<p>Abstract</p> <p>Background</p> <p>Although Temozolomide is effective against glioblastoma, the prognosis remains dismal and new regimens with synergistic activity are sought for.</p> <p>Methods</p> <p>In this phase-I/II trial, pegylated liposomal doxorubicin (Caelyx™, PEG-Dox) and prolonged administration of Temozolomide in addition to radiotherapy was investigated in 63 patients with newly diagnosed glioblastoma. In phase-I, PEG-Dox was administered in a 3-by-3 dose-escalation regimen. In phase-II, 20 mg/m²PEG-Dox was given once prior to radiotherapy and on days 1 and 15 of each 28-day cycle starting 4 weeks after radiotherapy. Temozolomide was given in a dose of 75 mg/m²daily during radiotherapy (60 Gy) and 150-200 mg/m²on days 1-5 of each 28-day cycle for 12 cycles or until disease progression.</p> <p>Results</p> <p>The toxicity of the combination of PEG-Dox, prolonged administration of Temozolomide, and radiotherapy was tolerable. The progression free survival after 12 months (PFS-12) was 30.2%, the median overall survival was 17.6 months in all patients including the ones from Phase-I. None of the endpoints differed significantly from the EORTC26981/NCIC-CE.3 data in a post-hoc statistical comparison.</p> <p>Conclusion</p> <p>Together, the investigated combination is tolerable and feasible. Neither the addition of PEG-Dox nor the prolonged administration of Temozolomide resulted in a meaningful improvement of the patient's outcome as compared to the EORTC26981/NCIC-CE.3 data</p> <p>Trial registration</p> <p>clinicaltrials.gov NCT00944801.</p>
