Breakthrough Medication
Down syndrome (DS), the most common genetic cause of intellectual disability, is associated with widespread organ dysfunction, including abnormalities in the autonomic nervous system (ANS). The ANS regulates critical functions such as heart rate (HR) and blood pressure (BP), both essential for maintaining homeostasis and supporting physical activity. Individuals with DS often exhibit blunted HR responses to exercise-typically \~30 beats per minute below expected levels-suggesting reduced sympathetic nervous system (SNS) activity. The SNS governs rapid changes in HR and BP during stress by releasing catecholamines: epinephrine (from the adrenal medulla) and norepinephrine (from sympathetic nerve endings). Despite its importance, SNS function has not been comprehensively assessed among individuals with DS. This study addresses a critical knowledge gap by evaluating SNS responses to physiological stressors in individuals with DS. The investigators will measure beat-to-beat HR and BP, along with plasma catecholamine levels, in response to sympathetic activation, comparing individuals with DS to age- and sex-matched controls. Understanding the mechanisms of SNS dysfunction in DS is vital, as it likely underlies reduced exercise capacity and contributes to broader clinical challenges. These insights may guide targeted interventions to improve cardiovascular function, physical capacity, and overall quality of life in this understudied population.

This phase III trial evaluates whether a web-based intervention called Current Together after Cancer (CTAC) works to increase the number of patients with surgically removed (resected) colorectal cancer who receive surveillance care that aligns with current guidelines (guideline-concordant). Surveillance care after resection of colorectal cancer is critical to detect potentially curable return of disease (recurrence), yet up to 60% of colorectal cancer survivors fail to receive surveillance. This may be due to a lack of knowledge about the purpose of surveillance care and the risks of cancer recurrence, or a lack of confidence for managing surveillance care. The CTAC intervention is an online education intervention designed to improve patients' knowledge about surveillance and their self-efficacy for managing surveillance, and to promote effective communication with supporters and supporter engagement in patients' surveillance in a way that is aligned with each patient's preferences. By increasing a patient's knowledge, self-efficacy, and satisfaction with their supporter's engagement in their care, the CTAC intervention may increase the number of patients who receive guideline-concordant surveillance care after resection of colorectal cancer.

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.

What if midlife women, who are inherently at an increased risk for future cardiometabolic disease due to transitioning into menopause, had access to a suite of evidence-based health interventions? Could these interventions reduce menopause-related inflammation, restore a healthier cardiometabolic profile, reverse epigenetic aging, and reduce bothersome menopausal symptoms? The ultimate goal of this work is to attenuate future disease and enhance women's quality of life, extend healthspan and increase productivity.

This randomized phase III trial studies combination chemotherapy with blinatumomab to see how well it works compared to induction chemotherapy alone in treating patients with newly diagnosed breakpoint cluster region (BCR)-c-abl oncogene 1, non-receptor tyrosine kinase (ABL)-negative B lineage acute lymphoblastic leukemia. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as blinatumomab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. It is not yet known whether combination chemotherapy is more effective with or without blinatumomab in treating newly diagnosed acute lymphoblastic leukemia.

The menopause transition is associated with a decrease in artery health and an increased risk for weight gain in storing fat in the stomach area which may increase the risk for heart disease. The purpose of this research is to study how the decrease in estrogen at menopause changes artery health and fat gain, and risk of disease in women as they age. The first aim in this study will determine whether short term and long term low estrogen levels in premenopausal women decreases artery function and whether this is related to an increase in fat in the stomach area. The second aim will determine whether the changes in artery health and body fat are related to changes in a pathway that breaks down an important amino acid called tryptophan. This pathway is thought to play a role in regulating the aging process. Therefore, the investigators will determine whether the decrease in artery health and the increase in body fat in the stomach region with low estrogen is related to changes in this pathway in the blood, in vascular cells and fat tissue. Because estrogen levels fluctuate in premenopausal women, the investigators will use an approach (intervention) that controls estrogen levels to address these aims. The investigators will use a medication that is typically used to treat endometriosis or uterine fibroids to lower estrogen levels and an estrogen patch to increase estrogen in some women. Some women will receive a patch that has no estrogen (called a placebo patch). The intervention period will be 20 weeks. The study will provide us with new knowledge on how low estrogen with menopause affects artery health and fat gain estrogen.

Frequently Asked Questions

How much do clinical trials in Colorado 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 Colorado 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 Colorado 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 Colorado 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 Colorado 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 Colorado?

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 Colorado?

Most recently, we added Adalimumab + Verapamil for Type 1 Diabetes, LevoCept for Birth Control and Sympathetic Nervous System Function for Down Syndrome to the Power online platform.
