Would you stop bimekizumab in a patient who has severe psoriasis and has responded well to this therapy but is found to have newly diagnosed cirrhosis?

I believe there's no contraindication to bimekizumab in patients with cirrhosis. I would hope that the patient's hepatologist would find some other reason/cause for the cirrhosis. If the bimekizumab were to have caused cirrhosis (I'd be surprised if it ever did), I'd try to find another treatment.
