Deals Of The Week: New Remedies Sought From Nature And Old Technologies

To help calm many a frazzled J. P. Morgan attendee trying to get to grips with new ideas, technologies and market entrants announced each year at that key U.S. conference, there’s nothing like a return to tried and tested modalities, particularly in drug discovery.

Two deals announced this week in Europe appear to herald just such a return to basics, although on closer inspection these older drug discovery methods – searching through natural product libraries for active substances -- and the use of high throughput screening -- have never really gone away.

The first Europe-centered agreement, between France’s Sanofi and Germany’s applied research institute, the Fraunhofer Institute for Molecular Biology and Applied Ecology, involves  identifying potential therapeutic substances from natural sources, mainly micro-organisms, to boost the number of antibiotics in development.

It might seem old hat: the venerable old-timer penicillin was isolated from natural sources, for example.  Still, the collaborators are introducing a couple of new twists. They are going to work together, as one team in shared labs on analyzing the genetics of micro-organisms, stimulating them to produce new active substances, and identifying those substances with therapeutic potential. It’s part of Sanofi’s drive to get  closer to cutting-edge science and external collaborators.

A new facility will be built on the Institute’s campus to house the researchers. Cross-pollination between this collaboration and Sanofi’s on-going alliance with venture-backed biotech Warp Drive Bio, which is scouring the genome of soil samples for examples of natural products with therapeutic potential could be possible. Under that 2012 deal the French pharma gets right-of-first-refusal for all candidates stemming from the target area of the biotech’s first genomic search.

The German researchers have a secret weapon: access to Sanofi’s huge (150,000-plus samples) collection of micro-organisms built up by predecessor companies like Hoechst and Synthelabo, as well as by its own labs.  The Fraunhofer Institute, a network or more than 60 research centers mainly based in Germany, with 30% of its funding from the German government and 70% from  industry partners, gains from the deal by being able to exploit Sanofi’s collection for non-medical uses with its own partners. In the crop protection area, for instance, Sanofi could develop compounds that have potential as human or animal medicines.

The lack of new classes of anti-infectives nearing the market has horrified many public health experts, who are concerned by the emergence of bacterial resistance to commonly used agents. Thereis  not a lot left in the locker to treat life-threatening infections. So it’s good news that other companies, such as Roche, have re-energized their research efforts in the field.

The week’s second European deal involves the setting up of a European joint venture called Hit Discovery Constance GmbH to conduct high-throughput screening (HTS) for biotech and academic partners, and to act as a storage and management facility for compound libraries.

HTS has been a disappointment to some; nonetheless it is now commonplace throughout industry and is often used to narrow down the choice of compounds likely to bind to targets, which are then refined through computer-based analysis and other processes.

Hit Discovery Constance is based in facilities in Constance, Germany, that have had a long line of previous owners – most recently Takeda Pharmaceutical Co. Ltd., and before that Nycomed SPA and Altana Pharma GmbH. Three European companies – Germany’s Lead Discovery Center, Italy’s Axxam SRL and Belgium’s Centre for Drug Design and Discovery - have set up the joint venture to run a fully-automated robotic screening system using a library of compounds assembled by the partners. Combined with other novel biochemical, bioassay and HTS technologies developed by the three partners, Hit Discovery Constance will be one of the largest screening hubs worldwide.

The revival of technology previously thought to be a disappointment was also featured in the standout deal that kicked off the J. P. Morgan meeting, between RNAi developer Alnylam Pharmaceuticals Inc. of the U.S. and Sanofi’s biotech unit Genzyme.--John Davis

Now, time to get on with deals on other fronts. In a week that saw far more than its fair share of activities, we've culled some of the highlights, below:

Moderna/Alexion: A number of deals were made and broken within the RNA space during the J.P. Morgan gathering, including Moderna Therapeutics Inc.’s news it landed another major partner for its preclinical messenger RNA technology. Rare disease specialist Alexion Pharmaceuticals Inc. will pay $100 million upfront to purchase 10 product options and is taking a $25 million equity stake in the company. Moderna will use its mRNA platform to discover molecules for rare diseases and then transfer all rights to Alexion, which will handle preclinical and clinical work on the molecules. Moderna will be eligible for clinical-stage and regulatory milestones as well as high-single-digit royalties on any resulting products.

