Abstract (sommario):

Recent advances in the field of nanotechnology application in nuclear medicine offer the promise of better therapeutic options. In recent years, increasing efforts have been made on developing nanoconstructs that can be used as carriers for immobilising alpha (α)-emitters in targeted drug delivery. In this publication, we provide a comprehensive overview of available information on functional nanomaterials for targeted alpha therapy. The first section describes why nanoconstructs are used for the synthesis of α-emitting radiopharmaceuticals. Next, we present the synthesis and summarise the recent studies demonstrating therapeutic applications of α-emitting labelled radiobioconjugates in targeted therapy. Finally, future prospects and the emerging possibility of therapeutic application of radiolabelled nanomaterials are discussed.

Abstract (sommario):

Targeted alpha therapy (TAT) has the advantage of delivering therapeutic doses to individual cancer cells while reducing the dose to normal tissues. TAT applications relate to hematologic malignancies and now extend to solid tumors. Results from several clinical trials have shown efficacy with limited toxicity. However, the dosimetry for the labeled alpha particle is challenging because of the heterogeneous antigen expression among cancer cells and the nature of short-range, high-LET alpha radiation. This paper demonstrates that it is inappropriate to investigate the therapeutic efficacy of TAT by macrodosimetry. The objective of this work is to review the microdosimetry of TAT as a function of the cell geometry, source-target configuration, cell sensitivity, and biological factors. A detailed knowledge of each of these parameters is required for accurate microdosimetric calculations.

Abstract (sommario):

Tumor necrosis factor-alpha (TNF-α), a member of the TNF superfamily, was the first cytokine to be evaluated for cancer biotherapy. However, the clinical use of TNF-α is severely limited by its toxicity. Currently, TNF-α is administered only through locoregional drug delivery systems such as isolated limb perfusion and isolated hepatic perfusion. To reduce the systemic toxicity of TNF-α, various strategies have been explored over the last several decades. This review summarizes current state-of-the-art targeted cancer therapy using TNF-α. Passive targeting, cell-based therapy, gene therapy with inducible or tissue-specific promoters, targeted polymer-DNA complexes, tumor pre-targeting, antibody-TNF-α conjugate, scFv/TNF-α fusion proteins, and peptide/TNF-α fusion proteins have all been investigated to combat cancer. Many of these agents are already in advanced clinical trials. Molecular imaging, which can significantly speed up the drug development process, and nanomedicine, which can integrate both imaging and therapeutic components, has the potential to revolutionize future cancer patient management. Cooperative efforts from scientists within multiple disciplines, as well as close partnerships among many organizations/entities, are needed to quickly translate novel TNF-α-based therapeutics into clinical investigation.

Abstract (sommario):

There is a lack of data related to activity uptake and particle track distribution in targeted alpha therapy. These data are required to estimate the absorbed dose on a cellular level as alpha particles have a limited range and traverse only a few cells. Tracking of individual alpha particles is possible using the Timepix semiconductor radiation detector. We investigated the feasibility of imaging alpha particle emissions in tumour sections from mice treated with Thorium-227 (using APOMAB), with and without prior chemotherapy and Timepix detector. Additionally, the sensitivity of the Timepix detector to monitor variations in tumour uptake based on the necrotic tissue volume was also studied. Compartmental analysis model was used, based on the obtained imaging data, to assess the Th-227 uptake. Results show that alpha particle, photon, electron, and muon tracks were detected and resolved by Timepix detector. The current study demonstrated that individual alpha particle emissions, resulting from targeted alpha therapy, can be visualised and quantified using Timepix detector. Furthermore, the variations in the uptake based on the tumour necrotic volume have been observed with four times higher uptake for tumours pretreated with chemotherapy than for those without chemotherapy.

Abstract (sommario):

The fundamental principles of internal targeted alpha therapy for cancer were established many decades ago. The high linear energy transfer (LET) of alpha radiation to the targeted cancer cells causes double strand breaks in DNA. At the same time, the short range of alpha- radiation spares adjacent normal tissues. This targeted approach complements conventional external beam radiotherapy and chemotherapy. Such therapies fail on several fronts, such as lack of control of some primary cancers (eg glioblastoma multiforme) and inhibition of the development of lethal metastatic cancer after successful treatment of the primary cancer. This review charts the developing role of systemic high LET in internal radiation therapy. Targeted alpha therapy is a rapidly advancing experimental therapy that holds promise to deliver high cytotoxicity to targeted cancer cells. Initially thought to be indicated for leukaemia and micrometastases, there is now evidence that solid tumours can also be regressed. Alpha therapy may be molecular or physiological in its targeting. Alpha emitting radioisotopes such as Bi-212, Bi-213, At-211 and Ac-225 are used to label monoclonal antibodies or proteins that target specific cancer cells. Alternatively, radium-233 is used for palliative therapy of breast and prostate cancers because of its bone seeking properties. In this review, preclinical studies and clinical trials of alpha therapy are discussed for leukaemia, lymphoma, melanoma, glioblastoma multiforme, bone metastases, ovarian cancer, pancreatic cancer and other cancers.

