Boehringer Ingelheim and Pharmaxis Ltd today announced the discontinuation of the development of anti-inflammatory AOC3 inhibitor BI 1467335 for the treatment of patients with moderate-severe non-proliferative diabetic retinopathy (NPDR). BI 1467335 was acquired from Pharmaxis in 2015 and Boehringer Ingelheim will now terminate the agreement.

In a Phase IIa trial in patients with moderate-severe NPDR, BI 1467335 met its primary endpoint in ocular safety with the treatment being well tolerated. Boehringer Ingelheim decided not to further develop BI 1467335 in this indication based on the lack of a clear efficacy signal and risk of dose dependent drug interactions of the compound in NPDR patients identified in another Phase I study.

Boehringer Ingelheim takes a holistic approach to the development of novel retinal disease therapies, targeting key mechanisms in the pathogenesis of retinal diseases. By leveraging existing expertise in oncology, inflammation, neurodegeneration, fibrosis and cardiometabolic diseases, the company is building a growing portfolio of next generation retinal therapy approaches in various stages of development up to Phase 2 in macular degeneration and diabetic retinal diseases.

Pharmaxis CEO, Gary Phillips said, “We understand Boehringer Ingelheim’s decision to stop development of BI 1467335 in NPDR based on the risk of dose dependent drug interactions at the dose level that was tested in the Phase IIa trial. Based on recent publications AOC3 remains an important clinical target. We will review the data collected in more detail to evaluate potential opportunities in other indications that already have supportive pre-clinical data and where the risk of drug interactions are of less concern. In the meantime, we look forward to the upcoming FDA decision on granting a marketing authorisation for Bronchitol in the US cystic fibrosis market and our focus remains on advancing our anti-cancer pan-LOX inhibitor program into a phase 2 myelofibrosis study following the recent IND approval.”


About the Phase IIa trial with BI 1467335 in NPDR (ROBIN study)

The Phase IIa trial (ClinicalTrials.gov Identifier: NCT03238963) was a Phase IIa multi-centre, double-masked design in 79 patients with moderately severe to severe non-proliferative diabetic retinopathy (NPDR) without center-involved diabetic macular edema (CIDME). The primary objective was to evaluate the safety and tolerability of BI 1467335. Secondary objective was the proportion of patients with a two step improvement in diabetic retinopathy severity score (DRSS). Patients were randomized to either BI 1467335 or to placebo for a 12-week treatment period with an additional 12-week follow-up period afterwards.


About Diabetic Retinopathy

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).
