Apologies, ‘off label’ just means meds taken not for their intended purpose. I use a private clinic, ‘Care Oncology Clinic’ (COC) and take atorvastatin, mebendazole, doxycycline and metformin which are know to target cancer stem cells. I believe you need to try and bock the metabolic pathways of myeloma, or any cancer, and I was diagnosed with myeloma two months after breast cancer so did lots of reading. Jane mcLellands, How to Starve Cancer’ is very informative especially about ‘off label’ (which are cheap drugs), supplements and the importance of diet.
