CELEBRATION, Fla., May 15, 2022 (GLOBE NEWSWIRE) -- KemPharm, Inc. (NasdaqGS: KMPH) (KemPharm, or the Company), a specialty pharmaceutical company focused on the discovery and development of novel treatments for rare central nervous system (CNS) diseases, today announced a definitive agreement with Orphazyme A/S (in reconstruction) (ORPHA.CO; ORPH) (Orphazyme) to acquire arimoclomol, an orally-delivered, first-in-class heat shock protein (HSP) amplifier being developed as a treatment for Niemann-Pick disease type C (NPC). NPC is a rare progressive neurodegenerative disease that impacts children, adolescents, and adults, and is characterized by an inability of the body to transport cholesterol and lipids inside of cells, which leads to the abnormal accumulation of these substances within various tissues of the body, including the brain. Arimoclomol is currently being made available to NPC patients in the U.S., France and Germany under Orphazyme’s Early Access Programs (EAP).
Under the terms of the agreement, KemPharm will purchase substantially all of the assets and operations of Orphazyme, including arimoclomol, for a cash payment of USD $12.8 million. The Company expects to finance the cash payment with a revolving line of credit secured by KemPharm’s balance sheet. KemPharm intends to retain the majority of Orphazyme’s current employees. In addition, KemPharm has agreed to assume an estimated reserve liability equal to approximately USD $5.2 million, which is an estimated future rebate due to the French regulatory authorities based on the revenue generated from the EAP in France. For the year ending December 31, 2022, the EAP is expected to generate at least USD $12 million in revenue based upon enrollment in France as of March 2022. The EAP is expected to remain in place until arimoclomol becomes commercially available in each of the current EAP markets. The transaction is expected to close on or before June 1, 2022, subject to customary closing conditions and approval by Orphazyme’s creditors and the Danish bankruptcy court. Canaccord Genuity LLC acted as a strategic advisor to KemPharm for the transaction.
“This strategic acquisition of arimoclomol is a transformative event that significantly expands our rare CNS disease development pipeline, bringing to KemPharm an NDA-stage, revenue-generating product upon which we intend to build commercial capabilities that allow KemPharm to create and retain value for the benefit of shareholders,” stated Richard Pascoe, Executive Chairman of KemPharm. “Moreover, the financial structure of the acquisition combined with the revenue currently being generated by arimoclomol from the early access program in France affords us the opportunity to acquire the asset in a capital efficient manner that has the potential to create positive cash flow, while incurring no shareholder dilution.”
Arimoclomol is administered orally and has been studied in ten Phase 1, four Phase 2, and three pivotal Phase 2/3 trials. Arimoclomol has received Orphan Drug Designation (ODD) for NPC in the United States and the European Union. Arimoclomol has received Fast-Track Designation (FTD), Breakthrough Therapy Designation (BTD), and Rare Pediatric Disease Designation (RPDD) from the FDA for NPC. If approved in the U.S., arimoclomol would also be eligible to receive a Pediatric Priority Review Voucher. On June 17, 2021, Orphazyme received a Complete Response Letter (CRL) from the FDA regarding its NDA for arimoclomol for the treatment of NPC. Orphazyme also withdrew its European Marketing Authorisation Application (MAA) for arimoclomol for the treatment of NPC ahead of a final vote and opinion by the Committee for Medicinal Products for Human Use (CHMP).
“The acquisition of arimoclomol aligns perfectly with our strategy to build KemPharm’s value via the advancement and commercialization of novel treatments that address rare CNS conditions, including our lead clinical candidate, KP1077 in idiopathic hypersomnia,” stated Travis Mickle, Ph.D., President and Chief Executive Officer of KemPharm. “We have carefully evaluated the CRL issued by the FDA and the minutes from the subsequent Type A meeting, as well as the data that has been generated from the development work performed to date. We believe the efficacy signal for arimoclomol in NPC is convincing and that there is a viable regulatory path that could enable a successful NDA resubmission. KemPharm has significant experience with challenging regulatory situations, having successfully led or participated in three FDA product approvals, two of which followed an initial CRL. We welcome the opportunity to work with the FDA on the resubmission of the NDA for arimoclomol in NPC, which we expect to file as early as the first quarter of 2023.”
NPC is a rare progressive lysosomal storage disorder characterized by an inability of the body to transport cholesterol and lipids inside of cells. This leads to dysfunction in organs such as the brain, spleen and liver. NPC can range from a fatal disorder within the first few months after birth (neonatal period) to a late onset, chronic progressive disorder that remains undiagnosed well into adulthood. Disease progression is irreversible in all patients, and loss of neuro-cognitive function adversely impacts their daily life. The mean age of death is 13 years (Bianconi, 2019), and there are no approved treatments for NPC in the United States.
“NPC is an ultra-rare, inherited neurodegenerative disease that affects people of all ages from infancy to adulthood, and leads to progressive impairment of mobility, cognition, speech, and swallowing, culminating in premature death,” said Marc Patterson, MD, Professor of Neurology, Pediatrics and Medical Genetics at Mayo Clinic. “Therapies to treat NPC are desperately needed, and there is hope that a treatment such as arimoclomol could provide a solution to patients around the world who are living daily with the disease. It is encouraging that there is an opportunity to continue the regulatory process for arimoclomol with the FDA.”
