SUPPLEMENTARY INFORMATION: The BER Medical Applications Program supports directed nuclear medicine technology research in the areas of radiopharmaceutical development, molecular nuclear medicine and advanced biomedical imaging to promote the use of radioisotopes for non-invasive diagnosis and therapy.

The early BER programs focused on understanding the physical, chemical and biologic consequences of radionuclide decay in the human body. Those studies led to much of the basic information that is still used today to describe the therapeutic effects of targeted radionuclides. DOE continued to fund projects and develop technologies for therapeutic effect and use of radiation that generated much of the current knowledge in radioisotope chemistry, identification of targeting agents, methods for chemical coupling of isotopes to targeting agents, scanning and imaging techniques, mathematical modeling and internal radiation dosimetry. This research has formed the basis for many current cancer targeted radionuclide therapy modalities in various stages of development.

Current themes have developed about radiation's main molecular targets, absorbed energy doses and resultant radiation damage. This has led to the development of defined absorbed doses (Gy, Sv) that dominate our predictions about tumor destruction and normal tissue damage. Most radiobiology has been focused on radiation damage induced by high dose rate gamma and neutron exposures. Targeting with electrons, alpha and beta emitters employed at intermediate to low dose rate intensities requires a much better understanding of radiation damage to cells, and new paradigms need to be addressed to understand how best to use radioisotopes for selective destruction of solid tumors as compared to normal tissue. The recent emphasis on targeted radiopharmaceutical therapy agents against many forms of cancer has brought about an increase in the need for reliable and clinically meaningful, patient-specific internal dose calculations. The ability to link radiation dose to observed biological effect of radiation is complicated by a number of factors, including the heterogeneity of the activity distribution within normal organ tissue or within tumors, the range of the particles delivering the therapeutic dose, the total dose received, the dose rate at which the dose is delivered, (which depends on the radionuclide half- life), and the radiosensitivity of the tumor cells.

Basic research in molecular biology has provided new insights to the molecular basis of human disease and its potential molecular targets. DOE’s current Molecular Nuclear Medicine Program encourages development of new technologies for molecular delivery of radioisotopes to disease target sites with a high degree of precision, recognition, and target selectivity. The availability of new technology for high resolution imaging of small animals should facilitate the evaluation of the biological effects of ionizing radiation.

This Announcement is to solicit proposals for developing innovative technologies for in vivo targeted radiopharmaceutical dose delivery and improved radiotoxic dose deposition in the target as compared to normal tissue. A well integrated team effort by scientists from overlapping disciplines of radiochemistry, radiopharmaceutical chemistry, cellular and molecular radiobiology, radiation oncology, targeted radiation therapy, microdosimetry and modeling will be important. Methodological approaches and sensitive technologies that can be adapted to deliver, deposit, measure and predict therapeutic levels of radiation dose to the target sites are sought. It will be important for each proposal to address also the following objectives:

1. Radiolabeling of targeting molecules at therapeutic dose levels of radioactivity.

2. Considerations of radiochemical and in vivo biological viability (activity, stability, target specificity, and selectivity) of the molecule, against sensitivity to structural perturbations in the molecule as a result of radiolabeling.

3. Radiopharmaceutical delivery of intact radioisotopically labeled molecules to tumor cells in therapeutic dose amounts.

4. Innovative measurement techniques for evaluating biological effects of therapeutic radiation at low dose rates in vivo at the molecular, cellular and metabolic levels.

5. Modeling and microdosimetry methods for understanding the biological effects of radiation at the cellular and subcellular level for guiding predictions about optimum radiation dose, radiation dose rate, and resultant tumor destruction and normal tissue damage.

6. Measurement techniques for accurately assessing the success of tumor targeting in vivo.

7. The research plan will support BER Medical Applications long term performance goals in scientific advancement by providing innovative radiopharmaceutical methodologies or technologies for use in solid tumor cell destruction. Applicants should note that only a methodology or a technology offering promise for intended use, and not the experimental data resulting from the proposed research will be considered an accomplishment and will contribute to the measures of performance.

Program Funding

It is anticipated that up to $2 million will be available for multiple awards starting Fiscal Year 2004 to Fiscal Year 2005, contingent upon the availability of appropriated funds and the scientific merit of the submitted proposals.
