New Schiz. Memory Drug in Trials

New Drug Trial for Working Memory Deficits in Schizophrenia;
First ever clinical trial of a full dopamine D1 agonist in schizophrenia


Source: Press Release from DarPharma Pharmaceuticals (see below).

DarPharma announces that enrollment has begun for a trial of DAR-0100 for the treatment of working memory and cognitive deficits associated with schizophrenia. This is the first ever clinical trial of a dopamine D1 receptor full agonist in treating working memory deficits.� The trial is sponsored by The Stanley Medical Research Institute (SMRI) in which Dr. E. Fuller Torrey is an active director, and it is the largest private source of funding for research into schizophrenia and bipolar disease.

"SMRI is dedicated to finding ways to improve the quality of life of people with schizophrenia and bipolar disorder," said Dr. Michael Knable, Executive Director of SMRI and a member of DarPharma's Board of Directors. "This is a rare opportunity to take the exciting science done by Professors Richard Mailman [University of North Carolina, Chapel Hill] and David Nichols [Purdue University] and promising, related science conducted by other investigators throughout the world and translate it into a clinical study that may open new horizons for therapy. We at SMRI are very pleased that we could support this study."

An expert consensus panel convened by the National Institute of Mental Health last year selected D1 agonists as the most promising way to treat working memory deficits in schizophrenia, a major medical problem with significant social and economic costs.

"This is the first clinical study to address the conclusions of the NIMH
experts," said Dr. Prabhavathi Fernandes, President and CEO of DarPharma.

"Professors Mailman and Nichols have invested years towards developing D1 agonists and bringing DarPharma to this point. This trial of DAR-0100 for treating cognitive deficits is a landmark in mental health research."

The trial will enroll patients with schizophrenia who are currently stabilized on existing medications, and will evaluate the effect of DAR-0100 on brain activation using a technique called fMRI, or functional magnetic resonance imaging.� The Medical University of South Carolina is the primary site for the
trial.� Results are expected in the first quarter of 2005.

I was wondering about the dar-0100 I had heard that it can also be used on parkinsons patients is this true my dad has parkinsons and has just begun to shake quite a bit now and it would be great if this could work for him also. I heard that a patient had tried this and it worked for them with the tremors.

Thats very sad. Pharmaceutical therapies truly lag behind research. We actually have made sufficient progress in research, in just the last couple of years, to make drugs that target the underlying abnormalities for this disease. It take over a decade from a discovery to were it actually helps anyone, thanks to the FDA.
