Conditions ocular hypertension, open-angle glaucoma
Treatment latanoprost punctal plug delivery system (l-ppds)
Phase phase 2
Sponsor Mati Therapeutics Inc.
Start date December 2013
End date December 2016
Trial size 86 participants
Trial identifier NCT02014142, PPL GLAU M1


Compare efficacy of the latanoprost punctal plug to timolol maleate ophthalmic gel forming solution (GFS) 0.5% (administered once every morning). Effect of configuration of L-PPDS placement on efficacy will also be examined.

Study Design

Allocation randomized
Intervention model parallel assignment
Masking single blind (outcomes assessor)
Primary purpose treatment
Latanoprost Punctal Plug Delivery System (L-PPDS) continuous single occlusion; L-PPDS will be inserted in the lower punctum and no plug will be inserted in the upper punctum of each eye; L-PPDS will remain for a period of 14 weeks.
latanoprost punctal plug delivery system (l-ppds)
Latanoprost Punctal Plug Delivery System (L-PPDS)
Latanoprost Punctal Plug Delivery System (L-PPDS) continuous double occlusion; L-PPDS will be inserted in the lower punctum and non-therapeutic (NT) plug will be inserted in the upper punctum of each eye and both will remain for a period of 14 weeks.

Subject with a history of non-response to topical prostaglandin eye drops for OAG/OH 2. Subject with angle-closure glaucoma, neovascular glaucoma, traumatic glaucoma or iridocorneal endothelium syndrome in either eye 3. Subject with a known sensitivity to latanoprost, timolol, fluorescein, topical anesthetic, silicone, any inactive ingredient of the L-PPDS or any other products required for the study procedures 4. Subject with a history of intolerance to topical beta-blocker therapy 5. Subject with > 0.8 vertical cup or completely notched optic nerve head rim in either eye 6. Subject with any functionally significant visual field loss or progressive field loss within the last year in either eye 7. Subject with a history of complications, AEs, trauma or disease in the nasolacrimal area, whether or not it was due to punctal plug wear, including but not limited to dacryocystitis, inflammation or canaliculitis in study eye 8. Subject with structural lid abnormalities (i.e., ectropion, entropion) in study eye 9. Subject with an active lid disease in either eye (i.e., moderate or severe blepharitis, meibomianitis) that requires medical treatment 10. Subject with a history of chronic/recurrent inflammatory eye disease (i.e., scleritis, uveitis, herpes keratitis) in either eye 11. Subject who would require the use of any ocular topical medication(s), an over-the counter drop(s), ointment(s) or gel(s), other than the study ocular hypotensive medication(s) in either eye during the study period 12. Subject who has had any ophthalmic surgical procedures (i.e., glaucoma laser, minimally invasive glaucoma surgery, cataract, refractive, etc.) in study eye within the last six months or will require ophthalmic surgery before completing the study 13. Subject with a history of penetrating keratoplasty in study eye 14. Subject who is incapable of instilling ocular drops into his or her eyes 15. Subject requiring the use of a contact lens in either eye at any time during the study period 16. Subject with advanced diabetic retinopathy, branch retinal vein occlusion or central retinal vein occlusion in either eye 17. Subject with a history of macular edema in either eye 18. Subject currently on any systemic medication [i.e., beta-blocker, carbonic anhydrase inhibitors, corticosteroids (including dermal), etc.], that may have an effect on the subject's IOP, or who will require its use during the study period (Note: an inhaled steroid, systemic beta-blocker or β-adrenoceptor antagonist may be permitted, providing the subject has maintained a stable dosage regimen for at least the last three months) 19. Subject contraindicated to therapy with a beta-blocker (i.e., history or presence of bradycardia, untreated congestive heart failure, untreated second- or third-degree heart block, sino-atrial block, myasthenia gravis, cardiogenic shock, history or presence of bronchial asthma, bronchial hyperreactivity, severe chronic obstructive pulmonary disease, or history of bronchospasm) 20.
