A Study to Evaluate Long-term Safety in Participants Who Have Participated in Other Luspatercept (ACE-536) Clinical Trials

A Phase 3b, open-label, single-arm, rollover study to evaluate the long-term safety of luspatercept, to the following participants: * Participants receiving luspatercept on a parent protocol at the time of their transition to the rollover study, who tolerate the protocol-prescribed regimen in the parent trial and, in the opinion of the investigator, may derive clinical benefit from continuing treatment with luspatercept * Participants in the follow-up phase previously treated with luspatercept or placebo in the parent protocol will continue into long-term post-treatment follow-up in the rollover study until the follow-up commitments are met * The study design is divided into the Transition Phase, Treatment Phase and Follow-up Phase. Participants will enter transition phase and depending on their background will enter either the treatment phase or the Long-term Post-treatment Follow-up (LTPTFU) phase * Transition Phase is defined as one Enrollment visit * Treatment Phase: For participants in luspatercept treatment the dose and schedule of luspatercept in this study will be the same as the last dose and schedule in the parent luspatercept study. This does not apply to participants that are in long-term follow-up from the parent protocol * Follow-up Phase includes: \- 42 Day Safety Follow-up Visit * During the Safety Follow up, the participants will be followed for 42 days after the last dose of luspatercept, for the assessment of safety-related parameters and adverse event (AE) reporting \- Long-term Post-treatment Follow-up (LTPTFU) Phase * Participants will be followed for overall survival every 6 months for at least 5 years from first dose of luspatercept in the parent protocol, or 3 years of post-treatment from last dose, whichever occurs later, or until death, withdrawal of consent, study termination, or until a subject is lost to follow-up. Participants will also be monitored for progression to AML or any malignancies/pre-malignancies. New anticancer or disease related therapies should be collected at the same time schedule Participants transitioning from a parent luspatercept study in post-treatment follow-up (safety or LTPTFU) will continue from the same equivalent point in this rollover study. The ACE-536-LTFU-001 rollover study will be terminated, and relevant participants will discontinue from the study when all participants fulfill 5 years on the study, including treatment and follow-up.

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.

Evaluation of Micro RNA-155 Expression in Relation to Alloantibody Formation in Transfusion-Dependent Patients

Transfusion-dependent patients, particularly those with β-thalassemia major, require lifelong regular red blood cell (RBC) transfusions to maintain adequate hemoglobin levels and prevent severe anemia. Although transfusion therapy significantly improves survival and quality of life, it is associated with several immunological complications, the most important of which is red cell alloimmunization. Alloimmunization occurs when the recipients immune system recognizes foreign antigens on donor RBCs and produces alloantibodies against them, which may lead to hemolytic transfusion reactions, difficulty in finding compatible blood and increased transfusion requirements (1). The incidence of RBC alloimmunization in transfusion-dependent patients varies widely but remains a major clinical challenge in transfusion medicine (2). Recent advances in molecular hematology have highlighted the importance of microRNAs (miRNAs) in regulating immune responses and hematopoiesis. MicroRNAs are small non-coding RNA molecules that regulate gene expression at the post-transcriptional level and play a key role in both innate and adaptive immunity (3). Among them, microRNA-155 (miR-155) has emerged as a critical regulator of inflammatory pathways, antigen presentation, and lymphocyte activation. It modulates immune cell differentiation and cytokine production, thereby influencing immune responses to foreign antigens (4, 5). In patients with β-thalassemia, miR-155 is also implicated in erythropoiesis and ineffective red cell production, suggesting its involvement in both hematologic and immunologic pathways of the disease. Increased expression of miR-155 has been reported in thalassemic erythroid cells and is associated with altered erythroblast proliferation and differentiation (6). Importantly, recent studies suggest that miR-155 may contribute to the development of alloimmunization in transfusion-dependent patients.

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.

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.

Plasticizer Exposure and Its Consequences on Health

Plasticizers are chemicals commonly found in many everyday items, from food packaging to medical equipment. Although they are pervasive in our daily lives, researchers still don't have a clear picture of their long-term effects on human health. Evidence suggests that these substances might disrupt various biological functions such as the immune system, the balance of gut bacteria, hormone regulation, and brain processes. While some studies have linked plasticizer exposure to health issues, definitive data from human studies are still lacking. The PEACH study aims to bridge these knowledge gaps by investigating how plasticizers affect human health. The study focuses on understanding how these chemicals are absorbed, distributed, and accumulated in the body across different groups of patients. The investigators are particularly interested in how plasticizers influence gut microbiota and the functionality of immune cells, as well as their effects on neurotransmitters involved in brain function. A combination of patient data, systems biology, and laboratory models will be used to thoroughly assess the biological impacts of plasticizers. Advanced techniques such as mass spectrometry will aid in studying toxicokinetic properties, sequencing technologies will be used to examine immune effects, and radiouptake assays will be employed to explore interactions with neurotransmitter transport. This comprehensive methodology will provide new insights into the effects of both short-term and long-term exposure to plasticizers. The PEACH study introduces innovative methods to the field, aiming to create a robust model for understanding how plasticizer compounds behave in the human body. It employs state-of-the-art techniques to assess the dynamics of these chemicals, marking a significant advancement in environmental health research.
