Naltrexone for Drug Overdose Prevention
San Francisco, California
The goal of this clinical trial is to see if an injectable medicine called naltrexone can prevent fentanyl overdose deaths in people who use other drugs (cocaine, methamphetamine). The main questions it aims to answer are:
What are the challenges for implementing naltrexone as an overdose prevention strategy?
Are injections of naltrexone effective for opioid overdose prevention among people who use stimulants?
How often are people who use stimulants and do not intentionally use opioids unintentionally exposed to opioids?
Researchers will compare participants to receive the study medication to the usual care group to see if one group experiences fewer opioid overdose events than the other.
Participants will be randomized to either receive a monthly injection of naltrexone over six months, or receive usual care. Usual care includes harm reduction supplies. Laboratory procedures will include the collection of urine, blood, and hair samples for various safety and outcome measure testing.

IV Lidocaine for Postoperative Pain and Delirium
San Francisco, California
Postoperative delirium is one of the most frequent adverse events following elective non-cardiac surgery and is associated with cognitive impairment at discharge, as well as in-hospital and long-term mortality, however, despite being a well-recognized problem there is a dearth of effective interventions for prevention and management. A modifiable risk factor associated with postoperative delirium is poor postoperative pain control, and by improving the pain regimen the investigators may be able to decrease the incidence and/or severity of postoperative delirium. In this study, the investigators seek to study whether a postoperative intravenous infusion of lidocaine, known to improve pain control in other contexts, can decrease the risk of postoperative delirium and other opioid-related side effects, following major reconstructive spinal surgery.

MRgFUS vs. CTgRFA for Bone Tumors
San Francisco, California
Osteoid osteomas are painful, benign bone tumors that occur most frequently in young males between ages 10 and 20 years. The goal of the proposed study is based on the premise that MRgFUS is noninferior to CT-guided radiofrequency ablation (CTgRFA), in terms of pain reduction following treatment of osteoid osteomas, and offers possible improvements with regards to 1) post-procedural pain, 2) clinical resource utilization, 3) patient experience, and/or 4) adverse events. The data from the current study would provide clinicians important information in deciding between treatment options for ablation of osteoid osteomas.

Denosumab to Prevent Breast Cancer in Women With BRCA1 Mutation
San Francisco, California
This phase III trial compares denosumab to placebo for the prevention of breast cancer in women with a BRCA1 germline mutation. A germline mutation is an inherited gene change which, in the BRCA1 gene, is associated with an increased risk of breast and other cancers. Denosumab is a monoclonal antibody that is used to treat bone loss in order to reduce the risk of bone fractures in healthy people, and to reduce new bone growths in cancer patients whose cancer has spread to their bones. Research has shown that denosumab may also reduce the risk of developing breast cancer in women carrying a BRCA1 germline mutation.

PrEP Adherence Intervention for HIV Prevention
San Francisco, California
In this study, "PrEP Intervention for people who Inject Substances and Use Methamphetamine" (PRIME), we propose to assess if using video directly observed therapy with real-time contingency management (VDOT-CM) may help people assigned male sex at birth who inject methamphetamine adhere to PrEP. We will randomize 140 adults who use methamphetamine, are HIV-negative, and have recently engaged in a sexual HIV risk behavior to VDOT-CM or counseling alone for 24 weeks.
The study aims are to (1) determine the efficacy of VDOT-CM compared to counseling alone for PrEP adherence, (2) evaluate the acceptability of PrEP and adherence support strategies among the cohort, and (3) compare injection or chemsex and sexual HIV risk behavior before and during PrEP use.
We hypothesize that participants randomized to VDOT-CM will have superior adherence to PrEP. We also hypothesize that participants will describe barriers to and facilitators of PrEP adherence, and those who are randomized to VDOT-CM will consider it an acceptable PrEP adherence support strategy. Finally, we do not expect to find increased injection, chemsex, or sexual risk behaviors for HIV among study participants after they begin taking PrEP.

