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   43881   clinical trials with a EudraCT protocol, of which   7295   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.

    Sickle Cell Disease
    E.1.1.1Medical condition in easily understood language
    Sickle cell anaemia is a serious inherited blood disorder where the red blood cells, which carry oxygen around the body, develop abnormally and become rigid and shaped like a crescent (or sickle).
    E.1.1.2Therapeutic area Diseases [C] - Blood and lymphatic diseases [C15]
    MedDRA Classification
    E.1.2 Medical condition or disease under investigation
    E.1.2Version 21.0
    E.1.2Level PT
    E.1.2Classification code 10040644
    E.1.2Term Sickle cell disease
    E.1.2System Organ Class 10010331 - Congenital, familial and genetic disorders
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective is to assess the efficacy of GBT440 in adolescents and adults with Sickle Cell Disease (SCD) as measured by improvement in anemia.
    E.2.2Secondary objectives of the trial
    The secondary objectives are to evaluate the effects of GBT440 compared to placebo on SCD symptom exacerbation and TSS from PRO measurement, measures of anemia and hemolysis, and other clinical measures (e.g., VOC, ACS, hospitalization, RBC transfusions, opioid use).
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    All participants must meet the following inclusion criteria:
    1. Male or female study participants with Sickle Cell Disease:
    • Documentation of SCD genotype (HbSS, HbSC, HbSβ thalassemia or other sickle cell syndrome variants) may be based on history of laboratory testing or must be confirmed by
    laboratory testing during screening
    2. Participants have had at least 1 episode of VOC in the past 12 months. For study eligibility, VOC is defined as a previously documented episode of ACS or acute painful crisis (for which there was no explanation other than VOC) which required prescription or healthcare professional-instructed use of analgesics for moderate to severe pain (documentation must exist in the patient medical record prior to Screening)
    3. Age 12 to 65 years
    4. Hemoglobin (Hb) ≥5.5 and ≤10.5 g/dL during screening
    5. For participants taking hydroxyurea (HU), the dose of HU (mg/kg) must be stable for at least 90 days prior to signing the ICF and with no anticipated need for dose adjustments or initiation during the study, in the opinion of the Investigator
    6. Participants must demonstrate 75% compliance with ePRO measure completion to be randomised (participants will be given an ePRO device for at least 28 days during Screening; participants who have <75% compliance may be rescreened up to two times for PRO compliance.
    7. Participants, who if female and of child bearing potential, are using highly effective methods of contraception from study start to 30 days after the last dose of study drug, and who if male are willing to use barrier methods of contraception, from study start to 3 months after the last dose of study drug
    8. Participant has provided documented informed consent or assent (the informed consent form [ICF] must be reviewed and signed by each participant; in the case of pediatric participants, both the consent of the participant’s legal representative or legal guardian, and the participant’s assent must be obtained)
    E.4Principal exclusion criteria
    Any participant who meets one or more of the following criteria will be excluded from participation:
    1. More than 10 VOCs within the past 12 months that required a hospital, or emergency room or clinic visit
    2. Female who is breast feeding or pregnant
    3. Patients who are receiving regularly scheduled blood (RBC) transfusion therapy (also termed chronic, prophylactic, or preventive transfusion) or have received a RBC transfusion for any reason within 60 days of signing the ICF or at any time during the screening period.
    4. Hospitalized for sickle cell crisis or other vaso-occlusive event within 14 days prior to signing the ICF
    (i.e., a vaso-occlusive event cannot be within 14 days prior to ICF)
    5. Hepatic dysfunction characterized by alanine aminotransferase (ALT) >4 × ULN
    6. Participants with clinically significant bacterial, fungal, parasitic or viral infection which require therapy:
    • Participants with acute bacterial infection requiring antibiotic use should delay screening/enrollment until the course of antibiotic therapy has been completed.
    • Participants with known active hepatitis A, B, or C or who are known to be human immunodeficiency virus (HIV) positive
    7. Severe renal dysfunction (estimated glomerular filtration rate at the Screening visit; calculated by the central laboratory) <30mL/min/1.732 or on chronic dialysis
    8. History of malignancy within the past 2 years prior to treatment Day 1 requiring chemotherapy and/or radiation (with the exception of local therapy for non-melanoma skin malignancy)
    9. History of unstable or deteriorating cardiac or pulmonary disease within 6 months prior to consent including but not limited to the following:
    • Unstable angina pectoris or myocardial infarction or elective coronary intervention
    • Congestive heart failure requiring hospitalization
    • Uncontrolled clinically significant arrhythmias
    10. Any condition affecting drug absorption, such as major surgery involving the stomach or small intestine (prior cholecystectomy is acceptable)
    11. Participated in another clinical trial of an investigational agent (or medical device) within 30 days or 5 half-lives of date of informed consent, whichever is longer, or is currently participating in another trial of an investigational agent (or medical device)
    12. Inadequate venous access as determined by the Investigator/site staff
    13. Medical, psychological, or behavioral conditions, which, in the opinion of the Investigator, may preclude safe participation, confound study interpretation, interfere with compliance, or preclude informed consent
    14. Receipt of erythropoietin or other hematopoietic growth factors within 28 days of signing ICF or anticipated need for such agents during the study.
    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy measure is Hb response., defined as increase of Hb from baseline by > 1 g/dL at 24 weeks. Hb at 24 weeks is determined by the average value of Hb levels at Week 20 and Week 24.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Day 1, Weeks 2,4,6,8,12,16,20,24,36,48,60,72, EOS(+4weeks)
    E.5.2Secondary end point(s)
    The secondary efficacy endpoints are as follows:
    · Change from baseline in hemoglobin at Week 24
    · Change and percent change from baseline in hemolysis measures, including unconjugated bilirubin, absolute reticulocyte, reticulocytes %, and LDH at Week 24
    · Incidence of severe anemic episodes (Hb < 5.5 g/dL)
    · Annualized incidence rate of VOC
