Aug 28 (Reuters) – Roivant and partner Priovant Therapeutics on Friday set a list price of $35,000 for a 30-day supply of their newly approved ​rare disease drug, Lisraya.

Here are the details:

• The ‌daily pill, which launched immediately after FDA approval, is the first targeted oral treatment for dermatomyositis, a rare condition that causes painful skin rashes and progressive muscle weakness.

• On an ‌analyst ​call on Friday, Priovant CEO Ben ⁠Zimmer said prescribing is ⁠open and the first patient prescriptions have already come in.

• The companies are offering a patient support program that can reduce out-of-pocket costs to $0 for ​eligible patients.

• Roivant CEO Matt Gline estimated the net annual value to the company per patient ⁠on a full year of ⁠therapy to be in the low-to-mid $300,000 range, ​though he cautioned that market adoption is expected to ​build gradually.

• In the trial, patients receiving a ‌daily 30 mg dose of Lisraya, chemically known as brepocitinib, achieved a mean total improvement score of 46.5 after 52 weeks, compared with 31.2 for placebo. The ⁠difference was statistically significant, with benefits seen as early as week four, the companies said.

• Pfizer in 2021 licensed ⁠the drug to ‌Priovant Therapeutics, a joint company it ⁠created with Roivant.

• Roivant owns 71% of ​Priovant, ‌while Pfizer holds a 24% stake.

• ​According to ⁠the National Institutes of Health, dermatomyositis affects fewer than 5,000 people in the U.S.

• The partners expect Lisraya to have U.S. market exclusivity until at least 2039.
