What side effects are associated with this type of intervention?

Common treatments for Acute Lymphoblastic Leukemia (ALL), including CAR T cell therapies targeting CD19, are associated with significant side effects. These include cytokine release syndrome (CRS), which can range from mild to severe, neurotoxicity, prolonged cytopenias, increased risk of infections, and hypogammaglobulinemia. Traditional chemotherapy regimens, such as those involving cytarabine and anthracyclines, can cause myelosuppression, cardiotoxicity, and gastrointestinal disturbances.

What prior FDA approvals exist?

The FDA has approved several CAR T-cell therapies for the treatment of Acute Lymphoblastic Leukemia (ALL) that target CD19-expressing B cells. Notably, tisagenlecleucel (Kymriah) was the first CAR T-cell therapy approved for pediatric and young adult patients with refractory or relapsed B-cell ALL. Another significant approval is for brexucabtagene autoleucel (Tecartus), which is used for relapsed or refractory mantle cell lymphoma but also targets CD19. These therapies work by modifying a patient's T cells to express a receptor that targets and eliminates CD19-positive B cells, similar to the UCD19 CAR T cells being studied.

What other types of research exist?

Promising novel alternatives to UCD19 CAR T cells for ALL patients include: 1) Bispecific T-cell engagers (BiTEs) such as blinatumomab, which targets CD19 and CD3 to engage T cells in killing B cells. 2) CAR T cells targeting other antigens like CD22 (e.g., m971 CAR T cells). 3) Antibody-drug conjugates (ADCs) like inotuzumab ozogamicin, which targets CD22. 4) Novel small molecule inhibitors and immunomodulatory drugs that are currently under investigation in clinical trials.

Study Summary

This trial is testing a new cancer treatment involving CAR T cells (a type of immune cell) for people with B-ALL (a type of blood cancer) who are in first complete remission with minimal residual disease. The trial will enroll 10 patients and assess them for safety and tolerability of the treatment.

Who is the study for?

Adults with B-cell ALL in first complete remission but still showing minimal residual disease can join this trial. They must be fit enough for treatment (ECOG ≤ 2), have adequate organ function, and not be pregnant or planning pregnancy. Excluded are those with previous CAR T therapy, active CNS leukemia, uncontrolled infections, HIV/hepatitis B/C, certain heart conditions, or a history of other cancers within 3 years.Check my eligibility

What is being tested?

The trial is testing UCD19 CAR T cell therapy's safety and effectiveness in adults with acute lymphoblastic leukemia who are in remission but have some remaining cancer cells. It involves collecting patients' immune cells, modifying them to target cancer cells better and then infusing them back into the patient after chemotherapy.See study design

What are the potential side effects?

Potential side effects include reactions related to immune system activation such as fever and fatigue (cytokine release syndrome), neurological issues like confusion or seizures (neurotoxicity), blood cell count changes leading to increased infection risk, and infusion-related reactions.

Other Research

The most common treatments for Acute Lymphoblastic Leukemia (ALL) include chemotherapy, targeted therapy, and immunotherapy. Chemotherapy uses cytotoxic drugs to kill rapidly dividing cells, which is essential for eliminating leukemic cells. Targeted therapies, such as tyrosine kinase inhibitors (TKIs), inhibit specific proteins involved in cancer cell growth and survival, providing a more precise treatment. Immunotherapy, including CAR T-cell therapy like UCD19 CAR T cells, involves engineering a patient's T cells to express chimeric antigen receptors that target and destroy CD19-expressing B cells, which are prevalent in B-ALL. This targeted approach is crucial for ALL patients as it offers a highly specific and effective method to eradicate leukemic cells, potentially improving outcomes and reducing the likelihood of relapse.
