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   44236   clinical trials with a EudraCT protocol, of which   7337   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.

    4. For expansion phase only: SCCHN (Part 2): • Participants with histologically confirmed (cytological diagnosis is acceptable) metastatic or recurrent, unresectable SCCHN that is considered incurable by local therapies. Participants should not have had prior systemic therapy administered in the recurrent or metastatic setting. Systemic therapy which was completed more than 6 months before signing consent if given as part of multimodal treatment of locally advanced disease is allowed. •Anatomic subsites to be included are oral cavity, oropharynx, hypopharynx, larynx, nasal cavity, and paranasal sinuses (maxillary, ethmoid, sphenoid, and frontal). The exception to this is nasopharyngeal cancer and salivary gland tumors, which will not be included. •Participants with oropharyngeal cancer or tumors arising in the paranasal sinuses (maxillary, ethmoid, sphenoid, and frontal) must agree to provide archival tissue for human papilloma virus (HPV) testing - For Part 2A, tumors must have a PD-L1 combined positive score (CPS)
    ≥1. For Part 2B, any CPS is eligible. •For Part 2B, participants must be eligible to receive treatment with either cisplatin or carboplatin in combination with 5-fluorouracil (5FU) per the treating physician.
    5. CRC (Part 3):
    •Third-line or later MSI-H/dMMR CRC (Part 3A): Participants with histologically confirmed (cytological diagnosis is acceptable) recurrent locally advanced or metastatic MSI-H/dMMR CRC whose disease has progressed on or following therapy with 1) an antiPD-(L)1 or PD-L1 antibody (ie, pembrolizumab) and 2) at least one line of combination chemotherapy including a fluoropyrimidine and irinotecan OR oxaliplatin with or without an anti- epidermal growth factor receptor (EGFR) or anti-vascular endothelial growth factor (VEGFR) monoclonal antibody (ie, cetuximab or bevacizumab). MSI-H/dMMR CRC participants must have received at least 6 weeks of prior treatment with an anti-PD-1 or PD-L1 antibody.
    •Third-line MSS/pMMR CRC (Part 3B): Participants with histologically confirmed (cytological diagnosis is acceptable) recurrent locally advanced or metastatic MSS/pMMR CRC whose disease has progressed on or following therapy with 2 different lines of combination chemotherapy, including therapy with a fluoropyrimidine and irinotecan AND therapy with a fluoropyrimidine and oxaliplatin. Both lines of therapy may be given with or without an anti-EGFR or anti-VEGFR monoclonal antibody (ie, cetuximab or bevacizumab). Participants with MSS/pMMR CRC must have progressed on or after combination chemotherapy regimens containing BOTH irinotecan AND oxaliplatin.
    •Participants with MSI-H/dMMR or MSS/pMMR CRC must have MSI/MMR status assessed by certified/accredited lab immunohistochemistry (IHC) and/or polymerase chain reaction (PCR) assay.
    •Participants with MSI-H/dMMR or MSS/pMMR CRC must have been treated with 2 prior lines of therapy in the recurrent locally advanced or metastatic setting.
    6.Adequate bone marrow, renal, hepatic and cardiac functions.
    7.Left ventricular ejection fraction (LVEF) >50%, as measured by echocardiogram or multiple-gated acquisition (MUGA) scan within 4 weeks before receiving the first dose of study drug.
    8.Clinically significant toxic effects of previous therapy have recovered to Grade 1 (per NCI CTCAE Version 5.0) or baseline
    9.Dose escalation Part 1, once peripheral evidence of TAK-676 pharmacodynamic stimulation of the innate and/or adaptive immune system is observed in the blood and/or clinical response/partial response (CR/PR) is observed in at least 1 participant, subsequent participants must:
    •Have at least 1 lesion amenable for biopsy
    •Agree to have 2 tumor biopsies: 1 during the screening period and 1 while on TAK-676 treatment.

    2. Response assessments per Response Evaluation Criteria in Solid Tumors (RECIST) v.1.1 (Eisenhauer et al. 2009) by investigator.
    – ORR (confirmed complete response [cCR] + confirmed partial response [cPR]).
    – Disease control rate (DCR) (cCR + cPR + stable disease [SD] >6 weeks).
    – Duration of response (DOR).
    – Time to response (TTR).
    3. Upregulation of TAK-676–induced STING agonism gene expression signature in peripheral blood.
    4. Evaluation of T-cell infiltration upon TAK-676 treatment (parts 1A, 1B, 2 and 3).
    5. Genomic, transcriptomic and protein expression analyses of baseline and on-treatment tumor tissue (parts 1A, 1B, 2 and 3).

    Expansion phase only:
    1. Response assessments per RECIST v.1.1 by investigator
    – Progression-free survival (PFS)
    – OS
    – OS rate at 12 months
    – OS rate at 6 months
    E.5.2.1Timepoint(s) of evaluation of this end point
    Dose Escalation and Expansion Phases: Cycle 1 Days 1, 8 and 15: pre-infusion and at multiplepoints (up to 24 hours) post-infusion and at Day 1 for further cycles up to 54 months (Cycle length=21 days)]
