Another San Diego life sciences company is in line for an IPO, and the untimely death of Connect CEO Duane Roth has left a void in the leadership of San Diego’s innovation community. Here’s our review of developments over the past week.

—San Diego’s Sophiris Bio is nearing its debut as a U.S. public company, after setting its terms last week at about $13 per share in an initial public offering of 5 million shares. Sophiris said it plans to use net proceeds of $66 million to initiate two late-stage clinical trials of its drug PRX302 (Topsalysin) to treat non-cancerous prostate enlargement.

Tavistock, which also has invested in San Diego’s Ambryx and Kalypsys, will hold an 11.5 percent stake post-IPO.
