Positive topline data reported from Phase 1 safety study evaluating THR-149 (Plasma Kallikrein Inhibitor) for treatment of DME

Leuven, Belgium – Oxurion NV (Euronext Brussels: OXUR), a biopharmaceutical company developing innovative treatments to preserve vision in patients with diabetic eye disease, today issues its business and financial update for the six-month period ending June 30, 2019.

Oxurion is continuing to progress the development of its innovative pipeline of disease modifying drug candidates for diabetic eye disease, particularly DME.
The Oxurion clinical development pipeline consists of novel products with different modes of action, which, together potentially give the Company access to a significant share of the large and fast-growing diabetic eye disease market.

Oxurion’s clinical pipeline comprises of:

  • a potent plasma kallikrein inhibitor (THR-149) is in a Phase 1 multicenter, dose escalation study for the treatment of DME. Recent positive topline data showed that THR-149 is well-tolerated and safe with no dose-limiting toxicities or drug-related serious adverse events reported. The data also showed very promising efficacy results in relation to BVCA.
  • a human placental growth factor (PlGF) neutralizing monoclonal antibody (THR-317).

Topline results from an exploratory Phase 2a study evaluating the efficacy and safety of intravitreal THR-317 when administered in combination with ranibizumab (Lucentis®), for the treatment of DME. Oxurion is further analyzing all data and is evaluating its future plans for THR-317 in relation to the treatment of DME.

In addition, THR-317 is being evaluated in a Phase 2 study for the treatment of Idiopathic Macular Telangiectasia Type 1 (MacTel 1), a rare disease that affects the macula and can lead to vision loss. First data from this study are expected towards the end of 2019.

  • a small molecule pan-RGD integrin antagonist (THR-687) being developed to treat a broad range of patients with diabetic eye disease. Phase 1 study with THR-687 completed patient enrolment in September 2019. Topline results from the Phase 1 study are expected by the end of 2019.

 

Patrik De Haes, M.D., CEO of Oxurion, said: “The positive topline results from a Phase 1 study confirm that THR-149, a potent plasma kallikrein inhibitor is well-tolerated and safe for intra-ocular use, and provides a rapid and sustained gain in BCVA. We believe that these positive findings demonstrate that THR-149 holds the potential to become a best-in-class PKal inhibitor for the treatment of DME. We are looking forward to the upcoming ‘late breaking’ podium presentation at the upcoming Euretina Congress in Paris and are currently in full preparation of a follow- up Phase 2 clinical trial evaluating THR-149 starting in early 2020.

“The recently reported topline results from an exploratory Phase 2 study evaluating THR-317 (anti-PlGF) in combination with ranibizumab for treatment of DME suggest that a combination therapy could play a certain role in the treatment of poor (or non) responders to prior anti-VEGF and with patients with a baseline BCVA of less or equal to 65 letters. We will continue to review and analyze these results, as well as last year’s reported positive Phase 1 results from the monotherapy study, before deciding on how to best position this program as we progress our overall clinical-stage portfolio of next-generation therapies for the treatment of DME. In making this decision, we will also take into account the outcome of the study evaluating THR-317 for treatment of MacTel1. The latter is expected for end of 2019.”

“Earlier this week we were happy to confirm that we have completed patient enrolment into our Phase 1 study evaluating the safety of our THR-687, a small molecule pan-RGD integrin antagonist for the treatment of DME. Topline data from this Phase 1 study will be reported before the end of 2019”, he continues.

“Our solid cash position of €67.6 million and prudent cash management will allow us to progress all of our ongoing and planned clinical and preclinical developments into 2021”, he concludes.

 

Diabetic Eye Disease - A Significant and Growing area of medical need

Diabetes is a major global healthcare problem with an estimated 425 million adults living with diabetes worldwide today. This number is expected to increase to over 625 million by 2045, according to the International Diabetes Federation.
Diabetic eye disease is caused by hyperglycemia (high blood glucose levels) associated with diabetes. If left unchecked hyperglycemia causes damage to the capillaries supplying blood, and hence oxygen, to the retina, the structure at the back of the eye responsible for vison.

Diabetic retinopathy (DR) is a serious, sight-threatening disease and the leading cause of vision loss among working-age adults. DR progresses from mild, non-proliferative to more severe or even proliferative stages (PDR). PDR, the more advanced stage of diabetic eye disease happens when the retina starts growing new fragile blood vessels, which often bleed into the vitreous leading to loss of vision.

