would be tough to blind an injectable drug with an oral drug
As an aside, Actimmune is a 3x week injectable and it is being blinded. Its a terrible enough disease and then to receive a Placebo injection! One way this could be interpreted is the lack of options speak to what patients/docs will try (though it is available off-label). Also, this is one reason why I speculate that Pirfenidone should complete enrollment much earlier then company forecast (prior posts). One could speculate the hurdle for approval is lower as well.

sorry misread the part about blind injectable with Oral, thought injectable period. You can delete this post
