Clinical Trial Summary

To evaluate the benefit of treatment with a physician administered intracanalicular dexamethasone insert in evaporative dry eye disease (DED) patients with meibomian gland disfunction (MGD) and underlying inflammation undergoing LipiFlow Thermal Pulsation.


Description:

This prospective, open-label, single-center, non-randomized, investigator-sponsored clinical study seeks to investigate the benefit of managing patients with DED secondary to MGD with a sustained release intracanalicular dexamethasone (0.4 mg) insert in addition to LipiFlow Thermal Pulsation compared to LipiFlow Thermal Pulsation alone. In addition, this study will evaluate the ease of Dextenza insertion and the patient preference for therapy. After screening a given patient for inclusion and exclusion criteria, and gaining informed consent, each eye will undergo LipiFlow Thermal Pulsation on the same day. The most symptomatic eye will be selected to receive DEXTENZA® insertion on the day of the procedure (study eye), while the other eye will be assigned to a receive a sham punctum dilation (control eye). If there is no obvious symptomatic difference, the right eye will receive the intracanalicular insert. Per patient, the study period will last for approximately 12 weeks after the LipiFlow procedure, consisting of one screening visit, one treatment v4isit and 3 post-procedure follow-up visits (week 1, week 4 and week 12). At week 1, week 4 and week 12, primary and secondary endpoints will be assessed alongside standard-of-care procedures. Adjusting for enrollment period, the study will last a total of approximately 4 months.

Outcome

Type Measure Description Time frame Safety issue
Primary Change from baseline in meibomian gland scores (expressibility and quality) As measured on a grading scale 1 to 4 and graded by the physician Assessed at Baseline, Week 1, Week 4 and Week 12
Primary Patient preference for As measured by COMTOL Survey Assessed at Week 12
Secondary Mean change in MMP-9 As measured by InflammaDry Assessed at Baseline, Week 1, Week 4 and Week 12 Visit
Secondary Mean change in ocular surface staining As measured by sodium fluorescein and lissamine green Assessed at Baseline, Week 1, Week 4 and Week 12 Visit
Secondary Mean change in tear break-up time (TBUT) As measured by TBUT testing Assessed at Baseline, Week 1, Week 4 and Week 12 Visit
Secondary Mean change in tear osmolarity As measured by TearLab Assessed at Baseline, Week 1, Week 4 and Week 12 Visit
Secondary Mean change in DEQ-5 As measured by DEQ-5 Questionnaire (Dry Eye Questionnaire. The DEQ-5 is comprised of 5 items: frequency of watery eyes, discomfort, and dryness (0-4 scale) and late day discomfort and dryness intensity (0-5 scale). Higher numbers indicate more severe symptoms. Assessed at Baseline, Week 1, Week 4 and Week 12 Visit
Secondary Mean change in Best-corrected Visual Acuity (BCVA) As measured by ETDRS chart Assessed at Baseline, Week 1, Week 4 and Week 12 Visit
