The currently most promising of these mutant proteins appears to be the double-mutated LT with modifications in both residues 192 and 211 of the LTA subunit to inhibit toxin "nicking" and thus the enterotoxicity of the molecule; this molecule is currently scheduled for phase I clinical trials of its safety in humans when administrated in different dosages.