This deal is similar to one Moderna struck with AstraZeneca PLC in March 2013 for the rights to more than 40 cardiovascular assets. The British pharma paid $240 million for the options. In both deals, Moderna will be eligible for undisclosed clinical and regulatory milestones, as well as royalties on any products that result. Moderna’s technology is designed to use messenger RNA to spur the production of therapeutic proteins. A day later, Moderna also announced that it was spinning out a satellite company, Onkaido Therapeutics to focus exclusively on oncology. Moderna is providing Onkaido’s first $20 million in capital.--Lisa Lamotta
Regeneron/Geisinger: Cash-rich Regeneron Pharmaceuticals Inc.’s collaboration with Geisinger Health System on studying genetic determinants of human disease is one of the most ambitious efforts to date by a drug company to systematically apply genomic sequencing to the discovery of new drugs.

The deal is broad and long-ranging, initially signed for five years, but with a horizon that could go out 10 years. Announced on Jan. 13 at the start of the J.P. Morgan meeting, it calls for Regeneron to perform the heavy lifting on sequencing and genotyping and for Geisinger to provide samples collected from its patient volunteers.  From Regeneron’s perspective, correlating genetic variations and human diseases could yield insights about disease and biomarkers leading to development of better drugs. Geisinger, at the same time, is looking for funding for its own research programs and to incorporate genetic advances into clinical care of its patients. Regeneron separately but simultaneously said it was creating a subsidiary, the Regeneron Genetics Center LLC, based at its Tarrytown campus, to pursue both large-scale and family-specific genomics studies.

The research collaboration will seek to sequence a minimum of 100,000 patients who are part of Geisinger, which treats three million people a year.  During the initial five-year collaboration term, the Regeneron Genetics Center will perform sequencing and genotyping to generate de-identified genomic data. The size and scope of the study are meant to allow great precision in identifying and validating the associations between genes and human disease. No money changed hands, but Regeneron will pay Geisinger for its services. Down the road, if drugs or diagnostics come to market, Geisinger will receive small royalties on sales of products.--Wendy Diller

Prosensa/GlaxoSmithKline: For our top “No-Deal of the Week,” GlaxoSmithKline has exited its 2009 collaboration in Duchenne muscular dystrophy (DMD) with Prosensa Holding BV, but the Dutch biotech is determined to continue advancing a portfolio of DMD candidates on its own, at least for now.

Few observers were surprised when GSK decided to terminate the partnership Jan. 13, but Prosensa says it hopes to continue developing drisapersen, a Phase III RNA antisense oligonucleotide exon-skipping compound which failed a Phase III trial last September.

In theory, drisapersen and Prosensa’s other candidates, three of which have reached mid-stage clinical development, address the underlying cause of DMD with exon-skipping technology that restores the expression of dystrophin protein. GSK paid $25 million upfront, with the potential for up to $665 million in milestones, in October 2009 for exclusive worldwide rights to drisapersen, as well as options on three other exon-skipping candidates. Although drisapersen demonstrated efficacy, as measured by improvement in the six-minute walk test (6MWT) in two other placebo-controlled trials, the companies announced Sept. 20 that it failed to meet its primary efficacy endpoint in the Phase III DEMAND III study.

Prosensa CEO Hans Schikan did not specify whether Prosensa paid GSK anything to re-acquire its intellectual property rights, including the options GSK had held, but said the multinational pharma holds no downstream rights for any of the DMD candidates. Prosensa earned at least $28 million in milestones under the collaboration with GSK, but Schikan said that cash was secondary in importance to the role GSK played in advancing drisapersen. “After this collaboration with GSK, and thanks to their commitment, we now have the largest database in DMD,” he said. He noted Prosensa probably never would have been in a position to develop this compound in this way. More than 300 patients have been treated in various clinical trials.

