You could save it as PDF and place that in Indesign. It won't be editable though.
If you want it editable, then I suggest you use PDF2ID (http://www.recosoft.com/products/pdf2id) to convert the PowerPoint PDF to an editable InDesign file. I represent Recosoft the creators of PDF2ID. You can view how PDF2ID converts a PDF to and InDesign file with below (all elements are live and editable).
