BOSTON ( TheStreet) -- Back by popular demand, TheStreet's FDA Drug Approval Contest for 2013 -- with a few twists.

Your challenge: Correctly guess the outcome of the 12 regulatory events listed below. As a kicker to the contest, you're required to predict the outcome of a closely followed European drug approval decision, three FDA advisory panels and an accelerated approval meeting between a certain drug company and FDA officials.

Don't forget to answer the bonus question, as well.

To participate in the drug approval contest, please post your predictions to each of the 13 questions in the comments section under this story. Post your picks by Friday, March 8 at 4 pm ET. Entries posted after the deadline will not count, so don't be tardy with your picks. Enter now!

As with my previous drug-approval contests, winners will be lauded for their intelligence on Twitter and in future columns. Losers will be mocked gently.

Good luck!
