The primary efficacy parameter for each trial was the difference in the mean reduction in Total Nasal Symptom Score (TNSS) observed between the placebo and PreHistin over the fourth, fifth and sixth weeks of the studies. TNSS is a 12-point scale derived by summing and averaging all a.m. and p.m. scores for four symptoms: sneezing, runny nose, nasal congestion and nasal itch. Each symptom is given a score - 0 (none), 1 (mild), 2 (moderate) or 3 (severe) - resulting in a maximum recorded daily mean TNSS of 12. Patients maintained electronic diaries twice daily, self-rating their average symptoms over the previous 12 hours.

The Company delayed reporting preliminary top-line analyses from the two Phase III trials due to diary data entry inconsistencies. To evaluate wh
