stoploss, let me read what the sec doc says.

I am not always the best at understanding them all but will let you know what I believe it is saying if someone does not beat me to it here.

Here is what I walked away in looking at it initially and doing a Google search on what that form is used for. As I take away from it, they are basically consolidating all of the company changes that have been reported from various prior filings recently. I did not notice anything new right off in giving it a skim over.


From AdventRX website. Look for 2/11/10 item on page: http://ir.adventrx.com/phoenix.zhtml?c=75414&p=irol-sec

I looked up to see what the form was meant for when it is filed with the Security Exchange Office. Here is what I found on the web:

What Does SEC Form 424B3 Mean?
The prospectus form that a company is required to file, detailing the information that created a significant change from previously-supplied information provided in the company's prior prospectus filed with the SEC. Companies are required to file prospectus form 424B3 in accordance with Rule 424(b)(3) of the Securities Exchange Act of 1933.

Investopedia explains SEC Form 424B3
The Securities Exchange Act of 1933 was created to help investors make informed decisions by requiring securities issuers to complete and file registration statements (including financial and material information) with the SEC before making an issue available for purchase by the public. Often, registration statements filings required under the Securities Exchange Act of 1933 are also registration statements under the Investment Company Act of 1940.
