Capricor Therapeutics accused Nippon Shinyaku and its U.S. subsidiary of failing to follow through on marketing plans for a Duchenne muscular dystrophy treatment, and refusing to fix a pricing glitch that was belatedly discovered in their exclusive distribution agreement.
A key issue is a “fatal flaw” in a pricing formula that would make it “economically impracticable” for the therapy to reach patients covered by Medicare, Medicaid, and private insurers, according to a lawsuit filed in a New Jersey state court on Thursday. Nippon Shinyaku and NS Pharma, the subsidiary, disclosed the problem in March 2025.
Basically, the formula ties Medicare reimbursement to the price that Capricor would charge NS Pharma, since it would be the only U.S. buyer. But as it stands, the lawsuit indicated that health care providers would get reimbursed less than they would pay to cover the cost of acquiring and administering the medicine, which is called deramiocel.
