Summary
Brief summary (as posted)
The purpose of the study is to determine the appropriate pediatric dosage and evaluate the pharmacokinetics (PK) and safety of Lutetium Lu 177 Edotreotide Targeted Radiopharmaceutical Therapy (RPT) as a monotherapy or following standard of care (SoC) in participants ≥2 to \<18 years of age with somatostatin receptor (SSTR)-positive tumors.

Arms and outcomes
Arms (1)
- type
- EXPERIMENTAL
- label
- Three sequential age cohorts
- description
- Arms are based upon age at enrollment. The opening of the 2nd and 3rd cohort will depend on the recruitment of at least four participants with dosimetry and safety data for cycle 1, in the previous cohort. 1. ≥ 12 to \< 18 years old 2. ≥ 6 years to \< 12 years old 3. ≥ 2 to \< 6 years old
- interventionNames
- Drug: Lutetium Lu 177-Edotreotide
- Other: Amino Acid Solution
Primary outcomes (1)
- measure
- Pediatric Dosage
- timeFrame
- a. Dosimetry assessments will be performed at multiple timepoints in cycle 1, 2 and 4. - b. Minimum of eight weeks after the first administration of Lutetium Lu 177 edotreotide
- description
- Pediatric dosage based on: 1. absorbed dose by target organs (kidney and bone marrow). 2. rate of Dose limitting toxicities - based on adverse event reporting.

Key Inclusion Criteria: * Participants aged ≥ 2 years and \< 18 years * Confirmed diagnosis somatostatin receptor-positive (SSTR-positive) disease. * Tumor which is relapsed or is refractory to at least one line of previous therapy * Positive SSTR protein expression confirmed by immunohistochemistry of a tumor histology sample * Radioactivity uptake within the primary tumor or metastatic tumor sites measured by locally available SRIs ( 111In-based, 99mTc-based, or 68Ga-based SSTR single-photon emission computed tomography (SPECT)/ computed tomography (CT) or positron emission tomography (PET)/CT imaging, which is higher than the liver uptake) * Participants must have recovered from the acute treatment related toxicities (defined as ≤ grade 1 if not defined in eligibility criteria, excluding alopecia, stable treated electrolyte abnormalities on replacement and stable treated hypothyroidism) of all prior treatment modality prior to entering this trial * In case of sequential treatment followed by SoC or prior therapy, washout period applies before starting targeted RPT Screening Consent Participant/legal guardian is willing to sign a screening consent. The screening consent is to be obtained according to institutional guidelines. Assent, when appropriate, will be obtained according to institutional guidelines. Key Exclusion Criteria: * Known hypersensitivity to Lutetium Lu 177 Edotreotide, DOTA/Edotreotide, or excipients * Previous history of acute leukemia unless in remission for at least two years * Extensive bone/bone marrow involvement as per Investigator's judgement unless peripheral blood stem cells (PBSC) are available at a minimum of 2.5x106 CD34+ cells/kg * Patients who have received previous systemic targeted RPT * Previous treatment with metaiodobenzyl guanidine (MIBG) if the predicted overall exposure is expected to exceed 2 Gy (gray) to the bone marrow or 23 Gy to the kidney. * Previous treatment with external beam radiation therapy (EBRT) if the predicted overall exposure is expected to exceed more than 2 Gy to the bone marrow or 23 Gy to the kidney. * Previous treatment with oncologic immune vaccine or CAR-T cell therapy * Bulky disease in the CNS * Presence of severe renal, hepatic, electrolyte, cardiovascular, or hematological dysfunction * Participants who have received a live-attenuated vaccine up to four weeks prior to enrolment * Pregnant or breastfeeding women. * Other known malignancies. * Serious non-malignant disease.
