Deals Of The Week Looks At Pricing Conundrums

Some technologies are so unprecedented, so spanking new that they present hitherto unknown and formidable commercial hurdles.

Consider gene therapy and non-invasive vagus nerve stimulation. The pricing challenges remain significant, even as these therapies gather regulatory approvals, high-caliber partners and investors.

uniQure BV is the scrappy Dutch biotech that spun out of Amsterdam Molecular Therapeutics BV to win approval for the first gene therapy to be accepted by regulators in the major world markets. After several false starts and near-death experiences, Glybera (alipogene tiparvovec) got EU approval in November 2012 for the ultra-orphan disease lipoprotein lipase deficiency. LPD is a childhood genetic disorder in which a protein needed to metabolize fat molecules is missing, causing a large amount of fat to build up in the blood.

The company has partnered commercial rights covering Europe and selected major emerging markets for Glybera and a mid-stage hemophilia B gene therapy to Italy’s Chiesi Farmaceutici SPA. It has forged ahead with building U.S.-based manufacturing capacity, particularly in advance of an FDA filing for Glybera pending ongoing discussions with the agency. It has hired a CEO and preliminary staffing for its Boston-based U.S. operations, to build out clinical, regulatory, and commercial infrastructure. It’s busy planning launch strategy, identifying patients, and meeting with payers.

But there’s a problem. We asked uniQure’s CEO, Jörn Aldag, how he planned to price his gene therapies. Our discussion focused on the hemophilia B treatment, next in line for approval. Aldag noted that, unlike the long-acting factors being readied for market by Biogen Inc. and others, where patients may be able to infuse every other week, “we’re offering a one-shot treatment. The patient would not have to come back to the hospital for many, many years.”

Aldag said ten patients in the first hemophilia B Phase I/II trial, still ongoing at St. Jude Hospital in Memphis, TN, have been treated and required no or significantly reduced prophylactic treatment for up to three years.

This is truly wondrous news for patients with hemophilia B. The issue is that each gene therapy carries an unknown duration of effect.  Will those patients enrolled in the St. Jude trial require a booster next week? Or will they continue for another 3 years, 10 years, indefinitely?

Aldag is grappling with the same issue with Glybera, and now Chiesi is weighing in on the discussions. The options they’re considering boil down to whether to ask for a front-loaded “down payment, or do we ask for annuity payments,” says Aldag, describing a system of payments over time. He allows that the pricing paradigm will change when he moves beyond orphan monogenic diseases, for instance, into larger-population neurodegenerative disorders, such as Parkinson’s disease (uniQure has a Parkinson’s gene therapy which is currently in Phase I/II). “Those would not command as high a price.”

New-Jersey based electroCore LLC (which, like uniQure, was absent the day the teacher taught proper capitalization) is at the forefront of companies developing noninvasive vagus nerve stimulation (VNS) devices – DOTW is typically all-pharma, all-the-time, so forgive our excursion into the world of medical devices. These are small, hand-held devices that deliver a mild electrical charge to the cervical branch of the vagus nerve. VNS technology has been around for decades in implanted devices – some are even FDA approved for partial-onset epilepsy and refractory depression. But implanted VNS is expensive and carries the risk and inconvenience of surgery. And that has inhibited adoption of the technology.

But VNS has been validated as a safe and effective alternative to drug therapy in a broad range of indications, says Mir Imran, a device inventor and founder of InCube Ventures. Imran told us that, with regard to epilepsy, the efficacy of VNS is comparable to pharmacotherapy, with similar success rates of 30% to 40%.

So noninvasive VNS, electroCore CEO J.P. Errico believes, “is something that can compete [with drugs] at the front end of the continuum of care.” Merck & Co. Inc.’s Global Health Innovation Fund, which was attracted to electroCore’s technology because it can be used in the home setting, fitting in with the fund’s focus on technologies featuring flexible access to care, apparently agrees. Merck’s fund joined with two other private equity groups to fund electroCore’s $40 million series A round earlier this year.

electroCore is currently in four registration trials for indications including cluster and migraine headache. It expects to launch its first product, gammaCore, in the U.S. in the next two years. Besides headache, electroCore is developing gammaCore for anxiety, epilepsy, depression, as well as for inflammatory conditions like gastroparesis, COPD, and asthma.

But there’s a rub. Because essentially the same device would be used across all indications, patients using it for migraine who hear about a trial testing the device in, say, gastroparesis, might try to self-treat for gastroparesis. Patients using the device for one indication may also experience the unintentional resolution of symptoms in other indications. Patients could possibly even share devices. Any of these scenarios could cut into the commercial opportunity for electroCore.

