Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A Phase 1 Study Evaluating BAFFR-targeting CAR T Cells for Patients with Relapsed or Refractory B-cell Non-Hodgkin's Lymphoma (B-NHL)

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This phase I trial evaluates the side effects and best dose of BAFFR-CAR T cells in treating patients with B-cell Non-Hodgkin's Lymphoma (B-NHL) that has come back (recurrent) or does not respond to treatment (refractory). T cells are infection fighting blood cells that can kill cancer cells. The T cells given in this study will come from the patient and will have a new gene put in them that makes them able to recognize BAFFR, a protein on the surface of cancer cells. These BAFFR-specific T cells may help the body's immune system identify and kill BAFFR+ cancer cells.

* Autologous SCT \< 6 months before leukapheresis.
* Concurrent systemic steroids or chronic immunosuppressant use.
2. Disease-Specific Exclusions:

* Cardiac lymphoma involvement.
* Need for urgent therapy due to tumor-related complications (e.g., bowel obstruction).
3. Medical Conditions:

* Primary immunodeficiency.
* Cardiac conditions, including NYHA Class III/IV heart disease, arrhythmia, recent MI (≤ 6 months), stroke (≤ 6 months), or significant VTE (≤ 6 months).
* Neurologic conditions, including prior optic neuritis, CNS inflammatory diseases, or seizure disorders.
* History of malignancy, unless resected/treated with curative intent or in remission for ≥ 3 years.
* Uncontrolled systemic infections or active CNS lymphoma.
4. Pregnancy \& Breastfeeding: Females who are pregnant or nursing.
5. Other Considerations:

* Investigator-determined safety concerns.
* Potential noncompliance with study procedures.
