Experimental: 177Lu-OPS201
177Lu-OPS201 will be administered in 3 cycles at intervals of 8 weeks (+ up to 2 additional optional cycles)
Drug: Satoreotide tetraxetan

Other Name: 177Lu-OPS201

Other: Amino acid solution

Given as an auxiliary product the day of the IMP infusion for safety reasons to protect the renal function.

Centres can use their established amino acid infusion or Ipsen amino acid solution (auxiliary medical product OPS301)

Other Name: OPS301

Other: Antiemetic
To counteract the known side effects of the amino acid infusion, such as nausea, dexamethasone (antiemetic) and as-required ondansetron will be administered 15 to 30 minutes before the start of the amino acid infusion (unless there are contraindications for these drugs).
Other Names:

Primary Outcome Measures :
  1. Safety and Tolerability of 177Lu-OPS201 assessed by number of patients with treatment related adverse events using CTCAE v5.0 [ Time Frame: during the whole study period of 34 months ]

Secondary Outcome Measures :
  1. Area under the curve (AUC) of 177Lu-OPS201 per cycle in discernible thoracic and abdominal organs, target lesions and blood [ Time Frame: during the core study period of 10 months ]
  2. Maximal uptake (achieved in %) at the target lesions per cycle. [ Time Frame: during the core study period of 10 months ]
  3. Maximal uptake in discernible organs (%) and blood (%/mL) per cycle. [ Time Frame: during the core study period of 10 months ]
  4. Organs receiving the highest absorbed dose (Gy) for each cycle. [ Time Frame: during the core study period of 10 months ]
  5. Specific absorbed dose per organ (achieved in Gy/GBq) for each cycle. [ Time Frame: during the core study period of 10 months ]
  6. Cumulative absorbed organ doses (achieved in Gy). [ Time Frame: during the core study period of 10 months ]
  7. Preliminary therapeutic efficacy of 177Lu-OPS201 assessed by tumor response based on RECIST v1.1 [ Time Frame: during the whole study period of 34 months ]
  8. Preliminary therapeutic efficacy of 177Lu-OPS201 assessed by monitoring of PFS (based on RECIST v1.1 status) [ Time Frame: during the whole study period of 34 months ]
  9. Quality of Life (QoL) questionnaire [ Time Frame: during the core study period of 10 months ]
  10. Terminal half-life of radioactivity concentrations of the radiopharmaceutical in blood [ Time Frame: during the first 7 days of cycle 1 of the core study period ]
  11. PK parameters of OPS201, if OPS201 levels are measurable in plasma and urine. [ Time Frame: during the first 3 days of cycle 1 of the core study period ]
    PK parameters of OPS201(including, but not limited to, maximum observed concentration (Cmax), AUC, elimination half-life (t1/2), apparent total body clearance of the drug from plasma (CL), apparent volume of distribution (Vd), cumulative amount of unchanged drug excreted into the urine (Ae), renal clearance of the drug from plasma (CLR)) will be derived using the non-compartmental approach on the individual plasma concentration-time profiles of OPS201 and on the individual urine concentrations

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

Inclusion Criteria:

  1. Written informed consent.
  2. Patients of either gender, aged ≥ 18 years.
  3. Women of childbearing potential (not surgically sterile or less than 2 years postmenopausal) must use a medically accepted method of contraception and must agree to continue use of this method for the duration of the study and for 6 months after the last dose. Acceptable methods of contraception include abstinence, or double contraception: steroidal contraceptive (oral, transdermal, implanted, and injected) in conjunction with a barrier method (intrauterine device, condom etc.).
  4. Male patients must use a medically accepted method of contraception and must agree to continue use of this method for the duration of the study and for 6 months after the last activity administration.
  5. Karnofsky performance score ≥ 60.
  6. Life expectancy of at least 6 months.
  7. Histologically confirmed diagnosis of -

    • unresectable GEP NET (Grade I and Grade II according to WHO classification (2010, Annex 01), functioning and non-functioning).
    • unresectable "typical lung carcinoid" or "atypical lung carcinoid" are acceptable (with the exception of Large Cell Bronchial Neuroendocrine Neoplasms and Small Cell Lung Cancers) (Caplin 2015).
    • malignant, unresectable pheochromocytoma or paraganglioma
  8. Documentation of progressive disease based on RECIST v1.1 under prior anti-tumor therapy within 6 months of entry in the study (although the progression might have occurred more than 6 months before study entry). Patients should not have received further anti-tumor therapy once disease progression is documented. The images of this evaluation should be available for TGR evaluation.
  9. In countries where sunitinib or everolimus are marketed, patients with GEP NET and lung NET will be progressive under this prior anti-tumor treatment for the respective indication. Patients not suitable for everolimus/sunitinib therapy according to a tumor board decision (or comparable local practice) may also be enrolled into the study. Patients having everolimus/sunitinib therapy should have a wash-out phase of ≥ 4 weeks before the first treatment.
  10. Measurable disease based on RECIST v1.1.
  11. Confirmed presence of somatostatin receptors on technically evaluable tumor lesions documented by a positive Somatostatin Receptor Scan performed within 6 months prior to enrolment in the study.

  13. Blood test results as follows:

    • Leukocytes: ≥ 4*10^9/L
    • Erythrocytes: ≥ 3.5*12^9/L

  11. Any uncontrolled significant medical, psychiatric or surgical condition (active infection, unstable angina pectoris, cardiac arrhythmia, poorly controlled hypertension, poorly controlled diabetes mellitus [HbA1c ≥9%], uncontrolled congestive heart disease, etc.) or laboratory findings that, in the opinion of the investigator, might jeopardize the patient's safety or that would limit compliance with the objectives and assessments of the study. Note: the patient should be able to tolerate high volume load.
