About

The GrantPax study is a multicenter phase 4 geriatric assessment directed trial to evaluate gemcitabine +/- nab-paclitaxel in elderly pancreatic cancer patients. The primary objective is that CGA-stratified patients do not decline in their CGA performance in response to chemotherapy measured as a loss of five points or less in the Barthel's ADL, (ADL1 vs. ADL2 during core CGA assessment).

Full description

The hypothesis of the proposed study is that individualized assessment directed treatment algorithms identifies elderly patients, who benefit from combined nab-paclitaxel/gemcitabine therapy. The project uses a CGA, which includes various tests and scoring systems, to stratify patients as "GO-GO", "SLOW-GO" or "FRAIL" patients. Depending on test results patients receive chemotherapy (GO-GO group: nab-paclitaxel/gemcitabine; SLOW-GO group: gemcitabine monotherapy) or best supportive care (FRAIL group). After the first cycle of chemotherapy (4 weeks) a subsequent CGA and a safety assessment will be performed to assign patients to their definite treatment arm. The primary objective is that CGA-stratified patients do not decline in their CGA performance in response to chemotherapy measured as a loss of five points or less in the Barthel's ADL (ADL1 vs. ADL2 during core CGA assessment).
