Pfizer Inc. is to buy Arena Pharmaceuticals Inc. for $6.7 billion, adding a potential follow-up to inflammatory diseases pill Xeljanz (tofacitinib) to its pipeline plus several other potential medicines targeting gastroenterology, dermatology and cardiology.
The U.K.’s Medicines and Healthcare Products Regulatory Agency (MHRA) joined the JAK inhibitor pile-on Oct. 6 with new measures to reduce the risk of major heart problems and malignancies in people taking Pfizer Inc.’s Xeljanz (tofacitinib).
In another cautionary tale for JAK inhibitors, the U.S. FDA is requiring updated boxed warnings for three drugs in the class that are approved to treat inflammatory conditions – Pfizer Inc.’s Xeljanz/Xeljanz XR (tofacitinib), Eli Lilly and Co.’s Olumiant (baricitinib) and Abbvie Inc.’s Rinvoq (upadacitinib).
No matter how effective it is, a drug is worthless if the people who need it can’t afford it. That’s been almost an anthem for patients and policy wonks testifying before U.S. Congress on drug prices.
