11C-YJH08 PET Imaging for the Detection of Glucocorticoid Receptor Expression in Patients With Metastatic Prostate Cancer

Study Type: Interventional
Start Date: August 10, 2021
Location: San Francisco, California
Eligibility: Males, Ages 18 and Older, Does Not Accept Healthy Volunteers

This phase I trial studies if positron emission tomography (PET) imaging using 11C-YJH08 can be useful for detecting certain cell receptor expression in tumor cells in patients with prostate cancer that has spread to other parts of the body (metastatic). 11C-YJH08 is a small-molecule radiotracer that binds to receptors on cells (glucocorticoid receptor) so that they show up better on the PET scan. Anti-hormone therapy (including enzalutamide) can cause more glucocorticoid receptors to be produced in tumor cells, which can make the tumor cells resist hormone therapies. If researchers can find a better way to detect whether glucocorticoid receptors are increasing during therapy, it may lead to more successful therapies using glucocorticoid receptor antagonists.

Enhancing Partner Services Among Men Who Have Sex With Men Living With HIV

Study Type: Interventional
Start Date: August 1, 2021
Location: Guangzhou, Guangdong, China
Eligibility: Males, Ages 18–99, Does Not Accept Healthy Volunteers

Individuals will participate in a pilot randomized controlled trial (RCT) that implements and evaluates the feasibility, acceptability, and effectiveness of crowdsourced partner services (PS) or conventional PS among Chinese men who have sex with men (MSM) living with HIV.

The pilot RCT will include 120 newly identified MSM HIV cases who were born biologically male, aged 18 years old or older, newly identified as HIV positive, had oral or anal sex with a man, had at least one sexual partner in the previous 6 months and live in Guangzhou. Participants will undergo a series of computer-based interviews (baseline and 2 months after enrollment) and will be randomly assigned into two groups in 2:1 ratio (intervention: control) and receive crowdsourced PS and conventional PS, respectively.

Developing Online Interventions to Reduce Stigma-Related Stress, Sexual Health, and HIV Risk Among Young Chinese MSM

Study Type: Interventional
Start Date: April 19, 2021
Location: Hunan, China
Eligibility: Males, Ages 16–30, Accepts Healthy Volunteers

This study is a 2-arm RCT that will assess the efficacy of a culturally adapted, 10-session SGM-affirmative, internet-based cognitive behavioral therapy (iCBT) among young men who have sex with men (YMSM) in Hunan province China. The affirmative treatment called ESTEEM is based on a minority stress-focused, CBT framework. In collaboration with colleagues at Central South University (CSU), the investigators will assess whether a culturally adapted version of iCBT ESTEEM demonstrates significant reductions in HIV risk behavior and mental health symptoms (e.g., depression, anxiety) compared to self-monitoring of stress and mood.

Reducing Intersectional Stigma Among High-Risk Women in Brazil to Promote Uptake of HIV Testing and PrEP

Study Type: Interventional
Start Date: December 1, 2020
Location: São Paulo, Brazil
Eligibility: Males, Ages 18 and Older, Accepts Healthy Volunteers

This is a randomized controlled trial of a multi-level intervention to prevent HIV acquisition among transgender women (N=400) in São Paulo, Brazil. The intervention will be evaluated using a randomized wait-list controlled trial to compare uptake of HIV testing (self-testing and clinic-based) (Aim 1), PrEP initiation and persistence (Aim 2), and other prevention services (e.g. harm reduction) among trans women in the intervention arm compared to those in the control arm with data collection scheduled every three-months. Investigators will assess changes in intersectional stigma (Aim 3), including reductions in internalized stigma and increased resilience to anticipated and enacted stigma, among those assigned to intervention compared to those assigned to the control arm, and assess how changes in stigma result in prevention uptake.

An Avatar-based Mobile Phone Intervention to Promote Health in African American MSM

Study Type: Interventional
Start Date: March 4, 2020
Location: Chicago, Illinois
Eligibility: Males, Ages 18–34, Does Not Accept Healthy Volunteers

The investigators propose to determine the efficacy of "My Personal Health Guide," a theory-based innovative talking relational human Avatar mobile phone application to engage HIV-positive AAMSM in adherence and retention in care. Providing an empathetic talking Avatar source of HIV-related information, motivation, and behavioral skills that is as private and convenient as their own mobile phone might produce a high impact by overcoming barriers to HIV adherence and retention in care such as stigma and health literacy.

