Gene-silencing developer Santaris raises €20M — Denmark’s Santaris Pharma, a developer of gene-silencing drugs, raised €20 million ($30 million) (PDF) in a third financing round. Investors included Gilde Healthcare Partners, BankInvest, Novo, LD, Forbion Capital Partners, Global Life Science Venture, Sunstone Capital, Seventure, Omega, Innovation Capital and members of the Company’s board and management. Gilde contributed €7.5 million to the round.

Santaris is pursuing an “antisense” strategy for turning off particular disease-related genes using synthetic strands of nucleic acid, which bind to and deactivate the messenger RNA molecules that are crucial to gene activity. (Technically, the mRNA plays a key role in the manufacture of a gene’s protein or proteins, which in disease states are often either malformed or overproduced. The drug molecule is a complement to the mRNA’s nucleic-acid sequence, which in DNA chemistry makes it an “antisense” molecule.)

Whereas biotechs working on antisense drugs have traditionally used strands of DNA — often chemically modified to improve their durability and cell-penetrating abilities — to block gene activity, Santaris has produced what it claims is a unique RNA analogue that it calls a “locked nucleic acid.” (The company goes into detail here.) The Santaris molecule, which combines LNA and DNA, is supposed to bind RNA in three dimensions, presumably boosting its binding ability and therefore potency.

Santaris is first targeting chronic lymphocytic leukemia, and says its drug candidate has already demonstrated initial safety and efficacy in an early-stage human test. The company has several other candidates in preclinical development, as well as two other molecules it licensed to Enzon Pharmaceuticals, one of which has also begun human testing against cancer.

For a more detailed look at antisense, see our coverage of Excaliard Pharmaceuticals, a biotech that licensed a slew of technology from antisense pioneer Isis Pharmaceuticals, here.

Consumer-driven healthcare manager RedBrick Health prescribed $15M — RedBrick Health, a Minneapolis healthcare company promoting “consumer-oriented” plans that shift much of the financial responsibility for medical care to individuals, raised $15 million in a second funding round. Investors included Fidelity Ventures, Highland Capital Partners and Versant Ventures.

RedBrick aims to help companies set up consumer-directed healthcare plans, which are also known as “defined contribution” schemes in that they limit the financial exposure of employers, who simply make regular contributions to employee “health savings accounts.” These plans, obviously, put the financial onus on individuals, who pay for their own medical care out of these accounts, in contrast to traditional “defined benefit” plans in which individuals pay premiums for comprehensive health coverage. In theory, these consumer-oriented plans should hold down healthcare costs by making individuals more “responsible” users of medical care; in practice, sick patients are often in a terrible position to be good medical “consumers,” and the plans have have proven generally unpopular to boot.

That hasn’t slowed RedBrick or its backers. The company will use the funding to continue expanding its efforts to sell and manage consumer-directed healthcare plans, which RedBrick somewhat misleadingly insists on calling “consumer-owned” healthcare. (Such plans usually couple health-savings accounts with a high-deductible insurance plan.) The company recently announced deals with several new client companies, although none are exactly what you’d call high profile firms — their ranks include the Ridgeview Medical Center in the Minneapolis-St. Paul area, which is switching its employees to a RedBrick-supported plan, and Welch Allyn, a medical-device manufacturer in Skaneateles Falls, N.Y., which is doing likewise.

Cardiac Dimensions takes in $36M for heart-valve device – Cardiac Dimensions, a Kirkland, Wash., developer of heart-valve devices, raised $35.5 million in a fourth financing round. Investors included Johnson & Johnson Development, Lumira Capital, Mitsubishi UFJ Capital, West River Capital, Montgomery & Co., Frazier Healthcare Ventures, Interwest Partners, MPM Capital, and Polaris Venture Partners.

Cardiac Dimensions is working on an implantable device designed to reshape the heart’s mitral valve, which in heart-failure patients sometimes weakens and allows blood to swish backward through the heart’s chambers. We’ve covered several other startups working on mitral-valve devices, including Evalve and Cardiosolutions.

Nereus Pharma raises $45M for ocean-derived cancer drugs — San Diego’s Nereus Pharmaceuticals, a biotech that searches for cancer drugs in marine microbes, raised $45 million in a follow-on to its fourth funding round.

