RECRUITING

Study to Evaluate the Efficacy and Safety of [177Lu]Lu-DOTA-TATE in Patients With Grade 1 and Grade 2 Advanced GEP-NET

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The purpose of the current study is to evaluate the efficacy and safety of \[177Lu\]Lu-DOTA-TATE plus octreotide long-acting release (LAR) versus octreotide LAR alone in newly diagnosed patients with somatostatin receptor positive (SSTR+), well differentiated Grade1 and Grade 2 (G1 and G2) (Ki-67 \<10%) advanced gastroenteropancreatic neuroendocrine tumors (GEP-NETs) with high disease burden

Official Title

A Phase III Multi-center, Randomized, Open-label Study to Evaluate the Efficacy and Safety of [177Lu]Lu-DOTA-TATE in Patients Newly Diagnosed With Grade 1 and Grade 2 (Ki-67 <10%) Advanced GEP-NET With High Disease Burden (NETTER-3)

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:12 Years to 100 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:No
Standard Ages:CHILD, ADULT, OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. * Presence of metastasized or locally advanced, unresectable (curative intent), histologically proven, well differentiated Grade 1 or Grade 2 (Ki-67 \<10%) gastroenteropancreatic neuroendocrine tumor (GEP-NET) diagnosed within 6 months prior to screening.
  2. * Participants with high disease burden in the Investigator's opinion. Following criteria should be used as the guiding principle for determining high disease burden:
  3. * Primary tumor or a metastatic lesion \> 4 cm
  4. * More than one tumor or metastatic lesions measuring \> 2 cm
  5. * Elevated alkaline phosphatase \> 2.5 X upper limit of normal (ULN)
  6. * Presence of bone metastasis
  7. * Presence of peritoneal metastasis
  8. * Symptoms due to tumor volume such as pain, fatigue, weight loss, anorexia etc.
  9. * Symptoms due to hormone excess requiring active management
  10. * Additionally, participants who, in the Investigator's opinion, have high disease burden due to their disease characteristics not specified above could also be considered eligible.
  11. * Participants ≥ 12 years of age.
  12. * RLI somatostatin receptor (SSTR) uptake on all target lesions (defined by RECIST v1.1 criteria) at least as high as normal liver uptake assessed within 3 months prior to randomization. Any of the RLI modalities as available (some examples are listed below) can be used as per local practice:
  13. * \[68Ga\]Ga-DOTA-TOC PET/CT or PET/MRI
  14. * \[68Ga\]Ga-DOTA-TATE PET/CT or PET/MRI
  15. * \[64Cu\]Cu-DOTA-TATE PET/CT or PET/MRI
  16. * Somatostatin receptor scintigraphy (SRS) (planar and/or SPECT/CT) with \[111In\]In-pentetreotide
  17. * SRS (planar and/or SPECT/CT) with \[99mTc\]Tc-octreotide.
  18. * Adequate bone marrow and organ function as defined by the following laboratory values prior to receiving the first study treatment:
  19. * White blood cell (WBC) count ≥ 2 x 109/L
  20. * Platelet count ≥ 75 x 109/L
  21. * Hemoglobin (Hb) ≥ 8 g/dL
  22. * Creatinine clearance \> 40 mL/min calculated by the Cockcroft Gault method
  23. * Total bilirubin ≤ 3 x ULN
  24. * Potassium within normal limits. Potassium level of up to 6.0 millimoles per liter (mmol/L) is acceptable at study entry if associated with creatinine clearance within normal limits calculated using Cockcroft-Gault formula. Mild decrease (grade 1) below lower limit of normal (LLN) is acceptable at study entry if considered not clinically significant by Investigator.
  25. * ECOG performance status 0-1.
  26. * Presence of at least 1 measurable site of disease.
  1. * Prior administration of a therapeutic radiopharmaceutical for GEP-NET at any time prior to randomization in the study.
  2. * Any previous therapy with interferons, mTOR-inhibitors, chemotherapy or other systemic therapies except somatostatin analogues (SSAs) of GEP-NET. If as per Investigator's opinion a participant is candidate for such therapies, such participant must not be enrolled.
  3. * Participant who received more than 4 cycles of prior SSAs (e.g., octreotide long-acting release) are not eligible. In addition, any participant receiving treatment with short-acting octreotide, which cannot be interrupted for 24 h before the administration of \[177Lu\]Lu-DOTA-TATE, or any participant receiving treatment with SSAs, which cannot be interrupted for at least 4 weeks before the administration of \[177Lu\]Lu-DOTA-TATE.
  4. * Documented RECIST v1.1 progression during previous SSA treatments for the current GEP-NET at any time prior to randomization.
  5. * Any previous radioembolization, chemoembolization and radiofrequency ablation for GEP-NET.
  6. * Any major surgery within 12 weeks prior to randomization in the study.
  7. * Known brain metastases.
  8. * Participant with known intolerance to CT scans with intravenous (i.v.) contrast due to allergic reaction or renal insufficiency. If such a participant can be imaged with MRI, then the participant would not be excluded.
  9. * Hypersensitivity to any somatostatin analogues, to the Investigational Medicinal Products (IMPs) active substance or to any of the excipients.
  10. * Active severe urinary incontinence, severe voiding dysfunction, or urinary obstruction requiring an indwelling/condom catheter that, in the judgment of the Investigator, could prevent adhering to radiation safety instructions.
