Adimab, Arsanis, and Platform Cloning -- a New Biotech Model?

Adimab, the yeast-based antibody discovery company that has amassed a strong portfolio of partnerships and skyrocketed to a north-of-$500m valuation, has always said it had no plans to do its own development work. If only the company could clone itself, perhaps it could venture down the development path without getting distracted from its discovery platform opportunity -- and the high multiples that can be extracted from a company that doesn't need a ton of development financing.

Enter the clone, Arsanis.

Arsanis is a biotech essentially seeded with Adimab's technology platform that will apply this yeast-based antibody discovery engine to developing drugs against infectious disease targets. The company will run research out of Vienna, Austria and plans to hire 20-25 employees in the next few months, according to founder and chief scientist Eszter Nagy, MD, PhD.

Adimab doesn't own Arsanis (though it stands to make money if Arsanis succeeds), but Adimab's investors do. The new company has raised about $10 million from SV Life Sciences, Orbimed, and Polaris, three Adimab backers. We've spoken to all those firms, to Adimab, and to Arsanis' Nagy, who hails most recently from Intercell. We'll have more on Adimab's strategy, the new company and the advantages of the model for its venture backers in a forthcoming issue of START-UP.

For now suffice it to say that Adimab has enabled a newco with its technology, helped put together a familiar syndicate to back it, and those investors can now put more money to work behind that Adimab platform. If Arsanis is successful we bet you'll see additional Adimab clones in other therapeutic spaces where Adimab's brand of faster/cheaper/better antibody discovery can yield "an unfair advantage," as one of Adimab/Arsanis' venture backers puts it.

How the company defines success remains to be seen. The $10 million should see the company all the way through to "compelling preclinical proof of concept" for a couple of antibody programs against unmet needs in infectious diseases, the players tell us, all within the next two years.

Nobody involved with Arsanis has suggested this strategy is new to biotech, but we haven't seen it work exactly like this before -- perhaps the closest comparator are the twin antibody firms Medarex and Genmab.

Meanwhile, Tillman Gerngross and Errik Anderson, Adimab's CEO and COO (founders and board members at Arsanis), have with their team transformed Adimab from a C-corp to an LLC, something we reported in December, and plan to expand the company's slate of discovery collaborations. The LLC transformation -- no easy feat according to all involved -- allows the biotech to return money from forthcoming collaborations to shareholders in a tax-efficient way.

It also dispels the notion, Gerngross says, that Adimab is for sale. "We're completely uninterested in short-term liquidity. We don't want what has happened in the past, where the company gets bought and then has a limited impact," he says. "We have a greater ambition."

DotW: Hard Truths

The feverish networking associated with BIO is but a distant memory this week as biopharma’s deal makers got back to work forging alliances or acquisitions that will provide the necessary substrate for future growth.

That this growth won’t come easily is a given. And the week’s news flow only reinforced the notion, illustrating hard truths about the commercial and regulatory complexities at work in the biopharma industry.

Who among us got bitten by reality? For starters, Takeda’s decision to cut nearly 1600 jobs illustrates the problem many Japanese pharma will be facing as their primary care drugs go generic in the coming years. Investors meanwhile pummelled NicOx, after an FDA advisory committee gave its osteoarthritis medicine naproxinod a thumb’s down. The company is pushing ahead as it awaits an official regulatory decision (the drug’s PDUFA date is July 24). Still it’s hard to believe a partner for the medicine will come anytime soon.

And Merck's quietly announced decision to call off development of MK-2578, its follow-on to Amgen’s erythropoietin stimulating agent Aranesp, showcases how difficult it can be to predict the potential market of a biosimilar. The ESA market has been under considerable pressure for some time as regulators have raised safety concerns about the products, first in the oncology setting, and now more recently in end stage renal disease. (See the May issue of The RPM Report for a Q&A with FDA’s Center for Drug Evaluation and Research Bob Temple for more on the subject.)

It’s a sure bet use of ESAs will go down, not only because of the emerging cardiovascular risks, but also because of the shift toward capitated care in end-stage renal disease that kicks in early next year. Under the new bundling guidelines, there’s pressure on physicians to use ESAs more judiciously, bolstering patients’ anemia via other mechanisms including intravenous iron use. With the commercial viability of ESAs a question, Merck must have run the numbers and determined the amount it would recoup from an Aranesp follow-on (which is expected to be priced at a slight discount to the innovator ESAs but still expensive) didn’t justify the expensive clinical trials it would have to conduct to demonstrate the medicine’s safety.

That big pharmas are wising up to such commercial hurdles ever earlier is a good thing; better to kill a product before you’ve sunk hundreds of millions of dollars into the expensive Phase III. That’s probably cold comfort to the Merck Bioventures group, which has ambitious launch goals for a spate of follow-on products by 2015.

