However, some of the main elements of the program can be tested. For example, see:

A first experimental test of de Broglie-Bohm theory against standard quantum mechanics (2002)

This excludes many Bohmian type theories. There have been other papers as well. Naturally, the Bohmians reject these experiments. But do far, EVERY proposed theory which gives "almost" identical results to Standard Quantum Mechanics (SQM) has been experimentally rejected. So only Bohmian theories which give 100% identical results to QM - and there may not be any of these possible - can currently claim to be feasible.

The point is: when you look at the details of a full Bohmian theory, it is always different than SQM in some minor respect.
