Current literature suggests that addressing hypoxia and shifting anaerobic metabolism to aerobic metabolism could be a viable strategy to preventing post surgery tissue fibrosis (adhesions). (ASRM) (Awonuga AO) (Diamond MP) (Duron) (Valerie I. Shavell) Evitar™ is a proprietary aqueous formulation of naturally occurring amino acids-a SURGICEUTICAL.  In a randomized double blind randomized controlled study (NCT04250467) in laparoscopic myomectomies which included 'all-comer' patients, 93.3% of Evitar™ treated patients did not have any evidence of tissue fibrosis at any of the 23 anatomical sites within the abdominal cavity (p=.0411) at second look laparoscopy (SLL), as compared to 58.8% in the control. This despite 80% of patients in the Evitar™ arm had complex presentations known to be associated with high risk of fibrosis formation as compared to 40% of patients in the control arm. The study was powered to 90%, alpha .05 to detect a 70% difference. The clinical results were presented at the 2018 AAGL World Congress. Further, the mechanistic abstract  (Robertson et. al 2019) was also selected for presentation at the same conference.  The clinical manuscript has been submitted for publication.

Market: limited options - first Surgiceutical to successfully translate in-vitro work to a treatment for patients, expands usage

Post operative tissue fibrosis/scar tissue or adhesions are a major medical problem with no current viable solution for laparoscopic surgeries.  For surgeons, bands of scar tissue complicate entry in robotic or laparoscopic surgeries, complicate surgical planes and take significant time (up to 4 hours) to cut and take down (adhesiolysis) before completing the scheduled surgical procedure. It has been shown that 1 in 5 patients (20%) undergoing adhesiolysis suffer an accidental bowel injury.  For hospitals, extended OR time also reduces efficiency, decreases revenues and explains why in part, surgically induced tissue fibrosis or adhesions are the single largest cause of surgical compliations, and reduced operating margins (JAMA 2016). Tissue fibrosis complications also leads to reduced clinical outcomes, high hospital readmission rates, reduced quality of life for patients and medical lawsuits. It can lead to serious and societal expensive complications such infertility, intestinal obstruction and pelvic pain.

Reversing Hypoxia and Restoring Homeostasis May Prevent Adhesions

(Valerie I. Shavell)

Evitar™ addresses this unmet medical need by preventing tissue fibrosis as a result of abdominal and pelvic surgeries. It is easy to use in laparoscopic procedures. It is the First in Class surgiceutical approach that has shown in a double blinded randomized controlled study to safely and effectively prevent the absence of any scar tissue in over 90% of patients. This type of scarring occurs in after most surgical procedures and is a worldwide major concern for surgeons, patients and the health care system. (Menzies) (Koji Okabayashi) (Trew)


Medical devices based on untargeted mechanisms of action (e.g. “barrier”-type, colloid osmotic agent) currently serve the market for open surgery. However, market leaders Seprafilm® (Baxter) and Interceed® (Ethicon) are not adapted for or approved by the FDA for laparoscopic surgery, are known to extend mean operation time and difficult to handle.
