Didn’t it go so that Faron would have continued with the 6mg/kg dose, but at the FDA’s insistence, they are forced to look for a smaller effective dose? This is to prevent potential side effects. So now they are testing the efficacy of 1mg/kg vs 3mg/kg in phase 2/3. Those wiser than me, please correct if I remember incorrectly.
Whether a smaller dose size provides sufficient efficacy remains to be seen. Let’s hope for the best.
