Scilex Holding Company announces the U.S. FDA has approved the sNDA for commercial manufacturing of Gloperba® which will be launched in the US in the week of June 10th 2024


  • Gloperba® is the first and only liquid oral version of the anti-gout medicine colchicine indicated for the prophylaxis of painful gout flares in adults.
  • Gout is a painful arthritic disorder affecting an estimated 9.2 million people in the United States1. As gout cases increase every year, treatment requirements increase. The gout treatment market is projected to be $2.0 billion in the U.S. by 2028 with a well-defined area of unmet need.2
  • Over 70% of gout patients have comorbid conditions that may require dose adjustments and such patients could be a potential target population for Gloperba®3
  • Over 17% of gout patients on colchicine experienced severe gastrointestinal side effects like diarrhea. These patients may benefit from flexible dosing offered by Gloperba®4
  • Scilex is well-positioned to market and distribute its third commercial non-opioid product, Gloperba®:
    • Scilex has a direct distribution network to national and regional wholesalers and pharmacies throughout the U.S.
    • Scilex has an experienced commercial and managed care team that has successfully launched and grown market access for ZTlido® (lidocaine topical system) 1.8% to more than 225 million covered lives in the U.S. as well as successfully launching Elyxyb® (celecoxib oral solution) in the U.S. in April 2023, the only FDA-approved ready-to-use oral solution for the acute treatment of migraine, with or without aura, in adults.

PALO ALTO, Calif., June 06, 2024 (GLOBE NEWSWIRE) — Scilex Holding Company (Nasdaq: SCLX, “Scilex” or “Company”), an innovative revenue-generating company focused on acquiring, developing and commercializing non-opioid pain management products for the treatment of acute and chronic pain, today announced that it has the FDA approval of commercial manufacturing of Gloperba®, an FDA-approved prophylactic treatment for painful gout flares in adults, in the U.S. and will launch in June 2024. Scilex will stock Gloperba® in all major wholesalers and pharmacies starting June 10, 2024.

Gloperba® is a highly complementary commercial asset that allows the Company to provide physicians with another tool in their non-opioid pain management armamentarium to treat gout earlier in the patient journey as the Company continues to work towards re-defining the role of opioids as a last resort rescue medication.


Gloperba® is a novel liquid colchicine formulation with a launch price of $595 per 150ml bottle.  Gloperba® is the only FDA approved liquid formulation of colchicine for the prophylaxis of acute gout flares. Over 70% of gout patients have chronic kidney disease and many suffer from gastrointestinal sensitivity, necessitating a lower dose of colchicine than the standard 0.6 mg tablet or capsule. Gloperba® is expected to be the first liquid colchicine formulation that allows healthcare providers to prescribe precision dosing in at-risk patient populations, and thereby help mitigate against severe toxicity in patients. Healthcare providers can now safely and effectively manage such patients at doses below 0.6 mg once or twice daily, which is the standard dose for prophylaxis. In patients who are treated at lower doses than 0.6 mg, the 150 ml bottle of Gloperba® is expected to last more than 30 days, delivering additional value to patients.

A recent market research study among rheumatologists conducted by Scilex revealed a high degree of interest in Gloperba® as a liquid colchicine formulation designed for precision dosing.5 Specifically, clinicians using colchicine for prophylaxis of gout flares in adults indicated a strong likelihood to use Gloperba® instead of tablets/capsules in certain at-risk patient populations who have a clinical need for lowered precision dosing to mitigate the risk of colchicine toxicity. Notably, the American College of Rheumatology (ACR) guidelines also reflect this need.6
