vaxart-logo.jpgVaxart receives $3.3M for oral vaccines — San Francisco’s Vaxart, a biotech developing novel adenovirus-based vaccines, raised $2.7 million in a first funding round. Vaxart also received a $600,000 small-business innovation grant from the NIH to assist in developing the company’s vaccine platform.

Vaxart’s vaccine technology involves a non-replicating adenovirus engineered to produce a particular bacterial or viral protein, or antigen, which stimulates an immune response. The vaccine, which consists of the adenovirus and an “adjuvant” designed to enhance the immune response, is packaged in a capsule that can be taken by mouth.

Vaccines that depend on viral “vectors” like adenovirus are promising because they can produce immunity without the need to rely on attenuated or killed disease virus. When injected, however, such vaccines frequently stimulate an immune reaction to the adenovirus itself, which can negate the effect of the vaccine or subsequent booster shots. Vaxart believes that oral delivery can sidestep that problem.

The company’s early candidates include vaccines against avian flu, seasonal flu, and biowarfare agents. Investors in the round included Quantum Technology Partners, Life Science Angels, Bay Partners and Sand Hill Angels.

reliant-tech-logo.jpgReliant Tech postpones IPO — Reliant Technologies, the Mountain View, Calif., maker of laser skin treatments, postponed its IPO indefinitely, PE Hub reports. The medical-device maker had previously filed to raise up to $86.5 million in an offer of 5.4 million shares.

Reliant Tech’s postponement comes just a day after EnteroMedics, a maker of obesity-control devices, almost halved its IPO pricing. Until recently, device makers had lived a charmed life where IPOs were concerned, but it’s beginning to look as though market turmoil may be taking its toll on this sector as well. Our previous coverage of the company is here and here.

On the other hand, at least IPO investors won’t get the company confused with Reliant Pharmaceuticals anymore.

n-spine-logo.jpgN Spine acquired by Synthes for $30M — N Spine, a San Diego maker of spinal devices, was acquired by Switzerland’s Synthes for $30 million. The release is here. N Spine shareholders also stand to receive an additional $45 million in milestone payments if development of the company’s products proceeds as planned. Our previous coverage of N Spine’s fundraising is here.

Zosano Pharma raises $45M for needle-free drugs — Fremont, Calif.-based Zosano Pharma, a specialty pharma working on needle-free drug delivery, raised $45 million in the second half of its initial venture funding. The company said it has now raised a total of $90 million. Our previous coverage of the company, which used to be called Macroflux, is here (last item).

Investors included New Enterprise Associates, Nomura Phase4 Ventures, HBM BioVentures and ProQuest Investments. Zosano’s lead candidate is a patch for delivering the drug PTH through the skin to treat osteoporosis.
