Lymph Leakage clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Efficacy of Lymphovenous Bypass in the Treatment of Extremity Lymphedema

Start date: April 1, 2023
Phase:
Study type: Observational

BACKGROUND: Lymphedema is a pathologic soft tissue swelling that arises secondary to disruption of the lymphatic system. Lymphedema affects approximately 250 million people worldwide and causes significant physical and psychological morbidity. There is no definitive treatment for lymphedema. Lymphovenous bypass - microsurgically anastomosing lymphatic channels and venules - has demonstrated promising results in the treatment of lymphedema. PURPOSE: The purpose of this study is to determine the efficacy of lymphovenous bypass in treating extremity lymphedema. METHODS: This is a prospective, single-arm, cohort study. Eligible patients between 18-70 years of age with extremity lymphedema will undergo lymphovenous bypass. The primary outcome measure will be extremity volume and the secondary outcome measure will be quality of life assessed by a validated assessment tool for lymphedema of the limbs (LYMQOL). Patients will be assessed preoperatively and at 3, 6, 9, and 12-months postoperatively. Each participant will serve as their own control. Primary and secondary outcome measures will be assessed with paired t-tests. With a sample size of 9 patients we will have at least 80% power to reject the null hypothesis assuming an alpha level of 0.01. To further increase the power and to account for patients lost to follow-up the investigators will target a patient recruitment of 20. The findings of this study will help further elucidate the role of lymphovenous bypass in the treatment of extremity lymphedema.
