- Overall Hematological Response Rate of Participants after Treatment with Imetelstat [ Time Frame: After 4 Months of Treatment ]
The combined response assessment criteria for MDS and AML based on IWG 2018 criteria (MDS) and the criteria of the European LeukemiaNet (AML) will be used to define responders.
The response rate is calculated as number of responders divided by the number of all participants of the analysis set.

- A woman of childbearing potential must have a negative serum or urine pregnancy test at screening and agree to be tested on day 1 of every cycle and at End of Treatment (EOT)
- A man who is sexually active with a woman of childbearing potential and has not had a vasectomy must agree to use a barrier method of birth control. For males, these restrictions apply for 3 months after the end of dosing
Exclusion Criteria:

- Prior history of intensive chemotherapy or hematopoietic stem cell transplant
- Major surgery within 4 weeks prior to day 1 of Cycle 1 (excluding the placement of vascular access and other minor surgical procedures)
- Diagnosed or treated for malignancy other than MDS or AML, except:
Malignancy treated with curative intent and with no known active disease present for 3 years before day 1 of Cycle 1 Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease Adequately treated cervical carcinoma in situ without evidence of disease
- Clinically significant cardiovascular disease such as uncontrolled or symptomatic arrhythmias, congestive heart failure, or myocardial infarction within 6 months of day 1 of Cycle 1, or any Class 3 (moderate) or Class 4 (severe) cardiac disease as defined by the New York Heart Association Functional Classification
