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   44378   clinical trials with a EudraCT protocol, of which   7390   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 ).

    General information about the trial
    Main objective of the trial
    Myelofibrosis is a type of bone marrow cancer that usually develops slowly and disrupts body's normal production of blood cells. It causes bone marrow scarring, leading to severe anemia that can cause weakness and fatigue. It can also cause a low number of blood-clotting cells called platelets, which increases risk of bleeding. Myelofibrosis often causes an enlarged spleen. The purpose of this study is to see if a combination of navitoclax and ruxolitinib is more effective and safe in assessment of change in spleen volume when compared to ruxolitinib in participants with myelofibrosis. Participants will receive oral navitoclax tablet with oral ruxolitinib tablet or oral ruxolitinib tablet with oral placebo (no active drug) tablet and treatment may continue until the participant cannot tolerate the study drug, or benefit is not achieved, or other reasons which qualify for discontinuation of the study drug.
    Protection of trial subjects
    Subjects must voluntarily sign and date an informed consent (or their legally authorized representative can sign and date the informed consent upon subject's understanding of the consent, if permitted by local regulations), approved by an independent ethics committee (IEC)/institutional review board (IRB) prior to the initiation of any Screening or study-specific procedures.

    Placebo for Navitoclax + Ruxolitinib
    Arm description
    Placebo for navitoclax tablets were administered orally once daily (QD) per Baseline platelet count (>150 × 10^9/L starting dose of 200 mg; ≤150 × 10^9/L starting dose of 100 mg, which could be increased to 200 mg QD after 7 days provided platelet count is ≥75 × 10^9/L). Placebo for navitoclax didn’t exceed 200 mg QD for first 24 weeks of treatment. After Week 25, Day 1 visit, placebo for navitoclax dose may be increased to 300 mg QD at Investigator’s discretion for those with suboptimal spleen response defined as failure to achieve spleen volume reduction of at least 10% per imaging. Ruxolitinib tablets were administered orally twice daily (BID) per Baseline platelet count (>200 × 10^9/L starting dose of 20 mg; 100-200 × 10^9/L starting dose of 15 mg). Participants will continue their treatment until end of clinical benefit, unacceptable toxicity, or they meet other protocol criteria for discontinuation (whichever occurs first).

    Change From Baseline in Total Symptom Score (TSS) at Week 24 as Measured by Myelofibrosis Symptom Assessment Form (MFSAF) v4.0
    End point description
    TSS is assessed by the Myelofibrosis Symptom Assessment Form (MFSAF) version 4.0. Participants complete a symptom diary and rate the following seven MF symptoms: fatigue, night sweats, abdominal discomfort, pruritus, pain under the ribs on the left side, early satiety, and bone pain daily using a scale from 0 (absent) to 10 (worst imaginable), and the scores are averaged over 7 days, with a minimum of 4 days required to calculate the average score. Participants for whom a valid average score cannot be calculated either at baseline or post-baseline are considered non-responders. The TSS reflects the sum of the scores of these symptoms, for a maximum possible score of 70 (i.e., most severe symptom experience). Negative changes from Baseline indicate improvement.

    Placebo for navitoclax tablets were administered orally once daily (QD) per Baseline platelet count (>150 × 10^9/L starting dose of 200 mg; ≤150 × 10^9/L starting dose of 100 mg, which could be increased to 200 mg QD after 7 days provided platelet count is ≥75 × 10^9/L). Placebo for navitoclax didn’t exceed 200 mg QD for first 24 weeks of treatment. After Week 25, Day 1 visit, placebo for navitoclax dose may be increased to 300 mg QD at Investigator’s discretion for those with suboptimal spleen response defined as failure to achieve spleen volume reduction of at least 10% per imaging. Ruxolitinib tablets were administered orally twice daily (BID) per Baseline platelet count (>200 × 10^9/L starting dose of 20 mg; 100-200 × 10^9/L starting dose of 15 mg). Participants will continue their treatment until end of clinical benefit, unacceptable toxicity, or they meet other protocol criteria for discontinuation (whichever occurs first).

