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.
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.
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 manner 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 pharmacokinetics (PK, for some only) as well as physicians assessment of the incisional wound.
