Deals Of The Week Gets Exclusive

Commitment is such a weighty decision, isn’t it? Whether it’s high schoolers obsessed about going steady or 30-somethings who stay over three nights a week but refuse to stash their extra underwear in an available drawer, making the choice to be exclusive is hard. What if things don’t work out? Gulp.

In biopharma land, exclusivity is no less thorny a subject, especially when it relates to options-to-acquire. This week news comes that Novartis, which alongside Cephalon remains one of the most active in inking this specific flavor of option-based deals, is at it again. On November 11, Novartis said it had taken an option either to buy San Diego-based Aires Pharmaceuticals outright or license the biotech’s mid-stage treatment for pulmonary arterial hypertension called Aironite.

Along with the option announcement, Aires said it reeled in a $20 million Series B financing, enough money to finish Phase II trials of Aironite, a nitric oxide prodrug that causes vasodilation and has anti-inflammatory properties. Novartis didn’t officially take part in the financing, but it has ties nonetheless. That’s because the new investor, MPM Capital, made the investment out of its MPM Bio IV NVS Strategic Fund (try saying that three times fast), a side-car fund backed by—you guessed it—Novartis. Existing Aires backer ProQuest Investments also participated in the round.

Details surrounding the option are murky. We know that Novartis paid a separate fee for the right to acquire Aires after it successfully completes Phase II studies of Aironite and, all-in, the deal price could reach $250 million. But the price of the option remains undisclosed, as do values for the initial acquisition payment and the regulatory and sales milestones.

Since its formation in 2007, the MPM/Novartis fund has signed at least eight option deals, including the recent Aires transaction, according to Elsevier’s Strategic Transactions. The Aires deal hews closely to a familiar formula designed to give Novartis an advantage at the deal-making table. Except for the overall buy-out price, the Aires news is reminiscent of Novartis’ March 2009 option-to-acquire Proteon Therapeutics for up to $550 million. That deal, contingent on Proteon’s ability to demonstrate proof-of-concept with its Phase I/ II recombinant human elastase, was also announced concurrently with the first tranche of Proteon's $50 million Series B financing.

Given the cash constraints privately-held start-ups face, option-type deal making has become more common. Such deals might cap investor upside, but the additional non-dilutive cash and greater certainty of an exit mean it’s an offer investors have a hard time refusing.

But as anyone who's watched a Mafia flick can tell you, "hard to refuse" isn't the same as "popular." Some VCs and biotech executives worry that the Novartises of the world will try and wiggle out of the pre-agreed upon terms that trigger an alliance or acquisition. Indeed, there is recent precedent.

In 2007, Radius optioned its mid-stage osteoporosis medicine, BA058, to Novartis for $10 million. According to the terms of the deal, once Radius announces Phase II data for BA058, the big pharma has 90 days to evaluate the information before making a go/no-go decision. At the end of the option period, Novartis can say “no” and walk away, leaving Radius to shop the product to anyone they want, or “yes” and trigger the pre-negotiated deal. The thing is, Radius announced its Phase II data in August 2009, and there’s been no nay or yeah about the option in the intervening period. Math may not be this blogger’s strongest suit, but even a nine-year old can calculate that a decision from Novartis is a year overdue.

Indeed, there’s little clarity on whether any of the options associated with the MPM/Novartis fund have actually been exercised, even though a number of them have undoubtedly reached critical decision points. Does Novartis’ decision regarding BA058say anything about the long-term viability of the option model?

Maybe yes. Maybe no. (Depending on the daisy--er, asset-- it's a little bit like playing effeuiller la marguerite.)Given current uncertainties in the marketplace, it’s a fair bet option-style deal making isn’t going away. And for the cynics in the readership, there are happy endings: Purdue Pharma and Cephalon recently exercised prior options associated with their respective tie-ups with Infinity Pharmaceuticals and BioAssets Development Corp.