Errico says electroCore might offer different products based on specific usage. “If the person’s going to use it only to treat acute headaches, there may be a cheaper entry point for them than if they’re going to need the device to last for a very long period of time and use it over a period of years,” he says. But usage could be further complicated by electroCore’s preliminary finding that the amount of required treatment is not so much dependent on the specific disease state or severity; it’s more related to individual patient response.

All of this informs how the company will model usage of its products, and therefore, how to appropriately price them.

Both uniQure and electroCore need to proceed carefully. A miscalculation could be costly. -- Mike Goodman

Here are some of the deals that caught our eye this week . . .

Celgene/OncoMed: Celgene Corp. struck again Dec. 3, inking its ninth deal this year and adding to its impressive roster of oncology partners. This time, the company will put up $155 million upfront in a six-program partnership with OncoMed Pharmaceuticals Inc. centered on a Phase Ib monoclonal antibody being tested in pancreatic and non-small cell lung cancer. Celgene will also make a $22.3 million equity investment in OncoMed. In exchange, Celgene will receive option rights on six novel anti-cancer stem-cell therapeutic candidates, including the lead asset, demcizumab (OMP-21M18), a humanized MAb inhibitor of Delta-Like Ligand 4 (DLL4) in the Notch signaling pathway.

The deal also covers five preclinical or discovery-stage large-molecule programs - Celgene gets full license to one of the preclinical programs, while OncoMed retains U.S. co-development and co-commercialization rights on the other assets. If Celgene options demcizumab, the companies will share global development costs, with Celgene covering two-thirds of the expense. If the drug is approved by FDA, they will co-commercialize it in the U.S., with 50/50 profit sharing. Outside the U.S., Celgene would develop and commercialize the antibody, with OncoMed eligible for milestones and tiered double-digit royalties.

Celgene also gets rights to OncoMed’s preclinical anti-DLL4/vascular endothelial growth factor bispecific antibody, as well as four preclinical or discovery-stage biologics programs that target other cancer stem cell pathways, including RSPO-LGR. Celgene’s exclusive license is to one of those four biologics programs. For the four programs not outright-licensed by Celgene, the Redwood City, Calif., biotech gets terms similar to those negotiated for demcizumab – two-to-one global development cost-sharing with Celgene covering the larger portion, 50/50 U.S. co-commercialization with profit-sharing, and mid-single-digit to mid-double-digit royalties on sales outside the U.S. For the licensed program, OncoMed can earn mid-single-digit to mid-double-digit royalties on worldwide sales. Total earn-outs could exceed $3 billion.-- Joe Haas

Forest/Merck: Forest Laboratories Inc. will acquire U.S. commercial rights to Merck & Co.’s antipsychotic Saphris (asenapine) for $240 million upfront and undisclosed sales milestones, marking CEO Brent Saunders first business development initiative since becoming CEO in October. The companies announced the deal Dec. 2, the same day Forest announced a $500 million cost reduction program intended to right-size the company and $1 billion in new financing to fund share repurchases and additional bolt-on acquisitions.

Saphris, which was approved by FDA in 2009, generated sales of $150 million in the 12 months ended September 2013, according to Forest. Forest expects its expertise in marketing drugs for central nervous system disorders will help to drive growth of the brand. The drug will be marketed by Forest’s existing commercial team, which already sells the antidepressant Viibryd (vilazodone) and expects to soon be selling Fetzima (levomilnacipran), a serotonin and norepinephrine reuptake inhibitor (SNRI) that was approved for depression in July.

Having the three CNS drugs together in one portfolio is a powerful proposition that creates upside without adding cost, Saunders said. It is not only more efficient, but it also improves the quality of Forest’s sales team, he added. “When our rep walks into a psych office, they are not just a one-product detail. They have a whole portfolio of products to talk about depending on what is on the physician’s mind, and it creates a much more relevant rep,” he said. That multi-product commercial strategy is one Saunders would like to carry over to areas like gastrointestinal disease and cardiovascular disease.-- Jess Merrill

The Medicines Company/Rempex: The Medicines Co. has lost no time enlarging its fledgling infectious disease franchise by acquiring Rempex Pharmaceuticals Inc. and its pipeline of assets targeting serious bacterial infections. For $140 million upfront and $434 million in development, regulatory, and commercial milestones, MDCO acquires several anti-infective assets in varying stages.  Chief among them is Carbavance, a Phase II-ready drug for IV treatment of hospitalized patients with multi-drug resistant gram negative infections. It will enter registration studies in 2014. MDCO will market Minocin IV (minocycline for injection) for resistant infections due to Acinetobacter, a pathogen that is especially prevalent in intensive care units. MDCO plans to submit for U.S. approval an improved formulation of Minocin IV in 2014. Finally, MDCO will continue Rempex’s discovery programs focused on beta-lactamase inhibitor-based combination products designed to overcome resistance mechanisms in gram-negative organisms. The Rempex assets complement MDCO’s oritavancin, which targets gram positive complex skin infections and which is slated to file for a late 2013 NDA and a first quarter 2014 MAA in Europe.

