This phase I trial compares electronic cigarette (EC) user preferences and smoking behaviors of nicotine analogs to nicotine to improve the understanding of nicotine analog addictiveness. Over the last ten years, EC use has become a major concern due to its increased use among adolescents and young adults. Though progress has been made in regulating nicotine containing products, some companies have shifted toward producing products containing nicotine analogs. ECs are battery-powered electronic devices designed to atomize a nicotine (the poisonous chemical found in tobacco)-containing liquid solution for inhalation in a manner that simulates smoking a tobacco cigarette. When nicotine enters the body, it causes an increased heart rate and use of oxygen by the heart, and a sense of well-being and relaxation. Nicotine analogs are compounds that are similar to nicotine in their chemical structure. Some nicotine analogs have been shown to have nicotine-like effects; however, more research is needed to prove they function similarly to nicotine and/or have similar effects. Comparing EC user preferences and smoking behaviors of nicotine analogs to nicotine may help improve the understanding of nicotine analog addictiveness. Additionally, combustible cigarette smoking is well-known to have deleterious effects on cardiovascular health. High blood pressure is one of the major health consequences of cigarette smoking and can increase the risk of hypertension, heart attack, and stroke. Although ECs have been marketed as a less harmful alternative to cigarette smoking, clinical trials have shown that vaping ECs can also lead to acute increases in blood pressure and heart rate. Nicotine can alter vascular reactivity by promoting the release of vasoconstrictors and suppressing the production of vasodilators. No research has examined how the synthetic nicotine in ECs affects hemodynamics, vascular health, and endothelial function. Assessing acute cardiovascular responses to nicotine analogs is therefore critical to enhancing our understanding of the potential cardiovascular risks associated with vaping ECs containing synthetic nicotine.

The investigators use natural language processing and a hierarchical transformer model to analyse 1.2 million social media posts (Weibo, Douyin, Xiaohongshu, WeChat) for psychological distress and suicide ideation, with prospective validation of an AI Early Warning System.
NCT06487481
Background: Adrenocortical carcinoma (ACC) is a rare cancer of the adrenal glands. ACC often returns after tumors are removed with surgery. Less than 35% of people with ACC survive 5 years after diagnosis. Objective: To test a new type of external beam RT before surgery in people with ACC. Eligibility: People aged 18 years and older with ACC that came back after treatment but may be safely removed with surgery. Design: Participants will be screened. They will have a physical exam with blood and urine tests. They will have tests of their heart function. They will have imaging scans. A small sample of tumor tissue may be collected if one is not available. They will undergo laparoscopy: Small incisions will be made in the abdomen so that a thin tube with a light and camera can be inserted to view the organs. RT comes from a machine that aims radiation at tumors. Participants will receive preoperative RT in daily fractions over approximately 2-3 weeks, followed by a planned surgical resection about 4 weeks after the completion of RT. Visits will last 30 to 60 minutes. Participants will undergo surgery to remove their tumors about 4 weeks after they finish RT. They will stay in the hospital 1 to 3 weeks after surgery. Participants will have follow-up visits for 10 years after surgery.
NCT04214067
This phase III trial compares whether the addition of pembrolizumab to radiation therapy is more effective than radiation therapy alone in reducing the risk of cancer coming back (recurrence) in patients with newly diagnosed stage I-II endometrial cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. The addition of pembrolizumab to radiation treatment may be more effective than radiation treatment alone in reducing cancer recurrence.
NCT05050162
This phase II/III trial compares whether cisplatin given weekly with radiation therapy is better tolerated than cisplatin given every three weeks with radiation therapy for the treatment of head and neck cancer that has spread to other places in the body (advanced). The second part of this study will also help to find out if the cisplatin given weekly approach will extend patients' life by at least the same amount of time as the cisplatin given every three weeks approach. Cisplatin is in a class of medications known as platinum-containing compounds that work by killing, stopping or slowing the growth of cancer cells. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Radiation with low-dose cisplatin given weekly may be effective in shrinking or stabilizing head and neck cancer or preventing its recurrence.