Ultimately commitment is a leap of faith—or at least a flying leap. Here at IN VIVO Blog we’ve got your exclusive line-up of deal making news. It’s time for another edition of…


Clovis Oncology/Clavis Pharma: News flash! IN VIVO Blog has learned that several other firms were also involved in this deal: Cleavis, which is working on DNA repair mechanisms; Clyvis, an under-the-radar Scottish start-up; and Clivus, with the latest advances in phrenology! Of course we jest. The real deal here is just between Clovis and Clavis, announced Nov. 11, and it expands upon the November 2009 tie-up that saw Clovis pay Clavis $15 million upfront for partial rights to CP-4126, a reformulated gemcitabine currently in Phase II for pancreatic cancer. The reformulation with Clavis's Lipid Vector Technology aims to promote gemcitabine uptake in patients with low levels of the nucleoside transporter protein hENT1, which normally allows gemcitabine into cancer cells. Several studies suggest a significant percentage of pancreatic cancer patients, perhaps up to 67%, have low levels of hENT1, and the partners are working on a companion diagnostic to sort low- from high-hENT1 patients. With the expanded deal, Clovis pays $10 million immediately for full global rights, plus $30 million in Asian milestones and up to $165 million in sales milestones. Clovis is still on the hook for the $365 million in milestones attached to the development and commercial rights it originally bought for North America, South America and Europe. -- Alex Lash

GlaxoSmithKline/Xenoport: The partners on the restless-leg syndrome (RLS) treatment Horizant said Nov. 8 they had amended their February 2007 agreement to give the San Francisco Bay Area biotech the right to pursue development of the drug for diabetic peripheral neuropathy (DPN) and additional indications in the US. All ex-US rights previously granted to GSK have reverted back to Xenoport, as well, and the firms have made undisclosed financial adjustments in milestones and royalty rates to reflect the new responsibilities. GSK remains responsible for US approval of Horizant – formerly known as Solzira and burdened with a track record of clinical and regulatory misses – for restless-legs syndrome and post-herpetic neuralgia. The drug failed a Phase II trial for DPN in 2009, then FDA rejected Horizant for RLS in February 2010, issuing a complete response letter and prompting investors to bail on Xenoport. But FDA has accepted GSK's response and has issued a new PDUFA date of April 6, 2011. Under the original deal, GSK paid Xenoport £40 million upfront, promised up to £298 million in milestones, and sales royalties. -- A.L.

Eli Lilly/Avid Radiopharmaceuticals: Lilly announced a deal this week, but not the blockbuster M&A investors have been hankering for. Even as ratings agencies downgrade the Indianapolis pharma, Lilly is sticking to its strategic guns, replenishing its pipeline with bite-sized transactions centered on late-stage assets. The company’s decision Nov. 8 to purchase Avid Radiopharmaceuticals, a privately-held diagnostics company that specializes in the detection of chronic diseases through brain imaging, is further evidence of Lilly’s mindset. It also shows that despite the risks of Alzheimer’s drug development (semagacestat, anyone?), Lilly still believes in this therapeutic arena. Lilly will pay $300 million upfront to acquire all outstanding shares of Avid and another $500 million tied to regulatory and commercial milestones to get its hands on the biotech’s molecular imaging agent, florbetapir F18, which is pending FDA approval. While such a large sum isn't unusual for a biotech with a late-stage asset in a valuable therapeutic area like oncology, it's almost unprecedented in the diagnostics arena, where M&A targets generally have marketed assets and are acquired not by drug companies but by fellow diagnostics specialists. Given the risks associated with Alzheimer's, technologies that help prevent costly late-stage failures like semagacestat are worth a premium. And Lilly, determined to push forward its remaining Phase III Alzheimer's drug, the antibody solanezumab, certainly can’t afford to repeat its semagacestat outcome. But those peculiarities mean the startling deal price for Avid is likely the exception rather than the rule. Meantime, Avid’s backers, which include Safeguard Scientifics, Alta Partners, Pfizer Strategic Investment Group, and Lilly's own corporate venture group, can celebrate a tidy exit. Based on the deal’s upfront alone, investors stand to realize an estimated 4x return on their venture, having put in just under $70 million since Avid’s 2004 founding. -- Lisa Lamotta and E.L.

