ClinConnect Summary

This clinical trial is looking at a new treatment approach for patients with advanced blood disorders, specifically myelodysplastic syndromes (MDS), chronic myelomonocytic leukemia (CMML-2), and secondary acute myeloid leukemia (sAML). The treatment combines umbilical cord blood stem cells from healthy donors with an existing medication called azacitidine. The goal is to see if this combination is effective and safe for patients who cannot undergo standard stem cell transplants.

To participate in this study, individuals must be between 18 and 80 years old and have specific types of blood disorders that fit certain medical criteria. They should not have other serious health issues that could complicate their treatment. Participants can expect to receive close medical supervision throughout the trial, and they will need to sign a consent form to show they understand the study's purpose and procedures. This trial is currently recruiting participants, and it aims to better understand how this combined treatment might help those with advanced blood cancers.
