The price of shares at San Diego’s Gen-Probe, Amylin Pharmaceuticals, and Optimer were clipped for various reasons over the past week, but several local startups successfully raised capital. Our good news, bad news briefing begins here.

Rempex Pharmaceuticals, a San Diego biopharmaceutical startup developing a new approach to antibiotics resistance, said it raised $67.5 million in Series B venture funding—bringing total funding for the company to $76 million since its founding less than five months ago. The startup is on a fast track, and plans to use the capital to accelerate the commercialization of its therapies for treating gram-negative bacterial infections. Rempex said it plans to file a new drug application for its first drug candidate in the second half of 2012. New investors Frazier Healthcare Ventures and Vivo Ventures joined existing investors SV Life Sciences, OrbiMed Advisors, and Adams Street Partners in the latest round.

—Cambridge, MA-based Vertex (NASDAQ: VRTX) has held the high ground in hepatitis C therapies since the FDA approved its protease inhibitor drug telaprevir (Incivek) last year. But two rivals are gaining ground. The price of Vertex shares have fallen with the rise of Alpharetta, GA-based Inhibitex (NASDAQ: INHX) and Princeton, NJ-based Pharmasset (NASDAQ: VRUS). Vertex, which has operations in San Diego, hit a 52-week high of $58.87 on May 12, but it has been trading around $31 in recent days.

The company raised $2.8M in 2010.

—San Diego-based Amylin Pharmaceuticals (NASDAQ: AMLN) agreed to pay Eli Lilly more than $1.5 billion as it gradually reassumes responsibility for global commercialization of its best-selling diabetes drug in a deal that ends its 10-year partnership with Lilly. Under their agreement, which also ends litigation with Lilly, Amylin will take over sales of exenatide (Byetta) in the U.S. by the end of this month—and global sales of both Byetta and an experimental, extended release version (Bydureon) over the next two years. Amylin shares, which hit a 52-week high of $16.65 on Jan. 27, have been trading around $10 a share over the past few weeks.
