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.
Interventions
There is no treatment allocation. Patients administered were OTQ923 while enrolled on the treatment protocol CADPT03A12101 (NCT04443907)

Eligibility
Inclusion criteria
1. Patients must have received gene therapy treatment from the parent treatment protocol (CADPT03A12101). 2. Patients must provide informed consent prior to their entry into this study.
Exclusion criteria
1\. Completion of less than 1 year of safety follow-up in the treatment protocol (CADPT03A12101).
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of participants with delayed adverse events that are suspected to be related to previous OTQ923 therapy | Up to 15 years | Number 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
| Measure | Time frame | Description |
|---|---|---|
| Persistence of fetal hemoglobin expression | Up to 15 years | Assessment of fetal hemoglobin (HbF) expression persistence in peripheral blood will be done by assessing hemoglobin fractionation |
| WBC chimerism in peripheral blood | 5 years | Concern 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 |
