Taking 250 mg of abiraterone with a low-fat breakfast gives the same PSA response and testosterone suppression as the standard 1,000 mg fasting, because food increases absorption several-fold, so a quarter of the drug treats each man. The label still says fasting and no company promotes the food-effect dose, so adoption is patchy.

A randomised trial at Tata Memorial added nivolumab at 20 mg every three weeks, about one-twelfth of the standard dose, to cheap metronomic chemotherapy for head and neck cancer patients who could not afford full-dose immunotherapy, and they lived longer. Checkpoint inhibitors saturate their target far below approved doses, so publicly funded trials should test low doses in common cancers.

The FDA now requires new cancer drugs to prove their dose is the right one rather than the highest tolerated; asking the same question of the twenty best-selling approved drugs could cut doses, side effects and cost at once.

Pembrolizumab 400 mg every six weeks is approved and works like 200 mg every three weeks, and it halves the number of clinic visits, infusion chairs and travel days without changing the drug bill.

The PERSEPHONE trial showed six months of trastuzumab after surgery is as good as twelve, halving the drug cost; no company will run such trials, so public funders and charities must.

One week of breast radiotherapy in five doses works as well as three weeks in fifteen, but clinics paid per dose lose money by switching; paying one price per course removes the penalty.

Under-the-skin versions of atezolizumab, nivolumab and pembrolizumab take minutes rather than an hour and need no infusion chair, so they can be given by a nurse near home, cutting facility fees and travel.

Weight-based doses rarely match vial sizes, so the leftover is discarded and still billed; closed-system vial sharing and rounding doses to the nearest vial within 10% eliminate most of that waste.
