E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Neuroendocrine neoplasms (NENs) is a heterogeneous group with varying symptoms, tumor biology and treatment response. NENs may occur in any organ, most commonly they are observed in the gastroenteropancreatic system and lungs. Most NEN patients are diagnosed at advanced stage, 65% of them will die within 5 years. The only curative treatment is surgery with complete resection of the primary tumor. However, more than 50% of patients exhibit metastatic disease, where there is no cure. |
|
E.1.1.1 | Medical condition in easily understood language |
Neuroendocrine neoplasms (NENS) are often observed in the gatroenteropancreatic tissue. The only curative treatment is surgery. However, > 50% of patients exhibit metastases, where there is no cure. |

E.5 End points |
E.5.1 | Primary end point(s) |
(a) Number of Adverse Events (AE) according to CTCA v 4.03, probably or possibly reated to the study drug or local injuries caused by the administration procedure (b) Identify Dose Limiting Toxicity (DLT), if possible (c) Changes in laboratory parameters and vital signs over time vs baseline values
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
AE reported from the first study-related procedure until 30 days following the last dose. DLT from first until last injection of Advince Laboratory efficacy parameters: at baseline (before first treatment), before and after each injection. Biological serum markers before and 24, 48 and 72 h after each treatment. Laboratory safety parameters: - at baseline visit before cycle 1 - at treatment baseline: within 24 hrs before each treatment cycle 2-8 - after each treatment cycle 1-8 (24 h, 48 h and 72 h), - at Evaluation 1 visit - at Evaluation 2 visit - at check-up visits (approximately 8 days after each treatment) - at follow-up visits Local injuries: Checked at each administration of Advince.
|
|
E.5.2 | Secondary end point(s) |
(a) Tumor size and tumor metabolic activity by: - Computer tomography (CT) and/or positron emission tomography (PET) and/or magnetic resonance imaging (MRI) before first and after last treatment cycle - Hormone level screening (biological markers) - Progression-free survival (PFS) 24 weeks after 4th cycle. (b) Viral replication by adenovirus quantification of in patients’ blood on day 1, 8, 22 and 50; before and 24h after injection, as well as 72h after injection by QRT-PCR. (c) Humoral response by detection of anti-adenovirus neutralizing antibodies at baseline, day 8 and day 50.
