Description
CC-115 is a dual inhibitor of DNA-dependent protein kinase (DNA-PK) and mammalian target of rapamycin (mTOR), with potential antineoplastic activity. CC-115 binds to and inhibits the activity of DNA-PK and both raptor-mTOR (TOR complex 1 or TORC1) and rictor-mTOR (TOR complex 2 or TORC2), which may lead to a reduction in cellular proliferation of cancer cells expressing DNA-PK and TOR. DNA-PK, a serine/threonine kinase and a member of the PI3K-related kinase subfamily of protein kinases, is activated upon DNA damage and plays a key role in repairing double-stranded DNA breaks via the DNA nonhomologous end joining (NHEJ) pathway.

In Vitro Activity
To evaluate the impact of CC-115 inhibition of mTOR kinase and DNA-PK, CC-115 was tested in vitro across a panel of 123 cancer cell lines composed of 40 lymphoma and leukemia, 22 breast cancer, 11 hepatocellular carcinoma, 11 head and neck cancer, and 39 lung cancer cell lines. CC-115 has potent growth inhibitory activity against the majority of the cancer cell lines with GI50 values ranging from 0.015 μM to 1.77 μM (Figure2A2A and Supplementary Table 2). While selective inhibitors of mTOR kinase have been reported to primarily result in cell cycle arrest without significant induction of apoptosis in solid tumor lines, in a subset of both hematological and solid tumor cell lines, CC-115 induced strong apoptosis. CC-115 also inhibited NHEJ activity in a concentrationdependent manner. Partial inhibition was observed with 0.5 μM CC-115 treatment (lane 3) and 5 μM CC-115 achieved complete inhibition (lane 4). Therefore, CC-115 prevents NHEJ by blocking autophosphorylation of DNA-PKcs and dissociation of DNA-PKcs and the ligase IV/XLF/XRCC4 complex from the dsDNA end. This study suggests the use of ATM deficiency as a patient selection strategy for CC-115 as a single agent.

In Vivo Activity
The in vivo activity of CC-115 was tested. As described, 786-O cells were s.c. injected into the flanks of the nude mice. Xenografts were established within three weeks (tumor volumes close to 100 mm3, labeled as "Day-0"). The tumor-bearing mice were randomly assigned into three groups, receiving CC-115 or vehicle control. Results demonstrated that oral administration of CC-115, at 2 mg/kg or 5 mg/kg, significantly inhibited subcutaneous 786-O xenograft growth in nude mice (Figure 5A). The estimated daily 786-O tumor growth, calculated by (tumor volume at Day-30 subtracting tumor volume at Day-30)/30, was dramatically inhibited in CC-115treated mice (Figure 5B). Tumors of all three groups were isolated at Day-30 and weighted (Figure 5C). Tumors with CC-115 treatment were much lighter than the vehicle-treated tumors (Figure 5C). The mouse body weights were not significantly different between the three groups (Figure 5D). Collectively, oral administration of CC-115 inhibited subcutaneous 786-O xenograft growth in mice.
