|Estimated Study Completion Date :||June 2016|
|Experimental: E-101 Solution 300 GU/mL||
Drug: E-101 Solution 300 GU/ml
8 mL of E-101 Solution at a pMPO concentration of 300 GU/ml applied topically twice to surgical wound site (just after incision without penetration of the rectus fascia or linea alba and just prior to skin closure after closure of rectus fascia or linea alba).
|Placebo Comparator: Saline solution||
Drug: Saline solution
8 mL of Placebo topically twice to surgical wound site (just after incision without penetration of the peritoneal fascia and just prior to skin closure).
- The incidence of superficial (skin and subcutaneous tissues) and deep (muscle and/or fascia) incisional surgical site infections (SSI) involving the primary open-laparotomy incision. [ Time Frame: 30 days post-surgery ]Incisional SSI (both superficial and deep) will be diagnosed by a blinded assessor using a modification of the original SSI definition proposed by the the US Centers for Disease Control (Horan, Andrus and Dudeck. 2008. Am. J. Infect. Cont.)
- Mean CIWS (Clinical Infection Wound Score) [ Time Frame: 30 days post-surgery ]
Wounds will be assigned a whole integer value on a scale from 0 to 5 based on the severity of signs and symptoms associated with infection (e.g., wound erythema, spontaneous wound dehiscence) by a blinded assessor where a score of 0 is normal post-operative wound appearance and a score of 5 indicates infection of the primary incision involving deep incisional structures manifested by one or more of the following:
- spontaneous partial or complete wound dehiscence with erythema and/or pain
- spontaneous purulent drainage
- a wound abscess
- clinical or histological evidence of fasciitis or myonecrosis
- Proportion of subjects with incidence of incisional SSI, accompanied by findings of purulent drainage, wound abscess, or positive microbial culture from one or more incisional samples [ Time Frame: 30 days post-surgery ]
- Proportion of subjects with incidence of superficial and deep incisional SSI [ Time Frame: 14 days post-surgery ]
- Quality of life scores based on the EQ-5D-3L questionnaire obtained via interview of the subject by qualified study site personnel [ Time Frame: At Screening, 7, 14, and 30 days post-surgery ]This evaluation will only be performed for English-speaking subjects at US sites.
- Proportion of subjects re-hospitalized for SSI. [ Time Frame: 30 days post-surgery ]
- Proportion of subjects with each wound healing score by a blinded assessor on a standardized quantitative scale (termed Clinical Wound Healing Score [CWHS]) [ Time Frame: 3, 5, 7, 14, and 30 days post-surgery ]
The points on the CWHS scale are the following:
- 0 = normal, intact incision without any spontaneous wound dehiscence
- 1 = spontaneous wound dehiscence that extends < 2 cm along primary incision in the absence of erythema and/or pain
- 2 = spontaneous wound dehiscence that extends ≥ 2 cm along primary incision in the absence of erythema and/or pain
- Wound pain score assessments [ Time Frame: 3, 5, 7, 14, and 30 days post-surgery ]Wound pain assessment will be based on a categorical scale ranging from 0 to 10, where 0 is no pain and 10 is unimaginable, unspeakable pain. The worst assessment over all days will be summarized by treatment group whereby the number and percent of subjects whose worst pain assessment is 0, 1, 2, 3...10 will be presented.
- Incidence of detectable, induced antibodies to components of E-101 Solution [ Time Frame: Up to 6 months post-surgery ]Serum samples collected 14 days and 30 days after surgery will be screened for antibodies to components of E-101 solution as compared to results from pre-treatment samples. For any subject in which there is detectable, induced antibodies by ELISA, the serum samples will be screened for neutralization. Subjects who have detectable induced antibodies 30 days after surgery will be asked to provide an additional sample 3 months after surgery, and again at 6 months after surgery if induced antibodies are still detectable at the 3 month visit
- Independent Adjudication Committee Review [ Time Frame: 30 days post-surgery ]As a sensitivity analysis, an independent, blinded adjudication committee will be convened to review all cases of SSI with CIWS scores of 1, 2, or 3 that lack positive microbiological findings). The independent adjudication committee will score cases as likely or unlikely SSI, based on review of photographs of the primary incision and on key study data collected prior to the SSI diagnosis.
- Incidence of perinuclear anti-neutrophilic cytoplasmic antibody (p-ANCA)-associated vasculitis [ Time Frame: 30 days, 6 months ]A subset of 300 subjects (150 subjects from each study arm) at selected study sites will be evaluated for p-ANCA-associated vasculitis. Incidence of p-ANCA-associated vasculitis will be determined by ELISA screening for induced antibodies to human myeloperoxidase, serum anti-nuclear antigen test detected by immunofluorescent microscopy (IFM), serum complement 3 [C3], serum complement 4 [C4], complete blood count, urinalysis (microscopic and chemistry), coagulation tests, serum chemistries, and physical examinations for vasculitis symptoms.
