Prospective Evaluation of a Surgical Solution for Breast Cancer-Associated Lymphedema
Not Recruiting
Trial ID: NCT02734979
Purpose
To investigate whether addition of the Biobridge scaffold to the standard surgery for
vascularized lymph node transfer will improve the outcome of surgical treatment in lymphedema
of the upper arm.

Eligibility
Inclusion Criteria:
The subject must be a breast cancer survivor, at least three years beyond completion of
cancer therapy, free of clinical disease, and eligible for surgical intervention.
- Ages 18 to 75 years (inclusive).
- Swelling of 1 limb that is not completely reversed by elevation or compression
- Stage II or greater lymphedema at screening, based on the International Society of
Lymphology (ISL) staging system
- Completion of a full course of complete decongestive therapy (CDT), according to ISL
guidelines at least 8 weeks prior to screening, including use of compression garments
for at least 8 weeks without change in regimen
- Willingness to maintain a stable regimen of self-care, with consistent use of
compression garments from screening through the entire study duration (through the
safety follow-up visit). Self-bandaging, use of nighttime compression garments, and
intermittent pneumatic compression devices are allowed, but the procedures and
regimens must remain consistent from screening though the entire study duration.
- Two consecutive measurements of limb volume (LV) in the affected limb taken at least 1
day apart during the screening period must be within 10% of each other. A maximum of 3
measurements can be taken. Affected limb volume ratio >20% (affected limb compared to
unaffected limb); volume measurements will be performed and volume ratio will be
calculated at S1 and S2 visit.
- Evidence of abnormal bioimpedance ratio, if feasible based upon unilateral disease:
L-Dex >10 units; bioimpedance performed at S1 and S1
- Willingness and ability to understand and the willingness to sign a written informed
consent form document
- Willingness and ability to comply with all study procedures, including measurement of
skin thickness using skin calipers.
- Participants must have NED, completed breast cancer therapy 3 years prior to
enrollment.
- ECOG 0- 2
Exclusion Criteria:
- Edema arising from increased capillary filtration will be excluded.
- Inability to safely undergo general anesthesia and/or perioperative care related to
vascularized lymph node transfer
- Concurrent participation in a clinical trial of any other investigational drug or
therapy, regardless of indication, within 1 month before screening or 5 times the
drug's half-life, whichever is longer
- Recent initiation of (≤8 weeks), or intention to initiate, CDPT or maintenance
physiotherapy for lymphedema at any time during the duration of the study
- Other medical condition that could lead to acute limb edema, such as (but not limited
to) 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)
- History of clotting disorder (hypercoagulable state)
- Chronic (persistent) infection in the affected limb
- Any other infection (unrelated to lymphedema) within 1 month prior to screening
- Current evidence of malignancy or any high risk for breast cancer recurrence (Stage
III or IV, ER/PR/HER-2 negative (triple negative) cancer , locally advanced disease,
inflammatory breast cancer, > 3 positive axillary lymph nodes, extracapsular nodal
extension, invasive micropapillary breast carcinoma, or if performed, patients with a
high risk of recurrence based on multi-gene signatures, e.g. BRCA1, BRCA 2, Oncotype
DX (high risk recurrence score) or Mammaprint (poor risk signature)
- Currently receiving chemotherapy or radiation therapy
- Life expectancy < 2 years for any reason
- Pregnancy or nursing
- Substance abuse (such as alcohol or drug abuse) within 6 months prior to screening
- 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
- Known sensitivity to porcine products
- Any reason (in addition to those listed above) that, in the opinion of the
investigator, precludes full participation in the study
