Clinical trials

The goal for this multidisciplinary randomized controlled trial (RCT) is to actively and meaningfully engage outdoor workers (can include agricultural workers, construction workers, landscaping, wildland firefighters, fire cleanup crews, etc.) and community members in describing the impact of climate change on their lives and working conditions in San Joaquin Valley, Kings County, and Monterey County. Participants will be randomly assigned to one of two study arms: (1) the Intervention Group, which will receive bilingual (Spanish and English) Cal/OSHA educational materials and engage in the Our Voice participatory action research (photovoice) method using a bilingual (Spanish and English) mobile application, or (2) the Control Group, which will only receive bilingual (Spanish and English) Cal/OSHA educational materials. Core outcomes will be measured identically across both groups to allow direct comparison of the two approaches. Using the "Our Voice participatory action research method" and Cal/OSHA educational materials, the investigators will learn about participants' attitudes, behaviors, and actions in response to changing climate in the counties and evaluate whether the education and photovoice approach is more impactful than traditional didactic Cal/Osha education only.

This is a single-site, open-label Phase I treatment study evaluating the manufacturing feasibility and safety of chimeric antigen receptor (CAR) T cells targeting the oncofetal protein Glypican-2 (GPC2) in pediatric and young adult patients with recurrent or refractory (R/R) medulloblastoma. Subjects with other non-medulloblastoma CNS embryonal tumors may enroll.

The purpose of this pilot study is to compare by pathological findings surgical excision versus neoadjuvant radiotherapy followed by delayed surgical excision of ductal carcinoma in situ (DCIS)

The unmet medical need in solid organ transplantation is to eliminate the lifelong requirement of powerful immune suppression drug combinations with their attendant side effects, and to prevent immune mediated rejection of the organ transplant. The proposed trial is designed to study if following a 'standard of care' deceased donor liver transplant host conditioning using Total Lymphoid Irradiation (TLI) and Anti-Tthymocyte Globulin (ATG) will result in operational tolerance and ultimately allow for immunosuppression drug minimization or cessation. It has been hypothesized that the ATG and TLI conditioning regimen post liver transplant will be safe and well tolerated and will result in recipients successfully being withdrawn from immunosuppression within 2 years after liver transplantation. We will test the hypothesis that by using a conditioning regimen of ATG and TLI to induce this operational tolerance will allow immunosuppressive drug minimization and cessation while maintaining normal graft function and without the risk of graft rejection. Importance of this knowledge: Operational tolerance occurs spontaneously in a minority of liver transplant recipients; however, predictable and reproducible induction of tolerance remains an unmet need. Building on extensive experience with TLI-based tolerance induction in kidney transplantation at Stanford, this study aims to evaluate whether a non-myeloablative conditioning regimen using TLI and ATG can safely facilitate immunosuppression minimization and withdrawal in liver transplant recipients without the use of donor hematopoietic cell infusion.

The purpose of this study is to examine the use of hypofractionated accelerated radiation therapy (HART) to treat locally advanced lung cancer. Depending on the location and size of the tumor.

The goal of this clinical trial is to learn whether immersive technology (virtual reality) headsets can reduce procedural pain and anxiety during diagnosis, intralesional and intramuscular injections, and wound/dressing care in pediatric patients 5 years of age and older and adult patients with cutaneous leishmaniasis receiving treatment at the MSF clinic in Peshawar, Khyber Pakhtunkhwa, Pakistan.

This pilot study will evaluate the safety, tolerability, and feasibility of Ultrasonic Debris Clearance (UDC), a noninvasive low-intensity focused ultrasound intervention, in amyloid-positive adults who are asymptomatic but at risk for Alzheimer's disease, or who have mild cognitive impairment or mild dementia. The study is designed to test whether repeated UDC sessions can be delivered safely and feasibly in this population, while also exploring efficacy via biomarkers and clinical measures.

This study is a pilot feasibility randomized trial involving newly diagnosed colorectal cancer (CRC) patients who identify as Latinx. The study aims to leverage existing academic-community partnerships in Santa Clara County to develop and evaluate a multi-level community health worker/promotora (CHW/P) navigator intervention. If found effective, APOYO has the potential to affect clinical outcomes for Latinx colorectal cancer patients both directly and indirectly, including improving health-related quality of life, health care utilization, and reducing social needs.

