[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.

ProGenTech takes in $21M for DNA purification systems – ProGenTech, an “East-West” tool and equipment maker, raised $21 million in a third funding round. Investors included Bay City Capital of San Francisco and DT Capital of Shanghai.

ProGenTech makes purification systems that isolate DNA from blood or other biological samples for processing and analysis. The startup is based in Shanghai and Emeryville, Calif.

Diabetes-drug maker Phenomix raises $18M while seeking IPO – Phenomix, a San Diego biotech developing new diabetes drugs, raised a total of $73.3 million in its third funding round, according to a recent amendment to its IPO filing. VentureWire reports that the startup had raised $55 million as of March 2007, suggesting the company pulled in an additional $18.3 million since then.

Phenomix claims to be a “fast follower” in drug development, a company that aims to create better versions of drugs that take aim at biological mechanisms already proven to work by earlier drugs. Its leading drug candidate is an inhibitor of dipeptidyl peptidase-4, or DPP-4, an enzyme that plays a role in insulin production, for use in type 2 diabetes. The company is looking to raise $86.3 million in its IPO.

Genome-tool maker BioTrove gets $23M in preparation for IPO – BioTrove, a Woburn, Mass., biomedical equipment maker, raised $22.7 million in a third funding round just prior to filing for an IPO, according to its SEC registration statement. The funding was first reported by VentureWire.

The company makes tools and systems for DNA analysis and drug screening. It filed yesterday to raise $75 million in its initial offering. BioTrove’s backers in the latest fundraising included Catalyst Health and Technology Partners, CB Health Ventures, Vox Equity Partners, and Fletcher Spaght Ventures.

• EKR Therapeutics takes in $50M plus $95M in debt for pain, heart drugs (release)
• Wright Medical acquires Berkeley’s Inbone Tech for $24M (release)
• Argolyn Bioscience names Nixon Ellis as CEO (release)

BrainCells raises $30M for neuroregeneration drugs – San Diego’s BrainCells, a startup focused on drugs intended to stimulate the growth of new neurons, raised $30 million in a second funding round. Investors included MedImmune Ventures, Bay City Capital, Oxford Bioscience Partners, Technology Partners, Pappas Ventures and Neuro Ventures.

BrainCells set out several years ago to discover drugs that stimulate neuron growth, following pioneering discoveries at the Salk Institute that revealed mechanisms by which the brain itself regrows its primary cells under certain circumstances. The startup, which raised $17.7 million in a 2004 first round, has been screening experimental compounds against neural stem cells to identify ones that had the previously overlooked property of promoting the growth of new brain cells.

The company’s lead drug candidate, BCI-540, which it licensed from Mitsubishi Pharma, will soon be mid-stage, phase II trials as a potential treatment for depression and anxiety disorder. (Mitsubishi had previously tested as a possible Alzheimer’s therapy, so it’s already been taken by 700 patients and is considered safe.) A follow-up compound, also licensed from a Japanese company — Taisho Pharmaceutical — remains in animal testing at the moment.

EKR Therapeutics takes in $50M plus $95M in debt for pain, heart drugs – Cedar Knolls, N.J., specialty pharma EKR Therapeutics raised $50 million in a fourth funding round that also included $95 million in debt. Investors in the equity round included MPM Capital, LLR Partners, Quaker BioVentures, the Garden State Life Sciences Venture Fund, NewSpring Capital and ESP Equity Partners. GE Healthcare Financial Services provided the debt financing.

EKR, like most specialty pharmas, acquires or licenses cast-off drugs from other companies, usually in hopes of finding new uses for them. Although the release doesn’t say so specifically, this funding will likely cover the company’s recent purchase of several drugs from the rapidly disintegrating PDL BioPharma; last month, EKR said it had raised an undisclosed amount of funding for that deal, in which it agreed to pay $85 million up front and another $85 million in potential milestone payments.

The company also has the distinction of using that deal to “re-acquire” several drugs that an earlier incarnation known as ESP Pharmaceuticals handed to PDL in a 2005 acquisition, an interesting turn of events we covered here.

Q Thera takes in $15M for neural stem-cell treatments – Q Therapeutics, a Salt Lake City biotech working on neural stem-cell treatments for neurological conditions, has received the first portion of a $15 million second funding round. Investors in the round included vSpring Capital, Invitrogen, Epic Ventures, Toucan Capital, University of Utah Research Foundation, Salt Lake Life Science Angels and Q management.