Pfizer/Biovista: This week’s deal between Pfizer and Biovista illustrates yet again the thrifty mindset at work in the halls of the the biggest pharmas. To discover additional uses for existing compounds, Pfizer has inked a pilot research collaboration with privately-held Biovista that gives the big drug maker access to the service firm's proprietary datamining technology, which uncovers potential utility in various therapeutic areas, including oncology, ophthalmology, metabolic disease, and CNS disorders. Biovista will collaborate with Pfizer’s Indications Discovery Unit to identify up to three novel indications for each of the Pfizer candidates being evaluated. In return, Pfizer will pay Biovista an undisclosed upfront payment and success-based milestones. Biovista has inked numerous partnerships around its technology, including one earlier this year with the FDA to help regulators identify and understand the mechanisms resulting in adverse events. Biovista isn't content to remain a service play; in 2009, the firm started its own drug development program based on repositioned compounds in CNS diseases. Pfizer, meanwhile, continues to try to wring value from every compound in its research pipeline. This is the second repositioning deal the behemoth has inked in 2010 alone. In May, it announced it was teaming up with Washington University in a $22.5 million, five year collaboration designed to find new uses for a 500-compound Pfizer data set. -- E.L.

DOTW Examines Paraskevidekatriaphobia And Other Aspects of Numerology

DOTW isn't superstitious. Nah, it takes more than yet another freak Washington DC-area thunderstorm and a power outage on deadline day to instill paraskevidekatriaphobia in this hardy crew. Then again, we did go out of our way not to walk under any ladders or cross paths with black cats. And thank G-d the main office only has 6 floors.

More sensitive souls should take heart. After a paranoia-inducing 2009 in which there were nine Friday the 13ths, today's combination of Friday and 13 is the only one of the year. (Turns out the number depends on the vagaries of the Gregorian calendar.)

Numbers figured more prominently in the biopharma news than in the actual deals that went down. Perhaps triskaidekaphobia is the reason financials went undisclosed in roughly half of deals outlined in this week's edition.

Back to the news. For Genzyme, 4 could be the crucial number, or the years it will take to right its troubled Allston Landing plant. News that Genzyme was taking a $6.5 million charge and a loss for the second quarter surfaced as industry wags and Vegas are still trying to figure out the odds of a Sanofi-Genzyme tie-up. Unnamed sources revealed to major news outlets that the French pharma had made an offer in the $67 to $70 dollar-a-share range.

Genzyme execs reportedly believe the company is worth around $80-a-share, which would drive up the deal's price tag by more than $2 billion to around $20.4 billion. According to Bloomberg, there's a high-stakes game of chicken being played, leading IN VIVO Blog to wonder if the lure of $23 million -- CEO Henri Termeer's golden parachute if a merger transpires -- might lead to some rapid eye movements.

Don't blink. You might miss hedge fund Ramius' sweetened offer for Cypress. Last month Ramius offered to buy 90% of Cypress it doesn't already own for $4-a-share, but the company rejected the offer as too low. Blasting Cypress' strategy, Ramius apparently might raise its offer if fruitful takeover talks occur and the division of Cowen Group has the ability to do diligence.

Another number to keep in mind: 100, or if you prefer, $100 million. That's the amount of sales Leerink Swann analyst Seamus Fernandez reckons Lilly will lose this year thanks to an August 12 court ruling invalidating a patent on its ADHD best-seller Strattera. With generic competition imminent, the drum beat for a deal grows ever louder. So much for the company's smaller efforts to buy time with investors.

