What's left to value Medivation on? The company has just one other drug in the clinic: prostate cancer treatment MDV3100. The drug is in a pair of phase 3 trials, one of which is fully enrolled with potential for interim results this year.
If you assume dimebon has no value, Medivation's entire $500 million enterprise value is tied up in MDV3100, which seems about right. With no other drugs to fall back on, Medivation is about as high-risk, high-reward as they get.