NCT04358276
This trial studies the impact of a 12-month invention focused on early detection of skin cancer and timely follow up in patients who underwent stem cell transplant and their primary care providers. Some stem cell transplant survivors may develop complications related to the treatment they received. Many of these complications may not be known for years after the treatment and preventive measures can be taken to reduce the chances that a complication will occur and encourage early detection. This study focuses on one complication that stem cell transplant survivors are at high risk of developing - skin cancer. An early diagnosis of skin cancer is important since the cancer is usually smaller, requires less extensive treatments, and has better outcomes. Teaching skin self-examination and encouraging patients to alert doctors to skin changes may provide an important opportunity for early detection of skin cancer.
NCT06532279
This phase II trial compares the effectiveness of adding BMX-001 to usual symptom management versus usual symptom management alone for reducing oral mucositis in patients who are receiving chemoradiation for head and neck cancer. Oral mucositis (inflammation and mouth sores) is a common side effect of chemoradiation that can cause pain and difficulty swallowing. Usual management of these side effects typically consists of using mouth rinses and pain medications during treatment and for several weeks after completion of treatment. BMX-001 neutralizes harmful substances in the body, preventing damage to macromolecules such as DNA and minimizes free radical-related toxicity in normal tissues. Adding BMX-001 to usual symptom management may be more effective than usual symptom management alone at reducing oral mucositis in patients receiving chemoradiation for head and neck cancer.
NCT07321210
The goal of this clinical trial is to learn if adding a template lymph node dissection (TLND) to the standard surgery for upper tract urothelial cancer (UTUC) can improve patient survival and prevent the cancer from recurrence. The main questions it aims to answer are: Do patients who receive standard surgery with LND live longer without their cancer returning? Is adding LND safe, and how does it affect surgery-related complications? Researchers will compare the group receiving standard surgery plus LND to the group receiving standard surgery alone to see if adding LND is more effective. Participants will: Be randomly assigned to one of the two surgical groups. Undergo their assigned surgery and recover in the hospital. Attend regular follow-up visits for checkups and scans for 5 years to monitor for cancer recurrence, with the possibility of long-term follow-up extending to 10 years.
NCT00102544
This study will evaluate the accuracy and effectiveness of an experimental tracking device for locating abnormalities during invasive procedures, such as biopsy or ablation, that cannot easily be visualized by usual imaging techniques, such as computed tomography (CT) scans or ultrasound. Some lesions, such as certain liver or kidney tumors, small endocrine abnormalities, and others, may be hard to find or only visible for a few seconds. The new method uses a needle with a miniature tracking device buried inside the metal that tells where the tip of the needle is located, somewhat like a mini GPS, or global positioning system. It uses a very weak magnet to localize the device like a miniature satellite system. This study will explore whether this system can be used in the future to more accurately place the needle in or near the desired location or abnormality. Patients 18 years of age and older who have a lesion that needs to be biopsied or an ablation procedure that requires CT guidance may be eligible for this study. Candidates are screened with a medical history and review of medical records, including imaging studies. Participants undergo the biopsy or ablation procedure as they normally would, with the following exceptions: some stickers are placed on the skin before the procedure and a very weak magnet is placed nearby. The needles used are similar to the ones that would normally be used except that they contain a metal coil or spring buried deep within the needle metal. The procedure involves the following steps: 1. Small 1-cm plastic donuts are place on the skin with tape. 2. A planning CT scan is done. 3. The CT scan is sent to the computer and matched to the patient's body location with the help of a very weak magnet. 4. The needle used for the procedure is placed towards the target tissue or abnormality and the "smart needle" location lights up on the old CT scan. 5. A repeat CT is done as it normally is to look for the location of the needle. 6. After the procedure the CT scans are examined to determine how well the new tool located the needle in the old scan.
