[Note: I’m a little sad to announce that this will be my last life-science briefing at VentureBeat, although with luck, it won’t be the end of my time here. Starting Monday, I’ll be blogging regularly on the drug industry and healthcare over at BNET Industries, a new CNET venture, so drop by if you can. (Preparing for that move is the main reason non-briefing posts have been scarce recently.) I still hope to post here occasionally as well, since covering below-the-radar startups has been a blast, and I’m not ready to give it up quite yet.

It’s been a great year — my first VentureBeat post was on April 3, 2007 — and I want to thank Matt for the opportunity to join you here, and all our regular readers and commenters for your time and your insights. As journalists, we’re only as good as our sources and readers, and you guys have helped in countless ways to make me look much smarter than I really am. –D.P.H.]

Stent maker IDev Tech raises $25M – IDev Technologies, a Houston medical-device startup, raised $25 million in a third funding round, VentureWire reports. The company is developing a new type of stent for use in propping open the liver’s bile ducts .

The company’s existing investors, a group that includes Bay City Capital, Heron Capital, PTB Sciences and RiverVest Venture Partners, provided the funding. IDev had previously raised $24 million, according to VW.

Xytis gets $15M for brain-injury drugs – Irvine, Calif.-based Xytis, a biotech focused on disorders of the central nervous system, raised $15 million in an extension of its second funding round, VentureWire reports. Its backers included Atlas Venture, CDC Innovation, Sanderling Ventures and Ventech.

The company says it was founded in 2005 from the merger of Xytis Pharmaceuticals and Remergent. (Sounds more to me like Xytis swallowed Remergent, but they’re free to describe it however they’d like.) Its lead drug candidate, XY2405, blocks a cellular protein called the Bradykinin B2 receptor, a signaling molecule thought to promote inflammation.

Xytis is testing the drug as a potential treatment for traumatic brain injury; the molecule is currently in mid-stage, phase II trials. The company is also testing an antidepressant in early-stage trials.

Xytis raised half the money last August, then received the second $7.5 million in April, the company told VentureWire. It has previously raised $24.5 million in its current incarnation, and its “predecessor companies” pulled in $6.5 million.

Diagnostic maker Iris Biotech plans to go public, launch breast-cancer test – Santa Clara, Calif.-based Iris Biotechnologies, a developer of molecular diagnostic tests, is preparing to go public, VentureWire reports. The company plans a small offering on the OTC Bulletin Board — if I’m reading its latest SEC filing correctly, its existing shareholders will raise about $1.1 million, with no proceeds headed to the company  — and hopes to launch a breast-cancer test later this year.

Iris plans to use chips to measure gene activity in breast cancer, with the hope of predicting the odds that a surgically removed tumor will recur and, eventually, helping patients and doctors customize cancer treatment from an early stage. The company claims that it will be competitive with Genomic Health and Agendia, two companies with similar tests for predicting breast-cancer recurrence.

There’s something a little odd about Iris’ disclosures in the SEC forms, though. Iris doesn’t describe its technology, the genes it will test or how it settled on them in any detail, and spends almost as much time talking about its database of patient information and related computer technology as it does about its tests. While it may consider some or all of that information a trade secret — and disclosure requirements may well be looser for such a small offering — it’s still kind of unusual for a startup to ask outside investors to put up their money essentially on faith.

AGI Dermatics takes in $5M for skincare products – Freeport, N.Y.-based AGI Dermatics, a startup concentrated on skincare products, raised $5 million in a new funding round. Investors included Trevi Health Ventures and Spring Mountain Capital.

AGI makes cosmetic ingredients and is working on developing topical pharmaceutical lotions as well. Its leading drug candidate is called T4N5 Liposome Lotion, which AGI says includes a DNA-repair enzyme intended to repair ultraviolet damage to the skin. The company is currently testing the product as a preventive treatment for skin cancer.

Germany’s Noxxon gets €1M grant for aptamer drugs — Noxxon, a German biotech aiming to make drugs from nucleic-acid snippets called aptamers, received a grant from Germany’s Federal Ministry of Education and Research. The €1 million ($1.6 million) grant is intended to support Noxxon’s drug-discovery program, which we covered at greater length last May.

