusion Criteria:
DED in at least one eye which is characterized by the following clinical features:
Key Exclusion Criteria:
Note: Additional protocol defined Inclusion/Exclusion criteria apply.
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Participants will receive DFL24498 opthalmic solution administered topically in both eyes.
Drug: DFL24498
Participants will receive vehicle opthalmic solution administered topically in both eyes.
Other: Vehicle
One drop of reconstituted DFL24498 will be instilled topically in each eyes 4 times a day (QID) for 12 weeks.
One drop of reconstituted Vehicle will be instilled topically in each eyes QID for 12 weeks.
Change from baseline in corneal fluorescein staining (CFS) assessed by National Eye Institute (NEI) scale (0 to 15) in the Study Eye
Fluorescein will be applied to the inferior fornix of the palpebral conjunctiva of each eye. To avoid the phenomenon of quenching, staining will be assessed within 1 to 4 minutes from fluorescein instillation. The CFS is performed at the slit lamp with blue (cobalt) light. The staining is graded using the NEI scale, which scores five corneal zones from 0 to 3 (total corneal score 0-15) with higher scores indicating more extensive staining.
Time frame: Baseline to Week 12
Change from baseline in ocular dryness symptom assessed by the global score of the Symptom Assessment in Dry Eye (SANDE) questionnaire
The SANDE questionnaire includes 2 VAS questions that measure the frequency and severity of DED (each scored 0-100). The global score (0-100) is calculated by multiplying the frequency score by the severity score and obtaining the square root.
Time frame: Baseline to Week 12]
Change from baseline in tear production assessed by Schirmer I test without anesthesia in the Study Eye
Before the external ocular examination and post BCVA, the Schirmer I test is performed without anesthesia to measure the wetting of the strip over 5 minutes, and the moistened length is recorded in millimeters (mm).
Time frame: Baseline to Week 12
Change from baseline; in conjunctival fluorescein staining assessed by NEI scale (0 to 18) in the Study Eye.
Fluorescein will be applied to the inferior fornix of the palpebral conjunctiva of each eye. To avoid the phenomenon of quenching, staining will be assessed within 1 to 4 minutes from fluorescein instillation. Corneal fluorescein staining is performed at the slit lamp with blue (cobalt) light. The staining is graded using the NEI scale, which scores six conjunctival zones from 0 to 3 (total conjunctival score 0-18) with higher scores indicating more extensive staining.
Time frame: Baseline to Week 12
Number of participants reporting treatment-emergent adverse events
An adverse event is any untoward medical occurrence in a clinical study participant, associated with the use of study treatment, whether or not it is considered related to the study treatment. Any adverse events occurring or worsening after the first administration of investigational product will be classified as "treatment-emergent" adverse events.
Time frame: Up to Week 14
