ST266 Versus Standard Care In Treating Partial Thickness Burns
Phase I/II Randomized Blinded Safety, Dose-determining Efficacy Trial Comparing Amnion-derived Cellular Cytokine Solution in 3 Different Regimens With Standard Care 0.9% Sodium Chloride in the Topical Treatment of Partial-thickness Burns
Přehled studie
Detailní popis
A Phase I/II multi-center clinical trial will be performed in 99 adults with partial-thickness burns. Two similar partial-thickness burn areas in a single patient will be selected. One burn will be randomly assigned to receive either test drug ST266 or normal saline in one of three treatment regimens.
The three treatment arms will be:
- ST266 0.01 mL/cm2 every 7th day vs. normal saline 0.01 mL/cm2 every 7th day;
- ST266 0.01 mL/cm2 every 4th day vs. normal saline 0.01 mL/cm2 every 4th day; and
- ST266 0.01 mL/cm2 every other day vs. normal saline 0.01 mL/cm2 every other day.
Two different preclinical studies of partial-thickness burns on guinea pigs have demonstrated accelerated epithelialization with topical treatment with ST266. Similarly, preclinical studies in Yorkshire pigs have demonstrated more rapid maturity of epithelialization and better quality healing of partial-thickness skin graft donor sites with ST266 treatment.
In the preclinical studies, ST266 given in a dose of 0.01 mL/cm2 wound area appeared to saturate the wound adequately without excess and simultaneously improve healing. In preclinical toxicity studies, the dose of 0.01 mL/cm2 was shown to be safe.

Popis
Inclusion Criteria:
- A signed IRB (Institutional Review Board)- approved Informed Consent Form;
- 18 - 65 years of age;
- Two (2) similar, non-contiguous, partial-thickness burn wounds between 50 cm2 and 250 cm2 in area with blisters removed in a Total Body Surface Area(TBSA) burn of less than or equal to 40% TBSA;
- Burns must be thermal burns of flame or scald etiology;
- Patient must present to the burn center within 8 hours of injury;
- Normal creatinine and bilirubin levels;
- If capable of bearing children, patient must be using a medically accepted means of birth control and have a negative serum pregnancy test;
- Willing to participate in the clinical study and comply with the requirements of the trial.
Exclusion Criteria:
- The two (2) chosen wounds must not be full-thickness (extending through the dermis into the subcutaneous tissue);
- Thermal burn from chemical, electrical or radiation causes;
- Neither the study wound nor the comparator wound can be < 50 cm2 or >250 cm2 in size and cannot be on the face or hands;
- Patients with significant pulmonary injury, i.e., smoke inhalation injury requiring ventilator support;
- Patients with diabetes;
- Patients with any immune deficiency including current treatment with corticosteroid medication, chemotherapeutic agents, anti-viral therapy, or concurrent radiation therapy within 30 days of signing the informed consent;
- Abnormal bilirubin, liver function studies (i.e., Alanine transaminase (ALT); Aspartate transaminase (AST)> 2.0 times normal);
- Abnormal serum creatinine, receiving hemodialysis or peritoneal dialysis;
- Active cancer or a history of cancer in the 5 years prior to signing the informed consent form (history of basal cell carcinoma is allowed);
- Psychiatric condition or substance abuse which in the Investigator's opinion may pose a threat to patient compliance;
- History of non-compliance with treatment or clinical visit attendance.
- Patients whose burns were previously treated with anything other than ice, cold water or dry dressing.
- Participation in an investigational trial within 30 days of study entry.

ST266 is a clear liquid containing more than 200 proteins, cytokines, and growth factors in solution.
Patients will be treated for 21 days unless both wounds have healed prior to 21 days, at which time a punch biopsy of the epithelialized area of each wound will be performed.
A study evaluation visit for assessment of the biopsy site will occur on day 28 or within 7 days of the punch biopsies, whichever occurs first.
Six months after the punch biopsy, the patient will return to the burn center for a final examination and photographs of the study wounds.
