Based on the high expression of specific receptors on the surface of diseased tissues and neovascularization, noninvasive targeted molecular imaging can be used to visualize lesions in vitro by combining specific ligands labeled with short half-life isotopes. In this study, a novel dual-target imaging agent 68Ga-RM26-RGD was used for clinical study of tumor PET/CT imaging to further verify its clinical application value.
This is a phase II clinical trial to evaluate the capability of 68Ga-labeled targeted covalent radiopharmaceutical (TCR) fibroblast activation protein inhibitor (FAPI) PET/CT to guide the surgical treatment of medullary thyroid carcinoma (MTC). The surgical extent of MTC is determined based on the lesion range revealed by 68Ga-TCR-FAPI PET/CT, with the main endpoint being 1-month post-surgical calcitonin level.
Bevacizumab can be an effective treatment for individuals with NF2 and improve different nerve functions (like hearing, tinnitus or balance problems) and the quality of life of NF2 patients. However, bevacizumab is not effective in all patients or all tumors, at the cost of moderate toxicity and considerable financial burden. Therefore, this observational study will validate an imaging biomarker method to predict bevacizumab efficacy in order to avoid adverse effects and high costs in non-responders to bevacizumab treatment. Patients will undergo standard-of-care treatment with the sole addition of a pre-treatment 89Zr-Bevacizumab PET/CT-scan. Per standard-of-care bevacizumab...
There is no consensus in the literature on the best way to treat cystic lesions of the pituitary area. Patients who are symptomatic from these tumours are rare. The cystic form of tumours present special challenges since traditional treatment modalities (surgery and/or external radiation) are often not able to completely remove or treat the cyst wall without major morbidity or even mortality. There is no 'best practice' for the treatment of cystic tumours per se. Treatments available to patients with cystic sellar/parasellar tumours include conservative management using a 'wait and scan' approach, cyst drainage, and cyst removal via transsphenoidal and/or craniotomy approach...
This will be an open-label, single-arm, national phase 1/2 therapeutic study to evaluate the safety, tolerability, and preliminary efficacy of [90Y]Y-PentixaTher ([90Y]Y-PTT) for the treatment of recurrent or refractory primary or isolated secondary central nervous system (CNS) lymphoma. The study will be performed in three cohorts with different dose levels according to the best-of-5 dose escalation design. A safety review committee (SRC) will evaluate dose-limiting toxicities and decide about escalation and de-escalation. Eligible patients will receive one cycle of [90Y]Y-PTT, which will be administered intravenously. There will be no comparator in this study. Safety,...
The goal of this clinical trial is to evaluate the value of 99mTc-CNDG for diagnosis of brain tumors by comparing it with 18F-FDG-PET. The main questions it aims to answer are: 1. What is the diagnostic consistency between 99mTc-CNDG and 18F-FDG? 2. What is the correlation between the SUVmax value of 99mTc-CNDG and tumor type? Participants will: Receive18F-FDG-PET and 99mTc-CNDG examination within 2 weeks before surgery. Obtain pathological diagnosis by surgery or biopsy as the gold standard.
This is a phase 0/I exploratory study. Patients at first or second recurrence of glioblastoma will be enrolled. The study will be divided into two cohorts: Cohort A (safety cohort) and Cohort B (surgical patient cohort). Cohort A: Eligible patients will be sequentially enrolled to receive intravenous domvanalimab combined with zimberelimab (N=6). Domvanalimab will be given at a dose of 10 mg/kg and zimberelimab will be given at a dose of 240 mg (flat). The dosing was determined in a separate study in solid tumors; this cohort will confirm the safety of the dosing schedule in patients with brain tumors. Cohort B: Expansion surgical cohort. The purpose of cohort B is to provide...
TScan Therapeutics is developing cellular therapies across multiple solid tumors in which autologous participant-derived engeneered T cells are engineered to express a T cell receptor that recognizes cancer-associated antigens presented on specific Human Leukocyte Antigen (HLA) molecules. This is a multi-center, non-randomized, multi-arm, open-label, basket study evaluating the safety and preliminary efficacy of single and repeat dose regimens of TCR'Ts as monotherapies and as T-Plex combinations after lymphodepleting chemotherapy in participants with locally advanced, metastatic solid tumors disease.
Surgery plays significant role in treatment of neurogenic tumors, both for benign ganglioneuroma and for high risk neuroblastoma. The world literature has accumulated large experience in laparoscopic surgery for abdominal neuroblastoma. The presence of IDRF (image-defined risk factors) and tumor size (>4-7 cm) are considered as common contraindications for minimally invasive surgery in neuroblastoma. However, the recent studies have shown that presence of IDRF is not an absolute contraindication for laparoscopic surgery. This open-label, nonrandomized, observational, phase III evaluates role and weight of different surgical risk factors (including IDRF, tumor size,...
This is a single-arm, phase II study that will enroll a total of 45 subjects. All subjects will have a confirmed diagnosis of metastatic or unresectable soft tissue sarcoma or bone sarcoma. All subjects must have intact Rb, identified at the time of screening, by immunohistochemistry testing of submitted tumor specimen. Subjects will receive Abemaciclib 200 mg twice daily until progression or discontinuation criteria are met.
