Study Arms (1)

Lu-DOTATATE (Lutathera® ) and olaparib

EXPERIMENTAL

Lu-DOTATATE (Lutathera®) and olaparib for a maximum of 4 cycles unless unacceptable toxic effects occur, there is centrally confirmed disease progression (according to RECIST v1.1/RAPNO/INRC) on imaging, the patient is unable or unwilling to adhere to trial procedures, the patient withdraws consent, or the patient dies. 177Lu-DOTATATE will be administered intravenously, on day 1, every 8 weeks, at a fixed dose of 200 mCi (7.4 GBq) for children \>= 12 years old infused intravenously over a period of 30 minutes. For children younger than 12 years old, the dose that will be administered is 200 MBq per kilogram of body weight (maximum 7.4 GBq) infused intravenously over a period of 30 minutes. Olaparib will be administered PO, BID, days 3-28, every 8 weeks. Dose escalation of olaparib with the classic 3+3 design: DL1 62.5 mg/m2 (max 100 mg); DL2 93.5 mg/m2 (max 150 mg); DL3 125 mg/m2 (max 200 mg).

Drug: Olaparib; 177Lu-DOTATATE

Interventions

7Lu-DOTATATE will be administered intravenously, on day 1, every 8 weeks, at a fixed dose of 200 mCi (7.4 GBq) for children \>= 12 years old infused intravenously over a period of 30 minutes. For children younger than 12 years old, the dose that will be administered is 200 MBq per kilogram of body weight (maximum 7.4 GBq) infused intravenously over a period of 30 minutes. Concomitant to 177Lu-DOTATATE, patients will receive IV fluids and an IV infusion of amino acid solution for renal protection23. Patients will receive four infusions every 8 weeks (maximum cumulative radioactivity, 29.6 GBq \[800 mCi\]). Olaparib will be administered PO, BID, days 2-29, every 8 weeks at a fixed dose of 187.5mg/m2 twice daily (BID).

Eligibility Criteria

Age3 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • months - 18 years of age at the time of the initial diagnosis.
  • Diagnosis: relapsed/refractory solid tumours with positive uptake on SSTR-PET (PET-CT or PET-MRI), performed in the previous three months before entering the study.
  • The evaluation of SSTR expression will be classified according to a qualitative 4-point scale: SSTR expression V (visual score):
  • Score = 0: Below or equal to blood pool
  • Score = 1: Above blood pool and lower than liver
  • Score = 2: Equal to or above liver and lower than spleen
  • Score = 3: Equal to or above spleen
  • Patients with scores ≥ 2 in the majority of the tumoral lesions will be considered to have a positive SSTR-PET and will be therefore eligible for the trial. Patients with a higher score are presumed to have a better response to the treatment.
  • It is admissible to have non-measurable disease only (e.g., HR-NB with bone-only or bone-marrow-only active disease).
  • Performance status ≥ 50% according to Lansky scale (\<16 years old) or Karnofsky scale (for ≥16 years old).
  • Life expectancy of at least 3 months.
  • Availability of ability to swallow tablets or capsules.
  • Adequate organ function within 28 days prior to enrolment, as defined by:
  • Hb ≥10 g/dl (packed red blood transfusion is acceptable up to 24 hours prior starting treatment);
  • White blood cell (WBC) count ≥ 2500/μL (equivalent to 2.5 x 109/L)
  • +11 more criteria

You may not qualify if:

  • Previous significant drug-induced hepatitis toxicity experienced in the past that has required treatment dose reductions, treatment discontinuation or that, at the investigator discretion, could infer a risk.
  • Having received more than one previous treatment with other radiolabelled somatostatin analogues.
  • Inability to swallow tablets or capsules.
  • Subjects who are currently receiving any other anticancer and/or investigational agents (e.g. chemotherapy, immunotherapy or biological therapy \[including monoclonal antibodies\]). There must be at least 28 days of washout from any prior treatment. In case of checkpoints inhibitors, there should be at least 4 months of washout. Palliative Radiation Therapy for symptom control (e.g. pain relief) could be acceptable, at the discretion of the investigator.
  • Treatment with long-acting somatostatin analogues within 28 days prior the administration of 177Lu-DOTATATE.
  • Known hypersensitivity to any of the excipients.
  • Subjects who have an uncontrolled infection.
  • Lactating women.
