Raxone in LHON: Clinical development

Raxone has demonstrated its efficacy and safety profile in LHON in the largest clinical development program ever undertaken in LHON.1–7

The clinical development program included a double-blind, randomized, placebo-controlled study (RHODOS), an observational follow-up study (RHODOS-OFU), an Expanded Access Program (EAP), and a natural history case record survey (CRS).1,3–5,8–12 A number of additional clinical studies in multiple indications also support the safety profile of Raxone.9–12

The RHODOS trial

RHODOS is the first and only randomized, placebo-controlled clinical trial to be completed in LHON.3,4

What additional studies have been performed?

RHODOS-OFU
An observational follow-up study (RHODOS-OFU) was conducted in 58 patients who completed the RHODOS study and who were assessed after 30 months (median) off-treatment in order to assess whether treatment effects persisted over time.4 

Raxone Expanded Access Program (EAP)

  • The EAP provides insight into Raxone’s therapeutic potential in a real-world setting.5
  • Raxone was provided under the Named Patient Program (EU) or Treatment Investigational New Drugs (US) regulations.5
  • Enrollment was limited to patients presenting for treatment within 1 year of onset of symptoms.5
  • Data from 69 patients at 36 centers worldwide were analysed.
  • There will be no new patients enrolled in the EAP

Natural History Case Record Survey (CRS)

  • The CRS was established as a collaboration between Santhera Pharmaceuticals and the European Vision Institute Clinical Research Network (EVICR.net).8
  • Historically documented visual acuity (VA) data from existing medical records were collected from participating EVICR.net member centers and LHON-treating centers in the EAP across Europe and the US.13
