ALS20-101 Lentiviral Gene Therapy for Beta Thalassemia

The main goal of this study is to find out if the blood disorder called transfusion-dependent beta thalassemia can be safely treated by modifying blood stem cells. This is done by collecting blood stem cells from the subject, modifying those cells, adding a healthy beta globin gene, and then giving them back to the subject. It is hoped that these modified cells will decrease the need for blood transfusions. The gene modified blood stem cells are called CHOP-ALS20 ("study drug"). This experimental gene therapy has not been tried on human beings before and is not FDA approved.

Hematopoietic Stem Cell BCL11A Enhancer Gene Editing for Severe β-Hemoglobinopathies

A promising approach for the treatment of genetic diseases is called gene therapy. Gene therapy is a relatively new field of medicine that uses genetic material (mostly DNA) from the patient to treat his or her own disease. In gene therapy, the investigators introduce new genetic material in order to fix or replace a diseased gene, with the goal of curing the disease. The procedure is similar to a bone marrow transplant, in that the patient's malfunctioning blood stem cells are reduced or eliminated using chemotherapy, but it is different because instead of using a different person's (donor) blood stem cells for the transplant, the patient's own blood stem cells are given back after the new genetic material has been introduced into those cells. This approach has the advantage of eliminating any risk of Graft-Versus-Host Disease (GVHD), reducing the risk of graft rejection, and may also allow less chemotherapy to be utilized for the conditioning portion of the transplant procedure. The method used to fix or replace a diseased gene is called gene editing. A person's own cells are edited using a specialized biological medicine that has been formulated for use in human beings. Fetal hemoglobin (HbF) is a healthy, non-sickling kind of hemoglobin. Investigators have recently discovered a gene called BCL11A that is very important in the control of fetal hemoglobin expression. Increasing the expression of this gene in sickle cell patients could increase the amount of fetal hemoglobin while simultaneously reducing the amount of sickle hemoglobin in their blood, and therefore potentially cure the condition.

Study of Safety & PK of Luspatercept (ACE-536) in Pediatric Participants With Beta (β)-Thalassemia

This is a Phase 2a study to evaluate the safety and pharmacokinetics (PK) of luspatercept in pediatric participants with β-thalassemia. The study will be conducted in 2 parts for both transfusion-dependent (TD) and non-transfusion-dependent (NTD) β-thalassemia participants: TD Part A will be in adolescent participants aged 12 to \<18 years with two dose escalation cohorts, followed by a dose expansion cohorts. NTD Part A will be conducted in the same age group participants as TD Part A with dose confirmation and expansion cohorts. After Part A TD participants have completed at least one year of treatment, all available safety data from Part A adolescent participants will be evaluated before initiating TD and NTD Part B in the age group from 6 to \<12 years old. Part B will consist of two dose escalation cohorts for TD and two dose escalation cohorts for NTD. Upon completion of the Treatment Period, participants of any cohort who are benefiting from the study treatment, will be offered the opportunity to continue luspatercept treatment in the Long-term Treatment Period for up to 5 years from their first dose. Participants who discontinue study treatment at any time will continue in the Posttreatment Follow-up Period for at least 5 years from their first dose of luspatercept, or 3 years from their last dose, whichever occurs later, or until they withdraw consent/assent, are lost to follow-up, or the End of Trial, whichever occurs first.

Data will be collected through clinical interviews and medical records and analyzed using(Statistical Package for the Social Sciences. This project aims to enhance beta thalassemia treatment strategies, focusing on reducing transfusion dependency and improving patient quality of life.

Early Check: Expanded Screening in Newborns

Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to participate, equating to over 120,000 eligible infants a year. Over 95% of participants are expected to screen negative. Newborns who screen positive and their parents are invited to additional research activities and services. Parents can enroll eligible newborns on the Early Check electronic Research Portal. Screening tests are conducted on residual blood from existing newborn screening dried blood spots. Confirmatory testing is provided free-of-charge for infants who screen positive, and carrier testing is provided to mothers of infants with fragile X. Affected newborns have a physical and developmental evaluation. Their parents have genetic counseling and are invited to participate in surveys and interviews. Ongoing evaluation of the program includes additional parent interviews.

FLOWER: Following Longitudinal Outcomes With Epidemiology for Rare Diseases

FLOWER is a completely virtual, nationwide, real-world observational study to collect, annotate, standardize, and report clinical data for rare diseases. Patients participate in the study by electronic consent (eConsent) and sign a medical records release to permit data collection. Medical records are accessed from institutions directly via eFax or paper fax, online from patient electronic medical record (EMR) portals, direct from DNA/RNA sequencing and molecular profiling vendors, and via electronic health information exchanges. Patients and their treating physicians may also optionally provide medical records. Medical records are received in or converted to electronic/digitized formats (CCDA, FHIR, PDF), sorted by medical record type (clinic visit, in-patient hospital, out-patient clinic, infusion and out-patient pharmacies, etc.) and made machine-readable to support data annotation, full text searches, and natural language processing (NLP) algorithms to further facilitate feature identification.

Adherence of Beta Thalssemia Patients to Oral Chelation Therapy

The β-thalassemias are a group of inherited disorders of hemoglobin (Hb) synthesis characterized by chronic anemia of varying severity. The degree of anemia relies on several genetic and environmental factors and determines the need for regular transfusion therapy. It is now common practice to classify patients as having transfusion dependent β-thalassemia (TDT) or non-transfusion-dependent β-thalassemia (NTDT). Regarding geographical distribution of β-thalassemia, it prevails more in countries on the Mediterranean, South east of Asia and in the east of Europe. In Egypt, it is the most common cause of chronic blood loss: One thousand cases are recorded annually for every 1.5 million live births the disease prevalence is equal to1000 cases per 1.5 million live births (Ghazala et al., 2021). The only curative treatment for thalassemia currently is a bone marrow transplant. However, it is restricted to only a few patients due to the non-availability of an HLA-matched donor and high cost. Thus, most patients receive regular blood transfusions accompanied by iron chelation therapy (ICT) as the standard of care. The ideal management of a patient with transfusion-dependent thalassemia (TDT) requires a multidisciplinary therapeutic approach. The main iron chelating agents include deferoxamine (DFO), deferiprone (DFP), and deferasirox (DFX). Due to poor oral bioavailibility, DFO is the only chelator that must be administered subcutaneously or intravenously up to once a day; DFP and DFX may be administered orally up to three times a day. The known side effects associated with each chelator include infusion reactions in DFO, gastrointestinal distress, agranulocytosis in DFP, and transaminitis in DFP and DFX.
