- The proportion of patients progression-free using RECIST 1.1 criteria [ Time Frame: Up to 12 months ]
- The overall response rate as determined by structural imaging using RECIST criteria. [ Time Frame: Up to 5 years ]
- The biochemical response rate (as defined by biochemical responses: serum chromogranin A and 24 hr urinary 5HIAA). [ Time Frame: Up to 5 years ]
- The acute and late adverse effects of Lu-DOTATATE (177Lu) using CTCAE Version 4.03 [ Time Frame: Up to 5 years ]
- Overall survival [ Time Frame: Up to 5 years ]
- The Quality of Life (QoL) in patients treated with Lu-DOTATATE (177Lu) [ Time Frame: Up to 5 years ]

|Ages Eligible for Study:||Child, Adult, Older Adult|
|Sexes Eligible for Study:||All|
|Accepts Healthy Volunteers:||No|
Please note that only Ontario residents will be eligible for participation in this trial.
- Biopsy-proven neuroendocrine tumor
- ECOG performance status ≤ 2
- Ki-67 index ≤ 30%
Evidence of progressive disease demonstrated by imaging within six months prior to study enrollment as defined by RECIST v1.1.
- Tumor board discussion of cases to confirm suitability for participation in the clinical trial is required. Review should include but not limited to imaging review, pathology (including Ki 67) and treatment options.
- Patients with objective evidence (imaging, or biochemical) that is insufficient to be classified by RECIST 1.1 criteria can be eligible if after provincial multidisciplinary tumor board discussion a consensus for progression eligibility is reached.
- The tumor board would consider exemptions if the magnitude of change is adequate by other definitions (e.g. using structural and contrast patterns and biochemical changes).
- Where clinically indicated, formal consultation on pathology, diagnostic imaging to facilitate criteria assessment (including 68Ga PET performed as part of the diagnostic procedure) is strongly recommended.
Adequate lab parameters within 2 weeks prior to enrollment:
- Serum creatinine ≤ 150 μmol/L
- Calculated CrCl or measured GFR ≥ 30 mL/min (measured GFR may be done within 4 weeks prior to enrollment)
- Haemoglobin ≥ 90 g/L
- WBC ≥ 2 x 109/L
- Platelets ≥ 100 x 109/L
Adequate liver function tests within 2 weeks prior to enrollment:
- total bilirubin ≤ 5 x ULN
- ALT ≤ 5 x ULN
- AST ≤ 5 x ULN
- alkaline phosphatase ≤ 5 x ULN
- Signed informed consent
- Patients with extensive bone metastases (e.g. >25% of bone marrow involvement are eligible but requires careful monitoring of hematological reserve
- Subject's willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures.
- Age ≥ 18 years.
- Life expectancy <12 weeks
- An option for curative surgical or medical therapy or local liver embolization is feasible
- Candidate for curative and/or debulking surgical resections
- Systemic, biologic, other radioisotope, embolization therapies within ≤4 weeks prior to the first dose of 177Lu.
- Prior radiotherapy to target lesion(s) within ≤12 weeks prior to study enrollment [radiotherapy to non-target lesions permitted].
- Prior therapy with any systemic radionuclide therapy.
- Radiotherapy to more than 25% of the bone marrow.
- Known brain metastases (unless metastases have been treated and are stable for ≥ 6 months).
- Uncontrolled diabetes mellitus
- Co-morbidities that may interfere with delivery of 177Lu (e.g. urinary incontinence).
- Second cancer(s) with clinical or biochemical progression within the last 3 years.
- Pregnancy or breast feeding. Female subjects must be surgically sterile or postmenopausal, or must agree to use effective contraception during the period of therapy. All female subjects with reproductive potential must have a negative pregnancy test (serum) prior to enrolment. Male subjects must be surgically sterile or must agree to use effective contraception during the period of therapy. The definition of effective contraception will be based on the judgment of the principal investigator or a designated associate
- Other condition, illness, psychiatric condition, or laboratory abnormality that may increase the risk associated with study participation, 68Ga or 177Lu administration, or may interfere with the interpretation of study results and in the judgment of the investigator would make the patient inappropriate for entry into this study.
