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.
NCT04134260
This phase III trial studies whether adding apalutamide to the usual treatment improves outcome in patients with lymph node positive prostate cancer after surgery. Radiation therapy uses high energy x-ray to kill tumor cells and shrink tumors. Androgens, or male sex hormones, can cause the growth of prostate cancer cells. Drugs, such as apalutamide, may help stop or reduce the growth of prostate cancer cell growth by blocking the attachment of androgen to its receptors on cancer cells, a mechanism similar to stopping the entrance of a key into its lock. Adding apalutamide to the usual hormone therapy and radiation therapy after surgery may stabilize prostate cancer and prevent it from spreading and extend time without disease spreading compared to the usual approach.
NCT04088331
To evaluate the AMS 800 Artificial Urinary Sphincter (AUS) in men with primary stress urinary incontinence as measured by pad weight tests.
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.
NCT05569759
This was a Phase 2a, multi-center, placebo-controlled study in which patients with autoimmune hepatitis received zetomipzomib or placebo in addition to standard-of-care for 24 weeks; an optional open-label extension period allowed participants to receive zetomipzomib (KZR-616) for an additional 24 weeks of treatment.

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.
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.
NCT07335601
A Phase 2 double-blind, randomized, placebo-controlled study to evaluate resmetirom in 2 cohorts of subjects with moderate to advanced fibrosis, consistent with stage F2 and F3 fibrosis, who have undergone liver transplant. Cohort 1 will consist of patients who have undergone liver transplant for MASH cirrhosis who developed recurrent MASH. Cohort 2 will consist of subjects who have undergone liver transplant for indications other than MASH cirrhosis who developed de novo MASH.
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.

This is a proof-of-concept study to assess the safety and efficacy of Nimacimab Injection compared to an active and placebo injection control.
NCT03178149
Age-related macular degeneration (AMD) is an eye disease which causes people to lose their sharp central vision over time. Aging damages the macula, which is in the middle of the retina - the light-sensitive part at the back of the eye. There are 2 types of AMD - wet AMD and dry AMD. The advanced stage of dry AMD causes vision loss. This is known as geographic atrophy. AMD makes everyday tasks like reading or driving difficult. ASP7317 is a potential new treatment for people with AMD. ASP7317 are human stem cells which have changed into cells found in the retina. ASP7317 is injected under the macula. It is hoped that ASP7317 will replace some of the damaged cells in the macula and improve vision for people with dry AMD. Before ASP7317 is available as a treatment, the researchers need to check its safety and how well it is tolerated. They will also check for signs of improved vision. People taking part in this study will be older people who have geographic atrophy caused by dry AMD. This is an open-label study. This means that people in this study and clinic staff will know that people will receive ASP7317. There will be 3 doses of ASP7317. These are low, medium and high numbers of cells. ASP7317 will be injected under the macula after the person is given either a local or a general anesthetic. To prevent the body from rejecting the cells, people will take tablets of tacrolimus a few days before receiving ASP7317 for up to a few weeks afterwards. Other medicines will be taken during this time to stop infections. There will be 2 groups in the study. Group 1 will be people with severe vision loss and Group 2 will be people with moderate vision loss. There will be different small groups of people within Group 1 and Group 2, with each small group receiving 1 of the 3 doses of ASP7317. Different small groups of people within Group 1 and Group 2 will receive lower to higher doses of ASP7317. Each small group will only receive 1 dose. Group 1 will start treatment first. At each dose, a medical expert panel will check the results of the first person in the group to decide if the rest of the group will receive the same dose. Then, the panel will decide if more people may receive the same dose or if the next group may receive the next highest dose. The panel will use the results from the lower dose of Group 1 to decide when Group 2 starts treatment (also at the lower dose). The panel will also use the results of the middle and higher doses in Group 1 to decide when and how many people in Group 2 can receive these doses. During the study, people will visit the clinic several times for up to 12 months (1 year). During all visits, the study doctors will check for any medical problems after receiving ASP7317. Vital signs will be checked a few days before treatment with ASP7317 and up to about a month afterwards. Vital signs include blood pressure, pulse, and temperature. At some visits, the study doctors will also take blood samples for blood tests. At most visits, people will have eye tests and have different images, scans, and measurements taken. This could be for the affected eye or both eyes, depending on the test. People can visit the clinic extra times, if needed.

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.
