I find it strange rather than interesting.
The problem is if a doctor comments on something that they don't know much about then I begin to question everything they say.
Remember Fluge and Mella didn't report any serious side effects if their trials, so where is all this safety concern coming from.
i think that the lack of knowledge and worry that chemotherapy means 'hard drug' or toxic drug is at play here. Targeted therapy that is Rituximab is a beautiful thing because it doesn't affect non-targeted cells, unlike other chemotherapies for cancer which affects fast reproducting cells and give patients all kinds of symptoms and toxicities.
Then drs get worried about the drug reaction during infusion which is experienced by 75% of those getting it for the first time(my estimation from my experience as a RN) and that resolve by giving Benadryl and hydrocortisone. And in 99% of the cases the infusion can be resumed and completed.
What is important is that the infusion needs to be given in or near a hospital setting and by experienced staff who knows what to do in case of a reaction.
Lastly, it is my opinion that a life-changing disease which strips patients of their dignity, of their work and themselves deserve appropriate treatments, diagnostics research that commensurate burden of disease and access to clinical trial using drugs that have the necessary power to knock the disease down. I feel strongly about that. It may not be everyone's cup of tea but it is mine.
