Orazol™ - Improving the 'Standard of Care' in Bone Metastases

Orazol's weekly oral administration methods

Orazol™ is a weekly oral Zoledronic Acid tablet in phase III development for the treatment of metastatic bone disease.

Developed using Merrion's GIPET® technology, Orazol is a weekly oral tablet dosage, with greatly increased bioavailability, of the market leading I.V. bisphosphonate for bone metastases.

Due to poor bioavailability, the market leading bisphosphonate is currently administered by monthly intravenous infusion. The sales of Zoledronic Acid as an IV infusion were $2.0Bn in 2010.

In Phase II trials Orazol demonstrated several benefits over the current infusion therapy including:

  • Orazol tablet taken weekly had equal efficacy after one week compared with the monthly infusion as measured by standard bone turnover biomarkers (u-NTx, CTX)
  • Improved efficacy for bone pain
  • Improved safety and tolerability profile - Acute Phase Reaction was not observed with weekly Orazol treatment.

In addition to clinical advantages, Orazol offers significant benefits in patient quality of life, patient access, health economics and market expansion opportunities.

Orazol Phase II data demonstrated:
