NCT05050084
This phase III trial uses the Decipher risk score to guide therapy selection. Decipher score is based on the activity of 22 genes in prostate tumor and may predict how likely it is for recurrent prostate cancer to spread (metastasize) to other parts of the body. Decipher score in this study is used for patient selection and the two variations of treatment to be studied: intensification for higher Decipher score or de-intensification for low Decipher score. Patients with higher Decipher risk score will be assigned to the part of the study that compares the use of 6 months of the usual treatment (hormone therapy and radiation treatment) to the use of darolutamide plus the usual treatment (intensification). The purpose of this section of the study is to determine whether the additional drug can reduce the chance of cancer coming back and spreading in patients with higher Decipher score. The addition of darolutamide to the usual treatment may better control the cancer and prevent it from spreading. Alternatively, patients with low Decipher risk score will be assigned to the part of the study that compares the use of radiation treatment alone (de-intensification) to the usual approach (6 months of hormone therapy plus radiation). The purpose of this part of the study is to determine if radiation treatment alone is as effective compared to the usual treatment without affecting the chance of tumor coming back in patients with low Decipher score prostate cancer. Radiation therapy uses high energy to kill tumor cells and reduce the tumor size. Hormone therapy drugs such as darolutamide suppress or block the production or action of male hormones that play role in prostate cancer development. Effect of radiation treatment alone in patients with low Decipher score prostate cancer could be the same as the usual approach in stabilizing prostate cancer and preventing it from spreading, while avoiding the side effects associated with hormonal therapy.
NCT00335816
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as fluorouracil, oxaliplatin, and leucovorin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Fluorouracil may also make tumor cells more sensitive to radiation therapy. Leucovorin calcium may protect normal cells from the side effects of chemotherapy, and it may help fluorouracil work better by making tumor cells more sensitive to the drug. Giving radiation therapy together with chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This phase II trial is studying how well giving radiation therapy together with fluorouracil with or without combination therapy works in treating patients who are undergoing surgery for stage II or stage III rectal cancer.
NCT05624996
This phase III trial compares the effect of adding stereotactic body radiation therapy (SBRT) to the usual treatment (conventional image guided radiation therapy \[IGRT\] and chemotherapy followed by immunotherapy with durvalumab or targeted therapy with osimertinib) versus the usual treatment alone in treating patients with non-small cell lung cancer that has spread to nearby tissue or lymph nodes (locally advanced) and cannot be treated by surgery (inoperable). SBRT uses special equipment to position a patient and deliver radiation therapy to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. IGRT is a type of radiation therapy that creates a picture of the tumor to help guide the radiation beam during therapy, making it more accurate and causing less damage to healthy tissue. Usual chemotherapy used in this trial consists of combinations of the following drugs: cisplatin, carboplatin, paclitaxel, nab-paclitaxel, pemetrexed, and etoposide. Cisplatin and carboplatin are in a class of medications known as platinum-containing compounds. Cisplatin works by killing, stopping, or slowing the growth of tumor cells. Carboplatin 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 as well. Paclitaxel is in a class of medications called antimicrotubule agents. It works by stopping the growth and spread of tumor cells. Nab-paclitaxel is an albumin-stabilized nanoparticle formulation of paclitaxel which may have fewer side effects and work better than other forms of paclitaxel. Pemetrexed is in a class of medications called antifolate antineoplastic agents. It works by blocking the action of a certain substance in the body that may help tumor cells multiply. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and deoxyribonucleic acid (DNA) repair and may kill tumor cells. Immunotherapy with durvalumab can induce changes in the body's immune system and can interfere with the ability of tumor cells to grow and spread. Osimertinib is in a class of medications called kinase inhibitors. It works by blocking the action of a protein called EGFR that signals cancer cells to multiply. This helps slow or stop the spread of tumor cells. Adding SBRT to the usual treatment of IGRT with chemotherapy and immunotherapy may be more effective at treating patients with locally-advanced non-small cell lung cancer than giving the usual treatment alone.
NCT04998851
This study will evaluate the pharmacokinetics of ocrelizumab in the breastmilk of lactating women with clinically isolated syndrome (CIS) or multiple sclerosis (MS) \[in line with the locally approved indications\] treated with ocrelizumab, by assessing the concentration of ocrelizumab in mature breastmilk, as well as the corresponding exposure and pharmacodynamic effects (blood B cell levels) in the infants.
NCT05924672
This phase II trial studies how well prostate-specific membrane antigen (PSMA) positron emission tomography (PET) scans (in combination with bone scans) work in selecting patients for Ra-223 radiation therapy that have castration-resistant prostate cancer that has spread from where it first started (primary site) to the bones (bone metastasis). Ra-223 is a type of therapy that emits radiation. Radiation gives off energy which can kill tumor cells and other cells that may support the tumor cells. Ra-223 is given by infusion into the veins, where it is absorbed by the bones. PSMA PET is a type of scan used to detect prostate cancer tumors. PSMA is a radioactive tracer that binds to a specific protein that is found on prostate tumor cells. The PSMA tracer shows the areas on the PET scan where tumor cells are active. A PET scan uses a special camera to detect the energy given off from radioactive tracers (such as PSMA) to make detailed pictures of areas where the tracer accumulates in the body. The PET scan is often combined with a magnetic resonance imaging (MRI) or computed tomography (CT) scan, which helps to map the locations where PSMA has accumulated. PSMA PET scans may be able to select patients that will benefit the most from Ra-223 treatment.
