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   43857   clinical trials with a EudraCT protocol, of which   7284   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.2 Objective of the trial
    E.2.1Main objective of the trial
    To determine the antitumor activity of single-agent enfortumab vedotin as measured by confirmed ORR in patients with locally advanced or metastatic urothelial cancer who have previously received systemic therapy with a CPI and either previously received platinum-containing chemotherapy or are platinum-naïve and cisplatin-ineligible
    E.2.2Secondary objectives of the trial
    ● To assess DOR
    ● To assess disease control rate (DCR)
    ● To assess PFS
    ● To assess OS
    ● To assess the safety and tolerability of enfortumab vedotin
    ● To assess the pharmacokinetics (PK) of enfortumab vedotin
    ● To assess the incidence of antitherapeutic antibodies (ATA)
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    • Histologically documented urothelial (previously known as transitional cell) carcinoma (squamous differentiation or mixed cell types allowed).
    • Metastatic disease or locally advanced disease that is not resectable.
    • Must have received prior treatment with a CPI in the locally advanced or metastatic urothelial cancer setting. Patients who received CPI therapy in the neoadjuvant/adjuvant setting and had recurrent or progressive disease either during therapy or within 3 months of therapy completion are eligible. A CPI is defined as a programmed cell death protein 1 (PD-1) or programmed death-ligand 1 (PD-L1) inhibitor.
    • Must be one of the following:
    a. Platinum-treated (Cohort 1): Patients who received prior treatment with platinumcontaining chemotherapy defined as those who received platinum in the adjuvant/neoadjuvant setting and had recurrent or progressive disease within
    12 months of completion OR received treatment with platinum in the locally advanced (defined as unresectable with curative intent) or metastatic setting;
    OR
    b.Platinum-naïve and cisplatin ineligible (Cohort 2): Patients who have not received prior treatment with platinum-containing or other chemotherapy in the locally advanced or metastatic setting and are ineligible for treatment with cisplatin at time of enrollment due to one of the following: ECOG performance status score of 2; impaired renal function (defined as creatinine clearance [CrCl] ≥30 and <60 mL/min), or a ≥ Grade 2 hearing loss. Patients who received platinum in the adjuvant/neoadjuvant setting and did not progress within12 months of completion will be considered platinum-naïve.
    • Must have had progression or recurrence of urothelial cancer during or following receipt of most recent therapy.
    • Tumor tissue samples must be available for submission to the sponsor prior to study treatment.
    • Must have measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) (Version 1.1).
    • An Eastern Cooperative Oncology Group (ECOG) Performance Status score of ≤1 for Cohort 1, or ≤2 for Cohort 2.
    E.4Principal exclusion criteria
    • Ongoing sensory or motor neuropathy Grade ≥2.
    • Active central nervous system (CNS) metastases.
    • Ongoing clinically significant toxicity (Grade 2 or higher) associated with prior treatment (including systemic therapy, radiotherapy or surgery). Patients with ≤ Grade 2 hypothyroidism or panhypopituitarism related to treatment with PD-1 and PD-L1 inhibitors may be enrolled. Patients on hormone replacement therapy may be enrolled if on a stable dose. Patients with ≥ Grade 3 immunotherapy-related hypothyroidism or panhypopituitarism are excluded. Patients with immunotherapy related myocarditis, colitis, uveitis, or pneumonitis are excluded. Patients with other immunotherapy related adverse events requiring high doses of steroids (>20 mg/day of prednisone or equivalent) are excluded.
    • Prior enrollment in an enfortumab vedotin study or prior treatment with monomethyl auristatin E (MMAE) based antibody-drug conjugates (ADCs).
    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint of this study is the confirmed Objective Response Rate (ORR) per IRF. The ORR is defined as the
    proportion of patients with confirmed CR or PR according to RECIST Version 1.1 . Patients who do not have at least 2 (initial response and confirmation scan) post-baseline response assessments as described in Section 7.2 of the
    protocol will be counted as non-responders.
    E.5.1.1Timepoint(s) of evaluation of this end point
    According to protocol.
    E.5.2Secondary end point(s)
    The key secondary endpoints are:
    - Duration of Response (DOR);
    - Disease Control Rate at Week 16 (DCR16);
    - Progression-free Survival (PFS);
    - Overall Survival (OS);
    -ORR per investigator.
    E.5.2.1Timepoint(s) of evaluation of this end point
    According to protocol.
