Angularjs called from an extension?
Ok, sorted it out with some suggestions and examples.

$loader = new \Civi\Angular\AngularLoader();
$loader-&gt;setModules(array('trialadmin'));
$loader-&gt;setPageName('Administration');
$loader-&gt;useApp(['activeRoute' =&gt; '/trialadmin/trialdetails']);
$loader-&gt;load();

Worked with this, but I also used the trace and debug in the browser to determine there likely was another issue with the form actually loading.  Regardless, I've been able to sort it out.
