Investigators Present Initial Results of Two Avinza Trials

April 1, 2005

Ligand Pharmaceuticals has released positive initial results from two studies of the company's pain product Avinza.

In the first study, Avinza (once-a-day morphine sulfate extended-release capsules) showed better control of chronic pain and improved sleep in the initial results from this large comparator study comparing Avinza given once daily to oxycodone CR given twice daily.

A second study demonstrated Avinza's ability to provide better sleep as well as improved pain control for patients with chronic moderate-to-severe osteoarthritis.
