create controllers/admin/AdminPageController.php with the follwing content:

    class AdminPageController extends AdminController
    {
        public function initContent()
        {
            parent::initContent();
            $smarty = $this->context->smarty;

            $smarty->assign('test', 'test1');

        }
    }

Delete: /cache/class_index.php

Create: admin\themes\default\template\controllers\page\content.tpl

At BackOffice -> Administration -> Menus -> [Add New]:

Name: Page
Class: AdminPage
Parent: Catalog

Click the [Save] button and the menu item should appear at the "Catalog" menu.
