VIDAZA® is the standard of care for higher-risk MDSa patients1
VIDAZA® clinical trials have shown:
- VIDAZA® offers patients
- improved quality of life2
- significantly greater treatment response vs. supportive care3
- significantly delayed time to AML or death vs. supportive care3
- Treatment should be continued as long as the patient continues to benefit or until disease progression.4
- Continued treatment with VIDAZA® can increase response quality in responders4
VIDAZA® has been investigated in two phase III studies, AZA-0015 and CALGB 9221.3
AZA-001 Clinical Study
AZA-001: Efficacy of azacitidine compared with that of conventional care regimens in the treatment of higher-risk myelodysplastic syndromes: a randomised, open-label, phase III study.1
Overall survival. All patients followed until death or study closure
- Time to AML or death, haematological response and improvement
- RBC transfusion independence, infections requiring IV therapy and adverse events
Patients were eligible for enrolment if they were aged ≥ 18 years, with Int-2 or high-risk MDS and RAEB, RAEB-T, or CMML with at least 10% bone marrow blasts with a white blood count below 13 x 109/L1
- Best supportive care was included in each arm
- Treatment continued until unacceptable toxicity, transformation to AML, or disease progression occurred
- No erythropoiesis stimulating agents were allowed1
- 358 patients were randomised at 79 sites
- VIDAZA® (n=179) or CCR (n=179): BSC only (n=105, 59%), LDAC (n=49, 27%), or Intensive CT (n=25, 14%)
- Median age: 69 years (range 38-88 years)
- The VIDAZA® and CCR groups were comparable for baseline (BL) parameters
- at BL, 95% of patients were higher-risk: RAEB (58%), RAEB-T/WHO AML (34%), CMML (3%), and other (5%).
- by IPSS, 89% were higher-risk: Int-2 (43%), High (46%), and 11% indeterminate/other
- VIDAZA® was administered for a median of nine cycles; LDAC for four cycles
- Follow-up period of 21.1 months
- VIDAZA® doubles the 2-year survival rate from 26% to 51% (p<0.0001) compared with conventional care regimens (CCR)
- VIDAZA® treatment was associated with a median overall survival of 24.5 months vs. 15 months for those receiving CCR
- The survival benefits of VIDAZA® were consistent regardless of CCR treatment option used in the control arm
- VIDAZA® led to a significantly reduced need for red blood cell (RBC) transfusions compared to CCR
- VIDAZA® delayed time to AML progression or death in Int-2 and High-risk MDS patients compared to CCR (17.8 months vs. 11.5 months, respectively; p<0.0001)

CALGB 9221 Clinical Study
CALGB 9221: Randomized Controlled Trial of Azacitidine in Patients With the Myelodysplastic Syndrome: A Study of the Cancer and Leukemia Group B1
Overall response (sum of complete response and partial response)
- Overall survival
- Time to AML transformation or death
- Transfusion independence
Patients with refractory anaemia (RA) or RA with ringed sideroblasts (RARS) met additional criteria of significant bone marrow dysfunction.
- Phase III, randomised, controlled trial
- Both arms received transfusions and antibiotics as required
- Patients in supportive care arm (whose disease worsened) were permitted to cross over to VIDAZA® after at least 4 months of supportive care
- Use of all haematopoietic growth factors was prohibited
Adapted from Silverman LR et al. J Clin Oncol 2002; 20:2429-2440.
- Median age: 68 years
- Males (69%)
- The two arms were evenly balanced at entry
- Of the VIDAZA®-treated patients, 7% had a complete response, 16% had a partial response and 37% showed haematological improvement
- Transformation to AML (as a first event) occurred in 15% of patients with VIDAZA® vs. 38% on supportive care (P=0.001)
- Of 65 patients with RBC transfusion dependence at baseline, 45% became transfusion-independent
- The VIDAZA® arm had an increase in the number of RBC transfusions in the first month of treatment, but decreased subsequently
- A landmark analysis conducted to compare survival at six months demonstrated significantly higher survival with VIDAZA® vs. supportive care (18 months vs. 11 months respectively, p=0.03)
- QoL assessments found significant advantages in physical function, symptoms and psychological state for patients who crossed over to VIDAZA® as measured according to the European Organization for Research and Treatment of Cancer (EORTC) and the Mental Health Inventory (MHI)1

a. MDS-specific Indication
VIDAZA® is indicated for the treatment of adult patients who are not eligible for haematopoietic stem cell transplantation with:
- intermediate-2 and high-risk myelodysplastic syndromes (MDS) according to the International Prognostic Scoring System (IPSS),
- chronic myelomonocytic leukaemia (CMML) with 10-29% marrow blasts without myeloproliferative disorder
b. AML-specific Indication:
Treatment of adult AML patients who are not eligible for haematopoietic stem cell transplantation with 20-30% blasts and multi-lineage dysplasia, according to the WHO classification. WHO classifies RAEB-T patients with blasts ≥20% to <30% as AML patients.
