Eligibility Criteria

18 Years - undefined (Adult, Older Adult)FemaleAccepts Healthy Volunteers

Inclusion Criteria:

  1. Female subjects aged 18 years and older
  2. Female subjects of childbearing potential must have a negative urine or blood pregnancy test at screening and baseline.
  3. Female subjects of childbearing potential must agree to use ONE of the following birth control methods throughout the study:

    • abstinence
    • condom with spermicide
    • diaphragm with spermicide
    • Hormonal contraceptive
    • intra-uterine device

    Non-childbearing confirmed by prior documentation of at least one of the following:

    • postmenopausal
    • surgically sterilized
  4. Subjects undergoing a breast surgery procedure with bilateral anchor incisions
  5. Signed informed consent form

Exclusion Criteria:

  1. Subjects with breast implants or history of breast implants
  2. Subjects undergoing breast surgery requiring breast implants
  3. Subjects requiring nipple grafting using any technique
  4. Subjects with a history of infection in the past 6 months in the intended area of incision
  5. Subjects with breast tattoos in the intended area of the incision
  6. Subjects with known skin sensitivity to Tegaderm™
  7. Subjects with a history of keloids
  8. Known conditions of collagen vascular diseases
  9. Subjects with clinically significant medical conditions as determined by the Investigator, which would impair wound healing including renal, hepatic, hematologic, neurologic or autoimmune disease. Examples include but are not limited to:

    1. Renal insufficiency as an estimated GFR, which is < 30 mL/min/1.7m2
    2. Abnormal blood biochemistry defined as 3 times that of the upper limit of the normal range
    3. Hepatic insufficiency defined as total bilirubin > 2 mg/dL or serum albumin < 25 g/L
    4. Hemoglobin < 9 g/dL
    5. Hematocrit < 30%
    6. Platelet count < 100,000 μL
  10. Any history within the last 5 years or the presence of any active systemic cancer (with the exception of non-melanoma skin cancer)
  11. Current treatment with systemic corticosteroids (>15 mg/day). Washout period is 30 days prior to screening
  12. Current treatment with biologic immunosuppressive agents or chemotherapeutic agents. Wash out period for short term immunosuppressive agents is 14 days prior to screening
  13. Previous history of radiation therapy to the chest
  14. Known inability to complete required study visits during study participation
  15. A psychiatric condition (e.g., suicidal ideation), chronic alcohol consumption, or drug abuse problem determined from the subject's medical history, which, in the opinion of the Investigator, may pose a threat to subject compliance
  16. Use of any investigational drug or therapy within the 28 days prior to screening
  17. History of previous breast surgeries in the area where the incisions are to be made
  18. Currently pregnant, pregnant during the 6 months prior to screening, lactating, or breastfeeding
  19. Any other factor, which may, in the opinion of the Investigator, compromise participation and follow-up in the study
  20. Any areolar abnormalities that are deemed clinically significant by the Investigator

Arm Description

Within-subject comparison of Granexin® Gel versus vehicle gel (placebo). Granexin® gel 100 μM will be applied four times over three days: twice during surgery, 24 hours after surgery and 48 hours after surgery. Granexin® will be applied on the right or left breast according to a randomization list.

Outcomes

Primary Outcome Measures

Change in scar severity at Month 12
Assessed using the Patient and Observer Scar Assessment Scale (POSAS). The POSAS has a rage from 6 to 60 with higher scores indicating worse outcomes. One scale will be used for each segment of the scar. The score from each segment will be combined into one score.

Secondary Outcome Measures

Change in scar severity at Month 6, Month 9 and Month 12
Assessed using the Scar Cosmesis Assessment and Rating (SCAR) Scale. The SCAR scale has a range of 0 (best possible scar) to 15 (worst possible scar).
Change in scar severity at Month 9
Assessed using the Patient and Observer Scar Assessment Scale (POSAS). The POSAS has a range from 6 to 60 with higher scores indicating worse outcomes. One scale will be used for each segment of the scar. The score from each segment will be combined into one score.
Proportion of subjects with incision healing complications
Investigator's assessment of incision healing complications
Proportion of subjects with incision infection
