UIApplication uiap = commandData.Application;
UIDocument uidoc = uiap.ActiveUIDocument;
Document doc = uidoc.Document;
string ListSchedule = "";
FilteredElementCollector fi = new FilteredElementCollector(doc);
fi.OfCategory(BuiltInCategory.OST_Schedules);
fi.OfClass(typeof(ViewSchedule));

The "Drawn By" parameter is stored in the sheet view object. Here is a quick bit of code to change the parameter value on all sheets...

public void ReplaceDrawnBy()
{
    Document doc = this.ActiveUIDocument.Document;
    
    string newValue = "Joe Drafter";
    
    using (Transaction t = new Transaction(doc, "Replace Drawn By Parameter"))
    {
        t.Start();
        
        foreach (ViewSheet vs in new FilteredElementCollector(doc).OfClass(typeof(ViewSheet)))
        {
            vs.get_Parameter(BuiltInParameter.SHEET_DRAWN_BY).Set(newValue);
        }
        
        t.Commit();
    }
}
