The purpose of this study is to determine the feasibility and impact of 28-days of monitored abstinence from cannabis use on symptoms of depression and anxiety, pain, sleep, cannabis use withdrawal, HIV viral load and biomarkers of systemic inflammation among PLWH and who use cannabis regularly (weekly or more often). This will be a single arm pilot feasibility trial involving a contingency management program to induce cannabis abstinence. Specifically, the contingency management program will provide motivational (monetary) incentives to participants who achieve biochemically verified cannabis abstinence. Over the 28-days of this pilot feasibility trial, participants will attend seven study visits. During these visits, participants will complete survey questionnaires to assess sociodemographic, psychosocial, and behavioral factors. In addition, participants will provide blood and urine specimens for testing and quantitation of HIV viral load, biomarkers of systemic inflammation and for the detection of cannabis and other drugs of abuse.

This research study is to find out if brain stimulation at different dosage level combined with an efficacy-proven rehabilitation therapy can improve arm function. The stimulation technique is called transcranial direct current stimulation (tDCS). The treatment uses direct currents to stimulate specific parts of the brain affected by stroke. The adjunctive rehabilitation therapy is called "modified Constraint-Induced Movement Therapy" (mCIMT). During this therapy the subject will wear a mitt on the hand of the arm that was not affected by a stroke and force to use the weak arm. The study will test 3 different doses of brain stimulation in combination with mCIMT to find out the most promising one.

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).

The purpose of this research study is to understand the long-term effects of the drug phentermine on weight, blood pressure, other health outcomes, and safety. Phentermine has been approved by the US Food and Drug Administration (FDA) for weight management since 1959, but it has not been approved for long-term use (i.e., treatment lasting more than 12 weeks). This trial is designed to learn about the long-term effects of phentermine for up to 2 years because obesity is a chronic disease and expert guidelines recommend long-term use of anti-obesity medications as one treatment option.

Huntington's Disease (HD) is an autosomal dominant disease manifested in a triad of cognitive, psychiatric, and motor signs and symptoms. HD is caused by a triplet repeat (CAG)expansion in the gene Huntingtin (HTT). This disease has classically been conceptualized as a neurodegenerative disease. However, recent evidence suggests that abnormal brain development may play an important role in the etiology of HD. Huntingtin (HTT)is expressed during development and through life. In animal studies, the HTT gene has been shown to be vital for brain development. This suggests that a mutant form of HTT (gene-expanded or CAG repeats of 40 and above) would affect normal brain development. In addition, studies in adults who are gene-expanded for HD, but have not yet manifested the illness, (pre-HD subjects) have significant changes in the structure of their brain, even up to 20 years before onset of clinical diagnosis. How far back these changes are evident is unknown. One possibility is that these brain changes are present throughout life, due to changes in brain development,though initially associated with only subtle functional abnormalities. In an effort to better understand the developmental aspects of this brain disease, the current study proposes to evaluate brain structure and function in children, adolescents, and young adults (ages 6-30) who are at risk for developing HD - those who have a parent or grandparent with HD. Brain structure will be evaluating using Magnetic Resonance Imaging (MRI) with quantitative measures of the entire brain, cerebral cortex, as well as white matter integrity via Diffusion Tensor Imaging. Brain function will be assessed by cognitive tests, behavioral assessment, and physical and neurologic evaluation. Subjects that are gene-expanded (GE) will be compared to subjects who are gene non-expanded (GNE). Changes in brain structure and/or function in the GE group compared to the GNE group would lend support to the notion that this disease has an important developmental component.

The objective of the rFVIIa for Acute Hemorrhagic Stroke Administered at Earliest Time (FASTEST) Trial is to establish the first treatment for acute spontaneous intracerebral hemorrhage (ICH) within a time window and subgroup of patients that is most likely to benefit. The central hypothesis is that rFVIIa, administered within 120 minutes from stroke onset with an identified subgroup of patients most likely to benefit, will improve outcomes at 180 days as measured by the Modified Rankin Score (mRS) and decrease ongoing bleeding as compared to standard therapy.

In parallel with the growth of American Thrombosis and Hemostasis Network's (ATHN) clinical studies, the number of new therapies for all congenital and acquired hematologic conditions, not just those for bleeding and clotting disorders, is increasing significantly. Some of the recently FDA-approved therapies for congenital and acquired hematologic conditions have yet to demonstrate long-term safety and effectiveness beyond the pivotal trials that led to their approval. In addition, results from well-controlled, pivotal studies often cannot be replicated once a therapy has been approved for general use.(1,2,3,4) In 2019 alone, the United States Food and Drug Administration (FDA) has issued approvals for twenty-four new therapies for congenital and acquired hematologic conditions.(5) In addition, almost 10,000 new studies for hematologic diseases are currently registered on www.clinicaltrials.gov.(6) With this increase in potential new therapies on the horizon, it is imperative that clinicians and clinical researchers in the field of non-neoplastic hematology have a uniform, secure, unbiased, and enduring method to collect long-term safety and efficacy data. ATHN Transcends is a cohort study to determine the safety, effectiveness, and practice of therapies used in the treatment of participants with congenital or acquired non-neoplastic blood disorders and connective tissue disorders with bleeding tendency. The study consists of 7 cohorts with additional study "arms" and "modules" branching off from the cohorts. The overarching objective of this longitudinal, observational study is to characterize the safety, effectiveness and practice of treatments for all people with congenital and acquired hematologic disorders in the US. As emphasized in a recently published review, accurate, uniform and quality national data collection is critical in clinical research, particularly for longitudinal cohort studies covering a lifetime of biologic risk.(7)
