Study Details

Study Description

Brief Summary

Lu-DOTA-TATE (Lutetium-177 octreotate) is a radiopharmaceutical that has been reported as being effective in controlling symptoms and increase quality of life; induce stable disease and extend progression free survival; induce a (good) partial remission and induce a complete remission in patients with a somatostatin receptor positive tumour.

The purpose of this study is to assess the efficacy of Lu-DOTA-TATE by measuring progression free survival and overall survival. This study will also asses the safety of Lu-DOTA-TATE, and the quality of life of the patients treated with Lu-DOTA-TATE.

Phase 2

Detailed Description

Neuroendocrine (NET) tumours have secretory and metabolic pathways not typically found in other cancers that can be utilized for molecular imaging and therapeutic targeting. The most important is somatostatin. Somatostatin receptors are useful tools in the diagnosis and treatment of NET tumours because the somatostatin analogue octreotate can be radiolabeled with lutetium-177 for imaging and therapy.

In selected populations of patients, radioisotope therapy in expert hands has been shown to be a safe and effective palliative therapy with stable disease, progression free survival benefit, symptom control and improvements in quality of life. Lutetium-177 (DOTA0, Tyr3) octreotate has been used in a significant number of clinical studies shown to be safe and effective as a therapeutic agent in patients with NET tumours. The investigators intend to further confirm these benefits with lutetium-177 octreotate, which could form the basis for a national registry study leading to registration of this therapeutic intervention.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Primary Therapy with Lu-DOTA-TATE

Lu-DOTA-TATE (Lutetium-177 Octreotate) will be administered by intravenous infusion to participants who have not been previously treated with Lu-DOTA-TATE

Other: Lu-DOTA-TATE
Other Names:
  • Lutetium-177 Octreotate
  • radiopharmaceutical
  • Experimental: Secondary Therapy with Lu-DOTA-TATE

    Patients who have received previous treatment with Lu-DOTA-TATE (Lutetium-177 Octreotate) under the special access program are eligible to be treated in this study. Patients will receive Lu-DOTA-TATE by intravenous infusion.

    Other: Lu-DOTA-TATE
    Other Names:
  • Lutetium-177 Octreotate
  • radiopharmaceutical
  • Outcome Measures

    Primary Outcome Measures

    1. Tumour response measured by RECIST criteria [7 years (end of study)]

      Target lesions will be assigned after treatment 1 base done either the Lu-177 scan, or the CT/MRI scan within 2 weeks prior to treatment 1. Tumour response will be measured using response evaluation criteria in solid tumours (RECIST).

    Secondary Outcome Measures

    1. Progression Free Survival [7 years (end of study)]

      Progression free survival will be measured from the date of enrollment to the date the target lesion progresses as per RECIST criteria, or death sue to any cause.

    2. Quality of Life [7 years (end of study)]

      Quality of life changes due to treatment with Lu-DOTA-TATE, measured using the European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaire(QLQ) EORTC QLQ-C30.

    2. Presence of somatostatin receptor positive tumour(s) (either histologically or Octreoscan image proven), with at least 1 tumour site reliably evaluable by CT or MRI of at least 1.5 cm (smallest dimension) with respect to RECIST criteria (the target lesion).

    3. Presence of somatostatin receptors on (at least) the target lesion demonstrated by uptake of OctreoScan® at least equal to liver uptake within 12 weeks of enrollment.

    4. Life expectancy greater than 26 weeks from enrollment.

    5. Serum creatinine ≤ 130 μmol/L, and a measured glomerular filtration rate (GFR) using plasma clearance of ≥50 mL/min measured within 2 weeks of enrollment.

    7. Liver function tests (serum albumin, total bilirubin, alanine amniotransferase (ALT),aspartate aminotransferase (AST) and alkaline phosphatase) ≤ 3 X the limit of normal.

    8. Eastern Cooperative Oncology Group (ECOG) Performance Scale Score ≤ 2 measured within 2 weeks of enrollment.
