Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   41449   clinical trials with a EudraCT protocol, of which   6808   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    - To determine the safety, tolerability and maximum tolerated dose (MTD) of GSK525762 in subjects 16 years or older following QD and/or BID dosing schedules.

    - To evaluate the clinical activity of GSK525762 in NMC and other solid tumors.

    - [US Clinical sites only] To evaluate, after single dose administration, the relative bioavailability of the GSK525762 besylate tablet compared to the amorphous free-base tablet, the effect of high-fat high-calorie meal on the bioavailability of the besylate tablet and the dose proportionality of two doses of GSK525762 administered as the besylate tablets.
    E.2.2Secondary objectives of the trial
    - To characterize the pharmacokinetics (PK) of GSK525762 in subjects 16 years or older following QD and/or BID dosing schedules.

    - To evaluate cardiac safety, including the potential for QTcF changes with GSK525762 and to assess PK/QTcF relationship following QD and/or BID dosing schedules.

    - To evaluate the exposure response (pharmacokinetic/pharmacodynamic [PK/PD]) relationship between GSK525762 and safety and efficacy parameters following QD and/or BID dosing schedules.

    - To evaluate the effect of treatment with GSK525762 on tumor growth and survival.
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Title: Besylate Sub-Study [US Clinical sites only]

    Objective: To determine the relative bioavailability (BA), food effect, and dose proportionality of the besylate formulation of GSK525762 at or near the MTD

    Title: Pharmacogenetic Research

    Objectives: The objective of the PGx research (if there is a potential unexpected or unexplained variation) is to investigate a possible genetic relationship to handling or response to GSK525762. If at any time it appears there is potential variability in response in this clinical study or in a series of clinical studies with GSK525762 that may be attributable to genetic variations of subjects, the following objectives may be investigated – the relationship between genetic variants and study treatment with respect to:

    - Pharmacokinetics and/or pharmacodynamics of study treatment,

    - Safety and/or tolerability, and

    - Efficacy.
    E.3Principal inclusion criteria
    1. Male or female 16 years or older, at the time of signing the informed consent.

    2. Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form. If the subject is less than 18 years old, an Assent form and parental/guardian Consent form (replacing “you will” with “your child will” will be required).

    3. Diagnosis of one of the following:

    Part 1 Only:

    - NUT Midline Carcinoma based on ectopic expression of NUT protein as determined by IHC and/or detection of NUT gene translocation as determined by FISH. Subjects may be treatment naïve or have had prior therapy.

    - SCLC, CRC, NB, TNBC, ER positive BC, CRPC, NSCLC, and any other solid tumor which has been confirmed by clinical testing to be MYCN amplified (defined as a MYCN gene copy number gain of ≥5). Subjects should have tumor progression after receiving at least one prior standard/approved chemotherapy, or where there is no approved therapy, or where standard therapy is refused.

    Part 2 Only:

    - NUT Midline Carcinoma as diagnosed by the Central Laboratory. Subjects may be treatment naïve or have had prior therapy.

    - SCLC, CRPC, TNBC and ER+BC

    4. Subjects with solid tumors, with the exception of CRPC, must demonstrate measurable disease, per RECIST v1.1. NOTE: Subjects with NMC that do not meet the RECIST v1.1 criteria for measurable disease, but have evaluable disease may be considered for enrollment after discussion with the GSK medical monitor.

    5. All prior treatment- related toxicities must be CTCAE (Version 4.0) ≤ Grade 1 (except alopecia and peripheral neuropathy) at the time of treatment allocation.

    6. ECOG Performance Status score of 0 to 2 for subjects with NMC; 0-1 for subjects with other tumor types.

    7. Adequate organ function as defined in Table 8.

    See table in the protocol

    8. Able to swallow and retain orally administered medication and does not have any clinically significant gastrointestinal abnormalities that may alter absorption such as malabsorption syndrome or major resection of the stomach or bowels.

    9. A female subject is eligible to participate if she is of:

    - Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) >40 MlU/ml and estradiol <40 pg/ml (<140 pmol/L) is confirmatory]. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use study. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal status prior to study enrollment. For most forms of HRT, at least 2 to 4 weeks will elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. Following confirmation of their post-menopausal status, they can resume use of HRT during the study without use of a contraceptive method.

    - Child-bearing potential and agrees to use one of the contraception methods (described in Section 9.1) for an appropriate period of time (as determined by the product label or investigator) prior to the start of dosing to sufficiently minimize the risk of pregnancy at that point. Female subjects must agree to use contraception until 7 months after the last dose of study medication.

    - Negative serum pregnancy test ≤ 7 days prior to first study drug dose.

    - Female subjects who are lactating must discontinue nursing prior to the first dose of study treatment and must refrain from nursing throughout the treatment period and for 5 half-lives of GSK525762 or at least 28 days (whichever is longer) following the last dose of study treatment.

    10. Male subjects must agree to use one of the methods of contraception specified.

    E.5 End points
    E.5.1Primary end point(s)
    • AEs, SAEs, dose reductions or delays, withdrawals due to toxicities and changes in safety assessments (e.g., laboratory parameters, vital signs, ECG, cardiotoxicity, gastrointestinal, etc) to determine the MTD in subjects 16 years or older

    • Assess overall response rate (RR) by RECIST 1.1 in NMC and other solid tumors.

    • PK parameter values for GSK525762 following single oral administration as amorphous free-base or besylate tablet
    E.5.1.1Timepoint(s) of evaluation of this end point
    Part 1: Dose limiting toxicity will be evaluated during the first 4 weeks of treatment but all other safety parameters and adverse events are followed until the patient discontinues the study.

    Part 2: The response rate will be assessed until a subject has disease progression or terminates the study.
    E.5.2Secondary end point(s)
    • PK parameter values for GSK525762 following single and repeat-dose oral administration in subjects 16 years or older

    • Changes in cardiac safety including QTcF following single and repeat-dose oral administration GSK525762.

    • Progression free survival (PFS), time to response, duration of response, overall survival (OS), and exploratory analysis for antitumor response by various imaging modalities.
    E.5.2.1Timepoint(s) of evaluation of this end point
    Part 1: Subjects will be evaluated for secondary endpoints such as pharmacokinetics for the first 4 weeks, at Week 9, and every 8 weeks for subjects on study longer than 13 weeks.

    Part 2: Subjects will be evaluated for secondary endpoints for the first 4 weeks and subsequently at Week 5, Week 9, and Week 10. Subjects will then be evaluated 3 weeks after Week 13, and every 4 weeks thereafter.

    In both Part 1 and Part 2, subjects will receive study treatment until disease progression, death or unacceptable adverse event. A subject will be considered to have completed the study 2 years after the last treatment or if the subject dies or is still in follow-up at the time the study is closed or terminated, whichever is sooner.
