Essai de phase I pour déterminer la dose et évaluer la pharmacocinétique du traitement par lutétium Lu 177 édotréotide chez les participants pédiatriques atteints de tumeurs SSTR-positives (KinLET)
Un essai interventionnel multicentrique ouvert de phase I pour déterminer la dose et évaluer la pharmacocinétique (PK) et l'innocuité de la thérapie radiopharmaceutique ciblée (RPT) par lutétium Lu 177 édotréotide en monothérapie ou selon la norme de soins (SoC) pour le traitement de la somatostatine Tumeurs à récepteurs positifs dans la population pédiatrique (KinLET).
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.

Description détaillée
Determine the dose, pharmacokinetics and safety of Lutetium Lu 177 Edotreotide as monotherapy or following sequential standard of care in pediatric participants with recurrent, progressive or refractory NET, CNS, lymphoma and other solid tumors that express SSTRs by immunohistochemistry and demonstrate uptake by somatostatin receptor imaging. Lutetium Lu 177 Edotreotide will be given intravenously once every 8 weeks for a total of up to 6 doses over an average of 48 weeks in participants aged 2-18 years.

La description
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

Expérimental: Three sequential age cohorts
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.
|
lutetium Lu 177 edotreotide At least two cycles and a maximum of six cycles at eight-week (± 2 we-ek) intervals. Extrapolation from standard maximum adult dose of 100 Megabecquerel(MBq)/kg for a 75 kg adult for the first cohort. Dosing decision for the subsequent cohorts by Data Monitoring Committee (DMC), based on (at least) cycle 1 dosimetry and safety data from at least four participants of the preceding cohort. Route of administration: Intravenous (IV) infusion. Duration of treatment: 16-48 weeks
Autres noms:
The Amino-Acid Solution (AAS) to be used in this study will contain a mixture of lysine and arginine diluted in an electrolyte solution.
