Arrowhead Acquires Novartis’ RNAi Research and Development Portfolio

– Conference Call Today at 8:30 a.m. EST

PASADENA, Calif.–(BUSINESS WIRE)–

Arrowhead Research Corporation (NASDAQ: ARWR), a biopharmaceutical

company developing targeted RNAi therapeutics, today announced the

acquisition of Novartis’ entire RNAi research and development portfolio

and associated assets. The acquisition includes assignment of certain

patents and patent applications owned or controlled by Novartis related

to RNAi therapeutics, an exclusive license in the RNAi field to other

patents and patent applications owned or controlled by Novartis,

assignment of a third party license, three pre-clinical RNAi candidates,

and other related assets. The company is hosting a conference call at

8:30 a.m. EST to discuss the acquisition.

Key aspects of the acquisition include the following:

  • Multiple patent families covering RNAi-trigger design rules and

    modifications that fall outside of key patents controlled by

    competitors, which the Company believes provides freedom to operate

    for any target and indication;

  • Novel intracellular targeting ligands that enhance the activity of

    RNAi-triggers by targeting the RNA-induced silencing complex (RISC)

    more effectively and improving stability once RISC is loaded;

  • An assignment of Novartis’ license from Alnylam Pharmaceuticals

    granting Arrowhead access to Alnylam intellectual property, excluding

    delivery, for 30 gene targets chosen by Novartis;

  • A pipeline of three candidates initiated by Novartis and for which

    Novartis has developed varying amounts of preclinical data.

“This is an important deal for us. Novartis has been working in the RNAi

field for over a decade and their developments in proprietary

oligonucleotide formatting and modifications are some of the best we’ve

seen. We anticipate this acquisition will provide us with substantially

expanded freedom to operate, proprietary technology that appears to

enhance the activity of RNAi triggers, access to non-delivery Alnylam

RNAi IP for 30 targets, and three programs that went through the

rigorous Novartis vetting process,” said Christopher Anzalone, Ph.D.,

president and chief executive officer of Arrowhead. “We now have

additional flexibility to optimize each new candidate using the most

effective RNAi-trigger design and modifications. We look forward to

incorporating these novel technologies into future drug candidates.”

Under the terms of the agreement, Arrowhead previously made a payment to

Novartis of $7 million in cash and will provide an additional payment of

$3 million in cash and $25 million in Arrowhead common stock within 30

days. Novartis is also eligible to receive milestones and single digit

royalties on sales of future products in connection with the agreement.
