BCM857

Main purpose To observe the in vivo kinetics of the active ingredient of BCM857 orodispersible film after a single oral administration in healthy Chinese subjects, estimate the corresponding pharmacokinetic parameters, and evaluate the bioequivalence using the original drug marketed in China as the control drug. Secondary purpose 1. To observe the safety of the BCM857 orodispersible film test preparation and the marketed control drug in healthy humans. 2. To compare the effects of different administration methods (water and no water) on the relative bioavailability of the test preparation under fasting conditions; 3. To evaluate the taste (palatability) of the BCM857 orodispersible film (test preparation, no water) and the marketed control drug taken by the subjects; 4. To investigate and record the dissolution time, mucosal adhesion and irritation of BCM857 orodispersible film (test preparation, no water) in the oral cavity.
