Brief Summary:
An open-labelled, uncontrolled, single-center Phase I/IIa clinical study to evaluate the safety of repeated infusions of AdVince into the hepatic artery in patients with metastatic neuroendocrine tumors (NETs), and if possible determination of maximum tolerated dose.

Condition or disease Intervention/treatment Phase
Neuroendocrine Tumors Drug: AdVince Phase 1 Phase 2

Detailed Description:
An open-labelled, uncontrolled, single-center Phase I/IIa clinical study to evaluate the safety of repeated infusions of AdVince into the hepatic artery in patients with metastatic neuroendocrine tumors (NETs), and if possible determination of maximum tolerated dose. Secondary objectives include to evaluate the anti-tumoral efficacy of AdVince infusions on metastatic neuroendocrine tumors, to determine the replication profile of AdVince and to determine the humoral (antibody) and cytokine-mediated immune response to AdVince. Minimum 12 and maximum 35 patients will be included, the number is based on the toxicity observed.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of Adverse Events (AE) according to Common Terminology Criteria for Adverse Events (CTCAE) v 4.03 [ Time Frame: From screening visit and through study completion, an average time of 18 months. ]
    AEs probably or possibly related to the study drug or local injuries caused by the administration procedure. If possible identify dose limiting toxicity (DLT), i.e. grade 4 toxicity of any duration or grade 3 toxicity lasting more than 7 days, excluding flu-like symptoms, according to CTCAE v4.03.Clinically significant changes in laboratory parameters (haematology, blood coagulation, liver function, biochemistry and kidney function) and vital signs (body temperature, heart rate, blood pressure, respiratory rate and consciousness according to Reaction Level Scale from 1985 (RLS-85).


Secondary Outcome Measures :
  1. Change in tumor size [ Time Frame: Measured within 4 weeks before first treatment and after 80 +/-14 days (evaluation visit 1) ]
    Computer tomography (CT) and/or positron emission tomography (PET) with magnetic resonance imaging (MRI). Assessment based on Response Evaluation Criteria In Solid Tumors (RECIST) or modified RECIST (mRECIST).

    Computer tomography (CT) and/or positron emission tomography (PET) with magnetic resonance imaging (MRI). Assessment based on Response Evaluation Criteria In Solid Tumors (RECIST) or modified RECIST (mRECIST).

  3. Change in tumor metabolic activity [ Time Frame: Baseline value within 24 hrs before first treatment and after 80 +/- 14 days(evaluation visit 1) ]
    Change in hormone levels including chromogranin- A (CgA), chromogranin-B (CgB), neuron specific enolase (NSE) and specific hormones.

  4. Change in tumor metabolic activity [ Time Frame: Baseline value within 24 hrs before first treatment and after 214 +/- 14 days (evaluation visit 2) ]
    Change in hormone levels including chromogranin- A (CgA), chromogranin-B (CgB), neuron specific enolase (NSE) and specific hormones.

  5. Progression-free survival (PFS) [ Time Frame: Twelve weeks after 80 days from first treatment (4 treatment cycles) or the corresponding time. ]
    Number of patients with progression-free survival (PFS).

  6. Change in replication profile of AdVince [ Time Frame: Before and 4hrs after each treatment cycle up to a time period of 214 days. ]
    Replication profile determined by quantification of adenovirus genomic copies in patient´s blood by quantitative real-time polymerase chain reaction (QRT-PCR).

  7. Change in replication profile of AdVince [ Time Frame: Before and 24hrs after each treatment up to a time period of 214 days. ]
    Replication profile determined by quantification of adenovirus genomic copies in patient´s blood by quantitative real-time polymerase chain reaction (QRT-PCR).

  8. Change in replication profile of AdVince [ Time Frame: Before and 72hrs after each treatment cycle up to a time period of 214 days. ]
    Replication profile determined by quantification of adenovirus genomic copies in patient´s blood by quantitative real-time polymerase chain reaction (QRT-PCR).

  9. Change in the humoral immune response to AdVince [ Time Frame: At baseline, after 8+2 days, after 50 +/- 7days, optional after 124 +/- 7days and 184 +/- 7 days. ]
    Detection of anti-adenovirus neutralizing antibodies against adenovirus.

  10. Change in the cytokine-mediated immune response [ Time Frame: At baseline and at 4hrs following each treatment up to a time period of 214 days. ]
    Measure from patient´s plasma.

  11. Change in the cytokine-mediated immune response [ Time Frame: At baseline and at 24hrs following each treatment up to a time period of 214 days. ]
