Like the Cathars.
No, tragically the Catholic Church did repress the Cathars into obscurity. (This is a tragedy because of the means of the repression; the Cathars were amazing sick, vile perverts, not the proto-Protestants of restorationist fantasies.) Contrarily, the Hussites went extinct largely because they killed themselves off by warring amongst themselves... and the survivors eagerly chose one of two non-Hussite camps, reformed Christians or Catholic Christians, rather than face such horrific intramural violence.
