Good Data? $100. Good Product Development? $100. Good Commercialization Strategy? Priceless.

I'm not going to fool anyone into believing I'm a therapeutic product development expert but that's not going to stop me from making a few humble observations in light of the Dendreon "fiasco" of last week which I have no doubt will one day be considered an unfortunate pothole on their road to eventual success.

(though perhaps not before certain current management finds themselves polishing their CVs or retiring to spend their time alternating between their yachts and the courtroom defending their questionable stock trading antics)



I received the following message this morning by email. I don't include it here to promote or endorse or even comment on NWBT, DCVax, Linda Powers, or Toucan Capital in any way -- or in a way that is blind to all the things right or wrong about any of them -- but simply to illustrate the 3 points I want to make below the email.

NWBT HIGHLIGHTS COST EFFECTIVENESS OF DCVAX® IN VIEW OF RECENT IMMUNOTHERAPY PRICING CONCERNS

Northwest Biotherapeutics' (OTC.BB: NWBO)... DCVax® immune therapies for a broad range of cancers (including prostate, brain, ovarian and others) hold the promise, based on available data to date, of being cost effective and priced below other immune therapies while still providing substantial profit margins for the Company and longer survival for patients.

The investor concerns in the news relate to the pricing and reimbursement of Provenge for late stage, metastatic prostate cancer. Provenge is priced at $93,000 for one month of treatment and was approved by the FDA based upon having added 4.5 months of patient survival (to reach overall survival of 25.9 months).

NWBT’s DCVax® will be priced in the range of $37,000 per year for up to 3 years of treatments. In NWBT’s Phase I/II multi-center clinical trial in late stage, metastatic prostate cancer, DCVax® added 18 months of patient survival (to reach overall survival of 38.7 months). DCVax® has previously been cleared by the FDA for a 612-patient, randomized, controlled Phase III trial, although the trial has not yet begun. As is typical before a Phase III trial, the manufacturing processes and product costs have already been determined.
...
...

The key to the substantial pricing advantage of DCVax® is NWBT’s proprietary batch manufacturing process together with its cryopreservation technology for frozen storage of the finished vaccine. NWBT has spent a decade developing and improving its manufacturing and cryopreservation processes. The manufacturing of personalized, living cell products is expensive. But the frozen storage of living cells is quite low-cost – once the specialized freezing technology is worked out for a particular type of cells (the culture conditions, rate of freezing, density of cells and many other factors).

NWBT’s manufacturing methods produce – in a single manufacturing run – a large batch of personalized DCVax® product for 3 years of treatments are much less costly than separate manufacturing runs for each treatment. The technology for freezing the master immune cells (dendritic cells) which comprise DCVax® enables these
cells to remain frozen for years and, when needed, to be thawed and “come back to life” with full potency.

This approach makes DCVax® an "off the shelf” product [for that patient] for several years of treatments after just one manufacturing run. In contrast, Dendreon must do a separate manufacturing run for each one month of treatments. In addition, Dendreon's Provenge product is fresh and not cryopreserved, which limits its shelf life to at most a few weeks.

Another important factor in the cost effectiveness of DCVax® is its simplicity and ease of administration. DCVax® is delivered as a small intra-dermal injection under the skin, similar to a flu shot. As such, it can be administered in any physician’s office or clinic. There is no lengthy intravenous infusion, with the attendant patient discomfort, cost and need for a specialty infusion center. In contrast, Dendreon’s Provenge is delivered by intravenous infusion.

The cost effectiveness of NWBT’s DCVax® is enhanced by the fact that DCVax® is targeting a portion of the prostate cancer market that is 4 times the size of the market segment that Dendreon’s Provenge is currently targeting....


Now this is NWBT clearly blowing their horn - nothing wrong with that - in an attempt to woo back frightened investors. I'm agnostic as to whether any of it is true but it does serve to draw out several points of distinction between what some companies might do to optimize their products for commercial success versus what others might do in an overriding belief that clinical benefit is the only precursor to the happiness of investors, the physician community, patients, and partners.

What I say below is not a commentary, in criticism or praise, on any particular company including NWBT or Dendreon. Many others - Luke Timmerman among the best of them - have provided outstanding and in-depth analysis of the Dendreon story along the way.

I'm only interested in what we as an industry might learn from recent experiences or trends and to perhaps facilitate a useful discussion based on 3 simple observations from someone who has swum in this cell therapy pond for now just over a decade:

1. There is a tendency among some to believe that what we are making (cell-based therapies) are so revolutionary and compelling that the products should almost sell themselves - to investors, partners, regulators, insurers, physicians, and patients.

