Currently, there are limited treatment options capable of slowing disease progression for the majority of patients with RP. Preclinical studies have suggested that retinal inflammation, particularly the activity of inflammatory monocytes and macrophages, may contribute to photoreceptor degeneration. ULREA-PVS-NP is a novel intravenous formulation consisting of pitavastatin encapsulated in poly(lactic-co-glycolic acid) (PLGA) nanoparticles, developed to target inflammatory pathways associated with retinal degeneration. Preclinical studies demonstrated suppression of inflammatory monocyte\u002Fmacrophage activity and preservation of photoreceptors in animal models of RP.\n\nThis is a single-center, open-label, investigator-initiated Phase 1 study designed to evaluate the safety of intravenous ULREA-PVS-NP in adults with RP. The study consists of two parts. In Part 1, participants will receive a single intravenous infusion of ULREA-PVS-NP at escalating dose levels (2 mg, 4 mg, or 8 mg) to evaluate safety and tolerability. Following review of safety data, Part 2 will evaluate repeated administration of the highest dose considered safe in Part 1, given once every four weeks for a total of three administrations.\n\nThe primary objective is to evaluate the safety of ULREA-PVS-NP by assessing the incidence of adverse events. Secondary objectives include characterization of pharmacokinetic profiles, evaluation of changes in clinical laboratory tests and vital signs, and exploratory assessment of ophthalmologic outcomes and inflammatory biomarkers.",[48],"Retinitis Pigmentosa (RP)","NOT_YET_RECRUITING","2026-08-15",{"date":52,"type":53},"2026-08-19","ACTUAL",{"date":55,"type":42},"2026-09-15",{"date":57,"type":42},"2028-03-31",{"name":5,"class":6}]
