For drug dosage and route of administration, we followed reported methods [12 (link)]. In brief, cyclophosphamide (Cy) (Tocris Bioscience) was used at a final concentration of 100 mg/Kg and administrated intraperitoneally (i.p.) twice, each dose one week apart. When LCL161 (Chemietek) was used, 50 mg/Kg LCL161 was administrated via the oral gavage (o.g.) route. The checkpoint inhibitor α-PD-1 (BioXCell) was administrated intraperitoneally (i.p.) at a final concentration of 10 mg/Kg. One week after cancer implantation, both LCL161 and α-PD-1 were administrated on days 1, 4, 8, 11 as described in Figure 4A.
