Ertherdermic Psoriasis and treatments

Interested to get treatment results from others who have this type of Psoriasis.I was diagnosed in July last year and was admitted to hospital eventually..Once I was on cyclosporin the condition improved dramatically but as you cant stay on it I have been moved onto Amgevita which 4 weeks in is not showing anywhere near as good results so far. I wondered if anyone had combined amgevita with uvb light therapy with any success,any comments experience much appreciated:-)
