Study Of Venetoclax Tablet With Intravenous or Subcutaneous Azacitidine to Assess Change in Disease Activity In Adult Participants With Newly Diagnosed Higher-Risk Myelodysplastic Syndrome

About

Brief Summary

Myelodysplastic Syndrome (MDS) is a group of disorders that gradually affect the ability of a person's bone marrow (semi-liquid tissue present in many bones like backbones) to produce normal blood cells. Some people with MDS have a risk of the disease progressing to acute myeloid leukemia (AML), and a risk of death from the disease itself. Symptoms of MDS include fatigue, shortness of breath, unusual paleness due to anemia (low red blood cell count), easy or unusual bruising, and red spots just beneath the skin caused by bleeding. The purpose of this study is to see how safe and effective venetoclax and azacitidine (AZA) combination are when compared to AZA and a placebo (contains no medicine), in participants with newly diagnosed higher-risk MDS.

Venetoclax is an investigational drug being developed for the treatment of MDS. The study consists of two treatment arms - In one arm, participants will receive venetoclax and AZA. In another arm, participants will receive AZA and placebo. Adult participants with newly diagnosed higher-risk MDS will be enrolled. Around 500 participants will be enrolled in approximately 220 sites worldwide. Participants in one arm will receive oral doses of venetoclax tablet and intravenous (infusion in the vein) or subcutaneous (given under the skin) AZA solution. Participants in another arm will receive oral doses of placebo tablet and intravenous or subcutaneous AZA solution. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood and bone marrow tests, checking for side effects, and completing questionnaires.