This phase I/II trial studies the best dose and timing of panitumumab-IRDye800 in detecting cancer in participants with lung cancer during the surgery. Panitumumab-IRDye800 is a combination of the antibody drug panitumumab and IRDye800CW, an investigational dye that can be seen using a special camera. Panitumumab-IRDye800 may attach to tumor cells and make them more visible during surgery in patients with lung cancer.

Hospitalization strips pediatric patients of the environments, objects, and people that shape their daily lives. Hospitalized pediatric patients routinely experience painful procedures, psychological distress, boredom, and a disorienting loss of personal identity. These experiences measurably worsen anxiety, reduce cooperation with care, and diminish the quality of the inpatient experience for both patients and families. Immersive digital interventions, including VR and tablet-based experiences, have emerged as a promising class of tools for addressing these challenges. Prior studies from The Stanford Chariot Program have demonstrated that digitally delivered, patient-centered experiences can meaningfully reduce procedural anxiety and improve engagement in hospitalized children. Yet, an important limitation persists in these technologies - current digital interventions largely remain in one-size-fits-all formats. Every child receives the same content, regardless of who they are, what they love, or what makes them feel at home in the world. This design limits therapeutic relevance, constrains engagement, and represents a missed opportunity to engage children, reduce anxiety, and enhance their quality of life during hospital stays.

This pilot feasibility study will evaluate the feasibility and acceptability of delivering Empowered Relief (ER), a single-session pain management intervention, to postpartum patients experiencing severe pain following cesarean delivery during the inpatient period. Participants will be enrolled during their inpatient postpartum hospitalization and randomized 1:1 to receive either ER in addition to standard postpartum care or standard postpartum care alone. Participants will be followed for 12 weeks postpartum.

The goal of this study is to test whether anesthesia-induced experiences can help alleviate symptoms of PTSD in an (1) open-label trial (Phase I) and (2) single-center double-blind, randomized, active-comparator (dose-controlled) participant-and assessor-blinded Phase 2 clinical trial (Phase II) in a non-surgical setting. Participants will undergo EEG-guided propofol anesthesia during which they will be either (1) receiving a sedation protocol associated with dream experiences upon emergence (Dream Condition), and/or (2) a sedation protocol associated with non-dream experiences (Non-Dream Condition). The investigators will then investigate whether the Dream Condition is associated with a larger reduction in PTSD symptoms than the Non-Dream Condition.

The goal of this clinical trial is to learn if the "Insul-In This Together" family program works to improve outcomes for adolescents living with type 1 diabetes. It will also learn about how the program influences diabetes-related factors, including parenting. The main questions it aims to answer are: Does this program improve glycemic (blood glucose) outcomes? Does this program improve adolescent quality of life related to diabetes? Researchers will offer the program to all participating families, with one group receiving the program right after enrollment and another group receiving the program 6 months later. Adolescent and parent participants will: Attend 8 weekly 30-minute videoconference sessions with an interventionist Complete online surveys, share diabetes device data, and conduct at-home A1c tests 3-5 times over a 12-month period

The goal of this clinical trial is to characterize regional intestinal fermentation physiology and determine how the response to fermentable dietary fiber differs between healthy individuals and individuals with irritable bowel syndrome (IBS). The study will use ingestible capsule technologies to directly measure intestinal gases and regional microbiome composition following low-fiber and high-fiber meal challenges. The main questions it aims to answer are: Does the change in regional intestinal gas levels following a fermentable-fiber challenge differ between participants with IBS and healthy controls? How are regional intestinal gas dynamics associated with microbiome composition, breath gases, serum short-chain fatty acids, glucose dynamics, metabolites, and gastrointestinal symptoms? Researchers will compare participants with IBS to healthy controls to determine whether intestinal fermentation responses to dietary fiber differ between these populations. Participants will: Complete two study visits approximately one week apart. At one visit, participants will receive a low-fiber control meal, and at the other visit, they will receive the same base meal containing 15 g of inulin. The order of the two meals will be assigned at random. Swallow an Atmo gas-sensing capsule to measure intestinal H2, CO2, and O2 and a CapScan capsule to collect regional intestinal fluid for microbiome analysis. Undergo serial blood and breath sampling and gastrointestinal symptom assessments during each 8-hour study visit. Complete stool and urine collections, dietary assessment, and continuous glucose monitoring before and/or after the study visits.

