Adimab is taking an uncommon approach to exploiting the value of its antibody-discovery technology. The Lebanon, NH-based biotech startup has no plans to ever develop its own drugs—CEO Tillman Gerngross says he thinks Adimab can become successful with income from drug-discovery and licensing deals alone.
That is the level of confidence that Gerngross apparently has in Adimab’s proprietary method for significantly streamlining and expediting how antibody drugs are discovered. Investors Polaris Venture Partners, SV Life Sciences, Borealis Ventures, and OrbiMed Advisors have bet millions that the confidence is well-founded. Adimab closed its third round of financing late last year, but it hasn’t disclosed the amount. When I visited the company this week, Gerngross told me that sometime around the end of March he expects to disclose a list of discovery deals his firm has landed.
A lot of attention is paid to how antibody drugs are discovered, as such medications generate tens of billions of dollars in annual sales. South San Francisco-based Genentech (NASDAQ:DNA), for one, reported revenue of about $4.5 billion in 2007 on U.S. sales of its top two antibody drugs, the cancer treatment bevacizumab (Avastin) and rituximab (Rituxan), which is approved for treating lymphoma and rheumatoid arthritis. However, companies in pursuit of new antibody drugs must often pay millions of dollars to multiple firms—such as Cambridge, MA-based biotech firm Dyax (NASDAQ:DYAX)—to license antibody-discovery technologies.
Adimab wants to provide one-stop shopping for these firms. The startup has a yeast-based discovery technology that mimics the human immune system and doesn’t require the use of mice or Dyax’s widely used “phage display” method to identify antibodies with the potential to treat diseases.
Gerngross says the firm’s synthetic immune system consists of yeast cells that are genetically engineered to produce some 10 billion different human antibodies. Those antibodies are attached to the surface of the cells that produce them. Next, the firm adds a potential drug target—a protein from breast cancer cells, say—that has been tagged with florescent dye. The antibodies that bind to those tagged target proteins are then identified as potential treatments for the cancer. The yeast cells that made those particular antibodies are then collected to make more of the antibodies for further testing.
