Broncus Tech, medical device maker, files for $86M IPO — Broncus Technologies, a Mountain View, Calif., developer of minimally invasive devices for treating emphysema, filed to raise $86 million in an initial offering. The company’s SEC filing is here.

The Broncus technology is a minimally invasive, catheter-based device that creates new passages to bypass collapsed airways in the lungs caused by chronic smoking and similar issues, enabling trapped air to escape. Broncus is only one of several device companies hoping to treat emphysema; we’ve previously written about Emphasys Medical, which has also filed for an IPO (see the third item here) and Pulmonx (see here).

If at first you don’t succeed: Aegerion Pharma tries again with $86M IPO filing — Aegerion Pharmaceuticals, a Bridgewater, N.J., specialty pharma that withdrew an IPO bid in June, has decided to try again. The company once again aims to raise $86 million in its latest offering, which you can see here.

Our previous coverage of Aegerion, which is working on drugs that lower cholesterol in a new way, is here and here. No word on why the company thinks things are looking better now — of course, it cited the ubiquitous “market conditions” for its earlier withdrawal — but it has definitely returned.

BG Medicine cuts IPO size by 1.5M shares — BG Medicine, a Waltham, Mass., developer of molecular diagnostics that had aimed to go public on Amsterdam’s EuroNext exchange, last week cut its IPO size to 4.5 million shares from six million shares.

The company also appears to have boosted its IPO price, however, and may also have dropped its plan to list in Europe, as it is now pricing its shares in dollars rather than euros and says in its filing that it plans to list on the Nasdaq. In any event, BG Medicine now stands to raise as much as $83 million in the offering.

Reliant Tech formally withdraws IPO — The “skin-rejuvenation” laser maker, which reportedly postponed its IPO a few days ago, has formally withdrawn its filing, noting that terms available in the market are “not sufficiently attractive.” The company had aimed to raise up to $87 million in the offering. Now Reliant Pharmaceuticals, which is also pursuing an IPO, can rest easy.

EXPANDING ITEMS: Stay tuned.

Vaxart 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 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 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.

Featured companies: Allozyne, Arteriocyte Medical Systems, Arthrosurface, Bay City Capital, EnteroMedics, OncoVista, Novotech, Power Medical Interventions, Reliant Technologies

UPDATED: Expanded items on Allozyne, Reliant Tech, Power Medical and Bay City Capital.
UPDATE REDUX: Added item on EnteroMedics IPO.

Seattle’s Allozyne draws $30M for new interferon — Allozyne, a Seattle biotech focused on tweaking existing protein-based drugs to improve their properties, raised $30 million in a second round of financing. Investors included MPM Capital, OVP Venture Partners, Amgen Ventures, ARCH Venture Partners and Alexandria Real Estate Equities.

Allozyne’s twist on improving protein-based drugs — i.e., most biotech drugs — is to substitute “non-natural” amino acids into the proteins themselves. (Recall that a protein is essentially just a long chain of amino acids.) By swapping out natural amino acids with synthetic versions at key points in the protein, Allozyne hopes to improve the effectiveness and safety of protein drugs. The company’s description of it’s approach is here.

The company’s first drug candidate is a modified version of interferon beta, which is currently used to treat multiple sclerosis. The funding will support the first early-stage human trials of the drug, and will also “accelerate” development of a second candidate.

In addition, Allozyne will prepare to exit Accelerator, a Seattle biotech incubator connected with the Institute for Systems Biology. We previously wrote about Accelerator here.

Med-device maker Reliant Tech sets IPO terms, aims for $86M take — Not to be confused with Reliant Pharmaceuticals, which set its IPO terms yesterday, Mountain View, Calif.-based Reliant Technologies set its price range today and now hopes to raise up to $86.5 million in an offering of as many as 5.4 million shares. Reliant hopes to price those shares between $14 and $16 apiece.

Reliant makes medical lasers for “skin rejuvenation” treatments. Our previous coverage of the company is here.

Power Medical IPO falls short, raises up to $49M for robotic-surgery systems — Power Medical Interventions, a Langhorne, Pa., maker of computer- and power-assisted surgery tools, fell short of its IPO hopes and now stands to raise no more than $49 million from its offering. Its latest SEC filing is here.

The company priced its shares at $11 apiece, well under the $12 to $14 range it previously established. (Our coverage is here.) Power Medical could sell as many as 4.4 million shares in the offering.

The result is a sharp disappointment for Power Medical, which had originally hoped to raise as much as $100 million in its offering. The company’s lackluster start contrasts with the soaring welcome spinal-implant maker TranS1 received earlier this month (our coverage here). If it’s any consolation, though, Power Medical shares staged an early recovery, rising 60 cents, or 5.5 percent, to $11.60 in early trading today.

