Trial Summary

What is the purpose of this trial?

This research study is studying a research drug called AZD6738 as a possible treatment for Myelodysplastic Syndrome or Chronic Myelomonocytic Leukemia .

Will I have to stop taking my current medications?

The trial requires a washout period (time without taking certain medications) of 5 half-lives for potent inhibitors or inducers of CYP3A4 before starting AZD6738, or three weeks for St. John's Wort. For other medications, the decision will be made on a case-by-case basis with the study doctor.

How is the drug AZD6738 (Ceralasertib) unique for treating myelodysplastic syndrome?

AZD6738 (Ceralasertib) is unique because it targets specific pathways involved in DNA damage response, which is different from other treatments that often focus on inhibiting blood vessel growth or targeting specific mutations. This novel approach may offer a new option for patients with myelodysplastic syndrome who have limited treatment choices.12345

Findings from Research

In a multicenter phase II study involving 39 patients (23 with acute myeloid leukemia and 16 with high-risk myelodysplastic syndrome), the VEGF receptor inhibitor cediranib showed no confirmed responses in treating these conditions, leading to the early closure of the trial.
Despite the lack of efficacy, common adverse events reported included thrombocytopenia, neutropenia, and fatigue, indicating that while the drug was not effective, it did have a safety profile that needs consideration.

Luspatercept has recently been approved as a targeted therapy for treating anemia in myelodysplastic syndromes (MDS) patients who do not respond to erythropoiesis stimulating agents, marking a significant advancement in treatment options.
Ongoing research is focused on developing new targeted therapies that address myeloid lineage signaling pathways and the immune microenvironment, which could enhance treatment strategies for MDS as current options are limited after treatment failures.

The investigational drug enasidenib, which targets IDH2 mutations, has shown a safety profile and potential to improve survival in patients with relapsed or refractory acute myeloid leukemia.
In a clinical trial, enasidenib induced responses in 40.3% of patients, leading to a median overall survival of 9.3 months.
