Clinical trials

The goal of this clinical trial is to learn if Cognitive Behavioral Therapy for Depression in Autistic Youth (CBT-DAY) can improve depressive symptoms and related mechanisms in autistic youth aged 11-17 years with depression receiving care in outpatient clinical settings. The main questions it aims to answer are: * Does CBT-DAY lead to greater reductions in depressive symptom severity compared to treatment-as-usual (TAU)? * Does CBT-DAY improve key mechanisms (emotional reactivity, self-esteem, and autism self-knowledge) associated with depression outcomes? Researchers will compare CBT-DAY versus treatment-as-usual (TAU) to see if CBT-DAY results in greater improvements in depressive symptoms and related outcomes. Participants will: * Complete baseline, mid-treatment, post-treatment, and 3-month follow-up assessments (surveys and interviews) * Be randomly assigned to receive either 12 weeks of CBT-DAY or treatment-as-usual * Participate in therapy sessions during the 12-week intervention period * Complete follow-up assessments three months after treatment to evaluate longer-term outcomes

Correct use of daily medications containing inhaled corticosteroids is key for asthma control, yet children with intellectual and developmental disabilities (IDD) face additional barriers to proper inhaler use. Smart inhalers, a novel technology that provides guidance and immediate feedback on inhaler use techniques, have been shown to enhance correct medication administration in the typically developing pediatric population, but their effectiveness has not been evaluated on the pediatric IDD population for remote home use. This study aims to investigate whether daily application of smart inhalers (1) is feasible, acceptable and usable in the IDD population for remote asthma management, (2) improves the rate of medication use and correct medication administration, and (3) results in improvement in lung function. This effort aims to promote better asthma management in the IDD population for remote home use.

The goal of this clinical trial is to learn whether an optimized, multi-component mobile health intervention (ReSeT2) can reduce sedentary behavior in adolescents and young adults with acute lymphoblastic leukemia (ALL) who are receiving maintenance therapy. The participant population includes English-speaking adolescents and young adults aged 13-22 years with ALL or related lymphoid malignancies being treated at Children's Hospital Los Angeles. The main questions it aims to answer are: * Does the ReSeT2 intervention reduce device-measured total sedentary time (minutes/day) from baseline to Week 12 compared with usual care? * Does the ReSeT2 intervention improve other sedentary behavior measures, feasibility and acceptability outcomes, and exploratory health outcomes such as cardiometabolic health, quality of life, and self-efficacy? Researchers will compare participants receiving the ReSeT2 intervention with participants receiving usual care to see if the intervention leads to greater reductions in sedentary time and improvements in related health outcomes. Participants will: * Complete baseline and Week 12 assessments, including questionnaires, clinical measurements, laboratory tests, and 7-day accelerometer wear periods. * Be randomized to either the ReSeT2 intervention group or usual care. * If assigned to the intervention group: Use a Fitbit activity tracker with inactivity prompts for 10 weeks. Receive home activity equipment and goal-based incentives. Participate in individualized coaching sessions. Participate in a peer support GroupMe chat and optional in-person group sessions. If assigned to the usual care group, continue standard clinical care and complete study assessments.

The goal of this clinical trial is to identify the circuit activations by very brief exposure (VBE) among youth with social anxiety disorder (SAD) in order to develop a novel intervention for those with SAD. The secondary objectives of this study are to measure the effect of VBE on subjective fear ratings, and participants' awareness and tolerance of the exposure stimuli. * The primary outcome of this study is the mean activation of frontostriatal and prefrontal brain regions to facial stimuli, as measured by Blood Oxygen Level Dependent (BOLD) response, in 4 regions of interest during the magnetic resonance imaging (MRI). * Another primary outcome of the study is to identify networks of regions subserving emotion regulation and attention, as measured by BOLD response of corresponding brain regions. Secondary Outcomes -The secondary outcome of this study is the fear induced by exposure to facial expression stimuli as measured by a 4-point fear scale during the functional magnetic resonance imaging (fMRI) after each block of 10 facial expression stimuli trials. Participants will participate in an interview where they will answer questions both inside and outside of the MRI scan. Participants will be asked to rate on a scale the imagines they see while undergoing MRI scan.

The goal of this clinical trial is to develop a new behavioral treatment for U.S. combat veterans with post-traumatic stress disorder (PTSD), very brief exposure to combat-related stimuli. The main questions it aims to answer are: 1. How does Very Brief Exposure (combat images and control everyday images) and Visible Exposure to combat stimuli affect brain activity and subjective fear ratings? 2. To what extent are participants aware of the stimuli presented and tolerating the exposures? All participants will view both very brief exposure and visible exposure to combat stimuli in the functional magnetic brain imaging (fMRI) scan. They will provide ratings of fear, awareness, and tolerability. Researchers will compare U.S. combat veterans with PTSD and healthy controls to confirm differences in brain region activation and ratings.

