Study of Orally Administered CA-4948(IRAK4i) as a Monotherapy in patients with Acute Myelogenous Leukemia or Myelodysplastic Syndrome
EU CTIS ID: 2024-513313-13-00
What this study is testing
Phase 1 To evaluate the safety and tolerability of CA-4948 in patients with relapsed / refractory (R/R) acute myelogenous leukemia (AML) and higher-risk myelodysplastic syndrome (hrMDS) To identify maximum tolerated dose (MTD) and recommended Phase 2 Dose (RP2D) Phase 2a: To assess anti-cancer activity of CA-4948 at RP2D in patients with R/R AML with FMS-like tyrosine kinase-3 (FLT-3) mutations, and patients with R/R hrMDS or R/R AML with spliceosome mutations of SF3B1 or U2AF1

Who can take part
You may be able to join if
- 01. Males and females >=18 years of age
- 09. Negative serum pregnancy test in women of childbearing potential (WOCP)
- 10. WOCP and men who partner with a WOCP must agree to use highly effective contraceptive methods for the duration of the study and for 180 days after the last dose of CA-4948
- 11. Willing and able to provide written informed consent and comply with the requirements of the study
- 12. Biopsy requirement for AML and MDS: patients must be willing to have serial bone marrow sampling and peripheral blood sampling during the study. The diagnosis and evaluation of AML and MDS will be made by bone marrow aspiration and/or biopsy. If an aspirate is unobtainable (ie, a “dry tap”), the diagnosis is made from the core biopsy.
- 02. Life expectancy of at least 3 months
You likely can't join if
- 01. Diagnosed with acute promyelocytic leukemia (APL, M3)
- 10. Patients with active advanced malignant solid tumors
- 11. Viral Infections: a. Known to be human immunodeficiency virus (HIV) positive or have an acquired immunodeficiency syndrome-related illness. If HIV virus is undetectable and maintained on treatment, enrollment may be allowed after discussion with the Sponsor b. Hepatitis B virus (HBV) DNA positive or hepatitis C virus (HCV) infection < 6 months prior to start of CA-4948 unless viral load is undetectable, or HCV with cirrhosis Note: testing only required in patients with history of HBV or history of HCV < 6 months prior to start of CA-4948.
- 12. Concomitant illnesses that would preclude safe participation in study, identified within approximately 28 days of C1D1, including: a. Uncontrolled or severe cardiovascular disease, including myocardial infarction or unstable angina within 6 months prior to CA-4948, New York Heart Association Class II or greater congestive heart failure, or left ventricular ejection fraction < 50% by echocardiogram or multi-gated acquisition scan, serious arrhythmias uncontrolled on treatment, clinically significant pericardial disease, cardiac amyloidosis, congenital long QT syndrome, or QTc with Fridericia’s correction (QTcF) that is unmeasurable or > 450 msec on Screening electrocardiogram (ECG) Note: for QTcF > 450 msec on the Screening ECG, the ECG may be repeated twice at least 24 hours apart; the mean QTcF from the 3 Screening ECGs must be ≤ 450 msec in order to meet eligibility for study participation. Patients with bundle branch block and/or ventricular paced rhythms should be reviewed by the Medical Monitor for potential inclusion. b. Gastrointestinal disease or disorder that could interfere with the swallowing, oral absorption, or tolerance of CA-4948. This includes major abdominal surgery and/or significant bowel resection and/or gastrointestinal diseases that could alter the assessment of PK or safety c. Any other severe, acute, or chronic medical, psychiatric or social condition, or laboratory abnormality that may increase the risk of study participation or CA-4948 administration, may interfere with the informed consent process and/or with compliance with the requirements of the study or may interfere with the interpretation of the study results and, in the Investigator's opinion, would make the patient inappropriate for entry into this study d. Systemic fungal, bacterial, viral, or other infection that is not controlled (defined as exhibiting ongoing signs/symptoms related to the infection and without improvement, despite appropriate antibiotics or other treatment)
- 13. Pregnant or lactating
- 14. History of ≥ Grade 3 rhabdomyolysis without complete recovery
