Phage Therapy for the Prevention and Treatment of Wound Infections in Burned Patients

December 21, 2021 updated by: Phagelux Inc.

A Randomized, Open-Label, Active Controlled Study to Evaluate the Safety and Tolerability of a Phage Cocktail-SPK Therapy in Second Degree Burn Wounds in Adult Patients

The central aim of this trial is to investigate the safety and tolerability of Phage Cocktail-SPK as an adjunct to standard therapy for the prevention and treatment of burns susceptible to infection/or infected by S. aureus, P. aeruginosa, or K. pneumoniae species. It is hypothesized that no adverse events, clinical abnormalities, or changes in laboratory tests results related to the application of Phage Cocktail SPK Spray will be observed.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a Phase I, randomized, open-label, active controlled study to evaluate the safety and tolerability of a Phage Cocktail-SPK therapy for second degree burn wounds in adult patients. The wound will be clinically selected on the basis that it is a second degree burn less than 10 percent of total body surface area, and that, according to medical assessment, should heal without surgical intervention. The study is intended to include one site outside of the United States of America, namely the Royal Brisbane and Women's Hospital, in Brisbane, Queensland, Australia.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