The goal of this feasibility pilot trial is to finalize the design of a mobile health intervention for promoting medication adherence in a population of adolescents and young adults with chronic health conditions. The main question\[s\] it aims to answer are: 1. Is the final version of the intervention sufficiently feasible, usable, and acceptable for evaluation in a randomized clinical trial? 2. Do participants show improvements in medication adherence during their field testing of the intervention?

The goal of this clinical trial is to improve the successful healthcare transition from pediatric to adult-focused care for childhood cancer survivors. The main questions it aims to answer are * Receipt of the intervention (vs. standard of care control) will increase the proportion of CCS achieving transition success to adult-focused survivorship care from 50% to 70%. * Receipt of the intervention (vs. standard of care control) will significantly reduce patients' unmet HRSN. * Intervention effectiveness will be moderated by sociodemographic factors (gender, race/ethnicity, insurance status), medical risk for late effects, HRSN burden, and patient-reported outcomes (quality of life, self-efficacy). Researchers will compare those that receive intervention versus standard of care. Patients are randomized to either an intervention group, receiving structured PN-led sessions and tailored support for care transitions, or a control group receiving standard follow-up by a nurse case manager. High-HRSN patients in the intervention arm get monthly check-ins and coordinated handoffs to adult care providers for continuity.

Butyrate is an important metabolite produced by the gut microbiome and has been shown as a helpful therapy in ulcerative colitis. This is a feasibility study to determine the efficacy of butryate enemas in pediatric ulcerative colitis.

The purpose of this study is to develop a mechanism for utilizing the comprehensive clinical database of childhood cancer survivors at Childrens Hospital Los Angeles (CHLA) for research purposes. Using clinical information obtained from follow-up visits of childhood cancer survivors, the database will focus on interventions to improve health status and health-related quality of life in childhood cancer survivors. This study allows for establishment and analyses of a research database for LIFE survivors by the investigators listed herein. Over the last three decades, there has been marked improvement in survival following childhood cancer, with 5-year survival rates now approaching 80%. However, the use of cancer therapy at an early age can result in complications that may not be apparent until years later as the child matures. These resulting complications, called late effects, are principally related to the specific therapy employed and the age of the child at the time the therapy was administered. Late effects may affect virtually every body system and substantially impair quality of life. As many as two-thirds of childhood cancer survivors develop at least one late effect as a result of treatment, and approximately one-third have a late effect classified as severe or life threatening.

The goal of this clinical trial is to conduct a comparative effectiveness trial that will evaluate two school-based interventions to improve adolescent sleep health: the standard Sleep Health Education (SHE) and a stepped care version of the Transdiagnostic Sleep and Circadian intervention (TS-C-STEP). The main questions it aims to answer \[is/are\]: * TS-C-STEP will yield superior outcomes relative to SHE at post-treatment and up to 12 months following treatment. * In this large and diverse sample, vulnerable subgroups (e.g. socioeconomically disadvantaged, racial, ethnic, rural, and youth with comorbid learning and/or mental health conditions) will experience greater benefits from TS-C-STEP compared to SHE on primary and secondary outcomes. Researchers will compare sleep quality to determine which intervention is most effective.

The goal of this clinical trial is to assess whether social-media style short-form health education videos can increase health care transition readiness, self-efficacy, emotional well-being, health literacy, and appointment attendance, compared with publicly available health education resources in adolescents with chronic illnesses. The main question it aims to answer is: -Hypothesize social media intervention will increase health care transition readiness, self-efficacy, emotional well-being, health literacy, and appointment attendance compared to publicly available health education website immediately post intervention and at 6 month follow up. Participants will be randomly assigned to one of the interventions and access the intervention for 20 minutes and complete 30-60 minutes of surveys.

The overall aim of this proposal is a confirmatory efficacy trial sufficiently powered and designed to test the hypothesis that improving the relationship between biological circadian timing and waketime, a novel modifiable target, improves depression outcomes in a subgroup of adolescents with depression and a misaligned relationship between biological circadian timing and waketime utilizing a cognitive-behavioral sleep intervention.

The current study seeks to build on previous research that demonstrates the efficacy of Acceptance and Commitment Therapy in combating stigma by investigating the feasibility and acceptability of a protocol to support Black adolescents and young adults in coping with race related stress. The study will consist of a small, purposeful, non-randomized sample (N = 30) of clients enrolled into a 10-session Acceptance and Commitment Therapy group. The group will be offered as part of regular clinical care at the Division of Adolescent and Young Adult Medicine. Three consecutive groups will be run with approximately 8-10 participants in each group over the next year.

