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   43871   clinical trials with a EudraCT protocol, of which   7290   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
    To evaluate the clinical efficacy of 2 doses of GSK2857916 in participants with relapsed/refractory multiple myeloma
    Protection of trial subjects
    In order to minimize corneal events associated with GSK2857916 prophylactic preservative-free artificial tears should be administered in each eye at least 4 to 8 times daily beginning on Cycle 1 Day 1 until the end of treatment. In the event of ocular symptoms (e.g., dry eyes), the use of artificial tears may be increased up to every 2 hours as needed. While not yet clinically demonstrated, it is theoretically possible that the application of a cooling eye mask during GSK2857916 administration, and in the first few hours after infusion may subsequently decrease ocular side effects. On the day of infusion at the discretion of the participant and the investigator, the following may be considered: • Beginning with the start of each GSK2857916 infusion, participants may apply cooling eye masks to their eyes for approximately 1 hour or as much as tolerated. • Participants may continue using the cooling eye mask beyond the first hour for up to 4 hours. Further use beyond 4 hours is at the participant’s discretion. Participants should receive full supportive care during the study, including transfusions of blood products, growth factors, and treatment with antibiotics, anti-emetics, antidiarrheal, and analgesics, as appropriate. Concomitant therapy with bisphosphonates is allowed. Participants may receive local irradiation for pain or stability control.

    End point description
    ORR was determined according to the 2016 international myeloma working group (IMWG) response criteria by IRC. ORR was calculated as the percentage of participants with a confirmed partial response (PR) or better (that is [i.e.], PR, very good partial response [VGPR], complete response [CR] and stringent complete response [sCR]). Confidence intervals were based on the exact method. Full Analysis Population comprised of all randomized participants (any participant who received a treatment randomization number was considered as randomized) whether or not randomized treatment was administered. This population was based on the treatment the participant was randomized to.

    End point description
    CBR was determined according to the 2016 IMWG response criteria by IRC. CBR was calculated as the percentage of participants with a confirmed MR or better (i.e., MR, PR, VGPR, CR and sCR). Confidence intervals were based on the exact method. Data is not presented for 'GSK2857916 3.4 mg/kg (Lyophilized)' arm as it is not included in Efficacy Population.

    End point description
    DoR is defined as the time from first documented evidence of PR or better until the earliest date of documented disease progression (PD) per IMWG response criteria; or death due to PD among participants who achieved an overall response, i.e., confirmed PR or better. DOR based on responses assessed by investigator is presented. Median and inter-quartile range (first quartile and third quartile) of DOR are presented. Only those participants with data available at the specified data points were analyzed. 99999 indicates <50% of participants experienced the event within the treatment arms; 2.5 mg/kg (frozen liquid) and 3.4 mg/kg (lyophilized). Hence, median and third-quartile could not be derived. 88888 indicates <25% of participants experienced the event within the treatment arm; 3.4 mg/kg (frozen liquid).

Full Safety Population(FSP) comprised of all participants who received at least 1dose of frozen liquid or lyophilized powder.3out of 221participants did not receive any study treatment, were excluded from FSP. All the participants in the study were included (95, 99 and 24 Participants), but only those participants with data available at the specified data points were analyzed (represented by n=X in the category titles).

    		 Number of participants with grade change from Baseline in hematology parameters
    End point description
    Blood samples were collected for the analysis of following hematology parameters: hemoglobin (Hb), lymphocyte count (Lymph), neutrophil count (Neutro), platelet count (PC), and leukocyte count (leuko). The laboratory parameters were graded according to National Cancer Institute – Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 4.03. Grade 1: mild; Grade 2: moderate; Grade 3: severe or medically significant; Grade 4: life–threatening consequences. Baseline was defined as latest pre-dose assessment (Day 1) with a non-missing value, including unscheduled visits. An increase is defined as an increase in CTCAE grade relative to Baseline grade. Data for worst-case post Baseline is presented. Only those participants with increase to grade 3 and increase to grade 4 have been presented. 3 participants out of 221 participants did not receive any study treatment and thus, were excluded from the Full Safety Population.

