A Diagnostics & Imaging Week

Genomic Health (Redwood City, California) raised $46.5 million in a public offering to fund development and expansion of its genomics-based clinical diagnostic tests in cancer applications.

The company, which disclosed the offering earlier this month sold 3 million shares at $15.50 a share. Underwriters have an option to purchase up to another 450,000 shares to cover any over-allotments.

Genomic Health in 2004 launched its first test, Oncotype DX, which is used to predict the likelihood of cancer recurrence, the likelihood of patient survival within 10 years of diagnosis and the likelihood of chemotherapy benefit in early stage breast cancer patients. The company, founded in 2000, went public in September 2005, raising about $60.2 million in an IPO at $12 per share.

The Oncotype DX test uses quantitative genomic analysis in standard tumor pathology specimens to provide tumor-specific information, or the oncotype, of a tumor, to improve cancer treatment decisions. The clinical laboratory service entails analyzing the expression levels of 21 genes in tumor tissue samples, which generates a recurrence score based on tumor’s aggressiveness, a score believed to be correlated with the likelihood of chemotherapy benefit. The test costs $3,460.

Genomic Health is conducting clinical studies in an attempt to expand the clinical utility of Oncotype DX in breast cancer, and is developing the product for similar diagnoses in patients with early stages of colon, prostate, renal cell and lung cancers and melanoma.

One study, to be reported at the upcoming American Society of Clinical Oncology meeting, was completed in node-positive breast cancer. Data support further investigation for prediction of recurrence, Genomic Health said. It also plans a second study focused on identifying patients more likely to benefit from anthracycline-based chemotherapy regimens. If successful, the company said, the studies could support launch for the expanded use in those patients in 2008.

Other studies are testing the utility of gene scores, the use of the product in other patient populations, and use with different chemotherapy classes.

The company said its strategy is to identify treatment decisions that can benefit from, and be guided by, the patient’s individual genomic information. A goal is to make its genomic-based tests a standard of care, delivering information after diagnosis but prior to the decision to undergo a specific cancer treatment. It said treatment decisions now are being made with little understanding of the molecular profile of each tumor, resulting in economic inefficiencies.

Genomic Health on March 31 reported cash and equivalents of $35.1 million. Following the offering, it had about 27.6 million shares outstanding, as well as options outstanding on another 3 million shares at an average exercise price of $9.94.

J.P. Morgan Securities is sole book-running manager for the offering, with Lehman Brothers. the co-lead manager. Piper Jaffray & Co. and JMP Securities are co-managers.

The company said the net offering proceeds will be used to fund R&D work, sales and marketing expenses and recent acquisitions, including the exclusive distribution rights to PLC Medical System’s (Franklin, Massachusetts) Heart Laser System for transmyocardial revascularization in the U.S.; the acquisition of certain business assets of Xillix Technologies (Richmond, British Columbia); and for general corporate purposes.

Novadaq first disclosed the offering earlier this month and increased the number of shares in the offering from 2 million to 4 million last week.

• Helicos BioSciences (Cambridge, Massachusetts), the developer of a system for genetic analysis, has lowered the expected price of its initial public offering for a second time to $9 a share, according to a regulatory filing Thursday with the Securities and Exchange Commission.

Last week, Helicos reduced the expected price range of its offering of 5.4 million shares to $10 to $11 per share, from its previous anticipated range of $13 to $15 per share.

The company’s IPO is set to price this week.

Helicos now expects to raise about $43.2 million from the offering, or about $50 million if the underwriters fully exercise their option to buy an additional 810,000 shares to cover over-allotments.

According to Helicos, some existing shareholders may purchase up to $12 million of common stock at the public offering price, or up to 1.3 million shares. Previously, the company said the shareholders may purchase at least $5 million of the stock at the offering price.

The company said it plans to use the proceeds for working capital and other general corporate purposes, including R&D, recruitment of sales, marketing and service personnel, marketing initiatives and startup manufacturing expenses.

Helicos said it plans to launch its first commercial product for the analysis of genetic material, the HeliScope system, in 4Q07.

The company will have 20.5 million shares outstanding following the offering.

UBS Securities is serving as the lead underwriter for the offering. JP Morgan Securities, Leerink Swann and Pacific Growth Equities are also helping to sell shares to investors.

The company plans to list its shares on the NASDAQ Global Market under the symbol HLCS.

Helicos serves the research, clinical diagnostic, and drug discovery markets, providing customers with the ability to compare thousands of samples. The HeliScope system, which can be integrated into existing laboratories, consists of a computer-controlled instrument and related supplies and reagents.
