December 25, 2014

We analyzed data from whole-exome sequencing of DNA in peripheral-blood cells from 12,380 persons, unselected for cancer or hematologic phenotypes.

Study Overview

• Clonal hematopoiesis with somatic mutations was observed in 10% of otherwise healthy people > 65 years of age but in only 1% of those < 50 years of age.

• Detectable clonal expansions most frequently involved somatic mutations in three genes (DNMT3A , ASXL1 , and TET2 ) that have previously been implicated in hematologic cancers.

• The risk of hematologic cancer was substantially increased among these persons:

- Clonal hematopoiesis was a strong risk factor for subsequent hematologic cancer (HR, 12.9; 95% CI, 5.8 to 28.7).

- 42% of hematologic cancers in persons with previous detectable clonality.

Clonal Expansion of Pre-leukemic Mutations

Model for the expansion of a single hematopoietic stem cell into a clonal population, under the influence of a somatic mutation (yellow circle), and the potential conversion of the clone into a hematologic cancer through subsequent mutation (black circle with red rim).

DNMT3A in NPM1mut AMLHigh stability & persistence in remission

Schnittger S, et al.-MLL lab (abst. 122, session 617)

• DNMT3A is a stable mutation in NPM1 AML cases

- DNMT3A is retained at relapse in 57/61 (93%) cases with paired

diagnosis – relapse samples.

• DNMT3A as a potential pre-leukemic mutation

- DNMT3A persisted in remission samples in 32/54 (59%)

patients with NPM1 clearance.

• Persistence of DNMT3A at remission is associated to

worse prognosis:

- EFS: 38 vs 96 mos (p=0.03)

- OS: 69 vs. 96 mos (p=0.053)

Study design of the phase III randomised AZA-AML-001 trial

AZA = azacitidine; CCR = conventional care regimens; allo-HSCT = allogeneic haematopoietic stem cell transplantation; BM = bone marrow; ECOG PS = Eastern Cooperative Oncology Group Performance Status; IC = intensive chemotherapy; LDAC = low-dose cytarabine; BSC = best supportive care; SC = subcutaneous; BID = twice daily; OS = overall survival

and Gimema Leukemia Groups

Conclusions:

• Compared with BSC including hydroxyurea as necessary, GO 6 mg/m2 day 1 and 3 mg/m2 day 8 significantly improved OS in elderly AML pts not considered fit for intensive chemotherapy, with an acceptable safety profile.

• The benefit of GO were greater in pts presenting with better-risk cytogenetics, high CD33 expression on blast cells, or secondary disease.
