Experimental donor immune cells target Hard-to-Treat lymphoma
NCT ID NCT06285422
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase trial tests SC262, a therapy made from donor immune cells (CAR T cells) designed to attack a protein called CD22 on lymphoma cells. It is for people with non-Hodgkin's lymphoma that has come back or not responded to standard treatments. The main goal is to check safety, but researchers will also look for signs that the therapy shrinks tumors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- SC262 (a type of immune cell therapy called CAR T cells, made from donor cells)
- What this could lead to
- If it works, this could offer a new treatment option for people with non-Hodgkin's lymphoma that has not responded to other therapies.
- What could go wrong
- This is a very early (Phase 1) and small study (6 participants). It primarily tests safety, not effectiveness. The therapy may not work or could cause serious side effects.

Inclusion Criteria: 1. Male or Female Subject aged 18-80 years at the time of signing the informed consent 2. Histologic diagnosis of NHL (based on World Health Organization 2016 criteria) including: * LBCL, including Diffuse Large B Cell Lymphoma (DLBCL) not otherwise specified (NOS) (including DLBCL arising from indolent lymphoma), Primary Mediastinal Large B-Cell Lymphoma (PMBCL), High-Grade B-Cell Lymphoma (HGBCL), and Follicular Lymphoma (FL) Grade 3B * FL * Marginal Zone Lymphomas (MZL) * Mantle Cell Lymphoma (MCL) 3. Relapsed or refractory disease after no more than 1 prior CD19-directed CAR T cell therapy 4. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 5. At least 1 measurable (PET-positive) lesion per Lugano classification 6. Life expectancy ≥12 Weeks Exclusion Criteria: 1. Prior CD22-directed therapy including CD22-directed CAR T cell therapy or other CD22 -directed antibody or cell therapy (e.g., Natural Killer (NK) cell) 2. History of central nervous system (CNS) involvement of lymphoma within 1 year prior to enrollment. 3. Autologous hematopoietic stem cell transplantation (HSCT) within 3 months before treatment with Lymphodepleting (LD) chemotherapy (or allogeneic HSCT at any time) 4. Active autoimmune disease or any other diseases requiring immunosuppressive therapy or corticosteroid therapy (defined as \>10 mg/day prednisone or equivalent) 5. History or presence of CNS disorder, such as seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, or any autoimmune disease with CNS involvement, within 12 months of enrollment.
