Alexion, AstraZeneca’s Rare Disease group, has entered into an exclusive global collaboration and licence agreement with Neurimmune AG for NI006, an investigational human monoclonal antibody currently in Phase Ib development for the treatment of transthyretin amyloid cardiomyopathy (ATTR-CM). NI006 specifically targets misfolded transthyretin and is designed to directly address the pathology of ATTR-CM by enabling removal of amyloid fibril deposits in the heart, with the potential to treat patients with advanced ATTR-CM.
Under the agreement, Alexion will be granted an exclusive worldwide licence to develop, manufacture and commercialise NI006.
ATTR-CM is a systemic, progressive and fatal condition that leads to progressive heart failure and high rate of fatality within four years from diagnosis.1 It remains underdiagnosed and its prevalence is thought to be underestimated due to a lack of disease awareness and the heterogeneity of symptoms.2
Marc Dunoyer, Chief Executive Officer, Alexion, said: “With 30 years of experience in developing medicines for people with rare diseases, Alexion is uniquely positioned to advance innovative science for small patient populations who are frequently underdiagnosed. We look forward to applying this expertise to the development of NI006, which is designed to clear cardiac amyloid fibril deposits with the potential to improve cardiac function for patients living with advanced ATTR-CM, who are currently underserved by existing treatment options.”
There is a significant unmet medical need for patients with various types and levels of severity of amyloidosis that may require multiple mechanisms of action to address those needs. NI006, an ATTR depleter, adds a novel and complementary approach to AstraZeneca and Alexion’s pipeline of investigational therapies focused on amyloidosis and strengthens our broader commitment to addressing cardiomyopathies that can lead to heart failure.
Alexion will pay Neurimmune an upfront payment of $30m with the potential for additional contingent milestone payments of up to $730m upon achievement of certain development, regulatory and commercial milestones, as well as low-to-mid teen royalties on net sales of any approved medicine resulting from the collaboration.
Neurimmune will continue to be responsible for completion of the current Phase Ib clinical trial on behalf of Alexion, and Alexion will pay certain trial costs. Alexion will be responsible for further clinical development, manufacturing and commercialisation.
The transaction is expected to close following satisfaction of customary closing conditions and regulatory clearances.