It is estimated that there are 150 million diabetics with DR of which 50 million have vision threatening disease.

Diabetic macular edema (DME) is a severe complication of DR. DME is an accumulation of fluid in the macula – the part of the retina that controls detailed vision - due to leaking blood vessels. DME represents an area of major unmet medical need. The current standard of care, anti-VEGFs, have shown to deliver sub-optimal results. More than 50% of patients have an unsatisfactory early visual response with anti-VEGF therapy, and in many cases, they fail to achieve a clinically meaningful visual improvement.

 

Oxurion Clinical and Pre-clinical Development Update

THR-149 – a plasma kallikrein inhibitor for treatment of DME

Positive Topline Phase 1 Results with THR-149 for the treatment of DME – Phase 2 program expected to start in H1 2020

THR-149 is a novel plasma kallikrein inhibitor being developed for the treatment of DME.
THR-149 acts through inhibition of the Plasma Kallikrein-Kinin (PKaI-Kinin) system, which is considered a validated target for DME.
Topline data from the trial showed that THR-149 is well-tolerated and safe. No dose-limiting toxicities nor drug-related serious adverse events were reported at any of the dosages evaluated in the study.
The study also showed very promising results in relation to efficacy, in particular changes to the patient’s Best Corrected Visual Acuity (BCVA). A rapid onset of action was observed from Day 1, with an increasing average improvement in BCVA of up to 7.5 letters at Day 14.
Importantly, this activity was maintained with an average improvement in BCVA of 6.5 letters at Day 90 following a single injection of THR-149.
Oxurion is currently preparing the complete data analysis from this Phase 1 study with THR-149. The Company plans to present further clinical data from the study at Euretina in Paris (8 September), at the Retina Society Meeting in London (12 September) and during the upcoming AAO meeting of October in San Francisco.
The Company intends to start a Phase 2 development program with THR-149 in H1 2020.
This novel drug candidate was generated using Bicycle Therapeutics’ Bicycles® technology platform.

THR-317 – a Humanized mAb Against Human PlGF for the treatment of DME

THR-317 (anti-PlGF) is a recombinant humanized monoclonal antibody directed against the receptor-binding site of human placental growth factor (PlGF). THR-317 is being developed for the treatment of DME.
In 2018, positive Phase 1 data demonstrated the potential of THR-317 for treatment of diabetic macular edema in monotherapy. Topline results from that study showed strong safety data as well as first indications of clinical activity and durability of effect.
Following those positive results, the Company initiated a Phase 2a exploratory proof of concept study evaluating THR-317 in combination with ranibizumab (Lucentis®) for treatment of DME.

Mixed results from exploratory Phase 2a Clinical study evaluating THR-317 in combination with ranibizumab (Lucentis®) for treatment of DME

In August 2019, the Company announced the topline results from an exploratory 70 patient Phase 2a study evaluating the efficacy and safety of intravitreal THR-317 administered in combination with ranibizumab (Lucentis®) a VEGF inhibitor, for the treatment of DME.
The study showed that the combination did not produce an increase in BCVA in the overall population at Month 3.
Certain improvement in mean BCVA at Month 3 could be observed with the combination therapy in 2 pre-specified subgroups of interest:
o poor (or non) responders to prior anti-VEGF, and
o patients with poor vision - baseline BCVA ≤65 letters
Topline data confirmed that THR-317 in combination with ranibizumab is safe and well-tolerated.
Topline data from this exploratory Phase 2 combination study have been presented at the EURETINA conference in Paris on September 5, 2019.
Oxurion will further review and analyze the Phase 2 data before deciding on how to best position this program within its clinical-stage portfolio of next -generation therapies for the treatment of DME.

Phase 2 clinical study evaluating THR-317 for treatment of MacTel1

Oxurion is recruiting patients in a Phase 2 multi-center study evaluating the efficacy and safety of intravitreal THR-317 for the treatment of Macular Telangiectasia Type 1 (MacTel 1). MacTel 1 is a rare disease that affects the macula and can lead to vision loss. There is currently no effective treatment for MacTel 1.
This Phase 2 study plans to enroll a maximum of 10 patients with macular edema caused by MacTel 1. Each patient will each receive three 8mg intravitreal THR-317 injections over a period of 2 months. Efficacy and safety of the therapy will be assessed via functional and anatomic endpoints.
Initial results from this clinical study are anticipated by the end of 2019.

