Filter by:This is a Phase 1/2, open-label, first-in-human (FIH) study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary antineoplastic activity of pralsetinib (BLU-667) administered orally in participants with medullary thyroid cancer (MTC), RET-altered NSCLC and other RET-altered solid tumors.
Radiotherapy (combined with chemotherapy) is increasingly applied in the curative treatment of tumours located in the thoracic region (esophageal cancer, lung cancer, breast cancer, and (non) Hodgkin lymphoma). Accurate radiotherapy planning and delivery is essential for the treatment to be effective. However, this accuracy is compromised by tumour and organ motion. Radiotherapy treatment planning is typically performed on a planning-CT scan recorded several days prior to commencement of radiotherapy. Inter-fraction set up variations and organ motion during treatment can lead to differences between the calculated dose distribution on the planning-CT and the radiation dose actually received by the tumour and normal organs. Accurate assessment of these effects is essential to determine optimal margins in order to irradiate the tumour adequately while minimizing the dose to the organs at risk (OARs). In the near future, patients with esophageal cancer, lung cancer, breast cancer and (non) Hodgkin lymphoma are excellent candidates for proton beam therapy (PBT), which enables marked reductions of the radiation dose to the OARs and thus decreasing the risk of radiation induced cardiac and lung toxicity. However, for PBT using pencil beam scanning (PBS), knowledge of tumour and organ motion will be even more important. The potential major advantages of PBS for tumours in the thoracic region are challenged by the respiratory motion of the tumour, breast, esophagus, diaphragm, heart, stomach, and lungs. Setup errors and inter- and intra-fraction organ motion cause geometric displacement of the tumours and normal tissues, which can cause underdosage of the target volumes and overdosage of the organs at risk. Furthermore, it can result in changes in tissue densities in the beam path, which can alter the position of the Bragg peaks and lead to distorted dose distributions. If pencil beam scanning techniques are used to treat moving tumours, there is interplay between the dynamic pencil beam delivery and target motion. This phenomenon can cause additional deterioration of the delivered dose distribution, usually manifesting as significant local under and/or over dosage. It is therefore essential to incorporate motion-related uncertainties during treatment planning. The main objective of this study is to evaluate the impact of inter-fraction tumour and organ motion - while taking into account intra-fraction movements appropriately - on photon and proton radiotherapy treatment planning in order to yield robust intensity modulated photon and/or proton treatment plans. Objective: To evaluate the impact of inter-fraction tumour and organ geometrical dislocation for moving tumours on photon and proton radiotherapy treatment plans in order to create robust intensity modulated photon- and/or proton treatment plans. Study design: Pilot-study (80 patients). Study population: Patients with esophageal cancer (EC), (non) small cell lung cancer ((N)SCLC) stage III, breast cancer, or (non) Hodgkin lymphoma who will be treated with radiotherapy (with or without chemotherapy) with curative intent. Intervention (if applicable): Not applicable. Main study parameters/endpoints: Robustness parameters (homogeneity index; coverage of clinical target volume), dose to organs at risk (OARs), such as the heart (mean heart dose, MHD) and the lungs (mean lung dose, MLD). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: During the radiotherapy treatment course, patients will undergo weekly repeat planning CT scans in treatment position without contrast agents in order to evaluate the impact of inter-fraction tumour and organ motion. Furthermore, additional CBCTs are collected after 10 radiotherapy fractions to assess the intra-fraction motion. The additional radiation dose of these 3-6 4D-CT's and 10 CBCTs is low (4-6 x 25-30mSv + 10 x 7mSv results in an effective dose < 250mSv) compared to the therapeutic radiation dose (40-60Gy). The risks are therefore negligible and the burden is low.
Observational, multicenter study in patients with lung cancer and other thoracic tumors. The GECP, in its commitment to improve the treatment and prognosis of patients with lung cancer and other thoracic tumors, has marked the individualization of treatment according to the expression of markers predictive of response to chemotherapeutic agents and molecular inhibitors of cell proliferation as one of its primary objectives. This could significantly improve the prognosis of patients with lung cancer, and will lead to a radical change in routine clinical practice. The aim of the register is to explore all data available of all patients treated because of thoracic tumours.
