Clarity reported in a release that the first clinical site for the trial NCT04868604 opened at the.

64cu therapy. The half-life of 64 Cu is 127 h and it emits β 0653 MeV 178 and β 0579 MeV 384 electrons. This CRP reported the development of new small molecules and peptideantibody-based 64Cu-tracers for diagnostic imaging and therapy. The transmembrane cell adhesion receptor αVβ3 integrin αVβ3 has been identified as an important molecular target for cancer imaging and therapy.

Use of 64Cu-DOTA-Trastuzumab PET Imaging and Molecular Markers for Prediction of Response to Trastuzumab and Pertuzumab-Based Neoadjuvant Therapy. We have developed a tetrameric cyclic RGD Arg-Gly-Asp peptidebased radiotracer 64Cu-cyclam-RAFT-c-RGDfK-4 which successfully captured αVβ3-positive tumors and angiogenesis by PET. 64 Cu has a half-life of 127 hours and decays 179 by positron emission to 64 Ni 390 by beta decay to 64 Zn 431 by electron capture to 64 Ni and 0475 gamma radiationinternal conversionThese emissions are 0579 MeV 0653 MeV and 135 MeV for beta minus positron and gamma respectively.

Peptide receptor radionuclide therapy PRRT using radiolabeled octreotate is an effective treatment for somatostatin receptor 2expressing neuroendocrine tumors. Cu-diacetyl-bis N 4-methylthiosemicarbazone Cu-ATSM labeled with several Cu radioisotopes 60 Cu 62 Cu and 64 Cu is a potential PET imaging agent that targets tumor hypoxia with over-reduced. Hypoxia in tumors is known to contribute to the malignant characteristics such as therapy resistance and metastatic potential.

67Cu-SARTATE - In the dose escalation phase patients will receive a single administration of 67Cu-SARTATE as a slow IV infusion dose will be determined based on cohort allocation. MRI and PET data are collected prior to therapy and follow-up MRI scans are acquired at a midpoint in therapy. Quantitative data from magnetic resonance imaging MRI and 64Cu-DOTA-Trastuzumab positron emission tomography PET are used to estimate tumor density perfusion and distribution of HER2-targeted antibodies for each individual patient.

64Cu-diacetyl-bisN4-methylthiosemicarbazone 64Cu-ATSM is a promising radiotherapy agent for the treatment of hypoxic tumors. Methods CD20 expression was evaluated in lymphoma cell lines Jurkat and Raji. 2 Department of Chemical and.

Furthermore the shelf life of more than 24 h and the scanning window of at least 3 h make 64Cu-DOTATATE favorable and easy to use in the clinical setting. Actual Study Start Date. The significance of using 64 Cu-labeled cetuximab is that this probe can be simultaneously used for both imaging and therapy.

Authors Cristina Bolzati 1 Adriano Duatti 2 Affiliations 1 ICMATE-CNR Padua Italy. 64Cu-labeled radiopharmaceuticals such as 64Cu-PSMA and 64Cu-somatostatin analogs are promising imaging tools in the assessment of primary disease and also in the detection of disease recurrence and to evaluate therapy response. 64 Cu is considered to be suitable for both positron emission tomography PET and tumor radionuclide therapy.

The aim of the present study was in a larger prospective design to compare on a head-to-head basis the performance of 64Cu-DOTATATE and 111In. Enrollment has started for the phase 12 SECURE trial examining the novel PSMA theranostic 6467 Cu SAR-bisPSMA in patients with metastatic castration-resistant prostate cancer mCRPC according to Clarity Pharmaceuticals the company developing the treatment. 64Cu-SARTATE - patients will receive a bolus injection of 64Cu-SARTATE during screening and following each 67Cu-SARTATE Therapy Cycle at a rate of 20 MBqkg.

Epub 2020 Oct 7. Alternatively the sensitized 64 Cu-ATSM therapy could be used as an additional treatment along with chemotherapy or radiotherapy because based on the results of clinical Cu-ATSM PET studies and this study 64 Cu-ATSM can target regions within tumors that are resistant to other therapies. To date very few reports have described the clinical development of 64Cu as a radiotracer for cancer imaging.

DOTA-rituximab was conjugated and then chelated by 64Cu. Copper-64 64Cu is a cyclotron-produced radionuclide that has exhibited physical properties that are complementary for diagnosis andor therapeutic purposes. In addition it can be used to select patients for radioligand therapy and evaluate therapy response.

The main oxidation states of copper are I and II since Cu 3 is too. These findings suggest that integrated 64 Cu therapy can serve as a novel treatment strategy for peritoneal dissemination. Planned administration of chemotherapy anti-cancer cytokine therapy immunotherapy radiotherapy or other investigational agents within 2 weeks prior to the administration of 64Cu-SARTATE and 4 weeks prior to the administration of 67Cu-SARTATE.

Tumor xenograft models were established in BALBc. Neuroendocrine tumors NETs can be visualized using radiolabeled somatostatin analogs. 1516 It can be easily coordinated with numerous chelators and thus used for radiolabeling various peptides and other.

Objective The aim of this study was to evaluate the radiation dosimetry of alpha-emitter 225Ac-DOTA-rituximab using Monte Carlo simulation of 64Cu-DOTA-rituximab. To define the role of pre-therapy 64Cu-labeled diacetyl-bisN4-methylthiosemicarbazone copper Cu 64-ATSM in predicting prognosis and determining the behavior of an invasive squamous cell cervical cancer in patients with newly-diagnosed stage IB2-IVA cervical squamous cell carcinoma. 64 Cu is a radionuclide that uniquely emits positrons which are used for PET imaging and β particles and Auger electrons which are used for therapy 3 4.

The output from this CRP is a technological asset to the IAEA Member States. These new theranostic agents would be useful in the management of various types of cancers. The diagnostic and therapeutic potential of 64Cu and 67Cu respectively offers the possibility of using a single somatostatin receptortargeted peptide conjugate as a theranostic agent.

Actual Primary Completion Date. We have previously shown the clinical potential of 64Cu-DOTATATE in a small first-in-human feasibility study. 15 16 It can be easily coordinated with numerous chelators and thus used for radiolabeling various peptides and other biologically related small molecules monoclonal antibodies proteins and nanoparticles17 18 19 20.

64Cu is considered to be suitable for both positron emission tomography PET and tumor radionuclide therapy. Although patient-based sensitivity was the same for 64Cu-DOTATATE and 68Ga-DOTATOC in this cohort significantly more lesions were detected by 64Cu-DOTATATE. Estimated Study Completion Date.
