$10M Tricorder XPRIZE set to launch in 2012

Last week we heard more from Eileen Bartholomew of the XPRIZE Foundation about the anticipated 2012 announcement of the Tricorder XPRIZE. Named after the universal medical diagnostic from Star Trek, the device should allow consumers to diagnose themselves, enabling people to become “CEOs of their own health.” There’s a huge potential for microfluidics to be involved with a point-of-care device like this, especially since lab-on-a-chip systems could facilitate ease-of-use and require smaller sample volumes (e.g., a fingerprick of blood vs. a vial of blood that would need to be drawn by a professional).

Specs so far:
  • Usable by consumers without aid from medical professionals
  • Single device with the ability to diagnose 15 diseases: 12 core-set diseases + 3 elective-set diseases. Examples: Hypertension, urinary tract infection, sleep apnea, sexually transmitted illness (STI)
  • High precision
  • Diagnostic results within 3 days
  • Probably linked to a mobile device like a smartphone (note the contest is being underwritten by Qualcomm)
Timeline
  • Expected prize announcement in 2012
  • Duration of competition expected to be ~ 3.5 years long

The diagnostic sounds similar to several devices already out there (some launched, some in development) such as the AgaMatrix iPhone-connected glucose sensor, the Abbott i-STAT handheld blood analyzer, Boston Microfluidics’ STI diagnostic, and the Zeo sleep monitor, but with more demands in terms of usability and the number of features integrated into one device.

Will the XPRIZE motivate existing companies to collaborate? Currently many are struggling to launch a test that outputs one or two results, never mind 15. I also wonder how the 15 diseases chosen will affect marketing for the device. What if you’re a relatively healthy person who only needs 3 out of the 15 functions? Would you pay more for an all-in-one device like this, or are you more likely to buy individual tests based on your needs? How much use will be symptom-driven (urinary tract infection) vs. long-term monitoring of a known condition (hypertension) vs. screening (STIs)?

Are you planning to enter the competition?

Gajus Worthington on the early days of Fluidigm

Recently I ran across this Stanford video of Gajus Worthington, co-founder and CEO of Fluidigm. Recorded in 2004, it’s a behind-the-scenes snapshot of the early years of the company, after they’d launched their first products (in protein crystallization) in 2003. Over the past decade Fluidigm has gone from fundraising to becoming a public company with a 2010 revenue of $33.6 million.

One quote grabbed me:

“We did this wrong, if you read the textbooks. You’re supposed to figure out what the market opportunity is, then you’re supposed to go out and find technology, and build a team, and all that kind of stuff.  Right. We didn’t do it that way.

We did it, classically, the way you’re not supposed to, which is you find a technology, you get obsessed with it, and you go running around trying to figure out what can I do with it. Well I submit to you that that’s the way most technology companies work.

That’s the way it worked with the laser, that’s the way with lots of other components. You have some kind of technology, you get a bunch of smart people who are obsessed with it.  And ultimately they find something useful they can do with it. It’d be nice to do it the other way, but unfortunately I really don’t know of any examples where that has transpired. ” — Gajus Worthington, CEO of Fluidigm

I tried thinking of biomedical technology companies that started with a market opportunity first, and then developed solutions. I couldn’t come up with any in the microfluidics space. (Although it is hard to know the backstory behind how companies match product and market.)  Do you have any examples of a team starting with a problem, evaluating a range of solutions (microfluidic and non-microfluidic), choosing to go with microfluidics, and then building a microfluidics team?

Microfluidics can control how stem cells communicate

journal.pone .0022892.g001 Microfluidics can control how stem cells communicate

A-B. Microfluidic perfusion device. C. Microfluidic perfusion systems use flow to fine-tune the relative significance of convection, diffusion, and reaction.

Exciting to see the work of Dr. Katarina Blagovic from the Voldman group at MIT published in PLoS ONE last month: “Microfluidic Perfusion for Regulating Diffusible Signaling in Stem Cells.” Katarina continued and extended the work begun during my Ph.D. (I’m a co-author), and it’s wonderful to see the ideas we discussed become reality!

In diffusible signaling, cells communicate with each other by secreting signaling molecules which diffuse into the surrounding liquid before being taken up by those same cells or neighboring cells via receptors. Cell signaling is especially important for stem cells because it can determine how a stem cell specializes into various tissue types. Traditionally cells are grown in Petri dishes in standing liquid. In these conditions, the chemical makeup of the environment around the cells is constantly changing as cells secrete and take up a complex array of signaling molecules. It has been challenging for biologists to experimentally probe the details of these closed-loop interactions: what molecules are secreted when, which cells receive the signals, and what effects do the signals have on the cell?

Enter microfluidics. This paper shows how microfluidics provide a new tool for biologists to interrogate diffusible signaling loops. The idea: for cells grown under continuous, non-recirculating microfluidic perfusion, most secreted signaling molecules are swept away before binding to nearby cells. This continuous clearing enables more strict control over the cell’s environment by allowing the researcher to specify what molecules are perfused into the cell culture. In engineering terms, you have more control over the inputs (signaling molecules) to the system (the cell).

