Prophylactic and Therapeutic DLI-X for Leukemia Relapse After HCT

The primary objective of this proposal is to conduct the first-in-human randomized clinical trial evaluating prophylactic DLI-X (pro-DLI-X) for relapse prevention following matched sibling donor (MSD) or haploidentical (haplo) hematopoietic cell transplantation (HCT) in patients with hematologic malignancies. Additionally, the study aims to assess the safety and efficacy of therapeutic DLI-X (t-DLI-X) compared to t-DLI alone in patients with minimal residual disease (MRD+) or overt relapse post-alloHCT. For patients with CD19-positive lymphoid malignancies, the study will incorporate blinatumomab, while those with myeloid or CD19-negative lymphoid malignancies will receive t-DLI-X or t-DLI alone. We hypothesize that both pro-DLI-X and t-DLI-X, with or without blinatumomab, will demonstrate safety and superior efficacy by enhancing graft-versus-leukemia (GvL) effects mediated by natural killer (NK) cells, γδ T cells, and CD8+ T cells, while maintaining manageable and treatment-responsive graft-versus-host disease (GvHD).

The Effect of Semantic Support on Word Learning

The goal of this clinical trial is to compare word learning outcomes in late talking toddlers who are taught different types of words. The main question it aims to answer is if teaching words that come from categories that children already know (e.g., animals) will aid overall word learning. Children will take part in the Vocabulary Acquisition and Usage for Late Talkers (VAULT) word learning treatment and be taught words from more familiar or less familiar categories to see which group learns more words overall.

GLP-1 RA Plus SOC Treatment in First-line, Metastatic Pancreatic, Colorectal, or Hepatocellular Cancer

There is a growing number of patients diagnosed with gastrointestinal cancers who are also simultaneously being treated with GLP-1 Receptor Agonists (RA)s. To date, no clinical trial data exists to establish safety and/or feasibility with use of GLP-1 RAs during chemotherapy in the metastatic setting. The goal of this clinical trial is to evaluate the safety, tolerability, preliminary efficacy, and correlative analyses of combining GLP-1 RAs with standard chemotherapy in patients with metastatic pancreatic, colorectal, or hepatocellular cancers in the first-line setting.

VEDA Study (DHEA vs Estradiol)

This study is being done to compare two vaginal treatments, vaginal estrogen and vaginal DHEA, that are used to treat vaginal and urinary symptoms related to menopause. These symptoms may include vaginal dryness, discomfort, painful intercourse, or urinary problems and can affect quality of life and sexual health. Women who choose to participate will be randomly assigned to use one of the two treatments for a set period of time. Participants will complete questionnaires about their symptoms and sexual health and have simple vaginal testing at the beginning and end of the study. The goal of this research is to better understand how these treatments affect vaginal health and sexual function so healthcare providers can make informed treatment decisions and improve care for postmenopausal women.

Social Optimization Study

This study tests whether clinical interventions to optimize support receptivity lead to improvements in social integration and quality of life (QOL) amongst long-term lung cancer survivors. The feasibility and acceptability of the intervention and assessment procedures will be examined. Thirty long-term lung cancer survivors will be randomized to a support receptivity intervention or an attention-control condition. Our intervention draws on cognitive behavioral therapy (CBT) strategies to reduce social anxiety, improve social awareness, and promote social integration. We will use two novel in vivo sampling methods using a mobile phone platform to assess social engagement and QOL improvements: 1) recording via the Electronically Activated Recorder to capture daily social interactions, and 2) repeated self-report sampling where participants answer questions about their social engagement experiences via their personal cell phone.

Exercise as an Immune Adjuvant for Allogeneic Cell Therapies

This study aims to improve the treatment of blood cancer by using exercise to collect healthier immune cells from donors. Allogeneic adoptive cell therapy is a treatment where immune cells from a healthy donor are given to a cancer patient, usually to help prevent or treat cancer relapse after a stem cell transplant. These donor cells can either be directly infused into the patient or grown in a lab to create more specialized immune cells that target and kill cancer. While this therapy has been helpful for many patients, there is a need to make it more effective for a larger group and reduce side effects like graft-versus-host disease (GvHD), where the donor's immune cells attack the patient's healthy tissue. This Early Phase 1 trial will test whether exercise can help produce better immune cells from donors. The investigators will recruit healthy participants for three study groups: 1. Exercise Group: Participants will complete a 20-minute cycling exercise session. The investigators will collect blood samples before, during, and after exercise to study the number and quality of immune cells. The investigators will also use the collected cells to create immune therapies and test their ability to kill cancer cells in the lab and control cancer growth in mice. 2. Exercise and Beta Blocker Group: In this group, participants will complete up to five cycling sessions, with at least a week between each session. Before each session, participants will take either a placebo or a drug (beta blocker) that blocks stress hormones like adrenaline. The investigators will collect blood samples before and during exercise to see how blocking these hormones changes the effect of exercise on immune cells. 3. Isoproterenol Group: Participants in this group will receive a 20-minute infusion of isoproterenol, a drug that mimics the effects of adrenaline. The investigators will collect blood samples before, during, and after the infusion to see if the drug causes similar immune changes to those caused by exercise. Participants can join one, two, or all three groups. This research will help understand whether exercise can improve immune cell therapies for treating blood cancer and reduce the risk of GvHD, making these treatments safer and more effective.

