Phase 2a Study of AlloNK Cord Blood-derived NK Cell Therapy Combined With Rituximab for Relapsing B-cell Rheumatologic Diseases Including RA, Sjgrens, Myopathies, and Systemic Sclerosis

What this Trial Is About

Researchers are evaluating the safety and effectiveness of AlloNK, a non-genetically modified allogeneic natural killer NK cell therapy derived from cord blood, combined with rituximab, in people with relapsing forms of B-cell dependent rheumatologic diseases. These diseases include refractory rheumatoid arthritis, Sjgrens disease, idiopathic inflammatory myopathies, and systemic sclerosis. This open-label Phase 2a study aims to explore treatment options for patients whose conditions have not responded well to previous therapies. Participants receive AlloNK after a conditioning regimen, followed by rituximab. AlloNK is an off-the-shelf, cryopreserved NK cell therapy given in combination with rituximab. The treatment period lasts up to 104 weeks, during which participants are monitored for safety and clinical response. The study includes one treatment group receiving this combination therapy. Throughout the study, participants undergo regular assessments to evaluate safety from enrollment until the end of treatment at Week 104. Researchers measure disease-specific outcomes at Week 52, including disease activity scores for rheumatoid arthritis, Sjgrens disease activity indices, improvement scores for inflammatory myopathies, and response indices for systemic sclerosis. The study involves clinical evaluations, laboratory tests including inflammatory markers, and joint assessments to monitor treatment effects and safety over the extended period.