Schikan would not be pinned down on whether Prosensa will seek another co-development partner for drisapersen. The first order of business is to meet with stakeholders to see if there is a regulatory path forward for the compound, he said.--Joseph Haas

McKesson/Celesio: Our other notable “No-Deal” was McKesson Corp.’s announcement Jan. 13 that it had failed to complete the acquisition of Germany-based drug wholesaler Celesio AG because it did not attain the necessary 75% share position through its tender offer, despite raising its bid to €23.50 per share from the original €23. The acquisition was an effort to expand McKesson’s global reach, but the outcome was contingent on acquiring a minimum of 75% of shares on a fully diluted basis. The bid was announced in October.

McKesson CEO John Hammergren raised the topic during the company’s presentation to the J.P. Morgan Healthcare Conference, also on Jan. 13, and said redoing the tender offer was not a possibility. As a result, the failed offer “clearly puts us back to the drawing board in some respects.”

“Although we remain optimistic that we will continue to find ways to add value to our company through capital deployment and continued scale, it's not clear to us that Celesio will be part of that,” he said. However, asked if a joint venture with Celesio might be an option, he observed, “We obviously have been talking to Celesio for some time about various alternatives. I think clearly there is an opportunity for us to venture with them and jointly buy. In the past, we had the view that an acquisition and the complete control of the asset would give us faster and better throughput than a joint venture would, but clearly a joint venture would be an alternative to consider.”--Scott Steinke













 

Deals Of The Week Road-Tests Biopharma Options

More options are always better, right? Obviously, that’s a “yes” when it comes to building our dream Tesla Model S. But big biopharma is getting nowhere fast with deals that build in options to license drug candidates.

The number of option-to-license deals executed peaked at more than 30 in 2009, when biotech financing had dried up in the wake of the 2008 U.S. economic meltdown, and has declined every year since, according to data from Elsevier’s Strategic Transactions database. That’s only counting deals with an option-to-license as the main component. What has big biopharma accomplished with its slew of option deals in the last decade and a half? Not much, so far. Even though option-based partnerships can be cheap, they also rarely offer results.

Option-to-license deals, or option-alliances, are often a way of making a half-hearted bet on biotechs’ riskiest, early-stage candidates and technologies. For small biotechs, the extent to which they rely upon these deals can be a sign of their relative fiscal desperation. Option-alliances lock up biotech assets very early, with a high level of continued uncertainty (and development costs) for the biotech and a capped future potential upside.

For pharma, these deals are a bargain – pay a little upfront and part of early-stage R&D costs and then pick up rights to a candidate, or not, typically after clinical proof-of-concept data emerges. Biotechs are able to retain control of their assets for a while longer, potentially allowing them to move development forward faster.

We analyzed all R&D-based option-alliances with a disclosed potential value of $100 million or more. That’s almost 120 deals, some dating back as early as the late 90s. Many of the more recent ones remain active, of course; these deals typically extend over at least three or four years. Most of the remaining deals either expired or were terminated. We could only find seven of these $100M+ deals that actually resulted in option exercises, and some of those later blew up in the clinic.

GlaxoSmithKline is a nice case in point. It has been one of the most active R&D options dealmakers, with at least 18 of these deals, most of which were initiated from 2006 through 2009. A few of GSK’s option-alliances have resulted in abject disappointments – most prominently with Nabi Biopharmaceuticals for the smoking cessation product NicVax, which failed in Phase III. Last year, Nabi merged with Biota.

Others got shunted to the side due to changes in GSK priorities (a $1.5B bio-bucks deal w Targacept was terminated in 2011 as the pharma left neuroscience) or as biotechs became defunct (after a $1.2B bio-bucks deal in 2007, Epix Pharmaceuticals then slid out of existence in 2009). Several of GSK’s option-to-license deals were done under its Center of Excellence for External Drug Discovery (CEEDD), which silently sank under waves of corporate restructuring around 2010.

