This is an open-label, Phase I, dose-escalation study to determine the maximum tolerated dose (MTD) and/or recommended phase two dose (RPTD), and evaluate the safety, efficacy, and pharmacokinetic (PK) profile of ABBV-621 for participants with previously-treated solid tumors or hematologic malignancies.
Only chemotherapy combination (ABBV-621 + FOLFIRI) enrolling participants with RAS-mutant CRC who have received one prior line of therapy is open for enrollment.

Participants in the Dose Optimization solid tumor cohorts must have either colorectal cancer with documented KRAS mutations (as determined by local testing), or pancreatic cancer (irrespective of mutational status). Participants in the chemotherapy combination cohorts must have metastatic or advanced unresectable colorectal cancer with documented RAS mutations (as determined by local testing).

-
Must agree to provide the following samples for biomarker analysis:
- All participants: archived tumor tissue (if available).
- Participants in Dose Optimization (excluding AML): pre- and on-treatment fresh tissue biopsies. (Note: fresh tissue biopsies will be optional for participants with solid tumor or NHL in Dose Escalation and will be collected only if consent is provided)
- All participants with AML: pre- and on-treatment bone marrow aspirates (BMA)
- Participants in chemotherapy combination cohorts: participants must provide a fresh biopsy if an archival biopsy is not available
