The primary objective of this study is to compare the progression-free survival (PFS) between sacituzumab govitecan-hziy (SG) versus treatment of physician's choice (TPC) in participants with previously untreated, locally advanced, inoperable or metastatic triple-negative breast cancer whose tumors do not express programmed cell death ligand 1 (PD-L1) or in participants previously treated with anti-programmed cell death (ligand or protein) 1 (Anti-PD-(L)1) Agents in the early setting whose tumors do express PD-L1.

In the United State, there are millions of US teens who are not vaccinated against the human papillomavirus (HPV) putting them at risk of getting HPV-related cancers. Although there are clinical guidelines recommending the HPV vaccine and interventions encouraging parents to vaccinate their children to prevent HPV-related cancers, the vaccination rate for teens remains low according to a 2018 national survey. Survey data shows that HPV vaccine complete series coverage for teens aged 13-15 years was 50%, far below the 80% target of Healthy People 2020. Receiving a strong provider recommendation is the most powerful strategy for improving HPV vaccine rates. Yet, little is known about how to include provider recommendations and other important factors into an intervention to improve the HPV vaccination rates. Studies show there are provider, patient and system-level barriers in the initiation and completion of HPV vaccine series among 9-12 years old children. Barriers to the HPV vaccine also differ across demographic subgroups, communities, and clinics. Interventions that address only one component are not responsive to site barriers and as effective as one that addresses multiple components and site-specific barriers. This study uses a 3-arm cluster randomized controlled trial (RCT) to compare three implementation strategies to improve provider recommendations on the HPV vaccine. Two of the implementation strategies (local-tailored and prescribed strategy) utilize a multilevel approach. The three implementation strategies of interest are (1) a "local-tailored" implementation strategy, co-designed with local care teams to address local barriers and contexts (2) A "prescribed" strategy, most commonly used by health systems, that involves pre-specified interventions addressing pre-selected vaccination barriers and (3) usual standard of care where there are no research-led activities. We will use surveys, interviews, and electronic health records to evaluate the three implementation strategies and their impact on improving HPV vaccination rates. The study surveys and interviews will include pediatric providers, nurses, administrators, staff members, and parents of HPV vaccine-eligible children (9-12 years old). Successful implementation will be defined as improvement in HPV vaccination rates (primary outcome), strengthening provider recommendation (secondary outcome), and the cost-effectiveness of the implementation strategy.

The primary objectives of this study are to evaluate the safety of single IV doses of UX701 in patients with Wilson disease, to select the UX701 dose with the best benefit/risk profile based on the totality of safety and efficacy data and to evaluate the effect of UX701 on copper regulation.

This clinical trial evaluates how well two surgical procedures (bilateral salpingectomy and bilateral salpingo-oophorectomy) work in reducing the risk of ovarian cancer for individuals with BRCA1 mutations. Bilateral salpingectomy involves the surgical removal of fallopian tubes, and bilateral salpingo-oophorectomy involves the surgical removal of both the fallopian tubes and ovaries. This study may help doctors determine if the two surgical procedures are nearly the same for ovarian cancer risk reduction for women with BRCA1 mutations. Read Less

VETERANS ONLY. Chronic low back pain (cLBP) is common. Most Americans will have at least one episode of low back pain in their lifetimes. Approximately 50% of all US Veterans have chronic pain, and CLBP is the most common type of pain in this population. This study will use a sequential randomized, pragmatic, 2-step comparative effectiveness study design. The main goal is to identify the best approach for treating cLBP using commonly recommended non-surgical and non-pharmacological options. The first step compares continued care and active monitoring (CCAM) to internet-based pain self-management (Pain EASE) and an enhanced physical therapy intervention that combines Pain EASE with tailored exercise and physical activity. Patients who do not have a significant decrease in pain interference (a functional outcome) in Step 1 and those desiring additional treatment will be randomized in Step 2 to yoga, spinal manipulation therapy (SMT), or therapist-delivered cognitive behavioral therapy (CBT). Participants proceeding to randomization in Step 2 will be allowed to exclude up to one of the three Step 2 treatments based on their preferences. The investigators' primary hypothesis for the first treatment step is that an enhanced physical therapy intervention that combines pain self-management education with a tailored exercise program will reduce pain interference greater than internet-based pain self-management alone or CCAM in Veterans with cLBP. The primary outcome is change in pain interference at 3 months, measured using the Brief Pain Inventory (BPI) pain interference subscale. Study participants will be followed for one year after initiation of their final study treatments to assess the durability of treatment effects. The study plans to randomize 2529 patients across 20 centers. Read Less

This trial studies how well iohexol works in helping doctors calculate the dose of carboplatin given to patients with cancer. Drugs used in chemotherapy, such as carboplatin, 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. Understanding how to best calculate the dose of carboplatin given to patients with cancer may help doctors learn how to improve the use of carboplatin in the future. Read Less

The Study is designed to collect information about adverse events that occur in children undergoing anesthesia in participating hospitals. Demographic information will be collected on all anesthetics. An analysis of each adverse event will be performed and entered into the database. From this information we will devise strategies to prevent these adverse events. Read Less

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare immune system disorder that causes asthma, an excessive number of eosinophils (a type of white blood cell) in the blood, and the inflammation of blood vessels, or vasculitis. In order to properly treat EGPA, it is critical that the level of disease activity can be determined over the course of the disease. The purpose of this study is to determine new biological markers, or biomarkers, that may be used to assess the severity of this disease in people with EGPA. Read Less

The purpose of this trial is to assess the safety and relative efficacy of CVXGA (CVXGA50), a KP.2 containing vaccine, compared to COMIRNATY® (COVID-19 Vaccine, mRNA; 2024-2025 Formula), a currently approved COVID-19 vaccine in the prevention of symptomatic, RT-PCR-confirmed SARS-CoV-2 infection. The trial will enroll up to 10016 healthy participants. Read Less

This trial will evaluate the impact of a multicomponent program (TBI Rehabilitation and Activation in Veterans; TRAIN-Vets) on improving cognitive function over an 8-month trial period in older Veterans with traumatic brain injury (TBI). Older Veterans with a history of TBI and subjective cognitive complaints will be enrolled and randomly assign to either the TRAIN-Vets intervention (consisting of aquatic-based exercise training, cognitive training, and lifestyle coaching) or the Health Education Control, where they will receive educational materials about brain health and healthy lifestyles.
