Healing in adults is relatively inefficient often associated with undesirable scar formation. In the study, published recently in Molecular Therapythe team focused on a protein called nonselenocysteine-containing phospholipid hydroperoxide glutathione peroxidase, or NPGPx. NPGPx is active in fetal tissue but becomes mostly inactive in the skin after birth. Researchers used tissue nanotransfection technology developed by faculty at the ICRME to deliver the NPGPx gene to the wound site.

Wound healing studies -

Since it was not our intent to focus on the analysis of data from any particular clinical trial, the minimal description of experimental data was sequentially measured diabetic neuropathic foot ulcers in patients treated with various therapeutic wound healing agents, their respective vehicle controls, or standardized care.

At all measurement times, the wound perimeters were traced on clear plastic sheets and the wound areas calculated planimetrically. The ulcers were measured weekly for a defined period determined by the parameters of the particular clinical trial, most commonly 20 weeks days.

In addition, the percentage of patients who achieved total healing was plotted vs time of wound treatment days for both centers to determine how patients with diabetic neuropathic foot ulcers receiving at least debridement, off-loading, and frequent monitoring heal their ulcers. Survival analyses were done using the Kaplan-Meier method, with both log-rank and Wilcoxon statistics to test for differences between groups.

Percentage healing refers to the diminishment of wound area relative to day zero as follows:. Calculations and graphs were done using JMP software SAS Institute Inc, Cary, NC and Sigma Plot software SPSS Inc, Chicago, Ill.

The wound healing trajectories were almost identical for patients achieving complete healing at the 2 centers Figure 1. This was true whether one evaluated the mean or the median percentage healing vs time of treatment.

Survival analysis of patients entering these clinical trials at the 2 centers who achieved total healing each week is shown in Figure 2. Almost no total healing occurred until 28 days 4 weeks.

Based on the linear relationship demonstrated in Figure 2 , this would occur at 37 weeks. Improvement in wound healing is a goal that has rapidly gained the interest of clinicians, researchers, and industry.

Animal studies have suggested that the various processes of the healing scheme including coagulation, inflammation, matrix synthesis and deposition, angiogenesis, epithelialization, contraction, and remodeling can be accelerated. Measuring this outcome for a particular new therapeutic agent in human clinical trials has been difficult.

The practical difficulty and expense of conducting a closely monitored wound healing trial of 9 months' duration is immense. The result would be that the patients who were healing on a slower trajectory may drop out before completion of the study.

Faster-healing patients would have to remain in a closely monitored follow-up period and could theoretically lower the morale of the slower-healing patients being followed in the trial.

These are some of the reasons for attempting to identify intermediate end points that can serve as valid efficacy end points. As Hokanson et al 8 have described, the distributions of these fractional closure times and statistical differences in these distributions can then be determined using statistical methods similar to those used for failure-time or survival analyses.

Many of the problems of comparing healing in multiple groups are averted with this method. The wounds are normalized by using a fractional decrease in wound size or percentage closure to be consistent with the analysis of chronic wounds that vary greatly in size.

Healing trajectories provide more information about the entire continuum of the wound healing processes. Statistical comparisons at these extremes may be noninformative and stress the need for statistical techniques that allow dynamic comparisons at biologically meaningful interim values.

Wright et al 28 have suggested that "normal" and "impaired" healing exist on a continuum and are a compromise from "ideal" healing. In attempting to accelerate acute incisional wound healing depicted by a breaking strength or tensile strength vs time curve, they discuss the concept of moving the wound healing process in the direction of the "ideal.

Conceptually, the wound healing trajectories used to depict the data of the chronic diabetic neuropathic foot ulcer wounds are similar to the gain in wound strength curves used to depict data from healing acute surgical incisions. If the predictive value of such wound healing trajectories can be determined for the various other types of human chronic wounds, such as pressure ulcers and venous stasis ulcers, possibly shorter clinical trials can be constructed relying on specific shifts of the wound healing trajectories from impaired healing toward an ideal end point.