NCT05877729
The goal of this randomized clinical trial is to test the effect of a technology-based intervention with an Adaptive Treatment Strategy (ATS) among youth living with HIV (YLWH) (18-29 years old). This piloted and protocolized intervention combines: (1) brief weekly sessions with a counselor via a video-chat platform (video-counseling) to discuss mental health (MH), substance use (SU), HIV care engagement, and other barriers to care; and (2) a mobile health application (app) to address barriers such as ART forgetfulness and social isolation. Individuals who are not virologically suppressed will be randomized to video-counseling+app or standard of care (SOC). Through this study, the investigators will be able to: Aim 1: Test the efficacy of video-counseling+app vs SOC on virologic suppression in YLWH.The investigators will compare HIV virologic suppression of those randomized to the intervention vs control arms at 16 weeks via an RCT. Aim 2: Assess the impact of video-counseling+app vs SOC on MH and SU in YLWH. The investigators will evaluate the MH and SU differences between the intervention vs control arms at 16 weeks via an RCT. Aim 3: Explore an ATS to individualize the intervention by assigning the: 1. virologic "non-responders" in the intervention arm to intensified video-counseling+app for 16 more weeks, 2. virologic "responders" in the intervention arm to continue only app use for 16 more weeks. Researchers will compare the characteristics of virologic responders and non-responders to the intervention, individualization of the intervention based on these variables, and linkage to MH and SU treatment services among those in need to see if delivery of care is enhanced and impact on virologic suppression.
NCT05569759

LCN Cohort Study involves multiple institutions and an anticipated 1200 participants. Enrolled participants will have study visits every 6 months (180 days), with opportunities to complete specific visit components via telehealth or remotely. Visits will include collection of questionnaire data and the in-person visits will include questionnaires, physical exams, imaging, and sample collection.
NCT05053152
This phase II trial compares the usual treatment of radiation therapy alone to using the study drug, relugolix, plus the usual radiation therapy in patients with castration-sensitive prostate cancer that has spread to limited other parts of the body (oligometastatic). Relugolix is in a class of medications called gonadotropin-releasing hormone (GnRH) receptor antagonists. It works by decreasing the amount of testosterone (a male hormone) produced by the body. It may stop the growth of cancer cells that need testosterone to grow. Radiation therapy uses high-energy x rays or protons to kill tumor cells. The addition of relugolix to the radiation may reduce the chance of oligometastatic prostate cancer spreading further.
NCT06577090
This is a proof-of-concept study to assess the safety and efficacy of Nimacimab Injection compared to an active and placebo injection control.
NCT00602667
RATIONALE: In this study a combination of anti-cancer drugs (chemotherapy) is used to treat brain tumors in young children. Using chemotherapy gives the brain more time to develop before radiation is given. The chemotherapy in this study includes the drug methotrexate. This drug was an important part of the two clinical trials which resulted in the best survival results for children less than 3 years of age with medulloblastoma. Most patients treated on this trial will also receive radiation which is carefully targeted to the area of the tumor. This type of radiation (focal conformal or proton beam radiotherapy) may result in fewer problems with thinking and learning than radiation to the whole brain and spinal cord. PURPOSE: This clinical trial is studying how well giving combination chemotherapy together with radiation therapy works in treating young patients with newly diagnosed central nervous system tumors.
NCT07337655
This protocol describes a seamless Phase II/III, randomized, double-blind clinical trial evaluating the efficacy and safety of daily low-dose aspirin (81 mg) plus lansoprazole (30 mg) in pregnant individuals at high risk for preterm birth when compared to existing standard of care, identified through biomarker-enriched screening. Participants will be enrolled between 12-16+6 weeks' gestation and followed through delivery and postpartum. The primary objective is to determine whether the investigational combination reduces the incidence of preterm birth before 37 weeks of gestation compared with placebo.
NCT05614739
The main purpose of this study is to learn more about the safety, side effects, and effectiveness of LOXO-435 by itself or when it is combined with other standard medicines that treat cancer. LOXO-435 may be used to treat cancer of the cells that line the urinary system and other solid tumor cancers that have a change in a particular gene (known as the FGFR3 gene). Participation could last up to 30 months (2.5 years) and possibly longer if the disease does not get worse.
NCT07336940
The goal of this clinical trial is to learn about the safety and tolerability of ENV-294 in adults with moderate to severe atopic dermatitis. It may also learn about the changes ENV-294 may have on the severity of atopic dermatitis symptoms. The main questions it will answer are: * Is ENV-294 safe and well tolerated in adults with moderate to severe atopic dermatitis? * Is there an impact on the severity of atopic dermatitis symptoms when participants take ENV-294? Researchers will review the atopic dermatitis present at the beginning of the study against the atopic dermatitis present at the end of the study. Participants will: * Take drug ENV-294 once every day for 28 days * Visit the clinic weekly for 4 weeks for checkups and tests * Keep a diary of their symptoms and when they took their study drug ENV-294

NCT03148418
This is an open-label, multicenter, non-randomized extension and long-term observational study. Participants receiving atezolizumab monotherapy or atezolizumab combined with other agent(s) or comparator agent(s) in a Genentech or Roche-sponsored study (the parent study) and who continue to receive study treatment at the time of the parent-study closure and do not have access to the study treatment locally are eligible for continued treatment in the extension study. Dosing regimen for a given participant and indication will be the same or equivalent to the respective parent study protocol. Study treatment in the extension study can continue until disease progression or beyond if the patient continues to derive clinical benefit as judged by the investigator and if allowed by the parent study or local prescribing information until death; withdrawal of study consent; unacceptable toxicity; pregnancy; patient non-compliance; or study termination by the Sponsor, whichever occurs first.
NCT02264613
