Inclusion Criteria

1. Written informed consent
2. Subjects 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 subjects 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), functioning and nonfunctioning)
- 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
- subjects, who have histologically confirmed NET, but no clear localization of their primary tumor can be included.
8. Documentation of progressive disease based on RECIST v1.1 under prior anti-tumor therapy within 6 months of Visit 1 Day 1 (although the progression might have occurred more than 6 months before Visit 1 Day1). Subjects should not have received further anti-tumor therapy
once disease progression is documented. All images should be sent to the imaging core laboratory. 9. In countries where sunitinib or everolimus are marketed, patients
with GEP NET and lung NET will be progressive under this prior antitumor
treatment for the respective indication. Subjects not suitable for
everolimus/sunitinib therapy according to a tumor board decision (or
comparable local practice) may also be enrolled into the study. Subjects 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. For Part A: Confirmed presence of somatostatin receptors on technically evaluable tumor lesions documented by a positive SRS* performed within 6 months prior of Visit 1 Day 1

* presence of at least one lesion that is = 20 mm in the longest dimension (as measured on correlative CT or MRI) and with a maximum Standardized Uptake Value (SUVmax) of = 2x the SUVmean of the liver background on 68Ga-PET imaging or a score of 3 or 4 according to the Krenning scale on 111In-SPECT Imaging.

For Part B: Confirmed presence of sstr on technically evaluable tumour lesions documented by a positive SRS*. If this has not been performed within 6 months of Visit 1 Day 1, then it must be repeated during screening.

*presence of at least two lesions that are =20 mm in the longest Dimension (as measured on correlative CT or MRI) with a maximum standardised uptake value (SUVmax) of =2× the SUVmean of the liver background on 68Ga-PET imaging or a score of 3 or 4 according to
the Krenning scale on SPECT Imaging.

12. Calculated glomerular filtration rate (GFR) = 55 mL/min
13. Blood test results as follows:
a. Leukocytes: = 4*10^9/L
b. Erythrocytes: = 3.

Exclusion Criteria

1. Known hypersensitivity to 177Lu, DOTA, JR11 or to any of the
excipients of 177Lu-OPS201.
2. Any previous PRRT.
3. Diagnosis of thymic NET.
4. Presence of active infection at screening, or history of serious
infection within the previous 6 weeks.
5. Administration of any other investigational medicinal product (IMP)
within 60 days prior to entry (Visit 1 Day 1).
6. Prior or planned administration of a therapeutic radiopharmaceutical
within 8 half-lives of the radionuclide including any time during the
current study.
7. Any extensive radiotherapy = 3 months before first IRPP administration.
8. Chemotherapy = 3 months before first IMP administration.
9. For Part B: Nephrectomy, renal transplant or concomitant nephrotoxic therapy putting the subject at high risk of renal toxicity during the study
as assessed by the investigator
10a. Pregnant or breast-feeding women. A serum pregnancy test will be performed
at the start of the study for all female subjects of childbearing potential
(i.e. not surgically sterile or up to 2 years postmenopausal).
11. Any uncontrolled significant medical, psychiatric or surgical condition (active infection (including subject with known hepatitis B or
hepatitis C and subjects with known human immunodeficiency virus
(HIV) positive), unstable angina pectoris, cardiac arrhythmia,
poorly controlled hypertension, poorly controlled diabetes mellitus(glycated haemoglobin (HbA1c) =9%), uncontrolled congestive heart disease, etc.) or
laboratory findings that, in the opinion of the investigator, might
jeopardize the subject's safety or that would limit compliance with the
objectives and assessments of the study. Note: the subject should be
able to tolerate high volume load.
12. Current history of any malignancy other than NET within 5 years of
enrolment except for fully-resected non-melanoma skin cancer or
cervical cancer in situ
13. Any mental condition rendering the subject unable to understand the nature, scope and possible consequences of the study, and/or evidence
of an uncooperative attitude.