Human Papillomavirus (HPV) Self-Sampling Options to Promote Equity

This study is testing a new way to help people who are unhoused get screened for cervical cancer. Cervical cancer can often be prevented if it is found early. Many people who lack stable housing usually do not receive regular screenings. Through this project, the investigators will bring screening to community locations in Tucson, Arizona, using a mobile health unit (MHU) from the University of Arizona (UA) and El Rio Health. At these sites, participants will receive easy-to-understand education about cervical cancer, learn how to collect their own sample for human papillomavirus (HPV) testing, and get follow-up care if needed. The study has two goals: * First, the investigators will see if this community-based approach helps more people complete cervical cancer screening. * Second, the investigators will ask participants, clinicians, and outreach staff for their opinions about the program and its practicality and acceptability. By testing this approach, the investigators hope to find a way to make cervical cancer screening more accessible and effective for unhoused individuals.

Radiation Combined With BIspecific T-Cell Engager in DLL3 Expressing Tumors

Phase I study to examine safety of the addition of concurrent tarlatamab with standard palliative and consolidative RT regimens , with a main cohort of N=20-24 patients with extracranial anatomic radiation sites. I) After lead in of 10 patients demonstrating safety of treatment, allow for expansion to cranial sites of disease (N=6-10) with continued enrollment in main cohort II) If toxicity criteria is not met in concurrent RT tarlatamab cohort, we will continue with sequential RT, either A) delivered within 7 days prior to cycle 1 day 1, or B) delivered during cycle 1 -2 but with pre- and post-RT washout of 7 days with no drug during RT, to examine safety in a temporally spaced setting. III) If sequential tarlatamab and radiation is not deemed safe, we would allow for continued enrollment to assess efficacy of drug sans radiation treatment, enriching for tumors not of small cell lung cancer histology and allowing for patients without sites amenable to RT. A nested phase II study will attempt to assess for ORR and safety of study intervention amongst tumors not of small cell lung cancer histology.

Adaptive Symptom Self-Management Immunotherapy Study

The use of immune checkpoint inhibitors (ICIs), alone or in combination with other cancer treatments is increasing dramatically with immune-related adverse events (irAEs) common (90%) during ICI treatment. Most irAEs are symptomatic and symptom self-management with timely reporting of moderate or severe symptoms to health care providers (HCPs) may reduce irAE severity by early recognition and management, resulting in fewer treatment interruptions and unscheduled health services.

Stratafix vs. PDS (Fascial Closure RCT)

This proposed prospective, randomized, single-blinded controlled trial will directly compare Stratafix anti-microbial barbed sutures and standard PDS sutures for fascial closure at the time of Cesarean delivery. Primary outcomes will include postoperative pain scores at 24 hours, 48 hours, and two weeks postpartum (both total pain and right-sided abdominal pain commonly associated with the knot from traditional fascial closure), as well as total opioid consumption (morphine milligram equivalents) for the first 48 hours. Secondary outcomes will include length of hospital stay, wound complications (e.g., infection, dehiscence), patient satisfaction measured per the standardized surgical satisfaction questionnaire (SSQ-8), time required for fascial closure (minutes from start to end of fascial closure), and surgical site infections. The hypothesis is that among women undergoing primary Cesarean delivery, fascial closure with barbed suture (Stratafix) will result in lower postoperative pain scores and reduced opioid (narcotic) consumption within the first 48 hours after surgery compared to closure with traditional monofilament suture (PDS).

Impact of Continuous Glucose Monitoring and Education Intervention on Glycemic Control and Behavioral Changes in Pre-Diabetic Adolescents

Prediabetes is a condition wherein blood sugar levels are elevated but not sufficiently high enough to diagnose type 2 diabetes mellitus (T2D). Prediabetes is a critical risk factor for the development of T2D in pediatric populations. This progression can occur over a short period of time, limiting the efficacy and impact of existing interventions and recommendations targeting this population. There is growing evidence on the use of continuous glucose monitors (CGMs) in adult prediabetic populations to prevent the development of T2D, though this intervention has not been thoroughly investigated in pediatric populations. The investigators are proposing a pilot study of 25 prediabetic adolescents enrolled in a 20-week study. For the initial 10 weeks of the study, the participants will go without CGMs and undergo clinically recommended education on their condition as standard of care. In the 10 weeks following, participants will be given a CGM to wear and instructions on its use. Surveys will be issued to all participants over the entirety of the study to follow behaviors surrounding food and physical activity.

