Biogen to acquire first-in-class Phase IIb ready asset for cognitive impairment

PF-04958242 is an AMPA receptor potentiator designed to facilitate neurotransmission.

Biogen has agreed to acquire from Pfizer a first-in-class, Phase IIb ready AMPA receptor potentiator for cognitive impairment associated with schizophrenia (CIAS). The purchase will include an upfront payment of $75 million with up to $515 million in additional development and commercialization milestone payments, as well as tiered royalties in the low to mid-teen percentages.

AMPA receptors mediate fast excitatory synaptic transmission in the central nervous system, a process which can be disrupted in a number of neurological and psychiatric diseases, including schizophrenia.

PF-04958242 has previously demonstrated an acceptable safety profile and treatment effect trends across multiple domains of cognition in Phase 1b clinical studies. Biogen aims to initiate a Phase IIb trial in the second half of 2018.

“As pioneers in neuroscience, Biogen continues to explore new ways to treat serious diseases where there are few or no options, such as CIAS,” stated Michel Vounatsos, Biogen CEO. “Given the significant unmet patient need and Biogen’s ability to apply its scientific expertise in this area, we are enthusiastic to advance development of this asset as we continue to expand our neuroscience pipeline, including in our emerging growth areas such as neuropsychiatry.”

Worldwide there are greater than 20 million people living with schizophrenia and it is estimated that the majority of them live with some degree of cognitive impairment attributable to the disease. Cognitive impairment is increasingly recognized as one of the greatest unmet needs in the effective treatment of schizophrenia.

“When cognition is impaired, you lose the ability to make sense of the world. Things we often take for granted in our daily lives, including processing information, planning and remembering, all become difficult or impossible,” said Michael Ehlers, executive vice president, Research & Development at Biogen. “Cognition can be impaired in multiple neurological and neuropsychiatric diseases, including schizophrenia. And we know that the extent of cognitive deficits in patients with schizophrenia is a strong predictor of daily functioning. We look forward to quickly pursuing development of this potential innovative therapy to treat such a devastating disease.”

Biogen expects the deal to close in the second quarter of 2018.
