Researchers are looking for new ways to treat certain types of advanced gastrointestinal (GI) cancers. The study medicine raludotatug deruxtecan (also called MK-5909, R-DXd, or DS-6000a) is a type of medicine called an antibody-drug conjugate (ADC). An ADC attaches to a protein on cancer cells and delivers treatment to destroy those cells. The main goal of this study is to learn if the cancer responds to treatment (gets smaller or goes away).

This research study aims to find out the effect of REPOSE, a patient navigation intervention, on the receipt of equitable care among children with a broad range of socioeconomic and rural/urban status with Sleep Disordered Breathing (SDB). In the REPOSE intervention, a centralized patient navigator a) identifies and addresses dynamic individual barriers, b) provides resources and social support for parent-child dyads, and c) facilitates bidirectional SDB care coordination between clinical teams and parents to achieve evidence-based care. This study will evaluate the effects of the REPOSE intervention on SDB care delivery and clinical process outcomes for children with a broad range of socioeconomic and rural/urban status by reducing barriers and increasing self-efficacy among parents.

Idiopathic Hypersomnia (IH) is a condition where people feel extremely sleepy during the day, especially in the morning, even if they sleep a lot at night. They may have trouble waking up in the morning, no matter how much they sleep (sometimes more than 11 hours per day), and they can't help feeling tired, even after taking daytime naps. Because of this sleepiness, they may have trouble focusing, thinking clearly, or keeping up with daily activities. They may also have symptoms like dizziness or feeling lightheaded. Orexin is a chemical made in the brain that helps keep a person awake and alert. TAK-360 acts like orexin. Previous studies have shown that medicines that act like orexin may keep people awake. The main aim of this study is to learn how safe TAK-360 is and how well adults with IH tolerate it. Researchers also want to find out if TAK-360 can help people with IH stay awake and how much TAK-360 is needed to do that. Participants will be randomly (by chance, like drawing names from a hat) chosen to receive either TAK-360 or a placebo. The placebo looks just like TAK-360 but does not have any medicine in it. Using a placebo helps researchers learn about the real effect of the treatment.

Adults 18 years of age and older or above legal age with lung fibrosis related to systemic autoimmune rheumatic disease can participate in this study. People can only take part if they show no improvement in lung function after standard treatment with immunosuppressant medicine. The main purpose of this study is to find out how a medicine called nerandomilast affects the lungs in people with systemic autoimmune rheumatic disease. Participants are put into 2 groups randomly, which means by chance. One group takes nerandomilast tablets and the other group takes placebo tablets. Placebo tablets look like nerandomilast tablets but do not contain any medicine. Participants take a tablet 2 times a day for at least 26 weeks and up to 1 year. Participants continue immunosuppressant treatment for their underlying rheumatic disease. Participants are in the study for about 7.5 to 13 months depending on when they join the study. During this time, they visit the study site about 9 to 10 times. At study visits, participants have lung function tests. At select visits, chest imaging is performed. Participants fill in questionnaires about their symptoms and quality of life. The results between the 2 groups are compared to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.

The purpose of this phase 1a/b trial is to find out what amount of exercise would be best to use for preventing recurrence of colorectal polyps. It involves following one of four different amounts of exercise regimens on a treadmill for 26 weeks. A treadmill will be placed in each study participant's home for the duration of the study. The exercise regimen will be personalized for each participant and monitored remotely by exercise personnel. The in-person study visits occur during the usual standard of care endoscopy exam and during a follow-up exam that is 26 weeks later. Small rectal tissue biopsies, about the size of a grain of rice, will be taken before and after 26 weeks of exercise. The study visits also involve questionnaires, a stool sample, and a blood sample. This study will inform the design of larger, future trials to investigate whether or not recurrence of polyps can be achieved with exercise.

