Boehringer Ingelheim is Initiating Phase IIa Study for the Development of a New Treatment for Diabetic Retinopathy - a Leading Cause of Vision-Loss
Sydney, Sep 8, 2017 AEST (ABN Newswire) - Boehringer Ingelheim and pharmaceutical research company Pharmaxis (
ASX:PXS) (PXSLY:OTCMKTS) announce that Boehringer Ingelheim is initiating the Phase IIa study ROBIN (Randomized study of Orally administered BI 1467335 in patients with Non-proliferative diabetic retinopathy without center-involved diabetic macular edema). This marks the beginning of the clinical development program for BI 1467335 in a second indication targeting a severe diabetes complication. An already ongoing Phase II clinical study program is investigating the compound in NASH. BI 1467335 is an oral inhibitor of amine oxidase, copper containing 3 (AOC3) (see Note 1 below).
- Diabetic retinopathy (DR) is the second severe metabolic complication on top of non-alcoholic steatohepatitis (NASH) to be investigated for BI 1467335, which was acquired from Pharmaxis
- Pharmaxis will receive EUR10 million milestone payment when the first patient is dosed in this 2nd indication Phase IIa study.
- Boehringer Ingelheim's holistic cardio metabolism R&D strategy reaches from risk factors, like obesity to complications, like NASH and DR
Diabetic retinopathy (DR) is the leading cause of vision-loss in adults aged 20-74. It progresses from mild nonproliferative diabetic retinopathy to moderate and severe nonproliferative diabetic retinopathy (NPDR), characterized by retinal hemorrhages and vascular changes in the retina, to proliferative diabetic retinopathy (PDR), characterized by the growth of new blood vessels on the retina. Diabetic Macular Edema (DME), characterized by retinal thickening from leaky blood vessels, can develop at all stages of retinopathy. Of an estimated 285 million people with diabetes mellitus worldwide, approximately one third have signs of DR and of these, a further one third of DR is vision-threatening DR (severe NPDR, PDR and DME). (see Note 2 below)
The ROBIN trial is a Phase IIa multi-centre, double-masked design in 100 patients with moderately severe to severe non-proliferative diabetic retinopathy (NPDR) without center-involved diabetic macular edema (CI-DME). The primary objectives are to establish proof of clinical principle and to evaluate the safety and tolerability of BI 1467335. Patients will be randomized to either BI 1467335 or to placebo for a 12-week treatment period with an additional 12-week follow-up period afterwards. A subsequent Phase IIb study will seek to confirm and extend these findings. (see Note 3 below)
Dr. Christopher Corsico, Chief Medical Officer Boehringer Ingelheim said, "We are delighted to advance BI 1467335 into Phase II clinical research for a second indication, targeting a severe complication of diabetes. This is important news for the millions of patients threatened by losing their vision. Boehringer Ingelheim is committed to developing novel treatments designed to address unmet medical need and improve public health and looks forward to studying this novel compound in NPDR patients".
Gary Phillips, Pharmaxis CEO said, "I'm delighted that our partner Boehringer Ingelheim has decided to pursue a second indication for the drug acquired from Pharmaxis in 2015. It will be very rewarding for the Pharmaxis team to see another group of patients benefit from our initial work. The deal structure negotiated with BI recognised the potential that the drug had in multiple indications so expanding the development plan to include diabetic retinopathy as well as NASH means that we will receive a EUR10m milestone payment when the first patient is dosed in the DR Phase IIa study and that all the potential development milestones in the deal (EUR418.5m /A$625m), would be payable to Pharmaxis should both indications be approved. Our belief that Boehringer Ingelheim would be a company that sought to maximize the potential of the drug was central to our choice of partner and this latest development reaffirms that view."
