Filter by:The objective of this clinical study is to evaluate the safety, tolerability and preliminary efficacy of NFS-02 in the treatment of LHON caused by mitochondrial ND1 gene mutation. This study will enroll subjects aged ≥ 18 years old and ≤ 75 years old to receive a single unilateral intravitreal (IVT) injection of NFS-02 to evaluate its safety, tolerability and preliminary efficacy. The clinical manifestations of all subjects are to be reduced visual acuity caused by LHON associated with ND1 mutation, with laboratory test showing G3460A mutation (a CLIA-certified laboratory) and reduced visual acuity lasted for > 6 months and < 10 years.
The objective of this clinical study is to select the optimal dose and evaluate the safety and efficacy of NR082 in treatment of LHON caused by mitochondrial ND4 gene mutation. Part 1 (Phase 1/2) is a safety dose-finding study, which will enroll subjects aged ≥ 18 years old and ≤ 75 years old to receive a single unilateral intravitreal (IVT) injection of NR082 to observe its safety and efficacy. In Part 2 (Phase 3) of the clinical study, the dose recommended after the end of Part 1 is used to further verify the safety and efficacy of the study drug. Part 2 of the study is divided into the safety run-in phase and the randomized, double-blind and control study. Subjects aged ≥ 12 years and ≤ 75 years will be enrolled in the Part 2. The run-in phase will enroll 6 evaluable subjects. After monitoring for at least 6 weeks, if no new safety signals are observed, the clinical trial will enter the randomized, double-blind and control study phase upon approval by the Safety Review Committee(SRC). The clinical manifestation of all subjects is reduced visual acuity caused by LHON associated with ND4 mutation, and central laboratory test showed G11778A mutation (a CLIA-certified laboratory), while the reduced visual acuity lasted for > 6 months and < 10 years.
This study investigates a new technology to assess the structure and function inside the eye. Retinal imaging of subjects with inner and outer retinal defects to detect areas of abnormal structure and function compared to other visual function tests.
This study will evaluate the use of autologous bone marrow derived stem cells (BMSC) for the treatment of retinal and optic nerve damage or disease.
The Leber Hereditary Optic Neuropathy is a genetic disorder caused by maternal transmission of mitochondrial DesoxiroboNucleid Acid mutations. It is manifested by a rapidly progressive blindness, profound, due to atrophic optic nerve. The visual loss is primarily unilateral bilateralisation taking place in the vast majority of cases in weeks or months. The neuro-cardio-protective properties of cyclosporine (and its analogs specifically targeting the anti-apoptotic mechanisms) are particularly promising. The investigators hypothesis is that cyclosporine may limit apoptosis during the acute phase of the disease process and would limit the loss of visual acuity and improve the visual prognosis of these patients.
