Platelet Derived Growth Factor (PDGF) is a potent mitogen for a wide range of cell types including fibroblasts, smooth muscle and connective tissue. Recombinant human platelet derived growth factor (R-Pdf/Gbb) has biologic activity similar to endogenous platelet derived growth factor (PDGF). Biologic activity of PDGF includes encouraging chemotaxis and proliferation of cells responsible for wound repair and it augments production of granulation tissue.

The growth factor rhPDGF is found effective in patients having diabetic foot ulcer grade III and IV. The nature of wounds in the third degree burns is similar so far as healing process is concerned.

The purpose of this study is to test the hypotheses that the application of R-Pdf/Gbb 0.01% gel on the third degree thermal and electrical burns will heal these wounds within 3 months and there will be improvement in general condition of the patients without any complications.

Primary Outcome Measures:
  • Complete healing of the third degree burn wound. [ Time Frame: 3 months. ]

Secondary Outcome Measures:
  • Improvement in general condition of the study subjects without any complications. [ Time Frame: 3 months. ]

Estimated Enrollment: 120
Study Start Date: July 2011
Estimated Study Completion Date: April 2012
Estimated Primary Completion Date: April 2012 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: R-Pdf/Gbb 0.01% gel
    rhPDGF 0.01% gel is applied to the wound, then covered with dressing once daily for 3 months
    Other Name: Recombinant human platelet-derived growth factor
Detailed Description:

The R-Pdf/Gbb is recombinant human platelet-derived growth factor. It has been demonstrated that rhPDGF is effective in enhancing wound healing.

OBJECTIVE: The primary objective of the study is to determine the efficacy of R-Pdf/Gbb gel in treating wounds caused by III degree thermal and electrical burns.

HYPOTHESIS 1: That the applications of R-Pdf/Gbb 0.01% gel on III degree thermal and electrical burns will heal these wounds within 3 months.

HYPOTHESIS 2: Subjects, who having III degree thermal and electrical burns with the treatment of R-Pdf/Gbb 0.01% gel, will show improvement in general condition without any complications.

We aim to test these hypotheses by evaluating the clinical outcome in about 120 patients after three months of treatment with R-Pdf/Gbb 0.01% gel applied once daily.
