Ori,

Quoting http://gdal.org/frmt_nitf.html:
"""
 Creation Options:

    * Most file header, imagery header metadata and security fields can be set 
with appropriate creation options (although they are reported as metadata 
item, but must not be set as metadata). For instance setting "FTITLE=Image of 
abandoned missle silo south west of Karsk" in the creation option list would 
result in setting of the FTITLE field in the NITF file header. Use the official 
field names from the NITF specification document; do not put the "NITF_" prefix 
that is reported when asking the metadata list.
"""

The full list of creation options is given by:
gdalinfo --format nitf

In C#, that would be something like

string[] options = new string [] {"FTITLE=mytitle"};

Dataset out_ds = drv.CreateCopy("out.ntf", src_ds, 0, options, null, null);
or
Dataset out_ds = drv.Create("out.ntf", width, height, bands,
                                             DataType.GDT_Byte, options);
