Surgical Debulking Prior to Peptide Receptor Radionuclide Therapy (PRRT) in Patients With Well Differentiated Gastroenteropancreatic Neuroendocrine Tumors

This phase IV trial evaluates how well giving standard of care (SOC) peptide receptor radionuclide therapy (PRRT) after SOC surgical removal of as much tumor as possible (debulking surgery) works in treating patients with grade 1 or 2, somatostatin receptor (SSTR) positive, gastroenteropancreatic neuroendocrine tumors (GEP-NETs) that have spread from where they first started (primary site) to the liver (hepatic metastasis). Lutetium Lu 177 dotatate is a radioactive drug that uses targeted radiation to kill tumor cells. Lutetium Lu 177 dotatate includes a radioactive form (an isotope) of the element called lutetium. This radioactive isotope (Lu-177) is attached to a molecule called dotatate. On the surface of GEP-NET tumor cells, a receptor called a somatostatin receptor binds to dotatate. When this binding occurs, the lutetium Lu 177 dotatate drug then enters somatostatin receptor-positive tumor cells, and radiation emitted by Lu-177 helps kill the cells. Giving lutetium Lu 177 dotatate after surgical debulking may better treat patients with grade 1/2 GEP-NETs

The role of somatostatin receptor (SSTR) PET/CT, using ⁶⁸Ga-based tracers or [⁶⁴Cu]Cu-DOTATATE (⁶⁴Cu-DOTATATE), in the management of patients with neuroendocrine neoplasm (NEN) is guided by appropriate use criteria (AUC). In this study, we performed systematic analyses of referral patterns and image findings of routine ⁶⁴Cu-DOTATATE PET/CT scans to support AUC development. Methods: We included all clinical routine ⁶⁴Cu-DOTATATE PET/CT scans performed between April 10, 2018 (start of clinical use), and May 2, 2022, at Copenhagen University Hospital-Rigshospitalet. We reviewed the referral text and image report of each scan and classified the indication according to clinical scenarios as listed in the AUC. Results: In total, 1,290 patients underwent 2,249 ⁶⁴Cu-DOTATATE PET/CT scans. Monitoring of patients with NEN seen both on conventional imaging and on SSTR PET without clinical evidence of progression was the most common indication (defined as "may be appropriate" in the AUC) and accounted for 703 (31.3%) scans. Initial staging after NEN diagnosis ("appropriate" in the AUC) and restaging after curative-intent surgery ("may be appropriate" in the AUC) accounted for 221 (9.8%) and 241 (10.7%) scans, respectively. Selection of patients eligible for peptide receptor radionuclide therapy ("appropriate" in the AUC) and restaging after peptide receptor radionuclide therapy completion ("appropriate" in the AUC) accounted for 95 (4.2%) and 115 (5.1%) scans, respectively. The number of scans performed for indications not defined in the AUC was 371 (16.5%). Image result analysis revealed no disease in 669 scans (29.7%), stable disease in 582 (25.9%), and progression in 461 (20.5%). In 99 of the 461 (21.5%) scans, progression was detected on PET but not on CT. Conclusion: Our study provided real-life data that may contribute to support development of ⁶⁴Cu-DOTATATE/SSTR PET/CT guidelines including AUC. Some scenarios listed as "may be appropriate" in the current AUC were frequent in our data. Monitoring of patients with NEN without clinical evidence of progression was the most frequent indication for ⁶⁴Cu-DOTATATE PET/CT, in which disease progression was detected in more than one third, and a large proportion was visible by PET only. We therefore conclude that this scenario could potentially be classified as appropriate.

Investigation of imaging the somatostatin receptor by opening the blood-brain barrier with melittin – A feasibility study using positron emission tomography and [64Cu]Cu-DOTATATE

Article

Author: Strømgaard, Kristian ; Herth, Matthias M ; Gustavsson, Tobias ; Ingemann Jensen, Andreas T ; Kjær, Andreas ; Shalgunov, Vladimir ; Bidesi, Natasha Shalina Rajani ; Andersen, Ida Vang ; Jørgensen, Jesper Tranekjær

DOTATATE is a somatostatin peptide analog used in the clinic to detect somatostatin receptors which are highly expressed on neuroendocrine tumors. Somatostatin receptors are found naturally in the intestines, pancreas, lungs, and brain (mainly cortex). In vivo measurement of the somatostatin receptors in the cortex has been challenging because available tracers cannot cross the blood-brain barrier (BBB) due to their intrinsic polarity. A peptide called melittin, a main component of honeybee venom, has been shown to disrupt plasma membranes and increase the permeability of biological membranes. In this study, we assessed the feasibility of using melittin to facilitate the passage of [⁶⁴Cu]Cu-DOTATATE through the BBB and its binding to somatostatin receptors in the cortex. Evaluation included in vitro autoradiography on Long Evans rat brains to estimate the binding affinity of [⁶⁴Cu]Cu-DOTATATE to the somatostatin receptors in the cortex and an in vivo evaluation of [⁶⁴Cu]Cu-DOTATATE binding in NMRI mice after injection of melittin. This study found an in vitro B_max = 89 ± 4 nM and K_D = 4.5 ± 0.6 nM in the cortex, resulting in a theoretical binding potential (BP) calculated as B_max/K_D ≈ 20, which is believed suitable for in vivo brain PET imaging. However, the in vivo results showed no significant difference between the control and melittin injected mice, indicating that the honeybee venom failed to open the BBB. Additional experiments, potentially involving faster injection rates are required to verify that melittin can increase brain uptake of non-BBB permeable PET tracers. Furthermore, an evaluation of whether a venom with a narrow therapeutic range can be used for clinical purposes needs to be considered.