The acquisition gives MDCO high-caliber antibiotic discovery and development capabilities to supplement its own development and commercialization strengths. It also gives MDCO a marketed product to better leverage its infectious diseases salesforce, which is typical of the hospital specialist’s deal style, while continuing its interest in early-stage assets that first came to notice with its licensing last February of Alnylam Pharmaceuticals Inc.’s ALN-PCS, a PCSK9-targeting RNAi agent for dyslipidemias. -- Mike Goodman

Roche/Molecular Partners: Roche and the Swiss biotech Molecular Partners AG have signed a research collaboration and licensing pact to discover, develop and commercialize therapeutics using the privately-held biotech’s DARPin platform. DARPins are non-antibody-based small proteins engineered for target binding to hone in on and penetrate deep into solid tumors, making them ideal targeting vehicles to deliver toxic agents to tumors to kill cancer cells. Under the deal, Roche has rights to develop and commercialize several DARPin-based products. Molecular Partners will get a starting payment of $60 million, research funding to support the partnership, and potentially more than a billion dollars in milestone payments, as well as tiered royalties on any successes.

The alliance signals growing interest in the DARPins which, due to their ability to bind to different epitopes than antibodies do – and to bind to multiple epitopes or targets in parallel at the same time – might offer a higher selectivity for tumor cells compared to other biologics, including antibody-drug conjugates.  DARPins are based on a class of proteins found in the body called ankyrin repeat proteins, which contain specific amino acid sequences, including a repeated sequence, which bind to proteins. They are easy to manufacture in E. coli, and are highly soluble and stable, according to Molecular Partners. The strategy is similar to that of using armed antibodies to fight cancer, like Roche's antibody-drug conjugate Kadcyla (ado-trastuzumab emtansine). Molecular Partners has already established alliances with Allergan Inc. and Janssen Biotech Inc., among others. -- Sten Stovall

Theraclone / PharmAthene: Theraclone Sciences Inc. and PharmAthene Inc. have called off a merger, announced in August. Under the plan, privately-held Theraclone would have absorbed publically held PharmAthene in an all-stock, merger of equals. The surviving company, which would have retained the PharmAthene name, would have had a clinical-stage pipeline of four assets and several pre-clinical compounds, centered around infectious diseases. According to news accounts, PharmAthene opted out of the deal. Neither party disclosed reasons, but the decision came a week after the federal government’s Biomedical Advanced Research and Development Authority (BARDA) rejected TheraClone’s application for a grant for its pandemic flu program, TCN-032, which has completed a Phase IIa trial. TheraClone will pay PharmAthene a $1 million termination fee. [CORRECTION: PharmAthene will pay TheraClone the $1 million termination fee. Thanks to IVB reader David for pointing out the mistake.]

Theraclone’s pipeline is built from its antibody platform I-STAR (in-situ Therapeutic Antibody Rescue), which rapidly screens memory B cells for rare human antibodies that may be developed into next-generation antibody-based drugs. TCN-032, a recombinant, fully human monoclonal antibody, is also in development for patients severely ill with seasonal influenza. TCN-032 is partnered in Japan with Zenyaku Kogyo Co. Ltd., and the company is evaluating “opportunities to advance TCN-32 with other potential strategic partners for commercial markets,” CEO Clifford Stocks said in a press release disclosing the bad news about BARDA. In addition, the company has asked to meet with BARDA to gain further insight into the reasons for the decision. Theraclone also has an ongoing partnership with Pfizer Inc.  to identify three targets in infectious disease and / or cancer. 

Theraclone also has a recombinant fully human MAB for treatment and prevention of cytomegalovirus (CMV) infections.    PharmAthene, a biodefense company, is developing a recombinant protective anthrax vaccine, SparVax, which is set to enter Phase II trials, and a medical countermeasure for nerve agent poisoning.  It is also developing Valortim, a fully human monoclonal antibody for prevention of anthrax infection.  CEO Eric Richman said the company will continue to “seek to identify opportunities to maximize value for shareholders.” -- Wendy Diller
