In a deal structure that perhaps could best be described as “double-jointed,” new company Tolero Pharmaceuticals has licensed exclusive worldwide rights to MannKind Corp.’s preclinical Bruton’s tyrosine kinase (BTK) inhibitor program, which Tolero believes could yield novel therapies for hematological cancers and inflammatory diseases.
MannKind, of course, is focused almost exclusively on its perennially troubled effort to develop a recombinant inhaled insulin product, Afrezza. The deal with Tolero puts development of the BTK compounds in the hands of the privately held, Utah-based biotech, but allows MannKind the ability to opt back in after Phase I if it likes what Tolero has uncovered. In the case that MannKind opts back, “bio-bucks” slated to go to MannKind under the deal would flow instead to Tolero.
“It’s a different model that we proposed and one that I think MannKind really liked,” Tolero Chairman and CEO Dallin Anderson said in an interview. “It aligned incentives and made our negotiation progress very smooth. I think us proposing a structure that de-risked the opportunity for MannKind and gave them a chance to still be involved down the road helped us with not only terms but also to get to an agreement that makes sense for both parties.”
Tolero will pay an upfront amount with the potential for development, approval and commercialization milestones going to MannKind, along with tiered royalties on any product sales. The parties did not disclose precise deal terms, but Tolero said the upfront and milestones could total $130 million. However, MannKind also retains the right to re-acquire the BTK assets at pre-specified terms up to 60 days after the conclusion of Tolero’s first Phase I study. If MannKind elects this option, it would assume all development and commercialization responsibilities and costs, with Tolero entitled to the potential earn-outs specified in the April 30 deal.
“BTK currently represents one of the most exciting therapeutic targets in oncology, and we feel that our collaborative approach to targeting BTK may uncover some novel utilities not yet fully realized,” Anderson said. Pressed for details on what those additional “utilities” might be, however, the CEO remained mum.
Much about Tolero remains unknown – founded in 2011 and based in Salt Lake City, the firm is not backed by venture capital or institutional investors. Anderson, who noted his background as having co-founded Montigen Pharmaceuticals in 2003 and then selling to SuperGen in 2006 at a significant multiple, would say only that his company is funded by a number of private investors. Its own programs, including two compounds – TP-0413 for cancer-related anemia and TP-0829 for B-cell malignancies – are slated to enter clinical development in the next year and derive from a discovery approach based upon single genetic alterations that drive cellular signaling pathway abnormalities.
Tolero also is not disclosing the specific source of its technology, although Anderson alluded to some research relationships with the academic community in Utah, specifically the University of Utah and Brigham Young University. The company’s website says it “seeks to target diseases from a pathway-centric approach by identifying and developing pathway-specific inhibitors and then identifying specific diseases (i.e., cancer subtype) and genetic backgrounds where these pathway inhibitors exhibit enhanced efficacy.”
TP-0413, which targets signaling involved in the regulation of serum iron levels, a pathway implicated in rheumatoid arthritis as well as cancer, is in advanced preclinical and IND-enabling studies, with a goal of beginning clinical development in the second half of this year. Tolero also hopes TP-0829 will move into the clinic early next year, with potential activity in non-Hodgkin lymphoma, chronic lymphocytic leukemia and multiple myeloma.
Elsewhere, it was a typically busy week on the biopharma deal-making front – let’s get caught up with the latest round-up of:
Sandoz/Fougera: Novartis' generics unit, Sandoz, announced May 2 that it will be acquiring Melville, N.Y.-based Fougera Pharmaceuticals in an all-cash transaction worth $1.53 billion that is expected to close some time in the second half of 2012. Fougera, which produced sales of about $430 million in 2011 and has about 700 employees, will make Sandoz the largest manufacturer of generic dermatology products in the world. For Sandoz, the acquisition was “a strategic bolt-on with synergy potential,” said Jeff George, global group head, in an interview. According to Sandoz, once the acquisition is complete, the generic dermatology unit will take in about $620 million in sales globally, with most of that coming from the U.S. On the worldwide market, the company will compete with the likes of Watson Pharmaceuticals, Mylan, Sanofi and Teva Pharmaceutical Industries. Fougera, previously Nycomed US Inc., was the dermatology business of Swiss-based Nycomed Pharma AS before it was acquired by Takeda Pharmaceutical for $13.6 billion in 2011. Takeda decided to pass on the U.S.-based part of the business because it lacked expertise in dermatology and was uninterested in building out the assets. Since the Takeda takeover, Fougera has remained the asset of private investors – Nordic Capital, DLJ Merchant Banking (a Credit Suisse Group affiliate) and Avista Capital Partners. The acquisition by Sandoz gives those investors a good return with a multiple of about 8.8 times the company’s 2011 earnings before interest, taxes, depreciation and amortization (EBITDA) of $173 million. – Lisa LaMotta
Abbott/Action Pharma/Zealand: Abbott Laboratories boosted the renal pipeline of its soon-to-be-separate pharma division AbbVie by acquiring worldwide rights to Action Pharma’s AP214, a Phase IIb drug designed to treat acute kidney injury that can occur during cardiac surgery. Unlike most licensing deals for pipeline assets, Abbott obtained rights to the drug for a single payment, a $110 million cash transaction that won’t be followed by milestone or royalty payments. (Abbott has made this type of bet at least once before, paying PanGenetics $170 million upfront for a Phase II anti-NGF asset in 2009. Yet there’s one complicating factor: Denmark-based Action had developed the drug using structural peptide technology licensed from Zealand Pharma, another Danish company. In the new arrangement, Action rather than Abbott will pay Zealand DKK 62 million ($11 million), and Zealand is due a royalty in the low single digits if Abbott commercializes the drug. The old agreement between Action and Zealand has been terminated. Abbott will begin a second Phase IIb study on the drug this fall. No treatment has yet been approved for acute kidney injury in patients who have undergone cardiac surgery. Abbott already holds ex-U.S. rights to Phase III chronic kidney disease candidate bardoxolone, licensed in September 2010 from Reata Pharmaceuticals, as well as atrasentan, an internally developed Phase II endothelin-receptor antagonist in diabetic kidney disease. – Paul Bonanos
