About

Evaluation of the efficacy and safety of SLIT with LAIS® Mites Sublingual tablets compared to standard drug treatment in patients aged over 60 years suffering from house dust mite (HDM) induced allergic rhino-conjunctivitis with/without asthma.

Full description

The Total combined score (TCS), taking into account the rhinoconjunctivitis total symptom score (RTSS) and the total rescue medication score (RTMS), in the maximum expected mites exposition period (V4-V5) For the RTSS and the RTMS, the daily values as determined by the patients in their diary card are collected during the observation period over 30 days. Then, the mean daily scores during that period are calculated for both parameters.

Enrollment: 45 estimated patients

Sex: All

Ages: 60+ years old

Volunteers: No Healthy Volunteers