NCT07668037
This study is a retrospective, multicenter, observational cohort study in patients with advanced or locally advanced non-small cell lung cancer (NSCLC). The aim of this study was to establish a long-term survival (LTS) versus short-term survival (STS) real-world cohort, to systematically characterize the multi-omics landscapes, and to develop and validate an artificial intelligence (AI) pathological prediction model based on routine H\&E-stained images for predicting immune microenvironment features and long-term survival outcomes following immunotherapy.
NCT03186898
This phase III trial studies how well radiation therapy with protons works compared with photons in treating patients with liver cancer. Radiation therapy, such as photon therapy, uses high energy x-rays to send the radiation inside the body to the tumor while proton therapy uses a beam of proton particles. Proton therapy can stop shortly after penetrating through the tumor and may cause less damage to the surrounding healthy organs and result in better survival in patients with liver cancer.
NCT03088540
The primary objectives of the study are: * To compare the overall survival (OS) of cemiplimab versus standard-of-care platinum-based chemotherapies in the first-line treatment of patients with advanced or metastatic non-small cell lung cancer (NSCLC) whose tumors express PD-L1 in ≥50% of tumor cells * To compare the progression-free survival (PFS) of cemiplimab versus standard-of-care platinum-based chemotherapies in the first-line treatment of patients with advanced or metastatic NSCLC whose tumors express PD-L1 in ≥50% of tumor cells The key secondary objective of the study is to compare the objective response rate (ORR) of cemiplimab versus platinum-based chemotherapies
NCT06500481
This phase III trial compares proton craniospinal irradiation (pCSI) to involved-field radiation therapy (IFRT) for the treatment of breast or non-small cell lung cancer that has spread from where it first started to the cerebrospinal fluid filled space that surrounds the brain and spinal cord (leptomeningeal metastasis). Patients with leptomeningeal metastasis (LM) may develop multiple areas of nervous system (neurologic) impairment that can be life-threatening. Radiation therapy (RT) effectively relieves local symptoms due to LM. RT uses high energy radiography (x-rays), particles, or radioactive seeds to kill cancer cells and shrink tumors. IFRT is commonly used to treat symptoms of LM. IFRT is radiation treatment that uses x-rays to treat specific areas of LM and to relieve and/or prevent symptoms. pCSI uses protons that can be directed with more accuracy than x-rays which allows treatment of the entire central nervous system space containing the cerebrospinal fluid (CSF), brain, and spinal cord. The pCSI treatment could delay the worsening of LM. Giving pCSI may be better than IFRT in treating LM in patients with breast or non-small cell lung cancer.
NCT07665190
This clinical trial aims to evaluate the efficacy and safety of Becotatug Vedotin (EGFR-ADC) in combination with Pucotenlimab(Anti-PD-1 Monoclonal Antibody) as neoadjuvant therapy for patients with Resectable Locally Advanced Hypopharyngeal Squamous Cell Carcinoma. The primary objective is the pathological complete response(pCR)rate following neoadjuvant therapy. The secondary objective includes the major pathological response(MPR)rate following neoadjuvant therapy, the objective response rate (ORR), Organ preservation rate, Surgery postponement rate, event-free survival (EFS), overall survival(OS), and safety.
NCT05256225
This phase III trial tests whether adding trastuzumab and hyaluronidase-oysk (Herceptin Hylecta \[TM\]) or pertuzumab, trastuzumab and hyaluronidase-zzxf (Phesgo \[TM\]) to the usual chemotherapy (paclitaxel and carboplatin) works to shrink tumors in patients with HER2 positive endometrial cancer. Trastuzumab and pertuzumab are monoclonal antibodies and forms of targeted therapy that attach to specific molecules (receptors) on the surface of tumor cells, known as HER2 receptors. When trastuzumab or pertuzumab attach to HER2 receptors, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Hyaluronidase is an endoglycosidase. It helps to keep pertuzumab and trastuzumab in the body longer, so that these medications will have a greater effect. Hyaluronidase also allows trastuzumab and trastuzumab/pertuzumab to be given by injection under the skin and shortens their administration time compared to trastuzumab or pertuzumab alone. Paclitaxel is a taxane and in a class of medications called antimicrotubule agents. It stops tumor cells from growing and dividing and may kill them. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Giving Herceptin Hylecta or Phesgo in combination with paclitaxel and carboplatin may shrink the tumor and prevent the cancer from coming back in patients with HER2 positive endometrial cancer.
