- Registration Number
- NCT03517748
- Lead Sponsor
- Horus Pharma
- Brief Summary
This study is a multicentric, comparative, randomized, investigator-blinded, in parallel groups study to demonstrate the non-inferiority of DM05 in comparison with Optive™, in terms of cornea and conjunctiva staining (Oxford score) on patients with moderate to severe ocular dryness, after 35 days of treatment.
- Detailed Description
Evaluation of the non-inferiority of DM05 in comparison with OptiveTM, in terms of cornea and conjunctiva staining (Oxford score), on worse eye, between D0 and D35.
* Comparison of D35 versus D0 and D84 versus D0 for each product and comparison between products for the following parameters:
* Evolution of cornea and conjunctiva staining (Oxford score) on worse eye.
* Evolution of OSDI score (Ocular Surface Disease Index).
* Evolution of Van Bijsterveld score (Lissamine green staining) in worse eye.
* Evolution of Schirmer test result in worse eye.
* Evolution of Tear film Break-Up Time (TBUT) in worse eye.
* Evolution of ocular dryness severity by evaluation of each main symptom by the patient and total score of all symptoms
* Evaluation of treatment performance by the investigator and the patient.
* Evaluation of the average frequency of use during 84 days for DM05 and OptiveTM.
