Polarean's side

Drug makers pay for the clinical trials that take a compound from the lab to FDA approval, and they pay royalties on licensed patents. Those terms are not public. Separately, Polarean received $750K in federal contracts and grants since fiscal 2020, which includes purchases. Polarean's page shows its other products on this list, its federal awards, its PAC's giving and its lobbying. If Polarean wants to add its account, we will publish it here.

How this is built. A product is listed for one of two public records. Either NIH's Technology Transfer office lists it as an FDA-approved product built on a license from an NIH, CDC or FDA lab, or a patent the FDA lists for the drug was reported to NIH as an invention made with NIH grant money, as the Bayh-Dole Act requires. We then add what Medicare Part D, Part B and Medicaid paid for each product, and for each company, the federal grants and contracts it received, its PAC's donations and its lobbying.

What the numbers mean. Medicare and Medicaid figures are gross spending before the rebates drug makers pay back, which are confidential. Hospital-administered therapies such as CAR-T cell treatments are mostly paid under Medicare Part A and do not appear in these files. "NIH grants" is everything NIH paid on the grants a patent was reported under, from 1985 on; a grant usually paid for more than one invention, so it is not the cost of the drug. Federal contracts include purchases, such as vaccine doses, as well as research. Companies also paid for the clinical trials that took these products to approval. None of these figures shows that public money set a price or bought a decision.
