CEO’s comments

The United States consume 80 percent of the world’s opioids, but only account for 4.6 percent of the world’s population and the amount of opioid painkillers prescribed is enough to medicate every single adult in the country for one month. The consequences, when opioids are abused, on the society is severe and in 2014, 28,647 people died from drug overdose with opioids[1] (http://connect.ne.cision.com#_ftn1) in the US. This a tripling since year 2000 and has created an outcry in major media in the US e.g. the cover page of the first Newsweek® of 2016 read "Why Are White Americans Dying Younger?”, with the answer being the prescription opioid epidemic.

Since the initiation of our commercial journey for Zubsolv®, we have highlighted the significant unmet need for opioid dependence treatment. More than 10 million Americans are using opioids for non-medical purposes and less than 1 million receiving any type of treatment today. The need for actions from the authorities in the United States is imminent and this was one of the first topics raised by President Obama in his final State of the Union speech. We know several concrete improvements are being evaluated, one being how to double the amount of prescribers in this disease space (2). We have anticipated this type of change and it has been an integral part of our business plans since we decided to establish a commercial entity in the US. Two years into our commercial journey in the US, we finally see concrete steps in the right direction for the patients and for Orexo and this give me strong confidence in the journey have ahead of us.

In a market facing dramatic changes, being at the forefront in terms of scientific documentation and developing a product range, providing the optimal convenience and flexibility for patients and physicians are important competitive differentiators. Thus, I am happy to report our registry study REZOLV is about to finalize the patient recruitment with more than 1,000 patients enrolled by the end of 2015. Also our product development has progressed and we launched two new tablet strengths in the fourth quarter. However, when I met physicians during the launch of these new tablets, they inquired about a tablet with lower strength to improve their ability to tapering down with Zubsolv. Thus, I am pleased to report that we have filed for approval a new lower dosage in Q4, 2015 and we anticipate FDA approval in Q4, 2016.

While we continue to invest in the growth of Zubsolv, we also continuously assess where and how to optimize the use of our resources. As a reaction to the change in market access from January 1, 2016 we have made an adjustment in the sales force in selected geographies. This will increase efficiency and enable a focus where our presence has the highest return on investment potential. One such region is the State of New York where we won an exclusive regional contract to be implemented in March 2016. We will ensure we have sufficient resources in this region to optimize the value of this contract. Another important driver of the profitability of our commercial investments, is the price and I am pleased to report we have been able to increase the price of Zubsolv in January 2016.

Our efforts to find a partner for Zubsolv outside the US and for our project OX-51 continue to progress well. We expect to finalize the full license agreement for Zubsolv outside the US in the first half of 2016. Like we have seen with Abstral® in Europe, the right partner for Zubsolv will further strengthening Orexo’s long term growth opportunities.
