LOS ANGELES, July 22, 2019 /PRNewswire/ -- CytRx Corporation (OTCQB:CYTR), a biopharmaceutical research and development company specializing in oncology, today highlighted that arimoclomol licensee Orphazyme A/S (ORPH.CO) has completed enrollment in its Phase 3 clinical trial evaluating arimoclomol for the treatment of amyotrophic lateral sclerosis (ALS) ahead of schedule.

The Phase 3 trial of arimoclomol for ALS is a 76-week, randomized, placebo-controlled trial being conducted at 30 centers of excellence in North America and Europe. A total of 213 patients have been randomized 2:1 to receive arimoclomol or placebo and up to an additional 18 individuals on stable treatment with edaravone may participate in the U.S.  Patients completing the trial will be offered participation in an open-label extension trial.  Orphazyme anticipates announcing top-line results from the Phase 3 trial in the first half of 2021.

"We continue to be impressed with the progress our partner Orphazyme is making with the clinical development of arimoclomol," commented Eric Curtis, CytRx's President and Chief Operating Officer.  "ALS is a devastating disease with few treatment options currently available, and we remain hopeful that arimoclomol could become a life-changing drug for these patients.  We thank Orphazyme for their commitment to the arimoclomol program and their dedication to this patient population."

In 2011, CytRx sold the rights to arimoclomol to Orphazyme A/S (formerly Orphazyme ApS) in exchange for a one-time, upfront payment of $150,000 (USD) and the right to receive up to a total of $120 million (USD) in milestone payments upon the achievement of certain pre-specified regulatory and business  milestones, as well as royalty payments based on a specified percentage of any net sales of products derived from arimoclomol.  Orphazyme, a public company trading on the Nasdaq Copenhagen exchange, is testing arimoclomol in three additional indications beyond ALS, including Niemann-Pick disease Type C (NPC), Gaucher disease and sporadic Inclusion Body Myositis (sIBM).

In addition, CytRx recently announced that Orphazyme issued positive news on its EMEA meeting on arimoclomol in Niemann-Pick disease type C. Orphazyme is planning to submit its Marketing Authorization Application in the first half of 2020.

CytRx is eligible to receive $6 million upon approval of arimoclomol in the U.S. and $4 million upon approval in Europe in Orphazyme's first non-ALS indication, plus royalties on net sales in both territories.

About Arimoclomol

Arimoclomol is an investigational drug candidate that amplifies the production of heat-shock proteins (HSPs). HSPs can rescue defective misfolded proteins, clear protein aggregates, and improve the function of lysosomes. Arimoclomol is administered orally, crosses the blood brain barrier, and has been studied in seven Phase 1 and three Phase 2 clinical trials. Arimoclomol is in clinical development at Orphazyme for the treatment of Niemann-Pick disease Type C, Gaucher disease, sporadic Inclusion Body Myositis, and amyotrophic lateral sclerosis.

About ALS

Amyotrophic Lateral Sclerosis (ALS) is a rare, rapidly progressive, and always fatal neurodegenerative disease. Protein misfolding and aggregation in motor neurons are important contributors to the disease process, which ultimately leads to paralysis of skeletal muscles as well as the muscles that enable breathing. The patient population in Europe and the United States is estimated to be approximately 50,000. Currently, there are only limited treatment options available. Arimoclomol has been granted Orphan Drug Designation (EU and USA) for the treatment of ALS.
