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 ).

    E.3Principal inclusion criteria
    1. Age ≥18 years
    2. Histologically documented, locally advanced (T4b, any N; or any T, N 2-3) or metastatic urothelial carcinoma (M1, Stage IV) (also termed TCC or UCC of the urinary tract; including renal pelvis, ureters, urinary bladder, and urethra). a. Patients with mixed histologies are required to have a dominant transitional cell pattern (small cell carcinoma of any proportion is not allowed). b. Locally advanced bladder cancer must be inoperable on the basis of involvement of pelvic sidewall or adjacent viscera (clinical Stage T4b) or bulky nodal metastasis (N2-N3)
    3. Measurable disease as defined by RECIST v1.1. a. Previously irradiated lesions should not be counted as target lesions unless there has been demonstrated progression in the lesion since radiotherapy and no other lesions are available for selection as target lesions.
    4. Considered to be eligible to receive platinum-based chemotherapy and avelumab maintenance therapy, in the Investigator’s judgment
    5. No prior systemic therapy in the inoperable, locally advanced, or metastatic setting including chemotherapy, immune checkpoint inhibitor therapy, targeted therapy, or investigational agents. a. For patients who received prior adjuvant/neoadjuvant chemotherapy or chemoradiation
    for urothelial carcinoma, a treatment-free interval > 12 months between the last treatment administration and the date of recurrence is required in order to be considered treatment-naïve in the metastatic setting. b. Prior local intravesical chemotherapy or immunotherapy is allowed if completed
    ≥4 weeks prior to the initiation of study treatment.
    6. Provision of a recent formalin-fixed, paraffin-embedded (FFPE) tumor tissue block (75-micron) or at least 15 (5-micron) unstained slides from the most recent primary or metastatic tumor biopsy or resection obtained prior to treatment with first-line chemotherapy but within one year of randomization, with no intervening systemic anti-cancer therapy. If a suitable tissue sample is not otherwise available, then an FFPE tissue block from a de novo biopsy (core needle or excisional) must have been obtained for research purposes prior to randomization in this study. Patients who have fewer than 15 unstained slides available at baseline (but no fewer than 10) may be eligible following discussion with the Medical Monitor. a. Tumor tissue should be of good quality based on total and viable tumor content. For core-needle biopsy specimens, at least three cores should be submitted for evaluation. b. Transurethral resection of bladder tumor (TURBT) specimens must contain a muscle-invasive component (i.e., T2 or greater) of the bladder tumor as verified by local pathology review. If the TURBT specimens do not contain a muscle-invasive component, then specimens obtained at the time of cystectomy/nephroureterectomy (i.e., pT2 or greater) or metastatic spread (i.e., a sample from a metastatic lesion) will be required prior to randomization. An archival specimen, if available, should also be submitted. c. Patients who do not have tissue specimens that meet eligibility requirements may undergo a biopsy during the screening period. Acceptable samples include core needle biopsies for deep tumor tissue (minimum three cores) or excisional, incisional, punch, or forceps biopsies for cutaneous, subcutaneous, or mucosal lesions. d. Tumor tissue from bone metastases is not evaluable for PD-L1 expression and is therefore not acceptable.
    7. ECOG performance status of 0-2
    8. Adequate organ function as demonstrated by the following laboratory values: a. Hemoglobin ≥9.0 g/dL in the absence of RBC transfusion or ESA administration within 14 days prior to first dose of study drug. b. Absolute neutrophil count (ANC) ≥1.5 × 109/L. c. Platelet count ≥100 × 109/L. d. Estimated glomerular filtration rate ≥ 30 mL/minute/1.73 m2. e. Total bilirubin ≤1.5 × upper limit of normal (ULN) (<3 ULN if Gilbert’s disease). f. ALT and AST ≤2.5 × ULN in the absence of liver metastasis or <5 × ULN in the presence of liver metastasis
    9. Resolution of nonhematologic toxicities from prior systemic therapy, radiation therapy, or surgical procedures to ≤ Grade 1. a. Alopecia and sensory neuropathy ≤ Grade 2 not constituting a safety risk based on investigator’s judgment are acceptable
    10. Predicted life expectancy of ≥3 months
    11. Contraceptive use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. Please see Section 17.3 for detailed instructions on methods of contraception requirements.
