A Phase 1 Open-label Dose Escalation and Dose Expansion Study of CGX1321 in Subjects With Advanced Solid Tumors and Phase 1b Study of CGX1321 in Combination With Pembrolizumab in Subjects With Advanced Gastrointestinal Tumors

This is a multicenter, open-label study conducted in two phases: Phase 1 consisting of a
CGX1321 Single Agent Dose Escalation Phase in solid tumors and Dose Expansion Phase in GI
tumors and Phase 1b consisting of CGX1321 in combination with pembrolizumab in colorectal
tumors. Both phases are to evaluate safety, pharmacokinetics, and clinical activity.

The purpose of the Dose Escalation Phase is to examine the safety and determine the maximum
tolerated dose of CGX1321 when administered to subjects with advanced solid tumors.

The purpose of the Dose Expansion Phase and Phase 1b is to continue to examine the safety and
confirm the final Phase 2 dose of CGX1321 alone in subjects with advanced GI tumors (Dose
Expansion Phase) and evaluate the safety and tolerability of CGX1321 in combination with
pembrolizumab in subjects with colorectal tumors (Phase 1b)

Inclusion Criteria:

- Pathologically-confirmed, locally advanced or metastatic solid tumors that have
relapsed or are refractory to or are not considered medically suitable to receive
standard of care treatment (Dose Escalation Phase)

- Histologically-diagnosed, advanced Gl tumors that have relapsed or are refractory to
or are not considered medically suitable to receive standard of care treatment (Dose
Expansion Phase)

- Histologically-diagnosed advanced colorectal tumors that have relapsed or are
refractory to or are not considered medically suitable to receive standard of care
treatment (Phase 1b)
