An Optional Two Year Follow Up Study to Study CP005A
Cat allergy is an increasingly prevalent condition affecting 10-15% of patients with allergic rhinoconjunctivitis and/or asthma.
The purpose of this optional observational follow-on study is to further evaluate rhinoconjunctivitis symptoms on exposure to cat dander in the EEC among subjects who completed all dosing visits in study CP005 and all visits in study CP005A approximately two years after the start of treatment.

Subjects previously randomized to receive placebo in study CP005 and completed CP005A.
Cat-PAD Group 1
Subjects previously randomized to receive Cat-PAD dose 1 in study CP005 and completed CP005A.
Cat-Pad Group 2
Subjects previously randomized to receive Cat-PAD dose 2 in study CP005 and completed CP005A.
Subjects who completed all visits in studies CP005 and CP005A will be invited to attend the Screening Visit for CP005B. Subjects will attend for 4 visits to the EEC on successive days. Following the last EEC visit is a follow-up visit which will be performed 3-10 days later.
