Evaluating the Efficacy of a Tocotrienols-Loaded Dressing in Wound Care for Pressure Ulcers (TOCOWO)

The purpose of this study is to investigate the effects of the dressing containing Tocotrienols on patients with pressure ulcers. This research is necessary because pressure ulcers is common in patient with critical illness and bedbound. Therefore, proper wound care management is crucial. Tocotrienols has been proven to have numerous health benefits, and in this study, its use will be investigated for pressure ulcers in human subjects. A total of 114 participants from patients admitted to UMMC (University Malaya Medical Centre) will be participating in this study. The whole study will last about 3 years and each participant will last about 43 days or 6 weeks.

This study is important because it is hypothesised that the Tocotrienols-loaded wound dressing will be able to reduce wound complications on application through its anti-inflammatory, anti-oxidant and wound healing effects, and provide better wound care outcome. This study also provides fundamental groundwork to expand the use of Tocotrienols in surgical and non-surgical wound management, as well as scar reduction in aesthetic and cosmetic applications.

The participants that are invited to participate in the research study because they have pressure ulcers that requires Tocotrienols-loaded formulated dressing. Participants should not take part in this study if they have multiple known allergies to various types of dressings, if their wound is determined to be infected, or if there are of skin necrosis requires special dressing and topical antibiotic treatment. Additionally, individuals with any medical conditions that, in the investigator's opinion, could potentially compromise their safety, adherence, or ability to successfully complete the clinical trial will also be excluded from participation.

This is a double-blinded randomized controlled trial. The procedure that is being tested is a Tocotrienols-loaded formulated dressing on Stage 1 and Stage 2 pressure ulcers. The participants will be randomly assigned to one of the treatment groups below:

Group 1: Tocotrienols-loaded formulated dressing Group 2: Conventional hydrocolloid dressing (standard of care as control) Neither the participants nor the doctor will know which group the participants are assigned to but in the case of emergencies, this information will be available to the doctor.

During the length of the study, the participants involvement will include:

• Being screened by the study doctor, who will examine their pressure ulcers and recruit them if they are eligible.
• If eligible, they will be randomly assigned to either the control or treatment group.
• Undergo 24-hour allergy testing with patch of Tocotrienol-loaded dressing and standard hydrocolloid dressing
• Assess skin sensitivity testing the next day, and if qualify, will be started on first dosing.
• Attend follow-up visits on days 3, 5, 7, 15, 22, 29, 35 and 43, where additional questions and assessments will be completed.
