Study in children and adolescents of 177Lu DOTATATE (Lutathera®) combined with the PARP inhibitor olaparib for treatment of recurrent or relapsed solid tumours expressing somatostatin receptors (SSTR) (LuPARPed)
Relapsed/refractory (R/R) solid tumours at the paediatric age have a dismal prognosis [5-year overall survival (OS) less than 20%. There is growing evidence about the somatostatin receptor (SSTR) expression in paediatric tumours, which opens a new diagnostic and therapeutic tool. Somatostatin receptor-targeted therapy with 177Lu-DOTA0-Tyr3-octreotate (177[Lu]Lu DOTA-TATE, 177Lu-DOTATATE, Lutathera®) has been approved by the EMA (2017) and the FDA (2018) for the treatment of adults with midgut neuroendocrine tumours after the excellent results achieved in the phase III NETTER-1 study.
177Lu-DOTATATE is already being explored as monotherapy in children with R/R high-risk neuroblastoma, CNS tumours or meningiomas in 2 pilot studies and 4 clinical trials (ISRCTN98918118, NCT04903899, NCT03966651, NCT05278208). There are two on going clinical trials exploring the recommended phase 2 dose (RP2D) of 177Lu-DOTATATE in children younger than12 years old, but results are still pending.
The results show promising but insufficient results. Because of its beta particle emission, 177Lu-DOTATATE mainly produces DNA single-strand breaks (SSBs) that are easily repaired by the organism. In order to enhance its effect, the investigators propose its combination with PARP inhibitors (iPARP) so that the SSBs could not be repaired and would lead to the formation of DNA double strand breaks (DSBs) and, subsequently, to cell death. This combination is already being explored in different clinical trials in adults with neuroendocrine tumours and prostate cancer. An interesting study analysed the perfect scheme for the 177Lu-DOTATATE and olaparib combination and concluded that olaparib should be delayed 24 hours after 177Lu-DOTATATE administration in order to facilitate normal tissue repair without decreasing antitumoural activity. It also concludes that there is no benefit in continuing olaparib after 4 weeks of continuous treatment. Olaparib has also been administered in children and there is today a recommended phase 2 dose (187.5 mg/m2 BID).
The 177LUDOTATATE and olaparib combination is already being explored in different clinical trials in adults with neuroendocrine tumors and prostate cancer 19-21. One of these studies (NCT04375267) has already published results, showing that, when combined with 177LUDOTATATE, olaparib recommended starting dose is 200 mg BID instead of the normal 300 mg BID dose.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
The evaluation of SSTR expression will be classified according to a qualitative 4-point scale: SSTR expression V (visual score):
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- only (e.g., HR-NB with bone-only or bone-marrow-only active disease).

Exclusion criteria
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.
Studies often ask for 60 or 70 and above. Your doctor gives the score.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.
Criteria about it usually ask for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
