What the date means

Pomalyst's US exclusivity date is based on generics launched. US generics have already launched, so the loss of exclusivity is under way. It is a small-molecule drug, so copies are generics. Generic launches usually take most of the US volume within months.

Medicare price negotiation

Pomalyst was selected for the Medicare Drug Price Negotiation Program. Its negotiated Medicare price takes effect in 2027, 60% below its list price. US generics had already launched by then. The discount is measured against list price, before the rebates drugmakers already pay, and applies to Medicare only, so the revenue impact is smaller than the headline number.
