Non Hodgkin Lymphoma Clinical Trial

NKTR-255 in Combination With CAR-T Cell Therapy for the Treatment of Relapsed or Refractory Large B-cell Lymphoma

Summary

This phase Ib trial studies the effects of NKTR-255 in combination with chimeric antigen (CAR)-T cell therapy and to see how well they work in treating patients with large B-cell lymphoma that has come back (relapsed) or does not respond to treatment (refractory). NKTR-255 is an investigational IL-15 receptor agonist designed to boost the immune system's natural ability to fight cancer. T cells are infection fighting blood cells that can kill tumor cells. Lisocabtagene maraleucel is a CAR-T cell product that consists of genetically engineered T cells, modified to recognize CD19, a protein on the surface of cancer cells. These CD19-specific T cells may help the body's immune system identify and kill CD19-positive cancer cells. Giving NKTR-255 together with lisocabtagene maraleucel may work better in treating large B-cell lymphoma than either drug alone.

OUTLINE:

Patients receive standard of care lymphodepletion therapy consisting of cyclophosphamide and fludarabine on days -5 to -3 followed by liso-cel CAR-T cell infusion on day 0. Patients then receive NKTR-255 intravenously (IV) over 30 minutes every 3 weeks starting on day 10 or 14 in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 30 days for 3 months, then every 3 months up to 12 months after the CAR-T cell infusion.

Exclusion Criteria:

Known human immunodeficiency virus (HIV) infection
Pregnant or breastfeeding women
Prior treatment with any IL-2 or IL-15 agonist and/or biosimilar agents

Active autoimmune or inflammatory disorders (including inflammatory bowel disease [e.g., ulcerative colitis, Crohn's disease], celiac disease, or other serious chronic gastrointestinal conditions associated with diarrhea, autoimmune vasculitis, systemic lupus erythematosus, Wegener syndrome [granulomatosis with polyangiitis], myasthenia gravis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc.) within 1 year prior to the planned start of treatment. The following are exceptions to this criterion:

History of other clinically significant cardiac disease that, in the opinion of the PI or designee, is a contraindication to study treatment is also excluded