(GSK is undeterred from experimenting with its approach to external, early innovation. This week it picked the first set of winners from a discovery-stage academic competition. See below for further details.)

The pharma does have several ongoing option-alliances, including at least four with companies that recently IPO’d. One is an option to back-up compounds for Duchenne muscular dystrophy (DMD) from Prosensa; GSK is partnered with the biotech on lead compound drisapersen, which failed in Phase III testing to treat DMD in September. Optimists are hoping its exon skipping technology has progressed since the first iteration and are looking for an effective DMD treatment among Prosensa’s back-up compounds, some of which GSK can option. Prosensa is the worst-performing 2013 IPO, down 72%.

GSK also has an anti-inflammatory and HCV deal with microRNAi company Regulus Therapeutics, initiated in 2008 and expanded in 2010; an anti-cancer stem cell antibody deal with OncoMed Pharmaceuticals that was for four candidate originally from 2007, but was cut down to two candidates in 2011; and a discovery deal with Five Prime Therapeutics for skeletal muscle diseases and muscle wasting targets and candidates that was originated in 2010 and expanded in 2011.

GSK has exercised its options at least twice, but both times candidates were returned. In 2010, it optioned Anacor Pharmaceuticals’ Gram-negative infection treatment and then subsequently returned it a few years later. That same year, it optioned Traficet-EN (now vercirnon) from ChemoCentryx. This September, GSK returned rights to the candidate for all indications. The pharma retained CCX354 for rheumatoid arthritis, which it also optioned. It may still option a third candidate under the 2006 deal.

Despite keeping a lot of options open, no one’s going anywhere fast. But we’re keeping our eyes on the road, moving ahead to all the latest deals (including loads of academic and discovery partnerships) in this edition of…

Salix/Santarus: The union of Salix Pharmaceuticals with Santarus creates a billion-dollar gastrointestinal specialty pharma that holds U.S. rights to fast-growing diabetes drug Glumetza (metformin extended release). Salix agreed Nov. 7 to pay $32 per share in cash for San Diego-based Santarus, valuing the company at $2.6 billion; its combined annual revenues would be about $1.3 billion based on their most recent quarterly performances. Salix has relied heavily on Xifaxan (rifaximin) for traveler’s diarrhea caused by Escherichia coli infections and hepatic encephelopathy; it produced $514.5 million in 2012 revenues, about 70% of the company’s total product sales. But it says the conjoined entity will be more diversified, with no drug accounting for more than half its revenues. Glumetza, a drug Santarus shares with Depomed, has delivered $131.4 million in revenue to Santarus in the first nine months of 2013. The buyout price represents a 37.8% premium over Santarus’s Nov. 7 closing price of $23.22. Raleigh, N.C.-based Salix had about $817 million in cash at the end of the third quarter, but intends to finance the deal with $1.95 billion in debt and a $150 million revolving credit facility from Jefferies Finance, as well as nearly all of its cash on hand. - Paul Bonanos