Q is taking aim at diseases such as multiple sclerosis and cerebral palsy that result when the protective myelin sheath that protects nerve fibers and the spinal cord deteriorates, often for little-understood reasons. The company is developing neural stem cells that can produce new glial cells, which in theory should be able to regenerate the damaged myelin. (Irritatingly enough, the company insists on calling its product “Q cells.”) The company aims to begin clinical trials in transeverse myelitis, a paralyzing form of MS, next year.

Stroke clotbuster Concentric Medical withdraws IPO – Concentric Medical, a Mountain View, Calif., developer of medical devices for removing stroke-causing blood clots, withdrew its proposed IPO. The company becomes the eighth life-science startup to abandon an IPO this year.

Concentric, of course, cited “unfavorable market conditions” as the reason for its withdrawal. The device maker, which is still unprofitable, reported working capital and cash and short-term investments of $20.3 million at the end of June and has been burning cash at a rate of about $7 million a year, so it’s not necessarily in dire straits. Concentric, in fact, today announced it had arranged a $15 million line of credit with Horizon Technology Finance, giving it an additional cushion.

The company makes and sells a catheter-based device that can be snaked through a patient’s blood vessels to the brain in order to physically “grab” and remove stroke-causing blood clots. Although Concentric won approval for the device in 2004, sales have grown more modestly — in part, perhaps, because Concentric hasn’t undertaken the clinical studies necessary to demonstrate the usefulness of its technique compared to other treatments, and has no plans to do so. (The company listed this point as a risk factor in its SEC filings.) What’s more, the Concentric device can sometimes damage blood vessels in the brain; in one of two studies, almost ten percent of patients suffered a cranial hemorrhage.

Our previous coverage of the company is here.

Avera recaps with $9M to relaunch human tests of GI drug – Avera Pharmaceuticals, a San Diego specialty pharma developing drugs against a variety of conditions, recapitalized with a $9 million “first” funding round, VentureWire reports. Such a recap usually amounts to a restart for a company, which in this case was prompted by a halted clinical trial of a drug for irritable bowel syndrome and overactive bladder.

Investors in the recap included all participants in the company’s previous funding round: Aisling Capital, SV Life Sciences, Aberdare Ventures, BioAsia Investments, H.I.G. Ventures, Montreux Equity Partners, Bay City Capital, BTG PLC, Frazier Healthcare Ventures, InterWest Partners, St. Paul Venture Capital and Windamere Venture Partners. The company declined to provide a valuation to VentureWire, but it’s almost certainly suffered a “down round,” or it wouldn’t be recapitalizing.

Avera shut down mid-stage trials of its drug, known as AV608, last year after animal testing turned up potential toxicity issues. The company has since redesigned the drug to eliminate a compound it called a “non-active metabolite,” and hopes to resume studies later this year. Avera had raised more than $72 million prior to the recap.

Tacere Therapeutics strikes RNAi deal with Pfizer for up to $145M — San Jose, Calif.-based Tacere Pharmaceuticals, a biotech developing new drugs based on the gene-silencing technique known as RNA interference, struck a partnership deal with Pfizer that could be worth up to $145 million. The company’s release is here.

The deal involves Tacere’s leading drug candidate for hepatitis C. Known as TT-033, the drug consists of short stretches of RNA designed to trigger cellular mechanisms that shut down the activity of specific genes — an exciting but so far still unproven approach. In this case, TT-033 aims to shut down three separate parts of the hepatitis C genome, theoretically not only inactivating the virus, but also preventing the development of resistant viral strains.

Tacere is already co-developing TT-033 with Oncolys BioPharma of Japan, and in fact has deep Japanese roots, as the company also received its founding capital from Hokkaido Venture Capital of Sapporo, Japan. (Our coverage of the Oncolys deal is here.) The Pfizer deal appears to be complementary to Tacere’s previous agreement, as the Big Pharma will receive worldwide rights to TT-033 excluding Asian nations. Pfizer will fund all future development of the drug, and will make milestone payments to Tacere as development proceeds. TT-033 has not yet entered human testing.

