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   43874   clinical trials with a EudraCT protocol, of which   7294   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.

    E.4Principal exclusion criteria
    1. Received temozolomide or DTIC at any time
    2. Any other systemic anticancer therapy including investigational agents ≤3 weeks before initiation of study treatment. Additionally, subjects may not have received radiation ≤3 weeks before initiation of study treatment.
    3. Known intolerance to DTIC or one or more of the excipients in unesbulin.
    4. Co-existing active infection or any co-existing medical condition likely to interfere with study procedures, including:
    a. Significant cardiovascular disease (New York Heart Association Class III or IV cardiac disease), myocardial infarction within the past 6 months, unstable angina, congestive heart failure requiring therapy, unstable arrhythmia or a need for anti-arrhythmic therapy, or evidence of ischemia on ECG, marked baseline prolongation of QT/QTc (corrected QT) interval, eg, repeated demonstration of a QTc interval >500 msec (Long QT Syndrome [congenital])
    5. Known human immunodeficiency virus, hepatitis B virus, or hepatitis C virus positivity
    6. History of solid organ transplantation
    Therapeutics:
    7. Known or suspected allergy or immediate or delayed hypersensitivity to unesbulin or dacarbazine, their excipients, or any agent given in this study
    Gastrointestinal:
    8. Bowel obstruction, malabsorption, or other contraindication to oral medication
    9. Gastrointestinal disease or other conditions that could affect absorption. Active peptic ulcer disease or previous history of gastric perforation within the last 2 years
    10. Inflammatory bowel disease (including ulcerative colitis and Crohn’s disease), diverticulitis, cholecystitis, symptomatic cholangitis, or appendicitis
    Wounds/surgery:
    11. Serious non-healing wound, ulcer, or bone fractures
    12. Major surgery, open biopsy, or significant traumatic injury that has not recovered, in the opinion of the investigator, within 28 days of baseline

CYP1A2 inhibitors may inhibit the conversion of DTIC to its active metabolite and may increase the exposure of unesbulin.
    15. Concomitant use of moderate CYP1A2 inducers (such as phenytoin, rifampin, ritonavir, teriflunomide, and barbiturates) and chronic use of marijuana. CYP1A2 inducers may increase the conversion of DTIC to its active metabolites.

Cancer treated with curative intent more than 5 years previously and without evidence of recurrence is not an exclusion.
    19. Known coagulopathy or bleeding diathesis. Subjects on anti-coagulation should be monitored closely and International Normalized Ratio within normal range.
    20. Prior or ongoing clinically significant illness, medical or psychiatric condition, medical history, physical findings, ECG findings, or laboratory abnormality that, in the investigator’s opinion, could affect the safety of the subject, or alter the absorption, distribution, metabolism, or excretion of the study drugs, or could impair the assessment of study results.
    21. History of brain metastases or leptomeningeal disease at any time in subject’s history, including treated central nervous system (CNS) disease
    1. Tratamiento con temozolomida o DTIC en cualquier momento.

    estudio.
    3. Intolerancia conocida a la DTIC o a uno o más de los excipientes de la unesbulina.
    4. Infección activa coexistente o cualquier trastorno médico coexistente que probablemente interfiera en los procedimientos del estudio, como:
    a. Enfermedad cardiovascular importante (cardiopatía de clase III o IV de la New York Heart Association), infarto de miocardio en los 6 últimos meses, angina inestable, insuficiencia cardíaca congestiva con necesidadde tratamiento, arritmia inestable o necesidad de tratamiento antiarrítmico o signos de isquemia en el ECG, prolongación basal notable del intervalo QT/QTc (QT corregido), por ejemplo, demostración repetida de un intervalo QTc >500 ms (síndrome de QT largo [congénito]).
    5. Positividad conocida para el virus de la inmunodeficiencia humana, el virus de la hepatitis B o el virus de la hepatitis C.
    6. Antecedentes de trasplante de órgano sólido.
    Terapéuticos:
    7. Confirmación o sospecha de alergia o de hipersensibilidad inmediata o tardía a la unesbulina o la dacarbazina, sus excipientes o cualquier fármaco administrado en este estudio.
    Gastrointestinales:
    8. Obstrucción intestinal, malabsorción u otra contraindicación de la medicación oral.
    9. Enfermedades digestivas u otros trastornos que puedan afectar a la absorción. Úlcera péptica activa o antecedentes de perforación gástrica en los 2 últimos años.
    10. Enfermedad inflamatoria intestinal (como colitis ulcerosa y enfermedad de Crohn), diverticulitis, colecistitis, colangitis sintomática o apendicitis.
    Heridas/cirugía:
    11. Herida o úlcera no cicatrizada o fractura ósea no consolidada importantes.
    12. Cirugía mayor, biopsia abierta o traumatismo importante que, en opinión del investigador, no se haya recuperado en los 28 días previos a la visita basal.
    13. Hemorragia mucosa o interna.
    Medicamentos concomitantes:
    14. Se debe evitar el uso concomitante de inhibidores potentes de la CYP1A2 (como las fluoroquinolonas [antibióticos quinolónicos de amplio espectro, incluidos enoxacino y ciprofloxacino] y los inhibidores selectivos de la recaptación de serotonina [ISRS] fluvoxamina y
    fluoxetina) el mismo día que se administre DTIC o unesbulina. Los inhibidores de la CYP1A2 pueden inhibir la conversión de DTIC en su
    metabolito activo y aumentar la exposición a la unesbulina.
    15. Uso concomitante de inductores moderados de la CYP1A2 (como fenitoína, rifampicina, ritonavir, teriflunomida y barbitúricos) y uso crónico de marihuana. Los inductores de la CYP1A2 pueden aumentar la conversión de DTIC en sus metabolitos activos.
    16. Debe evitarse la administración conjunta de fármacos reductores del ácido aproximadamente 4 horas antes y después de la administración de unesbulina.
    17. Uso concomitante activo de antiinflamatorios no esteroideos orales durante más de 2 años por enfermedades crónicas.
    Otros:
    18. Neoplasias malignas previas, distintas del LMS, que hayan precisado tratamiento o hayan mostrado signos de recidiva (excepto cáncer de piel distinto del melanoma, carcinoma in situ de cuello uterino debidamente tratado, cáncer de próstata in situ o cualquier otra neoplasia maligna de bajo riesgo aprobada por el monitor médico) durante los 5 años previos al inicio. El cáncer tratado con intención curativa más de 5 años antes y sin signos de recidiva no es motivo de exclusión.
    19. Coagulopatía o diátesis hemorrágica conocidas. Se vigilará estrechamente a los sujetos que estén recibiendo anticoagulantes y se
    mantendrá el índice internacional normalizado dentro del intervalo normal.
    20. Enfermedad, trastorno médico o quirúrgico, hallazgo físico, antecedente médico, hallazgo físico, resultado del ECG o anomalía analítica de importancia clínica, ya sea previo o actual, que en opinión del investigador, pueda afectar a la seguridad del sujeto, modificar la absorción, distribución, metabolismo o excreción de los fármacos del estudio o afectar a la evaluación de los resultados del estudio.
    21. Antecedentes de metástasis cerebrales o enfermedad leptomeníngea en cualquier momento de la vida del sujeto, incluida una enfermedad del sistema nervioso central (SNC) tratada.
