Brief summary

CADPT03A12001 is a prospective, multi-center study that is designed to follow all enrolled patients who have received treatment with OTQ923 for long-term safety and efficacy.

Detailed description

This study is monitoring patients treated with OTQ923, an investigational drug product of ex vivo genome-edited autologous hematopoietic stem and progenitor cells (HSPCs) that induces fetal hemoglobin (HbF) production, for a total of 15 years following infusion to monitor long-term safety and efficacy.

Design outcomes

Primary

MeasureTime frameDescription
Number of participants with delayed adverse events that are suspected to be related to previous OTQ923 therapyUp to 15 yearsNumber of participants with delayed adverse events including new secondary malignancies, new incidence or exacerbation of a prior autoimmune disorder, new incidence or exacerbation of a prior rheumatologic disorder, new hematologic disorder, and other adverse events considered to be related to OTQ923 therapy.

Secondary

MeasureTime frameDescription
Persistence of fetal hemoglobin expressionUp to 15 yearsAssessment of fetal hemoglobin (HbF) expression persistence in peripheral blood will be done by assessing hemoglobin fractionation
WBC chimerism in peripheral blood5 yearsConcern for loss of engraftment by monitoring the WBC chimerism annually. Modified white blood cells (WBCs) measured by droplet digital PCR (ddPCR) and NGS will be performed annually through year 5 with subsequent samples stored and run annually in the event of concern for loss of engraftment
