Study Details
Timeline
Interventions
The participants will take study drug digoxin, which is approved by FDA for the treatment of CHF, 125 or 250 mcg orally daily, titrated to the level of 0.8 - 2 ng/ml for total of 6 cycles (4 weeks/cycle). The lower dose of digoxin (such as 125 mcg/day) will be chosen if serum level reaches 0.8 ng/ml already. Patients may continue another 6 cycles if evident of clinical benefit. It is possible that some patients may need to receive 500 mcg per day to reach this targeted drug level. No further titration will be allowed beyond this FDA approved digoxin dose.
