Presenting Key Opinion Leaders:

Dr. Carlos Ramos is currently an Associate Professor of Medicine in the Center for Cell and Gene Therapy at the Baylor College of Medicine, and an Attending Physician in the Blood and Marrow Transplantation Service at the Houston Methodist Hospital. As a faculty member, he has focused his research efforts on T-cell therapy for malignancies and viral infections. He has broad experience in cellular therapy for hematologic cancers, being the principal investigator in trials using chimeric antigen receptor (CAR)-modified T cells targeting CD19, CD30 and kappa light chain as therapy for non-Hodgkin and Hodgkin lymphoma and multiple myeloma. He is also implementing cellular therapy approaches for patients with Human Papilloma Virus (HPV)-associated malignancies, using HPV-specific T cells. Dr. Ramos earned his Medical Degree with Honors from the University of Lisbon, Portugal, and was a Resident in Internal Medicine at the Baylor College of Medicine, in Houston. He completed Fellowships in Hematology and Medical Oncology at the Memorial Sloan-Kettering Cancer Center, in New York, and in Blood and Marrow Transplantation at the University of Texas M. D. Anderson Cancer Center, in Houston.

Dr. Leonid Metelitsa is involved in research focused on understanding the role of Vα24-invariant natural killer T cells (iNKTs) in tumor immunity. Using clinical samples from neuroblastoma patients, his lab demonstrated for the first time that iNKTs localize to primary tumors and their presence at the tumor site is associated with good outcome. In the pursuit of the underlying mechanistic basis for the observed association between iNKTs and clinical outcome, Dr. Metelitsa’s group has published a series of high-impact papers that revealed the mechanisms of iNKT cell tumor localization and function in the tumor microenvironment. In one of these studies, they discovered the mechanism by which iNKTs attack tumor-associated macrophages (TAMs). That study has had a major impact in the fields of NKT cell and neuroblastoma research. First, it explained how iNKTs can mediate antitumor activity against CD1d-negative tumors, the majority of solid tumors in humans. Second, it showed for the first time that macrophages infiltrate primary tumors in a subset of neuroblastoma patients, their products directly support tumor growth, and their presence at the tumor site is associated with poor clinical outcome. This discovery has been validated in large international study validated using large independent cohorts of patients, concluding that the presence of M2-like macrophages is associated with a novel inflammatory signature in neuroblastoma that serves as an independent prognostic factor of extremely poor outcome. Most recently, Dr. Metelitsa has been focused on the development of therapeutic applications using iNKTs and their synthetic ligands.

Dr. Sattva Neelapu is professor and deputy chair of Lymphoma and Myeloma at The University of Texas MD Anderson Cancer Center in Houston, Texas. As a physician-scientist at MD Anderson, Dr. Neelapu is focused on clinical and translational development of novel immunotherapies for B-cell malignancies. His laboratory characterized some of the major immunosuppressive mechanisms in the tumor microenvironment of B-cell malignancies, identified TCL1 as a novel shared tumor-associated antigen for B-cell lymphomas, and investigated novel targets for CAR T-cell therapy in lymphoma and myeloma. His work on the pivotal trial of axicabtagene ciloleucel CD19 CAR T-cell therapy in aggressive B-cell lymphomas led to its FDA approval as the first CAR T therapy for lymphoma. Dr. Neelapu has authored or co-authored over 150 publications.

About the Phase I Study of KUR-502 (Allogeneic CD19 CAR-NKT Cells) in Patients with Relapsed or Refractory B-Cell Malignancies (ANCHOR)

The phase I study is an open-label, dose-escalation study. NKT cells were isolated from the leukapheresis product of one HLA-unmatched healthy individual, transduced with the CAR, expanded ex vivo for 14 days (99.8% NKT purity), and cryopreserved. Patients received 10⁷ (DL 1) or 3×10⁷ (DL 2) CAR-NKT cells per square meter of body surface area following lymphodepleting conditioning with cyclophosphamide/fludarabine. Adverse events were evaluated per NCI criteria. When accessible, patients underwent core biopsies of an involved site at 2-5 weeks post-infusion. Response to therapy was assessed at 4 weeks per Lugano Criteria (for NHL) or NCCN guidelines (for ALL).
