Bowman Birk Inhibitor Concentrate and Oral Leukoplakia: A Randomized Phase IIb Trial[NCT00330382] | Phase 2 | 325 participants (Actual) | Interventional | 1999-01-31 | Completed | ||

"A secondary clinical response measure was bsaed on blinded, comparative judgments of pairs of photographs of the same lesion at baseline and 6 months on study. Picture pairs were assigned to album page, one pair per page, at random. Five physicians experienced with evaluation of oral mucosal tissue abnormalities, but blinded to study arm and time point, independently compared the pictures in each pair using a 7-point scale. The scale ranged from, top photo shows a complete response relative to the bottom photo, through, the same degree of disease is shown by top photo and bottom photo, to bottom photo shows a complete response relative to the top photo. Raw scores were transformed to account for relative position of the earlier and later photo, and averaged across the 5 reviewers. Final scores ranged from one, denoting a CR at 6 months, to 4, which indicated no change, through 7, which indicated that the 6-month photo depicted a much worse situation than the pretreatment photo."

The reviewer was blinded to study-arm assignment (drug or placebo), but not to time point of specimen. For each specimen, the reviewer marked a continuum to indicate degree of tissue abnormality. The continuum was 140 mm long, and anchored by the word 'Normal' on the left and 'Malignant' on the right. The distance from the left edge of the continuum to the reviewer's mark, in mm, was determined. For analyses, a score was formed by subtracting the pretreatment value from the 6-month value. Thus, a retreat from 'Malignancy' over time produces a negative score, a score of zero denotes no change, and a positive score denotes a worsening situation. Positive values indicate histologic worsening, whereas negative scores denote improvement over the 6-month study period. (NCT00330382)

Category of clinical response was based on the magnitude of relative percent change in total lesion area. A complete response (CR) was declared if the relative percent change in total lesion area was minus 100 percent. A partial response (PR) was a relative percent decrease in total lesion area of 50% or more, without being a CR. Disease progression was a relative percent increase in total lesion area of at least 50%. Remaining cases were declared to be stable disease. (NCT00330382)
