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 resection, with or without a stoma, that includes at least 1 incision that is > 10 cm (target incision). Eligible and willing subjects will be randomly allocated into 2 blinded 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 and chemistry well as physicians assessment of the incisional wound.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||600 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||Males and females, >18 years old, undergoing scheduled abdominal colon surgery involving resection and anastomosis or a stoma, who meet the inclusion criteria and none of the exclusion criteria and provide signed informed consent will be enrolled in the study.|
|Masking:||Triple (Participant, Care Provider, Investigator)|
This is a double-blind clinical trial. The sponsor, the subjects, outcomes assessor and all staff involved in the collection and recording of the clinical and laboratory data, based on which the independent adjudication committee will perform their assessment, will be blind to treatment assignment. In addition, all aspects of data management and clean-up will be done in blinded datasets.
The study site personnel, who perform the index surgery (Operation room staff), will be trained not to disclose the treatment arm to the blinded Investigator, to the subject, his/her family, to other health care providers not present during the surgery or to the study Sponsor representatives. Wound assessment throughout the study follow-up visits will be done by a blinded Investigator, that will not be involved in the surgery. An emergency card containing the Study Name, NIH number, Center Name/number, PI's name and contact details will be provided to the subjects. S

D-PLEX is provided to suitable and willing study subjects as an adjunct to the SoC treatment
D-PLEX is a new formulation of extended release of Doxycycline. Each 5g D-PLEX vial contains 54.6mg Doxycycline free base (1.09%), which is equivalent to 63mg Doxycycline hyclate (1.26%). D-PLEX is supplied as a sterile powder to be reconstituted to paste in the operating room, using standard aseptic techniques and is intended for single administration. The non-active components of the extended release antibiotic formulation are β Tri-Calcium polymer and a lipid matrix. All formulation components are biodegradable.
Standard of care
The SoC for prophylactic antibiotic treatment is based on international guidelines
Other: Standard of Care (SoC)
prophylactic, pre-operation per institution guidelines
- 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. [ Time Frame: 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)].
- Assess Safety of D-PLEX in Prevention of Post Abdominal Surgery Incisional [ Time Frame: By day 60 post surgery ]Safety parameters will be evaluated by adverse events
- Assess Safety of D-PLEX in Prevention of Post Abdominal Surgery Incisional [ Time Frame: By 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
- All-cause mortality and re-interventions in the target incision [ Time Frame: By day 30 post surgery ]All-cause mortality and re-interventions in the target incision within 30 days post index surgery will be analysed as treatment failure.
- Assessment of Infection rate in patient undergoing abdominal colon surgery [ Time Frame: At study visits: day 1, day 5, day 14 and 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)].
