September 2, 2005 Public biotech companies did not generate much news today, the last trading session before a long holiday weekend, but a number of biotech companies provided details about their upcoming IPOs. SGX Pharma, a cancer company known until recently as Structural GenomiX, made its initial filing, saying it hopes to raise $80 million, Intarcia, focused on cancer and infectious diseases, will offer 5 million shares between $12 and $14, Sunesis, touting its cancer drugs and high-powered partnerships, made known its plans to sell 6 million shares between $9 and $11, and SkinMedica, a dermatology company, will offer 5.25 million shares between $11 and $13. IPOs need the support of an uptrending market, and biotech closed out a good week (up 2.8%) with a small loss as the Centient Biotech 200 slipped 15 points to end at 3854.82, a drop of .39%.
