Researchers have used their approach for growing large numbers of NK cells to allow repeated dosing for a more effective and less toxic treatment.   Outcomes for patients with relapsed and refractory acute myeloid leukemia (R/R AML) have not significantly improved over the last 30 years. For example, a recent study of patients treated with…

A multi-faceted approach to precision medicine may allow clinicians to gain a better understanding of cancer and the complex ecosystem in which it resides. The field of precision medicine has evolved in leaps and bounds in the past two decades. Genomic profiling tools that were once cost-prohibitive and slow are now reasonably affordable and fast…

The third of three major challenges in enabling the clinical potential of NK cells for cancer therapy has just been addressed, thanks to the combined talents of gene editing experts and NK cell specialists at Nationwide Children’s Hospital.   Originally, NK cells seemed promising for a natural therapy to fight cancer due to their innate…

Optimizing the Body’s Natural Cancer Killers

Recent advances in the expansion and production of natural killer cells offers pediatric patients new hope for remission after high-risk cancer diagnoses. Natural killer (NK) cells are the innate immune system’s first line of defense for viral infections. Although these white blood cells don’t have the antigen-specific “memory” that characterizes T cells or the antibody-producing…

A case series of 13 patients with relapsed/refractory acute myeloid leukemia (AML) finds that a novel approach using repeated infusions of cultured natural killer (NK) cells increases overall and complete response rates. NK cells are lymphocytes – white blood cell components of the innate immune response – that have anti-leukemic properties. Although efforts to incorporate…

Administering NK Cells Post-Transplant Improves Relapse in Myeloid Malignancies

A Phase I/II clinical trial demonstrates donor-derived NK cells are safe and effective at decreasing relapse and increasing survival in adults with myeloid malignancies. Haploidentical stem-cell transplantation can be a successful treatment for patients with myeloid malignancies, but relapse remains a common risk. Natural killer (NK) cells are a subset of lymphocytes capable of recognizing…

A proof-of-concept study shows success in modifying NK cells for multiple myeloma. In a new proof-of-concept study, researchers from Nationwide Children’s Hospital used CRISPR/Cas9 technology to genetically modify natural killer immune cells, which they then showed are able to address a recognized hurdle in immunotherapy of multiple myeloma. “It was an amazing feeling when we…

Natural killer cells — critical for immune surveillance and host defense — have an important role in cancer immunotherapy and antiviral responses. While driving to the laboratory one day, Brian Tullius, MA, MD, a fourth-year bone marrow transplant and cell therapies fellow at Nationwide Children’s in the Lee Lab, had an epiphany. “I thought, ‘wait…

As COVID-19 spreads across the globe, experts are digging into the data and establishing protocols to better understand the illness in the context of pediatrics. As COVID-19, the illness caused by a novel coronavirus, has reached pandemic status, life has changed dramatically. At Nationwide Children’s Hospital, the halls are uncharacteristically quiet as a “stay at…

Clinician scientists collaborate to use virus-specific T-cells from the mother to successfully treat a systemic adenovirus infection in a preterm infant. It’s not every day that researchers can say that they’ve written and submitted and emergency investigational new drug (EIND) application to the Food & Drug Administration (FDA) and saved a life. But that’s what…
