D-PLEX 311: Safety and Efficacy of D-PLEX in the Prevention of Post Abdominal Surgery Incisional Infection

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.

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. The final number of subjects will be determined following a comparative interim analysis for an early efficacy or futility stop or unblinded sample size re-estimation: when about 750 subjects will complete their 30 days (1 month) follow-up and evaluated for primary endpoint
