Brief Summary

Phase III, Prospective, Multinational, Multicenter, Randomized, Controlled, Two-arm, Double Blind Study to Assess Efficacy and Safety of D-PLEX Administered Concomitantly with the Standard of Care (SoC), Compared to a SoC Treated Control Arm, in Prevention of Post Abdominal Surgery Incisional Infection.

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.

The study population includes male and female, 18 years old and above at screening, undergoing an elective colorectal surgery involving colon or rectal resection, with or without a stoma formation, that includes at least 1 incision that is \> 20cm (target incision).

Eligible and willing subjects will be randomly allocated into 2 blinded study arms, either to the investigational arm (D-PLEX + SoC) or to the control arm (SoC only) in a 1:1 ratio. Subjects will be stratified by type of prophylactic SoC (IV antibiotic only, IV antibiotic with mechanical bowel preparation or IV antibiotic with oral antibiotics combined with mechanical bowel preparation) and by region (US versus Europe + Israel).

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 and chemistry as well as physician's assessment of the incisional wound.

  4. Subjects undergoing concomitant major procedures in addition to the colorectal resection.

    Female sterilization surgeries (i.e. salpingo-oophorectomy etc.), involvement of a small bowel procedure or cholecystectomy may be allowed, pending an advanced consultation and approval from the Sponsor .

  7. Subjects who received oral or IV Doxycycline or Tetracycline family antibiotics during the past 4 weeks prior to randomization.

  8. Subjects with known allergy to Doxycycline and/or to the tetracycline family of drugs or to the D-PLEX's excipients.

  9. Subjects with known allergies to more than 3 substances (an allergy questionnaire will be completed during the screening process).

  11. Subjects with End Stage Renal Disease (ESRD/ CKD stage 5).

  12. Subjects with severe hepatic impairment.

  13. Subjects with chronic urticaria.

  14. Subjects diagnosed with CVA within the past 6 months prior to randomization.

  16. Any subject with an active malignancy or with malignancy that has not been in complete clinical remission and without maintenance chemo or immunotherapy for at least 3 years.

    Excluding: Subjects with potentially resectable non-metastatic colorectal cancer, that is the reason for the index surgery.

    Subjects who have had carcinoma in situ (or other cancer "in situ = Stage 0"), or squamous cell carcinoma of the skin, or basal cell carcinoma of the skin.

    Subjects with any additional non-violent cancer that does not require treatment 4 weeks prior to the surgery, and throughout the entire study duration.

  17. Subjects with other concurrent severe and/or uncontrolled medical condition.

  18. Psychiatric or any other disorder that compromises ability to provide informed consent for participation in this study.

  19. Chronic alcoholic or drug abuse subjects.

  22. Subjects participating in any other interventional study.

  23. Subjects who in the opinion of Investigator, are not eligible to participate in the study and/or to comply with the protocol requirements (e.g. due to a cognitive or medical condition).

Primary Outcome Measures
NameTimeMethod
To assess the anti-infective efficacy of D-PLEX over a period of 30 days post operation, by preventing surgical site infection (SSI), defined as superficial and deep infection, in the target incision(s), compared to the SoC treated control.By day 30 post surgery

Infection rate as measured by the proportion of subjects with at least one abdominal incisional infection event, as determined by a blinded and independent adjudication committee, within 30 days post abdominal surgery. \[abdominal incisional infection is composed of Deep Incisional Surgical Site Infection (DSSI) and Superficial Incisional Surgical Site Infection (SSSI)\].within 30 days post abdominal surgery and determined by a blinded and independent adjudication committee.

All-cause mortality and re-interventions in the target incision within 30 days post index surgery will be analysed as treatment failure.

Incisional infection event only, occurred within 30 days post abdominal surgery and determined by a blinded and independent adjudication committee.

\[abdominal incisional infection is defined as Deep Incisional Surgical Site Infection (DSSI) and/or Superficial Incisional Surgical Site Infection (SSSI)\].

Safety of D-PLEX in Prevention of Post Abdominal SurgeryBy day 60 post surgery

Safety parameters will be evaluated by adverse events

Safety of D-PLEX in Prevention of Post Abdominal Surgery IncisionalBy day 60 post surgery

Incisional wound healing will be assessed by a blinded Investigator, using a visual examination as well as Modified Vancouver Scar Scale wound assessment questionnaires. The questionnaire has a numeric scale from 0-4 in Vascularity, Pigmentation, Pliability and height
