First-in-Human CLL1-CD33 Compound CAR T Cell Therapy Induces Complete Remission in Patients with Refractory Acute Myeloid Leukemia: Update on Phase 1 Clinical Trial

ConclusionOur first-in-human clinical trial demonstrates promising efficacy of cCAR therapy in treating patients with relapsed/ refractory AML. cCAR is able to eradicate leukemia blasts and leukemia stem cells, exerting a profound tumor killing effect that is superior to single target CAR T cell therapies. cCAR is also shown to induce total myeloid ablation in bone marrow, suggesting that it may act as a safer alternative to avoid the severe toxicities caused by standard bone marrow ablation regimens without sacrificing the anti-tumor efficacy. This strategy will likely benefit patients who are unable to tolerate total body radiation or high dose chemotherapies. In addition to AML, cCAR also has the potential to treat blast crisis developed from myelodysplastic syndrome, chronic myeloid leukemia, and chronic myeloproliferative neoplasm.DisclosuresPinz: iCell Gene Therapeutics LLC: Employment.

This paradoxical effect of chemotherapy can affect different districts such as the primary tumor, the circulation and distant organs by s...

Through advances in DNA typing, more than 800 subtypes of HLA-A2 have been identified, and the existence of heterogeneity of antigen specificity among the HLA-A2 subtypes has been suggested by retrospective analyses of allogeneic transplantation patients and by studies of antigen amino acid structure. However, prior to this study, the antigenicity of a given subtype or the mismatch extent between two giv...

Antidepressant drugs that are currently prescribed do not benefit 30% of treated individuals. Furthermore, there is a delay of 3 or more weeks before a reduction in symptoms. Results from preclinical studies have indicated an important role for trophic factors in regulating behavior. Erythropoiet...
