FT-2102

DLTs are AEs unrelated to the underlying disease and considered related to FT-2102. For non-hematologic AEs: Grade 3 or higher per CTCAE v 4.03 criteria except Grade 3 nausea, vomiting, diarrhea, or rash: lasting \<72 hours (with optimal medical management) or clinically relevant Grade 3 or higher non-hematologic laboratory finding. For hematologic AEs: Grade 3 or higher thrombocytopenia or febrile neutropenia or Grade 4 or higher neutropenia lasting for \>7 days.

ORR is defined as the proportion of patients who achieved a complete response (CR) or partial response (PR) as per RANO (2010) criteria for patients with high grade glioma (Cohorts 1a and 1b). For patients with low grade glioma, ORR is defined as CR+PR+minor response (MR) as per LGG RANO criteria (2011). For Cohorts 2-5, ORR is defined as CR+PR as per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria.

A TEAE was defined as an adverse event (AE) that emerges during treatment, having been absent pre-treatment, or worsens relative to the pre-treatment state. An AE was defined as any unfavourable and unintended sign (including an abnormal laboratory finding), symptom or disease temporally associated with the use of a product, whether or not considered related to the product. A serious adverse event (SAE) is defined as any untoward medical occurrence that at any dose results in death, or is life-threatening, or requires inpatient hospitalization or causes prolongation of existing hospitalization results in persistent or significant disability/incapacity, or may have caused a congenital anomaly/birth defect, or requires intervention to prevent permanent impairment or damage. Number of participants with TEAEs and SAEs is reported. Safety analysis set (SAS) included all the participants who have received at least one dose of study drug (FT-2102, azacitidine, or cytarabine).

Number of participants with change from baseline in clinically significant abnormal laboratory values for hematology, chemistry and coagulation with Grade \<1 to 4 is reported. National Cancer Institute - Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 4.03 toxicity grade used to determine severity of AE. Grade 1: mild;asymptomatic/mild symptoms; Grade 2: moderate; minimal; Grade 3: severe/medically significant; Grade 4: life-threatening consequences, Grade 5: death.

Number of participants with change from baseline in clinically significant abnormal ECG parameter (QTcF) is reported. QT interval was the time between the start of the Q wave and the end of the T wave in the cardiac electrical cycle. QTcF was the QT interval corrected for heart rate using Fridericia's formula: QTcF = QT divided by cube root of 60/heart rate.

Percentage of participants with CR plus CRh (CR, Molecular CR \[CRm\], Cytogenetic CR \[CRc\], CRh) is re-ported. CR is defined as bone marrow blasts less than (\<) 5 percent (%) (in aspirate with spicules and 200 nucleated cells), no blasts with auer rods, no extramedullary disease, absolute neutrophil count (ANC) greater than or equal to (\>=) 1000/μL, platelet count \>=100,000/μL and transfusion independ-ence. CRc is defined as CR with no residual cytogenetic abnormalities. CRm is defined as CR with unde-tectable IDH1m minimal residual disease (MRD) and CRh is defined as bone marrow blasts and partial recovery of peripheral blood counts (platelet count \>50 × 10\^9/L and ANC \> 0.5 × 10\^9/L).

Percentage of participants with CR plus CRh (CR, Molecular CR \[CRm\]), Cytogenetic CR \[CRc\], CRh) is re-ported. CR is defined as bone marrow blasts \<5 % (in aspirate with spicules and 200 nucleated cells), no blasts with auer rods, no extramedullary disease, ANC \>=1000/μL, platelet count \>=100,000/μL and transfusion independ-ence. CRc is defined as CR with no residual cytogenetic abnormalities. CRm is de-fined as CR with undetectable IDH1m MRD and CRh is defined as bone marrow blasts and partial recovery of peripheral blood counts (platelet count \>50 × 10\^9/L and ANC \> 0.5 × 10\^9/L).

Percentage of participants with complete remission (CR) is reported. CR is defined as bone marrow blast ≤ 5% myeloblasts with normal maturation of all cell lines, peripheral blood: Hgb ≥11 grams per deciliter (g/dL), platelets ≥ 100 × 10\^9/L, neutrophils ≥ 1.0 × 10\^9/L and blasts 0%.

RFS is defined as the time between the date of first dose until relapse or death from any cause, whichever occurs first. RFS is calculated for all participants in Phase 2 Cohort 2. 4-Month RFS rate is defined as the percentage of participants in Phase 2 Cohort 2 who have not relapsed or died on or before their 4-month response evaluation.
