Anavex Life Sciences Corp. is a biopharmaceutical company engaged in the discovery and development of new drugs for the treatment of central nervous system (CNS) diseases and different types of cancer, utilizing its proprietary SIGMACEPTOR Discovery Platform.
The Anavex portfolio involves sigma receptor ligand compounds in the preclinical stage that target neurodegenerative diseases and cancer. According to a number of recent studies, these ligands have the ability to target certain CNS conditions, such as depression and Alzheimer’s disease, as well as certain types of cancer, through agonism or antagonism of sigma receptors
Anavex’s neuroscience program targets compounds that protect and enhance the function of the CNS in order to treat conditions such as Alzheimer’s disease, epilepsy, depression and neuropathic pain. The company’s oncology program targets compounds that selectively kill malignant cells to treat three types of cancer which are prostate, melanoma, and pancreatic cancer.
Anavex boasts a network of strategic collaborations with FORENAP Pharma EURL, an international Contract Research Organization (CRO), and leading academic institutions, such as Université Montpellier, University of Strasbourg, University of Nice Sophia Antipolis.
The company’s drug development program is based around its proprietary SIGMACEPTOR Discovery Platform, which generates small-molecule candidates. The company currently has seven product candidates in development for eight disease indications.
ANAVEX 2-73 is the company’s lead drug candidate to treat Alzheimer’s disease and ANAVEX 19-144 is the lead drug candidate to treat epilepsy. During pre-clinical trials (in-vitro and in-vivo in mice), these compounds demonstrated significant neuroprotective, anti-amnesic and anti-convulsive properties. It also exhibited an excellent safety profile and therapeutic activity at very low doses.
ANAVEX 2-73 has been shown to provide protection from oxidative stress, which damages and destroys neurons and is believed to be a primary cause of Alzheimer’s disease. Research in recent years indicates that oxidative stress is a precursor to amyloid-beta plaques and tau (see also Neuro-Fibrillary Tangles), and could be a novel and appropriate therapeutic target.
In epilepsy, ANAVEX 19-144 has shown to control seizures and the epileptogenesis process. The neuroprotective properties prevent the process that causes long-term damage to tissue and cells as well as biochemical and physiological alterations to the brain from epileptic seizures.
The company's ANAVEX 1-41 drug candidate is a compound in pre-clinical development for Alzheimer’s disease and depression. Animal studies indicate that ANAVEX 1-41 prevents the expression of caspase-3, an enzyme that plays a key role in programmed cell death and in the loss of cells in the hippocampus, the part of the brain that regulates learning, emotion and memory.
ANAVEX 2-73 is scheduled to enter Phase 1 Human Clinical Trials in 2010.
Anavex’s SIGMACEPTOR-C program involves the development of novel drug candidates targeting cancer. These compounds induced apoptosis during in-vitro and in-vivo studies in three types of cancers which are prostate, melanoma, and pancreas, demonstrating evidence of pro-apoptotic and anti-metastatic action with low toxicity.
In advanced pre-clinical studies, ANAVEX 1007, the company’s lead drug candidate for the treatment of prostate cancer, revealed anti-tumor potential without major toxic side effects. The compound has also been shown to selectively kill human cancer cells without affecting normal/healthy cells and also to suppress tumor growth in immune-deficient mouse models.
ANAVEX 1007 is scheduled to enter Phase 1 Human Clinical Trials in 2010.
