Study of Vidaza (Azacitidine) Versus Support Treatment in Patients With Low Risk Myelodysplastic Syndrome (Low and Intermediate-1 IPSS) Without the 5q Deletion and Transfusion Dependent Anaemia

• Status: Completed
• Trial end date: 2015-12-01
• Target enrollment: 0
• Participant gender: All

Summary

Primary Outcome Measures:

• To evaluate the efficacy of treatment with Azacitidine in patients with transfusion-dependent, low risk International Prognostic Scoring System (IPSS) 0 int-1, Myelodysplastic Syndrome (MDS) without chromosome 5 (5q) deletion. The main objective will be based on the erythroid haematologic response according to International Working Group (IWG) 2006 criteria.

Secondary Outcome Measures:

• Haematologic response, bases on the following parameters: platelets, and neutrophils according to International Working Group (IWG) Criteria.

• Medullary and cytogenetic response according to International Working Group (IWG) 2006 criteria.

• The effect of treatment response on quality of life, through the Functional Assessment of Cancer Therapy-Anemia (FACT-an) questionnaire.

• Overall survival, Event-Free Survival and the Acute Leukaemia Transformation Rate.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

6. Patients who are not candidates for intensive chemotherapy and transplant modalities.

7. Patients with an Eastern Cooperative Oncology Group (ECOG) score ≤ 3

8. Women of child-bearing age and heterosexual men whose partner is of child-bearing age, must undertake to use an effective contraceptive method for the duration of the treatment and for at least 3 months alter is has finalised.

Exclusion Criteria:

1. The presence of a psychiatric or medical disease which prevents the patient from signing of the informed consent.
