Acerus Announces Reporting of Anticipated Shortage of ESTRACE®

TORONTO–(BUSINESS WIRE)–Acerus Pharmaceuticals Corporation (TSX: ASP) (“Acerus” or the
“Company”) is today advising that it has reported an anticipated
shortage of certain doses of ESTRACE® on the Drug Shortages
Canada website in relation to supply issues arising from the Company’s
contract manufacturer.

The Company had previously been notified by its contract manufacturer of
a partial manufacturing license suspension at the facility where ESTRACE®
is being produced as a result of an audit by U.K. health authorities.
The manufacturer expected that the manufacturing license would be
reinstated by December 2018 in time to avoid delivery delays. The
Company was notified this week that such manufacturing license
reinstatement has not yet occurred and that, as such, the Company’s next
expected shipment of ESTRACE® may be delayed. This may lead
to potential shortages of the 0.5 mg and 1.0 mg doses of ESTRACE®
within the next six months as forecasted demand may exceed in-stock
inventory. At this time, the Company does not foresee a shortfall of the
2.0 mg dose in the next six months based on existing inventory in stock.
The Company is working with the manufacturer to accelerate delivery
timelines, but it is unclear at this time if supply will be
re-established in time to avoid shortages.

“We are disappointed that we potentially face a shortfall of supply of
ESTRACE®,” said Ed Gudaitis, President and CEO of Acerus
Pharmaceuticals. “We will be working diligently with all parties to
mitigate the impact of this issue with the goal that a steady supply of
ESTRACE® is once again available as soon as possible.
However, should shortages occur or persist, this may have an ongoing
negative impact on ESTRACE® revenues.”
