What is NDC 70700-0122?
NDC 70700-0122 identifies a specific drug product approved for commercial distribution. Based on the National Drug Code (NDC) directory, this product corresponds to Xywav (calcium, magnesium, and potassium oxybates), indicated primarily for neurology conditions. The drug was approved by the FDA in July 2020 as an alternative to sodium oxybate (Xyrem), marketed by Jazz Pharmaceuticals.
Market Size and Dynamics
Therapeutic Area and Patient Population
Xywav targets narcolepsy with cataplexy and idiopathic hypersomnia. The treatment landscape includes prior options such as Xyrem, with prevalent off-label uses extending into conditions like obstructive sleep apnea.
- Estimated prevalence of narcolepsy in the U.S.: 135,000 cases.
- Approximate number of patients initiating treatment annually in the U.S.: 10,000.
Competitive Landscape
- Xyrem (sodium oxybate) remains the primary competitor.
- Limited alternatives exist for narcolepsy with cataplexy.
- Other drugs in sleep disorder therapy: modafinil, armamentarium with limited efficacy compared to oxybates.
Market Penetration and Adoption
- Xywav launched in mid-2020; initial penetration was modest, due to prescriber familiarity with Xyrem.
- Rapid growth in prescriptions occurred post-national formulary inclusion and CMS reimbursement adjustments.
- Data from IQVIA suggests prescriptions increased 35% annually during 2021-2022.
