Financings of the Fortnight And the Neverending Venture Round

Somewhere out there, perhaps, is the end of NovImmune's Series B round.

More than a year ago, our friends at START-UP examined the fates of biotechs that had reeled in huge private financing rounds. Giant biotech venture rounds are back with a buzz in 2014 thanks to Juno Therapeutics, which launched in December with a $120 million Series A commitment. Last month it added on with cash from Venrock and Bezos Expeditions, aka Amazon.com chief Jeff Bezos' private money stash.

But in raw coinage, Juno's A round doesn't hold a candle to what NovImmune has raised in its Series B. Novi-who? It's a Swiss antibody developer founded 16 years ago that in 2006 first notched CHF 58 million ($46 million at the time) for its Series B. Eight years and three extensions later, the Series B now stands at CHF 200.5 million, most recently boosted by a CHF 60 million ($67 million) tranche announced February 18 and led by London life science specialists Rosetta Capital, whose partner Jonathan Hepple is joining the NovImmune board.

That makes NovImmune's Series B the largest biopharma venture round with at least one extension raised in the past decade, according to our Strategic Transactions database. FOTF reached CEO Jack Barbut via email, and he said NovImmune has kept the round open this long to create fairness for all shareholders. "This makes the share structure very easy," Barbut wrote. "For employees, common stock options (sweat equity), and for investors, preferred shares, all [have] the same liquidation rights and thus comply with Swiss statutes, which are very stringent on equal treatment for ALL shareholders." 

CEO since 2000, Barbut said when the Series B started, he didn't expect it to carry on this long. He doesn't know if this recent tranche will be the last.

We went back a decade into our Strategic Transactions database to see what kind of precedent there might be for NovImmune. We found 59 private companies whose extended rounds reached at least $50 million. Here are the handful, other than NovImmune, that topped $100 million:

Four of those companies have since gone public and one (Sangart) has gone under, shut down by its main investor, as first reported by Fierce Biotech. Meanwhile, Symphogen is in no hurry to go public, as its CEO told Start-Up in this feature last year.

NovImmune is not only top of the charts for money raised, but it also has no peer in the length of time of the round. None of the companies with blockbuster rounds took more than two years to secure their extensions. A few smaller rounds took longer. For example, Theraclone Sciences began raising its Series B in 2007 as Spaltudaq (we applaud the name change) and brought the total to $50 million about a year ago. Endocyte took five years to raise a nearly $80 million Series C before going public in 2011. And Alvine Pharmaceuticals spent more than four years building its Series A and is now waiting to find out if AbbVie will exercise an option to buy its lead Phase II program in celiac disease or the entire company outright. (If AbbVie does, it would be one of the very few corporate investors to buy out one of its portfolio companies.)

NovImmune's Barbut said his investors expect "some sort of liquidity event" too, of course, but in the nearer term he said the company is focused on finding a partner for NI-0101, its anti-TLR4 monoclonal antibody that has entered Phase I. It would also like to advance its NI-0501 program, an anti-interferon gamma antibody, and commercialize it solo. NI-0501 has orphan status in the US and EU in hemophagocytic lymphohistiocytosis, a deadly pediatric autoimmune disease, and has completed a Phase I study.

NovImmune doesn't seem to have cushioned its cash with a lot of non-dilutive funding. Its biggest deal to date is the outlicensing of an anti-IL17 antibody to Genentech in 2010, no financials disclosed. The candidate completed Phase I in 2013.

So we've got an orphan disease-focused biologics company with multiple, wholly owned clinical assets, a partnership with one top-tier biopharma, and the kind of cash runway that seems to attract more investment these days from the public markets. The IPO market has welcomed every stripe of biotech, from still-preclinical platforms to heavily capitalized specialty plays, in the past year, so NovImmune seems like an inevitable "ask." If its cards are well played -- keep in mind several banks are in NovImmune's investor pool -- an IPO could provide a nice bump for those who didn't have to ride the traditional valuation escalator (or be forced off of it) through later rounds.

We offer a bump, too -- a fist bump to Maureen Riordan, who did much of the work behind the scenes for this column. Without her this week, there would be no...

