• Primary endpoint met
  • Statistically significant dose-response relationship (p < 0.01)
  • All dosing regimens were safe and well tolerated
  • Adherence was greater than 90%

WORTHING, UK I May 9, 2016 I Allergy Therapeutics, (AIM: AGY), the fully integrated specialty pharmaceutical company specialising in allergy vaccines, today announces positive top-line results from the Company’s PQBirch204 Phase II study, a multi-centre, double-blind, placebo-controlled study designed to explore the safety and response of different cumulative doses of Birch Modified Allergen Tyrosine adsorbed and MPL® (POLLINEX® Quattro Birch) for birch pollen induced seasonal allergic rhinitis.

The study randomised 371 patients into six cumulative dosing regimens plus a placebo, evaluating the change in Total Symptom Score (TSS) following a conjunctival provocation test (CPT) with the objective to achieve a dose recommended for Phase III development.

Results summary of the PQBirch 204 Phase II study programme

  • The primary endpoint, to demonstrate a statistically significant (p < 0.01) dose-response for the 5000 standardised units (SU) to 27300 SU, was met. This enables prediction of the dose to enter Phase III development
  • The study demonstrated a statistically significant (p < 0.01) dose-response for the 5000 standardised units (SU) to 27300SU dose range studied
  • The dose-response closely followed and extended the findings of the previous dose-response study (PQBirch203), which studied doses from 600SU to 13600SU
  • PQBirch continues to be well-tolerated and no safety concerns were reported in any treatment arm. There was no significant relationship between any adverse drug reaction exhibited and the respective dosage of allergoid
  • Overall adherence to the dosing regimens was approximately 94% with no relevant differences between treatment arms.
