NCT03647358
The purpose of this study is to evaluate a new diagnostic imaging test, positron emission tomography (PET), with a different radioactive form of iodine called iodine-124. This form is able to accurately measure the amount of radioactive iodine uptake in the cancer. If the new test determines sufficient radioiodine uptake in the cancer, treatment will continue as usual. However, if the new test shows only low radioiodine uptake, a decision may be made that the benefit from radioiodine therapy is insufficient and that another form of therapy is preferred.

The study will be an effectiveness study. The study will include enrollment of a total of 20 patients with at least one PC lesion for ultrasound guided RFA to PC recurrence in the neck to assess the effectiveness in reducing patient's hypercalcemia. Patients will have surgically proven PC from prior parathyroidectomy and suspicious PC visible on ultrasound and request for treatment for uncontrolled hypercalcemia (Figure 1).
NCT07383246
This is a multicenter, randomized, open-label, non-inferiority Phase III clinical trial, aims to compare 68Ga-CTR-FAPI PET-CT-guided surgery to investigator-chosen surgical approaches to evaluate its efficacy in treating newly diagnosed medullary thyroid carcinoma. This study plans to enroll 150 newly diagnosed MTC patients, who will be randomly assigned in a 2:1 ratio to the experimental group (surgery based on 68Ga-CTR-FAPI PET-CT findings) and the control group (surgery based on the investigator's choice). The primary endpoint is the biochemical cure rate, with secondary endpoints including the biochemical cure rate in the R0 resection subgroup, the unnecessary dissection rate in the biochemical-cured subgroup, 3-year recurrence-free survival, the rate of change in surgical extent, and diagnostic accuracy.
NCT06639191
The goal of this clinical trial is to evaluate the safety and tolerability of increasing doses of \[177Lu\]Lu-AKIR001, both in relation to tolerable activity of lutetium-177 and the absorbed protein mass dose of AKIR-001 in patients with irresectable or metastatic CD44v6-expressing solid malignancies for whom no reasonable systemic treatment options are be available. The main question it aims to answer is: • What is the toxicity profile of the study drug \[177Lu\]Lu-AKIR001 according to the rate of Dose Limiting Toxicities and (Severe) Adverse Events? Participants will receive one \[177Lu\]Lu-AKIR001 infusion followed by a 6-week safety follow-up period, which can be extended up to 12 weeks. Possible additional infusions of the trial drug, up to a maximum number of four, can be given when clinical benefit is noted and toxicity is deemed acceptable.
NCT07252661
This is a research study of an experimental drug called ACC-1898. ACC-1898 is an oral tyrosine kinase inhibitor (TKI) that blocks several proteins kinases which may help cancer cells grow and spread. The purpose of this Phase 1 clinical trial is to find a safe dose of ACC-1898 and to understand how the body absorbs, distributes, and eliminates the drug (pharmacokinetics / PK). The study will also look for early signs that ACC-1898 may slow or shrink tumors and explore possible biological markers related to drug activity. Adults with advanced or metastatic solid tumors who have no remaining standard treatment options may take part. All participants will receive ACC-1898 tablets by mouth once daily in repeating 21-day cycles. Treatment may continue for up to two years if the cancer does not worsen and side effects are manageable. Safety information, laboratory results and imaging scans (CT or MRI) will be collected regularly. The study will first test different dose levels (dose-escalation phase) and may later expand enrollment in selected tumor types once a recommended dose is found.
NCT04624477
This is a prospective, observational, multi-center study examining the long-term outcomes of patients with small, low risk papillary thyroid cancer who offered the choice of active surveillance (close follow-up to monitor for potential disease progression) or immediate surgery.
NCT06790706
Immune checkpoint inhibitors (ICI) have revolutionized the management of advanced cancers. However, most rare cancers have been excluded from this progress due to the lack of clinical trials involving these diseases. After the standard first-line treatment, there are no other validated treatments for most of them. The management of these patients in ≥ 2nd line treatment relies on historic poorly effective regimens. This creates an inequity between patients with frequent cancers beneficiating from medical progresses and approvals of innovative drugs, and patients with rare cancers are still treated with old and toxic drugs. Few available data on case reports and early phase studies indicate a beneficial role of the immunotherapy in rare cancers. The investigators assume that the combination of Domvanalimab and Zimberelimab is more effective than historical standard treatments in patients with 5 types of advanced rare cancers, after failure of at least one line of standard treatment in the advanced setting: * Cohort 1: Peritoneal Mesotheliomas (PM) * Cohort 2: Gestational Trophoblastic Tumors (GTT) * Cohort 3: B3 Thymomas and Thymic Carcinomas (TET) * Cohort 4: Refractory Thyroid Carcinomas (ATC) * Cohort 5: GEP-NET and carcinoid tumors (GEP-NET (Gastroenteropancreatic neuroendocrine tumors)/TCT (Thoracic carcinoid tumor)/UP-NET (Neuroendocrine tumor of unknown primary)) The primary objective is to assess the efficacy of the combination of Domvanalimab and Zimberelimab in terms of progression-free survival rate at 24 weeks (for cohorts 1,3,5), successful hCG (Human Chorionic Gonadotropin) normalisation rate at 24 weeks for cohort 2 and survival rate for cohort 4. The secondary objectives are to assess the efficacy of the combination of anti-TIGIT (T cell Immunoreceptor with Ig and ITIM domains) and anti-PD-1 (Programmed Death-1) immunotherapies in terms of overall response rate, progression-free survival (cohort 1-3 and 5), resistance-free survival (cohort 2), overall survival (cohorts 1-3 and 5), duration of the response (cohorts 1-3 and 5); and to assess the tolerability of the doublet of immunotherapy in terms of adverse events. Patients will be treated until disease progression or alternatively 2 years in case of complete response (upon discussion with the coordinator of the study, the coordinator of the cohort and the investigator), unacceptable toxicity, or death. At the end of treatment, patients will be followed up for at least 1 year. IMMUNORARE5 is composed of five independent open-label national multicenter single-arm phase II trials, sponsored by Lyon University Hospital, led in collaboration with the corresponding French national reference centers, with a centralized coordination by a dedicated team. Each phase II trial is designed as a two-stage Simon design, with early termination for futility. For each cohort, a null hypothesis (H0) and an alternative hypotheses (H1) regarding the percentages of patients with success has been defined, with 5% one-sided alpha level and 80% power. The trial will be conducted in 15 French Centers with an inclusion period of 36 months
NCT06359847
ST-1898, a multi-targeted tyrosine kinase inhibitor, has demonstrated strong inhibitory activity for VEGFR2, c-MET, AXL, PDGFRA, RET, KIT, etc. The primary purpose of this study is to evaluate the efficacy of ST-1898 tablets in patients with locally advanced or metastatic RAIR-DTC after failure of at least first-line TKI systemic therapy. All subjects will receive ST-1898 180 mg orally once daily until disease progression or intolerable toxicity.
NCT07138716
This study explores the clinical application of 68Ga-DOTA-CCK-FS PET/CT in detecting cholecystokinin-2 receptor (CCK-2R)-positive tumors, particularly medullary thyroid cancer (MTC) and other malignancies. Led by Prof. Luo Yaping (PUMCH Nuclear Medicine) and Prof. Liu Zhibo (Peking University, radiochemistry expert), the trial will enroll 30-40 patients to compare 68Ga-DOTA-CCK-FS imaging with standard PET/CT (e.g., 18F-FDG or 68Ga-DOTATATE). The novel tracer shows higher tumor uptake and retention in preclinical studies, potentially improving diagnosis and treatment guidance for aggressive, CCK-2R-expressing cancers. The study leverages PUMCH's Class IV Radioactive Drug License for advanced radiopharmaceutical development. Risks are minimal (diagnostic radiation dose only), and participants receive free imaging assessments. Results aim to refine precision diagnostics for MTC and related tumors.
NCT07062211
This research will employ cross-sectional analytical to determine diagnostic accuracy of Flourodeoxyglucose-18 Positron Emission Computed Tomography in the evaluation of Recurrent Papillary Thyroid Carcinoma with patient's raised Thyroglobulin level in Lahore.
NCT05534594
Rationale: In patients with medullary thyroid cancer (MTC), molecular imaging is used to assess the extent of disease in the primary diagnostic process and follow-up period to determine possible therapeutic options. The currently most used tracer in clinical practice, F-18 labelled fluorodeoxyglucose (18F-FDG), does not accurately detect MTC tumors with an indolent growth rate. A new, complimentary tracer is warranted to detect different subtypes. Objective: The primary objective is to assess the feasibility of using the F-18 labelled prostate specific membrane antigen (18F-PSMA) PET/CT for (re)staging patients with medullary thyroid cancer. The secondary objective is to compare the ability to detect MTC with the 18F-PSMA PET/CT to that of the 18F-FDG PET/CT. Study design: Prospective, single-centre, feasibility study. Study population: Patients (18 years of age or older) with biochemically and cytological/histological confirmed MTC, for whom the indication of an 18F-FDG PET/CT for tumor staging has already been determined on clinical grounds. Main study parameters/endpoints: The primary outcome of this study is the performance (lesion-based//patient-based sensitivity) of the 18F-PSMA PET to detect MTC lesions in patients with cytologically/histologically confirmed disease. Secondarily, the performance of the 18F-PSMA PET will be compared to the 18F-FDG PET/CT.
