1) Pharmaceuticals Update

Neurochem reports promising findings from Alzhemed study

Neurochem (Montreal) announced a preliminary analysis of the data from its recently completed Phase II clinical trial for the investigational drug candidate, Alzhemed, in patients with mild-to-moderate Alzheimer’s disease (AD). The study revealed promising results for both the primary and secondary objectives of the trial. There were no safety findings of concern in patients treated with Alzhemed. The pharmacokinetic profile of Alzhemed has been well characterized and it was detected in the cerebrospinal fluid (CSF) of the patients, suggesting an ability to cross the blood brain barrier. Patients with the greatest decrease in amyloid protein in the CSF were all on Alzhemed. Furthermore, the majority of patients on the highest dose of Alzhemed showed, at the six-month time point of the ongoing open-label extension study, stable results on cognitive function test (as measured by the ADAS-Cog.

Biovail announces receipt of an approvable letter for Wellbutrin

Biovail Corporation (Toronto) announced that the US Food and Drug Administration has issued an approvable letter for the once-daily antidepressant Wellbutrin XL (bupropion hydrochloride extended-release tablets) developed for the treatment of major depressive disorder in patients aged 18 and older. The approvable letter involves resolution of routine matters and consequently, approval of Wellbutrin XL is still expected during the second half of 2003. Responses to these routine matters are being prepared expeditiously and are expected to be submitted to the FDA promptly.

Positive clinical results for INEX application for Onco TCS

Inex Pharmaceuticals (Vancouver) said that data from all 119 patients treated in the pivotal phase II/III clinical trial evaluating its lead anticancer product Onco TCS as a single-agent therapy for relapsed aggressive non-Hodgkin’s lymphoma (NHL) confirms the positive results of the first 102 patients released in December 2002. David Main, INEX president and CEO, said the complete pivotal trial results will form the basis of a new drug application (NDA) that will be filed late in the third quarter or early in the fourth quarter of this year to seek regulatory marketing approval from the US Food and Drug Administration (FDA). Prior to enrollment in this study, the 119 patients had received on average four other therapies and 72% had disease that was “resistant” to their last treatment. After treatment with Onco TCS, the overall response rate was 25%, including seven patients (6% of patients) whose tumors were completely eliminated and 23 patients (19% of patients) whose tumor volume was reduced by more than 50%. An additional 31 patients (26% of patients) had their disease stabilized while being treated with Onco TCS.

2) Diagnostics and Therapeutics Update

Stem cells trigger regeneration of damaged organs

Canadian scientists have discovered that stem cells can trigger regeneration of severely damaged organs in animals, a feat that suggests it might be possible to trick the human body into healing itself. Scientists at the Robarts Research Institute in London, Ontario, injected bone marrow stem cells into diabetic mice, which were cured or back to normal within seven to 14 days. Further, the stem cells triggered the rodents’ damaged pancreases to regenerate on their own. It is not clear how the stem cells triggered the regeneration in mice, but the scientists suspect the stem cells might produce potent molecules.

MRSA clinical studies start on new screening test

Infectio Diagnostic (Quebec City) has completed development of a new ultra-rapid screening test for the extremely virulent methicillin-resistant Staphylococcus aureus (MRSA). Clinical studies are just underway and may be completed by the fall. Results will then be submitted to the Food and Drug Administration (FDA) in the US and to Health Canada for approval. IDI is looking to market its product by the end of the year. This test will enable detection of MRSA in under one hour, whereas the existing method, involving a bacterial culture, can take up to two or three days. “There is a potential here of enormous savings for the health system,” predicts Mr Jacques Milette, Vice president, sales and business development for IDI.

Cangene enters partnership to develop hyperimmunes related to SARS

Cangene (Toronto) announced that it has signed a memorandum of understanding with Health Canada’s National Microbiology Laboratory to further public health research into Severe Acute Respiratory Syndrome. The agreement will facilitate the development of a hyperimmune globulin from plasma obtained from recovered SARS patients. This hyperimmune may result in diagnostic and therapeutic agents for use in the treatment of SARS. Toronto-based physicians with the support of patient donors first proposed this initiative.

Study identifies stem cells responsible for regenerating damaged muscle

A research team from the Ottawa Health Research Institute, led by Dr Michael Rudnicki, has published a groundbreaking study that demonstrates how a novel population of adult stem cells resident in muscle tissue plays an important role in muscle regeneration. For the first time, the research also identifies details of the molecular signals that direct these adult stem cells to form new muscle, offering hope for millions of people with neuromuscular disorders. The Rudnicki team’s findings are published in the June 27 issue of the prestigious scientific journal Cell. This landmark research shows that a class of adult muscle stem cells, called CD45+ cells, plays a natural role in regeneration when they receive signals in the form of a secreted protein known as Wnt. Wnt proteins are secreted in response to tissue damage and act to trigger the stem cells to divide and then develop into highly specialized muscle cells. A focus of future research will be to develop drugs that target the Wnt signaling pathway as new treatments for neuromuscular diseases and muscle injury.

3) Medical Devices