Surgical-device maker Aragon Surgical receives $25M — Aragon Surgical, a Palo Alto, Calif., developer of surgical instruments, raised $25 million in a second funding round. Investors included Bay City Capital, Integral Capital Partners, Delphi Ventures and Onset Ventures.

Founded in 2005, Aragon develops tools and instruments intended to speed surgical procedures and to improve their safety. The company is working on two major classes of devices — “electrosurgical” instruments, which use electric current to stop bleeding, remove growths and cut tissue, and tools that improve the speed and safety of minimally invasive surgeries known as laparoscopies. Last September, Aragon launched its first product, the LapCap, which guides a needle used to inflate a patient’s abdomen with gas in order to reduce the risk of inaccurate placement and injury.

Benvenue Medical raises $15M for spine-repair devices — Mountain View, Calif.-based Benvenue Medical, a developer of minimally invasive devices for spine surgery, raised $15 million in a second funding round. Investors included Three Arch Partners, Versant Ventures and De Novo Ventures.

Benvenue is developing spinal implants designed for the treatment of spinal compression fractures and degenerative disk disease via spinal fusion. The company’s Web site is a stub, and it doesn’t seem to have described its technology in much detail yet.

Stem-cell biotech BioE seeks $3.5M — St. Paul, Minn.-based BioE, a provider of stem-cell products for the drug and biotech industries, hopes to raise $3.5 million in a first funding round, VentureWire reports (subscription required). The company has so far raised $30 million from angel investors, and disclosed its plans in a regulatory filing. The funds will allow the company to commercialize lines of “multi-lineage” progenitor stem cells and a system for processing and freezing of umbilical-cord blood stem cells.

Inovise raises $3.4M for heart diagnostics — Inovise Medical, a Portland, Ore., developer of cardiac diagnostics, raised $3.4 million in convertible notes, VentureWire reports, citing a regulatory filing. The company is in the midst of fundraising for a sixth financing round. Inovise makes a non-invasive cardiac monitoring system called Audicor that records and analyzes sounds emitted by a beating heart.

Fairway Medical pockets $1M for medical devices, aims for $10M — Fairway Medical Technologies, a Houston incubator that develops a variety of medical devices, raised $1 million from angel investors and is looking to draw another $5 million to $10 million in a first institutional round later this year, VentureWire reports. Founded in 1992, Fairway Medical in-licenses medical devices and ushers them through the development process.

Cancer-drug biotech Genspera pulls in $650K, looks for $5M more — Santa Monica, Calif.-based Genspera, a biotech focused on cancer drugs, raised $650,000 in a seed round and aims to close another $5 million in funding later this quarter, VentureWire reports. The company plans to list its shares on the Nasdaq over-the-counter bulletin board following the financing. Genspera is working on cancer drugs using technology licensed from Johns Hopkins University.

E-trolZ looks for $400K for electrophysiology devices — North Andover, Mass.-based E-trolZ, a developer of electrophysiology measurement devices, raised $400,000 in a follow-on to its first $1.2 million funding round, VentureWire reports. The company is developing components that measure various physiological signals and which can be integrated into other medical devices.

Featured companies: Aveo Pharmaceuticals, Aviir, deltaDot, Origen Therapeutics

Heart-diagnostic maker Aviir raises $11.3M — Palo Alto, Calif.-based Aviir, a biotech developing cardiovascular diagnostics based on Stanford research, raised $11.3 million of an expected $25 million second funding round, PE Hub reports. The news is presumably from one of those paper-based SEC filings that are supposed to be digitized before long.

Investors include Bay City Capital, Aberdare Ventures and New Leaf Ventures. Aviir hasn’t said much about its technology beyond the fact that its tests are designed to provide “accurate diagnosis and prognosis” of heart disease and that it expects to reach the market next year. That’s ridiculously fast for anything that needs to move through clinical trials, so chances are good that Aviir is aiming for some sort of “home-brew” strategy in which it will conduct the tests itself instead of selling kits and reagents to clinical laboratories around the country. Home-brew tests are regulated less strictly by the FDA.

DeltaDot, biological tool maker, raises £3M — The London maker of tools for identifying and separating biomolecules drew in £3 million ($6.1 million) (PDF link) from investors in a fourth funding round, bringing the total raised in that round to £6 million. Investors included FF&P Private Equity, Imperial Innovations, NPI Ventures, Sitka Health Fund VCT and London Technology Fund.