NCT07660627
Preoperative neoadjuvant chemotherapy is the standard treatment for locally advanced gastrointestinal tumours. However, not all patients respond to preoperative treatment. Early identification of progression during neoadjuvant chemotherapy or diagnosis of early disease relapse during adjuvant treatment is essential to modify the treatment strategy. The aim of this project is to validate ctDNA as a biomarker of molecular relapse/progression of disease.
NCT06840886
This is a multi-center, first-in-human (FIH), open-label, Phase 1a/1b dose escalation and dose expansion study to assess the safety, PK, pharmacodynamics, and antitumor activity of PHST001 monotherapy (Phase 1a) or in combination with chemotherapy (Phase 1b) in adult participants with advanced relapsed and/or refractory solid tumors (including but not limited to CNS tumors in Phase 1a only). In Phase 1b cohort expansions, the study will focus on participants with advanced relapsed and/or refractory ovarian cancer, endometrial cancer, and cholangiocarcinoma. The study's primary objective is to evaluate the safety and tolerability of PHST001 and determine the RP2D (Recommended Phase 2 dose) of PHST001 monotherapy and in combination with chemotherapy as well as assess the anti-tumor activity of PHST001 and chemotherapy in Phase 1b.
NCT06813079
The purpose of this study is to see if using Patient Derived Organoids (PDO) to choose a drug for the treatment of pancreatic cancer individually for each patient is useful. The study will look at the number of participants who have a response to their assigned drug.
NCT05024773
This is a phase III, single-arm, multicenter, international study to assess the efficacy and safety of ONCOFID-P-B following intravesical instillation in adult patients with histologically and cytologically confirmed CIS, with or without concomitant Ta-T1, who are unresponsive to BCG therapy and unwilling or unfit to undergo radical cystectomy. After providing written informed consent (in presence of an Independent Witness, if applicable), patients will receive an induction therapy consisting of 12 weekly intravesical instillations of ONCOFID-P-B (induction phase). Patients with residual CIS at the end of induction treatment are eligible to enter a re-induction course of therapy (reinduction phase). Patients with stable disease by Investigator assessment defined as neither increased or decreased in extent or severity compared to baseline, are not eligible for re-induction therapy. Patients who achieve a complete resonde (CR) at the end of the induction or re-induction phase enter in the maintenance phase and receive monthly intravesical instillations of ONCOFID-P-B for an additional 12 monsthe or untile recurrence of CIS/HG Ta-T1 or progression to MIBC or extravesical disease. Patients who do not achieve a CR at the end of induction or re-induction phase, will discontinue investigational treatement and are followed up until month 48 from induction or re-induction start, or until a new antitumor therapy is initiated, wichever occurs first. Tumor response is evaluated by cystoscopy, cytology and biopsy at the end of the induction and re-induction phases and at Safety Follow Up Visit (SFUV). During the maintenance/follow-up period, tumorresponse is evaluated by cystoscopy and cytology every 3 months for up to 24 months from induction or re-induction start, and then every 6 months for an additional 2 years (long-term follow-up). Tumor biopsies are performed in case of of positive cystoscopy and/or cytology. Random biopsies are to be performed at 6, 12 and 18 months after the end of the induction or re-induction phase in responding patients (i.e. at 9, 15 and 21 months after induction or re-induction start.