    End point description
    Blood samples were collected for analysis of bicarbonate, direct bilirubin(D.Bil), calcium, chloride, lactate dehydrogenase(LDH), total protein, urea or blood urea nitrogen(BUN),estimated glomerular filtration rate (eGFR).Baseline is latest pre-dose assessment(Day 1) with a non-missing value, including unscheduled visits. If values were unchanged (example: high to high), or whose value became normal, were recorded in the change to normal or NC category. Participants were counted twice if the participant had both decreased to low and increased to high during post Baseline. 3 out of 221participants did not receive any study treatment, were excluded from FSP. All the participants in the study were included in the analysis (95, 99 and 24 Participants), but only those participants with data available at the specified data points were analyzed (represented by n=X in the category titles).

    End point description
    An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. SAE is defined as any untoward medical occurrence that; results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, other situations judged by physician, is associated with liver injury and impaired liver function. Number of participants who had SAEs and common (>=5%) non-SAEs are presented. Number of participants with AESI (keratopathy, dry eye events, blurred vision, thrombocytopenia, infusion-related reactions, corneal events and neutropenia) are also presented. 3 participants out of 221 participants did not receive any study treatment and thus, were excluded from the Full Safety Population.

    End point description
    Baseline was defined as latest pre-dose assessment (Day 1) with a non-missing value, including unscheduled visits. BCVA score was assessed individually for each eye. BCVA test scores were categorized as no change/improved vision, possible worsened vision and definite worsened vision. No change/improved vision was defined as a change from Baseline <0.12 Logarithm of the Minimum Angle of Resolution (logMAR) score; a possible worsened vision was defined as a change from Baseline >=0.12 to <0.3 logMAR score; a definite worsened vision was defined as a change from Baseline >=0.3 logMAR score. 3 participants out of 221 participants did not receive any study treatment and thus, were excluded from the Full Safety Population. All the participants in the study were included in the analysis (95, 99 and 24 Participants), but only those participants with data available at the specified data points were analyzed (represented by n=X in the category titles).

    End point description
    Serum samples were collected for the determination of anti-GSK2857916 antibodies (ADA) using a validated electrochemiluminescent (ECL) immunoassay. The assay involved screening, confirmation and titration steps. If serum samples tested positive in the screening assay, they were considered 'potentially positive' and were further analyzed for the specificity using the confirmation assay. Samples that confirmed positive in the confirmation assay were reported as 'positive'. Confirmed positive ADA samples were further characterized in the titration assay to quasi-quantitate the amount of ADA in the sample. Additionally, confirmed positive ADA samples were also tested in a validated neutralizing antibody assay to determine the potential neutralizing activity of the ADA. 3 participants out of 221 participants did not receive any study treatment and thus, were excluded from the Full Safety Population. Only those participants with data available at the specified data points were analyzed.

    End point description
    The PRO-CTCAE is a patient-reported outcome measure developed to evaluate symptomatic toxicity in participants on cancer clinical trials. It included symptomatic toxicities drawn from the CTCAE like blurred vision (BV), chills, constipation, decreased appetite (DA), fatigue, general pain (GP), heart palpitations (HP), mouth/throat (M/T) sores, nausea, nosebleed, shortness of breath (SB), vomiting and watery eyes (WE). Items were scored individually on a 0 to 4 scale for severity, frequency and interference. Number of participants with symptomatic AEs (those who had a maximum post-Baseline rating greater than 0, example; 1, 2, 3, or 4) measured by PRO-CTCAE are presented. 3 participants out of 221 participants did not receive any study treatment and thus, were excluded from the Full Safety Population.

    		 Worst change from Baseline in National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25) overall composite score
    End point description
    The NEI-VFQ-25 consisted of a base set of 25 vision-targeted questions representing 11 vision-related constructs, plus an additional single-item general health rating question to assess the impact of ocular toxicity on visual function. Items were coded to a 0 to 100 scale and averaged to calculate domains. Domain scores ranged from 0 to 100; higher scores are better. Therefore, increase in score means improvement. Baseline was defined as latest pre-dose assessment (Day 1) with a non-missing value, including unscheduled visits. Change from Baseline was calculated by subtracting Baseline value from the post-dose visit value. Data for worst-case post Baseline is presented. 3 participants out of 221 participants did not receive any study treatment and thus, were excluded from the Full Safety Population. Only those participants with data available at the specified data points were analyzed.

    End point description
    The OSDI is a 12-item questionnaire designed to assess both the frequency of dry eye symptoms and their impact on vision-related functioning. The total OSDI score was calculated as (sum of scores for all questions answered*100) divided by (total number of questions answered*4). Domain scores ranged from 0 to 100; lower scores are better. Therefore, decrease in score from Baseline means improvement. Baseline was defined as latest pre-dose assessment (Day 1) with a non-missing value, including unscheduled visits. Change from Baseline was calculated by subtracting Baseline value from the post-dose visit value.