Abstract::

New drugs being established in the market every year produce specified structures for selective biological targeting. With medicinal insights into molecular recognition, these begot molecules open new rooms for designing potential new drug molecules. In this review, we report the compilation and analysis of a total of 56 drugs including 33 organic small molecules (Mobocertinib, Infigratinib, Sotorasib, Trilaciclib, Umbralisib, Tepotinib, Relugolix, Pralsetinib, Decitabine, Ripretinib, Selpercatinib, Capmatinib, Pemigatinib, Tucatinib, Selumetinib, Tazemetostat, Avapritinib, Zanubrutinib, Entrectinib, Pexidartinib, Darolutamide, Selinexor, Alpelisib, Erdafitinib, Gilteritinib, Larotrectinib, Glasdegib, Lorlatinib, Talazoparib, Dacomitinib, Duvelisib, Ivosidenib, Apalutamide), 6 metal complexes (Edotreotide Gallium Ga-68, fluoroestradiol F-18, Cu 64 dotatate, Gallium 68 PSMA-11, Piflufolastat F-18, 177Lu (lutetium)), 16 macromolecules as monoclonal antibody conjugates (Brentuximabvedotin, Amivantamab-vmjw, Loncastuximabtesirine, Dostarlimab, Margetuximab, Naxitamab, Belantamabmafodotin, Tafasitamab, Inebilizumab, SacituzumabGovitecan, Isatuximab, Trastuzumab, Enfortumabvedotin, Polatuzumab, Cemiplimab, Mogamulizumab) and 1 peptide enzyme (Erwiniachrysanthemi-derived asparaginase) approved by the U.S. FDA between 2018 to 2021. These drugs act as anticancer agents against various cancer types, especially non-small cell lung, lymphoma, breast, prostate, multiple myeloma, neuroendocrine tumor, cervical, bladder, cholangiocarcinoma, myeloid leukemia, gastrointestinal, neuroblastoma, thyroid, epithelioid and cutaneous squamous cell carcinoma. The review comprises the key structural features, approval times, target selectivity, mechanisms of action, therapeutic indication, formulations, and possible synthetic approaches of these approved drugs. These crucial details will benefit the scientific community for futuristic new developments in this arena.

RadioMedix and Vect-Horus announce first dosing of Glioblastoma Multiforme and Pancreatic ductal adenocarcinoma patients with 68Ga-RMX-VH

Houston, TX, USA and Marseille, France, Nov. 15, 2022 (GLOBE NEWSWIRE) -- RadioMedix and Vect-Horus are pleased to announce that they have successfully dosed the first patients in an exploratory Investigational New Drug (eIND) application to evaluate 68Ga-RMX-VH for the diagnostic of Glioblastoma Multiforme (GBM) and Pancreatic ductal adenocarcinoma (PDAC). This radiotracer will serve as a companion diagnostic for future Targeted Alpha Therapy (TAT) for these cancers. 68Ga-RMX-VH is a positron-emitting tomography (PET) agent that targets the Low-Density Lipoprotein Receptor (LDLR) overexpressed in some solid tumors such as GBM and PDAC. The objective of this exploratory study is to evaluate the safety, dosimetry, and bio-distribution of 68Ga-RMX-VH in patients with solid tumors. GBM is the most common malignant primary brain tumor in adults and is a serious and life-threatening disease. PDAC is one of the most chemo-resistant and radio-resistant types of cancers due to the dense pancreatic connective tissue and the diversity of genetic mutations. RadioMedix and Vect-Horus have already signed a co-development and a licensing agreement. Both parties will share the costs of development until Phase 1 for diagnostic and radiotherapy. RadioMedix is leading the clinical development and future commercialization. “Both GBM and PDAC are considered among the most aggressive human cancers. Our current therapeutic approaches for these cancers are invasive and fail meaningful results while adversely effects on the quality of life of our patients. Our approach starts with PET/CT imaging of the diagnostic version of the drug to confirm adequate targeting of the cancers and then applying a therapeutic version of the drug to mainly target the malignant cells while sparing normal organs. All these are accomplished with simple intravenous administration of the drugs.” said Dr Ebrahim Delpassand, Chairman and CEO of RadioMedix. “Another complexity of treating GBM is being able to deliver the drug to the tumor by crossing the blood-brain barrier. Our preliminary results suggest that RMX-VH ligand can accomplish this task”. Added Dr. Delpassand “The favorable results of the first PET/CT imaging scans of GBM and PDAC patients are the culmination of the extensive pre-clinical studies done by RadioMedix and Vect-Horus teams. RadioMedix is serving as a Sponsor and manufacturer of the clinical doses of 68Ga-RMX-VH.”, said Dr. Izabela Tworowska, CSO of RadioMedix. “Our company has a track record in the translation of radiotheranostics drugs, and we are committed to improving diagnosis and therapy of GBM and PDAC", added Dr. Tworowska. “We are excited to have successfully treated the first patients with 68Ga-RMX-VH. The preclinical and preliminary clinical data to date indicates potential diagnostic of this agent and we look forward to generating further evidence as we progress” said Dr. Temsamani, Director of Drug Development of Vect-Horus. “The initiation of this clinical trial is an important milestone for Vect-Horus as it marks the initiation of the clinical program of the imaging candidate, 68Ga-RMX-VH and our transition to a clinical-stage Company. We are looking forward to generating clinical data together with our partner RadioMedix with the aim of improving both diagnostic and therapy for cancer patients and addressing this significant unmet medical need,” said Alexandre Tokay, CEO of Vect-Horus.
