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   43977   clinical trials with a EudraCT protocol, of which   7312   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.

    General information about the trial
    Main objective of the trial
    This is a Phase I/II multicenter, first-in-human open-label, dose escalation study to evaluate the safety, tolerability, and anti-tumor activity of intratumoral (IT)/intralesional (IL) injections of MK-4621 (RGT100) in adult participants with selected advanced or recurrent tumors..

    End point description
    An AE was defined as any untoward medical occurrence in a study participant administered study treatment which did not necessarily have a causal relationship with this treatment. Treatment-related was defined as having a “Possible” or “Related” relationship to study treatment, as assessed by the Investigator. Severity of AE referred to the extent to which an AE affected the participants daily activities as assessed by the Investigator and was based on NCI CTCAE grades: Grade 1 (Mild); Grade 2 (Moderate); Grade 3 (Severe or medically significant but not immediately life-threatening); Grade 4 (Life-threatening consequences); or Grade 5 (Death related to AE). The number of participants who experienced at least one treatment-related AE or laboratory abnormality are presented by severity. The safety population consisted of all participants who received ≥1 injection of MK-4621.

    DLTs were assessed during the 1st treatment cycle (28 days) & were defined as any drug-related toxicity that occurred during the 28-day DLT period & included: • Non-hematologic toxicity Grade ≥3 (except diarrhea, nausea, & vomiting unless lasting >3 days despite optimal supportive care); • Confirmed non-hematologic appropriately graded laboratory findings of Grade ≥3 that were ≤ Grade 1 at baseline; • Hematologic toxicity: Grade 4 neutropenia ≥5 days, or Grade 3 neutropenia with fever (fever is >38.4ºC); Grade 4 thrombocytopenia, or Grade 3 thrombocytopenia lasting >7 days or with bleeding; and • Any other toxicity assessed as related to MK-4621, & which, in the opinion of the Investigator & the Sponsor physician constituted a DLT. The number of participants who experienced a DLT is presented by NCI CTCAE version 4.03 severity grade. The DLT evaluable population consisted of participants who completed Cycle 1 (Day 28) or withdrew early for experiencing a DLT.

    		 Objective Response Rate as Evaluated Radiologically Using Immune-related Response Evaluation Criteria in Solid Tumors (irRECIST)
    End point description
    ORR was defined as the percentage of participants who had a Complete Response (CR) or a Partial Response. Per irRECIST, CR (irCR) was defined as the complete disappearance of all measurable and non-measurable lesions. Lymph nodes must also have decreased to <0 mm in short axis. And, per irRECIST, Partial Response (irPR) was defined as a decrease of ≥30% in total measured tumor burden (TMTB) relative to baseline. For this study, irRECIST was modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. The percentage of participants who experienced an irCR or irPR based on irRECIST is presented. The efficacy population consisted of all allocated participants.
