AlloNK ® Cell Therapy ± Rituximab in Patients with Relapsed or Refractory Non‑Hodgkin Lymphoma (ASGCT 2025) - P1/2 | "AlloNK cell therapy is a safe and effective cellular therapy for B cell lymphomas. Given its alternative mechanism of action, AlloNK has the potential to enhance the ADCC response, thereby increasing anti-tumor activity without the safety challenges associated with T cell approaches, including high rates of CRS and ICANS. The combination of AlloNK and rituximab has demonstrated promising safety and efficacy in a heavily pretreated R/R NHL patient population, including older patients."

AlloNK: A Scalable and Consistent NK Cell Therapy in Development for Treatment of Oncology and Autoimmune Diseases (ASGCT 2025) - "Initial clinical data with rituximab and AlloNK in subjects with advanced B-cell malignancies showed that this treatment approach is well tolerated, and preliminary efficacy of the combination treatment is encouraging (Khanal R 2023). The current scale of AlloNK production from CBU to DP equates to ≥ 4, 000 net vials of 1 billion NK cells per CBU, which is enough to potentially treat >1, 000 patients (assuming administration of 3 billion cells per patient). The drug product generated is uniformly high in CD16 expression and has consistent potency across lots. The current scale can support both clinical trial demand as well as potential commercial launch."