The goal of this clinical trial is to develop and preliminarily test a culturally adapted suicide intervention specifically for black youth. The main question it aims to answer: -To evaluate the feasibility and acceptability of the group, as well as the preliminary efficacy of the group for decreasing suicidal thoughts and behaviors and increasing protective factors such as hope, positive ethnic identity, and family and peer support. Participants will be asked to attend 10-week group intervention and complete pre-treatment and post-treatment assessment measures.

This is an observational study in patients who require clinical anesthesia. The main purpose of this study is to understand whether there are differences in the cerebral blood flow, and oxygen metabolism affected by different types of anesthesia. Subjects who require clinical anesthesia for a clinical MRI and for whom the use of anesthetics for the exam are in clinical equipoise are asked to join the study. All eligible subjects will be asked to provide informed consent before participating in the study.

Retinoblastoma (RB) is a primary eye cancer that forms in the back of the eye of infants and toddlers. Traditionally, RB is diagnosed without a biopsy; tumor can only be studied once an eye has been surgically removed. Given this limitation, we use aqueous humor (AH), the clear fluid in the front of the eye to detect specific markers, or information, that comes from the tumor itself.

Chronic constipation is common in children with cystic fibrosis (CF), likely due to impaired chloride channel function that reduces intestinal secretions. Standard osmotic laxatives often provide inadequate relief in this population. Maralixibat is an ileal bile acid transporter inhibitor (IBATi) that increases the amount of bile acids reaching the colon. Bile acids can enhance intestinal secretion, reduce transit time, and soften stool. This study will evaluate whether Maralixibat improves stool consistency in children with CF who experience constipation. We will enroll 20 children with CF and constipation, defined as a Bristol Stool Scale score \<4 for at least one week while on a stable laxative regimen. Each participant will receive Maralixibat for two weeks in addition to their usual laxatives. Families will record stool consistency and ease of defecation before and during treatment. The primary objective is to determine whether Maralixibat improves stool consistency to a Bristol Stool Scale score \>4. The secondary objective is to assess changes in ease of defecation using standardized questionnaires.

Previous clinical trials in adults with acute respiratory distress syndrome (ARDS) have demonstrated that ventilator management choices can improve Intensive Care Unit (ICU) mortality and shorten time on mechanical ventilation. This study seeks to scale an established Clinical Decision Support (CDS) tool to facilitate dissemination and implementation of evidence-based research in mechanical ventilation of infants and children with pediatric ARDS (PARDS). This will be accomplished by using CDS tools developed and deployed in Children's Hospital Los Angeles (CHLA) which are based on the best available pediatric evidence, and are currently being used in an NHLBI funded single center randomized controlled trial (NCT03266016, PI: Khemani). Without CDS, there is significant variability in ventilator management of PARDS patients both between and within Pediatric ICUs (PICUs), but clinicians are willing to accept CDS recommendations. The CDS tool will be deployed in multiple PICUs, targeting enrollment of up to 180 children with PARDS. Study hypotheses: 1. The CDS tool in will be implementable in nearly all participating sites 2. There will be \> 80% compliance with CDS recommendations and 3. The investigators can implement automatic data capture and entry in many of the ICUs Once feasibility of this CDS tool is demonstrated, a multi-center validation study will be designed, which seeks to determine whether the CDS can result in a significant reduction in length of mechanical ventilation (LMV).

The goal of this clinical trial is to examine the initial feasibility, acceptability, and effectiveness of Crisis Interventions for Pediatric Providers - Autism version (CIPP-A) for providers serving autistic youth in outpatient settings. The main question aims to answer: * Assess whether CIPP-A is feasible and acceptable to providers in development behavioral pediatric clinics? * Assess whether CIPP-A shows initial effectiveness in increasing providers confidence in managing suicide risk in autistic youth? If there is a comparison group: Researchers will compare CIPP-A to general safety planning intervention (SPI) on feasibility, acceptability, and initial effectiveness. Participants will be randomized to receive training in SPI or CIPP-A and complete online surveys and interviews over 6-months to measure feasibility, acceptability, and initial effectiveness.