    12. Capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol
    1. Edad >/=18 años. 2. Carcinoma urotelial localmente avanzado (T4b, cualquier N; o cualquier T, N 2-3) o metastásico (M1, estadio IV) documentado histológicamente (otros nombres con los que también se conoce este tumor son carcinoma de células transicionales o carcinoma de células uroteliales de las vías urinarias; incluidos pelvis renal, uréteres, vejiga y uretra). a. Los pacientes con tumores de histología mixta deben presentar un patrón dominante de células transicionales (no se permite la presencia de carcinoma microcítico). b. El cáncer de vejiga localmente avanzado debe ser inoperable debido a la afectación de la pared lateral pélvica o de vísceras adyacentes (estadio clínico T4b) o a metástasis ganglionares voluminosas (N2-N3). 3. Enfermedad medible según la definición de RECIST v1.1. a. Las lesiones irradiadas previamente no deben contarse como lesiones diana, salvo que se haya demostrado progresión en la lesión después de la radioterapia y no se puedan seleccionar otras lesiones como lesiones diana. 4. Indicación de quimioterapia con derivados del platino y de tratamiento de mantenimiento con avelumab, a juicio del Investigador. 5. No haber recibido tratamiento sistémico con anterioridad para el tumor localmente avanzado o metastásico, inoperable, lo que comprende quimioterapia, tratamiento con inhibidores de los puntos de control inmunitario, tratamiento dirigido o productos en investigación. a. En el caso de los pacientes que hayan recibido previamente quimioterapia o quimiorradioterapia adyuvante/neoadyuvante para el carcinoma urotelial, se requiere un intervalo sin tratamiento >12 meses entre la última administración del tratamiento y la fecha de reaparición del tumor para que se considere que no han recibido tratamiento previo en el contexto metastásico. b. Se permite la quimioterapia o inmunoterapia intravesical local previa si hubiera concluido >/=4 semanas antes del inicio del tratamiento del estudio.
    6. Aportación de un bloque reciente de tejido tumoral fijado con formol e incluido en parafina (75 µm) o un mínimo de 15 preparaciones sin teñir (5 µm) de la biopsia o resección de tumor primario o metastásico más reciente, obtenida antes del tratamiento con quimioterapia de primera línea, pero en el plazo del año anterior a la aleatorización, sin ningún tratamiento sistémico antineoplásico intermedio. Si no se dispone de una muestra de tejido adecuada, deberá haberse obtenido un bloque de tejido fijado con formol e incluido en parafina de una biopsia de novo (con aguja gruesa o por escisión) con fines de investigación antes de la aleatorización en este estudio. Los pacientes con menos de 15 (pero no menos de 10) preparaciones sin teñir en el momento basal podrían entrar en el estudio tras consultarse el caso con el Monitor Médico. a. El tejido tumoral debe ser de buena calidad según el contenido total y viable del tumor. En cuanto a las muestras de biopsia con aguja gruesa, deben enviarse como mínimo tres cilindros para su evaluación. b. Las muestras de tumor vesical obtenidas por resección transuretral deben contener un componente de invasión muscular (es decir, T2 o mayor) del tumor vesical verificado mediante examen en el laboratorio anatomopatológico local. Si dichas muestras obtenidas por resección transuretral no contienen un componente de invasión muscular, se precisarán muestras obtenidas en el momento de la cistectomía o nefroureterectomía (es decir, pT2 o mayor) o de la diseminación metastásica (es decir, una muestra de una lesión metastásica) antes de la aleatorización. Si es posible, también se enviará una muestra de archivo. c. En el caso de los pacientes de los que no se disponga de muestras de tejido que cumplan los requisitos de elegibilidad, podrá practicarse una biopsia durante el periodo de selección. Se consideran muestras aceptables las obtenidas mediante biopsia con aguja gruesa de tejido tumoral profundo (un mínimo de tres cilindros) o por escisión, por incisión, en sacabocados o con pinzas de lesiones cutáneas, subcutáneas o mucosas. d. La expresión de PD-L1 no es evaluable en el tejido tumoral de metástasis óseas, por lo que este no es aceptable. 7. Estado funcional del ECOG de 0-2. 8. Capacidad funcional orgánica adecuada, demostrada por los siguientes valores de laboratorio: a. Hemoglobina >/=9,0 g/dl en ausencia de transfusión de hematíes o administración de estimulantes de la eritropoyesis en los 14 días previos a la primera dosis del fármaco del estudio. b.

    Patients will transition to receive SoC treatment by their healthcare provider outside of this study. In addition, safety Follow-up visits will occur 30 days after their last dose of study drug and 90 days after the last dose of avelumab. Patients will be followed for survival approximately every 3 months after the End of Treatment Visit. Patients will be followed for survival, at a
    minimum, until at least 60% of patients in the study have died, or the end of study, whichever occurs first.
    Los pacientes pasarán a recibir el SoC fuera de este estudio. Las visitas de seguimiento de seguridad se realizarán 30 días después de la última dosis del fármaco del estudio y 90 días después de la última dosis de avelumab. Se hará seguimiento de la supervivencia de los pacientes aprox. cada 3 meses tras la visita de fin de tto. Los pacientes serán como mín. seguidos para la supervivencia hasta que al menos el 60% hayan fallecido, o hasta el final del estudio.
