Ironshore Pharmaceuticals Announces PDUFA Date of August 8, 2018 for HLD200

GEORGE TOWN, Grand Cayman–(BUSINESS WIRE)–Ironshore Pharmaceuticals & Development, Inc. (“Ironshore”), a wholly
owned subsidiary of Highland Therapeutics Inc., today announced that the
U.S. Food and Drug Administration (FDA) has accepted the resubmission of
the New Drug Application (NDA) for HLD200, Ironshore’s lead compound
currently under review as a new treatment for Attention Deficit
Hyperactivity Disorder (ADHD) and set a Prescription Drug User Fee Act
(PDUFA) date of August 8, 2018.

HLD200 is a delayed-release and extended-release formulation of
methylphenidate which was developed to be dosed at night to target an
onset of effect in the morning. HLD200 was developed over a 10-year
period and the NDA contains data from nine trials including two pivotal
Phase-3 studies. In both studies, HLD200 achieved statistically
significant improvements in symptoms associated with ADHD on each of the
endpoints evaluated.

HLD200 is the first product that leverages Ironshore’s DELEXIS®
technology platform which could have a meaningful impact on health
outcomes in a variety of therapeutic areas including, among others,
central nervous system disorders and inflammatory bowel disease.

While the NDA resubmission for HLD200 has been accepted for review by
the FDA, such acceptance does not mean that HLD200 will be approved by
the FDA for the treatment of ADHD.