Myconostica raises £3.9M for fungal diagostics – Myconostica, a U.K. biotech that spun out of the University of Manchester, raised £3.9 million ($7.7 million) in a third funding round, GenomeWeb reports. Investors included Amphion Innovations, Nexus Medical Partners, and Innoven Partenaires.

The company is working on rapid diagnostic tests for life-threatening fungal infections. Its first product is a test for several types of fungal infection that is nearing approval in Europe, and which Myconostica thinks could receive U.S. approval by the fourth quarter.

Another one bites the dust.

The saga of Precision Therapeutics, a Pittsburgh biotech developing what struck me last August as a particularly crude type of cancer-chemotherapy diagnostic, continues apace. In a tersely worded press release, the special-purpose acquisition company Oracle Healthcare Acquisition said it has terminated its planned merger with Precision. The release blamed “currently prevailing market conditions” for the decision, which carries some fairly ominous consequences for both sides.

Oracle’s plight is fairly simple: The blank-check company will now dissolve itself and return the money it raised, minus expenses, to investors. For Precision, however, the outlook is much starker. The merger would not only have taken the company public, it would have left Precision with $120 million in cash, ample resources to bolster sales of its ChemoFx test and to develop new potential products.

Now, after getting jilted at the altar by Oracle and withdrawing its IPO, the startup is most likely almost out of cash. As of September 30, Precision had only $15.6 million in cash and cash equivalents and a working-capital deficit of $1.1 million against debts of $17 million — plus a burn rate of roughly $3 million a quarter. Those numbers don’t look good by any measure

The first real sign the merger was in trouble came just about two weeks ago, when Oracle and Precision effectively cut the overall size of the deal by 15 percent — never a good sign. Oracle’s decision to walk away remains murky to me given the complexity of the deal, and external market events might have somehow triggered provisions that made the acquisition untenable. But I can’t help wondering if the buyers may have simply concluded that Precision’s prospects weren’t at all what they once thought.

Precision Thera merger with “blank check” Oracle Healthcare collapses – Another one bites the dust.

Sleep Solutions takes in $21M for sleep-apnea diagnostics – Sleep Solutions, a Pasadena, Md., developer of diagnostic devices for sleep apnea, raised $20.5 million in a new funding round. Investors included TPG Biotechnology, MedVenture Associates, Emergent Ventures and Lava Ventures.

Sleep Solutions has developed a home-use diagnostic device for identifying sleep apnea, which are breathing difficulties during sleep. Diagnosing apnea has traditionally required patients to spend the night in a sleep laboratory. Left untreated, apnea can increase the risk of more serious problems, including stroke and heart attack.

Trevena takes in $24M for drugs targeting G-proteins – Trevena (no Web site), a Berwyn, Penn., biotech focused on a new area of drug discovery, raised $24 million in a first funding round. Investors included Alta Partners, Healthcare Ventures, New Enterprise Associates and Polaris Venture Partners.

Like many biotechs, Trevena plans to develop drugs that attack a particular biological mechanism rather than any particular disease. In this case, the company is targeting a class of proteins known as G-protein coupled receptors, or GPCR, which according to the company are affected by close to 40 percent of all drugs on the market today. The company didn’t describe its plans in any detail.

• InfraReDx takes $17M for arterial-plaque detection (VentureWire)
• Life-sciences fund Longitude Capital raises $95M (VentureWire)

InfraReDx takes $17M for arterial-plaque detection – InfraReDx, a Burlington, Mass., developer of diagonstic systems that detect arterial plaque, raised $17 million in a third funding round, VentureWire reports. Sanderling Ventures led the round, joined by new and previous individual investors.

InfraReDx previously planned to raise up to $40 million in order to support expected commercialization of its near-infrared device, which can identify buildups of arterial plaque that can rupture and lead to heart attacks (see our coverage). The test, however, requires a minimally invasive procedure in which the device is threaded into a patient’s circulatory system, making the InfraReDx device primarily useful for preventing second heart attacks in patients who are being treated for their first.

