BELLUS Health announces top-line Phase 3 results of KIACTA™ for the treatment of AA amyloidosis

LAVAL, QC, June 20, 2016 /CNW/ - BELLUS Health Inc. (TSX: BLU) ("BELLUS Health" or the "Company"), a drug development company focused on rare diseases, today announced top-line results from the Phase 3 study of KIACTA™ (eprodisate) for the treatment of AA amyloidosis.

In the study, KIACTA™ did not meet the primary efficacy endpoint in slowing renal function decline. KIACTA™ was shown to be safe and well tolerated over treatment periods of greater than 4 years. Further analysis of the data is ongoing.

"While we are disappointed that the Phase 3 study did not meet the primary efficacy endpoint, the full data set will be assessed to determine the best path forward," said Roberto Bellini, President and Chief Executive Officer of BELLUS Health.

AA amyloidosis is a rare disease secondary to severe chronic inflammation or infection leading to the formation and deposition of amyloid fibrils in organs, often resulting in end-stage renal disease and death. Currently there are no therapies available that target the disease directly.

The confirmatory Phase 3 study of KIACTA™ was a global study across more than 70 sites in more than 25 countries that randomized 261 patients to receive either 800mg dose of KIACTA™ twice daily or placebo. The Phase 3 study was an event driven study that lasted 5 years meeting its completion target of 120 patient events linked to the deterioration of kidney function in January 2016.

A more detailed data set of the KIACTA™ Phase 3 study will be presented July 6 at the XV International Symposium on Amyloidosis


BELLUS Health is partnered with global private equity firm Auven Therapeutics for the development of KIACTA™. Auven Therapeutics acquired the rights to KIACTA™ from the Company in 2010.

About AA Amyloidosis

AA amyloidosis is a deadly condition that progresses from chronic inflammatory diseases such as rheumatoid arthritis. The disease causes a protein called amyloid A to accumulate in major organs, particularly the kidneys, which leads to organ dysfunction, failure, and eventually death.

There is currently no available treatment for AA amyloidosis. A recent commercial assessment study conducted by Navigant Consulting on behalf of Auven Therapeutics and BELLUS Health identified between 10,000 and 15,000 KIACTA™ eligible patients with AA amyloidosis in the United States and Europe.

KIACTA™ has been granted Orphan Drug designation or its equivalent for the treatment of AA amyloidosis in the United States, Europe and Japan, which provide for market exclusivity for a period of seven to ten years once the drug is approved, as well as a reduction in application and review fees.
