Brief Summary:
Randomized Phase II Trial in sstr2 Positive Tumors to Optimize the Interval Between Cycles of PRRT With 177lu-dotatate

Condition or disease Intervention/treatment Phase
Neuroendocrine Tumors Drug: PRRT every 5 weeks Drug: PRRT every 8-10 weeks Phase 2

Detailed Description:

The main objective of this randomized phase II comparative study is to evaluate the Progression Free survival (PFS) and the safety as co-primary objective of two different schedule of administrations of 177lu-dotatate: intensive (every 5 weeks) vs no intensive (every 8-10 weeks) The secondary objectives are DCR, the late toxicity, OS and dosimetry. Patients with any tumor histotype documented as sst2-positive in pre-study period will be enrolled in the study.

The study will include a total of 618 planned patients. They will be randomly assigned to receive 5 cycles of PRRT at intervals of 5 or 8-10 weeks between cycles.

Arm Intervention/treatment
Experimental: Arm A, Intensive
Arm A, Intensive every 5 weeks
Drug: PRRT every 5 weeks
PRRT (radiolabelled somatostatin analogues) every 5 weeks for 5 cycles

Experimental: Arm B, Non Intensive
Arm B, Non Intensive every 8-10 weeks
Drug: PRRT every 8-10 weeks
PRRT (radiolabelled somatostatin analogues) every 8-10 weeks for 5 cycles




Primary Outcome Measures :
  1. PFS [ Time Frame: up to 5 years ]
    Progression free survival is defined as the time from the randomization date to the date of first observation of documented disease progression or death due to any cause

  2. Incidence of Treatment-Emergent Adverse Events [ Time Frame: up to 30 days after last treatment cycle ]
    The evaluation of Treatment-Emergent Adverse Events, defined as any G3/G4 toxicity from 1st treatment cycle until 30 days after the last treatment cycle will be based on version 4.0 CTC-AE


Secondary Outcome Measures :
  1. DCR [ Time Frame: up to 5 years ]
    Disease Control Rate (DCR) is defined as the percentage of patients who have achieved complete response, partial response and stable disease for at least 12 weeks from therapy start. DCR will be evaluated using the new international criteria proposed by the Version 1.1 Response Evaluation Criteria in Solid Tumors (RECIST)

  2. OS [ Time Frame: up to 5 years ]
    Overall Survival (OS) is defined as the time from treatment start to the time of death due to any cause or the date of last contact (censored observation) at the date of data cut-off.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Age >18 years.
  2. Patients must have histologically or cytologically confirmation of neuroendocrine tumors or any other tumor histology type documented as sst2-positive (, that may benefit from receptor radionuclide therapy and for which there aren't any other effective treatments.
  3. Measurable disease according to RECIST 1.1.criteria also patients without measurable but with evaluable disease disease can be enrolled.
  4. Any disease stage is allowed. Patients with documented disease will be admitted to therapeutic phase only if the diagnostic OctreoScan (the tumour uptake will be evaluated with a 3-grade scale, where 1 = liver uptake, 2 > liver uptake and < kidney uptake and 3 > kidney uptake: only tumour uptakes grade 2 and 3 will be considered for therapy) and/or Positron Emission Tomography (PET)/CT 68Ga-peptide images demonstrate a significant uptake in the tumour.
  5. Patients with progressive disease in pre-study period (PD within the last 12 months), refractory to conventional standard treatments; clinical progression is allowed
  6. Patients with or without concurrent therapy with somatostatin analogs
  7. Life expectancy of greater than 6 months.
  8. Eastern Cooperative Oncology Group (ECOG) performance status <2
  9. Adequate haematological, liver and renal function: haemoglobin >= 9 g/dL, absolute neutrophil count (ANC) >= 1.5 x 109 /L, platelets >= 100 x 109 /L, bilirubin ≤1.5 X upper normal limit (UNL) , alanine aminotransferase ( ALT) and Aspartate aminotransferase (AST) <2.5 X UNL (< 5 X UNL in presence of liver metastases, creatinine < 2 mg/dL.
  10. If female of childbearing potential highly effective birth control methods, according to guideline "Recommendation related to contraception and pregnancy testing in clinical trials", (2014_09_15 section 4.1) are mandatory.
  11. Participant is willing and able to give informed consent for participation in the study.

Exclusion Criteria:

  1. Patients treated with chemotherapy and therapeutic radiotherapy within 4 weeks and treated within 2 weeks with palliative radiotherapy, hormonal or biological therapy.
  2. Patients treated with previous radio-metabolic therapy with an adsorbed dose to the kidney more than 23 Gy and more than 1.8 Gy for the bone marrow or as surrogate of dosimetry (13).
  3. All acute toxic effects of any prior therapy (including surgery radiation therapy, chemotherapy) must have resolved to a grade ≤ 1 according to National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0 (CTCAE)
  4. ECOG performance status >2
  5. Participation in another clinical trial with any investigational agents within 30 days prior to study screening.
  6. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
  7. Assessed bone marrow invasion > 50% (with Bone Marrow biopsy or instrumental exams i.e bone scan or CT or MRI)
  8. Pregnant or breastfeeding women are excluded from the present study.
