Clinical Trial Summary

To follow up the efficacy and safety of Candida antigen, bivalent HPV vaccine in treatment of common warts either mono or combined intralesional therapy

Description:

• Group A: 25 patients will be treated with Candida antigen. All patients will be directly injected with Candida antigen into the largest wart using an insulin syringe. Injections will be done at 2-week intervals until complete clearance will be achieved or for a maximum of five treatment sessions.

• Group B: 25 patients will be treated with bivalent HPV vaccine solution intralesional into the largest wart using an insulin syringe. Injections will be done at 2-week intervals until complete clearance will be achieved or for a maximum of five treatment sessions.

• Group C: 25 patients will be treated with both agents intralesionally into the largest wart using an insulin syringe at 2-week intervals until complete clearance will be achieved or for a maximum of five treatment sessions.

it is thought that candida antigen act through a cell-mediated immune response and bivalent HPV vaccine act mainly through humoral immunity, so we want to study their effect as single or mixed agents

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	complete response	if there is disappearance of warts and return of the normal skin markings	upto 3 months
Primary	partial response	if warts regressed in size by 50-99% (the size will be measured as the summation of size of all lesions in cm)	upto 3 months
Primary	no response	if there is < 50% decrease in wart size. (the size will be measured as the summation of size of all lesions in cm)	upto 3 months
Secondary	recurrence rate after recovery	appearance of new lesions or recurrence of previous one	follow up for 6 months after recovery
