A Study of ASTX727 in People With Malignant Peripheral Nerve Sheath Tumors (MPNST)
What this study is about
The purpose of this study is to see whether the study drug ASTX727 is an effective treatment for people who have MPNST with a PCR2 mutation. ASTX727 is a combination of two drugs (cedazuridine and decitabine) that have been designed to target cancer cells with a PCR2 mutation and to disrupt the cells' ability to survive and grow.
View original scientific description
The purpose of this study is to see whether the study drug ASTX727 is an effective treatment for people who have MPNST with a PCR2 mutation. ASTX727 is a combination of two drugs (cedazuridine and decitabine) that have been designed to target cancer cells with a PCR2 mutation and to disrupt the cells' ability to survive and grow. The study researchers think that the study drug allows decitabine to work better than decitabine given alone.
Interventions
DRUG
ASTX727
ASTX727 will be self-administered orally by the patient on a once daily basis, days 1 through 5 of each 21-day cycle. Cycle 1 day 1 (C1D1) is defined as the first day that ASTX727 is administered.
Primary outcome measures
the best clinical benefit rate (CBR)
Time frame: at the end of 16 weeks
(complete response \[CR\] + partial response \[PR\] + stable disease \[SD\]) by RECIST1.1
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Patients must have pathologically confirmed PRC2 loss MPNSTs (e.g. IHC of loss H3K27me2 and/or H3K27me3 immunostaining, and/or inactivating mutations in EED, SUZ12, EZH2 by CLIA approved genetic assays), which are advanced, unresectable or metastatic and have progressed on at least one line of standard of care systemic therapy, or administration of cytotoxic chemotherapy is not considered in the best interest for the patient.
- Patients must be at least 18 years of age
- Patients must have Eastern Cooperative Oncology Group (ECOG) performance status of ≤2.
- Disease must be measurable by RECIST 1.1.
- Patients must be able to take oral medications.
- Patient or legally authorized representative can understand and comply with the protocol and must sign an informed consent document.
- Adequate renal, hepatic and hematologic function as the following: serum creatinine ≤ 1.5 x upper limit of normal (ULN), total serum bilirubin ≤ 1.5 x ULN, serum AST (SGOT) ≤ 2.5 x UL

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