DeltaDot, which spun out of the Imperial College of Science, Medicine and Technology, uses technologies from high-energy physics to measure the ultraviolet-light absorption of molecules and then applies signal-processing algorithms to identify them.

Aveo Pharma raises $5M in broader deal with OSI Pharma — Cambridge, Mass.-based Aveo Pharmaceuticals, a biotech developing targeted cancer drugs, raised $5 million in equity and received another $10 million in cash as part of a broader development partnership with publicly traded OSI Pharmaceuticals. The deal will also include payments for future milestones and royalties, if any, although the companies didn’t estimate their potential value.

The alliance is aimed at developing drugs that target a cellular process known as “epithelial-mesenchymal transition,” a natural stage of cellular development mimicked by tumor cells as they spread, or metastasize, throughout the body. See our previous coverage of Aveo here.

Origen receives $2M grant for chicken-based antibodies — Burlingame, Calif.-based Origen Therapeutics, a company focused on developing biotech products from genetically engineered chickens, received a $2 million grant from the National Institute of Standards and Technology. The funding is intended to spur development of human polyclonal antibodies — which attack a variety of different protein targets instead of a single one, the way monoclonal antibodies do — that can be produced by chickens and deposited in eggs for harvesting. The first goal of the program will be to develop therapies for antibiotic-resistant hospital infections, which represent a growing threat to patients.

From the Origen press release:

Most antibody therapeutics today, such as the cancer treatments Avastin® and Herceptin® and the anti-infective Synagis®, are monoclonal antibodies that attack a single antigen target on a cell or viral surface. In contrast, when the human immune system produces antibodies against disease, it makes polyclonal antibodies capable of recognizing and attacking different antigens on the same cell, enabling that disease target to be simultaneously attacked at many different points. Thus the ability to produce fully human polyclonal antibodies on a commercial scale for use as therapeutics could take antibody-based therapies to a new level of efficacy by more closely mimicking the full potential of the natural human immune response. Until now, the production of safe and effective polyclonal antibody treatments has been hampered by the lack of an appropriate system for the development and production of such antibodies.

Featured companies: Agendia, EndoGastric Solutions, FlowCo, Gentris, MedManage Systems, ParagonDx, Presidio Pharmaceuticals, Xoova

Presidio Pharma raises $26M for viral treatments — San Francisco’s Presidio Pharmaceuticals, a biotech developing new antiviral drugs, raised $26 million in a second funding round. Investors included Panorama Capital, Baker Brothers Investments, Bay City Capital, Ventures West Capital, Nexus Medical Partners, Sagamore Bioventures, George Rathmann Fund and Peninsula Overview Partners.

Presidio’s lead drug candidates take aim at HIV, hepatitis C and other viral infections. None of its drugs have entered human tests yet.

EndoGastric Solutions pulls in $30M for “transoral” surgeries — Redmond, Wash.-based EndoGastric Solutions, a medical-device maker developing products for incision-free gastrointestinal surgery, raised $30 million in a fourth funding round. Investors included DeNovo Ventures, Chicago Growth Partners, MPM Capital, Advanced Technology Ventures, Foundation Medical Partners, and Oakwood Medical Investors.

In March, EndoGastric received FDA clearance for a device it calls the StomaphyX, a disposable surgical instrument that can be passed into the stomach or the intestines via a patient’s mouth. Although EndoGastric isn’t too clear on exactly what the StomaphyX is for — the company says it’s for use in “endoluminal transoral tissue approximation and ligation” — the device appears to be a sort of staple gun that can fasten together parts of the stomach or intestines. EndoGastric says the device can be used to treat gastroesophageal reflux disease, and its Web site appears to suggest that it can also perform bariatric surgery from inside the stomach as a treatment for obesity.

Agendia gets $34M for gene-based diagnostics — Amsterdam-based Agendia, a developer of gene-based diagnostic tests for cancer, raised $34 million (€25 million) in a fourth funding round. Investors included ING, Van Herk Biotech, Gilde Healthcare Partners and Global Life Science Ventures.

Agendia, founded in 2003, sells diagnostic tests that assess the “activity level” of various genes in tumor tissue, a technique that allows it to predict whether, for instance, a woman has a high or a low risk of seeing her breast cancer return. That test, sold under the brand name MammaPrint, was approved in the U.S. in February. Agendia has developed similar tests for identifying unknown cancers and for assessing the prognosis of colon cancer.

