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   43861   clinical trials with a EudraCT protocol, of which   7284   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 ).

    End point description
    An adverse event (AE) was any untoward medical occurrence in a subject who received study drug (MEDI-551). A serious adverse event (SAE) was an AE resulting in any of these outcomes: death; initial or prolonged inpatient hospitalization; life-threatening experience; persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between use of study drug and Day 90 that were absent before treatment or that worsened relative to pre-treatment state. An AESIs was one of scientific and medical interest specific to understanding of study product and may have required close monitoring and rapid communication by investigator to the sponsor. Treatment emergent AESIs were collected from the time of dosing through Day 90 after the last dose of study drug. Hepatic function abnormality and infusion reactions resulting in discontinuation were considered as AESIs in this study. The safety population includes all subjects who received any investigational product.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    17 Jan 2012
    - The bendamustine dose used in another CLL study was corrected from 90 mg/m^2 to 70 mg/m^2 - Inclusion Criterion were revised from stating study subjects must be eligible for chemotherapy to stating that study subjects must be eligible for bendamustine/rituximab therapy to be included in the study - Inclusion Criterion for description of symptomatic disease was expanded to include enlarging adenopathy and increasing cytopenias. The additional indications were added in accordance with the diagnostic, treatment and response criteria in Hallek et al, 2008. - Exclusion Criterion for describing excluded prior therapies was removed to correctly state the intention of the sponsor to permit any prior therapy. - Exclusion Criterion was added to exclude any subject who had exposure to bendamustine within 180 days before study enrollment. There is a high likelihood that patients who have received bendamustine in the last 180 days are resistant to it; therefore it is unethical to provide the same therapy - The lists of acceptable treatments for infusion reactions and for pretreatment of subjects who experienced infusion reactions were revised. In addition to acetaminophen and antihistamines, corticosteroids are permitted. Steroids are considered standard, acceptable adjunctive treatments for infusion reactions. - The listed procedure of MEDI-551 PK sample was revised to list pre-dose and post-dose samples separately to emphasize that pre-dose and post-dose samples must be taken on Day 1 of each cycle and on Day 8 of Cycle 1. - The procedure of pregnancy test (urine β hCG) and in visit descriptions was revised to include the restriction to women of childbearing potential. This was done as an aid to the investigator staff and to avoid needless testing. - Information about the composition and operation of the study DMC was revised to reflect the current plan.

    Exploratory objective changed from, “To conduct exploratory pharmacogenomic analyses” to “To examine the association of FcγR polymorphisms with MEDI-551 treatment effects and complete elimination of minimal residual disease. Clarified primary endpoint ORR, is defined as the proportion of subjects with CR or PR according to the International Workshop on Chronic Lymphocytic Leukemia’s update of the National Cancer Institute - Working Group 1996 guidelines on CLL. The dosing section updated with Phase 1 protocol MI-CP204 results. Changes to inclusion criteria: Eligible subjects must have had a minimum of one course of chemotherapy with rituximab, because rituximab is considered the standard of care for CLL; Confirmation of CLL and presence of symptomatic disease defined in more detail; The definition of adequate hematological function criterion for absolute neutrophil count (ANC) was lowered from a minimum of 1,500/mm^3 to 1,000/mm^3; CLL is a disease that commonly presents with cytopenias resulting from disease-overloaded marrow with limited hematopoietic function; the majority of subjects present with ANC below 1500/mm3; Therefore, the ANC requirement has been lowered to permit increased access of study drug to subjects; Investigators are permitted to supplement subjects with GCSF at their discretion to minimize the duration of neutropenia so as to minimize the risk of infection; Serum creatinine limits modified to ≤ 1.5 mg/dL or calculated creatinine clearance ≥ 60 mL/minute as determined by the Cockcroft-Gault equation to provide limits more appropriate to this population. Changes to exclusion criteria: Subjects suspected of having Richter’s transformation or high-grade disease, current pregnancy or lactation and history of yellow fever vaccination; cautions regarding potential of interaction of bendamustine with CYP1A2 inhibitors and inducers of CYP1A2 were added; the DMC’s plan for recommendation for the dose selected (2 mg/kg or 4 mg/kg) was clarified.

    -All subjects were given oral acetaminophen & diphenhydramine methylprednisolone IV 30-60 min prior to first infusion of MEDI-551 was added. -MEDI-551/rituximab on Day2 of Cycle1,followed by 2nd dose of bendamustine. -Prophylaxis before rituximab infusion was at investigator’s discretion added. -Potential risks of MEDI-551 were updated. 3 exploratory objectives were added -Inclusion Criteria •Recovered from any acute side effects resulting from previous anticancer therapy was removed. •Hemoglobin & platelet count lowered to ≥8g/dL & ≥50000/mm^3. Alternative hemoglobin level & platelet count were eliminated for simplify entry requirements. •Adequate organ function was revised: bilirubin level revised from <2mg/dL to <2×ULN, calculated creatinine clearance lowered to ≥50 mL/min. •Use of birth control after study drug was extend beyond 90 days. •Duration of contraception was modified to at least Day1 through 90 days after the last dose of study drug. -Exclusion Criteria •Was changed to History of Grade 4 anaphylactic reaction to any component of MEDI-551, rituximab/bendamustine formulations Grade of anaphylactic reaction was defined. •Exclusions related to hepatitis B&C was split into 2 exclusion criteria; Exclusion relates to hepatitis C. -Conditions were added to reasons for permanent discontinuation from study drug: •Grade 4 febrile neutropenia or sepsis, regardless of attribution & treatment arm. •Grade 3 or higher toxicity attributed to MEDI-551. •Delay in start of a cycle by greater than 7 days. •Grade 4 infusion reaction by MEDI-551. -Subjects received mandatory premedication before the first dose of MEDI-551 was restated. Other premedication was permitted as clinically indicated, or in accordance with institutional guidelines for administration of a MAb. -Prophylactic antibiotics allowed & recommended in subjects with medical history of recurrent or severe infections.” -The schedule of study procedures was updated -Futility analysis added.
    19 Oct 2015
    Details about Blinded central independent review was removed from rationale from “Study Design, dose and control group” as well as the section on Blinding. The following text was removed from the planned analysis section: “Two formal analyses are planned for the study. The first analysis will be performed once all subjects have discontinued from the study-specific chemoimmunotherapies. This will occur approximately 6 months post randomization of the last subject randomized into the study.”
