What is AZACITIDINE?
AZACITIDINE (marketed as Vidaza) is an approved hypomethylating agent used primarily in treating myelodysplastic syndromes (MDS), acute myeloid leukemia (AML), and other hematologic malignancies. It functions by inhibiting DNA methyltransferase, leading to DNA demethylation and reactivation of tumor suppressor genes.
Market Overview
Therapeutic Indications
- Myelodysplastic syndromes (MDS)
- Acute myeloid leukemia (AML)
- Chronic myelomonocytic leukemia (CMML)
Size and Growth
- The global MDS treatment market was valued at approximately $1.2 billion in 2022.
- The AML drug market exceeds $4.4 billion annually.
- CAGR projections for hematologic malignancies treatments: 8% over the next five years (Research and Markets, 2021).
