Summary

This is an investigator-initiated, prospective, single-center, open-label, single ascending dose clinical study. The study aims to evaluate the safety, tolerability, and potential efficacy of intravitreal injection of IGT001 in patients with retinitis pigmentosa across different dose groups. IGT001 is administered as a single intravitreal injection in the study eye under local anesthesia. Participants will be discharged on the day of treatment, provided that their visual acuity and intraocular pressure are close to baseline levels, and no clinically significant abnormalities in vital signs are observed compared to pre-injection values. The decision for discharge will be determined by the investigator's assessment.

Detailed description

The study's dose groups are divided based on concentration into four cohorts: the low-concentration cohort (0.5 × 10⁶ hRP-50 µL), the medium-concentration cohort (1.0 × 10⁶ hRP-50 µL), the high-concentration cohort (2.0 × 10⁶ hRP-50 µL), and the target-concentration cohort. Participants in the four cohorts will undergo a one-year follow-up as specified in the protocol. They will also be encouraged to participate in an additional one-year follow-up study to assess the long-term safety and tolerability of IGT001 after completing the main study.