IVB's favorite number? Try 20, as in this year is the 20th anniversary of our Pharmaceuticals Strategic Alliances conference. (You're going to be there, right?) As the countdown to PSA's uber-networking begins, rest assured IVB's got the available numbers and the analysis all wrapped up in another edition of...



Merck/Alectos: As we note in the July/August issue of START-UP, developing Alzheimer’s drugs ain’t for the faint of heart. Big Pharma is far from opting out the space, but given the difficulties and the very high profile failures we reckon pricey deals a la Pfizer’s tie-up with Medivation for Dimebon will be the exception going forward. Case in point: Merck’s deal this week with Alectos of Vancouver, BC. The two groups will identify new drugs that modulate O-linked N-acetylglucsaminidase (O-GlcNAcase), an enzyme implicated in the development of Alzheimer’s. Alectos, which spun out of David Vocadlo’s lab at Simon Fraser University, could receive up to $289 million, including an undisclosed upfront payment. The majority of the money is biobucks based on downstream research, development, and regulatory milestones. (There are also tiered royalty payments on sales of any products that result from the collaboration—when or if that happens.) Compare those deal terms, especially the undisclosed upfront, with what Medivation garnered in 2008 for Dimebon: $225 million just to seal the deal and another $500 million in milestone payments in a co-development, co-promotion arrangement that had Pfizer and Medivation sharing costs 60/40. Medivation’s drug was much further along at the time of partnering: Phase II versus Alectos’ preclinical molecules. But with the high failure rate of late-stage Alzheimer’s assets, it seems pharma has realized it’s no less risky and much cheaper to partner early and retain 100% of the development rights. Moreover, it’s easier to shrug off an undisclosed upfront than an eye-popping $250 million down payment if development doesn’t exactly go as planned. -- EL

Emergent BioSolutions/Trubion: Emergent said late Thursday, Aug. 12 it would buy the struggling Seattle biotech for nearly $97 million in cash and stock immediately with up to $39 million in possible milestones. The move gives the biodefense specialist, best known for its BioThrax anthrax vaccine, access to Trubion's clinical autoimmune and oncology programs, as well as its alternative protein platforms. The deal comes after a couple years of turbulence for Trubion, whose lead program TRU-015 stumbled in Phase II rheumatoid arthritis trials in 2007. The compound was left deeper in limbo by Pfizer's acquisition of Trubion's development partner Wyeth in early 2009. Pfizer dropped the program this June, but Trubion had since identified another promising candidate, TRU-016, for chronic lymphocytic leukemia. Trubion partnered it with Facet Biotech, which was later acquired by Abbott Laboratories, in August 2009 for $20 million upfront. Adding the the upheaval, Trubion's chairman, president and CEO Peter Thompson resigned in November with one of its investors, Steven Gillis of ARCH Venture Partners, taking the helm. For each Trubion share, Emergent will pay $1.365 in cash and 0.1641 shares of Emergent common stock, which comes to $4.55 a share or $96.8 million. Emergent will pay up to $39 million in cash if TRU-016 or other programs reach various milestones, such as the start of the first Phase II trial for TRU-016. The milestones expire after 36 months. -- Alex Lash

Endo/Penwest: In a deal that will bring it full control over its second-biggest seller, Opana, Endo Pharmaceuticals will buy drug delivery technology partner Penwest Pharmaceuticals for $5 a share, for a total of about $168 million. Endo also announced the filing of an NDA for a new crush-proof formulation of the extended-release version of Opana on Aug. 9. The specialty pharma’s acquisition apparently was driven largely by the opportunity to maximize the company's interest in Opana and Opana ER, indicated for relief of moderate to severe pain in patients who require continuous, around-the-clock opioid treatment for an extended period. The announcement came weeks after a settlement with generics challenger Impax Laboratories over the key patent protecting Opana ER. As a result, Opana ER won't face generic competition until January 2013, enough of a window for Endo to commit more resources to it. While its purchases in the past two years of Indevus and HealthTronics helped the company expand into the area of pelvic health, the acquisition of Penwest indicates Endo also recognizes the need to support its area of greatest success, pain therapeutics (See this recent IN VIVO feature for more.) -- Joseph Haas

