LYMPHA Procedure for the Prevention of Lymphedema After Axillary Lymphadenectomy
What this study is about
Lymphedema is a chronic, progressive, and debilitating condition that occurs with disruption or obstruction of the lymphatic system, which commonly occurs a result of breast cancer therapy. The purpose of this study is to determine if the use of a low risk lymphatic reconstruction procedure at the time of axillary lymph node dissection will reduce the risk of developing lymphedema.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Ages 18 to 75 years (inclusive)
- Patients undergoing unilateral or bilateral breast cancer related axillary lymphadenectomy
- Free of distant metastasis in preoperative screening
- Histology results of axillary lymph nodes could be either Negative or Positive
- Patients who undergo preoperative chemotherapy can be included
- Willingness and ability to provide written informed consent
- Willingness and ability to comply with all study procedures
Exclusion criteria
- Primary lymphedema of the affected upper limb
- Secondary lymphedema of the affected limb prior to the lymphadenectomy
- Radiotherapy at the axilla before the study / surgery
- Allergic reaction to porcine collagen or ICG
- Receiving radiation therapy to the involved nodal basin in a period less than 4 weeks after the surgery
- Concurrent participation in a clinical trial of any other investigational drug or therapy, regardless of indication, within 1 month before screening
- Other medical condition that could lead to limb edema, such as (but not limited to primary lymphedema or acute venous thrombosis
- Other medical condition that could result in symptoms overlapping those of lymphedema in the affected limb (e.g., pain, swelling, decreased range of motion)
- Either of the following, at the time of baseline evaluation: ipsilateral:contralateral limb volume ratio\>1.1 or R0 bioimpedance ratio \> 1.106 when the nondominant limb is at risk, and 1.134 when the dominant limb is at risk.
- Life expectancy \< 2 years for any reason
- Pregnancy or nursing
- Substance abuse (such as alcohol or drug abuse) within 6 months prior to screening
- Severe psychiatric disease
- Significant or chronic renal insufficiency (defined as serum creatinine \> 2.5 mg/dL or an estimated glomerular filtration rate \[eGFR\] \< 30 mL/min at screening) or requires dialytic support
- Hepatic dysfunction, defined as alanine transaminase (ALT) or aspartate transaminase (AST) levels \> 3 × upper limit of the normal range (ULN) and/or bilirubin level \> 2 × ULN at screening
- Absolute neutrophil count \< 1500 mm3 at screening
- Hemoglobin concentration \< 9 g/dL at screening
- Any reason (in addition to those listed above) that, in the opinion of the investigator, precludes full participation in the study
Where
- San Francisco, California
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
