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   43845   clinical trials with a EudraCT protocol, of which   7282   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 ).

    Recruitment
    Recruitment details
    		 This was an open-label, 2 arm study to evaluate the safety and clinical activity of GSK2879552 alone, or in combination with azacitidine in adult participants with myelodysplastic syndromes (MDS). The study was conducted in 3 centers among 2 countries.

    Pre-assignment
    Screening details
    		 Total 5 participants were included into Part 1 and received GSK2879552. The study was terminated during Part 1 and hence Part 2 was not conducted as the risk benefit in earlier studies do not favor continuation of this study.

    End point description
    An AE is any untoward medical occurrence in a clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Any untoward event resulting in death, life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, congenital anomaly/birth defect, any other situation according to medical or scientific judgment that may not be immediately life-threatening or result in death or hospitalization but may jeopardize the participant or may require medical or surgical intervention or event associated with liver injury and impaired liver function were categorized as SAE. An event was considered a DLT if it occurred within the first 28 days of treatment, and met the DLT criteria unless it could be clearly established that the event was unrelated to treatment.

    Blood samples were collected from participants for evaluation of hematology parameters including platelets, neutrophils, monocytes, lymphocytes, leucocyte, eosinophils and basophils. Baseline was defined as the value obtained prior to first dosing (Day 1). Change from Baseline was calculated by subtracting post-dose value from Baseline value. 99999 indicates data was not available as standard deviation could not be calculated due to insufficient number of participants. Only those participants with data available at the specified data points were analyzed (represented by n= X in the category titles).

    Blood samples were collected from participants for evaluation of clinical chemistry parameters including Albumin and Protein. Baseline was defined as the value obtained prior to first dosing (Day 1). Change from Baseline was calculated by subtracting post-dose value from Baseline value. 99999 indicates data was not available as standard deviation could not be calculated due to insufficient number of participants.

    End point description
    A complete physical examination included, at a minimum, assessment of the Cardiovascular, Respiratory, Gastrointestinal and Neurological systems. A brief physical examination included, at a minimum assessments of the skin, lungs, cardiovascular system, and abdomen (liver and spleen). This analysis was planned but data was not captured in the database. Abnormal changes were captured as adverse events if they were clinically significant.

    Blood samples were collected at indicated time points to evaluate concentration of GSK2879552. Each Pharmacokinetic (PK) sample was collected as close as possible to the planned time relative to the dose (i.e., time zero) administered to the participant on PK days. PK Concentration Population consisted of all participants in the All Treated Subject Population for whom a blood samples for pharmacokinetics were obtained and analyzed. 99999 indicates data was not available as standard deviation could not be calculated due to insufficient number of participants. For Cycle 1, Day 1, pre-dose, all concentration values were less than the lower limit of quantification, therefore they have been imputed with 0 because they were so small. Hence, standard deviation was not calculated as it would result to “0” and would be misleading. Only those participants with data available at the specified data points were analyzed (represented by n= X in the category titles).

    End point description
    Overall survival is defined as the time from first treatment dose until death due to any reason. For the analysis of overall survival, the last date of known contact was to be used for those participants who had not died at the time of analysis; such participants were to be considered censored. Data was not collected for this endpoint as study was terminated during Part 1 and Part 2 was not initiated.

    End point description
    Time to AML progression is defined as the time from first treatment dose until AML progression or crossover if using the All Treated Subjects Population. For the analysis of time to AML, if the participant did not experience AML, time to AML was to be censored at the last treatment prior to the initiation of anti-cancer therapy or crossover.
