Current and Future Landscape in Genetic Therapies for Leber Hereditary Optic Neuropathy.
(PubMed, Cells)
- "In 2015, an antioxidant idebenone (Raxone) received European marketing authorisation to treat visual impairment in patients with LHON, and since then it was introduced into clinical practice in several European countries. This manuscript discusses the phenotype and genotype of the LHON disease with complexities and peculiarities such as incomplete penetrance and gender bias, which have challenged the therapies in development emphasising the most recent use of gene therapy. Furthermore, we review the latest results of the three clinical trials based on adeno-associated viral (AAV) vector-mediated delivery of NADH dehydrogenase subunit 4 (ND4) with mitochondrial targeting sequence, highlighting the differences in the vector design and the rationale behind their use in the allotopic transfer."

Results in m.G3460A eyes were limited by an unexpectedly mild disease course in the NH cohort; further study of the impact of idebenone treatment in this subgroup is needed. _x000D_ _x000D_ _x000D_"

(SOE 2023)
- P4 | "In eyes of patients ≥18 years, VA improvement at Month 24 was greater in idebenone-treated eyes versus those in the NH cohort. Treatment benefit was particularly apparent in the chronic phase, corresponding to >10 additional letters on the ETDRS chart. In chronic eyes from patients <18 years, a non-significant trend was observed in favor of idebenone; in subacute/dynamic eyes spontaneous VA recovery was unexpectedly high in the NH cohort."

Santhera Concludes Agreement with French Authorities on Raxone Reimbursement and Plans to Submit a Request for an Early Access Program for Vamorolone
(GlobeNewswire)
- "Santhera Pharmaceuticals...announces that it has secured a final reimbursement agreement with the French authorities related to Raxone® (idebenone) for the treatment of Leber's hereditary optic neuropathy (LHON) and sales are expected to resume shortly....Santhera will make repayments in the total amount of approximately EUR 25 million, with 30% due around mid-2024 and the remainder one year later....The first payment is currently expected to be covered by sales generated until mid-2024, while the majority of the second payment will be covered by sales beyond mid-2025....Earlier in January, Santhera announced FDA acceptance of the new drug application (NDA) for vamorolone for DMD for filing. Subject to approval, Santhera plans to launch vamorolone in the U.S. in Q4-2023. European marketing authorization application (MAA) for vamorolone has been validated and is under review by the EMA which could pave the way for a first EU launch in late 2023."

Molecular profiling of advanced pancreatic cancer (PC) patients from a phase I/II study using circulating tumor DNA.
(ASCO 2017)
- P2; " Plasma samples were banked from patients enrolled in the previously reported Phase Ib/II trial of gemcitabine with placebo or vismodegib (NCT01064622; Catenacci et al JCO 2015). ctDNA analysis of this cohort of banked PC plasma samples described the landscape of genomic aberrations at baseline and over time, including rare but potentially important actionable events including ERBB2 and FGFR2 amplifications and IDH1 mutation. We demonstrate a sensitive method for re-analysing trial outcomes, despite limiting plasma volume and time lapse since samples were collected."
