Zymenex gets FDA approval of IND

Zymenex has received FDA approval of its Investigational New Drug (IND)

application for its enzyme Metazym, which is intended for use in the treatment of the

rare, lysosomal disease Metachromatic Leukodystrophy (MLD). The company is now

preparing for Phase 2 clinical trials in the USA.

“This milestone is very important and paves the way towards a treatment for the

patients in the USA suffering from this lethal disease,” says CEO Jens Fogh,

Zymenex A/S.

The Phase 2 trial will include 10 patients with late-infantile MLD and will be

performed by Dr. Maria L. Escolar at the Program for Neurodevelopmental Function

in Rare Disorders, Center for the Study of Development and Learning, University of

North Carolina (UNC), Chapel Hill, North Carolina, USA. The FDA IND approval is

the first step towards being able to initiate the trial. The trial protocol must now be

approved by the Ethical Committee at UNC, along with formalizing various

administrative and logistical issues. These processes will take at least 6 months

before the trial can begin.

“We are very excited about the prospect of evaluating a potential new therapy for this

neurologically devastating disease”, says Dr. Escolar.

In Europe, Metazym has been in Phase 2 clinical trials in MLD patients for a year.

Drs Allan M. Lund and Christine i Dali from Rigshospitalet, Copenhagen are

responsible for the trial and the treatment of the patients.

Supplemental information

Metachromatic Leukodystrophy (MLD), is one of 45 diseases within the family of

Lysosomal Storage Diseases.

MLD is caused by an increased concentration of sulphatide in cells and an ensuing

breakdown of “myelin”, a substance that protects the nerves in the brain and the rest

of the body. The disease occurs due to a lack of the enzyme Arylsulfatase A (ASA),

which causes irreparable neurological damage and death. There are no clear

benefits from any other present therapy for children with Late-infantile MLD who are

often diagnosed at the age of two years. Once symptoms become evident they have

rapid neurological deterioration, become bedridden until they die within three to four

years. The disease is rare and therefore unknown to the general public. The disease

can in some ways be compared to Multiple Sclerosis, which also exists in several

forms and can have a very quick and lethal progression.

Zymenex A/S has developed Metazym. The company is a Scandinavian

biopharmaceutical company, founded in 1998, with headquarters in Hillerød north of

Copenhagen, Denmark and research laboratories in Stockholm, Sweden. The

company is focused on research and development of pharmaceutical products for the

treatment of rare, genetic diseases, for which there is no treatment today and which,

due to the small patient populations, fall within “Orphan Diseases” and the Orphan

Drug Acts.

Zymenex has two other projects for Orphan Diseases in the development pipeline;

Lamazym for Alpha-mannosidosis and Galaczym for Globoid Cell Leukodystrophy

(Krabbe Disease).

Zymenex is supported financially by the Danish venture capital investors

BankInvest and Sunstone Capital and has received gifts from The British Trust for

The Myelin Foundation, the MLD Foundation (USA) and the Athena’s Hope

Foundation.
