A Phase 2 interventional study of Temozolomide and Irinotecan in Pineoblastoma, sponsored by University of Regensburg. Completed at 1 site in Germany. Open to participants aged 0 Years to 25 Years. Per ClinicalTrials.gov, last updated 2021-08-05.
Sponsored by University of Regensburg · Phase 2, Interventional, and Treatment
Children, adolescents and young adults with relapsed or treatment refractory pineoblastoma (rPB) represent a group of patients with dismal prognosis for whom a recommended standard salvage therapy is currently not available.
The multimodal metronomic approach combining molecular targeted drugs (rapamycin and dasatinib) with conventional chemotherapy (irinotecan and temozolomide) will be investigated in a randomized fashion as new treatment strategy for patients with rPB. The intention is to assess the therapeutic benefit of molecular targeted drugs for the treatment of rPB.
The combination of irinotecan and temozolomide showed activity in the treatment of several solid organ tumors, brain tumors and neuroblastoma. In one study relapsed neuroblastoma (rNB) patients received a median of 5 courses of 5 days irinotecan and temozolomide every 3 to 4 weeks with a cumulative dose of 35% lower than in the RIST design. 33% had disease regression with 8% CR or PR. A phase II study in rNB also using irinotecan and temozolomide with a substantially lower intensity showed a response rate of 15%.
The combination of a mTOR inhibitor with a multi-kinase inhibitor demonstrated in preclinical studies a synergistic effect on cell cycle arrest, apoptosis and sensitization for radio- and chemotherapy. It is assumed that this combination of molecular targeted drugs with a tolerable conventional chemotherapy consisting of irinotecan and temozolomide can substantially improve the outcome of this patient population. A group of 20 rNB patients treated with the RIST therapy approach in a compassionate use setting showed an overall survival of 55% at a median of 80 weeks with a tolerable adverse event profile.

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.
Patients with high-grade pineoblastome (=rPB) and all of the following criteria will be considered for admission to the clinical trial:
Patients are required to have an (ANC) ≥500/µL, ≥8g/dL (transfusion permitted), and an unsupported count ≥30,000/µL unless:
Exclusion Criteria:
Patients presenting with any of the following criteria will not be included in this clinical trial:
12-lead with QTc>500 msec / QTc>60 msec baseline
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.
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.
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.
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.
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.
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).
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.
On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.
The study may name a correction formula and a limit in milliseconds, often around 450–480.
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.
Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
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.
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.
A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
