Summary

Study ASTX030-01 is designed to move efficiently from Phase 1 to Phase 3. Phase 1 consists of an open-label Dose Escalation Stage (Stage A) using multiple cohorts at escalating dose levels of oral cedazuridine and azacitidine (only one study drug will be escalated at a time) followed by a Dose Expansion Stage (Stage B) of ASTX030. Phase 2 is a randomized open-label crossover study to compare oral ASTX030 to subcutaneous (SC) azacitidine. Phase 3 is a randomized open-label crossover study comparing the final oral ASTX030 dose to SC azacitidine. The duration of the study is expected to be approximately 48 months.

Eligibility

Yes No Not Sure

Inclusion Criteria

Confirmed MDS, CMML, MDS/MPN, or AML who are candidates to receive and benefit from single agent azacitidine as follows and as applicable according to local country approvals and/or local institution standard practice
French-American-British myelodysplastic syndrome subtypes: refractory anemia (RA) or refractory anemia with ringed sideroblasts (if accompanied by neutropenia or thrombocytopenia or requiring transfusions), refractory anemia with excess blasts (RAEB), refractory anemia with excess blasts in transformation (RAEB-T), or MDS with intermediate-2 or high risk MDS according to the International Prognostic Scoring System (IPSS). MDS/MPN patients including CMML according to the World Health Organization (WHO) 2016 classification are also eligible if they are candidates to receive single agent azacitidine per local institution standards; or
Previously untreated AML with 20% to 30% blasts present in bone marrow and multi-lineage dysplasia (Phase 2 and 3 only); or
Previously untreated AML with >30% blasts present in bone marrow, who are not eligible for stem cell transplant and unfit for intensive chemotherapy induction (Phase 2 and 3 only)
Participants with Eastern Cooperative Oncology Group (ECOG) performance status of 0 to
\
Participants with adequate organ function defined as
Hepatic: Total or direct bilirubin ≤2 × upper limit of normal (ULN); aspartate aminotransferase (AST)/serum glutamic-oxaloacetic transaminase (SGOT) and alanine aminotransferase (ALT)/serum glutamic pyruvic transaminase (SGPT) ≤2.5 × ULN
Renal: Calculated creatinine clearance >50 mL/min/1.73 m^2 by Cockcroft-Gault formula or other medically acceptable formulas
Participants with no major surgery within 2 weeks before first study treatment
For participants with prior allogeneic stem cell transplant, no evidence of
Participants with no cytotoxic chemotherapy within 4 weeks before first study treatment
graft-versus-host disease (GVHD) and must be ≥2 weeks off systemic
immunosuppressive therapy before start of study treatment
Participants with projected life expectancy of at least 12 weeks
Women of child-bearing potential (according to recommendations of the Clinical Trial Facilitation Group) must not be pregnant or breastfeeding and must have a negative pregnancy test at screening
Able to swallow the number of tablets/capsules required for the treatment assignment within a 10-minute period and tolerate 4 hours of fasting

Exclusion Criteria

Active uncontrolled gastric or duodenal ulcer
Poor medical risk because of other conditions such as uncontrolled systemic diseases or active uncontrolled bacterial, viral, or fungal infections
Life-threatening illness (e.g., uncontrolled bleeding and patients at risk for or are experiencing leukostasis [AML]), uncontrolled medical condition or organ system dysfunction, or other reasons, which, in the investigator's opinion, could compromise the participant's safety, interfere with the absorption or metabolism of oral cedazuridine + azacitidine or compromise the integrity of the study outcomes
Prior malignancy, except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, prostate cancer or breast cancer under control with hormone therapy, or other cancer from which the participant has been disease free for at least 2 years
Participants with MDS/MPN who have clinical extramedullary disease including clinically palpable hepatomegaly or splenomegaly
Previous treatment with more than 1 cycles of decitabine, azacitidine, or guadecitabine (Phases 2 and 3 only)
Treated with any investigational drug or therapy within 2 weeks, or 5 half lives, whichever is longer, before the protocol-defined first dose of study treatment, or ongoing clinically significant adverse events from previous treatment with investigational drug or therapy
Known or suspected hypersensitivity to cedazuridine or azacitidine, or any of their excipients