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    24 Jun 2020
    Protocol Version 2.0 Efficacy endpoints were updated. The study design was amended to double-blind with placebo to match navitoclax. Subjects classified as intermediate-1 by DIPSS+ were excluded from the study. Optional lead-in phase was added. Dose adjustment guidelines were updated per ruxolitinib label. Updated dose adjustment guidelines for thrombocytopenia for platelet counts ≥ 100 x 10^9 /L to < 125 x 10^9 /L and counts ≥ 75 x 10^9 /L to < 100 x 10^9 /L.
    05 Nov 2020
    Protocol Version 3.0 Clarification of endpoints was added. PK sampling was updated. Eligibility criteria were clarified for subjects ineligible for stem cell transplantation, subjects with an undetectable viral load, and subjects with serologic evidence of prior vaccination to HBV. Added additional hematologic samples. Statistical analyses were updated to add definition of secondary endpoints, handling of missing data, and sequence of testing for key secondary endpoints. Additional text was added to clarify that the investigator may adjust the starting dose of ruxolitinib as medically appropriate after consultation with the TA MD/SD with subsequent increase in dose as directed in the protocol. Prohibited/cautionary medications and therapy was updated regarding disulfiram, hydroxyurea, JAK inhibitors, treatments with interferon, erythropoietin, danazol, and steroids and clarified the local approved ruxolitinib product label should be referenced when coadministering with CYP3A inducers or drugs transported by P-glycoprotein and BCRP, for monitoring and dose adjustment for all hematological and non-hematological toxicities, and for dose adjustment of subjects with hepatic or renal impairment. Updated toxicity management to clarify the local approved product label for ruxolitinib should be referenced for monitoring and dose adjustment guidelines for all hematological and non-hematological toxicities in addition to the dose modification guidelines provided. Updated dose adjustment guidelines for thrombocytopenia for platelet counts ≥ 125 x 10^9 /L. Clarification was added that the study will be monitored by an IDMC.
    27 May 2021
    Protocol Version 4.0 Intermediate dose levels for navitoclax were added. MRI contraindication of severe anxiety and claustrophobia was added and CT scans were allowed. Ferritin was added to clinical laboratory tests. TB test at screening was clarified. Toxicity management taper verbiage was added for subjects who are at increased risk of exacerbation of splenomegaly and other significant symptoms. CT scan was allowed for MRI contraindication of severe anxiety and claustrophobia. Updated toxicity management taper verbiage for subjects who are at increased risk for exacerbation of splenomegaly and other significant symptoms. With abrupt interruption of ruxolitinib, exacerbation of disease is reported in the literature. This will enable gradual taper and interruption to minimize the risk and address the investigators' concern. Added intermediate dose levels for navitoclax. These are incorporated in this protocol for consistency across the clinical studies to minimize significant dose reductions, dose interruptions and enable appropriate dosing for subjects who experience thrombocytopenia.
    03 Feb 2022
    Protocol Version 5.0 Additional clarification on the interpretation of subject ineligible for stem cell transplantation in eligibility criteria was provided. PROs procedure on Week 1 Day 1 was clarified. Rescreening of screen-failed subjects was clarified. Updated navitoclax dose adjustment to no change or increase dose for platelet counts ≥ 125 x 10^9 /L to align with dose adjustment instructions. Navitoclax/placebo dose adjustment was aligned throughout the protocol.
    31 Mar 2022
    Protocol Version 6.0 Requirement on completing and the score calculation for MFSAF was clarified. Navitoclax/placebo dose adjustment guidelines was updated for thrombocytopenia and neutropenia to clarify action for navitoclax/placebo. MFSAF TSS calculation and symptom response assessment were updated.
    23 Mar 2023
    Protocol Version 7.0 Secondary and exploratory efficacy endpoints were updated. Continuation of study treatment for subjects with disease progression and relapse was clarified. Stratification factors were clarified.
