Liestal, Switzerland, August 31, 2017 - Santhera Pharmaceuticals (SIX: SANN) announces approval of Raxone^® (idebenone) for the treatment of visual impairment in adolescent and adult patients with Leber's hereditary optic neuropathy (LHON) from the Ministry of Health Israel - the first approval for Raxone in LHON outside Europe.

Following the European Commission's marketing authorization for Raxone, the first approved treatment in LHON and the first approved treatment for a mitochondrial disease, the Ministry of Health Israel granted Raxone a marketing authorization for the treatment of visual impairment in adolescent and adult patients with LHON.¹

"We are pleased that Raxone has received marketing authorization for the treatment of LHON in Israel, the first approval for the product outside of Europe," said Giovanni Stropoli, Chief Commercial Officer Europe & ROW at Santhera. "As part of our strategy to provide treatment to patients in Europe and beyond, we have signed a collaboration agreement with Megapharm Ltd., a leading Israeli private pharma marketing company, who is committed to making Raxone available to patients with LHON in Israel."

About Leber's Hereditary Optic Neuropathy and the Therapeutic Use of Raxone
Leber's hereditary optic neuropathy (LHON) is a heritable genetic disease causing blindness. The disease presents predominantly in young, otherwise healthy adult males as rapid, painless loss of central vision, usually leading to permanent bilateral blindness within a few months of the onset of symptoms. About 95% of patients harbor one of three pathogenic mutations of the mitochondrial DNA, which cause a defect in the complex I subunit of the mitochondrial respiratory chain. This defect leads to decreased cellular energy (ATP) production, increased reactive oxygen species (ROS) production and retinal ganglion cell dysfunction, which cause progressive loss of visual acuity and blindness.
Raxone (idebenone), a synthetic short-chain benzoquinone and a cofactor for the enzyme NAD(P)H:quinone oxidoreductase (NQO1), circumvents the complex I defect, reduces and scavenges ROS, restores cellular energy levels in retinal ganglion cells and promotes recovery of visual acuity.
Raxone is an oral medication, authorized at a daily dose of 900 mg (given as 2 tablets three times a day with food), for the treatment of visual impairment in adolescent and adult patients with LHON.
