July ​10 (Reuters) - ​The U.S. Food and Drug Administration said on Friday it has approved a wearable form of Sanofi's blood cancer drug, Sarclisa, ‌offering multiple myeloma patients a less burdensome alternative to intravenous ⁠infusions.

It is the first cancer drug approved by the FDA that can be delivered through ‌an on-body injector, attached ‌to the skin.

The approval boosts the French drugmaker as new CEO Belén Garijo seeks to address investor concerns about reliance on asthma drug Dupixent, ​its biggest-selling medicine.

The new form of the drug is approved for patients with multiple myeloma — a rare and aggressive blood cancer that starts ⁠in the bone marrow.

Subcutaneous dosing can significantly reduce time spent in infusion centers for patients who ​receive repeated treatment courses, while also easing the strain on oncology clinics and nurses.

The infusions can take up to three ​hours, while the median injection time for ‌the wearable device is 13 minutes, Sanofi has previously said.

An intravenous form of the drug first won FDA approval ⁠in 2020 for some patients with relapsed multiple myeloma. The fresh approval covers all existing U.S. indications for the IV form.

The U.S. list price for the drug ⁠with the on-body injector is $8,796 per vial, Sanofi said. A single-dose vial of the ​IV form starts from $956.10 and can be as much as $4,780.54.

Sarclisa is a type of targeted immunotherapy that binds to myeloma cells, exposing them to an immune system attack. ‌It competes with Johnson & Johnson's Darzalex.

The FDA's approval was based on a late-stage trial that showed Sarclisa delivered through ‌the device worked as well as the IV version.

The drug brought in €588 million ($671.67 ⁠million) in sales in 2025 ‌and analysts expect €710 million ​this year.
