  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Histopathologic diagnosis of inoperable or metastatic gastro-entero-pancreatic neuroendocrine neoplasia.

About this study

The aim of this phase I-II study is to evaluate the efficacy and toxicity of PRRT with 177Lu-DOTATATE (Lu-PRRT) associated to metronomic chemotherapy with Capecitabine in patients affected by aggressive FDG-positive gastro-entero-pancreatic NET. Moreover to analyze the effects of the capecitabine metronomic schedule on the level of circulating angiogenetic factors.

Read the detailed description

Neuroendocrine tumors (NETs) are relatively rare tumors, mainly originating from the digestive system, able to produce bioactive amines and hormones. NETs tend to be slow growing and are often diagnosed when metastatic. Treatment is multidisciplinary and should be individualized according to the tumor type, burden, and symptoms. Therapeutic tools include surgery, interventional radiology, and medical treatments such as somatostatin analogues, interferon, chemotherapy, new targeted drugs (everolimus, sunitinib) with radiolabelled somatostatin analogues. Despite the options available, antiproliferative treatment options for patients with inoperable gastro-entero-pancreatic (GEP) NETs are limited.

PRRT with radiolabelled somatostatin analogues 90Y-DOTATOC, and 177Lu-DOTATATE (177Lu-DOTA-D-Phe1-Tyr3-octreotate), has been experimented for more then 15 years in few centers. The introduction of PRRT and, particularly, the advent of 177Lu-DOTATATE, broke through the poor scenario of available treatment for NETs.

Dosimetric studies demonstrated that 90Y-DOTATOC and 177Lu-DOTATATE are able to deliver high radiation doses to somatostatin receptor sst2-expressing tumors and low doses to normal organs. Clinical studies demonstrated that partial and complete objective responses in up to 30% of patients can be obtained, with a great survival benefit including those with stable disease. Side effects may involve the kidney and the bone marrow and are usually mild. Renal protection is used to minimize the risk of a late decrease of renal function.

Recently, in order to further increase the objective response to PRRT, a combined treatment with the radiosensitizer capecitabine, has been proposed and tested on GEP-NET patients' population. Capecitabine is the oral prodrug of 5-fluorouracile (5-FU), which is active in GEP tumors and a radiosensitizer itself. The finding that neo-angiogenesis can be shut down also with cytotoxic drugs like capecitabine when administered in low and frequent doses, constitutes the rationale for proposing a particular schedule of chemotherapy that is, therefore, named "metronomic" or "anti-angiogenic".

Based on the reported experience, the investigators think to offer a combined therapy in aggressive, metabolically active tumors, such as those patients with a positive FDG scan. FDG-PET allow the investigators to obtain in vivo imaging of increased glycolysis which is known to be an hallmark of tumor aggressiveness.

The aim of this phase I-II study is to evaluate the efficacy and toxicity of PRRT with 177Lu-DOTATATE (Lu-PRRT) associated to metronomic chemotherapy with Capecitabine in patients affected by aggressive FDG-positive gastro-entero-pancreatic NET. Moreover to analyze the effects of the capecitabine metronomic schedule on the level of circulating angiogenetic factors.

    Patients without risk factors (particularly long standing and poorly controlled diabetes and hypertension) for late renal toxicity will be administered with 5 cycles of 5.5 GBq (150 mCi) each, up to the total cumulative activity of 28 GBq (750 mCi) of 177Lu-DOTATATE.

  • 22 GBq 177Lu-DOTATATEDrug

    Patients with risk factors for late renal toxicity will be administered with 6 cycles of 3.7 GBq (100 mCi) each, up to the total cumulative activity of 22 GBq (600 mCi)177Lu-DOTATATE

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing 28 GBq 177Lu-DOTATATE and 22 GBq 177Lu-DOTATATE in people with Neuroendocrine Tumors and Gastro Entero Pancreatic Neuroendocrine Tumors, run by Istituto Romagnolo per lo Studio dei Tumori Dino Amadori IRST S.r.l. IRCCS at 2 sites in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Objective Overall Response Rate (time frame: up to 24 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jan 2025.
