Preemptive drug DEC-C after transplant to reduce hidden cancer
This trial tests whether giving DEC-C (a decitabine-based treatment) soon after an allogeneic transplant can improve outcomes for MDS patients who still have “measurable residual disease” (hidden leftover disease) detectable by a genetic test. It also compares this approach to standard observation if the hidden disease is not detected or if the higher-risk safety checks are not met.