PregLem/Merck Serono: This week’s tie-up between privately-held PregLem and Merck Serono for the mid-sized pharma’s Phase II-ready Jun kinase inhibitor bentamapimod shows companies are still willing to walk the outlicensing talk. PregLem’s priority these days is its Phase-III selective progesterone receptor modulator Esmya, in development to treat systemic uterine fibroids. But it turns out several of PregLem's 23 employees had at one time worked at Serono and been involved in the discovery and early development of bentamapimod. Their knowledge helped catalyze the deal, said PregLem’s CEO Ernest Loumaye in an interview with “The Pink Sheet” DAILY. Bentamapimod will move into proof-of-concept trials next year in prevention of post-surgical adhesions. The companies did not disclose financial terms when they announced the deal on Aug. 11. Founded in 2006 and backed through two venture rounds totaling $64.4 million by Sofinnova Ventures, Sofinnova Partners, MVM Life Science Partners and NeoMed Management, PregLem prefers to in-license clinical compounds that focus on women's reproductive health. -- JH

Topcon/Optimedica: As venture firms struggle to fill their own coffers, execs at private companies have been sharpening their pencils and streamlining their portfolios. The most recent example? OptiMedica, a privately-held biotech developing ophthalmic devices and best known for the development of the PASCAL laser technology for the surgical treatment of cataracts. This week the company announced it had partnered its glaucoma and retina assets to Topcon, a Japanese manufacturer of ophthalmic, optometric, GPS and positioning control devices. Terms of the deal were not disclosed but it is apparently the largest acquisition to date for Topcon’s medical division. OptiMedica, which has pulled in close to $55 million in funding from the likes of Kleiner Perkins Caufield & Byers and Alloy Ventures since its 2005 founding, will use the money to support the global launch of its laser cataract surgery system and sharpen its R&D efforts in the same space. Earlier this year the firm revealed the development of a proprietary femtosecond laser designed to improve cataract surgery by automating the most technically demanding steps. -- EL

Epitomics/Apexigen: With the follow-on biologics pathway still murky, many VCs and private biotech execs are pinning their hopes on developing bio-betters, large molecules that hit well validated targets but offer an improvement in efficacy, dosing, or route of administration than existing therapies and don't infringe on existing IP. (This despite the obvious travails of companies such as Trubion [outlined above] and AstraZeneca's MedImmune, whose Synagis follow-on has suffered a set-back with regulators .) On August 12, privately-held Epitomics, which has a proprietary rabbit monoclonal technology, announced it was spinning out to existing shareholders a new biotech company, Apexigen, which aims to develop and commercialize mABs for treatment of cancer and immuno-disorders. The move seems to leave Epitomics, a Chinese/U.S. biotech hybrid backed by Sycamore Ventures, Amkey Ventures, and Kenson Ventures, largely a discovery/fee-for service play, with Apexigen taking on the riskier, more expensive development work. According to the company, Apexigen inherits bio-better programs already initiated by Epitomics, including mABs against VEGF and TNF. No word whether Epitomics or its investors have pitched in with cash to get Apexigen off the ground. -- EL

One Small Biomarker Step for Bapineuzumab

Our boss wouldn't sign off on a business trip to Hawaii, even to cover the International Conference on Alzheimer's Disease in Honolulu. Something about not letting us leave our brains on the beach.

Instead we've been neural surfing from the IVB HQ this week. We spent time on the phone with a couple clinical execs to discuss Johnson & Johnson and Pfizer's release of biomarker data Tuesday, which the firms say is evidence the drug bapineuzumab is having an effect on the underlying processes of Alzheimer's.

The news is not the answer to the $64 million (or several-billion-dollar?) question whether the drug is slowing or reversing cognitive decline through disease modification. No drug has shown that yet, and until one does the frustration that's come with several Phase III setbacks will continue. (We'll have to wait until at least 2012 to know the answer about bapineuzumab.)