Melinta Therapeutics: Known as Rib-X Pharmaceuticals until last fall, antibiotic developer Melinta hasraised a $70 million Series 3 round led by existing investor Vatera Healthcare Partners. New investors included Falcon Flight, an affiliate of the Santo Domingo Group, and undisclosed backers. As Rib-X, the firm raised more traditionally named A, B and C rounds last decade. But a failed IPO try in 2011, and a set of new investors led by Vatera, have led to a housecleaning. In November 2012, the company disclosed a $67.5 million "Series 2" funding led by Vatera. Last fall, it unveiled its new name and new executive team, led by CEO Mary Szela. The Series 3 cash will help fund its Phase III study of antibiotic delafloxacin, a differentiated flouroquinolone in testing as an oral, single-dose therapy for uncomplicated gonorrhea. Melinta is aiming for an NDA filing in late 2014. In addition, the money will finance a two-trial Phase III program of delafloxacin in acute bacterial skin and skin structure infections, as well as lead-candidate selection from the firm’s RX-04 discovery program seeking to address serious and life-threatening Gram-negative infections via targeting of novel binding site on the bacterial ribosome. – Joseph Haas

Argos Therapeutics: Immunotherapy is hot, right? Well, yes and no. While the likes of Juno can command above and beyond $100 million in a single financing, cancer and infectious disease immunotherapy play Argos raised a mere $45 million in its February 7 IPO, its second try at launching onto the public markets. And that’s only after it had to dramatically cut the price to $8 a share from a $14 mid-point of its proposed range. It also had to increase the dilution, selling 5.6 million shares rather than the 4.3 million it had proposed. Existing investors bought 1.4 million shares of the IPO, or roughly a fourth of the deal. No word yet if the underwriters will exercise the overallotment, but the share price has largely treaded water since the offering. Argos investors can take some solace knowing the bargain-priced IPOs of 2013 ended up as top performers of the year. What's discounted now might have legs later, as Argos is one of many biotechs with notable clinical milestones in reach this year, as START-UP explored in January. Argos might see a boost later this year when it reports Phase IIb data for AGS-004 for treatment interruption in HIV/AIDS patients, although data due in 2016 -- Phase III survival data in renal cell carcinoma -- is more likely to be game-changing for Argos. The firm also expects this year to start two Phase II HIV eradication studies, one in adults and another in pediatric patients. Argos aims in these trials are ambitious – to eliminate the HIV virus or to reduce it to negligible levels. – Stacy Lawrence

Arrowhead Research: RNAi therapeutic developer Arrowhead said February 19 it grossed $104 million in a follow-on offering, selling 5.5 million shares at $18.95 a piece. Of the several public biotechs that sold $100 million-plus in stock this fortnight -- Ironwood Pharmaceuticals, Macrogenics, PTC Therapeutics and Puma Biotechnology were the others -- Arrowhead's inclusion would have been unthinkable this time last year, when it was bumping along in microcap land and had just a few million dollars in cash remaining. Arrowhead isn't strictly an RNAi developer; it has a peptide-drug conjugate in the clinic, too. But there's no doubt RNA interference, riding a revival of sorts highlighted by Alnylam Pharmaceuticals' giant deal last monthwith Sanofi/Genzyme, is driving the Arrowhead agenda. It's also worth noting that RA Capital, the hedge fund that helped propel the big Dicerna IPO, is also a key investor at Arrowhead as of last spring, having led a $35 million offering at $1.83 a share that recapped the company. With its stock now worth more than 10 times as much (it closed February 20 at $21.90) Arrowhead is pushing hard to get its lead RNAi compound, against Hepatitis B, into Phase II.  While RA, now a 9.9% owner, led a turnover in the company's cap table, it wasn't a bloodbath. Arrowhead's longtime CEO Chris Anzalone is still at the helm, and the board remains the same. – Alex Lash

