Auven Therapeutics and Bellus Health Announce Engagement of Financial Advisor to Explore Sale of KIACTA™, an Experimental Drug in Phase III Development for the Treatment of AA Amyloidosis

Auven Therapeutics and BELLUS Health Amend the KIACTA™ Asset Purchase and Licensing Agreement

New York, USA and Laval, Canada - May 7, 2014 – Auven Therapeutics, the global private equity company focused on accelerated development of breakthrough therapeutic drugs and BELLUS Health Inc. (TSX:BLU), a drug development company focused on rare diseases, today announced that Lazard has been engaged as financial advisors to explore the sale of KIACTA™, an orphan drug nearing completion of its confirmatory Phase III trial as a treatment for AA Amyloidosis.  Auven and BELLUS Health also have amended the asset purchase and license agreement related to KIACTA™ (eprodisate disodium) in order to facilitate a potential sale of KIACTA™.

“We intended to complete the Phase III confirmatory study before offering KIACTA™ for sale,” said Stephen Evans-Freke, co-founder and Managing General Partner of Auven Therapeutics.  “However, we have received a number of indications of strong interest from prospective buyers keen to have sufficient lead time to prepare for a global launch. Therefore, it makes sense to facilitate this step by modifying our agreement with BELLUS Health, and to appoint an advisor to explore sale options.”

“This new direction and amended agreement provide more flexibility to divest KIACTA™ at the most opportune moment for stakeholders, whether that proves to be this year or after the conclusion of the KIACTA™ Phase III registration trial,” said Roberto Bellini, President and Chief Executive Officer of BELLUS Health.

Auven Therapeutics acquired worldwide rights related to KIACTA™ from BELLUS Health in 2010 and assumed control of the KIACTA™ development program and related activities, including the registrational Phase III clinical study in AA Amyloidosis. Auven and BELLUS Health have now agreed upon modified terms to share the proceeds from a divestiture of KIACTA™ particularly in the now-envisaged scenario of a KIACTA™ sale before the completion of its Phase III trial.

Assuming that total divestiture transaction proceeds reach a pre-determined threshold, the parties will share aggregate proceeds equally. Auven retains certain preference rights on exit proceeds related to Auven’s aggregate investment in KIACTA™ up to the date of the sale.

As the Phase III KIACTA™ trial in AA Amyloidosis nears completion of its enrollment, Auven has determined that a potential sale now would provide the acquirer with the opportunity to have input into the regulatory process for approval of KIACTA™ worldwide, and would facilitate the manufacturing, marketing and sales preparations for a global launch of the drug.

KIACTA™ is an orally bioavailable small molecule that is being developed for the treatment of AA amyloidosis, a rare disease resulting from chronic inflammatory conditions that often rapidly leads to renal failure, dialysis and death. The Phase III study is designed to confirm the safety and efficacy of KIACTA™, previously demonstrated in a phase II/III study, in preventing kidney function decline in patients diagnosed with AA amyloidosis. A recent commercial assessment study conducted for Auven and BELLUS Health indicated that there are approximately 13,000 diagnosed and addressable patients with AA Amyloidosis worldwide, of which an estimated 10,300 are in the U.S and the EU5. The incidence of AA Amyloidosis is higher in the Middle East and certain other countries where it is associated frequently with Familial Mediterranean Fever.

“The data from the earlier Phase II/III trial prior to our acquisition of KIACTA™ established with statistical significance that it is both safe and effective in the treatment of this often lethal disease, delaying AA amyloidosis disease progression based on a composite endpoint of renal function deterioration and death,” said Dr. Peter B. Corr, Co-Founder and Managing General Partner of Auven Therapeutics. “This confirmatory and registrational Phase III study is enrolling 230 patients at 70 sites in 30 countries around the world, and we expect it to conclude within two years. We are optimistic as we enter the final stages that the study will confirm the prior results, so it is appropriate to explore a sale process at this time.”
