Orazol™ - The New Indication Improving Outcomes in Breast CancerOrazol™ - The New Indication Improving Outcomes in Breast Cancer

  • Blockbuster Drug
  • Demonstrated Clinical Efficacy
  • Fast Route to Market - Single Phase III Study, 18 months treatment
  • Large Patient Population
  • Patent Protected until 2027
  • Chronic Therapy, Branded Pricing

Orazol™ is a unique weekly tablet formulation of zoledronic acid designed to provide the same dose as a monthly infusion.

Following consultation with the FDA, Merrion has a defined regulatory pathway for its Phase III programme for Orazol. The Phase III study in approximately 1,000 subjects should allow Orazol to be approved under the FDA's abbreviated section 505(b)(2) procedure using a single Phase III Study. The study will compare Orazol against placebo as an adjuvant breast cancer treatment with a primary endpoint of Disease Free Survival of patients with breast cancer.

Adjuvant breast cancer therapy is the long term treatment of patients aimed at preventing cancer reoccurrence and progression and increasing overall survival. In the US alone, 600,000 patients annually undergo adjuvant breast cancer therapy.

Early stage breast cancer is a multibillion dollar market with limited new treatment options. Orazol is a high potential, late stage licensing opportunity as a potential blockbuster product with an abbreviated development path, limited clinical risk and issued US patent protection to 2027.

Established Clinical Efficacy

Extensive data from large scale trials (Azure Trial and ABSCG- 12) have demonstrated that the addition of zoledronic acid to standard therapy has a statistically significant clinical benefit, 21% reduction in risk of reoccurrence and 29% increase in overall survival (Azure - post menopausal patients) and 35% reduction in risk of reoccurrence and 36% reduction in risk of progression (ABSCG-12 premenopausal patients with medically reduced estrogen levels).

Orazol offers a significant commercial opportunity as a multi year treatment to reduce risk of cancer progression or recurrence and increase overall survival. Orazol presents a unique market opportunity in the postmenopausal breast cancer population addressing key unmet needs, with a defined regulatory pathway and limited clinical risk, as there is extensive phase III data from large scale zoledronic acid studies supporting its anti-cancer effect.

Developed using Merrion's proprietary GIPET Technology, Orazol provides an ideal product profile to achieve high market penetration, as a well tolerated tablet formulation with weekly dosing.