The objectives of this study are to explore different dosing levels and schedules of entinostat in combination with pembrolizumab in patients with advanced solid tumors, in terms of safety, tolerability, pharmacokinetics (PK), impact on immune correlatives, and efficacy
The purpose of this study is to evaluate the effect of entinostat on heart rate and other electrocardiogram (ECG) parameters. This study will also evaluate the safety and tolerability of entinostat, as well as pharmacokinetic and pharmacodynamic parameters.
People who may be at increased risk of lung cancer due to age and smoking history will be invited to participate in this international study to determine the best way of using computed tomography (CT) of the chest to screen for early lung cancer. Overseas data show that CT screening (screening tests can find diseases early, when they're easier to treat) can reduce deaths from lung cancer and this study will help determine who is most likely benefit from screening.
Targeted next generation sequencing (NGS) provides a promising method for diagnostic purposes by enabling the simultaneous detection of multiple gene mutations. This study is to evaluate the feasibility and application value by using NGS into identifying genomic mutations in multiple or multifocal primary lung cancers in cell-tumor DNA (ctDNA) from surgical patients
Lung cancer is the second most common cancer in the UK with around 43,500 new patients diagnosed each year. About 69% of patients are diagnosed with advanced stage disease and at present these patients would be expected to survive for less than 12 months. These statistics therefore show the need for the development of new effective drugs in the treatment of advanced Lung cancer. Recent trial results have shown the efficacy of immunotherapy in treating several types of tumours including lung cancer. These tumours are known to express a high level of a glycoprotein called PDL1 which is a component of the PD1 pathway. In cancer the PD1 pathway can be hijacked by tumours leading to the immune system being suppressed. The aim of the new drug Pembrolizumab is to restart the PD1 pathway and use the immune system to help fight the cancer cells. Radiotherapy has also been shown to cause cancer to increase production of the proteins that can block the immune system. Therefore it has been proposed that combine of new immunotherapy agent such as pembrolizumab and radiotherapy in the treatment of lung cancer will allow more cancer cells to be killed through the immune system. The purpose of this study is to see if pembrolizumab can safety be combined with standard palliative radiotherapy in patients with lung cancer. In addition once the patients have completed their course of radiotherapy they will remain on pembrolizumab alone and the study will look at how well this treatment regimen can control the growth of the cancer.
Evaluation of post-operative respiratory complications after thoracic surgery for pulmonary resection in patients with COPD Introduction: Postoperative pulmonary complications following pulmonary resection occur in 12-40% of cases. Some risk factors such as COPD are well identified. It has been shown that COPD patients with a history of frequent exacerbations are more likely to develop exacerbations. No study has evaluated the rate of patients called 'frequent exacerbators' among COPD patients requiring pulmonary resection and the relations between exacerbations history and incidence of acute respiratory postoperative complications. The main objective is to determine the frequency of pulmonary postoperative complications (atelectasis, acute respiratory failure, pneumonia) following lung resection in COPD patients. The secondary objectives are to determine the frequency of extra pulmonary postoperative complications and the prevalence of the 'frequent exacerbator' phenotype in this population, as well as its relation with the risk of post-operative complications. Materials and Methods: This is a prospective, observational, single-center study, of patients with COPD hospitalized for elective thoracic surgery in the center of Thoracic Surgery, Hôpital Cochin. The inclusion criteria are: male or female aged more than 40 years, permanent airflow obstruction as defined by an FEV/FVC ratio < 70% after bronchodilator. Collected data will be: COPD symptoms (dyspnea score, exacerbations) by a questionnaire given to the patient during the anesthesia consultation, COPD severity scores, comorbidities, per operative data, postoperative complications, hospitalization and intra-hospital mortality. Perspectives: This work will provide information on the risk of postoperative complications in patients with COPD and the influence of the 'frequent exacerbator' phenotype. This will help adapting preventive care to the COPD subtype .
SPECTAlung is a program aiming at screening patients with thoracic tumors to identify the molecular characteristics of their disease. The thoracic tumors include lung cancer, malignant pleural mesothelioma, thymoma or thymic carcinoma at any stage. Once the molecular characteristics are identified, there might be the possibility to offer these patients access to targeted clinical trials.
