SAN DIEGO, Dec. 20, 2018 (GLOBE NEWSWIRE) -- Retrophin, Inc. (NASDAQ: RTRX) today announced completion of
patient enrollment in the pivotal Phase 3 FORT Study, which is evaluating the safety and efficacy of fosmetpantotenate for the
treatment of pantothenate kinase-associated neurodegeneration (PKAN), a rare, progressive neurodegenerative genetic disorder. The
FORT Study is designed to be registration-enabling in the U.S. and Europe, and top-line results are expected in the third quarter
of 2019.
“Reaching this milestone brings us closer to potentially delivering fosmetpantotenate as the first
disease-modifying therapy to patients with PKAN,” said Noah Rosenberg, M.D., chief medical officer of Retrophin. “We are very
grateful to the PKAN community for their support in raising awareness of this important trial, and we look forward to the readout
of top-line data in the third quarter of 2019.”
The Phase 3 FORT Study is an international, pivotal clinical trial designed to assess the safety and efficacy of
fosmetpantotenate in approximately 82 patients with PKAN aged 6 to 65 years. The primary endpoint of the study is the change from
baseline in the Pantothenate Kinase-Associated Neurodegeneration Activities of Daily Living (PKAN-ADL) scale through 24 weeks of
treatment. After completing the 24-week treatment period, all patients will be eligible to receive fosmetpantotenate as part of an
open-label extension. The FORT Study is being conducted under a Special Protocol Assessment (SPA) agreement, which indicates
concurrence by the U.S. Food and Drug Administration (FDA) that the design of the trial can adequately support the filing of a New
Drug Application (NDA).
About PKAN
PKAN is a rare, genetic and life-threatening neurological disorder characterized by a host of progressively
debilitating symptoms that typically begin in early childhood. People suffering from PKAN may experience movement disorders such as
dystonia (sustained muscle contraction leading to abnormal posture), rigidity, dysphagia (problems swallowing), and twisting and
writhing, as well as visual impairment. PKAN is estimated to affect up to 5,000 people worldwide.
PKAN is caused by a mutation in the PANK2 gene, which encodes a critical protein that phosphorylates vitamin B5
(pantothenate), generating phosphopantothenate. The disruption of this metabolic pathway ultimately leads to decreased levels of
coenzyme A (CoA), which is essential in biochemical reactions impacting energy metabolism, membrane integrity, signaling and other
critical processes.
About Fosmetpantotenate
Fosmetpantotenate is a novel investigational small molecule replacement therapy designed to pass the blood-brain
barrier and be converted to phosphopantothenic acid (PPA). PPA synthesis is a key step in the biosynthesis of CoA. Preclinical
findings suggest fosmetpantotenate has the ability to pass the blood-brain barrier and restore CoA levels.
Fosmetpantotenate, which has the potential to be the first approved treatment targeting the underlying cause of
PKAN, has been granted orphan drug designation for the treatment of PKAN by the FDA and European Commission, as well as Fast Track
status in the U.S. by the FDA. In a Phase 1 study, fosmetpantotenate was found to be generally well-tolerated in healthy volunteers
and it is currently being evaluated in the pivotal Phase 3 FORT Study conducted under a SPA agreement with the FDA.
About Retrophin
Retrophin is a biopharmaceutical company specializing in identifying, developing and delivering life-changing
therapies to people living with rare disease. The Company’s approach centers on its pipeline featuring late-stage assets targeting
rare diseases with significant unmet medical needs, including fosmetpantotenate for pantothenate kinase-associated
neurodegeneration (PKAN), a life-threatening neurological disorder that typically begins in early childhood, and sparsentan for
focal segmental glomerulosclerosis (FSGS) and IgA nephropathy (IgAN), disorders characterized by progressive scarring of the kidney
often leading to end-stage renal disease. Research in additional rare diseases is also underway, including a joint development
arrangement evaluating the potential of CNSA-001 in phenylketonuria (PKU), a rare genetic metabolic condition that can lead to
neurological and behavioral impairment. Retrophin’s R&D efforts are supported by revenues from the Company’s commercial
products Chenodal®, Cholbam® and Thiola®.

guaranteed. Among the factors that could cause actual results to differ materially from those indicated in the forward-looking
statements are risks and uncertainties associated with the Company’s business and finances in general, success of its commercial
products as well as risks and uncertainties associated with the Company's preclinical and clinical stage pipeline. Specifically,
with respect to fosmetpantotenate, the Company faces risk that the Phase 3 clinical trial of fosmetpantotenate will not demonstrate
that fosmetpantotenate is safe or effective or serve as the basis for an NDA filing as planned; risk that fosmetpantotenate will
not be approved for efficacy, safety, regulatory or other reasons, risk associated with enrollment of clinical trials for rare
diseases and risk the clinical trial may not succeed or may be delayed for safety, regulatory or other reasons. The Company faces
risk that it will be unable to raise additional funding that may be required to complete development of any or all of its product
candidates; risk relating to the Company's dependence on contractors for clinical drug supply and commercial manufacturing;
uncertainties relating to patent protection and intellectual property rights of third parties; and risks and uncertainties relating
to competitive products and technological changes that may limit demand for the Company's products. You are cautioned not to place
undue reliance on these forward-looking statements as there are important factors that could cause actual results to differ
materially from those in forward-looking statements, many of which are beyond our control. The Company undertakes no obligation to
