“I was in my early 40s when I was diagnosed with prostate cancer. As a registered nurse caring for men with prostate cancer, I knew I had to make some serious decisions. As part of my treatment, chemotherapy which included Novantrone® offered me as much hope as possible in my fight against this disease. It has now been two years and several months and there is no detectable cancer and I am happy to say that I am feeling good…”

“Eating is something we do every day without thinking about it; however, when going through my chemotherapy treatments the sores in my mouth were so painful, it was difficult to do the simplest of things like swallow. Gelclair® helped me get through my treatments by allowing me to eat and drink…it was an essential part to my recovery.”

   Assembling a Quality Commercial Operation

Around our two marketed oncology products, Novantrone® and Gelclair®, we have now been able to assemble a quality commercial operation in the United States. Obtaining the marketing rights to these products has been an essential step in the process of becoming a fully integrated oncology franchise and allows us to be well prepared for the potential launch of Tarceva™ in the United States.
  
     




Novantrone® is a synthetic antineoplastic anthracenedione used intravenously as an anti-cancer agent. The FDA approved the product in 1987 for acute nonlymphocytic leukemia (ANLL) and in 1996 for the relief of pain associated with hormone-refractory prostate cancer (HRPC), or prostate cancer that no longer responds to hormone therapy. It was also registered for multiple sclerosis (MS) indications in October 2000. In March 2003, OSI entered into an agreement with Serono to market and promote Novantrone® in the oncology marketplace in the United States. To support sales of Novantrone®, the company has built a core commercial operation comprising approximately 60 sales, marketing, medical affairs, commercial planning and support personnel including an approximately 30 person sales force. We have also successfully executed the re-launch of Novantrone® and are actively selling the product across the country. Commissions through our first two quarters of promotion exceeded our estimates and we expect to generate in excess of $30 million in commission revenues in 2004.

 

 


An estimated 300,000 cancer patients in the United States suffer from oral mucositis, an inflammation and ulceration of the surface of the mouth and throat commonly associated with cancer treatment. Patients receiving high-dose chemotherapy and/or radiation therapy often perceive oral mucositis as the
most debilitating toxicity associated with their therapy. In addition, many patients indicate that they receive either no symptom control or only a marginal improvement of their symptoms with current treatment. Symptoms of oral mucositis may include painful ulcerations, redness, and swelling in the mouth. More severe symptoms include extreme pain that may prevent the patient from eating and pose a serious risk of infection resulting in the interruption of cancer therapy. The problem has been a significant unmet need in the management of a cancer patient’s health and well-being.

We obtained our second marketed product, Gelclair®, from our acquisition of Cell Pathways. We believe that Gelclair® could be widely used by oncology patients suffering from chemotherapy- or radiotherapy-induced mucositis, as well as any other patient with mucosal oral lesions. Gelclair® is a bioadherent oral gel indicated for the management and relief of oral pain. It provides rapid and durable oral pain relief by adhering to the mucosal surface of the mouth, forming a protective barrier over the mouth and throat, shielding and soothing the exposed and sensitized nerves. We estimate that the product has the potential to grow to an annual net revenue stream in excess of $25 million per year to OSI over the next five years.

The additions of Novantrone® and Gelclair® to our portfolio represent major steps forward as we continue our mission of building a first-class oncology franchise.