Improving Health Outcomes in Young Cisgender Men and Transgender Women (mLab App)

Study Type: Interventional
Start Date: January 21, 2020
Locations: Chicago, Illinois; New York, New York
Eligibility: Males, Ages 18–29, Accepts Healthy Volunteers

The mLab App combines HIV prevention information with push notifications/reminders to complete HIV testing and an automated image processing feature to provide real-time feedback on home-based HIV test results. Theoretically-guided by the Health Information Technology Usability Evaluation Model (Health-ITUEM), the proposed project will refine and test a next-generation diagnostic intervention delivered on a mobile platform to improve HIV testing and linkage-to-care outcomes among youth living with and at-risk for HIV. Given the pervasiveness, low cost, and convenience of mobile technology, the investigators hope that the App can help achieve the goals of the National HIV/AIDS Strategy in the US by increasing the number of persons living with HIV who know their serostatus, decreasing HIV-related disparities, and ultimately reducing the risk of HIV transmission and acquisition.

Pre-exposure Prophylaxis (PrEP) at Home

Study Type: Interventional
Start Date: April 26, 2019
Locations: Atlanta, Georgia; Boston, Massachusetts; Jackson, Mississippi; Saint Louis, Missouri; Cleveland, Ohio
Eligibility: Males, Ages 18–49, Accepts Healthy Volunteers

This study is a randomized clinical trial of PrEP@Home, a home care system for Human Immunodeficiency Virus (HIV) Pre-Exposure Prophylaxis (PrEP). Individuals entering into PrEP care at an initial in-person study visit will be randomized to the PrEP@Home system for home-based PrEP care follow-up visits or to the control standard of care for clinic-based follow-up visits. The primary aim of this study is to assess protective levels of PrEP medication for the intervention arm compared to the control arm.

eTest: Real-time, Remote Monitoring System for Home-based HIV Testing Among High-risk Men Who Have Sex With Men

Study Type: Interventional
Start Date: January 23, 2019
Location: Providence, Rhode Island
Eligibility: Males, Ages 18 and Older, Accepts Healthy Volunteers

The proposed research will conduct a fully-powered efficacy trial of this approach in areas with large populations of AA and H/L MSM and high HIV incidence: Jackson, MS, Los Angeles, CA, and Boston, MA. High-risk MSM who have not tested for HIV in the last year will be recruited from MSM-oriented "hook-up" mobile apps, and assigned to receive either (1) HBST with post-test phone counseling/referral ("eTEST" condition), (2) "standard" HBST without active follow-up, or (3) reminders to get tested for HIV at a local clinic ("control" condition) at three month intervals over the course of 12 months. The investigators will explore the impact of the eTEST system on key outcomes, including rates of HIV testing, receipt of additional HIV prevention services, and PrEP initiation, compared with standard HBST or clinic-based testing reminders alone. The investigators will also explore the cost effectiveness of the eTEST system under various scenarios compared with relying on traditional, clinic-based testing alone.

Black Men's Care, and Intervention to Re-Engage HIV+ Black Men in Care

Study Type: Interventional
Start Date: May 25, 2018
Location: San Francisco, California
Eligibility: Males, Ages 18 and Older, Does Not Accept Healthy Volunteers

The proposed study aims to develop an intervention that is strategic in that it will 1) be a focused on an approach that combines an in-person session with post-session, two-way text messaging to continue the intervention and reinforce the gains from the in-person session and 2) ultimately find HIV+ Black men who have sex with men who have left HIV care where they are likely to present (e.g., city and county health clinics, community-based organizations, emergency rooms).

Imaging Cannabinoid Receptors Using Positron Emission Tomography (PET) Scanning

Study Type: Observational
Start Date: July 31, 2010
Location: New Haven, Connecticut
Eligibility: Males, Ages 18–55, Accepts Healthy Volunteers

The aim of the present study is to assess the availability of cannabinoid receptors (CB1R) in the human brain. CB1R are present in everyone's brain, regardless of whether or not someone has used cannabis. The investigators will image brain cannabinoid receptors using Positron Emission Tomography (PET) imaging and the radioligand OMAR, in healthy individuals and several conditions including 1) cannabis use disorders, 2) psychotic disorders, 3) prodrome of psychotic illness and 4) individuals with a family history of alcoholism, 5) Post-Traumatic Stress Disorder 6) Opioid Use Disorder using the PET imaging agent or radiotracer, [11C]OMAR. This will allow us to characterize the number and distribution of CB1R in these conditions. It is likely that the list of conditions will be expanded after the collection of pilot data and as new data on cannabinoids receptor function and psychiatric disorders becomes available.

Those in the cannabis us disorder arm of the study will have a PET scan on at least three occasions: once while smoking as usual, once after 48-hours of abstinence from cannabis, and a final time after 4 weeks of abstinence. Additional scans may be conducted within the 4 weeks and the last scan may be conducted well beyond 4 weeks. Similarly, while most schizophrenia patients may get scanned just once, a subgroup of patients may get scanned more than once. For example to tease out the effects of medications, unmedicated patients may get scanned while unmedicated and again after treatment with antipsychotic medications. Similarly prodromes may get scanned while in the prodromal stage off medications, on medications and after conversion to schizophrenia.
