RECRUITING
A Trial to Assess the Safety and Effectiveness of Lutetium-177 Octreotate Therapy in Neuroendocrine Tumours
Lead Sponsor:
AHS Cancer Control Alberta
Conditions:
Carcinoma, Neuroendocrine
Eligibility:
All Genders
14-90 years
Phase:
PHASE2
Brief Summary
Neuroendocrine tumours (NETs) are rare, slow growing, and diagnosis is often delayed with advanced metastases at presentation. In select patient populations, radioisotope therapy with Lutetium-177 (Lu...
Detailed Description
The proposed clinical trial will be a Phase II, open label, single site study in subjects with somatostatin receptor positive tumours. Radioactive Lu-DOTA-TATE doses are fixed within a range of 1.85 -...
Eligibility Criteria
Inclusion
- Group A (Primary Therapy)
- Male or female ≥ 14 - 90 years of age.
- At least 1 tumour site reliably evaluable by CT or magnetic resonance imaging (MRI) of at least 1.0 cm (smallest dimension) or ≥ 1.5 cm lymph node disease (smallest dimension) (the target lesion) within 26 weeks of enrolment, with documented presence of somatostatin receptors on radionuclide imaging, with uptake greater than liver background as assessed by planar Octreoscan® images or Ga-68 labelled somatostatin analogue (68Ga-DOTATATE or 68Ga-HA-DOTATATE) PET imaging (or other available somatostatin receptor targeting PET agents) obtained within 1 year of enrolment. Patients with bone-only disease can be enrolled provided there is presence of somatostatin receptor positive tumour(s) on radionuclide imaging corresponding to osteolytic or osteoblastic bone lesions on CT or MRI, with uptake greater than liver background as assessed by planar Ocgtreoscan(R) images or somatostatin receptor PET imaging regardless of size.
- Histologically confirmed diagnosis of neuroendocrine tumor.
- Progressive disease documented by anatomic imaging and/or presence of new lesions on somatostatin receptor imaging assessed by comparable studies. In the opinion of the investigator, patients with no progression on imaging may still be considered eligible in presence of carcinoid symptoms refractory to treatment with somatostatin receptor analogues or functional Pheochromocytoma/Paraganglioma symptoms that are not well controlled with current medical treatment.
- 18F-FDG PET/CT whole-body imaging within 26 weeks of enrolment.
- Life expectancy greater than 12 weeks from enrollment.
- Serum creatinine ≤ 150 µmol/L, and a calculated (Cockcroft-Gault) or estimated GFR of ≥ 50 mL/min measured within 2 weeks of enrollment.
- Haemoglobin concentration ≥ 90 g/L; white blood cell (WBC) count ≥ 2 x 10\^9/L; platelets ≥ 100 x 10\^9/L measured within 2 weeks of enrolment.
- Liver function tests (total bilirubin, alanine transaminase (ALT), aspartate transaminase (AST)) ≤ 3X the limit of normal measured within 2 weeks of enrolment. Serum albumin ≥ 23 g/L within 2 weeks of enrolment.
- Eastern Cooperative Oncology Group (ECOG) Performance Scale Score ≤ 2 measured within 2 weeks of enrolment.
- Provide written informed consent prior to enrolment.
- Group B (Maintenance Therapy)
- Male or female ≥ 14 - 90 years of age.
- Have previously received Lu-DOTA-TATE treatment under the SAP.
- Life expectancy greater than 12 weeks from enrolment.
- Serum creatinine ≤ 150 μmol/L, and a calculated (Cockcroft-Gault) or estimated glomerular filtration rate (GFR) of ≥ 50 mL/min measured within 2 weeks of enrolment.
- Haemoglobin concentration ≥ 90 g/L; white blood cell (WBC) count ≥ 2 x 10\^9/L; platelets ≥ 100 x 10\^9/L measured within 2 weeks of enrolment.
- Liver function tests (total bilirubin, alanine transaminase (ALT), aspartate transaminase (AST)) ≤ 3X the limit of normal measured within 2 weeks of enrolment. Serum albumin ≥ 23 g/L within 2 weeks of enrolment.
- Eastern Cooperative Oncology Group (ECOG) Performance Scale Score ≤ 2 measured within 2 weeks of enrolment.
- Provide written informed consent prior to enrolment.
- Group A (Primary Therapy)
Exclusion
- Have previously received Lu-DOTA-TATE therapy.
- Potential for surgery with curative intent. Local surgery for symptomatic relief permitted as long as target lesion unaffected.
- Major surgery within 12 weeks of enrolment. Minor surgeries such as removal of superficial skin lesions, laser eye surgery, cataract surgery, laparoscopic procedures and other procedures that are minimally invasive are permitted at the Investigator's discretion.
- Liver embolization \[transcatheter arterial embolization (TAE), TACE, or TARE\] within 4 weeks of enrolment.
- Radioisotope therapy within 12 weeks of enrolment.
- Systemic therapy: mTOR inhibitors and tyrosine kinase inhibitors within 6 weeks of enrolment; chemotherapy and interferon within 8 weeks of enrolment.
- Change in long-acting somatostatin analogues, dosage, or dosage frequency within 12 weeks of enrolment unless changes are required to manage uncontrolled symptoms.
- Localized external beam irradiation with target lesion(s) in the radiation field. Other localized external beam therapy is permitted.
- Known brain metastases unless these metastases have been treated and stabilized (confirmed by CT) for ≥ 4 months prior to enrolment
- Uncontrolled diabetes mellitus defined as random glucose ≥ 2X the upper limit of normal (or HbA1c \> 10%, if results available) within 12 weeks of enrolment.
- Another significant medical, psychiatric or surgical condition uncontrolled by treatment, which may interfere with completion or conduct of the study (such as urinary incontinence, co-existing malignancies).
- Pregnancy.
- Breast feeding.
- Prior radiation therapy to more than 25% of the bone marrow.
- If, in the opinion of the investigator, other treatments are considered more appropriate than the investigational therapy, based on patient and disease characteristics.
- Known allergy to somatostatin analogues or any components of the study medication.
- Group B (Maintenance Therapy)
