D-PLEX 310: Safety and Efficacy of D-PLEX in the Prevention of Post Abdominal Surgery Incisional Infection
Phase II, Multicentre, Randomized, Controlled, Two Arm, Single Blind Study to Assess Safety and Efficacy of D-PLEX Administered Concomitantly With SOC, Compared to SOC, in Prevention of Post Abdominal Surgery Incisional Infection.
Subjects who are planned to undergo an abdominal (colon) surgery and who will meet the study entry criteria will be randomly divided into 2 groups: for half D-PLEX will be administered concomitantly with the standard of care (SOC). The other half will receive the Standard of Care treatment.
Following the surgery subjects will be followed up for additional 5 visits, at least half are in line with the routine practice of surgery Follow-Ups.
Visits will include patient safety and wound assessments.

Detailed Description
D-PLEX is a new formulation of extended controlled release of Doxycycline in the applied area for about 30 days. This study is aimed to assess the safety and efficacy of D-PLEX in prevention of post abdominal surgery incisional infection.
Eligible and willing subjects will be randomly divided, in a single-blinded manor into 2 study arms D-PLEX with SOC or SOC alone. D-PLEX will be applied during the surgery at the final stage of incision closure. All patients will be followed up for additional 5 visits over 2 months, for safety and incisional wound assessment. This will include blood tests for hematology, chemistry and PK (for some only) as well as physicians assessment of the incisional wound.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Other: Standard of Care (SoC)
SOC prophylactic treatment pre-operation will be as per Israeli Ministry of Health and international guidelines: 1st or 2nd generation of Cephalosporine family, plus Metronidazole.
|
Prophylactic, pre-operation: 1st or 2nd generation of Cephalosporine family, plus Metronidazole. Post-operation: this is each participating center standard practice for this type of procedure |
Experimental: D-PLEX + SoC
D-PLEX is provided to suitable and willing study subjects as an adjunct to the SoC treatment
|
Prophylactic, pre-operation: 1st or 2nd generation of Cephalosporine family, plus Metronidazole. Post-operation: this is each participating center standard practice for this type of procedure
D_PLEX is reconstituted into paste and administered in a single application following closure of the fascia, on the fascia suture line, and on the soft tissues of the abdominal wall along the whole length of the surgical wound (including muscle, fat and dermis).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Infection rate as measured by the proportion of subjects with abdominal incisional infection event
Time Frame: By day 30 post surgery
|
Infection rate as measured by the proportion of subjects with abdominal incisional infection event, as determined by a blinded and independent adjudication committee, within 30 days post abdominal surgery.
|

|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Average ASEPSIS assessment score (Additional treatment, Serous discharge, Erythema, Purulent exudate, Separation of deep tissue, Isolation of bacteria, Stay duration as inpatient) during 30 days post-surgery.
Time Frame: At post surgery study visits : day 1, day 5, day 14 & day 30
|
ASEPSIS is acronym of wound assessment and treatment parameters (described in the title), which provides numerically score during an inspection of the surgical site. The final score is being interpreted to severity of wound appearance and the clinical consequences of the infection. Each parameter will be evaluated and numerically scored. Some (Serous discharge & Erythema) will be marked between 0 - 5 and others (Purulent exudate & Separation of deep tissue) are marked between 0 - 10 - based on the proportion of the wound they affect when 0 is none and either 5 or 10 are for over 80% of the wound. Other parameters (Additional antibiotic treatment, a requirement for pus drainage, solation of bacteria & Stay duration as an inpatient) are scored Yes or No. No equals 0. Yes is calculated as either 5 points (for some parameters) or 10 for others. The final score can in the range of 0 - 70. 0 - 10 for wound which heals satisfactorily and over 40 for a severe wound infection. |

Susceptibility to Doxycycline for any organisms recovered from an abdominal surgery incisional Infection site will be done using a central lab. When an infection is suspected in the incisional wound, a sample will be taken and sent for a bacteriology test in a central lab. Any organism which will grow (if), will be further tested for Doxycycline susceptibility. |

|
Out of the entire hospitalization period, how many days were attributed due to a surgical site infection
|
During 60 days of study participation
|
Number of antibiotic treatment days post surgery