Roche/Polyphor: Switzerland-based Roche signed an exclusive global licensing deal to develop and commercialize Swiss biotech Polyphor's investigational antibiotic POL7080 against certain hospital-acquired superbug infections known as Pseudomonas aeruginosa, signaling Roche’s first foray back into antimicrobial development for three decades. Roche will pay up to CHF 500 million ($548 million) for the experimental antibiotic, which has only just entered Phase II testing, the companies said Nov. 4. The world’s largest maker of cancer drugs, which is trying to diversify into other disease areas, will make an upfront payment of CHF 35 million and milestone payments of up to CHF 465 million to the Swiss biotech. Roche said POL7080 belongs to a new class of antibiotics that kills P. aeruginosa, a bacterium found in hospitals and resistant to many antibiotic treatments, by a novel mode of action. It’s the first of a number of novel antibiotic candidate drugs being assembled by research and early development group pRED, which is now under the new leadership of John Reed and focusing on three main areas of unmet medical need: Hepatitis B, Influenza and Antibiotics. The pact with Polyphor is the first demonstration that Roche is back in antibiotics. In contrast, other Big Pharma companies have cut back, including former field leader Pfizer, which closed its antibiotic R&D center in Connecticut in 2011, as well as Bristol-Myers Squibb and Eli Lilly. AstraZeneca, GSK, and Merck remain active in the space. Privately-owned Polyphor discovers and develops macrocycle drugs intended as a complement to classical small molecules and large biopharmaceuticals. Although Polyphor, whose main shareholders are private individuals, doesn’t have any products on the market, its pact with Roche is its sixth deal since 2008. Its three drug candidates developed using its protein epitope mimetics (PEM) drug discovery technology are POL7080; POL6326, a CXCR4 antagonist currently in Phase II and ear-marked for several indications; and POL6014, an elastase inhibitor that’s in pre-clinical studies. PEMs are “medium-sized…, fully synthetic cyclic peptide-like molecules that mimic the two most relevant secondary structure patterns involved in Protein-Protein Interactions (PPIs),” according to the company’s Web site. It adds that they are “among the most potent and selective molecules known to modulate PPIs, GPCRs with large ligand-binding domains, and enzymes.” - Sten Stovall

Endo/Paladin: Endo Health Solutions’ new CEO Rajiv De Silva is making good on following in the footsteps of his former employer Valeant by conducting rapid-fire M&A that adds to the specialty pharma’s business. The Pennsylvania company announced Nov. 5 that it will acquire Montreal-based Paladin. The Canadian spec pharma has over 60 marketed products and will give Endo a jumping off point for building its business in Canada, Mexico, and South Africa. The $1.6 billion deal will be an almost all-stock transaction, with Endo paying CAD$77 ($73.70) per share for all outstanding shares of Paladin, a premium of 20% to Paladin’s share price of $63.91 on Nov. 4, the day before the deal was made public. Paladin shareholders will receive 1.6331 shares of the new company in stock and CAD$1.16 in cash, as well as one share of Knight Therapeutics, a new company. Knight will be spun-out of Paladin and be formed around Impavido (miltefosine), a treatment for the parasitic disease leishmaniasis. Impavido received a positive opinion from an FDA advisory committee in mid-October and has a PDUFA date of Dec. 18. Following the deal, the new company will be re-domiciled in Ireland in an effort to take advantage of a more favorable tax rate. Currently, Endo has a tax rate in the high-20% to 30% range. The new company will have a tax rate closer to 20%. - Lisa LaMotta

Pfizer/Juvenile Diabetes Research Foundation: The Juvenile Diabetes Research Foundation (JDRF) said Nov. 4 it would partner with Pfizer’s Centers for Therapeutic Innovation (CTI) to co-fund up to four jointly selected projects in the fields of immune tolerance, diabetic nephropathy and beta cell health. This is JDRF’s first corporate partnership since it announced a collaboration last year with Novo Nordisk, which will run out of the pharma’s Type 1 Diabetes R&D Center in Seattle. JDRF is the largest charitable supporter of type 1 diabetes R&D; it is currently sponsoring about $530 million worth of research, with $110 million in support last year. Pfizer’s CTI was established in 2010 to help further translational science; it hopes to get its first compound into the clinic this year and to bring two candidates into the clinic every year starting in 2014. CTI works with a network of 24 academic and medical institutions. Financial details of the deal were undisclosed. - Stacy Lawrence

