FREE EXCERPT

Santhera Pharmaceuticals and Idorsia Ltd have entered into an agreement under which Santhera will acquire the option to exclusively in-license, by way of sub-license, the first-in-class dissociative steroid vamorolone in all indications and all countries worldwide except Japan and South Korea. Initial clinical data suggest that vamorolone has the anti-inflammatory efficacy of steroids with reduced steroid-associated safety concerns, which would represent a significant improvement over current standard of care glucocorticoid therapy in patients with Duchenne muscular dystrophy (DMD), vamorolone's lead indication.

Vamorolone is a first-in-class drug candidate that binds to the same receptors as glucocorticoids but modifies the downstream activity of the receptors. This has the potential to 'dissociate' efficacy from typical steroid safety concerns and therefore could replace existing glucocorticoids, the current standard of care in children and adolescent patients with DMD. There is significant unmet medical need in this patient group as high dose glucocorticoids have severe systemic side effects, which limit long-term usage.

Vamorolone was discovered by US-based ReveraGen BioPharma Inc. and has been developed with participation in funding and design of studies by 12 international non-profit foundations, the US National Institutes of Health, the US Department of Defense and the European Commission's Horizon 2020 program. Actelion had acquired an option to license the product in 2016. This option was subsequently transferred to Idorsia following the acquisition of Actelion by Johnson & Johnson in 2017.

Following single and multiple ascending dose clinical pharmacology studies (VBP15-001) in healthy volunteers [1] vamorolone completed a Phase IIa study (VBP15-002) in 48 boys with DMD aged 4 to

The ongoing Phase IIb VISION-DMD study (VBP15-004) builds on the available promising preliminary safety and efficacy data from Phase IIa and is designed to bridge exploratory biomarker data to clinical outcomes. This pivotal study will enroll approximately 120 boys aged 4 to

The study is being conducted at approximately 30 sites across North America, Europe, Israel and Australia. Enrolment, which began in August 2018, is expected to take about 12 months, with a total study duration of about 24 months. If successful, the data filing with health authorities in the US is anticipated by the end of 2020 and in the EU in 2021. Vamorolone has received Orphan...