NCT06931743

It will also be combined with the Internet of Things technology to develop artificial intelligence equipment or applications to achieve remote monitoring and intelligent alarm, and improve the timeliness and initiative of pain management after thyroidectomy. In the future, we will further carry out a series of research work to explore the possible analgesic mechanisms through molecular biology and neurophysiology.
NCT06422702
The psychosomatic symptoms of patients with differentiated thyroid cancer (DTC) during the initial treatment phase need to be improved. Stress coping training aims to reshape an individual's perception of stress and provide skill training, thereby influencing how they cope in stressful situations. Symptom management theory emphasizes improving health outcomes by helping individuals perceive and manage their symptoms. Therefore, this clinical trial combines stress coping training and symptom management theory to construct and test an intervention program for psychosomatic symptoms in DTC patients. The main questions it aims to answer are: * Does the psychosomatic symptom intervention alleviate participants' levels of anxiety and depression? * Does the psychosomatic symptom intervention promote participants' achievement of TSH suppression therapy standards? * Does the psychosomatic symptom intervention enhance participants' self-management efficacy? * Does the psychosomatic symptom intervention improve participants' shoulder joint function? Researchers will compare the psychosomatic symptom intervention with continuous psychological care (a form of comforting care) to determine if the intervention better promotes participants' psychosomatic health. 1. Before conducting this clinical trial, researchers conducted qualitative interviews with DTC patients and healthcare providers, followed by literature analysis and expert consultations to develop a psychosomatic symptom intervention program for DTC patients during the initial treatment phase. 2. A total of 84 DTC patients in the initial treatment phase were recruited and randomly grouped into two blocks. The intervention group received a 12-week psychosomatic symptom intervention in addition to routine care, while the control group received 12 weeks of continuous care. Data were collected before the intervention, at the end of the intervention, 3 months after the intervention, and 6 months after the intervention. The psychosomatic symptom intervention mainly includes: * Psychological module: symptom logs, meditation, positive psychology, and emotional management * Physiological module: gargling exercises, "T" exercises, "米" exercises, and shoulder-neck exercises * The psychosomatic module aims to intervene at three levels: individual, environmental, and health and disease. The individual level includes role management and self-awareness. The environmental level includes resource utilization, family support, peer support, and social support. The health and disease level includes disease management, individual counseling, and progressive muscle relaxation training. * The intervention is divided into three stages: concept formation, skill acquisition and repetition, and application and completion. These stages are further divided into six sub-stages, each containing content from the psychological, physiological, and psychosomatic modules.

NCT06095362
Background: Papillary thyroid cancer (PTC) patients often develop central lymph node metastases (CLNM), which pose a high risk of disease recurrence. The prophylactic central lymph node dissection (PCLND) is controversial, with proponents arguing for it to prevent local recurrence, and opponents objecting to the hypoparathyroidism and nerve damage risk. Currently, no diagnostic tool exists to identify patients who would benefit from a PCLND. Molecular Fluorescence Guided Surgery (MFGS) is a potential solution that uses fluorescent tracers to detect cancerous tissue. This study aims to investigate whether the administration of a GMP-produced near infrared (NIR) tracer, bevacizumab-IRDye800CW, targeting VEGF-A, can enable intraoperative selection of PTC/FTC/HTC patients for CLND. Objective: The primary objective of the study is to determine the optimal dose of bevacizumab-IRDye800CW for an adequate tumor-to-background ratio (TBR) in PTC/FTC/HTC lymph node metastases. The secondary objectives are to evaluate the feasibility of MFGS for PTC/FTC/HTC and nodal metastasis assessment, to correlate and validate fluorescence signals detected in vivo with ex vivo histopathology and immunohistochemistry, to evaluate the distribution of bevacizumab-IRDye800CW on a microscopic level, and to quantify the sensitivity and specificity of bevacizumab-IRDye800CW for PTC/FTC/HTC and nodal metastasis. Study Design: The TARGET-BEVA study is a non-randomized, non-blinded, prospective, single-center phase I feasibility study for patients with confirmed PTC/FTC/HTC, for which the best TBR dosage group in PTC/FTC/HTC nodal metastasis will be determined. The study will initiate with a 3 x 3 scheme: 4,5 mg, 10 mg, and 25 mg, with three patients confirmed with lymph node metastasis in each group. Dosages will be based on previous studies, with the primary objective being the detection of lymph node metastasis. After the first 9 patients, an interim analysis will be performed, after which the best dosage group will be expanded with another 7 patients. Conclusion: The study aims to identify a novel diagnostic tool that can aid clinicians in selecting patients for PCLND, enabling a reduction in overtreatment, morbidity, and costs while maintaining effectiveness with a lower recurrence rate and improved quality of life.
