Double Blind Randomized Phase IV Clinical Trial on bFGFRP in Vitiligo

All the above described clinical trials on bFGFRP were open ended. In view of the fact that western countries require only double blind clinical trials on any prospective drug for it to be approved as a drug, a multi-center double blind clinical trial was done on bFGFRP in combination with NBUVB or without. Two macules in non-sun exposed areas were selected on each patient with stable non-segmental vitiligo. The duration of treatment of volunteers was for 3 months starting with or without the topical application of bFGFRP followed by NBUVB on 30 patients. The results demonstrated that bFGFRP acted synergistically with NBUVB in repigmentation of the macules. More repigmentation occurred with NBUVB + bFGFRP at all-time points of evaluation (1, 2, and 3 months) than with NBUVB alone. NBUVB+ bFGFRP was superior to NBUVB alone in repigmenting vitiligo macules (23). Thus, it is clearly demonstrated that bFGFRP can be successfully used by itself or with synergistic effect in combination with many other modalities of treatment to treat vitiligo.

Major Conclusions

Growth factor deprivation theory as a possible cause of vitiligo (3) is in the light of the present literature mentioned above intimately intertwined with other prevailing theories of oxidative stress and auto immune theories (5). These theories are not mutually exclusive but interrelated and all together contribute to the loss of melanocytes resulting in vitiligo.