But the new bapi data underscores the importance developers are placing on biomarkers to help understand disease progression and guide clinical trial practice in the Alzheimer's field. The Phase III bapi trials are underway and can't be modified, but the data could affect future studies. (We'll examine the effects of biomarker development and the clinical setbacks on Alzheimer's-focused startups in the upcoming issue of START-UP.)

Pfizer and J&J were quick to caution that the data are also preliminary. Taken from Phase II trials that ended in 2008, they need to be confirmed in the global Phase III program that Pfizer and J&J's Janssen Alzheimer Immunotherapy division are running. Company officials said Tuesday that bapi seems to lower the amount of a variant of the protein tau in spinal fluid (CSF) that has been linked to neurodegeneration. (Data are at the end of this post.)

Bapineuzumab itself does not target tau. The CSF measurements are a "downstream" biomarker rather than direct effect, Ron Black, Pfizer's assistant vice president of clinical R&D, told the IN VIVO Blog.

A humanized monoclonal antibody, bapineuzumab is designed to prevent the beta-amyloid plaques that accumulate in patients' brains. But the tau biomarker study, which measured "phospho" tau, or P-tau, shows bapi is also having some effect on a second Alzheimer's pathology. "Recent scientific data suggests both [Aβ and tau] processes might be important," Janssen Alzheimer Immunotherapy's head of clinical development Eric Yuen told IN VIVO Blog. "The initial step may be overproduction or underclearance of toxic Aβ...that aggregate and become more toxic. The increase in P-tau subsequently produces more toxicity to neurons. It's a long process."

Another study released Tuesday showed the predecessor to bapineuzumab, AN1792, also made statistically significant reductions in tau (as well as Aβ). Development of AN1792 was halted after Phase II trials in 2002 when patients were struck with brain inflammation. Researchers continued to follow the patients, however. "The findings give us more basic information about the interaction between beta amyloid and tau in Alzheimer's and may clarify how the disease progresses in the brain," researcher Delphine Boche of the University of Southampton's School of Medicine said in a statement.

When neurons die, the tau from the microtubules inside the neurons is released into the spinal fluid. With less P-tau in the spinal fluid, it's more evidence to suggest bapineuzumab is preventing neuronal death. (The statistically significant data came from 46 patients in two Phase II studies; 27 got bapineuzumab, 19 received placebo.)

But that's a long way from showing positive clinical outcomes. The main Phase II tests for bapineuzumab, run by J&J and Pfizer's predecessors Elan and Wyeth, showed that only patients who did not carry the ApoE4 allele had statistically significant cognitive and functional improvement. That's crucial, because in Alzheimer's trials only such "real-world" measurements, can lead to a drug's approval. It's one reason why the so-called amyloid hypothesis, which holds that to cure Alzheimer's you have to curtail Aβ, is in question these days: There's little evidence so far that fighting Aβ leads to a functional difference to patients.

That's another reason to study biomarkers: the more data researchers gather about the underlying molecular biology of Alzheimer's, the more chance to correlate changes in the biology to improved cognition and function if and when those improvements carry the day in a late-stage trial.

Elan's rights went to J&J in a far-reaching deal last year, and Pfizer got partial rights when it bought Wyeth. Janssen's data are due main trial is expected to end in 2012 and Pfizer's in 2014.

The top-line data from the Phase II CSF tau study pooled two patient populations. They showed a statistically significant decrease (p=0.0270) in P-tau in bapineuzumab treated patients (9.49±2.74 pg/mL) compared with placebo-treated patients (-0.51±3.26 pg/mL). Although not statistically significant, the analysis also showed a trend (p=0.0856) for a decrease in T-tau in bapineuzumab-treated patients (-73.31±32.73 pg/mL) compared to placebo (+9.79±38.95 pg/mL) in the change from baseline to month 12 values.
