OK to put this in context I am replying from Australia.
I work on an oncology unit that also at times has to administer antineoplastic therapies on other wards and our practice is to treat all therapies the same.
Also to add to this the Cancer Nurses Society of Australia put out a statement several years ago in relation to the administration of immunotherapies that basically said that due to the newness of these therapies and therefore the lack of long term data on incidental exposure to these agents that they should be treated the same as cytotoxic chemotherapies.
In other words best to be safe than sorry and treat it like chemotherapy.
We also wouldn't let anyone administer this that hasn't done appropriate courses to be qualified to administer this type of therapy.
Hope this helps
