Trial to Evaluate the Safety and Effectiveness of Treatment With COMS One Device in Subjects With Diabetic Foot Ulcers
Recruiting
The purpose of this clinical trial is to evaluate the safety and effectiveness of the treatment with the COMS One device in subjects with refractory diabetic foot ulcers (DFUs). The prospective randomized, double-blinded, sham-controlled trial is designed to demonstrate superiority of wound closure of the COMS One device to a sham-control device through 24 weeks post-application, when each is administered in conjunction with standard of care (SOC) in the treatment of DFUs.

Aesthetic Outcome of Tie-over Bolster Application in Surgical Wounds
Recruiting
When patients have surgery on the head and face, stitches are the standard way to close the wound. Wounds always result in a scar, but doctors are always looking for ways to reduce scarring. Several studies have been done to test ways to close wounds that reduce scarring. One idea is to reduce the tension around the cut. One way to reduce tension is to stitch a small piece of a special gauze over the top of the regular stitches. This procedure is called a "tie-over bolster dressing." As the name... Read More

Comparing Cooling and/or Compression Approaches of Limbs for Prevention of Chemotherapy-Induced Peripheral Neuropathy
Recruiting
This phase III trial compares the effect of 3 study approaches in preventing chemotherapy-induced peripheral neuropathy: 1) cryocompression, 2) continuous compression, and 3) low cyclic compression. Taxane chemotherapy drugs, such as paclitaxel or docetaxel, can cause a nerve disorder called peripheral neuropathy, which can cause numbness, tingling, or pain in the arms and legs. The 3 study approaches will use a device, called the Paxman Limb Cryocompression System, made of wraps that cool and/o... Read More

Chardonnay Marc and Vascular Response
Recruiting
This study aims to obtain data on the potential influence of Vine to Bar product(s) containing Chardonnay marc on cardiometabolic health. These initial studies will inform the design and timing of data collection for future dietary intervention trials that will examine the influence of Chardonnay marc intake on outcomes/biomarkers of both cardiometabolic health and the gut microbiome. This includes collecting data on the potential differences in response to the products based on the unique food... Read More

CArdiac REhabilitation for Building Exertional heArt Rate for Chronotropic Incompetence in Long COVID-19
Recruiting
The goal of this proof-of-concept clinical trial is to determine whether cardiac rehabilitation improves exercise capacity and chronotropic (heart rate) response to exercise among people with Long COVID. The study will include individuals with confirmed SARS-CoV-2 infection, symptoms not present prior to COVID-19 that are persistent for at least 3 months after acute infection ("Long COVID"), and who have reduced exercise capacity less than predicted and reduced heart rate response during cardiop...

Immunomodulatory Effects of Fasting in Healthy Adults
Recruiting
This is a clinical trial assessing the effects of fasting on the immune system in healthy adults. Immune profiling, gene expression profiling, and flow cytometry on peripheral blood mononuclear cells (PBMCs) will be performed and we hypothesize that a period of fasting will alter the immune system in healthy adults.

Tumescence in HNC Skin Graft Reconstruction
Recruiting
Our primary objective is to determine if the use of tumescence has a meaningful effect on STSG uptake at the recipient site. This is an important outcome because poor graft uptake results in the need for prolonged local wound care, additional clinic visits for patients and increased risk of infection. A prospective, randomized comparison of the tumescence to our current standard of care will allow us to definitively evaluate any benefits to this technique.
Tumescence is commonly used in the tre... Read More

This is an international phase III trial, with a Bayesian design, incorporating two sequential randomisations. It efficiently examines a series of questions that routinely arise in the sequencing of treatment. The study design has evolved from lengthy international consultation that has enabled us to build consensus over which questions arise from current knowledge and practice. It will enable potential randomisation for the majority of patients with inguinal lymph node metastases and will provi... Read More

Comparison of New SUREcore Biopsy of Needle to Standard of Care During Transperineal Prostate Biopsies
Recruiting
To study a novel biopsy needle system for performing transperineal prostate biopsy. Prostate biopsy remains the standard approach for prostate cancer detection. While pre-biopsy MRI allows for targeting of visible lesions, systemic or 'off target' samples are recommended due to the well-recognized risk of undegrading and under sampling with current commercially available needles. The SureCore plus single-use biopsy needle produces a more intact tissue core with a same caliber 18g needle with \~2... Read More

Kaiser Permanente houses over 6,000 physicians in southern California and it is also one of the largest research centers on the state. On its clinical trial division, Kaiser Permanente conducts clinical trials of almost every specialty funded by pharmaceutical companies, government, and foundations.
The Cedars-Sinai Medical Center located in Los Angeles is one of the largest research centers owned and operated by a private hospital in the United States. Focusing on biomedical, cancer, and heart research among other specialties, you can find almost any type of clinical trials for both health and non-healthy volunteers at the research division of Cedar-Sinai Medical Center.
There are around 100,000 clinical trials happening every year across the United States about almost every condition out there. While most clinical trials are testing drugs or medical devices there are also many behavioral and observational trials going on at any point in time. Many paid research studies are held at these California locations.
Clinical trials are incredibly important for making new medical and scientific discoveries, finding new and better methods for diagnosing medical conditions early, testing new interventions, and even developing safer and more effective surgical procedures.
In order for all these discoveries to me made available to the general population they need to go through years of rigorous testing both in healthy and non-healthy volunteers. During those years, medical professionals follow a protocol that has been previously approved by the FDA or other regulatory agency to test the effectiveness and safety of their discovery.
Other people choose to participate in a clinical trial because they feel it is a good way to contribute to the advancement of medical knowledge and that their participation can help many people in the future. The following lists of trials are broken down by condition, and to find a specific clinical trial in your area click through to clinicaltrials.gov.
