7. Study Summary
Lay Summary | As no promising agents are available in treating recurrent/metastatic gastric cancer, development of novel agents, especially biological targeting agents, is essential for improving the survival of gastric cancer. This is a study to determine the maximum tolerated dose (MTD) and the recommended dose schedule of varlitinib in combination with paclitaxel and to further assess the safety and clinical efficacy of this combined treatment in EGFR(Epidermal growth factor receptor)/HER2(Human epidermal growth factor receptor 2) co-expressing advanced or metastatic gastric cancer after first line treatment. |

Allocation | Non-RCT |
Intervention Type | Drug |
Intervention Description | Phase 1b> We will be started with oral varlitinib 300mg, bid, continuous dose. Initially, 3 patients per cohort are planned to be included in this part of the study, until the occurrence of first DLT(dose limited toxicity) within 4 weeks of treatment and observation. If it is well tolerated i.e. no DLT(dose limited toxicity) is observed from initial 3 patients, the RP2D(Recommended phase 2 dose) for varlitinib will be 300mg, bid, continuous schedule. If one DLT(dose limited toxicity) is observed from initial 3 patients, 3 more patients will be added to this cohort. If 1 DLT(dose limited toxicity) is observed from these 6 patients, the RP2D(Recommended phase 2 dose) for varlitinib will be 300mg, bid, continuous dosing schedule. If 2 or more patients (in 6 patients cohort) experience DLT(dose limited toxicity), the RP2D(Recommended phase 2 dose) for varlitinib will be 300mg, bid, intermittent dosing (day 3-6/week schedule). Paclitaxel will be administered to each patient as an intravenous infusion of 80mg/m2 every weekly (i.e. on days 1,8 and 15) for 4 weeks (i.e. 3 weeks of study treatment administration and 1 week of rest period). Phase 2> We will be started with oral Varlitinib will be administered based on RP2D and Paclitaxel will be administered as intravenous infusion of 80mg/m2 every weekly for 3 weeks with 1 week of rest period until the time of disease progression, development of intolerable toxicities, patient’s refusal or consent withdrawal or death. |
