I'd say it's any drug that can act on the immune system and alter its
function (that's what modulation means, right?). They could be classified
in two groups: immunosupressants (cyclosporine, rapamycine, tacrolimus,
mycofenolate mofetil, glucocorticoids, metothrexate, ciclofosfamide, etc.)
and immunostimulants (levamisol, vaccines?, inactivated BCG, interleukins,
GM-CSF, interferons, maybe some thymic hormones, etc.).
You should go to a pharmacology textbook for a (surely) much better definition
(don't know what's your field, but for medicine, Goodman Gilman's the golden
rule).
Hope it helps,