Of course we know it's not true but sometime we act like it is.

Appligraf and Dermagraft didn't sell themselves to physicians even after regulatory approval. Neither is Provenge apparently-- though they did a good job of selling it to very vocal patient groups. Organogenesis and Advanced Biohealing had to work very long and hard to get profitable reimbursement and market penetration. Dendreon will too.

Investing early in understanding potential clinical adoption hurdles, reimbursement issues, and how the product is and will be perceived not by its champions but by its critics and most importantly, the average agnostic practitioner, is not easy to do because it means spending precious resources long before there is a product to sell but it may mean the difference between a product which eventually sells and one which doesn't.


2. There is a tendency to de-emphasize what I call the "ancillary sciences" around a product -- like lowering the cost of goods, optimizing fresh or frozen storage, cell delivery (e.g., injection/application science) mechanisms, in vivo cell tracking, onsite clinical handling, etc.

Product development science is a science. The science that turns good data into something commercially viable. Not everyone is good at it and certainly this is where a lot of companies fail. PD is not the 'second cousin' in the room of esteemed basic and clinical science.

Take these examples when considering the cellular immunotherapy sector:

Several prominent immunotherapy investigators I have spoken with strongly believe cell-based immunotherapies will require long-term administration to be meaningfully effective -- certainly longer than 3 doses in 3 months. Did Dendreon lock into their clinical protocol too early?

Other immunotherapy companies - like Opexa Therapeutics for instance - create multiple doses for a patient from a single patient collection thus saving considerable expense and creating a better patient experience. Did Dendreon lock into their manufacturing protocol too early?

Other companies are investing heavily in finding ways to extend viable shelf-life of their fresh products or to create cryopreserved versions of their product to optimize its commercial viability.

Imagine a Dendreon that only had to build one manufacturing facility (with a backup CMO) to serve the US market rather than 3 facilities. With a cryopreserved version of the product or a version that had longer than its current limited shelf-life (~72 hours I believe?) that might have been possible.

At every point in clinical development there must be concurrent R&D towards the product's:
  1. science (e.g., MOA, characterization, etc),
  2. clinical effect, and
  3. how to optimize its commercial viability - a big part of which is what we think of as 'product development'.
This is the 3-legged footstool of a commercialization strategy geared for success (credit to Bob Preti of Progenitor Cell Therapy for this analogy).

But 'product development' is also not always about the product strictly speaking and even an expansive definition of product development is only part of a good commercialization strategy.

There is significant component of it that is about studying ways to lower the cost of goods, improving manufacturability and scalability, how hard/easy it is to handle, the patient treatment experience, the physician experience, how it impacts patient's QOL (quality of life), not just what side effects it generates but what side effects it prevents (resulting from other treatments or no treatment) and the cost-savings that generates, etc.

Other cell therapy companies have been more proactive in terms of engaging not only KOLs but average practitioners in a meaningful way that might impact their product and clinical design as well as reimbursement and clinical delivery issues.


3. There is an understandable, largely VC-driven, desire to race forward to the next trial phase when a phase-repeat to optimize or better understand different aspects of the product might be the better way to go.

What's worse? Facing the prospect of not being able to get funding or a partner on the terms one wants for a 2nd phase II or burning through a bunch more money in phase III in an attempt to bring a product to market that isn't market ready? I understand its a tough choice -I'm not saying it's an easy one - but one is certainly more strategic and, as pharma says, is certainly a "de-risking" pathway.

Consider the ratio of products we've seen thus far in the cell therapy industry's short life-span that have been raced to phase III or (worse yet) market only to seriously stumble if not fail when they get there. I can think of 8-10 off the top of my head and there are less than 20 cell or tissue based therapies on the market in US/EU that have received any kind of formal regulatory approval.

Some would argue that this is a prime example of why spinning companies out of academia too early is not beneficial because companies want to minimize exploratory science and lock into a "product" too early. I would argue that this may be true if the problem is understanding the product characterization or mechanism of action but not if your problem is related to how best to develop/optimize the product for commercial viability. Few academics are geared to think this way.

Summary

I certainly don't believe Dendreon failed to identify or consider each and every one of the things they might have done better along the way. I'm sure they did and sure they made calculated judgement-calls about how to approach each one.

Since I'm not a shareholder I don't have to worry myself about being critical of their decisions but rather simply to do what I can to ensure that we as an industry do our best to learn from what - with the benefit of retrospect - may be apparent they did right and wrong.

What are your thoughts? To what extent are the problems that Dendreon has experienced along the way with PROVENGE a predicable result of it being a first-generation product or the result of insufficient focus on critical investigation into the less sexy "ancillary sciences" of product and commercial optimization?

