Oxurion NV - Data from a Phase 1/2 Clinical Study evaluating THR-317 (anti-PlGF) for DME presented at 2019 FLORetina Meeting
06 Juin 2019 - 7:00PM
Leuven, Belgium,
6th June 2019
- 7 PM CET - Oxurion NV (Euronext
Brussels: OXUR), a biopharmaceutical company developing innovative
treatments to preserve vision in patients with diabetic eye
disease, announced that today clinical-stage data from a Phase 1/2
study evaluating its anti-placental growth factor candidate THR-317
for the treatment of diabetic macular edema (DME) were presented at
the biannual Retina Meeting (FLORetina 2019) in Florence, Italy.
THR-317 (anti-PlGF) is a recombinant humanized monoclonal antibody
directed against the receptor-binding site of human placental
growth factor (PlGF).
Professor Anat
Loewenstein, MD MHA, Professor of Ophthalmology, Chair of the
Ophthalmology Division at the Tel Aviv Medical Center,
delivered a presentation entitled "A Phase 1/2 safety and efficacy
study of Anti-PlGF (THR-317) in diabetic macular edema". The
Phase 1/2 study enrolled 49 patients and comprised anti-VEGF naïve
patients as well as sub-optimal anti-VEGF responders.
The presentation highlighted
results from a Phase 1/2 trial evaluating the safety and efficacy
of intra-ocular THR-317 at 2 dose levels (4 mg and 8 mg) for the
treatment of DME. The study met its primary endpoint of safety for
both the 4mg and 8mg doses. Efficacy was also observed in the
study. Overall, patients receiving the 8mg dose of THR-317
achieved better visual acuity outcomes than in the 4mg dose
group.
In April 2018, Day 90 (30 days
after last injection) topline data announced from this Phase 1/2
study demonstrated that intra-ocular THR-317 was safe and well
tolerated. The data also showed that 30% of anti-VEGF
treatment naïve patients achieved a >15
letter vision gain in BCVA (Best Corrected Visual Acuity).
In July 2018, Day 150 (90
days after last injection) topline data from this study showed that
in the 8mg anti-VEGF treatment naïve group, 30% of these
patients achieved a > 10 letter vision gain and 10% showed
a >15 letter vision gain. The Day 150 data demonstrate the
durability of THR-317's positive effect on vision in this patient
population.
Professor Anat
Loewenstein, commented: "I feel encouraged by
these Phase 1/2 data that show safety and efficacy of the 8mg dose
of THR-317 in patients with DME. I look forward to seeing the
outcome of the proof of concept Phase 2 trial that is due in the
coming months. These data will provide important insights into the
additional effect anti-PlGF could provide on top of anti-VEGF
therapy, the current standard of care for treating DME
patients."
A Phase 2 study of 8mg THR-317 in
combination with anti-VEGF (ranibizumab, Lucentis®) is on-going.
The study is evaluating THR-317, in combination with conventional
anti-VEGF therapy (Lucentis®), versus anti-VEGF therapy (and sham)
for the treatment of DME. In April 2019, Oxurion announced full
enrollment of this Phase 2 study (n=70) ahead of schedule.
Topline data from this Phase 2
study are expected in Q3 2019.

is a biopharmaceutical company currently developing a competitive
pipeline of disease-modifying drug candidates for diabetic eye
disease, a leading cause of blindness in people of working age
worldwide.
Oxurion's most advanced drug candidate is THR-317, a PlGF inhibitor
for the treatment of diabetic macular edema (DME), which is
currently in a Phase 2 study in combination with
Lucentis®. THR-317 is
also being evaluated in a Phase 2 study for the treatment of
Idiopathic Macular Telangiectasia Type 1 (MacTel 1), a rare retinal
disease that affects the macula and can lead to vision
loss.
Oxurion has two further pipeline candidates, THR-149, a plasma
kallikrein inhibitor being developed for the treatment of DME; and
THR-687, a pan-RGD integrin antagonist in development for the
treatment of diabetic retinopathy and DME. Both THR-149 and THR-687
are in Phase 1 clinical studies.
