In contrast to the three-day observation period, mean TNSS of the last five days of the allergen challenge series showed statistically significant reductions in mean TNSS differences between AZD3778 and placebo for morning as well as evening observations (p = 0.023 and 0.022, respectively) (Tables 4 and 5). In contrast, no such effects were observed for loratadine.Lavage fluid observationschallenges, AZD3778 reduced the levels of ECP compared with placebo (Figure 3). For the lavage obtained pre-bradykinin challenge, the numerical reduction in ECP failed to reach statistical significance (Figure 3), whereas the reduction was statistically significant for the post-bradykinin observation (p = 0.038) (Figure 3). Also, focusing on post-bradykinin observations, AZD3778 reduced the levels of ECP compared with loratadine (p = 0.012) (Figure 3). Neither AZD3778 nor loratadine reduced the levels of tryptase and a 2 -macroglobulin (Figure 3).In the placebo run, nasal lavage fluid levels of tryptase, ECP, and a 2 -macroglobulin were elevated in saline lavage fluids collected late into the allergen challenge series (c.f. baseline observation prior to the challenge series) (Figure 1). Also, compared with the baseline as well as with the saline lavage carried out late into the allergen challenge series, bradykinin produced increased levels of a2-macroglobulin (Figure 2).