Moisturizers for Aging
San Francisco, California
This is a randomized, investigator-blinded, self-controlled pilot study of the physiologic response to topical moisturizers among older adults with dry skin. The overarching hypothesis is that skin barrier decline is an important source of chronic inflammation, and that skin barrier restoration with moisturizers can reduce serum biomarkers of inflammation. The primary objective is to determine the feasibility for a larger trial, and the secondary objectives are to determine the extent to which measures of serum inflammation, skin barrier function, and the skin microbiome change in response to moisturizers. Participants will be asked to apply one of two topical moisturizers that are widely available over the counter in the US (Vaseline® 100% pure petroleum jelly or CeraVe® moisturizing cream) once daily for 4 weeks to the front of the torso, buttocks, arms, and legs. Subjects will act as their own control (i.e. they will be asked to apply the study moisturizer they are randomized to for one intervention period (4 weeks) and not to apply topical moisturizers for the other 4- week intervention period). Participants will be randomized in a 1:1:1:1 ratio to one of 4 treatment groups: i. no intervention then CeraVe; ii. CeraVe then no intervention; iii. no intervention then Vaseline; iv. Vaseline then no intervention. At each visit (baseline, week 4, and week 8), participants will undergo skin barrier testing, skin microbiome sampling, and phlebotomy to measure serum inflammatory markers.

Pimavanserin vs. Quetiapine for Psychosis in Parkinson's Disease
San Francisco, California
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.

Intraosseous Antibiotics for Joint Infections
San Francisco, California
Purpose of Study: In order to improve upon the variable results seen in irrigation and debridement for periprosthetic infection, we ask if the use of intraosseous regional administration of antibiotics at the time of irrigation and debridement will improve the modest success of standard irrigation and debridement. We will use the existing literature on standard irrigation and debridement procedures to compare with the results of the irrigation and debridement with the use of intraosseous antibiotics.
Impact Question:
How will this study benefit the patient? Currently when an I\&D fails, the patient needs to undergo two more major procedures: 1) implant removal and 2) reimplantation of the prosthesis. Any improvement in the results of a standard irrigation and debridement procedure may decrease the number of patients having to go through further extensive procedures to cure their infection.

Maraviroc for Primary Graft Dysfunction
San Francisco, California
Lung transplant recipient survival lags other solid organ recipients, with the main early cause of death being primary graft dysfunction (PGD). PGD occurs in up to 1/3 of all recipients, is driven by the body's innate immune response, and has no known medical therapies for treatment or prevention. Investigators have recently shown that Natural Killer (NK) cells, a key innate immune cell, are critical in causing PGD. Importantly, the investigators found that Maraviroc, an FDA-approved drug that works to inhibit these immune cells, prevented lung injury in mouse models of PGD.
The goal of this clinical trial is to learn if Maraviroc works to treat PGD in Lung Transplant patients who are above the age of 18 and have a PGD risk score greater than 50%. The objectives the study hopes to address are:
To address the safety and tolerability of Maraviroc. To test a strategy for PGD enrichment in a lung transplant population. To measure the efficacy and biological efficacy of using Maraviroc. To study the biochemical, physiologic, and molecular effects of the drug on the body.
This will be a double blind study where patients will either get the Maraviroc drug or a placebo. Researchers will then compare the two groups to address the above objectives.
Participants will:
Take drug Maraviroc or a placebo every 12 hours for 3 days post surgery. Follow up will occur during the entire length of stay at UCSF, about 16 days, with a single 12 month follow up once released.

Stem Cell Therapy for Male Infertility
San Francisco, California
Purpose:
This clinical trial aims to explore the potential for human sperm production in vitro by sustaining a laboratory-cultured adult testicular environment. It also seeks to identify genetic factors contributing to human sterility and failed spermatogenesis. The study's primary objectives include:
1. Identifying genomic markers associated with sterility and failed spermatogenesis.
2. Developing an ex vivo (outside the body) testis "organ-on-a-chip" ("iTestis") to support stem cell cultivation.
3. Determining whether human spermatogenesis can be re-created in vitro using stem cells nurtured in the iTestis model.
Study Description:
Researchers will analyze the genomic profiles of fertile and sterile male participants to map genetic abnormalities associated with sterility. Using testicular and skin tissue samples from participants, spermatogonial stem cells and pluripotent stem cells will be isolated and utilized to construct the ex vivo iTestis. This system will integrate genomic insights and prior research to foster human spermatogenesis outside the body.
Participant Involvement:
Participants will provide the following samples:
* Blood sample for serum analysis.
* A skin tissue biopsy.
* Testicular tissue, obtained through fine needle aspiration (FNA) or testicular sperm extraction (TESE), as part of a routine procedure.
All procedures will be conducted by the principal investigator and qualified research staff, ensuring participant safety and adherence to ethical guidelines.

Frequently Asked Questions
How much do clinical trials in San Francisco, CA 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 San Francisco, CA 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 San Francisco, CA 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 San Francisco, CA 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 San Francisco, CA 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 San Francisco, CA?
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 San Francisco, CA?
Most recently, we added Hiltonol for HIV Prevention, GNTI-122 for Type 1 Diabetes and Urea in Dialysis Fluid for Renal Disease to the Power online platform.
