HIT-MED Trial office

  • After leukemia, brain tumors are the second most frequent malignant disease in children and adolescents. There are approximately 400 patients diagnosed with a brain tumor every year. Although the chance of cure has increased during the last years significantly and today approximately 80% of the patients can expect long-term survival after diagnosis of a brain tumor in childhood, the results of current therapy are not satisfactory. While the survival still needs to be improved, at the same time the long-term side effects of both the disease and the treatment need to be improved.On behalf of the society for pediatric hematology and oncology (Gesellschaft für Pädiatrische Onkologie und Hämatologie, GPOH), the HIT-MED trial office coordinates clinical research projects on medulloblastoma, ependymoma and different other malignant, very rare brain tumors of childhood and adolescence.The HIT-MED trial office, we dedicate our work to

    • the development and optimization of treatment concepts (operation, radiotherapy, chemotherapy) for patients with these brain tumors
    • the development and maintenance of systems for central reference centers for children with brain tumors.
    • counselling of physicians in participating centers in the treatment of the above mentioned brain tumors.

    The HIT-MED trial office coordinates several clinical research projects:

    SIOP Ependymoma II
    SIOP High-Risk Medulloblastoma (HRMB)
    PNET5
    HIT2000
    I-HIT-MED Registry
    Neuropsychological co-study

    The German Reference Centre for CSF diagnostics is also located at the university medical centre in Hamburg:
    German Reference Centre CSF diagnostics

    The HIT-MED trial office receives funding from the German childhood cancer foundation (www.kinderkrebsstiftung.de ), the "Fördergemeinschaft Kinderkrebs-Zentrum Hamburg e.V." (www.kinderkrebs-hamburg.de ) and the Damp-Foundation (www.damp-stiftung.de).

  • Not all patients with brain tumors can be included into clinical trials for various reasons. Either because such a trial is not available in the hospital the patient or his representatives have chosen or because patients prefer standard treatment. However, many of these patients are open to participate in research activities. Therefore, the HIT-MED trial office has opened an international registry for patients with

    • Medulloblastoma
    • Ependymoma
    • Tumos of the pineal region.
    Patients of < 22 years of age at initial diagnosis can be registered in the I-HIT-MED registry with the aim to collect both clinical data and biological data and analyse these with the aim to increase our knowledge on clinical courses and tumor biology.
    Moreover, the I-HIT-MED registry database will help us when counselling physicians in how to select the optimal treatment for their patients.

    Please note that patient inclusion is currently not possible due to temporary suspension of recruitment.

  • SIOP Ependymoma II is a multicenter phase II/III clinical trial to optimize the therapy for children and adolescents with ependymoma. To be included, patients need to be no older than 21 years at initial diagnosis.

    Pierre Leblond, Lyon, France, is the international coordinating investigator. For Germany, Stefan Rutkowski, Hamburg, Germany is the national coordinating investigator.

    Patients will be stratified into different strata according to age, tumor localization and extent of resection, The aims differ according to the respective stratum:

    Stratum 1:

    In patients > 12 months of age and with complete tumor resection, can maintenance chemotherapy administered after standard radiotherapy reduce the risk of relapse?

    Stratum 2:

    In patients > 12 months of age and with relevant residual tumor, can the addition of MTX to VEC chemotherapy (MTX + VEC) provide a benefit compared to VEC chemotherapy alone?

    In patients > 12 months of age and with relevant residual tumor, can a boost to the region of the residual tumor provide a benefit for the control of tumor growth? Which effects exhibits this boost on survival and quality of life?

    Stratum 3:

    In patients < 12 months of age, can the addition of Valproate to chemotherapy alone reduce the risk of relapse?

    As secondary objective, questions on tumor biology and various late effects (e.g. quality of survival, neuropsychological follow-up) will be addressed.

    ClinicalTrials.gov ID: NCT02265770

  • SIOP HRMB is a multicentric phase III clinical trial to optimize the therapy of children and adolescents with high-risk medulloblastoma. To be included, patients need to be older than 3 years of age at initial diagnosis.

    Simon Bailey, Newcastle upon Tyne, Great Britain, is the international coordinating investigator. For Germany, Stefan Rutkowski, Hamburg, Germany is the national coordinating investigator.

    HRMB is designed to answer two main questions:

    • Can the outcome in children and adolescents with HRMB be improved over standard therapy (conventional (once a day) radiotherapy (RT)) for those treated with:
      • hyperfractionated-accelerated radiotherapy (HART), or
      • high-dose therapy (HDT) with thiotepa followed by conventional RT?
      • Is the outcome in HR-MB is different for those treated with two different maintenance chemotherapy therapies?

    As secondary objective, questions on tumor biology and various late effects (e.g. quality of survival, neuropsychological follow-up) will be addressed.

    EudraCTNr: 2018-004250-17

  • PNET5

    Patient recruitment has been completed as of 06.04.2022 and no more patients can be included.

    PNET5 is a prospective multicenter phase II/III clinical trial to optimize the therapy for children, adolescents and young adults with non-metastatic standard risk medulloblastoma (PNET 5 MB-SR), WNT medulloblastoma (PNET 5 MB-LR, PNET 5 MB –WNT-HR), or SHH medulloblastoma with TP53 mutation (PNET 5 MB – SHH-TP53 arm). To be included, patients need to be older than 3 or 5 years, depending on histological medulloblastoma subtype.
    Stefan Rutkowski, Hamburg, Germany and François Doz, Paris, France are principal investigators of this trial, the sponsorship has been taken over by the University Medical Center Hamburg-Eppendorf, Hamburg, Germany.
    PNET5 is designed to answer two main questions:

    • Is it safe to reduce the intensity of therapy in patients with low-risk medulloblastoma,as measured by the rate of relapse-free survival?
    • Does carboplatin given simultaneously to the postoperative radiotherapy in patients with standard-risk medulloblastoma increase the relapse-free survival compared to radiotherapy alone?

    As secondary objectives, questions on tumor biology and various late effects (e.g. quality of survival, neuropsychological follow-up) will be addressed.

  • HIT2000 and PNET4

    HIT2000 was a multicentric clinical trail for children, adolescents and young adults with medulloblastoma, ependymoma or CNS-PNET. PNET4 was an international arm of HIT2000 for patients older than 4 with localized medulloblastoma.
    HIT2000 was open from Jan 1st, 2001 to Dez 31st, 2011 in up to eight European countries. More than 150 pediatric oncology centers registered more than 1300 patients in that period into one of the nine treatment strata. Besides the impact of other unifying international activities, HIT2000/PNET4 was a further step into the current fruitful European collaborations in brain tumor research.
    The different treatment strata of HIT2000 are currently in different stages of evaluation. While for some arms, results have been published, others still need to be evaluated within the next years.

  • Neuropsychological co-study

    Within the neuropsychological co-study, patients with medulloblastoma, ependymoma and CNS-PNET receive neuropsychological assessments if they were between 0 and 21 years at diagnosis and were registered to one of the clinical trials or clinical registered organized by the HIT-MED trial office. The assessments include tests for problems with concentration, fine motor skills or memory. The results are combined with the clinical data obtained during the treatment course and analyzed systematically in order to quantify post-treatment neuropsychological outcome of the patients and to identify potential risk factors that have influence on the outcome.

    Additionally, patients and their families receive a detailed report on their test results. This results includes recommendations on how to improve school / professional and everyday reintegration and discusses options on where to find further support, if necessary.
