Brief Summary

Cancer is a condition where cells in a specific part of body grow and reproduce uncontrollably. The purpose of this study is to assess safety, tolerability, pharmacokinetics and preliminary efficacy of ABBV-303 as a monotherapy and in combination with budigalimab, (ABBV-181).

ABBV-303 is an investigational drug being developed for the treatment of solid tumors. There are multiple treatment arms in this study. Participants will either receive ABBV-303 as a single agent or in combination with budigalimab (another investigational drug) at different doses. Approximately 181 adult participants will be enrolled in the study across sites worldwide.

In Part A, ABBV-303 will be intravenously (IV) infused in escalating doses as a monotherapy in participants with relapsed (R)/refractory (R) solid tumors, R/R non-small cell lung cancer (NSCLC), R/R renal cell carcinoma (RCC), R/R head and neck squamous cell carcinoma (HNSCC), or R/R tissue agnostic participants with mesenchymal epithelial transition. In Part B, ABBV-303 in combination with budigalimab will be IV infused in participants with R/R solid tumors or NSCLC. The estimated duration of the study is up to 3 years.

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic and may require frequent medical assessments, blood tests, and scans.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Adverse Events (AE)Up to 3 Years

An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment.

Secondary Outcome Measures
NameTimeMethod
ORR per Immune-Mediated Response Evaluation Criteria in Solid Tumors (iRECIST)Up to 3 Years

ORR defined as percentage of participants with confirmed best overall response of Confirmed complete response (CR) and partial response (PR) per investigator review according to iRECIST version 1.1.

Objective Response Rate (ORR) per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1Up to 3 Years

ORR defined as percentage of participants with confirmed best overall response of Confirmed complete response (CR) and partial response (PR) per investigator review according to RECIST version 1.1.

Duration of Response (DOR) for Participants with Confirmed CR/PR per RECIST v1.1Up to 3 Years

DOR is defined for participants achieving a confirmed CR+PR as the time from the initial response of CR+PR per investigator review according to RECIST 1.1 criteria to disease progression or death of any cause, whichever occurs earlier.

Progression-free survival (PFS)Up to 3 Years

PFS is defined as time from first study treatment to a documented disease progression according to RECIST version 1.1, as determined by the investigator, or death due to any cause, whichever occurs earlier.

Overall survival (OS)Up to 3 Years

OS is defined as time from first study treatment to death due to any cause.