Bay City Capital closes $500M life-science fund — The San Francisco-based VC firm Bay City Capital, which focuses on life-science investments, closed a $500 million fifth fund, VentureWire reports (subscription required). The fund is significantly larger than its predecessor, which closed at $350 million in 2004.

Bay City intends to back 15 to 20 biotech, medical-device and diagnostics companies with the fund, which suggests it will tend to favor later-stage deals — now a long-standing VC trend. The firm told VentureWire that it will invest at all stages, including “seed-stage bets on start-ups launched in-house and structured investments in publicly traded companies.”

EnteroMedics sets IPO terms, looks for $92M to support obesity-control implants — St. Paul, Minn.-based EnteroMedics, a device company developing a neuromodulation implant designed to regulate appetite, set its IPO terms and now aims to offer up to 5.75 million shares at a price of $14 to $16 apiece. The offering could value the company at as much as $261 million while raising up to $92 million.

EnteroMedics is one of several companies angling to introduce new obesity treatments that don’t rely on drugs or invasive surgery. Although its technology is still being tested to assess its effectiveness, EnteroMedics has launched a spiffy new Web site with lots of pictures and animations to illustrate how it believes its implant will work. For our previous coverage of the company, see here and here.

Reliant Tech seeks $95M IPO for dermatology lasers — Mountain View, Calif.-based Reliant Technologies, a developer of medical lasers for “skin rejuvenation” treatment, filed to raise as much as $95 million in an initial offering. The company currently markets two laser systems for skin treatment under the Fraxel brand name, and intends to launch a third one next year.

Oddly enough, Reliant Tech’s IPO filing comes just days after Reliant Pharmaceuticals filed for a $400 million initial offering (see our coverage in this daily briefing). That should certainly keep investors on their toes. Journalists, too — I almost didn’t cover this IPO because I thought I’d already written about it.

Although it has products on the market, Reliant Tech is not only still losing money, its losses are apparently continuing to mount. Total revenues have grown substantially, to $57.4 million in 2006 from $4.5 million in 2004, but its net losses have also kept pace, largely as a result of mounting sales and marketing expenses. Net losses in 2006 were $20.9 million, up from $13.3 million in 2004; for the first half of 2007, the company posted a loss of $10.9 million on $35.3 million in revenue.

Reliant Tech raised $37 million in its two most recent fundings, most recently drawing in $15 million in a fifth round, according to VentureWire (subscription required).

Neuromodulator Leptos raises $20M for obesity implant — Leptos Biomedical, a Brooklyn Center, Minn., developer of obesity-control implants, raised $20 million in a third funding round, VentureWire reports. Investors included Latterell Venture Partners, Spray Venture Partners, Thomas McNerney & Partners and Technology Partners.

Leptos is developing what it calls an “implantable pulse generator” designed to send electric signals into the sympathetic nervous system in order to suppress appetite and induce the burning of fat. The company has apparently already conducted a pilot trial of the device, which it says the new funding will allow it to extend. Leptos hasn’t disclosed additional details about its technology; on its Web site, the page devoted to approach is a two-paragraph stub filled with boilerplate.

I’ve written earlier about EnteroMedics, another company hoping to treat obesity using an implant that interferes with signals transmitted along the vagus nerve — you can read our previous coverage here. In general, the whole field of “neuromodulation” is heating up quite a bit these days, with companies hoping to use timed electrical pulses to the nervous system for treating everything from epilepsy to sleep apnea to hypertension — although it’s worth bearing in mind that almost all of these approaches are so far unproven. See our previous coverage of other companies in this space here, here, here, here, and here.

Founded in 2003, Leptos is the brainchild of serial physician-entrepreneur John Dobak, who previously founded hypothermia-inducer InnerCool Therapies and CryoGen, which developed a cryothermic technique for stanching uterine bleeding. Both companies have since been acquired — InnerCool for $6 million (after raising $49 million) and CryoGen for something between $40 million and $150 million (after raising roughly $60 million).

Skin-clinic chain Calidora raises $4M for SoCal expansion — Calidora Skin Clinic, a chain of four “medical-aesthetic” skin-care clinics in the Seattle area, raised $4 million in a first funding round to expand its operations into southern California. Roughly half the funding was provided by the company’s existing angel investors and insiders, with Fluke Venture Partners providing the rest.

From the release:

Courtion said the funding enables the completion of expansion plans underway in Manhattan Beach, Marina Del Ray, and Glendale, Calif., and other real estate and partnership opportunities on the near horizon. The company is working with Southern California based Caruso Affiliated, a leading retail developer, on two of the three properties, including the Americana at Brand, which is slated to open in downtown Glendale in Spring of 2008.