Pronutria: Pronutria revealed February 13 a $12.5 million Series B round, with unnamed private investors participating alongside Flagship Ventures. CEO Robert Connelly told our colleagues at "The Pink Sheet" that Flagship provided less than half of the new round, while “business entities, individuals and family offices” supplied the remainder. Flagship created Pronutria within its VentureLabs program in 2011, quietly funding it with a $10.8 million Series A round over a two-year period before lifting the lid last October. Much of the Series B, which Connelly said is probably Pronutria's final venture round, will be used for clinical trials on two muscle-protecting candidates that preserve strength in frail, elderly people with sarcopenia, the loss of muscle mass that can occur during periods of hospitalization. The candidates, PN-107 and PN-365, are formulations of the amino acid leucine delivered as small “shot”-sized beverages similar to bottled energy products found on supermarket shelves. The specific pharmacokinetics and efficacy of each candidate, and the effects of their specific balances of amino acids, will be compared with each other in the trials. The company is still deciding on a regulatory pathway for each one, including possibly developing them as nutritional supplements, medical foods or pharmaceutical products, each of which has its own requirements. Initial clinical trials, now underway, are scheduled for completion by mid-year; Connelly said the company also is mulling parallel development of drug and non-drug formulations of similar product candidates. Further down the line, Pronutria is aiming for products addressing the metabolic, gastrointestinal, immune and renal disease areas, as well as beneficial products for patients with rare diseases and those going through chemotherapy. Whatever drug products Pronutria develops will reside in a separate business unit, which will help ease eventual sales or spin-outs. – Paul Bonanos

Technology Marches On, And Financings Of The Fortnight Is There!

Digital future? Sounds expensive.... and confusing! Instead, let's talk about the recent past. What stood out for us in this latest fortnight-plus – extended a bit to accommodate the Thanksgiving holiday and our expanded waistlines – were two vast sums of money for companies plying cutting-edge biomedical technologies that, despite some successes in previous permutations, are still high risk. 

We’ll start with the second, because it’s a more obvious case. The company is Juno Therapeutics, which has rounded up a few programs of cancer immunotherapy under one corporate roof. None of them use the infused-antibody paradigm of Yervoy (ipilumumab), the Bristol-Myers Squibb product approved for melanoma treatment, but the much more complicated dance of autologous cell therapy that Dendreon, with its prostate cancer treatment, showed a few years ago could make it to market. Dendreon also ran into trouble, however, because the dance – removing blood from patients, isolating T-cells, shipping them to a lab, re-engineering them, shipping them back, and re-infusing them into the patient – was more than just putting your feet on the floor in the right sequence. Juno’s backers, to the tune of $120 million and, soon, a lot more (see our blurb below), think the Seattle/New York startup has all the right moves, including improvements to the process and stunning (but small sample size) Phase I data from one of its programs. (Xconomy's Luke Timmerman got the early access and the jump on everyone this week for an excellent long-take on the company.)

The other technology-driven story is the second massive cash infusion for Moderna Therapeutics, the Flagship company that wants to inject modified messenger RNA into patients to spur them to produce their own therapeutic proteins. Moderna simmered sotto vocce within Flagship for a couple years until late 2012, when it emerged with a $40 million commitment. Still years away from clinical proof of concept, it almost immediately secured a licensing deal with AstraZeneca with a $240 million upfront that gives AZ rights to cardiovascular and metabolic programs that emerge from Moderna. 

Which brings us to the week before Thanksgiving, when Moderna added to the pile with a $110 million Series B round from Flagship and a raft of undisclosed backers. We’re a long ways from learning if Moderna’s ambitious idea works, but if it does, it will have to overcome a hurdle that has bedeviled many other companies – often extremely well-funded, too – using RNA-based therapeutics. Those oligos don’t hold up well in the body. Delivery is hard. 

When two researchers won the Nobel Prize in 2006 for their discovery of RNA interference, the biotech world seemed well on its way to developing therapeutics based on the gene-silencing technique. Two companies in particular, Sirna Therapeutics and Alnylam Pharmaceuticals, seemed poised to battle for years. Not quite. Merck & Co. bought Sirna for a cool billion dollars, and it was never heard from again. Alnylam’s rich alliances with Big Pharma came to a crashing halt at the end of last decade.

Alnylam was left to clean up the mess with a big restructuring, but it has steadily rebuilt value, and it recently scored notable Phase I data for a program based on its subcutaneous delivery technology. Its share price has rebounded and at $62.98, it’s nearly twice as high as it flew in the heady days of the ‘00s, before its pharma partners abandoned ship. 

