This review describes the current status of targeted radiotherapy, an alternative strategy for brain tumour treatment that offers the exciting prospect of increasing the specificity of tumour cell irradiation.

This article summarizes the current trials available in the NIH database, the largest trial repository, to provide both an overview of the current landscape and a glimpse towards an undeniably exciting future of theranostics. This landscape analysis was completed by searching the terms “radionuclide therapy”, “radioisotope therapy”, “radiopharmaceutical therapy” and “radioligand therapy” on ClinicalTrials.gov in November 2020. Other terms may provide different results. Phase 1/2, 2, and 3 trials that are currently recruiting and those not yet recruiting were included. Studies. Overall, the results showed 42 clinical trials including 13 Phase 1/2, 26 Phase 2, and three Phase 3. Given this range of phases, the planned enrollment varies widely from 10-813, with an average of 147 participants. Five different radioisotopes, 12 ligands or targets, and 11 different cancer types are represented (Figure 1). -
Radioisotopes and Radiopharmaceuticals
RADIOISOTOPES AND RADIOPHARMACEUTICALS Radioisotopes are the unstable form of an element that emits radiation to become a more stable form — they have certain special attributes. These make radioisotopes useful in areas such as medicine, where they are used to develop radiopharmaceuticals, as well as many other industrial applications.

They are used in various fields, including nuclear medicine, where radiopharmaceuticals play a major role. Radiopharmaceuticals are substances that contain a radioisotope, and have properties that make them effective markers in medical diagnostic or therapeutic procedures. The chemical presence of radiopharmaceuticals can relay detailed information to medical professionals that can help in diagnoses and treatments. Eighty percent of all diagnostic medical scans worldwide use 99mTc, and its availability, at present, is dependent on the production of 99Mo in research reactors. Globally, the number of medical procedures involving the use of radioisotopes is growing, with an increasing emphasis on radionuclide therapy using radiopharmaceuticals for the treatment of cancer.. -

INTRODUCTION The United States Nuclear Regulatory Commission had requested information to support MDS Nordion application for the registration of TheraSphere. This request is contained in a letter dated November 23, 1999 from a Dr John P. Jankovich. This report contains data collected to address question 7 parts a, b, and c. The question poised is as follows: "Regarding external radiation levels, NRC needs information on the device itself, not on the radiation levels around the patient as addressed in the application. Therefore, please specify: a. External radiation levels around the lucite vial containing the maximum dose of 20 GBq (540 mCi). Provide the data, preferably, at the surface, and at 5, 30, and 100 cm. If there are no meaningful readings at these locations, please state so. b. Provide similar external radiation levels, if any, outside the lead pot with the lucite vial inside containing a maximum dose of microspheres. c. Please specify the instrument which you used to perform the radiation profile measurements by listing the instrument manufacturers, model numbers, calibration dates, sensitivity, etc." To address these questions, information was provided from previous development work. -

Targeted Radiotherapeutics from 'Bench-To-Bedside'
RadiochemistRy in switzeRland CHIMIA 2020, 74, No. 12 939 doi:10.2533/chimia.2020.939 Chimia 74 (2020) 939–945 © C. Müller, M. Béhé, S. Geistlich, N. P. van der Meulen, R. Schibli Targeted Radiotherapeutics from ‘Bench-to-Bedside’ Cristina Müllera, Martin Béhéa, Susanne Geistlicha, Nicholas P. van der Meulenab, and Roger Schibli*ac Abstract: The concept of targeted radionuclide therapy (TRT) is the accurate and efficient delivery of radiation to disseminated cancer lesions while minimizing damage to healthy tissue and organs. Critical aspects for success- ful development of novel radiopharmaceuticals for TRT are: i) the identification and characterization of suitable targets expressed on cancer cells; ii) the selection of chemical or biological molecules which exhibit high affin- ity and selectivity for the cancer cell-associated target; iii) the selection of a radionuclide with decay properties that suit the properties of the targeting molecule and the clinical purpose. The Center for Radiopharmaceutical Sciences (CRS) at the Paul Scherrer Institute in Switzerland is privileged to be situated close to unique infrastruc- ture for radionuclide production (high energy accelerators and a neutron source) and access to C/B-type labora- tories including preclinical, nuclear imaging equipment and Swissmedic-certified laboratories for the preparation of drug samples for human use. These favorable circumstances allow production of non-standard radionuclides, exploring their biochemical and pharmacological features and effects for tumor therapy and diagnosis, while investigating and characterizing new targeting structures and optimizing these aspects for translational research on radiopharmaceuticals. In close collaboration with various clinical partners in Switzerland, the most promising candidates are translated to clinics for ‘first-in-human’ studies. -

The aim of this study was to assess the current practice of MRT and dosimetry across European countries. Methods: An electronic questionnaire was distributed to European countries. This addressed 18 explicitly considered therapies, and for each therapy, a similar set of questions were included. Questions covered the number of patients and treatments during 2015, involvement of medical specialties and medical physicists, implementation of absorbed dose planning, post-therapy imaging and dosimetry, and the basis of therapy prescription. Results: Responses were obtained from 26 countries and 208 hospitals, administering in total 42,853 treatments. The most common therapies were 131I-NaI for benign thyroid diseases and thyroid ablation of adults. The involvement of a medical physicist (mean over all 18 therapies) was reported to be either minority or never by 32% of the responders. -
Bispecific Antibody Pretargeting of Radionuclides for Immuno^ Single
Bispecific Antibody Pretargeting of Radionuclides for Immuno ^ Single-Photon Emission Computed Tomography and Immuno ^ Positron Emission Tomography Molecular Imaging:An Update Robert M. Sharkey,1Habibe Karacay,1William J. McBride,2 Edmund A. Rossi,3 Chien-Hsing Chang,3 and David M. Goldenberg1 Abstract Molecular imaging is intended to localize disease based on distinct molecular/functional characteristics. Much of today’s interest in molecular imaging is attributed to the increased acceptance and role of 18F-flurodeoxyglucose (18F-FDG) imaging in a variety of tumors. The clinical acceptance of 18F-FDG has stimulated research for other positron emission tomography (PET) agents with improved specificity to aid in tumor detection and assessment. In this regard, a number of highly specific antibodies have been described for different cancers. Although scintigraphic imaging with antibodies in the past was helpful in patient management, most antibody-based imaging products have not been able to compete successfully with the sensitivity afforded by 18F-FDG-PET, especially when used in combination with computed tomography. Recently, however, significant advances have been made in reengineering antibodies to improve their targeting properties. Herein, we describe progress being made in using a bispecific antibody pretargeting method for immuno ^ single-photon emission computed tomography and immunoPETapplications, as contrasted to directly radiolabeled antibodies.This approach not only significantly enhances tumor/nontumor ratios but also provides high signal intensity in the tumor, making it possible to visualize micrometastases of colonic cancer as small as 0.1to 0.2 mm in diameter using an anti ^ carcinoembryonic antigen bispecific antibody, whereas FDG failed to localize these lesions in a nude mouse model.
