AB Science : Phase 3 asthma fully enrolled

Paris, 6 March 2017, 8am
The phase 3 study in severe persistent asthma uncontrolled by oral corticosteroids has completed patient recruitment. Final results will be available at the end of 2017.
A new phase 3 study has been initiated in asthma uncontrolled by high-dose inhaled corticosteroids and with elevated eosinophil level.

AB Science SA (NYSE Euronext - FR0010557264 - AB), a pharmaceutical company specialized in the research, development and marketing of protein kinase inhibitors (PKIs), announced today that the phase 3 study (AB07015) in severe persistent asthma uncontrolled by oral corticosteroids has completed its predefined recruitment of 350 assessable patients. Final results will be available at the end of 2017.

Given the success in recruiting the targeted number of patients, AB Science has decided to continue the study until completion, even in the event of the interim analysis being successful, in order to provide evidence of efficacy in a sufficiently large number of patients for registration. This decision has been communicated to the Independent Data Monitoring Committee (IDMC) prior to the study`s interim analysis, which was planned with 50% of the patients.

Consequently, the IDMC has not communicated to AB Science the interim analysis results but has indicated that the study can continue on the basis of the safety data and did not request implementation of the protocol resampling option.

As a reminder, the protocol provided for a resampling option (possibility of doubling the number of patients to be included) to be implemented should any positive trend observed at the interim analysis be insufficient for the study to be successful with the initial number of planned patients, thereby necessitating recruitment of additional patients to obtain a statistically significant demonstration.

Asthma uncontrolled by oral corticosteroid represents the most severe form of asthma (GINA* step V patients that are uncontrolled) and represents a high unmet medical need. The quality of life of these patients is severely impacted, with major reduction in lung function, restrictions on activities of daily living, work absenteeism, night-time awakening several times a week, frequent exacerbations and greater risk of life-threatening asthma exacerbations. The target population in adult patients is estimated at 70,000 in the USA and in the EU.

In order to expand the asthma franchise, AB Science has initiated a new phase 3 study (AB14001) in asthma uncontrolled by high-dose inhaled corticosteroid plus long-acting beta-agonists (LABAs) and with elevated eosinophil level. This study has recruited its first patients. This new indication is much broader and is estimated to affect 1,500,000 adults in the USA and Europe.
