The clinical trial report includes data from the four week observation period following one single administration of NP2, delivering Enkephalin, an opioid peptide, specifically to nerves experiencing pain from cancer. The clinical trial enrolled patients that were in chronic pain despite taking maximum tolerated doses of standard pain medications. NP2 Enkephalin is the first drug candidate from the company's proprietary NTDDS (Nerve Targeting Drug Delivery System) platform focally delivering therapeutic compounds directly to the nervous system.

"We are excited to report prolonged pain relief in this patient population with serious unmet medical need. It is gratifying for our entire team to have taken NP2 Enkephalin and the NTDDS platform from the bench to the bedside and report these encouraging results", states Darren Wolfe, CEO of Diamyd Inc., the US subsidiary of Diamyd Medical responsible for the development of the NTDDS platform.

"This is laying the ground work for our pipeline of products for treatment of chronic pain. We will continue to develop NP2 Enkephalin and explore additional pain treatment applications for the NTDDS platform", says Elisabeth Lindner, CEO and President of Diamyd Medical.

The Phase I study is intended to test the safety of NP2 Enkephalin and the NTDDS platform. In addition to safety, measurements of pain relief and concomitant pain medications were collected. The clinical trial was designed as an open label, dose escalation study in patients with intractable pain due to cancer. Three dose levels were investigated and eight patients were evaluable at the four week time point. The patients will be followed for an additional three months after which a final report will be prepared. To verify the positive outcome of the Phase I study, the company is planning a multi-center placebo controlled Phase II proof-of-concept study with NP2 Enkephalin in the United States.

In addition to NP2 Enkephalin, Diamyd is developing two other NTDDS projects, NG2 GAD and NE2 Endomorphin, which are both promising for the treatment of pain. All three drug candidates demonstrate significant pain relief in preclinical models as published in peer reviewed scientific publications. The candidate drugs encompass treatment therapies that naturally target the body's three major pain pathways, creating good prospects for the further development of a competitive product portfolio in the area of pain.