A Nutrition & Exercise Prehabilitation Intervention on Inflammatory Biomarkers in AI Cancer Patients

The purpose of this study is to assess the feasibility of a prehab intervention among American Indian (AI) patients diagnosed with cancer and measure inflammatory biomarkers to evaluate the preliminary impact of the trial intervention. The central hypothesis is that this community-informed prehab intervention will demonstrate feasibility, patient acceptability, and modulation of host and tumor-microenvironment inflammatory biomarkers. Aim 1: Implement the prehab translational clinical trial for AI patients with cancer scheduled for treatment. Aim 2 Measure host and tumor-microenvironment (TME) biomarkers using paired serum and tissue samples to compare baseline and post-intervention levels of expression. Serum markers include CRP, IL-6, IL-10, TNFa, IGF-1, VEGF, complete blood count (CBC) with differential, comprehensive metabolic panel (CMP), and prealbumin. Tissue markers include Ki67, insulin receptor, TNFa, NFKB, NOS2, and cleaved caspase 3. Aim 3: (optional exploratory aim): Assess differential expression of inflammatory genes in the TME using tumor tissue samples to compare baseline and post-intervention levels of expression. This will be done with a panel that analyzes inflammatory genes only.

The Impact of Exercise on the Tumor Microenvironment in Patients With Lung Cancer

There is increased interest and knowledge about the lung cancer tumor microenvironment (TME). Investigators hypothesize that patients with better baseline physiologic health will have better post-operative outcomes and that strenuous exercise will alter the TME and genetic make-up of the tumor, improving the tumor immune response. Investigators aim to identify the peri-operative and clinical outcomes that differ based on pre-operative VO2max, HRV and resting heart rate following resection of early-stage lung cancer. The physiologic states that are individual and measurable with wearable devices include but are not limited to VO2max, heart rate variability (HRV), and average resting heart rate. Investgators hypothesize that a patient's pre-operative physiologic function with higher VO2max, HRV and lower resting heart rate will be associated with improved peri-operative and post-operative outcomes. Second, investigators will compare alterations in TME based on targeted pre-operative exercise (60-80% of their VO2 max for 75min/week x2 weeks) compared to normal activity adults following resection of early-stage lung cancer. Investigators hypothesize that strenuous exercise in the pre-operative period will impact the TME by increasing levels of cytokines.

SUV PDL1/PD1 in Sun Damaged & Sun Protected Human Skin of Participants

The purpose of this research study is to look at how the proteins and genes in people's skin change when they're exposed to simulated sunlight. The researchers want to see if there are differences between people who've had skin cancer and those who haven't despite having a similar type of skin and history of sun exposure. Since this study is designed to simulate sun exposure to small areas of skin, mild to moderate sunburn and tanned spots at the site of the simulated sunlight exposure is a risk. In addition to simulated sun exposure, patients will also have four 6 mm punch skin biopsies performed. Brief discomfort may be felt when the local painkiller (lidocaine) is injected prior to skin biopsies; however, it is usually minimal. Participation in the study involves 4 visits to the clinic over the course of 4 weeks. Each visit will take no longer than 90 minutes.

Endotype DIrected Treatment for OSA in Down Syndrome

Down syndrome is the most common genetic cause of intellectual disability. People with Down syndrome often have obstructive sleep apnea (OSA), a condition where people have difficulties with breathing while asleep. OSA can lead to poor sleep, worse quality of life, behavior problems and more difficulties with thinking ("cognitive impairment"). Current treatments for OSA in people with Down syndrome are not very effective or require surgery. The combination of 2 medications, atomoxetine and oxybutynin ("ato-oxy") is a promising treatment for OSA in people with Down syndrome, but ato-oxy does not work for everyone with Down syndrome. Similarly, oxygen is effective for OSA in some people, but does not work for everyone. This study will evaluate the use a precision medicine approach to increase the effectiveness of OSA treatment in people with Down syndrome. The study will compare two groups. In the first group, everyone will be treated with ato-oxy. In the second group, a precision medicine approach will be used to assign participants to either ato-oxy or oxygen therapy, based on the specific reasons they have OSA. The research team will enroll 200 children (age 6-17 years old) and adults with Down syndrome and OSA from five sites across the country. Half of participants will randomly receive ato-oxy while the other will receive either oxygen or ato-oxy dependent upon which treatment would be expected to work better for them. The research team will measure OSA severity, quality of life, behavior and cognition at the start of the study and after 12 months of treatment for every participant. The study will also track any treatment side effects for each treatment group.

Elucidating the Central Mechanisms of Action for Green Light Therapy in Managing Chronic Pain

Investigators have previously shown that specific colors of light can alter nociception. Green light emitting diode exposure (GLED) provides long-lasting antinociception in rodents, through the visual system. No adverse effects were noted, and motor performance was not impaired. Investigator clinical trials have shown GLED is also effective in decreasing pain intensity of fibromyalgia patients and decreasing the number of headache-days per month in migraine patients. However, investigators do not yet understand the mechanisms by which GLED reduces pain. Understanding the mechanisms of action of GLED will provide additional support for using light therapy as both a treatment and as a possible diagnostic tool. While investigators do not fully understand the mechanisms of action of GLED, investigators do know that it is centrally mediated. To better elucidate the mechanism of action for GLED, investigators propose a single-blinded randomized placebo-controlled clinical trial to elucidate the central mechanism(s) of action that GLED therapy has in improving fibromyalgia pain, conducted by a team with a successful record of collaboration. Investigator's hypothesis is that GLED decreases neuroinflammation leading to modulation of the signaling in the ascending and descending pain pathways.
