Phase I Trial to Determine the Dose and Evaluate the PK and Safety of Lutetium Lu 177 Edotreotide Therapy in Pediatric Participants With SSTR-positive Tumors
Trial Parameters
Brief Summary
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.
Eligibility Criteria
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 fo
