Immune-system specialty pharma Circassia raises £11M – Circassia, an Oxford, England biotech focused on immune-system disorders, raised £11 million ($21.8 million) in a second funding round. Investors included Goldman Sachs, Invesco Perpetual, Imperial Innovations and Lansdowne Partners.

The company is currently developing a range of allergy treatments by “retraining” the immune system not to react to allergens such as cat dander, dust mites, ragweed and grass. Circassia’s approach is to isolate short stretches of the allergy-causing proteins and expose them to the immune system’s antigen-presenting cells, attracting other cells that, though a complex biochemical dance, teach the immune system to “tolerate” the original protein.

Circassia is “preparing to complete” mid-stage trials ‘of its lead candidate, which is aimed at treating allergy to cat dander. The company says its technology should also be useful in preventing the rejection of transplanted organs.

Cancer-biomarker biotech CS-Keys takes in $6.3M – CS-Keys, an Indianapolis biotech working on protein-based “biomarkers,”, raised $6.3 million in a first funding round. Investors included Triathlon Medical Ventures, Clarian Health Ventures, Prolog Ventures and Ceres Venture Fund.

CS-Keys aims to find proteins that indicate the presence and status of tumors, and which can serve as a diagnostic for early detection or for monitoring the status of cancer patients. The company says its first product will be a pathology stain for detection of proliferating cell nuclear antigen in biopsied tumor samples. As a followup, the company intends to pursue a blood test for detecting the return of tumors in patients whose cancer has gone into remission.

Neuro-robotic device maker Myomo receives $3M – Boston’s Myomo, a “neurorobotics” company designing technology to help patients learn to regain the use of weakened or partially paralyzed limbs, raised $3 million in a second funding round, VentureWire reports. Angel investors provided the funding.

Founded in 2006, Myomo has developed a “smart” elbow brace for aiming to relearn how to move stroke-impaired arms. The brace senses electrical nerve signals in the skin’s surface, generated when patients try to move an arm, and then electromechanically moves the arm as the patient intended. The idea is to provide real-time feedback so that patients can re-educate their muscles in order to regain motor control.

The Myomo device has been studied in six patients, who demonstrated a statistically significant improvement in two measures of movement. The company has two additional studies underway in chronic and sub-acute stroke patients. The device has been cleared for hospital use, although Myomo eventually hopes to win approval for home use as well.

Myomo hopes to add another $8 million from venture capitalists by this summer, in what may either be a third round or an extension of the second. The current funding will allow the company to roll out its device to medical facilities nationwide.

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.
