(6)Market:

16.7 million population are affected by severe asthma which is refractory and causes huge medical burden. There are currently only a few biologics approved for treatment of eosinophilic severe asthma whereas there remains no effective drugs to control neutrophilic and mixed granulocytic severe asthma.IL-6 is the potential key cytokine to the pathogenesis of these two subtypes in severe asthma.
4.Any other matters that need to be specified:
(1)The protocol of the phase 2 clinical trial was already greenlighted by US FDA so the same protocol to TFDA was submitted via fast track which has been approved.
(2)FB704A (anti-IL6 mAb) may improve symptoms of neutrophilic and mixed granulocytic severe asthma by inhibition of classic and trans-signaling pathways of IL-6. Among the patients with these two subtypes of severe asthma, it is likely that FB704A may reduce Th1, Th2 and Th17 inflammation as well as airway hyper-responsiveness. The application submitted to TFDA is for treatment in patients with severe asthma who have higher neutrophil counts in sputum. Such subtype of severe asthma can't be well controlled by current treatments and FB704A will explore the possibility of improving symptoms on those severe asthma patients with higher neutrophil counts.
(3)According to Article 2 under Guidelines by Taipei Exchange on the Material Information Announced by Listed and OTC Companies, new drug development companies shall make public announcement when filing application for clinical trials or new drug application to domestic or overseas regulatory authorities, receiving approval or disapproval, obtaining the statistical date of endpoints in each clinical trial (including interim analysis), or receiving approval or disapproval on drug license application.
(4)It takes considerable time and expenses to develop a new drug of which success can't be guaranteed. Investors shall bear such investment risk that warrants careful assessment before making investment decisions.
