First- New Drug Application. It is what you file to request FDA approval to sell a drug. Most are 100's of thousands of pages long. At least now they have electronic filing.
Second, I don't like giving direct investment advice. However, if I had any of this stock above the current price, I'd sell it, put the money away, and buy back when all the overhead is gone in a few years.
You can still trade it. But what are you going to make and at what risk? The stock is in a range now, from about 0.0145 to about 0.019. So if you bought at the low and sold at the high you can make half a cent on each trip. So for 100,000 you make $500 a trade, if you are lucky. Not worth the risk in my book.
