Summary

The treatment of germ cell tumours is considered to be one of the major successes in the area of cytotoxic chemotherapy. Even in patients who relapse after first line therapy, a durable remission rate of between 25% and 60% has been seen using further chemotherapy. In 1999, researchers at St Bartholomew's Hospital developed the GAMEC protocol (combination chemotherapy with filgrastim, actinomycin D, methotrexate, etoposide, cisplatin). Results from this study showed that 50% of patients with relapsed testicular cancer could be cured using this treatment. When we reviewed the individual patients it was clear that older patients (\>35yrs) or patients with a raised Lactate Dehydrogenase (a blood test that monitors cancer activity), did not do as well. In addition, patients whose original tumour started in their chest (mediastinal germ cell tumour) have tended to do badly if they relapse. We have been developing a study for patients who fulfil at least one of these criteria. The GAMIO study (filgrastim, actinomycin D, methotrexate, irinotecan, oxaliplatin) has recently closed due to problems with high levels of toxicity from the irinotecan. GAMMA is a new study that will use paclitaxel instead of irinotecan and oxaliplatin instead of cisplatin. We expect that this treatment with oxaliplatin will be less damaging to the kidneys than cisplatin. Both oxaliplatin and paclitaxel and oxaliplatin and irinotecan have similar activity in relapsed patients in the phase II setting. We hope to improve on our previous results with this substitution and see if this will lead to an improvement in the cure rate of relapsed germ cell tumours with poor prognosis and reduce the side effects compared to our standard treatment. In addition, we do not expect any hearing damage and the treatment requires a shorter hospital stay.

Interventions

DRUG

Combination Chemotherapy

4 cycles of: Day 1 Actinomycin D 1mg/m2, Paclitaxel 80mg/m2, Methotrexate Day 4 Oxaliplatin 100mg/m2 Pegfilgrastim 6mg Day 8\* Paclitaxel 80mg/m2 Day 15 Paclitaxel 80mg/m2 \*Day 8 will be omitted for the first three patients treated in this study and will be given at the end of treatment in a fifth cycle where Paclitaxel 80mg/m2 will be administered on Days 1, 8, 15 and 22. Before adding the extra Paclitaxel 80mg/m2 dose on day 8 the safety data for these patients will be reviewed by a DMC. NB This 5th cycle for patients 1-3 has been included to ensure that the four 'missed doses of paclitaxel are not omitted from the patients treatment regimen. Cycles 1-4 are 21 days cycles; Cycle 5 (for the first three patients only) is a 28 day cycle.
