My name is Natalia and I am from Russia. I recently joint to the clinical trial for keytruda and I had the 1st infusion just a week ago.
I will highly appreciate if those who had tried keytruda could share the first effect and feelings just after the 1st infusion. I faced with huge pain in tumors and increase of tumors. I heard that such could be. But how long such effect stay? ( days, weeks…?)
