About Malignant Tumors Study
Malignant tumors are aggressive cell growths that invade nearby tissues and can spread to other parts of the body. Unlike benign tumors, which are non-cancerous and remain confined, malignant tumors present serious health risks and often create complex medical challenges. These tumors can develop in various organs, leading to a wide range of symptoms and significantly affecting patient well-being. Early detection through proactive screening is essential, as prompt treatment improves outcomes and enhances survival rates.
Hightower Clinical conducted malignant tumor clinical trials in Oklahoma City aimed to advance cancer care by focusing on biomarker analysis to guide treatment strategies. Participants underwent screenings to assess eligibility, received detailed study insights, and were supported throughout the process by expert healthcare professionals. The trials were offered at no cost to participants, including free study-related care, with compensation provided for time and travel.

About Atrial Fibrillation (AF) Study
Atrial Fibrillation (AF) is a common heart condition characterized by an irregular heart rhythm in the upper chambers (atria). Afib is one of the common types of arrythmias and present symptoms like fatigue, palpitations, difficulty in breathing, and dizziness.
Hightower Clinical conducted a study to evaluate the safety and effectiveness of the Amulet Left Atrial Appendage (LAA) occlusion device as an alternative to NOAC therapy in patients with non-valvular AF at increased risk for stroke. The goal was to provide insight into whether the device can be a safer and more effective long-term option for stroke prevention compared to NOACs.

Contributed to Improved Care for Patients with Heart Failure and CKD
Heart failure occurs when the heart can’t pump blood effectively, leading to symptoms like fatigue, shortness of breath, and swelling. Chronic kidney disease (CKD), a gradual loss of kidney function, often contributes to heart failure by increasing strain on the heart and disrupting fluid and blood pressure balance.
To better understand this connection, Hightower conducted a clinical trial focused on heart failure and impaired kidney function. The study evaluated the effects of a once-daily treatment added to standard care on reducing cardiovascular death and heart failure-related events.

Ulcerative Colitis - Inflammatory Bowel Disease
Ulcerative Colitis (UC) is a type of Inflammatory Bowel Disease (IBD) characterized by chronic inflammation in the colon and rectum. The diagnosis of UC primarily relies on colonoscopy results. It is more prevalent than Crohn’s disease, occurring three times more frequently. Ulcerative colitis (UC) affects approximately 1 million individuals (about the population of Delaware) in the United States.
Hightower conducted numerous clinical trials to explore potential treatments and research in Ulcerative Colitis. These trials focused on evaluating the safety and effectiveness of new drugs aimed at reducing the symptoms and colon inflammation of patients with moderate to severe UC and IBDIBD.

Know About Atopic Dermatitis Research Study
Atopic dermatitis, known as eczema, is a chronic inflammatory skin condition affecting millions worldwide. It causes dry, itchy, and inflamed patches of skin, disrupting sleep, impacting daily activities, and causing significant discomfort. While current treatments offer some relief, they can be ineffective for many.
We actively managed clinical trials for atopic dermatitis. One involved treating patients with moderate to severe atopic dermatitis for whom standard, approved medicated topical and systemic treatment options were inadequate. The second evaluated the efficacy and safety of a subcutaneous investigational drug.

Hightower’s Efforts in Basal Cell Carcinoma Prevention
Gorlin syndrome, or nevoid basal cell carcinoma syndrome, is a genetic condition that affects multiple parts of the body and increases the risk of both cancerous and noncancerous tumors. The most common cancer seen in this condition is basal cell carcinoma, a type of skin cancer that often begins to appear in adolescence or early adulthood.
To support patients with Gorlin syndrome, Hightower Clinical conducted a study to evaluate the safety and effectiveness of a topical treatment aimed at preventing new basal cell carcinomas from developing on the face of affected adults.
Past Study Focused on Preventing Facial Tumors in Gorlin Syndrome
Hightower Clinical conducted a study to support individuals with Gorlin syndrome by evaluating the safety and effectiveness of a topical treatment to prevent new facial basal cell carcinomas.

Innovative Clinical Study on Systemic Lupus Erythematosus
Systemic Lupus Erythematosus, or SLE, is a chronic autoimmune disease in which the body’s immune system mistakenly attacks its own tissues. This can lead to inflammation and damage to organs such as the skin, joints, kidneys, heart, and lungs. Symptoms often include fatigue, joint pain, skin rashes, and fever, and they can vary widely from person to person.
Hightower Clinical conducted studies to evaluate a new investigational therapy for patients with SLE who had already received standard care. The trials aimed to explore whether this therapy could help improve SLE symptoms and overall quality of life, while also contributing to a better understanding of the disease and potential future treatment options.

About Infant Development
Infant development is a crucial phase marked by rapid physical and cognitive changes. Healthy growth during the first few months of life lays the foundation for a child’s long-term well-being. Nutrition plays a key role, with essential vitamins and minerals like iron promoting optimal growth, brain development, and immune function. Monitoring infants’ growth helps ensure they are meeting developmental milestones and thriving during these formative months.
This 16-week study focused on evaluating the growth and tolerance of healthy term infants fed iron-fortified formula. Conducted across multiple centers, the trial followed FDA-established guidelines to assess whether the formula supports normal growth and development. The findings aimed to contribute valuable insights into infant nutrition and growth standards.
