Vamorolone

January 16, 2025 – Santhera Pharmaceuticals (SIX: SANN) announces that Idorsia Pharmaceuticals has entered into a royalty monetization agreement with the R-Bridge Healthcare Fund in relation to AGAMREE® (vamorolone). Idorsia has also recently exercised outstanding warrants held in Santhera on a cashless basis, reinforcing its position as a major shareholder in the Company. Idorsia transfers rights to royalties and milestones for AGAMREE (vamorolone) to R-Bridge Healthcare Fund through a monetization agreement In 2020, Idorsia’s license, collaborative development, and commercialization agreement with ReveraGen BioPharma for AGAMREE was transferred in its entirety to Santhera. As part of this agreement, Idorsia is entitled to development and sales milestones, as well as low single-digit percentage royalties on net sales of AGAMREE. Under a royalty monetization agreement finalized in December 2024, Idorsia received a USD 30 million payment from the R-Bridge Healthcare Fund in exchange for the rights to receive future AGAMREE royalties and milestones, up to a specified cap. Once this cap is reached, the entitlement to AGAMREE royalties and milestones will revert back to Idorsia. The R-Bridge Healthcare Fund is managed by CBC Group, a global healthcare-dedicated asset management firm. CBC has previously provided funding to Santhera and its decision to acquire Idorsia’s AGAMREE royalties further reflects its confidence in Santhera’s development and commercialization efforts. Dr. Michael Keyoung, Senior Managing Director & Head of Private Credit and Royalty at CBC Group commented: “We are pleased to strengthen our ties with Santhera as they continue to advance AGAMREE into the markets. Our decision to acquire the AGAMREE royalties from Idorsia reflects our deep confidence in Santhera and AGAMREE’S potential to help treat children and adolescent patients with DMD globally.” Idorsia has exercised 221,161 warrants outstanding with Santhera at an exercise price of CHF 9.043 per share and an expiry date of January 9, 2025. By mutual agreement, the exercise was executed on a cashless basis, reflecting the value differential between the exercise price and the volume weighted average price of CHF 14.2598 on January 9, 2025, of Santhera’s shares. As a result, 80,909 Santhera shares were issued to Idorsia. This transaction ensures that Idorsia maintains its 10% shareholding in Santhera, highlighting its ongoing support and alignment with Santhera’s long-term growth strategy. Andrew Smith, CFO of Santhera, added: “CBC is a trusted and valued partner to Santhera, and this transaction further affirms their confidence in our team and strategy. Additionally, Idorsia’s decision to maintain its shareholding underscores the support for Santhera and its ambition to deliver improvements in care for patients with rare diseases.” AGAMREE is a novel drug with a mode of action based on binding to the same receptor as glucocorticoids but modifying its downstream activity. Moreover, it is not a substrate for the 11-β-hydroxysteroid dehydrogenase (11β-HSD) enzymes that may be responsible for local drug amplification and corticosteroid-associated toxicity in local tissues [1-4]. This mechanism has shown the potential to ‘dissociate’ efficacy from steroid safety concerns and therefore AGAMREE is positioned as a dissociative anti-inflammatory drug and an alternative to existing corticosteroids, the current standard of care in children and adolescent patients with DMD [1-4]. In the pivotal VISION-DMD study, AGAMREE met the primary endpoint Time to Stand (TTSTAND) velocity versus placebo (p=0.002) at 24 weeks of treatment and showed a good safety and tolerability profile [1, 4]. The most commonly reported side effects were cushingoid features, vomiting, weight increase and irritability. Side effects were generally of mild to moderate severity. Currently available data show that AGAMREE, unlike corticosteroids, has no restriction of growth [5] and no negative effects on bone metabolism as demonstrated by normal bone formation and bone resorption serum markers [6].

Santhera has begun launch preparations for AGAMREE® in UK with first sales expected in this quarter January 16, 2025 – Santhera Pharmaceuticals (SIX: SANN) announces that the National Institute for Health and Care Excellence (NICE) has issued positive Final Guidance that recommends AGAMREE® (vamorolone) for use in the National Health Service (NHS) in England, Wales and Northern Ireland for the treatment of Duchenne muscular dystrophy (DMD) in patients 4 years of age and older. This follows confirmation that no appeals were received against the Final Draft Guidance (FDG) recommendation announced on December 10, 2024. Following this, Santhera has already started launch preparations for AGAMREE in the UK and expect first sales in this quarter. AGAMREE is the first and only medicinal product for DMD to have received full approval in the EU, US, and UK. This recommendation follows the Medicines and Healthcare products Regulatory Agency’s (MHRA) approval of AGAMREE on January 11, 2024, which, alongside the European Medicines Agency (EMA), acknowledged clinically important tolerability benefits with regards to maintaining normal bone metabolism, density, and growth compared to standard of care corticosteroids, alongside similar efficacy from clinical trials. The Final Guidance is available on the NICE website: www.nice.org.uk/guidance/TA1031 AGAMREE is a novel drug with a mode of action based on binding to the same receptor as glucocorticoids but modifying its downstream activity.
