fibroblast growth factor (fgfs) / fibroblast growth factor receptor (fgfrs) genetic as a second-line therapy for recurrent / progressive gastric cancer with incb054828 and paclitaxel a study to evaluate the safety and efficacy of combination therapy.

Conditions: Fibroblast Growth Factors (FGFs)/Fibroblast Growth Factor Receptors (FGFRs) Genetic Aberration Gastric Cancer, INCB054828, Paclitaxel

Summary: this study was conducted as a second-line treatment of recurrent / progressive gastric cancer patients with fgfs / fgfrs genetic mutations in the ib / ii clinical trial. the maximum maximal tolerated dose (mtd) and 2-phase recommended dose in combination with incb054828 and paclitaxel (recommended phase ii dose, rp2d), and evaluate the safety and clinical efficacy of this combination therapy. this study consists of two steps: phase 1 is a dose escalation study to determine the maximum tolerated dose and 2-phase recommended dose of weekly paclitaxel and incb054828 combination therapy, and phase 2 is the dose escalation study in combination with incb054828 and paclitaxel assess safety and tolerability and identify antitumor effects in stomach cancer with fgfs / fgfrs genetic mutations.

1. phase\> - approximately 3-12 patients will be enrolled. the dose escalation will be three patients registered for each cohort until the first dose-limiting toxicity appears during the four weeks of treatment and observation. 13.5mg, once a day begins to take. the paclitaxel is administered once a week for three consecutive weeks and then for one week, followed by a total of four weeks in one cycle. 2. phase\> phase 2 studies will be extended to a total of 30 patients with a two-phase recommended dose. patients will be treated until the time of disease progression, intolerable toxicity, rejection of the patient, or withdrawal of consent. in its pre-screening phase, its next generation sequencing (ngs) is performed. patients with fgfs / fgfrs genetic abnormalities may be enrolled in this study. if a patient has multiple genetic abnormalities, he or she will first be enrolled in a treatment group that targets a rare genetic abnormality. registered patients will be treated on a continuous basis every four weeks.