Abstract (sommario):

Over the last decade, targeted alpha therapy has demonstrated its high effectiveness in treating various oncological diseases. Lead-212, with a convenient half-life of 10.64 h, and daughter alpha-emitter short-lived 212Bi (T1/2 = 1 h), provides the possibility for the synthesis and purification of complex radiopharmaceuticals with minimum loss of radioactivity during preparation. As a benefit for clinical implementation, it can be milked from a radionuclide generator in different ways. The main approaches applied for these purposes are considered and described in this review, including chromatographic, solution, and other techniques to isolate 212Pb from its parent radionuclide. Furthermore, molecules used for lead’s binding and radiochemical features of preparation and stability of compounds labeled with 212Pb are discussed. The results of preclinical studies with an estimation of therapeutic and tolerant doses as well as recently initiated clinical trials of targeted radiopharmaceuticals are presented.

Abstract (sommario):

Systemic or locoregionally administered alpha-particle emitters are highly potent therapeutic agents used in oncology that are fundamentally novel in their mechanism and, most likely, overcome radiation resistance as the alpha particles emitted have a short range and a high linear energy transfer. The use of alpha emitters in a clinic environment requires extra measures with respect to imaging, dosimetry, and radiation protection. This is shown for the example of 223Ra dichloride therapy. After intravenous injection, 223Ra leaves the blood and is taken up rapidly in bone and bone metastases; it is mainly excreted via the intestinal tract. 223Ra can be imaged in patients with a gamma camera. Dosimetry shows that, after a series of six treatments for a 70-kg person with an overall administered activity of 23 MBq, 223Ra results in an absorbed alpha dose of approximately 17 Gy to the bone endosteum and approximately 1.7 Gy to the red bone marrow. During administration, special care must be taken to ensure that no spill is present on the skin of either the patient or staff. Due to the low dose rate, the treatment is normally performed on an outpatient basis; the patient and carers should receive written instructions about the therapy and radiation protection.

Abstract (sommario):

Targeted alpha-particle therapy (TAT) aims to selectively deliver radionuclides emitting α-particles (cytotoxic payload) to tumors by chelation to monoclonal antibodies, peptides or small molecules that recognize tumor-associated antigens or cell-surface receptors. Because of the high linear energy transfer (LET) and short range of alpha (α) particles in tissue, cancer cells can be significantly damaged while causing minimal toxicity to surrounding healthy cells. Recent clinical studies have demonstrated the remarkable efficacy of TAT in the treatment of metastatic, castration-resistant prostate cancer. In this comprehensive review, we discuss the current consensus regarding the properties of the α-particle-emitting radionuclides that are potentially relevant for use in the clinic; the TAT-mediated mechanisms responsible for cell death; the different classes of targeting moieties and radiometal chelators available for TAT development; current approaches to calculating radiation dosimetry for TATs; and lead optimization via medicinal chemistry to improve the TAT radiopharmaceutical properties. We have also summarized the use of TATs in pre-clinical and clinical studies to date.

Abstract (sommario):

Glypican-3 (GPC3) is expressed in 75% of hepatocellular carcinoma (HCC), but not normal liver, making it a promising HCC therapeutic target. GC33 is a full-length humanized monoclonal IgG1 specific to GPC3 that can localize to HCC in vivo. GC33 alone failed to demonstrate therapeutic efficacy when evaluated in patients with HCC; however, we posit that cytotoxic functionalization of the antibody with therapeutic radionuclides, may be warranted. Alpha particles, which are emitted by radioisotopes such as Actinium-225 (Ac-225) exhibit high linear energy transfer and short pathlength that, when targeted to tumors, can effectively kill cancer and limit bystander cytotoxicity. Macropa, an 18-member heterocyclic crown ether, can stably chelate Ac-225 at room temperature. Here, we synthesized and evaluated the efficacy of [225Ac]Ac–Macropa–GC33 in mice engrafted with the GPC3-expressing human liver cancer cell line HepG2. Following a pilot dose-finding study, mice (n = 10 per group) were treated with (1) PBS, (2) mass-equivalent unmodified GC33, (3) 18.5 kBq [225Ac]Ac–Macropa–IgG1 (isotype control), (4) 9.25 kBq [225Ac]Ac–Macropa–GC33, and (5) 18.5 kBq [225Ac]Ac–Macropa–GC33. While significant toxicity was observed in all groups receiving radioconjugates, the 9.25 kBq [225Ac]Ac–Macropa–GC33 group demonstrated a modest survival advantage compared to PBS (p = 0.0012) and 18.5 kBq [225Ac]Ac–IgG1 (p = 0.0412). Hematological analysis demonstrated a marked, rapid reduction in white blood cells in all radioconjugate-treated groups compared to the PBS and unmodified GC33 control groups. Our studies highlight a significant disadvantage of using directly-labeled biomolecules with long blood circulation times for TAT. Strategies to mitigate such treatment toxicity include dose fractionation, pretargeting, and using smaller targeting ligands.