    In vivo cell trafficking just took a leap forward


    Today Celsense, Inc. and the University of Pittsburgh Cancer Center announced that the FDA has authorized the use of the Cell Sense imaging reagent for use in a phase I clinical trial of a dendritic cell caccine to treat colorectal cancer patients.

    This is the first FDA authorization of the use of Cell Sense in patients. Cell Sense is a novel perfluorocarbon tracer agent used to safely and efficiently label cells ex vivo without the use of transfection agents. Labeled cells are then transplanted into the patient enabling researchers and clinicians to non-invasively track the administration and migration of therapeutic cells using MRI. Applications include tracking cells in immunotherapy or regenerative medicine as well as the diagnosis of inflammatory sites by tracking selected populations of immune cells.

    Cell Sense has been studied extensively in preclinical testing with many different human cell types including human cells in animals. For instance, in 2009 a paper was published in Informa's Cytotherapy, in which Celsense’s novel perfluorocarbon tracer agent (product “Cell Sense”) was used to label human DCs ex vivo for the purpose of tracking the cells in vivo post-transplant by 19F MRI. The paper provided an assessment of the technology and demonstrated that human DCs were effectively labeled without significant impact on cell viability, phenotype or function. Furthermore, the labeled dendritic cells were clearly detected in vivo by 19F MRI in a model system, with the labeled cells being shown to migrate selectively towards draining lymph node regions within 18 hours after transplant.

    Many investigators looking at various ways to label cells to enable in vivo imaging have expressed concern that the FDA would delay the regulatory progress of their therapeutic candidates if an imaging modality was introduced.

    This concern is based on numerous reports of MRI contrast reagents, such as the commonly investigated USPIO (ultrasmall superparamagnet iron oxide), deleteriously affecting the cells (see recent paper in Cell Transplantation).

    "We believe that the authorization of this IND will alleviate such concerns and lower the barriers for adoption. The agency’s tangible support for bringing new technologies to bear in the translation of cell-based therapeutics is very encouraging,” s Charlie O'Hanlon, President and CEO of Celsense.

    While there have been approved uses of imaging reagents (e.g., Feridex, etc) with cell therapies in other countries (e.g. Isreal), I believe this may be the first FDA-sanctioned use of a particle-based imaging label with a cell-based therapy. Other approaches to cellular imaging include nuclear imaging reagents and genetically modifying cells with reporter genes such as those provided by CellSight Technologies.

    Imaging labels are capable of providing investigators with data demonstrating where the cells go, at what volumes, and for how long they stay at the target location.

    The industry has been keen to see these kinds of technologies clinically employed but different cell-based labels have created their own technical, clinical, and/or regulatory hurdles. I'm hopeful that Celsense and others like them are now ushering us into a new era where we will eventually be able to use various technologies to monitor and collect valuable data concerning cells after they have been administered as a therapy to a patients.

    Additional resources on the topic of imaging for cell therapies:


    CIRM recently hosted a webinar - "CIRM/RMC Webinar: Imaging Technology for Cellular Therapies. One of the speakers, Dr. Shahriar Yaghoubi from CellSight Technologies, provides an overview of cell therapy imaging with emphasis on PET. Click hear for the archived playback.

    A very interesting article posted today on Harvard's StemBook website. "In-vivo Stem Cell Imaging - Regulatory Challenges and Advances". Nice overview intel from J. Bulte and a snapshot into E. Wirth's (of Geron) perspective re: stem cell imaging.

    A new book from CRC Press edited by Dara Kraitchman and Joe Wu will be out soon. It gathers together different methods for comparison. The issue will remain the sensitivity of the methods to track few cells. "Stem Cell Labeling for Delivery and Tracking Using Non-Invasive Imaging".

    MRI contrast agents can change stem cell proliferation

    There s also a very informative discussion thread on the topic in the Cell Therapy Industry group on LinkedIn.

    Cell Therapies: Commercializing a New Class of Biopharmaceuticals


    Over the past six months I have been honored and pleased to have seen and been part of an increasing focus and attention being paid to the unique manufacturing and bioproduction issues related to cell therapy.

    Certainly it is the Cell Therapy Group's view, that this is both timely and much-needed as more cell therapies reach later-stage. Issues related to larger scale production and lowering the costs associated with it will be critical to successful commercialization of these products. It is encouraging to see both content-providers and and companies involved in potentially bringing solutions to these issues now bringing their focused energies to this sector.