This is a Phase 3a, randomized, parallel-controlled trial designed to compare the early re-initiation of semaglutide, starting two weeks after sleeve gastrectomy, to standard care (no pharmacotherapy following surgery). The trial will involve 150 youth with severe obesity who have been on semaglutide 2.4 mg weekly for at least 3 months prior to surgery. Participants will be randomized to either (1) semaglutide 2.4 mg weekly or (2) standard care for 24 months. Primary, secondary, and tertiary outcomes will be assessed at multiple time points: 1-month, day of surgery, and 1-, 3-, 6-, 9-, 12-, 18-, and 24-months postoperatively. We hypothesize that early re-initiation of semaglutide will be safe, well-tolerated, and lead to greater improvements in obesity, cardiometabolic risk, and eating behaviors.

The goal of this clinical trial is to to utilize Virtual Reality during their interventional radiology procedure to help reduce any pain and anxiety experienced during the procedure in patients above the age of 8 undergoing interventional radiology procedures. The main questions it aims to answer are: * To determine if Virtual Reality is more effective than standard care for reducing pain and anxiety in children undergoing painful interventional radiology procedures. It is hypothesized that children in the Virtual Reality condition will experience reduced pain and anxiety compared to children receiving standard of care. * To evaluate caregiver's assessment of patient distress and their satisfaction with Virtual Reality compared to standard of care. It is hypothesized that caregiver satisfaction with the medical procedure will be significantly greater in the Virtual Reality group compared to the standard of care group. It is hypothesized that caregivers will perceive lower pain/anxiety when their child receives Virtual Reality compared to standard of care. Participants will complete pre and post surveys before and after interventional radiology procedures. Participants will use Virtual Reality headsets while undergoing procedure.

The goal of this clinical trial is to evaluate the Impact of Continuous Glucose Monitoring Academy Education Curriculum Versus Standard Care on Glycemic Outcomes for Youth With Type 2 Diabetes (T2D): * The first aim is to determine how feasible it is to adapt the Continuous Glucose Monitoring Academy curriculum to teach youth with T2D glucose management strategies. * The second aim is to evaluate the effects of the Continuous Glucose Monitoring Academy metrics. * The third aim is to explore the relationships between these metrics with diabetes distress, diabetes family responsibilities, and process metrics. Participants will join for a total of four weeks of education, followed by a six-month clinical review. They will have access to an online workbook and videos, and will participate in virtual sessions with a diabetes educator who will cover glucose management strategies in-depth. Participants will wear their preferred Continuous Glucose Monitoring system (Dexcom or FreeStyle Libre) provided via insurance and inserted at the baseline visit.

The goal of this randomized clinical trial is to compare the effects of a virtual education curriculum in blood glucose variation of youth with type 1 diabetes wearing continuous glucose monitoring (CGM) device. The main questions the study aims to answer are: * Do participants undertaking the proposed curriculum present improved glucose variation than participants of standard education? * Explore relationships between participant's glycemic outcomes with diabetes distress, diabetes family responsibilities, and number of hours of diabetes education. Participants in the intervention group will: * receive an interactive workbook with problem-based learning scenarios and video links about CGM and glucose management strategies. * participate in four in-depth online group sessions with diabetes care and education specialists * complete questionnaires three times: at the time of study enrollment, week 4 and 6 months. Participants in the comparison group will: * receive standard education provided to all patients at CHLA * complete questionnaires three times: at the time of study enrollment, week 4 and 6 months.

The goal of this pilot randomized controlled trial is to evaluate a self-concept intervention (Self-Concept Reinforcement for Early School Readiness (SCR4ESR)) in young African American children using experimental and mixed methods. SCR4ESR provides self-concept themed children's books and advice at health supervision visits of children enrolled at ages 2-4 years. The specific aims of the proposed project are to: 1. assess the feasibility and acceptability of SCR4ESR implementation among parents and providers, 2. evaluate the capacity of SCR4ESR to improve self-concept reinforcement and book-sharing behaviors in parents of young African American children, and 3) evaluate the capacity of SCR4ESR to improve behavioral health and literacy in young African American children. The interviews conducted in Aim 1 will guide refinement of the intervention tested in Aims 2 and 3. The qualitative assessment will be complemented by quantitative trial statistics (e.g., recruitment rate) that inform trial feasibility and acceptability. Finally, the mechanism by which SCR4ESR impacts the primary outcome, behavioral health, and the secondary outcome, literacy, will be evaluated by structural equation modeling. This project will inform the development and implementation of early childhood interventions that improve the health of African Americans.

The goal of this clinical trial is to learn if shared medical appointment is an acceptable way to deliver care to youth with type 2 diabetes. The main question\[s\] it aims to answer are: * Is shared medical appointments an acceptable care delivery model for this population? * Does shared medical appointment improve psychosocial outcomes for this population? Participants will attend quarterly clinic appointments and group activities and take surveys. Researchers will compare this intervention to standard of care.