The company submitted its device for FDA approval in October, and is planning on a limited rollout if the device is cleared this quarter, as InfraReDx expects.

Life-sciences fund Longitude Capital raises $95M – Menlo Park, Calif.-based Longitude Partners, a spinout of Pequot Ventures, raised $95 million of an anticipated $325 million first fund, VentureWire reports. The fund will invest in biotech, medical-device and drug-development startups.

(NOTE: This item originally appeared in today’s daily briefing. It’s been expanded and rewritten here.)

DNA-based diagnostics face a fundamental, though hardly insuperable, obstacle: When you’re looking for a rare mutation or other identifying sequence of DNA “letters” (technically known as bases or nucleotides), there are rarely enough matching DNA molecules in your average blood or tissue sample for today’s technology to detect. So many such tests first require technicians to “amplify” DNA in the sample, usually by a process called polymerase chain reaction, or PCR, which essentially “clones” DNA molecules by the millions — an extremely useful process that is nevertheless time-consuming and which requires expensive, specialized equipment.

One company claiming to have built a better DNA mousetrap is Adnavance Technologies, a Vancouver, Canada, startup with an intriguing nanotech method for detecting small quantities of DNA. Adnavance just raised C$3.7 million ($3.7 million) in a second round of funding, with investors including the Working Opportunity Fund, JovInvestment Management and the Business Development Bank of Canada.

As you can tell from its older logo, reproduced to the left, Adnavance chose its name in part to emphasize its focus on DNA. The company, founded in 2002, is developing tests based on a molecular trick that makes selected strands of DNA conduct electricity, making it possible to detect their presence using a microarray of tiny electrodes.

The basic idea is this: Using specific chemical conditions, Adnavance says it’s possible to force metallic ions between the double strands of DNA, where they displace the protons that usually help hold the helical molecules together. The metallic ions then serve much the same purpose as the central wire in a coaxial cable by freely conducting electricity, giving the DNA molecule as a whole an electrical property that can be measured directly.

Adnavance’s method starts by binding “capture” strands of DNA — that is, stretches that will bind to whatever mutated gene or viral sequence someone is looking for — to a gold electrode and “dehybridizing” them into their single-stranded forms. Once introduced to serum from a blood sample, say, those capture strands stick to matching DNA from the sample and resume their double-stranded shape. The system measures the conductivity of the bound DNA molecules, then introduces the metal ions to the solution, which in theory only integrate into capture probes that have bound perfectly to their targets — thus presumably eliminating mismatches. Measuring the difference in conductivity of the metallized strands compared to their predecessors yields a signal that the company says can detect as few as 500 matching DNA molecules. (By contrast, similar existing tests may require anywhere from 5,000 to 1 million target sequences to yield a detectable signal.)

The company’s first product candidate is a test for antibiotic-resistant staphylococcus, which it believes it can get onto the market by 2010. Adnavance believes its test will be simple enough for use in as many as 30,000 clinical laboratories that aren’t currently licensed to carry out existing DNA-based tests.

Oddly enough, Adnavance’s latest funding round is smaller than its first $3.9 million funding in 2005. That’s a little unusual for a company at this stage, and raises the natural question of whether it’s been forced to take a “down round” with a lower valuation than it previously held. An Adnavance representative, however, says that in 2005, the company actually included two other lines of business — focused on hydrogen fuel cells and DNA vaccines — that were spun out prior to the current funding round. So by that logic, the share of funding devoted to the DNA-diagnostic work has presumably risen. I should note, though, that the company’s lengthy release at the time was mostly devoted to its diagnostic work, and mentions the fuel-cell research in just two sentences at the end (and the vaccine not at all).

Adnavance has also named a new CEO, V. Randy White, who previously served as chief executive at Nanogen and Xenomics.

Adnavance pulls in C$3.7M for molecular diagnostics, names new CEO – Adnavance Technologies, a biotech developing molecular diagnostics, raised C$3.7 million ($3.7 million) in a second round of funding. Investors included the Working Opportunity Fund, JovInvestment Management and the Business Development Bank.

