Randomized, Controlled Trial Comparing Separation of Components Repair With Retrorectus Gentrix™ Surgical Matrix Versus Biological or Prosthetic Mesh for Open Ventral Hernia Repair

The hypothesis for this study is complex incisional hernia repair using the separation of
components technique reinforced with retrorectus placement of Gentrix™ Surgical Matrix will
lead to fewer incisional hernia recurrences and fewer wound complications compared to the
same incisional hernia repair techniques reinforced with other prosthetic or
biologically-derived mesh.

Biological and prosthetic mesh products are extensively used in hernia repairs. However, they
also have their limitations. Potential complications associated with prosthetic mesh for
hernia repairs include: adverse reactions to the mesh, mesh erosion, stricture formation,
adhesions resulting in bowel obstruction, enterocutaneous fistulas, injuries to nearby
organs, nerves or blood vessels, infection, chronic pain and hernia recurrence. Potential
complications associated with biological mesh include: adverse inflammatory response, laxity,
eventration, and recurrent herniation. This study is a two-arm, randomized, controlled trial
comparing separation of components repair with retrorectus Gentrix™ Surgical Matrix versus
biological or prosthetic mesh for open ventral hernia repair.

Inclusion Criteria:

- Male and female patients ≥ 18 years old.

- American Society of Anesthesiologists (ASA) physical status classification of I, II,
III or IV.

- Able to provide informed consent in English or Spanish.

- Stated willingness to comply with all study procedures and availability for the
duration of the study.

- Body Mass Index (BMI) =< 45.

- Incisional hernia from a midline incision ≥ 4 cm in greatest diameter, or any
recurrent incisional hernia.

Exclusion Criteria:

- Any other type of ventral hernia, such as umbilical, epigastric or Spigelian hernia.

- Pregnant, breastfeeding, or unwilling to practice birth control during participation
in the study, if applicable.

- Allergy or hypersensitivity to materials in porcine-based study products, biological
or prosthetic meshes, or personal preference.

- Contraindications to general anesthesia.

- Patient undergoing any emergency surgery prior to treatment.

- Severe comorbid conditions likely to limit survival to less than 3 years in the
opinion of the Investigator.

- Have abdominal loss of domain such that the operation would be impractical or would
adversely affect respiratory or cardiovascular function to an unacceptable degree in
the opinion of the Investigator.

- Inability to close the fascia primarily with abdominal wall mobilization or component
separation; confirmed intra-operatively.

- History of malignancy within the past 5 years except for non-melanoma skin cancer.

- Known active malignancy present and/or had chemotherapy 12 weeks prior to screening or
planned chemotherapy within 12 weeks of treatment with exception of basal cell
carcinoma, squamous cell carcinoma, or prostate cancer in situ.

- Cirrhosis with or without ascites.

- Received high dose steroids (>/=100mg of prednisone) within the past 6 weeks of
screening.

- Uncontrolled diabetes (i.e. known HbA1C value > 7% within the prior 6 weeks of the
Screening Visit).

- History of drug addiction (recreational drugs, prescription drugs or alcohol) that in
the Investigator's opinion may interfere with protocol assessments and/or the
subject's ability to complete the required follow up.

- Serious or active medical or psychiatric condition which, in the opinion of the
Investigator, may interfere with treatment, assessment, or compliance with the
protocol.

- Suspected presence of enterocutaneous fistula.

- Planned use of external VAC dressing intra-operatively.

- Suspected bowel obstruction (partial or intermittent), strangulation, peritonitis, or
perforation.

- Active necrotizing fasciitis or any other known active local or systemic infection.

- Subject report of participation in an investigational drug or device study that would
impact the safety or scientific integrity of this study (in the opinion of the
Investigator and with the approval of the Sponsor) within the past 6 weeks prior to
treatment in this trial.
