Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Given the toxic effects of disulfiram when administered within 14 days of ingesting ethanol, participants were required to agree not to drink alcohol during the study and for 14 days after its completion.

Reporting Groups
Disulfiram Low Dose 250mg Dose First 9 subjects were assigned to the low dose (250mg) arm. These subjects took 250mg daily for 28 days per cycle.
Disulfiram High Dose 500mg Dose After accrual to the low dose was complete,ten subjects were assigned to the high dose (500mg) arm. These subjects took 500mg daily for 28 days per cycle.
