Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   44334   clinical trials with a EudraCT protocol, of which   7366   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Phase 2a:
    - To assess tolerability and long-term safety
    - To further assess anti-cancer activity of CA-4948 at RP2D
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Males and females >= 18 years of age
    2. Life expectancy of at least 3 months

    Phase 1 Dose Escalation
    . AML (primary or secondary, including treatment-related; European Leukemia Net category) after failing at least 1 standard treatment (may include chemotherapy, re induction therapy or SCT), based on the assessment of the Investigator.
    OR
    . Higher-risk R/R MDS (International Prognostic Scoring System-revised score >3.5; Pfeilstocker 2016) that are considered resistant/refractory following at least 2 to 3 cycles of hypomethylating agents, or evidence of early progression

    Patients that meet 1 of the following criteria:
    • R/R AML with FLT3 mutations who have been previously treated with a FLT3 inhibitor
    • R/R AML with spliceosome mutations of SF3B1 or U2AF1
    • R/R hrMDS (IPSS-R score > 3.5) with spliceosome mutations of SF3B1 or U2AF1
    And
    • Have had ≤ 2 lines of prior systemic anti-cancer treatment (see Appendix M for guidelines)

    Phase 2a Dose Expansion
    Patients with:
    • R/R AML with FLT3 mutations who have been previously treated with a FLT3 inhibitor
    • R/R AML with spliceosome mutations of SF3B1 or U2AF1
    • R/R hrMDS (IPSS-R score > 3.5) with spliceosome mutations of SF3B1 or U2AF1
    And
    • Have had ≤ 2 lines of prior systemic anti-cancer treatment (see Appendix M for guidelines)

    5. Acceptable organ function at Screening as described below:
    a. Estimated creatinine clearance (CrCl) of ≥ 35 mL/min (Appendix H).
    b. Aspartate aminotransferase or alanine aminotransferase ≤ 2 × ULN
    c. Total bilirubin ≤ 1.5 × ULN or ≤ 3 × ULN in patients with documented Gilbert’s syndrome
    d. White blood cell count ≤ 25,000/μL (hydroxyurea is allowed during Screening and Cycle 1 for cytoreduction, if needed, for patients with AML per Investigator’s discretion. However, hydroxyurea must stop prior to Cycle 2)
    6. CPK < Grade 2.
    7. For patients on a cholesterol lowering agent that has been associated with CPK elevations, such as statins or fibrates, the agent should be discontinued or replaced with an alternative if medically feasible. Otherwise, it should be reduced to the lowest dose that is biologically
    effective (ie, the lowest dose required to achieve the desired clinical effect).
    8. Ability to swallow and retain oral medications
    9. 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 trial
    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 (i.e., a “dry tap”), the diagnosis is made from the core biopsy
    E.4Principal exclusion criteria
    1. Diagnosed with acute promyelocytic leukemia (APL, M3)
    2. Known active central nervous system (CNS) leukemia; patients with previously treated CNS disease may participate if asymptomatic as determined by treating physician (without symptomatic active disease for at least 4 weeks prior to the first dose of treatment, and any neurologic symptoms have returned to baseline)
    3. Allogeneic SCT within 60 days of the first dose of CA-4948, or clinically significant graft-versus-host disease (GVHD) requiring ongoing up titration of immunosuppressive medications prior to start of CA-4948
    Note: The use of a stable or tapering dose of immunosuppressive therapy post-SCT and/or topical steroids for ongoing skin GVHD is permitted with Medical Monitor approval
    4. Chronic myelogenous leukemia
    5. Any prior systemic anti-cancer treatment such as chemotherapy, immunomodulatory drug therapy, etc., received within 3 weeks (or 5 half-lives), whichever is shorter, or radiotherapy received 2 weeks prior to the start of CA-4948
    Note: Localized radiation or surgical resection of skin cancers is allowed
    6. Use of any investigational agent within 3 weeks (or 5 half-lives), whichever is shorter, prior to start of CA-4948
    7. Presence of an acute or chronic toxicity resulting from prior anti-cancer therapy, with the exception of alopecia that has not resolved to Grade ≤1, as determined by NCI CTCAE v 4.03 within 7 days prior to start of CA 4948 unless approved by the Medical Monitor
    8. Known allergy or hypersensitivity to any component of the formulation of CA-4948 used in this study
    9. Major surgery, other than diagnostic surgery, <28 days from the start of CA-4948; minor surgery <14 days from the start of CA-4948
    Note: Insertion of a vascular access device is not considered minor surgery
    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, enrolment 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 sec on the Screening ECG, the ECG may be repeated twice at least 24 hours apart; the mean QTcF from the three screening ECGs must be ≤ 450 msec in order to meet eligibility for trial participation
    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
