Educational Website for Colorectal Cancer
Walla Walla, Washington
This phase III trial evaluates whether a web-based intervention called Current Together after Cancer (CTAC) works to increase the number of patients with surgically removed (resected) colorectal cancer who receive surveillance care that aligns with current guidelines (guideline-concordant). Surveillance care after resection of colorectal cancer is critical to detect potentially curable return of disease (recurrence), yet up to 60% of colorectal cancer survivors fail to receive surveillance. This may be due to a lack of knowledge about the purpose of surveillance care and the risks of cancer recurrence, or a lack of confidence for managing surveillance care. The CTAC intervention is an online education intervention designed to improve patients' knowledge about surveillance and their self-efficacy for managing surveillance, and to promote effective communication with supporters and supporter engagement in patients' surveillance in a way that is aligned with each patient's preferences. By increasing a patient's knowledge, self-efficacy, and satisfaction with their supporter's engagement in their care, the CTAC intervention may increase the number of patients who receive guideline-concordant surveillance care after resection of colorectal cancer.

Trophic Feeding for Sepsis Prevention
Tacoma, Washington
Study Hypothesis/Question In infants born very preterm, advancing enteral feeds after 24 hours from birth (limited trophic feeds) versus after 72 hours (extended trophic feeds) reduces the risk of all-cause late onset sepsis (LOS) without increasing the risk of other adverse outcomes.
Study Design Type This is a multi-center, open-label, parallel-group, individual randomized controlled trial comparing two different trophic feeding regimens in preterm infants born between 25w0d and 31w6d. These infants will be randomly assigned to either the intervention group, receiving limited trophic feeding (20 to 25 mL/kg/day for one day) or the control group, receiving extended trophic feeding (20 to 25 mL/kg/day for three days) prior to advancing enteral feeds until full feeding volume (140 mL/kg/day) is achieved.
Eligibility Criteria Preterm infants with gestational ages between 25 0/7 and 31 6/7 weeks and a birthweight of \<1500 grams who are admitted to six participating neonatal units will be eligible for inclusion. Infants with \<5th percentile for weight at birth, vasopressor use within first 24 hours of life major congenital/genetic anomalies affecting enteral feeding, growth, or mortality, and those with a terminal illness in which decisions to withhold or limit support have been made will be excluded. Infants of parents or legal guardians who are unable to provide consent within 36 hours of birth will also be excluded.
Study Intervention/Methods Written parental informed consent will be obtained prenatally or within the first 36 hours of birth. Infants will be randomized to receive limited trophic feeds of 24 to 36 hours or extended trophic feeds for 72 hours prior to the advancement of enteral feeds. Infants will be fed parent's own milk (POM) with donor human milk as the alternative if POM is unavailable.
Primary Outcome Late-onset sepsis, defined as positive blood, urine, and/or cerebrospinal fluid (CSF) cultures in the presence of compatible clinical signs of sepsis, occurring after postnatal day 3 and before hospital discharge, and treated with antibiotics for 5 days or more.
Secondary Outcome(s) The trial will assess various secondary outcomes including length of hospital stay, all-cause in-hospital mortality, duration of IV fluids and central line utilization, necrotizing enterocolitis (Bell's stage IIa or higher), severe intraventricular hemorrhage (grade III or IV either unilaterally or bilaterally), bronchopulmonary dysplasia (oxygen requirement or positive pressure ventilation at 36 weeks corrected gestational age), or retinopathy of prematurity requiring intervention. Additionally, growth metrics throughout hospitalization will be evaluated using change in weight, length, and head circumference z-scores from birth to 36 weeks' corrected gestational age between infants in the limited and extended trophic feeding groups.

MAP
Seattle, Washington
MAP will be a multisite phase II/III 1:1 randomized controlled trial (RCT) of long acting metformin (reduced mass Glucophage XR) vs. matching placebo in 326 men and women with early and late aMCI, without diabetes, not treated with metformin, overweight or obese, aged 55 years to 90 years. The RCT will last 18 months and have 4 visits: baseline, 6-months, 12-months, and 18-months. The RCT will be preceded by a screening phase followed by randomization and a titration period in which drug/placebo will be titrated from 500 mg a day (one tablet) to 2,000 mg a day (4 tablets), in increments of 500 mg (one tablet) every 10 days. Participants will remain in the RCT on the tolerated dose, and included in analyses on an intent to treat basis. We expect the attrition rate to be 10%/year. Neuropsychological battery, clinical interviews, physical exam, and phlebotomy will be conducted at baseline and every 6 months. Brain MRI will be conducted in approximately half of the participants (186) twice, at baseline, and after the last study visit at month 18. We will also conduct brain amyloid Positron Emission Tomography (PET) using 18F-Florbetaben, and tau PET using 18F-MK6240 in half of the participants at baseline and end of the RCT.
The primary clinical outcome of the study will be changes in the Free and Cued Selective Reminding Test. The secondary endpoints are 1) changes in global cognitive performance, measured with the Alzheimer's Disease Cooperative Study Preclinical Alzheimer Cognitive Composite (ADCS-PACC); 2) changes in neurodegeneration, ascertained as cortical thickness in areas affected by AD on brain MRI; 3) changes in cerebrovascular disease, ascertained as white matter hyperintensities (WMH) volume on brain MRI; 4) Changes in whole brain amyloid ß (Aß) SUVR and in incident amyloid positivity; 5) Changes in tau SUVR in a composite brain region comprising medial and inferolateral temporal cortex; 6) Changes in plasma AD biomarkers.
The data coordinating center and Imaging Core is located at John Hopkins University. The PET coordinating center is located at UC-Berkeley. The Clinical Coordinating and Monitoring Center and the central laboratory will be located at Columbia. The Research pharmacy function will be shared by the University of Rochester, which will dispense randomization kits, and the University of Iowa, which will receive bulk metformin and identical matching placebo from EMD Serono.

"I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across trials in Washington 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length in Washington is 12 months.
How do I participate in a study as a "healthy volunteer"?
Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility in Washington several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.
What does the "phase" of a clinical trial mean?
The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.
Do I need to be insured to participate in a medical study in Washington?
Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.
