CEO COMMENTS

All eyes on Diamyd

Diamyd Medical is currently experiencing an exceptionally intensive period with extremely high expectations on the company, both internally and externally. In mid-February, the last patient made the final visit in the 15-month main trial period in the company's European Phase III trial. Participants in the study are being treated with the antigen-based candidate drug Diamyd^® or placebo to assess whether it is possible to preserve beta cell function and thus improve management of blood sugar control long term among children and adolescents with recent-onset type 1 diabetes. Extensive efforts are currently underway to compile and process all the data. This is a comprehensive and time-consuming undertaking and, as previously announced, we expect to be able to report the top line results from the study in the late spring.

This is a particularly important period; not just for Diamyd, but my immediate thoughts go to all the children and adolescents with diabetes participating in the study, as well as all the physicians and nurses performing the trial. We should also not lose sight of the great importance of the results for diabetes research worldwide. If we could show that it is possible to preserve beta cell function in recent-onset type 1 diabetes, it would represent a breakthrough that we have not seen since insulin was introduced in the 1920´s. 

Several important events have taken place in the past quarter. At year-end, Diamyd Medical (DIAM B) moved from the Small Cap list to the Mid Cap list on the NASDAQ OMX Stockholm. The interest in our company remains very high and we currently have more than 6,000 shareholders, which we are very proud of.

The pace is also quickening in the Pain business area. In January, we initiated a US Phase II trial aimed at testing the NP2 Enkephalin candidate drug's potential to relieve cancer pain. Some 32 patients with severe cancer pain are currently being enrolled in the study. Recently the interest in Diamyd's unique method of treating pain was further confirmed with the publication of the results of our Phase I trial with NP2 Enkephalin in the medical journal Annals of Neurology. As announced earlier, we also intend to launch a clinical study with the NG2 GAD candidate drug in patients with chronic neuropathic pain in 2011.

The upcoming period will possibly be the most significant in Diamyd's history when the results of the Phase III study are reported. We hope our results will be the main topic of conversation at the important diabetes meeting, the American Diabetes Association's 71st Scientific Sessions, which this year takes place in San Diego at the end of June. We have an incredibly exciting and intense time ahead of us.

SIGNIFICANT EVENTS DURING THE REPORTING PERIOD

DECEMBER 1, 2010 - FEBRUARY 28, 2011  

Last patient completed the EU Phase III study of Diamyd^® antigen based therapy for type 1 diabetes. The last patient in the EU Diamyd Medical Phase III clinical study completed the 15-month visit in February. This important achievement in the Diamyd^® Phase III program is now being followed by an intense period where the data from the more than 60 clinics throughout Europe and from the central laboratory is compiled and processed. The top line results are expected to be reported as planned, in late spring 2011.

University of Florida Research Foundation initiated court case against Diamyd Medical. The University of Florida Research Foundation (UFRF) filed a lawsuit in United States federal district court in Florida against Diamyd Medical claiming that UFRF is entitled to a percentage of the license fee paid to Diamyd Medical by Ortho-McNeil-Jansen Pharmaceuticals, Inc. (OMJPI). Diamyd Medical has licensed certain rights from UFRF, and these rights were among the rights that Diamyd Medical sublicensed to OMJPI.

Diamyd Medical started Phase II study in cancer pain. The Phase II clinical trial, with the candidate drug NP2 Enkephalin, started in January 2011 the recruitment of approximately 32 subjects with severe cancer pain. Their pain scores and concomitant pain medication usage will be followed. It is a multi-center, randomized, double-blind, placebo controlled study designed to provide a statistical evaluation of pain relief. The trial has a four week double-blind main study period and following this period, all patients will be offered up to two additional doses of active NP2 Enkephalin in an open label study extension.

The Diamyd share moved to NASDAQ OMX Stockholm Mid Cap list. NASDAQ OMX Stockholm decided to move Diamyd Medical (DIAM B) from the Small Cap list to the Mid Cap list. The change was effective as of January 3, 2011. The Mid Cap segment includes companies with a market capitalization of between EUR 150 million and EUR 1 billion.

NASDAQ OMX Stockholm Disciplinary Committee imposed a penalty on Diamyd Medical AB for inadequate disclosure of information. In a letter dated November 5, 2010 to the Disciplinary Committee of NASDAQ OMX Stockholm, NASDAQ OMX Stockholm AB requested that the Disciplinary Committee issue a decision on disciplinary action regarding Diamyd Medical AB's disclosure of information.
