Learn More About PowerTrophic Feeding for Sepsis Prevention
Seattle, 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.

Chemotherapy + Immunotherapy for Acute Lymphoblastic Leukemia
Seattle, Washington
This randomized phase III trial studies combination chemotherapy with blinatumomab to see how well it works compared to induction chemotherapy alone in treating patients with newly diagnosed breakpoint cluster region (BCR)-c-abl oncogene 1, non-receptor tyrosine kinase (ABL)-negative B lineage acute lymphoblastic leukemia. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as blinatumomab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. It is not yet known whether combination chemotherapy is more effective with or without blinatumomab in treating newly diagnosed acute lymphoblastic leukemia.

Dronabinol Effects on THC Metabolism During Pregnancy
Seattle, Washington
Cannabis use is prevalent among pregnant women, but the effects of use on both the developing fetus and pregnant woman are unknown. Importantly, drug exposure could be influenced by the impact of pregnancy-associated hormones on the metabolism of tetrahydrocannabinol (THC), the main psychoactive component of cannabis. The goal of this study is to determine whether cortisol and estradiol - hormones that rise dramatically during pregnancy - increase the clearance of dronabinol (THC) in reproductive age women to simulate the pregnant state. The collected data will then be used to predict the time course and magnitude of changes in THC metabolism in pregnant women, particularly with gradually increasing estradiol and cortisol concentrations that evolve over the course of pregnancy. The overall objective of this study is to better understand the effects of THC use during pregnancy on the health of the pregnant woman and developing fetus.

Pimavanserin vs. Quetiapine for Psychosis in Parkinson's Disease
Seattle, Washington
Patients with Parkinson's disease (PD) sometimes experience symptoms affecting their movement, such as slowness, tremor, stiffness, and balance or walking problems. Many patients also have other symptoms not related to movement, called non-motor symptoms, which may affect one's mood or emotions, memory or thinking, or cause one to see or hear things that aren't real (hallucinations) or believe things that aren't true (delusions). Hallucinations or delusions, together called psychosis, occur in up to 60% of PD patients at some point in time. Parkinson's disease psychosis can sometimes be associated with decreased quality of life, increased nursing home placement, increased rate of death, and greater caregiver burden. There are approximately 50,000 Veterans with Parkinson's disease receiving care in the VA, and up to 30,000 (60%) of them will experience psychosis at some point in time.
Quetiapine is an antipsychotic drug approved by the Food and Drug Administration (FDA) that is the most commonly used medication to treat PD psychosis, but more studies are needed to determine if it works for this condition and is also well tolerated and safe. Pimavanserin is a newer antipsychotic drug approved by the Food and Drug Administration (FDA) specifically to treat PD psychosis, but more studies are needed to determine if it works and its safety.
The purpose of this research is to gather additional information on the safety and effectiveness of both Quetiapine and Pimavanserin. By doing this study, the investigators hope to learn which of these medications is the most effective course of treatment for people with PD psychosis.

Decitabine + FLAG-Ida for Myeloid Malignancies
Seattle, Washington
This phase I/II trial studies the safety, side effects, and best dose of decitabine in combination with fludarabine, cytarabine, filgrastim, and idarubicin (FLAG-Ida) and total body irradiation (TBI) followed by a donor stem cell transplant in treating adult patients with cancers of blood-forming cells of the bone marrow (myeloid malignancies) that are at high risk of coming back after treatment (relapse). Cancers eligible for this trial are acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and chronic myelomonocytic leukemia (CMML). Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. The FLAG-Ida regimen consists of the following drugs: fludarabine, cytarabine, filgrastim, and idarubicin. These are chemotherapy drugs that work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Filgrastim is in a class of medications called colony-stimulating factors. It works by helping the body make more neutrophils, a type of white blood cell. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. TBI is radiation therapy to the entire body. Giving chemotherapy and TBI before a donor peripheral blood stem cell (PBSC) transplant helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. When the healthy stem cells from a donor are infused into a patient, they may help the patient's bone marrow make more healthy cells and platelets. Giving decitabine in combination with FLAG-Ida and TBI before donor PBSC transplant may work better than FLAG-Ida and TBI alone in treating adult patients with myeloid malignancies at high risk of relapse.

Frequently Asked Questions
How much do clinical trials in Seattle, WA pay?
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.
How do clinical trials in Seattle, WA work?
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 Seattle, WA 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 Seattle, WA 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 Seattle, WA 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 Seattle, WA?
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.
What are the newest clinical trials in Seattle, WA?