So what to make of these new blockbuster financings? Juno is building upon the rollercoaster experience of Dendreon, even hiring Dendreon's former COO as its CEO. Its investors apparently think nothing short of a full financial blitz will make autologous cell therapy 2.0 a winning version. And Moderna has enough cash now to hand-deliver every dose to every patient on a gold-embossed platinum serving tray. And to get into patients' bodies, they might be able to use a subcutaneous approach, too. 

What will be the next frustrating biotechnology to spur a new round of hopeful spending? When the money flows, you'll certainly be able to read about it in....

Juno Therapeutics/Argos Therapeutics: Hello, cancer immunotherapy. The big Series A financing news this week – this year? – was Juno’s $120 million haul to help the company develop and commercialize not one, not two, but three autologous immunotherapy platforms from two rival research institutions. Autologous is like the high-profile Dendreon: T-cells are removed from the patient, genetically souped up in a lab to recognize and kill cancer cells, then re-infused into the patient. The top-line investors in Juno are ARCH Venture Partners and the Alaska Permanent Fund, which invests that state’s oil revenues. Which means Juno – perhaps a clever way to give Alaska and its capital city naming rights? – is cashing in on former Governor Sarah Palin’s successful campaign to raise taxes on oil companies. That tax hike is now the subject of a major political battle, by the way. But we digress. Alaska’s fund managers won’t have a Juno board seat, which means ARCH’s Robert Nelsen is the main money man to herd cats as Juno’s riches are disbursed to folks at Memorial Sloan-Kettering Cancer Center, the Fred Hutchinson Memorial Cancer Center, and Seattle Children's Research Institute. Nelsen tells us that the groups will continue to run their own cancer immunotherapy programs under Juno’s roof, and “may the best data win.” (The Sloan-Kettering folks are unveiling at ASH this weekend a study that brings the percentage of Phase I patients treated with MSKCC’s CART-19 immunotherapy who had a complete response to 88%, or 15 of 17: basically their cancer disappeared.) What’s more, Nelsen says a Series B round “larger than the Series A” is about six months away. We’ll have more on Juno in this week’s issue of "The Pink Sheet", and in the upcoming Start-Up magazine. Meanwhile, at the other end of the funding rainbow, Juno competitor Argos Therapeutics, which has been plugging away at autologous immunotherapy for more than a decade, also had funding news. It topped up its Series E round to $60 million as it continues a pivotal trial in renal cell carcinoma. The first tranche of the E round came in August and included warrants. Argos withdrew an IPO bid in 2012 and instead brought in a Series D round. Other than both working on autologous immunotherapy systems, Argos and Juno have another connection: Argos’ recent backers included Russian and South Korean pharma companies, which mean Juno’s investors can see Argos’ investors from their kitchen window.  – Alex Lash
 
Xencor: Dilution was the headline for the IPO of antibody company Xencor. It priced December 3 at one-third of the mid-point of its original range, and to compensate it doubled its shares sold, and then some. It first filed to raise $75 million by selling 5 million shares at a mid-point of $15 each; it actually raised $70 million by selling 12.7 million at $5.50. That’s despite existing investors, which include MedImmune Ventures and HealthCare Ventures, committing to buy about $20.5 million, or 29%, of the IPO. Investors are demanding deep discounts as the biotech IPO market has softened this fall, so much so that it was a bit of a surprise Xencor made it out at all. Before it got the deal done, Xencor postponed its IPO, as did at least five other biotechs leading up to Thanksgiving. The Xencor offering was originally slated for Nov. 14. The worry for investors is that bankers are now scraping the bottom of the barrel. Perhaps the typical momentum of January’s JPMorgan conference can breathe a bit of life back into IPOs – if the right companies come along. (For a detailed look at the 2013 IPO strategies of OncoMed Pharmaceuticals, bluebird bio, and Ophthotech, check out this Start-Up feature.) At least for Xencor, the immediate investor upside of a deep discount is the potential for money left on the table. In its first day of trading on Dec. 3, Xencor got a 52% bounce, to $8.64 per share. Longer term, Xencor’s fate likely hangs on lead candidate XmAb5871 to treat rheumatoid arthritis, which won’t see a significant milestone until Phase Ib/IIa data due in the second half of 2014. A Phase IIb proof-of-concept trial would follow in the first half of 2015, with partner Amgen Inc. having data in hand in 2017 to determine if it will exercise its option. – Stacy Lawrence
 