Eisai/Arena: Eisai doubled down on Arena’s weight loss drug Belviq (lorcaserin) by expanding its commercialization rights to most of the world from much of North and South America. That’s despite slow sales in the drug’s first full quarter on the market – only $5.4 million. Insurers have been slow to start to reimburse for Belviq and Vivus’ Qsymia (phentermine/topiramate ER). Under the expanded deal, Arena will receive a $60 million upfront payment and up to $176.5 million in regulatory and development milestones. That’s an increase of $123 million from the milestone amount remaining under the prior agreement. Arena will continue to sell Belviq to Eisai for the U.S. and other North and South American territories for a purchase price of 31.5% and 30.75% of Eisai’s net sales in those regions, respectively. For Europe, China and Japan, Arena will receive 27.5% of Eisai’s net sales, while for all other territories the rate is 30.75%. These rates can increase on a tiered basis. Arena also stands to receive a one-time purchase price adjustment of $1.56 billion based on sales in the territories covered by an agreement; that’s an increase of $185 million from the prior deal. Eisai has exclusive commercialization rights in all countries worldwide, excluding South Korea, Taiwan, Australia, Israel and New Zealand. The partners expect also to investigate Belviq as a smoking cessation treatment. - S.L.

GSK/Various Academic Researchers: With a view to front-loading its pipeline, GSK has selected eight winners in its first Discovery Fast Track competition, designed to translate academic research into starting points for new potential medicines. The contest attracted 142 entries across 17 therapeutic areas from 70 universities, academic research institutions, clinics and hospitals in the US and Canada. The program gives certain researchers the opportunity to partner with GSK and jump-start their research into a development program. The winning projects deal with important unmet medical needs, including antibiotics resistance, diseases of the developing world, and certain cancers. The selected scientists will collaborate with GSK’s Discovery Partnerships with Academia (DPAc) team, the sponsor of the competition, to quickly screen and identify novel compounds to test their hypotheses. If advanced chemical testing is successful, the winning investigators could be offered a DPAc partnership to further refine molecules and assess their potential as novel new medicines. GSK devised the contest as a potential engine for accelerating input into its translational research operation, hoping to entice the brightest minds across North America with the promise of lending its potential to their discovery-stage programs. GSK and the academic partner share the risk and reward of innovation, where the U.K. drug maker funds activities in the partner laboratories, and provides in-kind resources to progress a program from an idea to a candidate medicine. Work on the winning Discovery Fast Track projects will begin immediately and the first screens are expected to be completed in mid-2014. - S.S.

Johnson & Johnson/ Evotec: Johnson & Johnson and Evotec are looking broadly, beyond the current focus on beta amyloid and Tau protein-based mechanisms, to identify new targets for Alzheimer’s disease. Under a collaboration announced on Nov. 8, the companies will seek to identify drug targets that could lead to entirely new approaches to treatment using Evotec’s TargetAD database. At best, the drugs in clinical trials today, if successful, will have modest efficacy for treating symptoms of mild-to-moderate patients, and “delay Alzheimer’s symptoms by a few weeks,” said Evotec’s Werner Lanthaler in an interview. The Janssen-Evotec partnership is much more ambitious than current efforts, both in its approach to how it achieves its goals and the goals themselves, he added. The database is derived from analysis of dysregulated genes in high-quality, well-characterized human brain tissues representing all stages of disease progression, Evotec said. It was built off of tissue contributions from The Netherlands Brain Bank and is “systematized, unbiased, and comprehensive,” said Lanthaler, explaining that by being unbiased, it is agnostic to whether the approach is ultimately an antibody, small molecule, or other kind of compound.  No other companies currently have access to the database, and Lanthaler was cagey in stating whether they would or its use would be exclusive to J&J. But he did say that J&J was the first company Evotec approached when it decided to look for licensees, and it jumped on the opportunity – perhaps in part because the companies have had a previous successful relationship in other therapeutic areas. Janssen will reimburse up to $10 million of full-time employee-based research costs and make preclinical, clinical, regulatory and commercial payments, capped at between $125 million and $145 million per program. Evotec will also be entitled to royalties from sales from any products that emerge from the collaboration. The deal runs for three years, and, on J&J’s side, is being conducted through its California Innovation Center. - Wendy Diller
