The study will determine the recommended Phase 2 dose (RP2D) of ABBV-151 administered as monotherapy and in combination with budigalimab (ABBV-181) as well as to assess the safety, pharmacokinetics (PK), and preliminary efficacy of ABBV-151 alone and in combination with budigalimab. The study will consist of 2 phases: dose escalation and dose expansion.

Inclusion Criteria

For Dose Escalation only: Participants with an advanced solid tumor who are considered refractory to or intolerant of all existing therapy(ies) known to provide a clinical benefit for their condition. Additionally, participants who have been offered standard therapies and refused, or who are considered ineligible for standard therapies, may be eligible for this study on a case-by-case basis, after discussion with and agreement from the sponsor. Participants with triple-negative breast cancer (TNBC), pancreatic adenocarcinoma, urothelial cancer, Hepatocellular carcinoma (HCC), or Head and neck squamous cell carcinoma (HNSCC) who are being considered for the dose escalation cohorts must also meet the histology specific eligibility criteria described below for dose expansion
For Dose Expansion only participants must meet criteria specific to the type of
TNBC - Female or male participants with confirmed breast adenocarcinoma that is ER-negative, PR-negative, and HER2-negative, (as defined per American Society of Clinical Oncology [ASCO]/College of American Pathology [CAP] guidelines), who must have disease progression during or after at least 1 systemic therapy that included a taxane in the metastatic or recurrent setting
Pancreatic adenocarcinoma and have disease progression during or after 1 systemic therapy (gemcitabine monotherapy or in combination with other agents, FOLFIRINOX [or another regimen including both 5-fluorouracil and oxaliplatin], capecitabine monotherapy or in combination with other agents) administered in the adjuvant, locally advanced, or metastatic setting. If the therapy was used in an adjuvant setting, disease progression must have occurred within 6 months of completing adjuvant therapy
Urothelial cancer of the bladder and urinary tract and must have progressed following treatment with a platinum-based regimen (administered in any line of therapy) and a programmed death 1/programmed death ligand 1 (PD1/PDL1) antagonist administered in the recurrent or metastatic setting (progression following a PD1/PDL1 antagonist is defined as unequivocal progression on or within 3 months of the last dose of anti-PD1 or anti-PDL1 therapy)
HCC and must have disease progression during or after 1 prior line of systemic therapy
HNSCC (arising from the oral cavity, oropharynx, hypopharynx, or larynx) and must have progressed following treatment with platinum-based regimen (administered in any line of therapy) and a PD1/PDL1 antagonist administered in the recurrent or metastatic setting (progression following a PD1/PDL1 antagonist is defined as unequivocal progression on or within 3 months of the last dose of anti-PD1 or anti-PDL1 therapy)
CRC participants with microsatellite stable or mismatch repair proficient colorectal adenocarcinoma (as determined by PCR/NGS or IHC, respectively) who have received 1-2 prior chemotherapy regimens and who have refused or are ineligible for other approved therapies
Participant has an Eastern Cooperative Oncology Group (ECOG) Performance Status of 0
to 1
Participant has adequate bone marrow, renal, hepatic, and coagulation function
Must have a viral status consistent with the requirements described in the protocol specific to type of cancer and stage of study (Dose Escalation or Dose Expansion)

Exclusion Criteria

For Dose Expansion only: Participants (except for participants with urothelial cancer or HNSCC) who have had prior exposure to immunotherapies as listed in the protocol
Has received anticancer therapy including chemotherapy, immunotherapy, radiation therapy, biologic, herbal therapy, or any investigational therapy within a period of 5 half-lives or 28 days (whichever is shorter), prior to the first dose of the study drug
Participant has unresolved AEs > Grade 1 from prior anticancer therapy except for alopecia
Has a history of primary immunodeficiency, bone marrow transplantation, solid organ transplantation, or previous clinical diagnosis of tuberculosis
Has a known uncontrolled metastases to the central nervous system (with certain exceptions)
Current or prior use of immunosuppressive medication within 14 days prior to the first dose of the study drug
Has clinically significant uncontrolled condition(s)
History of inflammatory bowel disease, interstitial lung disease or pneumonitis, myocarditis, Stevens-Johnson syndrome, toxic epidermal necrolysis or drug reaction with eosinophilia and systemic symptoms (DRESS)
Live vaccine administration <= 28 days prior to the first dose of study drug