The company features an all-star lineup of investors, which includes BankInvest, Roche Venture Fund, Astellas Venture Management, Boston Life Science Venture Corporation, Taiwan Global Biofund, Eminent Venture Capital, HBM BioVentures, Alta Partners, Forward Ventures, Advent International, GIMV, InterWest Partners and Pacific Venture Group.

From the press release:

The proceeds from the financing will be drawn down in two tranches and used to complete Phase I and begin Phase II clinical trials for Nereus’ two drug candidates. The first compound, NPI-2358, is being evaluated for the treatment of solid tumors and lymphomas in Phase I clinical trials. It is a potent, selective tumor vascular disrupting agent (VDA), a class of compounds that represents a novel approach to disrupting the intrinsic tumor blood flow, which leads to tumor cell death. NPI-2358 has favorable preclinical characteristics, such as a longer duration of action on tumor blood flow, activity against multi-drug resistant tumor cell lines and a favorable preclinical toxicology profile. The compound is one of 200 analogues that were produced after finding activity and novel chemistry from a marine fungal extract.

Nereus’ proteasome inhibitor NPI-0052 is in Phase I trials for solid tumors, lymphomas and multiple myeloma. Preclinical studies indicate that this next generation compound may be superior to Velcade(R), with broader target inhibition, faster onset of action, higher potency, oral and intravenous availability, and activity against myeloma cells resistant to Velcade(R) (bortezomib, Millennium), Thalomid(R) (thalidomide, Celgene Corporation), Revlimid(R) (lenalidomide, Celgene Corporation) and steroid therapy. NPI-0052 was derived from a marine-obligate gram-positive actinomycete (Salinispora tropica).

Rotator-cuff specialist KFx Medical raises $10M — San Diego’s KFx Medical, a Carlsbad, Calif., developer of minimally invasive repair systems for rotator-cuff injuries, raised $10 million in a second funding round. Investors included Alloy Ventures, Charter Life Sciences, Arboretum Ventures, Montreux Equity Partners, and MB Venture Partners.

It’s pretty difficult for a non-surgeon to figure out exactly how KFx’s system works better than current medical practice, but if you’re interested in a look, check it out here.

NeuroMed Pharma drops Merck work on pain drug, raises $36M — Vancouver-based NeuroMed Pharmaceuticals, a biotech focused on new pain meds, discontinued Merck-funded work on an experimental pain drug called MK-6721. The Merck collaboration, valued at as much as $475 million, will continue.

Separately, NeuroMed has raised $36 million toward a fifth funding round, VentureWire reports (subscription required). That round isn’t yet complete, and the investors haven’t been disclosed. The funding is designed to pay for completing late-stage human trials of a separate pain drug the company recently licensed from a J&J subsidiary.

Adnexus raises $15.5M against cancer — Adnexus Therapeutics, a Waltham, Mass., biotech developing a new class of drugs against cancer and other diseases, raised $15.5 million in a third funding round. Investors included HBM BioVentures (Cayman), Atlas Venture, Flagship Ventures, Polaris Venture Partners and Venrock. The company intends to use the proceeds to further clinical development of its lead candidate, Angiocept, which is currently in early-stage trials in cancer.

Masimo IPO raises $233 million, jumps 23% on first day — Irvine, Calif.-based Masimo, a major developer of non-invasive patient monitors, priced its IPO in the middle of its predicted range of $16 to $18 per share, raising as much as $232.9 million — just shy of the quarter-million-dollar mark we discussed here. Since the offering involved a hefty chunk of shares sold by existing shareholders, however, the company can only pocket up to $55.9 million of the proceeds. Investors received the offering warmly, pushing the stock up to $20.90 yesterday, a rise of 23 percent.

Biofisica raises $2M in venture debt for wound healing — Atlanta’s Biofisica, a medical-device maker focused on wound healing, raised $2 million in debt financing from Leader Ventures. The company makes an electrical-stimulation device designed to speed the healing of wounds, and currently sells it in the United Kingdom.

Aegera acquires LymphoSign, uniting two Canadian oncology biotechs — Aegera Therapeutics, a Montreal biotech focused on cancer, acquired Toronto’s LymphoSign, another cancer-specialized biotech, for undisclosed terms. Several shareholders also made additional investments in Aegera’s previously announced third funding round.

InfuScience acquires Palmetto Infusion Services — InfuScience, a Chicago provider of drug-infusion therapy, acquired Palmetto Infusion Services of Beaufort, S.C., for an undisclosed sum.
