Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 1/2, multi-center, randomized, sham-controlled, dose-escalation study evaluating ZM-02 in patients with advanced retinitis pigmentosa (RP).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Retinitis pigmentosa (RP) is the most common inherited retinal disease, characterized by progressive loss of visual function that can lead to severe visual impairment or blindness with no effective treatment.

This Phase 1/2 study is designed to evaluate the safety, tolerability, and preliminary efficacy of a single unilateral intravitreal injection of ZM-02 at escalating dose levels in patients with advanced RP. The study includes a sham-controlled design and will assess safety outcomes as well as multiple functional and structural measures of visual performance over long-term follow-up.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Male or female participants aged 6 to 60 years.
2. Clinical diagnosis of advanced retinitis pigmentosa (RP).
3. Best corrected visual acuity at or below the protocol-defined threshold in the study eye.
4. Presence of sufficient retinal structure in the study eye as determined by screening assessments.
5. Ability to understand and sign informed consent (and assent, when applicable).

Exclusion Criteria

1. Presence of other ocular conditions that could interfere with study assessments.
2. History of significant ocular surgery in the study eye within a protocol-defined period.
3. Active ocular infection or inflammation.
4. Clinically significant systemic disease that could increase study risk or interfere with assessments.
5. Positive screening for clinically significant infectious diseases, as defined in the protocol.
6. Pregnant or breastfeeding individuals.
7. Any condition that, in the investigator's judgment, would make the participant unsuitable for study participation.
