ProMetic will assist WIBP to implement a product development program that is being initiated immediately, which includes training, technology transfer, and scale up, as well as readiness of the clinical manufacturing facility. WIBP will take the lead in conducting the clinical trials to obtain required regulatory approval by the Chinese State Food and Drug Administration ("SFDA"). Full scale commercial manufacturing will take place at WIBP initially, could be readily implemented by other affiliated companies within CNBG later, with the goal to achieve a minimum capacity greater than 1.2 million L plasma per year.
