Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 100 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • ECOG performance status <1
  • Ability to understand and the willingness to sign a written informed consent document.
  • Patients must have measurable disease

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Safety and tolerability of combination cedazuridine with decitabine as assessed by number of participants who experience adverse events
Time Frame: up to 2 years
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)
up to 2 years
Maximum Tolerated Dose (MTD) as determined by number of participants with of dose limiting toxicities (DLT)
Time Frame: up to 2 years
Maximum tolerated dose will be determined by the maximum dose at which the least number of participants experience dose-limiting toxicity. The dose limiting toxicity is defined using the Common Terminology Criteria for Adverse Events (CTCAE).
up to 2 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Pharmacokinetics of ASTX727 in solid tumor patients as measured by total exposure
Time Frame: Day 2
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)
Day 2
Pharmacokinetics of ASTX727 in solid tumor patients as measured by maximum concentration (Cmax)
Time Frame: Day 2
Cmax (mmol/L) is defined as the maximum concentration of ASTX727 in blood.
Day 2
Pharmacokinetics of ASTX727 in solid tumor patients as measured by time to maximum concentration (Tmax)
Time Frame: Day 2
Tmax (minutes) is defined as the time to reach maximum concentration of ASTX727 in blood.
Day 2
Objective response rate (ORR) in solid tumor patients who are treated with ASTX727
Time Frame: up to 2 years
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
up to 2 years