Not only did Katarina show that continuous flow can disrupt diffusible signaling, she was able to uncover a specific biological result which suggests that FGF4 is not the only cell-secreted molecule needed for differentiation of the stem cells to neuroectoderm (cells that gives rise to our nervous system during development).

On the commercial front, CellASIC, a company spun out of Luke Lee’s lab at Berkeley, has created a series of products to support microfluidic perfusion culture. And Fluidigm is developing a stem cell culture chip.

NIH / DARPA solicit proposals for human-on-chip platforms to accelerate drug development

DrugChipCollage 1024x445 NIH / DARPA solicit proposals for human on chip platforms to accelerate drug development

Fantastic to hear about a new, substantial U.S. government funding effort in microfluidics research! Last month a joint effort between the NIHDARPA, and the FDA was announced to develop human-on-chip platforms to test drug candidates more efficiently and accurately. The NIH and DARPA are soliciting proposals separately from all types of research organizations (academic, industry, government, other) and each agency plans to commit up to $70 million to the effort (up to $140 million combined).

A big problem in drug development is that current methods for testing safety and efficacy are either cheap and inaccurate (in vitro experiments, animal studies) or more accurate and very expensive (human clinical trials cost $20k – $50k per patient). Often a drug works in a mouse but doesn’t work in humans, leading to millions lost on failed clinical trials. The hope is that microphysiological environments mimicking human tissue and organ structure may enable more accurate assessment of a drug’s performance at much lower cost.  These chips wouldn’t replace clinical trials, but might allow us to hone in on effective drugs earlier in the development process, saving time and money.

DARPA has already begun soliciting proposals, and abstracts are due in just a few days (Oct 27, 2011).  Full proposals are due on Dec 12, 2011. To apply, see more information here and here.  There’s also a teaming website here to help facilitate collaboration. From the DARPA website:

DARPA is soliciting innovative research proposals to develop an in vitro platform of human tissue constructs that accurately predicts the safety, efficacy, and pharmacokinetics of drug/vaccine candidates prior to their first use in man. Alternative testing methods that rely on isolated human cells hold the promise of authentic human responses to candidate drugs, vaccines, and biologics. Recent research has shown that three-dimensional constructs of one or more cell types are able to reproduce relatively authentic human tissue and organ physiology in an in vitro environment. As a result, DARPA seeks in vitro platforms comprised of human tissue constructs that will accurately assess efficacy, toxicity, and pharmacokinetics in a way that is relevant to humans and suitable for regulatory review.

Interested vendors listed so far include InVivoSciences and Cell Therapy Group.

Biomedspeak

In foreign language learning, there’s a concept called false friends — words that seem so familiar you’re tricked into thinking you know what they mean. But in reality they mean something different. For example, in German and Scandinavian languages the word “gift” doesn’t mean a present. It actually means poison.

While not as dramatic, there are false friends in biomedical lingo that you may not be aware of. The lab-on-a-chip field is especially prone to terminology-related communication barriers because it brings together a diverse crowd from all corners of the scientific, medical, engineering, business, academic, and industry worlds.  And because it’s an emerging industry, terminology is in flux.

A common principle for detecting lingo: seemingly broad terms often have narrow, specific meanings to industry insiders. In the same way that “tech industry” has come to mean software/computers/electronics (not just any type of technology), “biotech” has a specific meaning that’s more narrow than biology + technology. Here are a few examples related to the lab-on-a-chip world:

Biomedspeak: Deceptively Broad Terms

TermTo a lay person, it seems like this would mean....But the industry interpretation is actually more narrow...
Biotechnology, or biotechSeems obvious: biology + technology = any technology applied to biological or medical problems, right? Actually to an insider, "biotech" means using live micro-organisms (e.g., bacteria) to manufacture a product (typically pharmaceutical). Classic examples of biotech companies include Biogen, Genzyme, and Genentech. Medical devices are not considered biotech.
Medical devicesSeems like it would mean any device with a medical application. And many do use it this way, including the FDA. Often there's an assumption that medical devices really means therapeutic medical devices, with diagnostics considered a separate industry segment. Examples of medical device companies include Boston Scientific and Medtronic.
Molecular diagnosticsIncredibly vague term if you take it literally. Often means diagnostics based on DNA / RNA, excluding tests like immunoassays. However, some people interpret it to include tests for any protein or nucleic acid, and even include small molecules.

Bonus: An assay is just a measurement. This one is for all of you coming from non-biological backgrounds. It doesn’t fall under the common principle above, but I mention it because I’ve heard non-bio folks comment on it so often.

To make things even more confusing, a lot of these industries are beginning to collide and become interrelated. Drugs are being combined with medical devices (e.g. drug-eluting stents) and diagnostics are beginning to be linked closely with drugs to enable personalized medicine.

Do you have any examples of biomedspeak?
