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 and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  1. Subjects must be ≥ 18 years of age.
  2. Subjects must have R/R AML
  3. Subjects must have documented IDH1 R132 gene-mutated based on the central evaluation.
  4. Subjects must have ECOG PS of 0 to 2.
  5. Subjects must be amenable to serial bone marrow sampling and peripheral blood samplings during the study.
  6. Subjects must have adequate hepatic function as evidenced by Serum total bilirubin ≤ 1.5 × upper limit of normal (ULN), unless considered due to Gilbert's disease or leukemic involvement and Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) ≤ 3.0 × ULN, unless considered due to leukemic involvement.
  7. Subjects must have an adequate renal function as evidenced by Serum creatinine ≤ 2.0 × ULN or Creatinine clearance >40 mL/min based on the Cockcroft-Gault glomerular filtration rate (GFR) estimation.
  8. Subjects must be recovered from any clinically relevant toxic effects of any prior surgery, radiotherapy, or other therapy intended for the treatment of cancer.

Exclusion Criteria:

  1. Subjects who previously received prior treatment with a mutant-specific IDH1 inhibitor and progressed on therapy.
  2. Subjects who have undergone HSCT within 60 days of the first dose of ivosidenib, or subjects on immunosuppressive therapy post HSCT at the time of screening, or with clinically significant graft-versus-host disease (GVHD).
  3. Subjects who received systemic anticancer therapy or radiotherapy < 14 days prior to their first day of ivosidenib administration. Hydroxyurea and leukapheresis are allowed prior to enrollment and after the start of ivosidenib for the control of leukocytosis to reduce peripheral leukemic blasts.
  4. Subjects who received an investigational agent < 14 days prior to their first day of study drug administration.

  6. Subjects for whom potentially curative anticancer therapy is available.
  7. Subjects with an active severe infection that required anti-infective therapy or with an unexplained fever > 38.5°C during screening visits or on their first day of study drug administration (at the discretion of the Investigator, subjects with tumor fever may be enrolled).7. Subjects who are pregnant or breastfeeding.
  8. Subjects with New York Heart Association (NYHA) Class III or IV congestive heart failure or LVEF < 40% by an echocardiogram (ECHO) or multi-gated acquisition (MUGA) scan obtained within approximately 28 days of C1D1.
  9. Subjects with a history of myocardial infarction within the last 6 months of screening.
  10. Subjects with known unstable or uncontrolled angina pectoris.
  11. Subjects with a known history of severe and/or uncontrolled ventricular arrhythmias.
  12. Subjects with known dysphagia, short-gut syndrome, gastroparesis, or other conditions that limit the ingestion or gastrointestinal absorption of drugs administered orally.
  13. Subjects with clinical symptoms suggesting active central nervous system (CNS) leukemia or known CNS leukemia. Evaluation of cerebrospinal fluid is only required if there is a clinical suspicion of CNS involvement by leukemia during screening.
  14. Subjects with immediately life-threatening, severe complications of leukemia such as uncontrolled bleeding, pneumonia with hypoxia or shock, and/or disseminated intravascular coagulation.
  15. Subjects with a known medical history of progressive multifocal leukoencephalopathy.

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

EXPERIMENTAL: Ivosidenib (CS3010) tablet
Drug: ivosidenib
subjects will receive a single dose of ivosidenib 500 mg on Day -3 (i.e., 3 days prior to the start of daily dosing) and undergo PK/PD assessments over 72 hours to evaluate drug concentrations and 2-HG levels. Following that, subjects will be treated with ivosidenib 500 mg once a day (QD) PO continuously (28-day cycles, there are no inter-cycle rest periods).
