Study summary

The current study is a non-interventional long-term safety follow-up of the subjects who completed STARLIGHT, in accordance with FDA guidance on recipients of human gene therapy products.

Read the detailed description

This study is designed to follow subjects with Stargardt Disease (SD) previously enrolled in study NTXMCO-004 (STARLIGHT, NCT05417126). In that study, all 6 enrolled subjects received MCO-010, an ambient light-activated, Multi-Characteristic Opsin (MCO) transgene in an adeno-associated virus serotype 2 (AAV2) vector via intravitreal injection (IVT). MCO-010 has the potential to restore vision irrespective of the underlying gene mutation, and because it is directed at bipolar retinal cells, intact photoreceptors are not required. Further details on MCO-010 and the underlying disease under investigation are included in the protocol for STARLIGHT and are not repeated herein

What researchers measure

Primary outcomes

  1. Assessment of the long-term safety profile of a single intravitreal injection of MCO-010

    Assessment of incidences, nature, and severity of treatment emergent adverse events (TEAEs), serious adverse events (SAEs); intraocular inflammation graded through ocular exam; clinical examination, and intraocular pressure.

    Time frame: 204 weeks

Secondary outcomes

  1. Evaluation of the long-term effects on visual acuity of a single intravitreal injection of MCO-010; 1.2E11 gc/eye

    Change from baseline in BCVA over time in the study eye and fellow eye

    Time frame: 204 weeks

  2. Exploration of the long-term impact of MCO-010 on retinal anatomy

    Assessment of fundus photography and optical coherence tomography (OCT) outcomes over time

    Time frame: 204 weeks

  3. Assessment of the long-term durability of MCO-010 induced on gene reporter expression

    Change from baseline of fundus fluorescence intensity of reporter (mCherry) over time in the study eye and fellow eye

    Time frame: 204 weeks