Abstract (sommario):

Introduction: Targeted alpha therapy (TAT) is a new experimental therapy that targets cancer cells and tumor capillary endothelial cells through intravenous injection of an alpha immuneconjugate (AIC). The AIC is formed by labeling the cancer targeting vector (monoclonal antibody) with alpha emitting radioisotopes using a bifunctionalchelator. The monoclonal antibody (MAb) is raised against antigens (e.g. MUC1) over-expressed on the surface of certain cancer cells. There are several centers notably in Europe, the US and Australia that are actively involved in TAT clinical trials of different cancers using a variety of techniques, alpha emitters and MAbs. Observations from their cumulative experience suggest that TAT is safe and effectivebut needs further trials for practical acceptance. Especially critical is the issue of maximum tolerance dose (MTD) which needs to be established for maximum target kill. Bangladesh has the infrastructure to conduct aTAT clinical trial and can significantly add to the growing pool of data for advanced treatment of cancers through collaborative involvement in targeted alpha therapy research.Objective: The aim of the article is to present a general overview of targeted alpha therapy and to discuss the feasibility of a TAT clinical trial in Bangladesh in the context of current cancer management situation in the country.Method: Literature review of significant publications was done to obtain an update of the current status of targeted alpha therapy. Relevant issues of TAT are presented for a theoretical basis of the technology. Next, the methodology of a proposed clinical trial is discussed, together with the practicability of its introduction in Bangladesh.Conclusion: Implementation of TAT clinical trial will help to develop an advanced technology and build- up skilled manpower in Bangladesh.It will optimize the key parameters of targeted alpha therapy, i e stability and specific activity of the alpha-conjugate and establish the maximum tolerance dose for the AIC. If the clinical trial is successful, it can change the prognosis of many end-stage cancers. Patients in Bangladesh with advanced MUCI expressing tumors of the breast, ovary, pancreas and prostate can have some measure of hope with stability of the disease.Bangladesh J.

Abstract (sommario):

Several radiometals are of interest in the development of new α-emitting radiopharmaceuticals. This review highlights the role of coordination chemistry in the design of 225Ac, 212/213Bi, 212Pb, 149Tb, 227Th, and 223/224Ra radiopharmaceuticals to treat cancer. Several chelators have recently been developed that are addressing the specific requirements of each radiometal to provide outstanding radiolabelling and in vivo properties. These advances are supporting the momentum that is building around radiopharmaceuticals for targeted α therapy.

Abstract (sommario):

Abstract Background Brain metastases (BM) develop frequently in patients with breast cancer. Despite the use of external beam radiotherapy (EBRT), the average overall survival is short (6 months from diagnosis). The therapeutic challenge is to deliver molecularly targeted therapy at an early stage when relatively few metastatic tumor cells have invaded the brain. Vascular cell adhesion molecule 1 (VCAM-1), overexpressed by nearby endothelial cells during the early stages of BM development, is a promising target. The aim of this study was to investigate the therapeutic value of targeted alpha-particle radiotherapy, combining lead-212 (212Pb) with an anti–VCAM-1 antibody (212Pb-αVCAM-1). Methods Human breast carcinoma cells that metastasize to the brain, MDA-231-Br-GFP, were injected into the left cardiac ventricle of nude mice. Twenty-one days after injection, 212Pb-αVCAM-1 uptake in early BM was determined in a biodistribution study and systemic/brain toxicity was evaluated. Therapeutic efficacy was assessed using MR imaging and histology. Overall survival after 212Pb-αVCAM-1 treatment was compared with that observed after standard EBRT. Results 212Pb-αVCAM-1 was taken up into early BM with a tumor/healthy brain dose deposition ratio of 6 (5.52e108 and 0.92e108) disintegrations per gram of BM and healthy tissue, respectively. MRI analyses showed a statistically significant reduction in metastatic burden after 212Pb-αVCAM-1 treatment compared with EBRT (P < 0.001), translating to an increase in overall survival of 29% at 40 days post prescription (P < 0.01). No major toxicity was observed. Conclusions The present investigation demonstrates that 212Pb-αVCAM-1 specifically accumulates at sites of early BM causing tumor growth inhibition.
