Figure 4. Ibrutinib has a significant therapeutic impact as monotherapy and in combination with standard of care. Two independent experiments were conducted to determine the survival effect of ibrutinib.
A, p53ER/ER;LSLKRasG12D;Pdx1-cre mice were treated with ibrutinib (n = 14) or vehicle control (n = 13) starting from 8 weeks of age. Ibrutinib alone confers survival advantage to the treated animals (P = 0.030, log-rank test). B, p53ER/ER;LSLKRasG12D;Pdx1-cre mice were treated with gemcitabine (n = 8) or with a combination of gemcitabine and ibrutinib (n = 9), starting from 8 weeks of age. The addition of ibrutinib to standard of care improves animal survival (P = 0.025, log-rank test).
