Antisense drug designed to reduce tau protein in the CNS
Ionis earns $10 million milestone payment from Biogen
CARLSBAD, CA, USA I October 13, 2017 I Ionis Pharmaceuticals, Inc. (NASDAQ: IONS) today announced that it has initiated a Phase 1/2a clinical study of IONIS-MAPTRx in patients with mild Alzheimer’s disease (AD). Ionis earned a $10 million milestone payment from Biogen related to the initiation of this study.
IONIS-MAPTRx is an antisense drug designed to selectively reduce the production of microtubule-associated protein tau (MAPT), or tau protein, in the brain. Tau misfolding leads to the accumulation of neurofibrillary tangles inside brain cells. These tangles are a hallmark feature of a spectrum of neurodegenerative diseases known as tauopathies, which include AD and some forms of frontotemporal dementia (FTD). AD is the most common form of dementia, accounting for an estimated 70% of cases. FTD is a rare form of early-onset dementia resulting from neuronal damage in the frontal and temporal lobes of the brain.
“In contrast to amyloid plaques that may begin to deposit in the brain for up to 20 years before the onset of AD, tau deposits are spatially and temporally associated with the brain regions where atrophy occurs and neurocognitive deficits originate. IONIS-MAPTRx is designed to reduce the production of all of the many forms of tau in all regions of the brain,” said C. Frank Bennett, Ph.D., senior vice president of research at Ionis Pharmaceuticals.
The three-month randomized, placebo-controlled, dose escalation Phase 1/2a clinical study will evaluate the safety and activity of IONIS-MAPTRx in approximately 44 patients with mild AD. In the study, IONIS-MAPTRx is administered as a once-monthly intrathecal injection directly into the cerebral spinal fluid, similar to the way SPINRAZA® (nusinersen) is administered. Biogen has an option to develop and commercialize IONIS-MAPTRx.
“IONIS-MAPTRx is another exciting program within our strategic collaboration with Biogen,” said B. Lynne Parshall, chief operating officer of Ionis Pharmaceuticals. “Targeting MAPT represents a unique opportunity to address the unmet need in both rare and more prevalent tauopathies. The first clinical study with IONIS-MAPTRx is in patients with AD, however, in parallel, we also plan to develop IONIS-MAPTRx for patients with FTD, a rare disease population. This strategy has the potential to accelerate the drug’s path to market.”
ABOUT IONIS AND BIOGEN
Ionis and Biogen have a broad strategic collaboration combining Biogen’s expertise in neurology with Ionis’ leadership in antisense technology to develop novel therapies to treat neurological disorders. SPINRAZA, an antisense drug developed with Ionis Pharmaceuticals’ proprietary antisense technology is the first commercial drug from this collaboration. SPINRAZA is approved in global markets for the treatment of patients with spinal muscular atrophy (SMA). Biogen is responsible for commercialization of SPINRAZA. Also under this collaboration, Ionis and Biogen are developing IONIS-SOD1Rx for amyotrophic lateral sclerosis (ALS), and IONIS-BIIB5Rx, IONIS-BIIB6Rx, and IONIS-BIIB7Rx to treat undisclosed neurodegenerative diseases.
ABOUT IONIS PHARMACEUTICALS, INC.
Ionis is the leading company in RNA-targeted drug discovery and development focused on developing drugs for patients who have the highest unmet medical needs, such as those patients with severe and rare diseases. Using its proprietary antisense technology, Ionis has created a large pipeline of first-in-class or best-in-class drugs, with over three dozen drugs in development. SPINRAZA® (nusinersen) has been approved in global markets for the treatment of spinal muscular atrophy (SMA). Biogen is responsible for commercializing SPINRAZA. Drugs that have successfully completed Phase 3 studies include inotersen, an antisense drug Ionis is developing to treat patients with TTR amyloidosis, and volanesorsen, an antisense drug discovered by Ionis and co-developed by Ionis and Akcea Therapeutics to treat patients with either familial chylomicronemia syndrome or familial partial lipodystrophy. Akcea, an affiliate of Ionis, is a biopharmaceutical company focused on developing and commercializing drugs to treat patients with serious cardiometabolic diseases caused by lipid disorders. If approved, volanesorsen will be commercialized through Ionis’ affiliate, Akcea. Volanesorsen filings for marketing approval have been submitted in the U.S., EU and Canada. Inotersen is progressing toward regulatory filings for marketing authorization. Ionis’ patents provide strong and extensive protection for its drugs and technology.