 

THR-687 – an integrin antagonist for treatment of DME

Phase 1 study evaluating THR-687, a novel pan-RGD integrin antagonist for the treatment of DME – recruitment completed

Oxurion is developing THR-687, a novel pan-RGD integrin antagonist, to preserve vision of a broad range of patients with diabetic eye disease. This wide-ranging potential is based on the hypothesis that integrin inhibition can address many of the processes that result in the pathological angiogenesis and vascular leakage that cause diabetic eye disease.
Oxurion is initially targeting THR-687 for the treatment of DME.
In September, Oxurion completed recruitment of a Phase 1 multicenter, dose escalation study evaluating the safety of a single intravitreal injection of THR-687 for the treatment of patients with DME. Twelve patients were enrolled in the study.
Initial results from this study are anticipated by the end of 2019.
At the EURETINA conference in Paris pre-clinical data will be presented showing that THR-687 potently inhibits ocular fibrosis. The presentation will be given on 6 September 2019.

Ocriplasmin Update

First introduced in early 2013, Jetrea® is a first-in-class pharmacological vitreolysis therapy approved for treatment of symptomatic vitreomacular adhesion or vitreomacular traction.
Over 30,000 patients have been treated with Jetrea® to-date with real world clinical data confirming that the drug is a safe and effective early treatment for a well identified group of patients suffering from symptomatic vitreomacular adhesion or vitreomacular traction.
As a company, we continue to recognize the value of providing this clearly differentiated treatment option to those patients who can benefit from it.
Oxurion remains committed to work alongside its stakeholders to provide Jetrea® to patients in an operationally efficient and cost-effective manner.

 

Oncurious - next generation immuno-oncology therapies Update

Oncurious – €1.0 million grant from Flanders Innovation and Entrepreneurship (VLAIO)

Oncurious, is developing next-generation immuno-oncology drugs targeting a broad spectrum of cancers. Oncurious is a majority owned subsidiary of Oxurion. The remainder of the shares in the company are owned by VIB, a leading life sciences research institute, based in Flanders, Belgium.
In June 2019, Oncurious received a project grant of close to €1.0 million from Flanders Innovation and Entrepreneurship (VLAIO) to support the further pre-clinical development of its pipeline of next generation cancer immunotherapies.
The non-dilutive grant funding will be used to identify a number of multi-specific biologics with distinct modes of action against immunomodulatory targets. These candidates will then be assessed in pre-clinical tumor models, both as monotherapies and in combination with standard of care treatment.

TB-403 for medulloblastoma

Recruitment of patients with Relapsed or Refractory Medulloblastoma is on-going in a US Phase 1/2a study with Oncurious’ lead program TB-403, a humanized monoclonal antibody against placental growth factor (PlGF).
The purpose of this study is to evaluate the safety and tolerability of TB-403 at the maximum tolerated dose in pediatric subjects with relapsed or refractory Medulloblastoma. TB-403 is being developed by Oncurious in conjunction with BioInvent International.

 

Financial Update

During the first six months of 2019, Oxurion booked €1.8 million Jetrea® revenues. This compared to €3.8 million for the same period in 2018. Based on these revenues, the company did proceed with the write-off of the remaining Jetrea® intangible assets.
For the first half of 2019, the group reported a gross profit of €0.6 million, compared to a gross profit of €2.6 million for the same period in 2018.
Oxurion’s R&D expenses were €12.0 million during the first half year of 2019. In the same period of 2018, the R&D expenses were €13.3 million. The 2018 figure included a milestone payment of €1.0 million related to the development of THR-149.
Selling and marketing expenses amounted to €3.4 million compared to €2.5 million in the corresponding period of 2018. The increase is the result of the return of ex-US Jetrea® rights.
General and administrative expenses were €3.3 million. This compares to €2.9 million in the first half of 2018.
For the first half of 2019, Oxurion reported a net loss of €33.3 million (or €-0.87 per share) composed of a €16.9 million Jetrea® remaining intangible asset write-off and €16.4 million current losses. Net, the €16.4 million loss compares to €15.2 million for the same period in 2018.
As of June 30, 2019, Oxurion had €67.6 million in cash, cash equivalents and investments. This compares with €85.1 million as of the end of December 2018.