Intensive conditioning regimens used in allogeneic hematopoietic cell transplant (HCT) help to eliminate hematologic tumors and reduce the risk of relapse, but are also characterized by high toxicity. Total marrow and lymphoid irradiation (TMLI) is a specialized radiation technique that specifically targets marrow and lymphoid tissue to maximize antitumor efficacy while reducing off target toxicity. Despite these benefits, TMLI is technically challenging and time consuming. The radiation oncology team at Stanford has developed an automated TMLI platform to overcome these challenges. In this phase II trial, automation will be incorporated into a previously validated conditioning regimen of fludarabine/cyclophosphamide/TMLI HCT with post-transplant cyclophosphamide (PTCy) for graft-versus-host disease (GVHD) prophylaxis to confirm the feasibility and safety of automation in patients receiving allogeneic HCT for high-risk myeloid malignancies.

The goal of this clinical trial is to learn if a novel digital strategy combining a generative AI counseling agent (MICA) and weekly SMS boosters works to reduce risky drinking among Emergency Department patients.

The purpose of this study is to test whether or not number of circulating cancer cells detected in the blood can be decreased the by combining the standard treatment (durvalumab) with Tremelimumab and additional chemotherapy

The objective of the study is to assess safety of panitumumab-IRDye800 in pediatric patients undergoing brain surgery to remove suspected tumors.

Past modest, transient and highly variable outcomes from many behavioral treatments for pediatric obesity may be, in part, because of the psychological barriers children with obesity face when trying to control their weight. The goal of this randomized controlled trial is to test whether adding two innovative, brief, social psychological activities (termed "wise" interventions) to a high quality, family-based, group behavioral weight control program, will produce better outcomes among participating children with obesity. The primary hypothesis is that children who receive the family-based, group, behavioral weight control program plus the wise social psychological interventions will have significantly less body mass index growth over 12 months than children who receive the family-based, group, behavioral weight control program plus additional educational content. Participants will be asked to do participate in the six month treatment program and complete measurements at the beginning of the study, after 3 months, after 6 months (the end of the behavioral treatment program), and after 12 months (6 months after completing the behavioral treatment program). This study has the potential to substantially improve the outcomes of pediatric weight control treatments and significantly reduce concurrent and future health, psychological and social harms from childhood obesity.

The investigators are hoping to determine whether tailoring the diet of someone with type 2 diabetes to their ethnic group while following American Diabetes Association guidelines can make a significant difference in their blood sugar controls. Participants will be required to wear a Continuous Glucose Monitor (CGM) for 1-month so that the investigators can compare blood sugar levels when participants are eating their routine diet vs. the culturally tailored diabetes diet.

This pilot study will evaluate the feasibility and acceptability of delivering Empowered Relief (ER), a single-session pain relief skills class, to postpartum women with ongoing pain and/or pain interference following cesarean delivery. Participants will receive ER in addition to standard postpartum care and will be followed through 12 weeks postpartum.

Children and teenagers who receive a solid organ transplant (such as a kidney, liver, or heart) must take medications every day to keep their new organ healthy. Taking these medications correctly and on time is one of the most important parts of staying well after a transplant, but it can be hard for young patients to understand why this matters and to keep up with their routines. Doctors and nurses usually teach patients about their transplant through conversations, which may not always be engaging or easy for kids to remember. This study looks at a new way to help young transplant patients learn about their condition and their medications: an educational game played on a tablet. The purpose of the study is to find out what patients think of the game and how well it works for them. Researchers want to know whether young patients find the game acceptable and enjoyable, whether it is easy to use, whether it makes them feel motivated and capable, and how engaged they feel while playing. To do this, patients will play the tablet game and then share their experiences. After playing, they will take part in a small group interview where they talk about what they liked, what was confusing, and whether the game helped them understand their transplant and medications. They will also fill out short questionnaires about how easy the game was to use and how engaging it felt. The researchers' hypothesis is that pediatric solid organ transplant patients will find the educational tablet-based game acceptable, easy to use, and engaging, and that it will be a welcome and helpful tool for learning about their transplant care. The findings will help guide whether this kind of game could be used to support transplant education for children and teens.

In this randomized-controlled trial the investigators will examine the effect of oxygen supplementation on the recovery of breathing for 90 minutes in the immediate post-anesthesia period starting from extubation of the trachea.