As you contemplate other hard truths (a widening oil spill, the Greek debt crisis, the odds of Great Britain’s coalition government succeeding, the Cavs loss to that Boston team), take a brief respite into transactions land. (Reality may still bite the hand that feeds, but DotW is on its best behavior--for once.) It’s time for another edition of…

Genentech/Evotec: Evotec signed a broad multi-year discovery deal this week with Genentech to identify novel small molecule therapeutics. Further important details, including the financials as well as the therapeutic focus of the alliance, were lacking. Given Genentech’s focus on oncology, and increasingly Alzheimer’s disease and other CNS diseases, presumably Evotec’s technology will be used to develop small molecules in these arenas. Despite the dearth of specifics, the alliance is worth noting for a couple of reasons. First, Evotec’s business model seems to run counter to the collective belief that a biotech’s value is driven not by its technology but from the products derived from its platform. Indeed, as Evotec’s recent deals suggest—in addition to Genentech its signed discovery alliances with Vifor Pharma, Cubist Pharmaceuticals, Active Biotech, and Biogen Idec—management is clearly betting there is more near-term value to be gained from discovering drugs for other companies than in investing in its own pipeline. Second, how the deal proceeds will provide a window into dealmaking at Genentech, which only recently brought on a new head of business development, James Sabry, and continues to forge alliances independent of its Swiss parent. It’s interesting to note that Roche proper is well known to Evotec. The two companies have been collaborating in CNS since 2006, and Evotec is now conducting Phase II trials of EVT101 for treatment resistant depression, with Roche picking up the development costs.—Ellen Foster Licking

Abbott/Zydus Cadila: Abbott’s deal this week with India’s Zydus Cadila is a gift of DotW’s favoring buzz words, including branded generics, established products (a more diplomatic term for generic products), and emerging markets. The news is proof yet again that many big pharmas are following the lead of Sanofi-Aventis and GlaxoSmithKline, which have been the most aggressive in building a commercial presence in “pharmergent” economies such as Brazil, Russia, India and China via branded generics. As part of the recently announced alliance, Abbott will sell 24 Zydus drugs for pain, cancer, cardiovascular disease, respiratory ailments and neurological disorders in 15 emerging markets. Many, though not all, of the licensed drugs will be in complementary therapeutic areas to Abbott's existing branded generics portfolio, which came to the diversified health care giant via its Solvay and Knoll acquisitions. Specific financial terms of the deal were not disclosed, but should the collaboration be a success, Abbott has the option to license more than 40 additional products. In conjunction with the deal, Abbott also announced the creation of a stand-alone established products division with $5 billion in current pharmaceutical sales. The business unit will be led by Michael Warmuth, the former head of Abbott’s diagnostics division. Two years ago, Pfizer set up a similar stand-alone unit as a strategy to cope with flagging US drug sales, especially come 2011 when its cholesterol-lowering medicine Lipitor goes off patent. And that group was also a force at the dealmaking table this week, strengthening its ongoing collaboration with India-based Strides Arcolab (announced earlier this year) via the signing of two licensing and supply agreements. In part one, Strides has agreed to license and supply 38 generic oncology meds to Pfizer in various markets, including the EU, Canada, and Australia. Part two gives Pfizer access to niche sterile injectables for the US market.—Jessica Merrill and EFL

Pfizer/Ergonex: It’s not all about extending the life cycle of established products at Pfizer these days. This week the biggest big pharma’s specialty care business unit inked a deal with Ergonex Pharma for the biotech’s Phase II product terguride, which is in development as a treatment for pulmonary arterial hypertension (PAH). The agreement gives Pfizer world-wide rights (excluding Japan) to the product; in exchange Pfizer will support the ongoing mid-stage clinical trial, taking full control of the compound at the study’s completion. While Pfizer isn’t sharing specific financial details, it will pay Ergonex undisclosed milestones and sales royalties. Terguride, which has an orphan drug designation in the US and the EU, is an oral antagonist antagonist of the 5-HT2B and 5-HT2A serotonin receptors, shutting down signals triggering fibrosis and the narrowing of pulmonary arterial walls that over time results in PAH. The medicine is already approved in Japan for the treatment of hyperprolactinemia.—EFL

Genzyme/Tianjin International Joint Academy of Biotechnology and Medicine (TJAB): Another week, another biopharma looks to ink a discovery deal in China. This week it’s Genzyme’s turn to trumpet a strategic partnership with TJAB, which has an impressive list of co-founders, including China’s Ministry of Science and Technology, its Ministry of Commerce, its Ministry of Health, and the State Food and Drug Administration (China’s equivalent of the US FDA). The partnership was apparently celebrated with the requisite pomp and circumstance, including an official signing ceremony attended by top Chinese officials and senior R&D types from Genzyme. This isn’t the first time Genzyme has traveled east to ink a collaboration. Back in 2007 the biotech signed a deal with Sunway Biotech to develop and commercialize Genzyme’s most advanced gene therapy candidate, Ad2/HIF-1a, which is being tested as a treatment for various forms of peripheral arterial disease. The big biotech is also in the process of building a $100 million R&D center in Beijing, with construction scheduled for completion in 2011. In a small way, the agreement offers the beleaguered Cambridge-based Genzyme an opportunity to shift the news cycle away from the forthcoming annual shareholder meeting and Termeer’s ability to withstand pressures from activist shareholder Carl Icahn who is pushing for his removal.--EFL