MedManage Systems, a drug-sampling service provider, receives $5M — MedManage Systems, a Bothell, Wash., company that helps drug manufacturers push free samples into the hands of doctors in order to “build brands,” raised $5 million of a planned $10 million financing, PE Hub reports, citing a regulatory filing. Investors include Lilly Ventures, Prism VentureWorks, QuestMark Partners and Versant Ventures.

At heart, MedManage’s business seems to be a consulting service that uses a mix of technology, data analysis and old-fashioned legwork make it easy for physicians to hand out free drug samples, which the MedManage site calls “a proven marketing strategy” for “influenc[ing] physician prescribing behavior.”

The company’s Web site is larded up with all manner of marketing buzzwords, but it’s actually fascinating to read through. That’s because most folks in the pharmaceutical industry would never admit that drug samples are part of a sophisticated marketing program aimed at getting doctors used to particular brands and patients to request them by name. (Large drug companies would prefer you to believe that they give away free drugs out of the kindness of their heart and sympathy for the people who can’t afford their products.) MedManage, however, makes no bones about using samples to push particular drugs. So for a peek behind the curtain, check out MedManage’s description of what it calls its “OmniSample Solution” — it’s very illuminating.

Xoova raises $2.5M for medical social-networking — Santa Monica, Calif.-based Xoova, a social network for doctors and patients, has raised $2.5 million in a first funding round last year, VentureWire reports (subscription required). Spark Capital Partners provided the funding.

Xoova allows physicians to post profiles of themselves online, much the way Facebook and similar services do for the general population. Xoova CEO Tommy McGloin estimates that 20,000 doctors have already done so, a number he hopes will grow to 100,000 by the time he begins raising an expected $5 million round next year.

Consumers can search the doctor profiles and, in some cases, can make appointments online if the doctor has signed up for a free Xoova service. McGloin said the company intends to roll out new features in coming months, although the one cited by VentureWire — allowing patients to both book and cancel appointments online — sounds awfully mundane.

Cardiac-device maker FlowCo raises $250K — FlowCo, an Indianapolis medical-device developer, raised $250,000 in a seed financing. BioCrossroads provided the funding. FlowCo, which doesn’t have a Web site, is working on a new catheter for deploying arterial stents, the wire-mesh devices that prop open clogged arteries, more accurately.

ParagonDx acquires Gentris unit for early diagnostics — ParagonDx, apparently a newly formed Morrisville, N.C., biotech firm focused on molecular diagnostics, said it acquired the Gentris Diagnostics unit of Gentris, a pharmacogenomics firm also based in Morrisville. Financial terms of the deal weren’t disclosed.

It’s not immediately clear exactly what this transaction means — I’m assuming ParagonDx was essentially spun out of Gentris, but the release isn’t terribly clear on that point. There are also some other oddities, such as the fact that as of this moment, the ParagonDx URL redirects to the Gentris site. It’s entirely possible that they’re just working out merger-day glitches, but it’s also possible something else weird is going on.

UPDATE (3:10pm PT): Added items on MedManage Systems, Xoova, FlowCo and ParagonDx/Gentris.

Vivaldi Biosciences, a San Francisco developer of flu vaccines and therapies, raised $2 million in a first round of funding, VentureWire reports (subscription required). The initial funding was raised through Bay City Capital.

Vivaldi is reportedly working on live attenuated vaccines for influenza and a potential drug for treating the flu. The company plans to push some of its candidates into the clinic by the middle of next year, and plans to focus on the elderly, who are particularly susceptible to the flu.

Conatus Pharmaceuticals, a San Diego developer of drugs for inflammation and liver disease, closed a $22 million private placement that brings its first round of funding to $27.5 million. Investors included Aberdare Ventures, Advent Venture Partners, Bay City Capital, and Gilde Healthcare Partners.

Conatus was founded by former executives of Idun Pharmaceuticals in mid-2005 after Pfizer acquired their company. The funding will support mid-stage clinical trials of its lead compound, CTS-1027, for liver disease. The first trial, in hepatitis C patients, is expected to begin by the end of this year. Conatus licensed CTS-1027 from Roche last November.
