Phase II trial of AZD5363 plus paclitaxel / AZD2014 plus paclitaxel in biomarker negative
(PIK3CA/MEK/RAS/TP53/MET) advanced gastric adenocarcinoma patients as second-line
chemotherapy.
Each arm is composed of 25 patients.
AZD5363 400mg bid 4 days on/ 3 days off of a 7 day cycle for each week that paclitaxel is
given + paclitaxel 80mg/m2 given days 1, 8 and 15 of a 28 day cycle. AZD5363 and paclitaxel
will be received for 3 consecutive weeks, followed by one week off-therapy in 4-week
cycles.If paclitaxel therapy is stopped then AZD5363 can be given on a 4on/3off continuous
schedule.
AZD2014 50mg BD 3 days on 4 days off of a 7 day cycle + paclitaxel 80mg/m2 given days 1, 8
and 15 of a 28 day cycle.
Tumour evaluation using Response Evaluation Criteria in Solid Tumors 1.1 will be conducted at
screening (within 28 days prior to first dose) and every 8 weeks relative to the date of
first dose, up to week 40, then every 16 weeks until objective disease progression (within a
window of +/- 7 days of the scheduled date).
Study treatment will be continued until objective disease progression.
The purpose of this study is to investigate the safety and efficacy of AZD5363 plus
paclitaxel in biomarker negative (PIK3CA/MEK/RAS/TP53/MET) advanced gastric adenocarcinoma
patients as second-line chemotherapy.
