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.

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.

TODAY’S HEADLINES:

• Ulthera receives $23M for cosmetic ultrasound devices (release)
• Senexis raises £2.9M for Alzheimer’s drugs (PDF release)
• Elixir Pharma postpones IPO (IPO Home)
• Cancer Therapeutics names Randall Riggs as CEO (release)

Ulthera receives $23M for cosmetic ultrasound devices — Ulthera, a Mesa, Ariz., startup developing ultrasound systems for cosmetic procedures, raised $22.5 million in a second funding round. Investors included New Enterprise Associates and 3i.

Ulthera, whose Web site is still a stub, aims to use its ultrasound devices for face lifts and “skin rejuvenation.” The company says the ultrasound can penetrate and remove — “microabrades,” in its terminology — skin tissue that is several layers deep without disturbing the surface, or epidemis. Deeper treatment supposedly triggers a “natural healing effect,” which Ulthera’s CEO claims will lead to a “gradual lifting and tightening of skin tissue in and around the face.”

The product can produce ultrasound images of the area to be treated as well. Ulthera has regulatory clearance to sell its device in Europe and expects FDA approval soon as well. The company will use the funds it raised for global commercialization, product development and to conduct additional trials to expand the use of its technology.

Senexis raises £2.9M for Alzheimer’s drugs — Senexis, a Cambridge, U.K., biotech working on drugs for Alzheimer’s disease and other conditions related to aging, received £2.9 million ($5.7 million) from the Wellcome Trust. The funding came from the Wellcome’s “Seeding Drug Discovery” program, and and augments £700,000 Senexis raised last year from BTG, a London specialty pharma. BTG and the Wellcome had previously invested £2.4 million in Senexis.

The company is developing small-molecule drugs intended to prevent the misfolding of amyloid proteins, which clump together in plaques around nerve fibers. Many scientists believe that these amyloid plaques cause inflammation that ultimately kills nerve and brain cells in Alzheimer’s patients, although dissenters still argue that plaques may be a distraction or even a defensive reaction to the disease. At this point, no one can say for certain exactly what causes the disease.

Still, most Alzheimer’s drugs now under development target the clumping amyloid proteins, and Senexis is no exception. One of its two lead candidates is a small molecule designed to inhibit the misfolding and aggregation of amyloid proteins in Alzheimer’s patients. The other is intended to tamp down brain inflammation. Both are still in animal testing. Senexis also hopes to treat diabetes by inhibiting aggregation of an amyloid protein that the company appears not to have identified.

Elixir Pharma postpones IPO — Elixir Pharmaceuticals, a Cambridge, Mass., biotech focused on anti-aging and obesity drugs, postponed its IPO. The company had most recently planned to raise as much as $92 million in its offering.

It’s not entirely clear why Elixir, which I figured would follow in the footsteps of Sirtris Pharmaceuticals‘ successful IPO (our coverage here), chose to delay the offering — which is almost always code for pulling it entirely. One possible reason might be that Elixir co-founder Leonard Guarente, a MIT professor sometimes tipped as a future Nobel laureate, decamped from Elixir for Sirtris in November.
