LOS ANGELES, May 2, 2019 /PRNewswire/ -- CytRx Corporation (NASDAQ: CYTR), a biopharmaceutical research and development company specializing principally in oncology, today highlighted that arimoclomol licensee Orphazyme A/S (ORPH.CO) has provided clinical guidance on arimoclomol development milestones through 2021 in its four indications, amyotrophic lateral sclerosis (ALS), sporadic Inclusion Body Myositis (sIBM), Niemann-Pick disease Type C (NPC) and Gaucher Disease.
"The outlook for our arimoclomol licensee Orphazyme A/S is encouraging due to their team's commitment to treating these debilitating diseases," said Eric Curtis, CytRx's President and Chief Operating Officer. "Orphazyme's success would be rewarding to patients worldwide. Should Orphazyme achieve certain clinical milestones with the development of arimoclomol, CytRx would be eligible to receive future milestone and royalty payments from our licensing agreement."
CytRx is eligible to receive $6 million in the U.S. and $4 million in Europe upon approval of arimoclomol in Orphazyme's first non-ALS indication, plus royalties. As previously announced, Orphazyme is engaging with both the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) on path to approval while preparing for filing for Niemann-Pick disease Type C.
The following are Orphazyme's expected pipeline milestones (as stated by Orphazyme):
Niemann-Pick disease Type C (NPC):
- Communication with FDA and EMA on pivotal clinical trial data in NPC – mid-2019
- Regulatory submission of arimoclomol in NPC – 2019
- Approval of arimoclomol in NPC and launch – 2020 and 2021, respectively
Amyotrophic Lateral Sclerosis (ALS):
- Enrollment completion in Phase 3 trial of ALS – H2 2019
- Announcement of Phase 3 results in ALS – H1 2021
- Regulatory submission of arimoclomol in ALS – H2 2021
Inclusion Body Myositis (sIBM):
- Sporadic inclusion body myositis (sIBM) Announced – completion of enrollment in April 2019
- Announcement of interim results of Phase 2/3 trial in sIBM – H1 2020
- Announcement of full data in Phase 2/3 trial in sIBM – H1 2021
- Regulatory submission of arimoclomol in sIBM – H2 2021
- Announcement of results of Phase 2 trial in Gaucher disease – H2 2019
About Niemann-Pick Disease Type C
Niemann-Pick disease Type C (NPC) is a rare, genetic and progressive disease that impairs the ability of the body to move cholesterol and other fatty substances (lipids) inside the cells. The result is an accumulation of lipids within the body's tissue, including the brain tissue, causing damage to the affected areas. The symptoms upon onset of NPC vary from fatality during the first months after birth to a progressive disorder not diagnosed until adulthood. The disease affects neurologic and psychiatric functions as well as various internal organs. Systemic symptoms of NPC are more common in infancy or childhood and the rate of progression is usually much slower in individuals with onset of symptoms during adulthood. NPC is usually fatal and the majority of individuals with the disease die before the age of 20. NPC has been granted Orphan Drug Designation (EU and U.S.) for the treatment of NPC.
It is conservatively estimated that the number of potential NPC patients in the United States and in the EU is between 1,000 and 2,000 individuals in total. Diagnostic challenges may affect the number of potential patients. However, a treatment option could also increase awareness of the disease and assist in identifying more cases.
The rare neuromuscular disease Amyotrophic Lateral Sclerosis (ALS), also called Lou Gehrig's disease, is rapidly progressive and fatal, usually within two to five years. The disease attacks the neurons responsible for controlling muscles leading to paralysis of all skeletal muscles, eventually also affecting breathing, speaking, and swallowing. The cause of damage to the neurons includes protein misfolding and aggregation. Familial and sporadic ALS Approximately 10% of ALS cases are associated with familial ALS, while the rest have no identified genetic component (sporadic ALS). Amongst familial ALS cases, 20% harbor mutations in a SOD1 enzyme. SOD1 ALS is often very aggressive with a life expectancy of less than 2 years from diagnosis. Arimoclomol has so far been tested in two Phase II ALS trials, one dose-ranging trial in sporadic ALS, and one trial in ALS caused by SOD1 mutations.
About Sporadic Inclusion Body Myositis (sIBM)
Sporadic Inclusion Body Myositis (sIBM) is a progressively debilitating muscle-wasting disease. sIBM is characterized by a build-up of protein aggregates and atrophy of muscle cells, which leads to weakness and over time severe disability. The estimated prevalence of sIBM is 24.8-45.6 per million or 17,000-31,000 patients in the USA and Europe. There are no approved treatments for sIBM. Arimoclomol has been granted Orphan Drug Designation (EU and USA) for the treatment of sIBM.
About Gaucher Disease
Gaucher disease is an inherited metabolic disorder caused by mutations in a protein called glucocerebrosidase, which leads to the accumulation of certain sugar-containing lipids. The usual symptoms of Gaucher disease include an abnormally enlarged liver and/or spleen (hepatosplenomegaly), low levels of circulating red blood cells (anemia), blood cells promoting clotting (thrombocytopenia), and skeletal abnormalities. Disease of the nervous system is observed in a significant subpopulation of Gaucher disease (neuropathic Gaucher). There are three types of Gaucher disease, type II being the most severe.
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.