Purpose: Aim 1: Quantify soft tissue complications and infections of service members with transtibial amputations treated with OPRA OI and compare them to transfemoral OI service members. Aim 2: Compare the validated domains, such as functional, quality of life and pain scores, from the preoperative baseline to follow-up visits to determine if persons with transtibial amputations treated with OPRA osseointegrated prostheses demonstrate statistically significant and clinically relevant improvements. Aim 3: Compare physical performance measures preoperatively to follow-up visits for persons with transtibial amputations treated with OPRA osseointegrated prostheses to quantify statistically significant and clinically relevant improvements. Aim 4: Quantify the biomechanical loading and bone quality changes that are directly associated with patient reported outcomes for persons with transtibial amputations treated with OPRA osseointegration. Aim 5: Compare outcome measures between persons with traditional socket prostheses (patients as self-controls) and OPRA OI devices as well as a comparison between persons with transtibial OI and transfemoral OI. Subject Population: Male and female military health care beneficiaries age 22 to 65 years old presenting with a Transtibial limb loss. Study Design: This is a 4-year, prospective cohort FDA pivotal study involving off-label use of the OPRA OI implant in persons with transtibial amputation. Procedures: SURGICAL PROCEDURES: Surgery Stage I: The distal part of the tibia is exposed, preferably using existing incisions, to produce an appropriate fasciocutaneous flap. By the use of fluoroscopy and guiding devices the correct position of the fixture in the medullary canal is found. The canal is reamed step by step to a proper diameter to facilitate insertion of the implant. If the bone quality is poor, as determined by the operating surgeon, autologous bone graft from the iliac crest and/or the medullary canal is used. The fixture is then implanted into the intramedullary canal. Careful surgical technique is essential not to damage the tissue and to achieve osseointegration. A central screw, healing cylinder, and healing bolt are inserted. A myodesis is performed, and the wound is closed using suture. The sutures are removed 2-3 weeks postoperatively. When the skin is completely healed the Patient's conventional socket prosthesis could, in some instances, be used. Surgery Stage II (3-5 months after Stage I): The tibia is exposed via the incision from the Stage I-Surgery. The healing cylinder is removed and the tissues are trimmed in a way that the distal end of the bone protrudes a few millimeters. The skin will be attached directly to it. The endosteal canal is reamed to facilitate placement of the abutment. The skin in the abutment area is then trimmed to a diameter equal to the protruding end of the tibia. This is done to remove the subcutaneous fat and facilitate healing of the dermal layer to the distal end of the bone. The subcutaneous tissue is affixed to the periosteum using absorbable suture to prevent skin movement. A 8mm punch biopsy tool is used to create a circular hole in the skin precisely over the residual tibial canal. The remaining portion of the fasciocutaneous flap is sutured into position. A bolster dressing is placed and routine postoperative wound care is performed by daily dressing changes. Sutures are removed 2-3 weeks postoperatively. CLINICAL PROCEDURES A pre-study visit will be conducted up to 6 months prior to Surgery Stage I. Postoperative visits will occur 2-3 weeks after each surgery. Additional follow-up visits will occur 6, 12, 24, 36, 48 and 60 months post-Surgery Stage II. It is standard of care to follow patients postoperatively from time to time to ensure the wound(s) is /are healing, surveil for complications, and ensure rehabilitation is progressing. That said, the sole reason for engaging in the Clinical Follow-Up Procedures is for the purpose of conducting research under this particular protocol. Additional visits may occur including x-rays at the discretion of the clinical investigator in order to monitor the participants medical status/bone healing. RESEARCH PROCEDURES Timepoints: Baseline, Post-Op Stage II, 6 months, 12 months, 24 months, 36 months, 48 months, and 60 months The patients will be assessed before and after the surgery regularly. Both performance and safety data will be recorded on specially designed electronic Case Report Forms (eCRFs). Clinical and radiological assessments are performed preoperatively (in connection with the surgical procedures.

This phase III trial compares standard therapy given after surgery (adjuvant) to standard therapy given before and after surgery (perioperative) in treating patients with stage II-IIIB non-small cell lung cancer (NSCLC) that can be removed by surgery (resectable). The usual approach for patients with resectable NSCLC is chemotherapy and/or immunotherapy before surgery, after surgery, or both before and after surgery. This study is being done to find out which approach is better at treating patients with lung cancer. Treatment will be administered according to the current standard of care at the time of enrollment. Chemotherapy options may include cisplatin, carboplatin, pemetrexed, gemcitabine, docetaxel, and vinorelbine at standard doses according to the treating physician. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. 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. Pemetrexed is in a class of medications called antifolate antineoplastic agents. It works by stopping cells from using folic acid to make deoxyribonucleic acid (DNA) and may kill tumor cells. Gemcitabine is a chemotherapy drug that blocks the cells from making DNA and may kill tumor cells. Docetaxel is in a class of medications called taxanes. It stops tumor cells from growing and dividing and may kill them. Other chemotherapy drugs, such as vinorelbine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading . Immunotherapy with monoclonal antibodies, such as nivolumab, pembrolizumab, and atezolizumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Starting treatment with chemotherapy and immunotherapy prior to surgery and continuing treatment after surgery may be a more effective treatment option than adjuvant therapy alone in patients with stage II-IIIB resectable NSCLC.
