Study Summary

This trial is testing the combination of seclidemstat and azacitidine to treat patients with myelodysplastic syndrome or chronic myelomonocytic leukemia.

Who is the study for?
Adults diagnosed with myelodysplastic syndrome or chronic myelomonocytic leukemia, who haven't responded to certain treatments like azacitidine, can join this trial. They must understand the study and agree to participate, have proper kidney and liver function, an ECOG performance status of 0-2, and not be pregnant or breastfeeding. Those with uncontrolled infections, heart issues, or taking specific drugs that affect the trial medications are excluded.Check my eligibility
What is being tested?
The trial is testing the combination of seclidemstat and azacitidine to determine the best dose for treating certain blood cancers. Seclidemstat blocks enzymes needed for cancer cell growth while azacitidine may prevent cancerous growths from forming. The goal is to see if this combo kills more cancer cells.See study design
What are the potential side effects?
Potential side effects include reactions related to enzyme inhibition which could affect cell growth in general leading to fatigue, digestive issues or blood disorders. Azacitidine might cause nausea, vomiting or injection site reactions. Organ inflammation and increased risk of infection are also possible.

Experimental Treatment
Group I: Treatment (azacitidine, seclidemstat)Experimental Treatment2 Interventions
Patients receive azacitidine IV over 10-40 minutes or SC on days 1-7. Patients also receive seclidemstat PO QD on day 1 of cycle 1 and PO BID on days 2-28 of cycle 1 and on days 1-28 of all subsequent cycles. There are 6 planned dose levels for seclidemstat: 300 mg, 450 mg, 600 mg, 900 mg, 1200 mg and 1500 mg. Successive cohorts of eligible patients will be treated with azacitidine. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
