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.
Leber's hereditary optic neuropathy (LHON) is a rare mitochondrial genetic disorder characterized by optic nerve atrophy due to the degeneration of retinal ganglion cells, which leads to acute visual loss. Males are more likely to develop optic neuropathy than women. They experience blurring or clouding of vision in one eye. The fellow eye develops similar symptoms sequentially with a delay of weeks. This sudden vision loss has devastating consequences on the life course of young men, with the impact of LHON on their quality of life and loss of independence. Yet, data describing the impacts of LHON on the life-course of patients is lacking, with very little data available in the literature. This study aims to understand the life of patients living with LHON disease through the analysis of the impact of LHON on the quality of life and loss of independence of patients living in France and to accurately describe the consequences of the disease on their social, familial and professional life.
The objective of this clinical study is to evaluate the safety and efficacy of NR082 in the treatment of LHON caused by mitochondrial ND4 gene mutation. This study will enroll subjects aged ≥ 18 years old and ≤ 75 years old to receive a single unilateral intravitreal (IVT) injection of NR082 to evaluate its safety and efficacy. The clinical manifestations of all subjects are to be reduced visual acuity caused by LHON associated with ND4 mutation, with laboratory test showing G11778A 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.
The development of new oculometry techniques allows fine and dynamic measurements of pupillary diameter and use in routine clinical practice. The preliminary results obtained with innovative devices on healthy sjuets make it possible to envisage a clinical study on a population of patients suffering from retinal pathologies. This is a "proof of concept" study, which, if the expected results are confirmed, will make it possible to consider a study on a larger population, as well as the industrial development of a commercial device.