    This focus has come from a number of different sources including conferences focused solely on the topic, companies engaging stakeholders in identifying potential bottlenecks they might be positioned to solve, more conference sessions dedicated to these issues, and now a commitment by one of the leading publications in bioprocessing to engage both the cell therapy industry and the traditional bioprocessing community in stepping up the level of two-way education, dialog, and problem-solving that will be critical to commercializing these products.

    In March/April 2011, watch for a special issue of BioProcess International entitled "Cell Therapies: Commercializing a New Class of Biopharmaceuticals".

    BioProcess International is a publishing leader of cutting edge technologies, improved processes and breakthrough sciences. With this cell therapy focused issue, in partnership with ISCT and others, BPI is launching what we hope will be a regular supplement and increased focus on the unique bioproduction issues related to cell-based therapies.

    BioProcess International aims to accomplish three main objectives with this supplement:
    • Educate the bioprocess and cell therapy market (suppliers and end-users) on the similarities and differences between the two processes;
    • Educate and encourage the investor community to keep increasing their interest and investment;
    • Expedite the commercialization process.

    Distribution will include:
    • BPI's 30,010 qualified readers;
    • Delegates attending ISCT's 2011 Annual Meeting (included in all delegate bags)
    • Delegates attending ESACT 2011 (Chair drop at the Cell Therapy Plenary Session)
    • INTERPHEX 2011 Cell Therapy Roundtable (VIP Invitations, 200 attendees, produced by BPI)
    • BIO 2011 International Convention (BioProcess Theatre - Cell Therapy track)

    If you are interested in advertising, click here for more info.

    While the content for this issue is now being finalized, it you are interested in contributing something to BPI, we are looking for more cell therapy related content. As the cell therapy representative on BPI's advisory board I would be happy to champion it through submission.

    Cheers.

    The LinkedIn Cell Therapy Industry Group - 1,000 members strong

    As some of you may know, much of my recent social media energy has been spent on LinkedIn rather than blogging. This was not a conscious decision but I will admit to finding the immediacy and interconnectivity of the LinkedIn/Twitter combo to be more seductive of my limited time than the more laborious and seemingly more unidirectional facets of blogging. I'm still working on a return to more diligent and regular blogging - we'll see how that goes.

    In any event, today's blog entry is ironically about the very thing which has replaced my blogging in many ways for the interim: the LinkedIn Cell Therapy Industry Group which I founded in July 2008 (about the same time as I launched this blog).

    Primarily due to the outstanding participation of great members, the group has turned out to be what I had hoped would be and I believe has become a fairly valuable resource for those in or interested in the cell therapy industry.

    The group grew exponentially throughout 2010 and we are proud today to announce our 1,000th member. Without his knowledge, Luc Gervais today became the 1,000th member of the LinkedIn Cell Therapy Industry Group.

    Luc Gervais lists himself on LinkedIn as a "Technologist Entrepreneur" but is also a Researcher at IBM Research, Zurich Research Laboratory in addition to being a researcher at the University Hospital Basel.

    He was recently involved in the development of IBM's novel, microfluidic "lab on a chip" technology that uses capillary action to create a potential one-step diagnostic tool, and which could ultimately test for a wide range of diseases and viruses. The chip requires only a small drop of blood, which it draws through tiny channels within the device. The blood reacts with different disease markers to provide accurate diagnoses in about 15 minutes.

    Luc represents what I believe is one of the most exciting signs of development in and maturation of the cell therapy industry. Luc's career has included being a Game Developer at Unlikely Games, a Computational Chemistry Developer at Boehringer Ingelheim Pharmaceuticals, and a Quality Assurance Specialist at Steltor. On LinkedIn, he lists "regenerative medicine" as one of his interests.

    People with the kind of experience Luc possesses are bringing a world of scientific, technical, and commercial expertise to regenerative medicine and cell therapy from outside the sector. This promises to revolutionize the way we think about, develop, and apply our technologies.

    Luc and others like him who are exploding into the regenerative medicine and cell therapy field bring with them the potential for interdisciplinary exploration, the opportunity to draw from lessons already learned in other sectors, and the chance to view our field not just in terms of the incredible potential for new therapeutics which cell therapy represents but how that fits into the broader world in which cell therapy is growing up. A world that includes phenomenal advancements in personalized medicine, diagnostics, theranostics, biomarkers, bioinformatics, the ability to access and interpret personal genomics data, etc.

    I have yet to speak to Luc (this was all posted from publicly available information) but I'm hoping to bring you an interview of him shortly not because being the 1,000th member of the LinkedIn Cell Therapy Industry Group is deserving of any particular attention (and certainly will not rank in his list of accomplishments I'm sure) but because I'm curious about what Luc represents.

    Stay tuned....
