Ocular Therapeutix™ Announces Dosing of First Patient in OTX-TKI (tyrosine kinase inhibitor implant) Phase 1 Clinical Trial for the Treatment of Wet Age-related Macular Degeneration (AMD)

Ocular Therapeutix™, Inc. (NASDAQ: OCUL), a biopharmaceutical company
focused on the formulation, development, and commercialization of
innovative therapies for diseases and conditions of the eye, today
announced the dosing of the first patient in a Phase 1 trial of OTX-TKI
(tyrosine kinase inhibitor implant) in patients with wet Age-related
Macular Degeneration (AMD). The first patient was dosed at the Sydney
Retina Clinic in Sydney, Australia.

“We are excited to announce the first patient has been successfully
dosed in our Phase 1 program with OTX-TKI, our tyrosine kinase inhibitor
implant for the treatment of serious retinal disease,” said Michael
Goldstein, M.D., Chief Medical Officer at Ocular Therapeutix. “Our trial
is primarily intended to demonstrate safety, but we will also evaluate
biological activity in patients with increased retinal thickness and
measure whether there are decreases over time. Given that TKI’s act
upstream of VEGF inhibitors, we believe this Phase 1 trial may bring us
one step closer to understanding whether TKI’s may represent a
next-generation treatment for wet AMD and diabetic macular edema.”

The Phase 1 trial is a multi-center, open-label study testing the
safety, durability, and tolerability of OTX-TKI, a bioresorbable
hydrogel fiber implant formulated with a tyrosine kinase inhibitor
delivered by intravitreal injection to patients with wet AMD. The study
will evaluate biological activity by measuring retinal thickness using
standard optical coherence tomography and following visual acuity over
time.

About OTX-TKI (tyrosine kinase inhibitor implant) Intravitreal
Injection
OTX-TKI is a bioresorbable hydrogel formulated with
TKI particles in an injectable fiber that can be delivered through a
small-gauge, sterile injection needle to the back of the eye. OTX-TKI is
designed to deliver drug to the target tissues for a period of up to
nine months, thereby potentially extending the dosing interval from the
one - to two - month frequency needed with the current standard of care.
Preclinical data have demonstrated the ability to deliver TKI to the
posterior segment of the eye with sustained
pharmacokinetic/pharmacodynamic effect for the treatment of VEGF-induced
retinal leakage for a duration of up to twelve months.

About Ocular Therapeutix, Inc.
Ocular Therapeutix, Inc.
is a biopharmaceutical company focused on the formulation, development,
and commercialization of innovative therapies for diseases and
conditions of the eye using its proprietary bioresorbable hydrogel-based
formulation technology. Ocular Therapeutix’s first commercial drug
product, DEXTENZA®, is FDA-approved for the treatment of ocular pain
following ophthalmic surgery. OTX-TP (intracanalicular travoprost
insert) is an intracanalicular insert in Phase 3 clinical development
for the reduction of intraocular pressure in patients with primary
open-angle glaucoma and ocular hypertension. The Company’s earlier stage
assets include OTX-TIC, an extended-delivery intracameral travoprost
implant for the reduction of intraocular pressure in patients with
glaucoma and ocular hypertension, as well as sustained release
intravitreal implants for the treatment of retinal diseases. These
intravitreal implants include OTX-TKI, containing a tyrosine kinase
inhibitor (TKI), and, in collaboration with Regeneron, OTX-IVT, an
extended-delivery protein-based anti-vascular endothelial growth factor
(VEGF) trap. Ocular Therapeutix's first product, ReSure® Sealant, is
FDA-approved to seal corneal incisions following cataract surgery.
