Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Phase 1: Number of Participants with Adverse Events (AE)	An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational or non investigational) product, whether or not related to that medicinal (investigational or non investigational) product.	Up to 1 year and 5 months
Primary	Phase 1: Number of Participants with Serious Adverse Events (SAE)	A SAE is any untoward medical occurrence that at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; is a suspected transmission of any infectious agent via a medicinal product; is medically important.	Up to 1 year and 5 months
Primary	Phase 1: Number of Participants with Dose Limiting Toxicity (DLT)	Number of participants with DLT will be assessed. The DLTs are specific adverse events and are defined as any of the following: high grade non-hematologic toxicity, or hematologic toxicity.	Up to 28 days

Secondary	Phase 1 and Phase 2: Time to Response (TTR)	TTR is defined as the time between date of first dose of study treatment and the first efficacy evaluation that the participant has met all criteria for PR or better.	Up to 1 year and 5 months
Secondary	Phase 2: Very Good Partial Response (VGPR) or Better Response Rate (Stringent Complete Response [sCR]+ Complete Response [CR]+VGPR)	VGPR or better response rate (sCR+CR+VGPR) is defined as the percentage of participants who achieve a VGPR or better response according to the 2016 IMWG response criteria.	Up to 1 year and 5 months
Secondary	Phase 2: Complete Response (CR) or Better Response Rate	CR or better response rate is defined as the percentage of participants who achieve a CR or better response (sCR+CR) according to the IMWG 2016 criteria.	Up to 1 year and 5 months
