Study Details

Study Description

Brief Summary

Treatment of patients with WHO defined IPSS int 2 and high risk MDS , AML with 20-30% marrow blasts and CMML type 2, after failure of azacitidine or decitabine exposure for at least 6 courses, or relapse after initial response.

Condition or Disease	Intervention/Treatment	Phase
MDS	Drug: SGI-110 administration	Phase 2

Detailed Description

All eligible patients will be treated with SGI-110 for 9 cycles of 28 days.

Patients who meet eligibility criteria will be administered subcutaneous SGI-110 at 60mg/m²/d one time daily for 5 days. Each cycle will last 28 days with SGI-110 starting on day 1 of each cycle. Patients will receive at least 9 cycles unless overt progression is documented. (Overt progression will be defined by the presence of more than 30% marrow blasts and doubling of marrow blast percentage from onset of SGI-110). Dose reduction to 45 and even 30 mg/m²/d will be made in case of toxicity.

Patients with Complete Remission (CR), Partial Remission (PR), marrow CR, Hematological Improvement (HI) or stable disease (SD) after 6 Cycles of therapy (IWG 2006 criteria) may receive 3 additional cycles. Response will be re-evaluated after 9 cycles. Patients with no response (NR) to treatment after 9 cycles will be withdrawn from the protocol. Patients with progression at any time will be withdrawn from the protocol after the last treatment Cycle.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: SGI-110	Drug: SGI-110 administration SGI-110 will be administered SC at 60 mg/m²/day x5 consecutive days for each cycle. Cycle duration is 28 days. Patients with Complete Remission (CR), Partial Remission (PR), marrow CR or Hematological Improvement (HI) after 6 Cycles of therapy (IWG 2006 criteria) may continue treatment until progression. A dose reduction to 45 and even 30 mg/m²/day will be made in case of haematological toxicity. Patients with no response (NR) to treatment will be withdrawn from the protocol after the last treatment Cycle.

Outcome Measures

Primary Outcome Measures

Response rate [6 month]
Number of complete Remission (CR), CR with incomplete hematological recovery (CRi), Partial Remission (PR), Marrow CR and Hematological Improvement (HI) according to IWG 2006 criteria after 6 treatment cycles

Secondary Outcome Measures

Duration of response [4 years]
Measured from the date an objective response was achieved to the date of relapse or progression (cf. definition in appendix 5) or the date of last contact if no event occurred.
Adverse event [After 1 month]
Patients must have received at least one dose of treatment in order to be considered evaluable for toxicity.

Eligibility Criteria

Criteria
