UNLABELLED Physiologic barriers to the delivery of macromolecules to solid tumors are a major obstacle to the clinical success of radioimmunotherapy (RIT). Only a small fraction of the injected dose of the radiolabeled monoclonal antibody (mAb) localizes at the tumor site. This situation worsens as the tumor burden increases. It is hypothesized that improvements to RIT of adenocarcinoma can be ...
Radioimmunotherapy (RIT) of Non-Hodgkin’s lymphoma (NHL) is said to be more advantageous compared to unlabelled therapeutic antibodies. To this date, radiolabelled murine anti-CD20 mAbs, Zevalin® and Bexxar® have been approved for imaging and therapy. A preparation containing rituximab, chimeric mAb radioimmunoconjugate suitable for Lu-177 labeling, could provide better imaging and therapeutic ...
OBJECTIVE Radioimmunotherapy (RIT) has proven effective for patients with relapsed and refractory lymphoma. However, new types of therapy are strongly desired as B-cell lymphoma remains incurable for many patients. Photoimmunotherapy (PIT) is an emerging targeted cancer therapy that uses photosensitizer (IR700)-conjugated monoclonal antibodies (mAbs) to specifically kill cancer cells. To evalua...
Eliminating virally infected cells is an essential component of any HIV eradication strategy. Radioimmunotherapy (RIT), a clinically established method for killing cells using radiolabeled antibodies, was recently applied to target HIV-1 gp41 antigen expressed on the surface of infected cells. Since gp41 expression by infected cells is likely downregulated in patients on antiretroviral therapy ...
As small cell lung carcinoma (SCLC) is frequently a widespread disease at diagnosis, highly radiosensitive and often only partially responsive to chemotherapy, radioimmunotherapy (RIT) would appear to be a promising technique for treatment. We report the preliminary results of a Phase I/II trial of RIT in SCLC using a two-step method and a myeloablative protocol with circulating stem cells tran...
PURPOSE To evaluate the feasibility of radioimmunotherapy (RIT) with radiolabeled anti-carcinoembryonic antigen antibodies after complete resection of liver metastases (LM) from colorectal cancer. PATIENTS AND METHODS Twenty-two patients planned for surgery of one to four LM received a preoperative diagnostic dose of a 131I-F(ab')2-labeled anti-carcinoembryonic antigen monoclonal antibody F6 ...
introduction: radioimmunotherapy (rit) is a very promising new therapy for the treatment of recurrent b-cell non-hodgkin's lymphoma (nhl). iodine-131 is the most frequently used nuclide in clinical rit, but its usefulness has been limited by dehalogenation of monoclonal antibodies labeled via conventional methods. to circumvent this problem, we have synthesized a tri-peptide consisting of non-m...
Abstract Background Radio-immunotherapy (RIT) with Lu- 177 labeled 6A10-Fab fragments, targeting tumor-associated carbonic anhydrase XII (CA12) and applied directly into the resection cavity, offers a promising strategy to address hibernating tumor burden after completion of adjuvant treatment for glioblastoma. We report on first in human applications. METHODS Three patients underwent microsurg...
The purpose of this study was 2-fold: to determine the maximum tolerated dose (MTD) of 64Cu-bromoacetamidobenzyl-l,4,8,11-tetraazacyclotetradecane-N,N',N",N"-tetraacetic acid (BAT)-2-iminothiolane (2IT)-monoclonal antibody (MAb) 1A3 in hamsters, and second, to determine the therapeutic efficacy of 64Cu-BAT-2IT-MAb 1A3 at various dose levels in hamsters with large (600 mg), 7-day-old GW39 human ...
BACKGROUND Head and neck squamous cell carcinoma (HNSCC) is the sixth most common malignancy worldwide with a poor prognosis. Human papilloma virus (HPV) infection is associated with 20% HNSCC, and 50% of oropharyngeal carcinoma. HPV16 type is detected in 90% of all HPV+ HNSCC. Recently we suggested a fundamentally different approach to treatment of cancers of viral origin by targeting viral an...
