This pilot trial studies the side effects of ifetroban in treating patients with malignant solid tumors that are at high risk of coming back after treatment and spreading throughout the body. Platelets are a type of blood cells that help with clotting. Cancer cells stick to platelets and ride on them to get to different parts of the body. Drugs, such as ifetroban, may help these platelets become less "sticky," and reduce the chance of cancer cells spreading to other places in the body.

A phenome-wide association study (PheWAS) identified an association between a variant in the human gene for the N2A subunit of the N-methyl-D-aspartate (NMDA) receptor, GRIN2A, and Systemic Lupus Erythematosus (SLE). A single nucleotide polymorphism (SNP) in this gene encodes for increased NMDA receptor activity. Based on the potential function of the associated SNP and published literature, alterations in SNP function signaling may underlie a cluster of symptoms. The objective of this study is to evaluate the safety, tolerability and efficacy of memantine, an NMDA receptor antagonist, in a precise patient subset with SLE. Participants will complete a full 14-week clinical trial, receiving either memantine or a placebo. Participants' blood will be drawn to test for various antibodies as well as organ function. Patients' urine will also be collected to assess organ function and pregnancy for females at a number of specific time points. The overall goal is to develop a safe and inexpensive therapeutic approach to reduce debilitating cognitive symptoms in a precisely selected SLE sub-population.

The purpose of the Trial-Ready Cohort - Down Syndrome (TRC-DS) is to enroll 120 healthy adults with Down syndrome (DS), between the ages of 25-55, into a trial ready cohort (TRC), and up to 250 participants in total including co-enrolled in the Alzheimer Biomarkers Consortium - Down Syndrome (ABC-DS) study. Participants enrolled in the TRC-DS will undergo longitudinal cognitive and clinical assessment, genetic and biomarker testing, as well as imaging and biospecimen collection. Using these outcome measures, researchers will analyze the relationships between cognitive measures and biomarkers of Alzheimer's disease (AD) to identify endpoints for AD clinical trials in DS that best reflect disease progression. To learn more about the study and participating sites, visit our study website at: https://www.trcds.org/. TRC-DS is collaborating with the Alzheimer's Disease Biomarker Consortium-Down Syndrome (ABC-DS) to allow study participants to be concurrently enrolled in both ABC-DS and TRC-DS, referred to as "co-enrollment". ABC-DS is a longitudinal, observational research study that is overseen at University of Pittsburgh Coordinating Center. ABC-DS participants who express interest in potentially joining a clinical trial in the future and who meet TRC-DS eligibility criteria, may choose to co-enroll in TRC-DS at an ABC-DS Site. Co-enrolled participants will adhere to the ABC-DS protocol and schedule of activities, but agree to share their data with the TRC-DS team and to receive invitations for future participation in clinical trials.

Neurofibromatosis Type 1 (NF1) is a common genetic disorder that is associated with a four times greater risk of learning disabilities, including reading disabilities, and a deficiency of neurofibromin - a protein important in a signaling pathway that regulates learning and memory. Our previous work (NS49096) demonstrated that school-age children with NF+RD can respond to standard phonologically-based reading tutoring originally developed to treat reading disability in the general population. Combining our work with that by other researchers suggesting that a medication (Lovastatin) may counteract the effects of the deficient neurofibromin, and possibly ameliorate learning disabilities in NF1, the investigator propose to examine the synergistic effects of medication plus reading tutoring.

The primary purpose of this study is to see if people with HIV who had a significant weight gain after starting INSTI (integrase strand transfer inhibitor)+TAF/FTC (tenofovir alafenamide/emtricitabine) (TAF/3TC (lamivudine)) regimen could either slow their rate of weight gain or lose weight within about 1 year if they switch to a regimen containing doravirine (DOR; a newer, non-nucleoside reverse transcriptase inhibitor medication). The study will also try to see if participants changing from TAF/FTC (or TAF/3TC) to TDF/FTC (or TDF/3TC) will experience less additional weight gain or a reduction in overall body weight at 48 weeks compared to persons continued on an INSTI + TAF/FTC (or TAF/3TC) combination. INSTINs assessed in A5391 include bictegravir (BIC), dolutegravir (DTG), or raltegravir (RAL). Additionally, the study will see whether a change in ART can affect things like waist circumference, metabolic and cardiovascular health, fat and lean mass body composition, bone health, and maintenance of virologic suppression. Finally, the study will look at the safety and tolerability of DOR plus either TAF/FTC (or TAF/3TC) versus TDF/FTC (or TDF/3TC).

Chronic kidney disease (CKD) is a burden of morbidity and mortality. Increased protein breakdown in skeletal muscle (wasting) and ectopic fat deposition are important determinants of poor clinical outcome in patient with CKD. Insulin resistance plays a critical role in skeletal muscle wasting and ectopic fat deposition. Glucagon-like peptide-1 receptor agonists (GLP-1RA) decrease ectopic fat deposition in patients with type 2 diabetes, prediabetes, obese and overweight subjects. The influence of GLP-1RA on ectopic fat deposition in CKD patients in unknown. The investigators' will test the hypothesis that GLP-1RA decreases intermuscular (ectopic) fat deposition in patients with stage 3-4 CKD. The investigators' will do so by addressing the following specific aims: Specific Aim 1: To test the hypothesis that GLP-1RA decreases intermuscular fat deposition in patients with stage 3-4 CKD. Specific Aim 2: To test the hypothesis that GLP-1RA improves skeletal muscle mitochondrial function in patients with stage 3-4 CKD. Specific Aim 3: To test the hypothesis that GLP-1RA improves physical performance in patients with stage 3-4 CKD. Specific Aim 4: To test the safety and feasibility of 12 weeks of dulaglutide 1.5 mg/wk administration as an adjunct therapy to the standard care of patients with stage 3-4 CKD.

The most pervasive sensory manifestation of TS is sensory over-responsivity (SOR). SOR is defined as excessive behavioral response to commonplace environmental stimuli. SOR is an integral but poorly understood facet of the TS phenotype, one intertwined with core elements of the disorder and worse QOL. This proposal seeks to clarify the mechanistic bases of SOR in TS. Adults with with TS will be recruited 1) to complete a standardized clinical symptom assessment battery and 2) to undergo electroencephalogram (EEG), autonomic, and audio-visual monitoring during tactile and auditory stimuli paradigms, as well as at rest.
