BELLUS Health Inc. has announced that, on March 30, 2010, the Company initiated a Phase I clinical study for NRM8499, a prodrug of tramiprosate. NRM8499 is intended for the treatment of Alzheimer's disease. The randomized, double-blind, placebo-controlled study will investigate the safety, tolerability and pharmacokinetic profile of NRM8499 in a group of up to 84 young and elderly healthy subjects.

BELLUS Health announces launch of NRM8499 Phase I clinical study for the treatment of Alzheimer's disease
LAVAL, QC, April 1 /CNW Telbec/ - BELLUS Health Inc. (TSX: BLU) ("BELLUS Health" or the "Company") announced today that, on March 30, 2010, the Company initiated a Phase I clinical study for NRM8499, a prodrug of tramiprosate. NRM8499 is intended for the treatment of Alzheimer's disease. The randomized, double-blind, placebo-controlled study will investigate the safety, tolerability and pharmacokinetic profile of NRM8499 in a group of up to 84 young and elderly healthy subjects.
NRM8499 was previously identified by BELLUS Health as a compound which increases the brain exposure to tramiprosate. Preclinical studies conducted in rodents showed that NRM8499 increased plasma and brain exposure to tramiprosate by 1.5 to 3 fold. The Company believes that an increase in the exposure of tramiprosate to the brain may help improve the therapeutic effect on cognitive function and other clinical outcomes in Alzheimer's disease.
"We are very excited about the launch of the NRM8499 Phase I clinical study. The knowledge acquired through the tramiprosate development program concerning this compound, along with our enhanced understanding of Alzheimer's disease acquired through more than 15 years of preclinical and clinical research in this field, leads us to believe that the potential for NRM8499 is extremely promising," said Roberto Bellini, President and Chief Executive Officer of BELLUS Health. "We are looking forward to the results of the study which could eventually lead to the development of the first disease-modifying treatment for Alzheimer's disease," he concluded.
Entitled "A Phase I, Single-Center, Double-Blind, Randomized, Placebo-Controlled Clinical Trial to Investigate the Safety, Tolerability and Pharmacokinetics of NRM8499 Administered as Single and Multiple Oral Doses to Healthy Young Males and Healthy Elderly Male and Female Subjects", the study will be divided in four parts:
- The first part will compare the safety, tolerability and
pharmacokinetic of NRM8499 following a single oral administration in
both young and elderly healthy subjects, to those of tramiprosate in
the same conditions.
- The second part will assess the safety, tolerability and
pharmacokinetic of up to four single ascending oral doses of NRM8499 in
healthy elderly subjects.
- The third part will investigate the effect of food on the safety,
tolerability and pharmacokinetics of NRM8499 following a single oral
administration in healthy elderly subjects.
- Finally, the fourth part of the study will evaluate the safety,
tolerability and pharmacokinetic profile of up to three multiple
ascending oral doses of NRM8499 in healthy elderly subjects.
NRM8499 has shown a benign safety profile in preclinical toxicity studies. The NRM8499 Phase I clinical study is expected to conclude in the second half of 2010.
