Julie Olson has seen the future, and it is in polymers. A former Pfizer executive, Olson is the CEO of Mersana Therapeutics, a 12-person startup in Cambridge, Mass., that is developing a biodegradable, bioļ¾inert polymer called Fleximer, which when linked to certain anticancer agents may make the drugs more soluble, less toxic to the body, and more effective in attacking tumors. In short, Fleximer, if successful, could take a drug that has failed due to high levels of toxicity and help it succeed today.
