Transcript of "Brain Tumor CSG 2007-8 Annual Report"

  1. 1. Annual report 2007-8 NCRI Brain Tumour Clinical Studies Group Introduction The Brain Tumour Clinical Studies Group (BTSG) has continued to work towards increasing the range of clinical studies available for brain tumour patients in the UK. In the past year we have also begun to address some of the long term issues underlying poor recruitment in rare tumour types, identified new funding sources to help support brain tumour studies and forged closer links with the paediatric and teenage and young adult groups. The newly set up expertise based subgroups of the BTSG have all been very active in the last year and several new study ideas are being developed through them. Membership and structure Since the progress review in February 2007, five expertise based subgroups have been set up to address research issues in imaging, translational research, palliative care, technology development and use of new agents in brain tumours. These have been very active in the last year and several new study ideas have been brought forward. Most notably the Novel Agents Subgroup has been involved in the design of 2 new phase I studies in GBM and CNS lymphoma respectively and a phase II study using a novel repair inhibitor with radiation in poor prognosis GBM. The Palliative Care Subgroup has also begun a pilot study addressing the needs of carers of brain tumour patients. The Imaging Subgroup has been very active in exploring means of co-ordinating the approach to use of novel imaging in clinical studies and are preparing a major review of this subject. The Surgical Technology Subgroup is focusing on designing a study to assess the utility of convection enhanced delivery of cytotoxic agents. Portfolio and accrual There are 3 trials currently open in the Group’s portfolio; all are in set up (see Table I below). 2 further trials are open in collaboration with the Radiotherapy and Lung CSG’s, OSCAR and TACTIC respectively. New trials under discussion include a tumour genetics study and several phase II studies testing the effect of novel agents (see below). In the past year the group has successfully completed recruitment to the BR12 trial, which compared the efficacy of Temozolomide against PCV (Procarbazine, CCNU, Vincristine) chemotherapy in chemonaïve patients with recurrent malignant glioma. The translational study linked to the BR12 trial is ongoing and preliminary data have been presented. The first clinical data will be available later in 2008. The Group has also collaborated with the EORTC on a randomised trial examining the role of whole brain radiotherapy after resection or radiosurgery for patients with 1-3 brain metastases. Although recruitment began slowly, increased participation from new centres enabled more rapid recruitment during 2006 and 2007 and the trial was closed in October 2007. A further phase III EORTC study addressing the effect of dose dense temozolomide compared to standard dose temozolomide in newly diagnosed glioblastoma multiforme patients is open in selected centres and is recruiting extremely rapidly, with several UK centres contributing large patient numbers. The Group has joined the EORTC in the development and implementation of a low-grade glioma trial, which compares Temozolomide versus radiotherapy in patients with progressive grade II astrocytomas, - 1 -
  2. 2. Annual report 2007-8 oligodendrogliomas and mixed tumours (EORTC 22033 – 26033), which will open shortly. The major trial in set up is the CATNON (BR14/TATA trial), to examine the role of chemotherapy in patients with grade III astrocytoma (non1p,19q deleted anaplastic glioma). This study will be a major collaborative study between MRC/EORTC and RTOG with a substantial translational component.

A successful one-day meeting was held in December 2007 including a series of talks and discussion to begin to plan a future joint agenda. A further more focussed meeting is planned for 2008 and an opinion document will be published on behalf of those contributing to the first meeting. Collaborations The Group is collaborating in two national brain metastases trials. The OSCAR trial, developed with the Radiotherapy CSG, is assessing the role of radiotherapy in poor prognosis patients with multiple brain metastases from non-small cell lung cancer and will randomise patients between best supportive care and whole brain irradiation. The TACTIC trial, developed in collaboration with the Lung CSG, is assessing the value of Erlotinib (Tarceva) in addition to whole brain radiotherapy using a randomised phase II trial design in patients with inoperable brain metastases from non-small cell lung cancer. Both trials are now open. Further studies for patients with brain metastases from HER2+ breast cancer and melanoma are under discussion with the relevant NCRI Clinical Study Groups. Other activities The Group has been aware of the problems inherent in clinical research in rare tumour types in accessing local resources to support study entry including data management, research nurse and research administration support. Following discussions at CSG meetings an initiative has been agreed with CRUK and The Samantha Dixon Brain Tumour Trust (SDBTT) to make targeted funding available for clinical research in to brain tumours through the Comprehensive Biomedical Centres. SDBTT have also funded a project officer post for the group and we hope to appoint to the post at UCL shortly. The group has been made aware of problems specific to the UK that make participation in European studies challenging, including long lag time between MREC agreement and local set up and variability in local sponsorship agreements. We hope to address these in collaboration with the NCRI EORTC Liaison Officer. 3-year strategy The BTCSG’s three year strategy is to: • Increase proportion of brain tumour patients in UK that are included in high quality clinical studies. • Continue to work closely with the international research community to involve UK patients in available studies - 4 -