NCT05507775
Non-medullary thyroid carcinoma has a good prognosis in most patients. However, a small subset of patients nevertheless develop metastatic or locally advanced and unresectable disease which in some cases also becomes radioiodine refractory. In these patients treatment options are very limited. Earlier cell line and animal studies have shown that digoxin can reinduce radioiodine uptake in non-medullary thyroid cancer. This study serves as a proof of principle study to assess the possibility of digoxin to reinduce radioiodine uptake in adult humans with metastatic or locally advanced non-medullary radioiodine refractory thyroid carcinoma.
NCT05949424
The study hypothesis is that a lower starting dose of anticancer tablet treatments can lead to better treatment tolerability in older patients, while the benefits of treatment can be the same. The trial population consists of 30 patients aged 65 years or older, who are starting treatment with one of these anti cancer tablet treatments: pazopanib, olaparib, lenvatinib, sunitinib or palbociclib. The control group (half of the participants) will be treated with the standard-of-care, the interventional group will start with the lowest dose of the anti cancer tablets as described in the drug label. The dose will be increased every two weeks in case of good tolerability. Results of this pilot study will be used to inform the design of the larger randomised phase 2 trial.
NCT06067594
Medullary thyroid carcinoma (MTC) is a tumor originating from parafollicular C cells of the thyroid. (1) Representing 1 to 7% of all thyroid carcinoma cases (2, 3, 4). It can occur in two clinical forms, the sporadic or non-hereditary, in 75-80% of patients, and the hereditary form in the remaining 20-25%. It can be part of different clinical syndromes depending on the organs involved: Multiple Endocrine Neoplasia type 2A (MEN2A), Multiple Endocrine Neoplasia type 2B (MEN2B) and Familial Medullary Thyroid Carcinoma (FCM) whose clinical expression is only CMT. A distinctive characteristic of this tumor is its capacity to secrete calcitonin (CT), which, measured in serum, sanctions suspicion of this pathology (5-8) leading to diagnostic studies to confirm CMT. For the preoperative diagnosis of thyroid nodules, ultrasound-guided fine-needle aspiration cytology (FNAC) is a useful and safe procedure; however, its sensitivity to exclude CMT is low (9-15). In 2015, a meta-analysis of 15 studies (16) found that the accuracy of FNAC in diagnosing CMT was around 50%. For this reason, other studies have indicated that the measurement of calcitonin in the fine-needle lavage aspirate fluid of thyroid nodules (CT-guided FNAC), which have suspected medullary carcinoma, can significantly improve the accuracy in the diagnosis of MTC (17 -19). Therefore, clinical practice guidelines recommend its determination in patients with suspected MTC (1,2). The diagnostic importance of pre-surgical medullary carcinoma lies mainly in two points: first, it changes the surgical approach of the patients, and second, it allows one to rule out associated pathologies such as hyperparathyroidism and pheochromocytoma, which are associated when the entity is hereditary. The performance of CT-guided FNAC by the chemiluminescent (CL) method has been widely disseminated. However, to the best of our knowledge, to date there are no data available on the appropriate cut-off value of CT-guided FNAC with calcitonin electrochemiluminescence (ECL) immunometric assay method. As previously stated, it is of particular interest to determine the calcitonin cut-off point in needle washing by electrochemiluminescence method that allows diagnosing medullary carcinoma. Clarifying this point allows improving the approach to patients in whom medullary carcinoma is suspected. This work seeks to determine the cut-off point of CT-guided FNAC for the diagnosis of CMT with the ECL assay method.
NCT05178186
The impact of the COVID-19 pandemic has heavily influenced routine medical care. In the first months of the pandemic, healthcare authorities restricted medical care to emergency procedures, postponing elective surgical activity. Conversely, screening programmes and planned examinations have been temporarily suspended or delayed. Gradually, elective surgery and clinical activities have resumed, thanks to the weakening of the pandemic, to a better organization of the healthcare systems and to the diffusion of COVID-19 vaccines. In the present study, we aim to evaluate the impact of the COVID-19 pandemic on surgery for thyroid carcinoma. Particularly, we aim to investigate whether the delay in operations, screening programmes, and planned examinations for patients under follow-up after thyroid surgery have led to an increased number of aggressive tumours. To evaluate this aspect, we aim to compare the patients who had undergone thyroidectomy for thyroid cancer before the COVID-19 pandemic (from February 2019 to February 2020), during the first phase of the pandemic (from March 2020 to September 2020), and after the first phase of the COVID-19 pandemic (from October 2020 to October 2021).