    The EORTC QLQ-C30 includes physical functioning [PF], role functioning [RF], cognitive functioning [CF], emotional functioning [EF] and social functioning [SF]), (fatigue, pain and nausea/vomiting [N/V]), a global health status (GHS)/ Quality-of-Life (QoL) scale, (constipation, diarrhea, insomnia, dyspnea, appetite loss [AL] and financial difficulties [FD]). Response options: 1 to 4. Scores were averaged and transformed to 0 to 100, a high score for functional scales/ GHS/QoL- better functioning ability or health-related quality-of-life (HRQoL), whereas a high score for symptom scales/ single items- significant symptomatology. Baseline was defined as latest pre-dose assessment with a non-missing value, including unscheduled visits. Change from Baseline was calculated by post-dose visit minus Baseline value. Only those participants with data available at the specified data points were analyzed (represented by n=X in the category titles). 99999 indicates the data is not available.

    		 Change from Baseline in EORTC QLQ 20-item multiple myeloma module (MY20) score
    End point description
    The EORTC QLQ-MY20 is a supplement to the QLQ-C30 instrument used in participants with multiple myeloma. The module comprised of 20 questions that addressed four myeloma-specific HRQoL domains: disease symptoms (DS), side effects of treatment (SET), future perspective (FP) and body image (BI). Responses are 1 to 4. Scores were averaged and scales were transformed to 0 to 100 scale. A high score for disease symptoms and side effects of treatment represented a high level of symptomatology or problems, whereas a high score for future perspective and body image represented better outcomes. Baseline was defined as latest pre-dose assessment (Day 1) with a non-missing value, including unscheduled visits. Change from Baseline was calculated by subtracting Baseline value from the post-dose visit value. Only those participants with data available at the specified data points were analyzed (represented by n=X in the category titles). 99999 indicates the data is not available.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    02 Apr 2018
    Amendment 01: Addressed regulatory agency advice. The original single-arm design with 1 dose level (3.4 milligram per kilogram [mg/kg] GSK2857916 once every 3 weeks [Q3W]) was amended to an open label, randomized, 2-arm study with 2 dose levels by including the 2.5 mg/kg Q3W dose. In addition, a new exploratory cohort of 25 participants, who will receive a lyophilized configuration of GSK2857916, was added to gain clinical experience with the lyophilized configuration. To accommodate these main changes, the overall sample size and related analytical methods were changed.
    30 Aug 2018
    Amendment 02: Addressed feedback from regulatory agencies, ethics commitee/institutional review board, and investigators. The updates included the addition of Exclusion Criteria defining the use of high dose steroids, clarification of specific timeframe from last treatment required for systemic anti-myeloma therapy, and increase of corrected QT interval Fridericia criteria. Additional pharmacokinetic sampling timepoints were added to capture the maximum observed concentration of the free cytotoxic drug (cysteine-maleimidocaproyl monomethyl auristatin F [cys-mcMMAF]) and to better define the kinetics of cys-mcMMAF and the elimination phase of antibody drug conjugate and cys-mcMMAF. Soluble B-cell maturation antigen (BCMA) collection timepoints were also added to capture the effect of GSK2857916 administration on soluble BCMA concentrations over time as a marker of pharmacodynamic effect. The dose modifications guidelines for GSK2857916 related Corneal Events clarified dose adjustments for GlaxoSmithKline Scale Grade 2 events.
    17 Dec 2018
    Amendment 03: Addressed over-enrolment in the frozen liquid solution portion of the study. Due to the over-enrolment, the primary analysis will be based on all randomized participants (anticipated approximately 200) enroled into the frozen liquid solution arms. In addition, a sensitivity analysis based on the first 130 participants will be performed to account for the original design.
    21 Oct 2019
    Amendment 04: Updated schedule of activities to include the footnotes. Updated risk assessment, modified dose justification, modified treatments administered, updated dose reducations for toxicity, modified corneal supportive care guidelines and schedule of activities, updated guidance on prohibited medications, updated requirements for efficacy assessments, modified timeframes for contraception usage in males and females, modified monocular prophylaxis and treatment, updated immunogenicity, updated timeframe of minimal residual disease testing, updated GlaxoSmithKline corneal event severity scale and mitigation strategy for treatment related corneal events.