AstraZeneca/Axerion: AstraZeneca’s new virtual neuroscience drug discovery and development unit reached its first partnership agreement May 1, with a licensing and co-development pact centered on preclinical antibodies for Alzheimer’s disease discovered by Axerion Therapeutics. No financial terms were revealed, but Axerion will receive an upfront payment and research and development funding and be eligible to earn milestones and sales royalties if any compound reaches market. The New Haven, Conn., biotech will work with MedImmune, the biologics subsidiary of AstraZeneca, to optimize and develop antibodies that block the binding of amyloid-beta oligomer to cellular prion protein (PrP-C) in the brain. MedImmune has bought into Axerion’s program, in-licensed from Yale, in the hope that this approach could yield a disease-modifying therapy for one of the most challenging indications currently targeted in drug development. The Axerion partnership is AstraZeneca’s first since it announced plans during a quarterly earnings call Feb. 2 to streamline much of its R&D function, including going to a virtual model in neuroscience. At the time, R&D President Martin Mackay said the pharma’s goal was a “leaner, simpler, more innovative organization with a lower and more flexible cost base.” – Joseph Haas
Merck/Trevena: Pennsylvania-based Trevena announced May 2 that Merck & Co. will be the latest company to utilize its G-protein coupled receptor (GPCR) biased ligand platform. The company hopes to identify ligands that turn on only some biological responses, instead of a whole variety of biological responses, by using what it terms "biased ligands.” The company said that Merck, through a subsidiary, has signed on to use the technology to research biased ligands against an undisclosed receptor. Financial details of the transaction were not disclosed. Trevena, which raised a $35 million Series B round in 2010, has other research under way, including its mid-stage lead compound, a drug meant to treat acute heart failure called TRV120027. GPCRs are protein structures that wind across the cell wall, crossing the cell membrane seven times, and common drug targets. When a ligand binds to a GPCR's extracellular part, it triggers a response inside the cell. – LL
Gilead/AnaptysBio: On the heels of inking a partnership with Celgene in April, AnaptysBio has signed a fifth major pharma partner for its antibody discovery platform. This time, it is Gilead Sciences that wants access to AnaptysBio’s SHM-XEL platform for antibody discovery. The companies announced a partnership to develop novel antibody therapeutics May 1. Gilead will pay an undisclosed upfront fee and pay development milestones and royalties on sales of any drugs that emerge from the partnership. AnaptysBio’s technology platform uses the natural biological process by which antibodies are generated, somatic hypermutation (SHM); the company claims its technology can create antibodies with different antigen-binding regions and better binding affinities. Its other pharma partners include Merck, Roche and Novartis. – Jessica Merrill
Hologic/Gen-Probe: Women’s health-focused Hologic, a developer and supplier of diagnostics, imaging and surgical products, is buying molecular diagnostics provider Gen-Probe for $3.7 billion in cash, to be paid for largely by taking on debt. Adding Gen-Probe’s automated instrument platforms gives Hologic critical mass in the molecular diagnostics market. Hologic already owns a molecular diagnostics platform: the Invader technology it acquired when it bought Third Wave Technologies for $580 million in 2008. That gave Hologic an entrée into the molecular testing space, including its own HPV test – a broadening of Hologic’s core focus in women’s health, which includes mammography and, via its merger with Cytyc Corp. in 2007, cervical and breast cancer diagnostics. Gen-Probe gives the company the automation and menu to grow the diagnostics market more quickly – by implication, something that the Third Wave acquisition failed to do. A buyout of Gen-Probe has been in the air since April 2011, when the company reportedly retained Morgan Stanley seeking a buyer. What’s unclear is why Hologic made its move now. There’s speculation that the deal foreshadows a weakness in Hologic’s business. “Based on their forward-looking diligence [statements], that does not appear to be the case,” says Piper Jaffray analyst Bill Quirk. Clinical adoption of new Hologic’s tomosynthesis breast-imaging platform appears to be keeping pace with expectations. It brought on the Gen-Probe business as “one of the elements in building diagnostics so that it performs like [the] breast health [business], not so that it makes up for [it],” Hologic CEO Robert Cascella told investors. Post-acquisition, 50% of Hologic’s revenues will be in diagnostics, 38% in women’s imaging and 12% in surgical. – Mark Ratner
Royalty Pharma/Fumapharm – Royalty Pharma announced May 2 that it acquired an interest in the earn-outs payable to former shareholders of Fumapharm, which includes an interest in Biogen Idec’s multiple sclerosis candidate BG-12, for $761 million in cash. Based in New York, Royalty Pharma says it is the industry leader in acquiring royalty interests in approved and late-stage pharmaceuticals, including interests in Abbott’s Humira (adalimumab), Pfizer’s Lyrica (pregabalin) and Genentech’s Rituxan (rituximab). Biogen bought out Fumapharm in 2006 for $215.5 million and with it the German company’s lead product, psoriasis drug Fumaderm (fumaric acid esters) as well as BG-12. In April, Biogen announced positive data from the Phase III CONFIRM trial, its second pivotal study in relapsing-remitting MS. The compound was filed for approval in RRMS at FDA in February and with the European Medicines Agency in March. – JAH
