Clinical Research in Houston, TX
Pushing the Boundaries of Medical Innovation

At CLS Health, we are dedicated to the advancement of medicine. We believe that clinical research is essential to improving people’s health and well-being. For over 12 years, our physicians have participated in clinical research trials to provide our patients with cutting-edge treatment options.
Our clinical trials are designed to precisely test the safety and effectiveness of new treatments. With a commitment to patient-centered care, these research studies are conducted within the comfort of our practice offices. We collaborate with a variety of reputable clinical research organizations to ensure the highest standards of ethics, patient safety, and scientific integrity. These partnerships allow us to bring innovative treatments to our patients and help shape the future of healthcare.
Participants undergo a thorough screening process to ensure the study is a good fit. Screening includes reviewing criteria such as age, medical history, previous treatments, and other health conditions.
Eligible participants meet with one of our highly trained research staff to review the study and ask any questions. Our team’s top priority is to ensure participants' rights, safety, and well-being are protected throughout the study. Each participant will review and sign an IRB-approved informed consent form before any study procedures begin.
There is no cost to participate in a clinical trial for services provided as part of the study. In many cases, the study sponsor also provides compensation for time and travel. All study-related details—including risks, benefits, responsibilities, compensation, and more—will be thoroughly discussed during the informed consent process.
Participation in a clinical trial is always voluntary, and participants may withdraw at any time without penalty or impact to their ongoing care with their physician or practitioner.
Open Studies
Researching Treatments for Hypothyroidism Care
Do you suffer from Hypothyroidism? Researchers are studying an investigational product to assess its effects on thyroid hormone levels and quality of life.

FSGS is a type of kidney disease that occurs when scar tissue develops on the parts of your kidneys that act as filters (the glomeruli). The scar tissue makes it more difficult for the filters to do their job. Instead of keeping essential proteins in your body, the injured filters allow these proteins to flow into the urine. This can lead to high levels of protein in your urine, a condition called proteinuria.
Podocytes are cells lining the kidney that, in their normal state, prevent proteinuria. Injury to, and loss of, podocytes is a central component of FSGS. Protecting podocytes from further injury, and stopping proteinuria, may help slow the progression of kidney disease and potentially prevent kidney failure.
What is the purpose of this trial?
Currently, there is no approved therapy in the US to treat Focal Segmental Glomerulosclerosis (FSGS). Advances in drug therapy are key to treating FSGS in its early stages and preventing further kidney damage. The TRACTION-2 Trial is testing an investigational medication (GFB-887) that has the potential to reduce the amount of protein in urine and preserve kidney function in patients with kidney disease. If you have FSGS, this trial may be an option for you.
Qualifications:
- 18 to 75 years of age
- Have been diagnosed or are being treated for FSGS
- Have high levels of protein in your urine (proteinuria)
Requirements:
Diagnosis based on documented biopsy or genetic testing and currently receiving ACE inhibitor or ARB for 3 months.
Diagnosed with OAB? Participate in a clinical study for a new wearable OAB device.
Qualifications:
- 18 years of age or older
- Diagnosed with Overactive Bladder
- Have an average of 11 urinary frequency events per day
- Have daily access to WiFi
Requirements:
Wearing an investigational device for 30 minutes 1 to 3 times per week in your home.
12-week study period
This study looks at different strengths of a potential new investigational vaccine against chickenpox (varicella). The study will look at how safe the study vaccine is and will also determine whether it works to help prevent chickenpox in children.
Why is this study important?
Chickenpox is a very contagious infection that can cause serious complications in children. Access to several chickenpox vaccines is important because vaccination is the only way to help protect children from chickenpox.
Qualifications:
- Your child may be able to take part if they:
- Are 12-15 months of age
- Are in good health
- Have received the first 3 doses (primary series) of a pneumococcal conjugate vaccine, a vaccine against infections caused by the Streptococcus pneumoniae bacteria, which cause ear, lung, and other infections.
Requirements:
If your child takes part, they will be in this study for about 6 months. Your child will need to:
Complete 3 study visits and 2 phone contacts for safety follow-up.
Receive the study vaccine or reference vaccine and 3 other approved vaccines that are part of routine vaccination schedules:
M-M-R II against measles, mumps, and rubella
Havrix against hepatitis A infection
Prevnar 13, a pneumococcal conjugate vaccine, against infections caused by the Streptococcus pneumoniae bacteria, which cause ear, lung, and other infections
Have 1 blood sample collected about 6 weeks after vaccination.
Systemic Lupus Erythematosus (SLE), also known as “lupus,” is an autoimmune disease that affects multiple organ systems and is unpredictable in disease severity, with periods of illness or flares alternating with periods of remission. The presentation of lupus can affect many different parts of the body but frequently involves the joints, skin, kidneys, blood cells, and mucus membranes (the lining of the mouth, nose, throat, stomach, and intestines) which can result in symptoms such swollen joints, rash, foamy urine, changes in red or white blood cells, and oral ulcers, among others. Disease prevalence is approximately 1 in 1,000 individuals overall but varies with race and ethnicity.
What is the purpose of this trial?
Most therapies used to treat SLE are only partially effective and have considerable toxicity. The purpose of the study is to investigate if the investigational product, BIIB059, can reduce disease activity and inflammation in people with active SLE compared to a placebo. BIIB059 is a type of antibody that has been developed to target certain cells that are thought to play a role in the development of lupus. It is hoped the study drug can improve symptoms in people with SLE.
Qualifications:
- Participants must be at least 18 years of age
- Have been diagnosed with moderate-to-severe SLE for at least 6 months
- Are currently taking SLE medication
Requirements:
You will receive an investigational product via injections under the skin every month.
Visits will last about a year and a half and include around 22 visits to the study site.
