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   44364   clinical trials with a EudraCT protocol, of which   7388   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 ).

    ECOG performance status
    Eastern Cooperative Oncology Group (ECOG) performance status scale is a widely used standard of care criteria used to assess the functional status of a patient with cancer to measure how the disease impacts thepatient’s daily living abilities. This scale has a range from 0 - 5. The higher the grade, the worse the patient's abilities: 0 implies fully active, able to carry on all pre-disease performance without restriction and 5 implies death.

    Body surface area (BSA)
    BSA is a measurement of the total area of the skin of a human body, usually expressed in square meters (m²). It's a crucial parameter in various medical calculations, including drug dosages, fluid administration, and determining metabolic mass. BSA (m^2) at baseline is calculated as square root of (weight (kg) * height (cm)/3600) using weight at baseline and height at screening.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    10 Feb 2020
    This amendment, issued before trial initiation and treatment, incorporated US FDA recommendations from the End of Phase 1 meeting (22 November 2019). The main objectives were to further evaluate subject safety during the safety run-in part of the trial by exploring a lower dose level of MBG453 (400 mg Q4W) with azacitidine and venetoclax before escalating to 800 mg Q4W, and to and to ensure consistency in the enrolled subject population across sites by modifying I/E criteria to more precisely define the population not suitable for intensive chemotherapy. As the combination of MBG453, azacitidine & venetoclax had not been tested in the clinic, the safety run-in initially enrolled a cohort of 3–6 evaluable subjects at a starting dose of MBG453 of 400 mg Q4W in combination with azacitidine and venetoclax; if tolerated, about 12 subjects were treated at the higher dose of MBG453 800 mg Q4W with same combination. Eligibility criteria were refined from the original protocol for uniformity, specifying age and certain comorbidities (cardiac, pulmonary, hepatic, renal) for patient selection, aligning with similar venetoclax studies. The modified definition of the secondary endpoint, event free survival (EFS) was modified per FDA feedback & was to be aligned with other MBG453 studies as well as with studies with other agents in this subject population. The modified definition of EFS now included treatment failure which is failure to achieve CR after 7 cycles of treatment, death due to any cause, and relapse from CR as events; disease progression and start of new therapy were no longer considered events. A new exploratory objective, Progression free survival (PFS) was added to evaluate the potential benefit of disease stabilization. Finally, clarification was provided on the scope of the Steering Committee (including recommendation of study termination). This amendment also included minor editorial changes and additional clarifications to address investigators’ questions.
    19 May 2020
    As the release of this amendment, no sites have been initiated, and no subject has been screened or has received study treatment in this trial. The main purpose of this amendment is to allow enrollment of patients receiving moderate or strong CYP3A4 inhibitors or Pg-p inhibitors, in order to allow use of prophylactic antifungal medications (e.g. posaconazole, fluconazole or other azoles) commonly used in this patient population. This amendment expands the pool of eligible subjects, allowing enrollment of subjects more representative of the overall population with AML not suitable for intensive chemotherapy. Venetoclax is metabolized via the CYP3A4 system. Inhibitors of CYP3A4 administered concurrently with venetoclax result in higher, potentially toxic plasma levels of venetoclax. This has been studied extensively and is reflected in the prescribing information for venetoclax. It is allowed to co-administer venetoclax with strong CYP3A inhibitors, but venetoclax doses need to be reduced. As many antifungal drugs commonly used for prophylaxis or treatment of fungal infections in AML are strong CYP3A inhibitors, this amendment removes the strict ban of co-administration in lieu of dose-reduction rules for venetoclax. In addition, the following updates have been implemented: Extend the restrictions on the use of live vaccines until the end of the follow-up period after the last dose of MBG453; Guidance has been added on the criteria for MBG453 dose management for dermatological adverse drug reactions (ADRs) and non-immune related toxicities to align with the MBG453 Investigator’s Brochure; Guidance has been added that subjects should be monitored carefully for any skin toxicity or mucositis, and that study treatment should be discontinued for any suspected case of Stevens-Johnson syndrome (SJS), or Lyell syndrome/toxic epidermal necrolysis (TEN) to align with the MBG453 Investigator’s Brochure.

    At the time of release of this amendment, 5 subjects have been enrolled to this trial. The main purpose of this amendment is to modify the exclusion criteria to permit enrollment of patients with therapy-related AML. This change will align eligibility criteria with VIALE-A, the Phase III study that demonstrated the efficacy of venetoclax and azacitidine in patients with AML not suitable for intensive chemotherapy. In addition, the following notable changes were made: - Exclusion criterion #6 was modified to allow enrollment of patients who have been treated for a malignancy and have been disease free (absence of residual disease) for at least 1 year; previously a disease free period of 2 years was required. - Requirements for evaluation of extramedullary disease were modified to allow imaging modalities and techniques to be selected based on institutional standard of care. The previous specifications for use of CT scan or MRI have been removed. - Venetoclax ramp-up dosing was updated based on Venclexta® (Venetoclax) USPI 2018. The 4-day ramp-up dosing was amended to 100 mg (D1), 200 mg (D2), 400 mg (D3), 400 mg (D4) compared to the original protocol which noted 4-day ramp-up dosing as 100 mg (D1), 200 mg (D2), 300 mg (D3), 400 mg (D4). - New, Novartis standard language, referred to as disruption proofing language, has been added to address trial conduct during public health emergencies. The added language addresses study participant safety and trial integrity. In addition, updates to the new version of Novartis protocol CTP template were made. - This amendment also includes minor editorial changes and additional clarifications

    At the time of release of this amendment, 29 subjects have been enrolled to this trial. Part 1 (safety run-in) has been completed, and following investigator’s recommendation from the Safety Review Meeting held on 26-Oct-2021, the expansion phase has opened to enrollment. The main purpose of this amendment is to modify the guidance on permanent discontinuation of treatment for patients experiencing prolonged cytopenias. Cytopenia is a common adverse event with the triplet combination of MBG453, venetoclax, and azacitidine and may take longer than 28 days to recover. For patients experiencing prolonged cytopenias, the study treatment may be interrupted for up to 42 days. This change will allow patients the opportunity to stay on study treatment while their blood counts recover. In addition, the DLT criteria related to prolonged hematologic toxicities, applicable during the safety run-in phase, were modified. A CTCAE Grade 4 neutropenia, thrombopenia or pancytopenia, not related to leukemic infiltration, persisting beyond 42 days (instead of 56 days previously) from start of treatment cycle constitutes a DLT. This change was implemented consistently for pertinent combination studies within the MBG453 program.
    08 Dec 2022
    At the time of release of this amendment, all subjects (n= 90) have been enrolled to this trial. The main purpose of the present amendment is to revise the timing of the primary analysis (CR analysis) in order to capture potential late responders and more robust duration of response to study treatment. The CR rate analysis, initially planned when all subjects completed at least 7 treatment cycles or discontinued earlier, will now be performed when all subjects completed at least 12 treatment cycles or discontinued earlier. As recent publications highlighted the high variability of time to/duration of response in patients receiving venetoclax plus azacitidine; it is necessary to allow sufficient follow-up time before conducting the CR rate analysis. In addition, the following secondary endpoints were added: CR/CRh rate and duration of CR/CRh that will be derived by the Sponsor. These changes are made to reflect the updated ELN 2022 diagnosis and management of AML guidelines.
