Deals of the Week's Dead Presidents Edition

As many Americans prepare for their three-day weekend celebrating the birthdays of two great Presidents, Deals of the Week cynically notes that a lot of Americans don’t really love their Presidents until after they’re dead – specifically, the ones whose visages have been enshrined on legal tender. Little Walter sang an amusing blues number about a nation’s love for currency and the commanders-in-chief who adorn it, conveniently glossing over the presence of several non-Presidents, including Alexander Hamilton and Benjamin Franklin, on commonly circulated bills.

It takes far more than even a rarely-seen Salmon P. Chase to get a pharma deal done, but sometimes it also takes more than mere dollars – or euros, pounds, or whatever you like – to keep everyone satisfied. Witness Sanofi-Aventis SA’s bid for Genzyme Corp., a once-hostile overture sweetened with contingent value rights, or CVRs – in this case, options for further payments based on regulatory and manufacturing milestones on Genzyme drugs – that could account for nearly a sixth of the deal’s value. The CVRs primarily relate to pipeline considerations, and a new study shows just how crucial they are to Sanofi and its peers.

According to a report issued Thursday by Bernstein Research’s Tim Anderson, Sanofi’s pipeline was expected to contribute less than 3% of its overall revenues by 2015, the smallest share among nine Big Pharmas studied – at least, prior to the Genzyme deal, which includes a potential blockbuster in multiple sclerosis. Bristol-Myers Squibb, by contrast, can expect nearly 18% to come from its pipeline by 2015, thanks to R&D spending approaching $4 billion annually in the coming years as well as a relatively small revenue base, according to Bernstein’s report. Meanwhile, Eli Lilly & Co. is expected to be among the biggest R&D spenders relative to revenue, though it can expect the fewest returns in total Benjamins from drugs currently in its pipeline, and only a middle-of-the-pack performance as a percentage of overall 2015 sales.

Where do exciting pipeline drugs come from when they're not homegrown? Why of course, it's...


Sanofi/Genzyme: Preliminary conversations between Sanofi and Genzyme last summer gave way to a publicly announced bid to shareholders in August, then a hostile overture in October, protracted negotiations in the following months, and finally a deal in February. The French pharma will pay $74 per share for Cambridge, Mass.-based Genzyme, along with CVRs entitling each shareholder to payouts based on drug development milestones for pipeline drug Lemtrada (alemtuzumab) for multiple sclerosis and production volumes for approved orphan drugs Cerezyme (imiglucerase) and Fabrazyme (agalsidase). While the $74 per share bid exceeded Sanofi’s rejected bid by $5, the CVRs are thought to have been the key to completing the deal, potentially adding $14 per share – $13 from Lemtrada milestones – to its value. Sanofi, whose massive diabetes franchise is balanced by diverse offerings including vaccines and soon-to-be-off-patent anticoagulant Lovenox (enoxaparin), gets Genzyme’s expertise in rare diseases, as well as its manufacturing capabilities. Though some believe it may have overpaid, the aggressive milestone timeline will bear out the deal’s true value – suggesting that the real work, including a potentially tricky integration process, is yet to be done. – P.B.

Astellas/AVEO: In one of the richest oncology deals in the past few years, Japan’s second-largest pharma placed a big bet on AVEO Pharmaceuticals Inc.’s most advanced compound, the Phase III drug tivozanib. Astellas Pharma Inc. paid $125 million up front, while committing to a milestone schedule that could add more than $1.3 billion to the deal, to license tivozanib worldwide, save for Asian territories already licensed to Kyowa Hakko Kirin under an existing agreement. The deal includes $575 million for clinical and regulatory milestones and $780 million in commercial payments, and covers all indications of the drug, currently farthest along in studies for renal cell carcinoma. The two companies will split profits 50/50 in North America and Europe, where they will also share development costs and sales forces, although Astellas is expected to lead commercialization in Europe while AVEO does so domestically. Phase III results are due in mid-2011 for tivozanib, a blocker of vascular endothelial growth factor (VEGF), although an NDA isn’t expected until 2012, pending a favorable clinical outcome. The agreement extends Astellas’ ongoing commitment to oncology beyond its $4 billion acquisition of OSI Pharmaceuticals last year. – P.B.

AdventRx/SynthRx - About two years ago, AdventRx Pharmaceuticals had placed its lead clinical programs on hold and cut staff twice, to a headcount of five. Now, the San Diego-based firm has an FDA action date for its lead program, chemotherapy drug Exelbine (vinorelbine injectable emulsion), and is acquiring privately held SynthRx in an all-stock deal to move into the sickle cell disease (SCD) space. AdventRx, focused on a growth-by-acquisition strategy, will acquire Texas-based SynthRx through an equity deal in which more than 75% of merger consideration is based on NDA acceptance and approval of SynthRx’s lead program and more than 95% is based on milestone achievement. In exchange for an upfront consideration giving SynthRx’s shareholders a 4% interest in AdventRx, SynthRx becomes a wholly owned subsidiary of AdventRx, giving the latter firm ownership of the Phase III poloxamer 188 program. Initially advanced into Phase III in myocardial infarction by CytRx, 188 is a purified form of a rheologic and antithrombotic agent to be studied first in pediatric SCD and thought to have potential in other illnesses involving microvascular flow abnormalities, such as heart attack, stroke and hemorrhagic shock. During an investor call Feb. 14, CEO Brian Culley explained that if every milestone in the deal is paid out fully, SynthRx shareholders would end up with a 40% stake in AdventRx. “If the NDA is accepted and approved, [that is] something I think we would be happy to make these equity payments for,” he added. – Joseph Haas

Bayer/Philogen: The crumbling of one European deal led to the cancellation of a potential bellwether IPO. Swiss-Italian biotech Philogen SpA might be searching for an aspirin after its oncology deal with Bayer AG came apart, prompting Philogen to cancel its anticipated IPO. Bayer abruptly walked away from its licensing arrangement for Philogen’s L19 therapies, vascular-targeting immunocytokine drugs that are being investigated for several different cancers. The two companies’ association dates to 1999, when Schering AG took an option on Philogen’s research into antibodies that inhibit angiogenesis, leading to a formal worldwide license in 2003. Despite the extended relationship, Bayer gave no specific reason for unraveling the deal. Philogen, which says it has six clinical antibodies targeting cancer as well as a rheumatoid arthritis drug and a preclinical ophthalmology program for age-related macular degeneration, was expected to list on the Milan exchange February 18, but instead scuttled what was expected to be Europe’s first IPO of 2011. In the offering, thought to be a signal of a warming climate for biotech listings, Philogen had anticipated raising as much as €65.3 million ($89.3 million) by floating 23% of its shares. The failed listing is Philogen’s second IPO cancellation; it withdrew a planned offering in 2008 as well, citing unfavorable market conditions. – P.B.
