Anaphore Snags $110M Deal With Mitsubishi Tanabe to Make Drugs for Immune Disorders

Anaphore has found a new corporate benefactor to help create a new generation of more effective biotech drugs.

The San Diego-based biotech company is announcing today it has formed a partnership with Osaka, Japan-based Mitsubishi Tanabe Pharma to develop new protein drugs for autoimmune disorders. Anaphore will get $5 million in upfront cash, plus research support, another $110 million in potential milestone payments, and royalties on sales if one of the Anaphore drug programs goes on to become marketed product. Similar terms could kick in for Anaphore if Tanabe picks two more of Anaphore programs. The money will provide access to Anaphore’s technology, which creates specific protein molecules which are supposed to bind more thoroughly with targets on cells than traditional antibodies.

This is the first publicly announced partnership for Anaphore, although the company does have one other undisclosed collaboration with a biotech company, CEO Kathy Bowdish says. The Tanabe deal is an important validating step for the startup, which was founded in December 2007 and has since raised a total of $38 million in venture capital from 5AM Ventures, Versant Ventures, Apposite Capital, GlaxoSmithKline’s SR One venture group, Merck Serono, and Aravis Venture Associates. The investors’ bet is that Anaphore can create genetically engineered protein drugs with greater capability to bind with targets than today’s antibodies, which are lean and mean enough to penetrate inside bulky tissues, and which are equally good at blocking a biological pathway, or activating it.

“This has been an exciting opportunity, in which I’m trying to take everything I had learned over 10 years with antibodies, and thinking about how to improve on that,” says Bowdish. “We truly view this partnership as very validating.”

Quite a few companies have been sprouting up and raising cash in the last couple years with similar notions of developing “bio-superiors” or “bio-betters.” Cambridge, MA-based Eleven Biotherapeutics, Seattle-based Allozyne, San Diego-based Ambrx, and South San Francisco-based Sutro Biopharma are all examples could be filed under that header.

Anaphore’s work is still at a very early stage, and it isn’t saying much publicly about its strategy. The company has tested its protein drug candidates in the lab dish, and has seen evidence of activity there against important targets that appear on cancer and inflammatory disease cells, Bowdish says. Mitsubishi Tanabe and Anaphore aren’t disclosing which target for autoimmune disease they are pursuing first, and Bowdish didn’t say when she hopes to move that program ahead into clinical trials. She did say that part of Anaphore’s work concentrates on making “bi-specific” protein drugs, which are specifically engineered to bind with not just one target of interest, but two distinct targets simultaneously.

Since we haven’t covered Anaphore in depth before, I asked Bowdish to explain a little bit of the background. She has a long history in San Diego biotech as the co-founder, CEO and chief scientist at Prolifaron, an antibody drug spinoff from The Scripps Research Institute that was acquired by New Haven, CT-based Alexion Pharmaceuticals (NASDAQ: [[ticker:ALXN]]).