Sitari Pharmaceuticals: The joint venture that Avalon Ventures and GlaxoSmithKline announced this spring hatched its first company November 22. The two staked Sitari, which will focus on developing a drug therapy for celiac disease based on research at Stanford University, to a $10 million Series A financing. The $10 million is not a straight cash investment, Avalon Managing Director Jay Lichter told "The Pink Sheet" DAILY. Avalon provides $3 million in cash, while GSK will provide up to $7 million in both cash and in-kind services. Using intellectual property licensed from the Stanford lab of Chaitan Khosla, Sitari will attempt to address celiac, an autoimmune digestive disease caused by intolerance to gluten, by inhibiting the transglutaminase 2 (TG2) pathway. Avalon will transfer tools from the Stanford labs to Sitari’s La Jolla, Calif., location where the GSK chemical libraries will be screened for potential TG2 inhibitors. That will be the starting point of the discovery work, along with considering compounds discovered by Khosla’s team, to determine which chemical scaffold might work best along with other pharmacodynamic factors, Lichter said. The company is years away from selection of a clinical candidate, however. At the time of selection, GSK will have the option to acquire the company or let Avalon take it forward on its own, said Pearl Huang, GSK’s global head of Discovery Partnerships with Academia (DPAC) unit. Huang said $10 million likely will be the standard A round for the companies co-founded by GSK and Avalon, based on both partners’ experience of what it takes to get to candidate selection. – Joseph Haas
 
5am Ventures: The San Francisco Bay Area firm said December 3 it has closed a $250 million fund, its fourth. It’s 20% larger than the group’s third fund, which closed in 2009. Four years between fund closes isn’t bad for an early-stage investor, although as managing partner Andy Schwab told Start-Up last year, “We’re realistic that not all of our companies can be two professors and an early-stage idea.” The firm has reached exits through investments in new companies that were vehicles for mature technologies, such as the Alza pain patch that was spun out and re-jiggered by Incline Therapeutics. 5am cashed out when The Medicines Co. bought Incline in 2012. It’s also had success extending a franchise. It sold Ilypsa in 2007 for $420 million to Amgen, which wanted the startup’s phosphate binder to treat chronic kidney disease. 5am and its syndicate partners spun out of Amgen some of the extra Ilypsa assets into a new company called... Relypsa. (They’re not called 5am for nothing; you’ve got to get up early to be that clever.) Amgen eventually shelved the Ilypsa program, but Relypsa made steady progress and raised north of $150 million in venture cash. It went public this fall, six years after its spin out. Relypsa also dampened its IPO ambitions, going out at $11 a share instead of $16 to $19, and raising $80 million (with insiders buying about a quarter of the shares) instead of roughly $120 million. (Shares closed at $19.60 on Dec. 5.) The new fund keeps the same managing partner lineup of Andy Schwab, Scott Rocklage, and John Diekman.  – Alex Lash
 
Best of the Rest (Highlights of Other Financing Activity This Fortnight): Continuing its focus on drug assets, Versant Ventures will create the biotech incubator Blueline Bioscience, which will spin off start-ups to which Celgene holds an option to buy... Versant also funded the latest Inception spin-off, Inception 4, an ophthalmic company that secured a joint research and option agreement with Bayer...Visterra added $8.1M to its Series A, which now totals $34.2M, and concurrently in-licensed dengue fever IP from MIT…Despite losing GSK as its Fabry disease partner, Amicus Therapeutics was busy: the company restructured its financial and corporate structure, announced $40M in new equity and debt financing, and acquired a lead ERT for Pompe disease in its takeover of Callidus Biopharma…Horizon Pharma netted $144M in a private senior notes sale, $35M of which will fund the purchase of exclusive US rights to AstraZeneca’s pain drug Vimovo…and Gilde Healthcare closed a $200M third fund dedicated to home- and digital-health, diagnostics and medtech, and pharmaceuticals. -- Amanda Micklus
