About the Stellar Phase 1/2 Trial Stellar, or PQ-421a-001, is a first-in-human study of QR-421a in adults who have vision loss due to mutations in exon 13 of the USH2A gene and is conducted at expert sites in North America and Europe. It is a double-masked, randomized, 24-month study exploring the safety and efficacy of a single intravitreal injection of several dose levels of QR-421a and a control sham procedure into one eye. About QR-421a QR-421a is a first-in-class investigational RNA therapy designed to address the underlying cause of vision loss in Usher syndrome type 2 and non-syndromic retinitis pigmentosa (RP) due to mutations in exon 13 of the USH2A gene.
