Eligibility Criteria

        Inclusion Criteria:

          -  Participants must have advanced, unresectable, and/or metastatic solid tumor
             malignancy that is histologically or cytologically confirmed.

          -  Patients must have received at least 2 lines of therapy in the advanced/metastatic
             setting (if 2 lines exist) and have no other possible therapies or refuse therapies
             that have shown clinical benefit for their condition.

          -  ECOG performance status <1

          -  Ability to understand and the willingness to sign a written informed consent document.

          -  Patients must have measurable disease

          -  Ability to swallow oral medications

        Exclusion Criteria:

          -  Participants who have had chemotherapy or radiotherapy within 3 weeks

          -  Participants may not be receiving any other investigational agents.

          -  Active hepatitis B or hepatitis C infection.

          -  Active or untreated gastric or duodenal ulcer

          -  Symptomatic bowel obstruction within 3 months prior to screening visit.

          -  Symptomatic ascites in the last 4 weeks

        Other protocol defined inclusion/exclusion criteria may apply.
Maximum Eligible Age:100 Years
Minimum Eligible Age:18 Years
Eligible Gender:All
Healthy Volunteers:No

Primary Outcome Measures

Measure:Safety and tolerability of combination cedazuridine with decitabine as assessed by number of participants who experience adverse events
Time Frame:up to 2 years
Safety Issue:
Description:Number of participants who have experienced grade 3 or higher adverse events, as defined by Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0)

Secondary Outcome Measures

Measure:Pharmacokinetics of ASTX727 in solid tumor patients as measured by total exposure
Time Frame:Day 2
Safety Issue:
Description:Total exposure will be calculated as area under the plasma concentration-time curve (AUC) by using non-compartmental methods (Winonlin, version 5.3 or newer) and/or compartmental modeling (Adapt II, release 4.0)
Measure:Pharmacokinetics of ASTX727 in solid tumor patients as measured by maximum concentration (Cmax)
Time Frame:Day 2
Safety Issue:
Description:Cmax (mmol/L) is defined as the maximum concentration of ASTX727 in blood.
Measure:Pharmacokinetics of ASTX727 in solid tumor patients as measured by time to maximum concentration (Tmax)
Time Frame:Day 2
Safety Issue:
Description:Tmax (minutes) is defined as the time to reach maximum concentration of ASTX727 in blood.
Measure:Objective response rate (ORR) in solid tumor patients who are treated with ASTX727
Time Frame:up to 2 years
Safety Issue:
Description:Proportion of participants who had measurable disease at baseline and have been re-evaluated after at least 1 cycle of therapy with observed reduction in tumor burden as defined by RECIST 1.1: Complete response (CR)= disappearance of all target lesions, Partial response (PR)= at least 30% decrease in sum of diameters of target lesions
