ASTX029 is a synthetic small molecule inhibitor of extracellular signal-regulated kinases (ERKs) 1/2. ASTX029 has not been previously evaluated in human participants. The Phase 1 portion of this study will assess safety and determine the maximum tolerated dose, the recommended Phase 2 dose (RP2D), and the recommended dosing regimen of ASTX029 administered orally. The Phase 2 portion will assess preliminary clinical activity in tumors characterized by gene aberrations in the mitogen-activated protein kinase (MAPK) signal pathway that may confer sensitivity to ASTX029.

Time frame: Cycle 1 (cycle length = 21 days)
DLTs were defined as adverse events (AEs) graded by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v4.03 criteria that occurred during the first cycle of treatment and represented any 1 of the following: grade 4 thrombocytopenia of any duration; ≥grade 3 hematologic toxicity with complications (e.g., grade 3 thrombocytopenia with bleeding or transfusion requirement); febrile neutropenia of any duration or grade 4 neutropenia of 5 days or more duration; liver-associated abnormalities; ≥grade 2 eye disorders; symptomatic grade 2 cutaneous toxicities (including skin rash); any other ≥grade 3 nonhematologic AE except grade 3 nausea, vomiting, or diarrhea; Any event that, in the opinion of the Data and Safety Review Committee (DSRC), would suggest that further dose escalation would put subjects at unacceptable risk.
Time frame: From first dose of study drug up to 30 days after last dose (Up to 74 months)
An AE is defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. TEAEs are defined as events that first occurred or worsened on or after the date of the first dose of study treatment until 30 days after the last dose of study treatment or until the start of a posttreatment alternative anti-cancer treatment, whichever occurs first, with the following exceptions: events that occurred after 30 days beyond the last dose of study treatment or the start of a posttreatment alternative anti-cancer treatment will also be considered treatment-emergent if the events are both serious and related to the study treatment.
Time frame: Every 2 cycles for the first 4 cycles and then every 4 cycles thereafter until disease progression (Up to 74 months)
The ORR was calculated as the number of evaluable participants whose best response was complete response (CR) or partial response (PR), divided by the total number of participants evaluable for ORR analysis. CR was defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or nontarget) must have reduction in short axis to <10 millimeters (mm). PR was defined as at least a 30 percent (%) decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Percentages were rounded off to the nearest single decimal place
Time frame: Pre-dose on Day 1 of Cycles 1 and 2 and at 0.5, 1, 2, 3, 4, 6, and 8 hours post-dose on Day 1 of Cycles 1 and 2 (Cycle length = 21 days)
As per planned analysis, data for participants from Part A (Dose Escalation) and Part B (Expansion) were combined for Cohort 11 (200 mg). 2 participants who received 200 and 280 mg respectively, in Cycle 1 Day1 (C1D1), received 120 mg in Cycle 2 and Day 1 (C2D1) and hence counted in Cohort 10. 1 participant who received 280 mg in C1D1, received 200 mg in C2D1 and hence counted in Cohort 11.

The food effect was to be analyzed only for tablet dosage forms. The participants who were administered 80 mg and 120 mg tablets, under both fed and fasted conditions were reported. As 200 mg dose was administered, as tablets, only under fasted conditions, hence food effect was not assessed for 200 mg dose. The statistical comparison between fed and fasted state treatment arm groups of 80 mg and 120 mg doses is reported in this outcome measure for food effect. The 2 participants who received 200 and 280 mg respectively, in C1D1, received 120 mg in C2D1 and hence counted in Cohort 10.

The protein expression level is quantified through the H-score, calculated from staining intensity within the target cell region. H-Score = (3x % of cells with staining graded 3) + (2x % of cells with staining graded 2) + % of cells with staining graded 1. H-Score ranges between 0 to 300. The H-score is for sum of cytoplasmic H-Score (C pRSK H-Score) and nuclear H-Scores (N pRSK H-Score). C pRSK H-Scores, and nuclear H-Scores were combined to give a single H-score.
Time frame: Every 2 cycles for the first 4 cycles and then every 4 cycles thereafter until disease progression (Up to 82 months)
The PFS was defined as the number of months from the start of the study treatment to disease progression or death, whichever occurs first. The PFS was analyzed using a Kaplan-Meier method, with PFS time being censored on the date of the last disease assessment. The 90% CI for median PFS was provided using the Kaplan-Meier procedure.
Time frame: Up to 82 months
The OS was defined as the number of months from the day the participant was randomized to the date of death (regardless of cause). Participants without a documented death date were censored on the last date they were known to be alive. The OS was presented using a Kaplan-Meier estimate.
The 90% CI for median OS was provided using the Kaplan-Meier procedure.
Time frame: Every 2 cycles for the first 4 cycles and then every 4 cycles thereafter until disease progression (Up to 82 months)
DCR was calculated as the number of participants whose best response was CR, PR, or stable disease (SD), divided by the total number of participants evaluable for DCR analysis. CR was defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or nontarget) must have reduction in short axis to <10 mm. PR was defined as at least a 30 % decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Stable disease was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD), taking as reference the smallest sum diameters while on study. Percentages were rounded off to the nearest single decimal place.
Time frame: Every 2 cycles for the first 4 cycles and then every 4 cycles thereafter until disease progression (Up to 82 months)
Duration of response was calculated for all responders from the date of the earliest assessment of CR or PR to the date of relapse or death, whichever occurred earlier, or the last disease assessment date for participants without a relapse or death. Duration of SD was calculated for participants whose best response is CR, PR, or SD from the day study drug was first taken to the date of disease progression or death, whichever occurred earlier, or the last disease assessment for participants without disease progression or death.
