Galectin Therapeutics Inc. (GALT)

[Darwinian]

Any guesses as to what the CTO is about? I'm new to this stuff. Google helps but...
Here's a copy and paste:

Galectin Therapeutics, Inc.
File No. 1-31791 - CF#32232
_____________________
Galectin Therapeutics, Inc. submitted an application under Rule 24b-2 requesting
confidential treatment for information it excluded from the Exhibits to a Form 8-K on
March 12, 2015.
Based on representations by Galectin Therapeutics, Inc. that this information
qualifies as confidential commercial or financial information under the Freedom of
Information Act, 5 U.S.C. 552(b)(4), the Division of Corporation Finance has determined
not to publicly disclose it. Accordingly, excluded information from the following exhibit
will not be released to the public for the time period specified:
Exhibit 10.1 through November 6, 2017
For the Commission, by the Division of Corporation Finance, pursuant to
delegated authority:
Brent J. Fields
Secretary

I guess my question is: what kind of information is likely being described as "confidential commercial or financial information" that shareholders shouldn't know about? I'm not making any judgement on this just trying to learn a bit and maybe assess risk a little bit (if possible).

Thanks.
