TeloVac
Study hypothesis
In patients with locally advanced or metastatic pancreatic adenocarcinoma, does the addition of telomerase vaccine GV1001, when given concurrently or sequentially, to combination gemcitabine and capecitabine, improve survival over treatment with combination gemcitabine and capecitabine alone.
Ethics approval
Ethical review pending
Study design

Intervention
Arm 1 - Gemcitabine and capecitabine therapy: Gemcitabine will be administered on day one, eight and 15 followed by seven days rest. Per oral capecitabine will be administered morning and evening for 21 days followed by seven days rest. Gemcitabine and capecitabine therapy cycles will be repeated every four weeks until withdrawal from trial treatment.
Arm 2 - Gemcitabine and capecitabine then sequential GV1001 therapy: Patients will receive two cycles of combination gemcitabine and capecitabine before commencing GV1001 alone. Each of the two cycles of combination gemcitabine and capecitabine consists of:
Gemcitabine will be administered on day one, eight and 15 followed by seven days rest. Per oral Capecitabine will be administered morning and evening for 21 days followed by seven days rest. Following completion of gemcitabine and capecitabine therapy, GV1001 will be administered intradermally on Monday, Wednesday and Friday during week eight and once weekly during weeks nine, ten, 11, 13 and 17. Thereafter, vaccinations will follow a once monthly schedule until withdrawal from trial treatment.
Arm 3 - Concurrent Gemcitabine, Capecitabine and GV1001 therapy: Gemcitabine will be administered on day one, eight and 15 followed by seven days rest. Per oral Capecitabine will be administered morning and evening for 21 days followed by seven days rest. Gemcitabine and Capecitabine therapy cycles will be repeated every four weeks until withdrawal from trial treatment. GV1001 will be administered intradermally on Monday, Wednesday and Friday during week one followed by a once weekly schedule for weeks two, three, four, six and ten. Thereafter, GV1001 will be administered once monthly until withdrawal from trial treatment.
