The purpose of this study is to evaluate the long-term safety and efficacy of pembrolizumab (MK-3475) in participants from previous Merck pembrolizumab-based parent studies who transition into this extension study. This study will consist of three phases: 1) First Course Phase, 2) Survival Follow-up Phase or 3) Second Course Phase. Each participant will transition to this extension study in one of the following three phases, depending on the study phase they were in at the completion of the parent study. Participants who were in the First Course Phase of study treatment with pembrolizumab or lenvatinib in their parent study will enter the First Course Phase of this study and complete up to 35 doses or more every 3 weeks (Q3W) or 17 doses or more every 6 weeks (Q6W) of study treatment with pembrolizumab or a pembrolizumab-based combination or lenvatinib according to arm assignment. Participants who were in the Follow-up Phase in the parent study (post-treatment or Survival Follow-up Phase) will enter the Survival Follow-up Phase of this study. Participants who were in the Second Course Phase in their parent study will enter Second Course Phase of this study and complete up to 17 doses Q3W or 8 doses Q6W of study treatment with pembrolizumab or a pembrolizumab-based combination according to arm assignment. Any participant originating from a parent trial where crossover to pembrolizumab was permitted upon disease progression may be eligible for 35 doses as Q3W or 17 doses Q6W of pembrolizumab (approximately 2 years), if they progress while on the control arm and pembrolizumab is approved for the indication in the country where the potential eligible crossover participant is being evaluated.

The Pompe Registry is a global, multicenter, international, longitudinal, observational, and voluntary program for patients with Pompe disease, designed to track the disease's natural history and outcomes in patients, both treated and not. Data from the Registry are also used to fulfill various global regulatory commitments, to support product development/reimbursement, and for other research and non-research related purposes. The objectives of the Registry are: - To enhance understanding of the variability, progression, identification, and natural history of Pompe disease, with the ultimate goal of better guiding and assessing therapeutic intervention. - To assist the Pompe medical community with the development of recommendations for monitoring patients, and to provide reports on patient outcomes, to optimize patient care. - To characterize the Pompe disease population. - To evaluate the long-term effectiveness of alglucosidase alfa.

The primary objectives of this study are twofold: 1) to detect and determine the level of symptoms, functional disability, and changes in quality of life that breast cancer patients experience from changes in their arms during and after treatment for breast cancer by collecting patient reported outcome measures, objective measurements, and clinical information in a prospectively maintained database and 2) to improve breast cancer-related lymphedema outcomes by early detection using objective measurements and symptoms assessments and assess these outcomes by maintaining the data in a database in order to contribute to the literature. The secondary aim of this study is to assess extracellular fluid content in the upper extremity, breast, and/or trunk of patients treated for breast cancer before, during, and after treatment in order to better understand the role of bioimpedance spectroscopy in lymphedema screening.

Many people living with metastatic breast cancer face challenging symptoms and frequent medical visits. At the same time, conversations about personal goals, values, and preferences for care may not always happen as early or as often as patients and families would like. This multi-site study will test the effectiveness of a five-session palliative care program, designed specifically for people with metastatic breast cancer and their caregivers, to strengthen communication with clinicians about what matters most in their care. The study aims to inform how palliative care services can be delivered in a more timely, personalized, and scalable way for people living with advanced cancers who have long disease trajectories, such as metastatic breast cancer.

The National Liver Cancer Screening Trial is an adaptive randomized phase IV Trial comparing ultrasound-based versus biomarker-based screening in 5500 patients with cirrhosis from any etiology or patients with chronic hepatitis B infection. Eligible patients will be randomized in a 1:1 fashion to Arm A using semi-annual ultrasound and AFP-based screening or Arm B using semi-annual screening using GALAD alone. Randomization will be stratified by sex, enrolling site, Child Pugh class (A vs. B), and HCC etiology (viral vs. non-viral). Patients will be recruited from 15 sites (mix of tertiary care and large community health systems) over a 3-year period, and the primary endpoint of the phase IV trial, reduction in late-stage HCC, will be assessed after 5.5 years.
