In a bid to blunt competition and address rising drug costs, Sanofi is offering a warranty that will cover the cost for any hospital if a specific medicine fails to work, marking only the second time a major pharmaceutical company has taken such a step.

In this instance, Sanofi designed a warranty program for its Cablivi medication, which is used to treat aTTP, a rare, life-threatening autoimmune blood disorder that is considered a medical emergency. The cost will be refunded for up to six doses for patients who fail to initially respond or up to 12 doses for patients whose condition worsens.


The move comes after Pfizer began offering warranties for two of its medicines, the first of which debuted in August 2021. At the time, the Pfizer effort was the first of its kind in the pharmaceutical industry. Unlike the Sanofi warranty, however, the Pfizer programs offer refunds to patients — not hospitals — if the medicines fail to work sufficiently.
