There seems to be different schools of thought on RTX dosage. No research results to help clarify the issue. Is it better to have smaller dosages more often or large dosages at longer periods of time?

Some doctors believe that the longer RTX is used, it tends to become less effective but there is no research yet to help answer this question? Or any research yet to address what the long term effects of RTX may be but it seems clear it is today the best treatment available for GPA if one is able to survive til the benefits kick in.