Adnavance — judging from its logo, the name is intended to imply the biotech’s focus on DNA-related technology — was founded in 2002 and is developing diagnostics based on a molecular trick that allows the company to substitute metallic atoms into ordinary DNA under specific conditions. By using a microarray of tiny electrodes, Adnavance says it should be possible to detect particular DNA sequences without “amplifying” the molecules thousands or millions of times, a time-consuming step that requires expensive capital equipment. The company’s first product candidate is a test for antibiotic-resistant staphylococcus, which it believes it can get onto the market by 2010.

Oddly enough, Adnavance’s latest funding round is smaller than a $3.9 million funding in 2005 — presumably the company’s first — that’s described here. That’s a little unusual for a company at this stage, and raises the natural question of whether it’s been forced to take a “down round” with a lower valuation than it previously held. There’s no easy way to answer that question at the moment, as the company’s PR representative didn’t respond to a question on the subject.

Separately, Adnavance named Randy White, the former CEO of both Nanogen and Xenomics, as its new CEO.

“Personalized medicine” co. Proprius sells to Cypress Bio for up to $75M – Proprius Pharmaceuticals, a San Diego diagnostics maker, sold itself to publicly traded Cypress Bioscience for up to $75 million in cash. The company’s release is here.

Cypress will pay $37.5 million up front, and another $37.5 million to Proprius shareholders as milestone payments. Proprius licenses and develops drugs and diagnostics for various forms or arthritis. Its most immediate product candidates include tests that aim to predict whether certain individuals will develop rheumatoid arthritis and that monitor patients’ response to methotrexate, a common treatment for RA.

Vaccinex raises $25M in wake of GSK deal for antibody drugs – Rochester, N.Y.-based Vaccinex, a developer of antibody drugs, raised $25 million in an add-on to its second funding round, VentureWire reports. Investors included Teva Pharmaceutical Industries, Pan Atlantic Bank and Trust and individual investors.

Earlier this month, Vaccinex and its partner EUSA Pharma licensed a Vaccinex antibody to GlaxoSmithKline for up to $44 million plus royalties. Vaccinex and EUSA will split any profits from GSK’s potential sales of the drug.

Compact ultrasound maker Zonare Medical raises $30M – Zonare Medical Systems, a Mountain View, Calif., maker of ultrasound-imaging systems, raised $30 million in a recent seventh funding round, VentureWire reports. Existing investors provided the funding, a group that includes Frazier Healthcare Ventures, 3i Group, Mosaix Ventures, CB Health Ventures, Draper Fisher Jurvestson, Ascension Health Ventures, Kaiser Permanente Ventures, Earlybird, Saints Capital, Merrill Lynch Venture Capital and Texas Instruments.

The company said the funding should set it on the road to profitability and eventually to a hope-for IPO. Zonare makes compact ultrasound systems that can be used in sonography and for a variety of other medical diagnostic purposes.

TherOx raises $30M for hypersaturated-oxygen devices – TherOx, an Irvine, Calif., maker of oxygenation devices for treating heart attacks, raised $30 million in a tenth funding round, peHUB reports. Investors included Kleiner Perkins, Integral Capital Partners and New Science Ventures.

The startup makes devices that supersaturate blood with oxygen, then infuse that blood into areas of the heart at risk of damage from oxygen starvation due to a heart attack. TherOx has now raised over $120 million in venture funding.

Accumetrics, antiplatelet-drug diagnostic maker, raises $29M – San Diego’s Accumetrics, a maker of diagnostics that measure patient response to anti-platelet drugs, raised $28.8 million in a fourth round of funding. Investors included Arnerich Massena & Associates, BBT Fund, Essex Woodland Health Ventures, RiverVest, PTV Sciences, KB Partners and Kaiser Permanente Ventures.

The startup makes a system that measures how well individuals are reacting to treatment with anti-platelet drugs, which are used to prevent or help dislodge major blood clots. Since patient response can vary widely, often as a result of genetic factors (see our coverage of this sort of “personalized medicine” here), such monitoring can help doctors avoid dangerous overdoses or to switch unresponsive patients to higher doses or different drugs as necessary.
