  Dosimetry  
 
Manuel Bardiès, PhD
Manuel Bardiès obtained his Doctorate on radiopharmaceutical dosimetry (with distinction) from Paul Sabatier University (Toulouse III) in November 15, 1991. He has been developing his research in radiopharmaceutical dosimetry within INSERM since 1991, in Nantes then in Toulouse.
Under his responsibility:
  - 10 PhD dissertations have been defended since 2000
  - 2 PhD projects are ongoing
  - 2 PhD projects are ongoing under the form of a co-supervision
  - Master training: about 30 Master student projects since 1995
  - Other training (Engineering students): about 20 students since 1996
  - Several academic or industrial projects have been funded and involved recruiting Post-Doctoral scientists.
  - Manuel Bardiès has authored or participated to more than 60 articles referenced in MedLine.
The team led by Manuel Bardiès in Toulouse is primarily involved in radiopharmaceutical dosimetry, at various scales (cell, tissue, organ). This requires the ability to assess radiopharmaceutical pharmacokinetics in vivo, through quantitative SPECT or PET small-animal imaging. An important part of research activity is related to Monte-Carlo modeling of radiation transport through biologic structures of interest, in order to give account of energy deposition within tumor targets – or conversely critical non-tumor tissues/organs. The objective is to improve molecular radiotherapy by allowing patient-specific treatments (personalized medicine).
 
       
  Pre-targeting strategies  
 
Sarah Cheal, PhD
Dr. Cheal's research focuses on the development of a theranostic platform approach for pretargeted radioimmunotherapy (PRIT) of solid human tumors. The lab at Memorial Sloan Kettering Cancer Center calls this strategy “DOTA-PRIT,” which is short for “DOTA ligand bound radionuclide-based pretargeted radioimmunotherapy.” In principle, DOTA-PRIT consists of three sequential administrations of three reagents: (i) the bi-specific Ab construct IgG-scFv (bsAb), which has high specificity and affinity for both a tumor antigen through the IgG and a radiolabeled hapten through the scFv; (ii) a clearing agent to eliminate unbound construct from the blood; and (iii) the imaging/therapeutic radioligand. The tumor targeting is separated from the payload-delivery step, thereby offering greater therapeutic indices (TIs) compared to conventional radioimmunodetection/radioimmunotherapy with directly labeled antibodies. Significant improvement in TIs permits high therapeutic doses of administered radioisotopes with minimal to no bystander side effects. In close collaboration with the lab of Nai-Kong Cheung at MSK and Dane Wittrup at MIT, they have successfully applied this platform in three preclinical tumor models: GPA33 antigen (colorectal cancer); GD2 antigen (neuroblastoma); and the HER2/neu receptor (breast cancer).

Dr. Hobbs' research focuses on dosimetry, which measures and calculates the radiation dose received by matter and tissue that has been exposed to radiation. His current studies examine various radiobiologic modeling techniques for treatment of specific tumors and cancers. Dr. Hobbs is also developing an alpha-particle dosimetry model that can examine alpha particles which are hard to study with current imaging modalities.
Dr. Hobbs is a member of the Radionuclide Therapy and Dosimetry (RTD) Research Lab, where he performs tail vein injections and bio-distribution, and provides assistance to Dr. Hong Song. He is engaged in research that examines how tumor burden and prior chemotherapy affects bone marrow dosimetry.

  Immune Effects  
 
Ravi Patel, MD, PhD
Dr. Patel is a Bentson Radiation Oncology Research Fellow in the Department of Human Oncology at the University of Wisconsin- Madison. He has an MD and PhD in biomedical engineering from Case Western University. He is pursuing a career as physician-scientist and one day hopes to have his own lab. He currently works in the Morris Lab, where he applies his expertise in mathematical modeling, drug delivery and in situ vaccination to a variety of research projects. One project looks at targeting metastatic disease through a combination of killing suppressive immune cells and using systemic immunotherapy agents. An exciting aspect about immunotherapy is that it could potentially work on a variety of cancers. Cancer has the ability to evade the immune system, so if we can figure out how to activate the immune system to recognize someone’s cancer, he thinks we can use those concepts on a wide variety of tumors.

Charles Kunos, MD, PhD, is a Medical Officer in the Investigational Drug Branch (IDB) of the Cancer Therapy Evaluation Program (CTEP), Division of Cancer Treatment and Diagnosis (DCTD) at the NCI and oversees adult and pediatric investigational therapeutics alone or in combination with radiation therapy. He received his medical and doctorate degrees from Case Western Reserve University School of Medicine in Cleveland, Ohio. He undertook radiation oncology training at the NCI-designated Case Comprehensive Cancer Center at University Hospitals of Cleveland. He then became the Clinical Director of the Gynecologic, Pediatric, and Musculoskeletal radiation therapy at University Hospitals of Cleveland. During his tenure, he developed skills in conventional radiotherapy, gynecologic brachytherapy, helical tomotherapy, gamma knife radiosurgery, and cyberknife stereotactic body radiosurgery. During this same time, he ran a radiobiology laboratory focused on the science of ribonucleotide reductase and its pharmacological inhibition by triapine using uterine cervix cancer preclinical models. He was the principal investigator for the NCI-sponsored phase I and II clinical trials of triapine radiochemotherapy for women with advanced stage uterine cervix cancer, which demonstrated very high overall response rates and progression-free survival. He was formerly the NCI Gynecologic Oncology Group’s liaison for Radiation Medicine, serving on multiple committees and task forces as well as serving as a Phase I co-chair of the Developmental Therapeutics Committee between 2012 and 2015.

Dr. Kunos joined NCI in 2016. He provides scientific review, develops and implements clinical trials, and monitors adverse events for a diverse drug portfolio involving experimental therapeutic agents that manipulate DNA damage responses by themselves or in combination with radiation therapy. He led NCI’s team that was granted Food & Drug Administration Orphan Drug Designation and Fast Track Designation for triapine in combination with cisplatin-radiation therapy for treatment of women with advanced stage uterine cervix cancer. He received a 2018 NCI Director’s Award for leading a team that improved uterine cervix cancer patient clinical trial access within Puerto Rico’s NCI Community Oncology Research Program (NCORP). He currently directs CTEP’s IDB Fellow and Early Career Investigator Externship Program and its educational efforts to improve written communication in CTEP’s Letters of Intent (LOIs).
