Can a cocktail of immune boosters shrink Hard-to-Treat tumors?
NCT ID NCT03893955
First seen Sep 02, 2026 · Last updated Sep 03, 2026 · Updated 1 time
Summary
This phase 1 trial tests whether combining several investigational immunotherapy drugs, with or without chemotherapy, can safely shrink advanced solid tumors. The study enrolls adults with cancers like non-small-cell lung cancer or triple-negative breast cancer that have progressed on standard treatments. Researchers first find a safe dose, then expand to measure how well the combinations work.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A combination of investigational immunotherapy drugs (ABBV-927, ABBV-368, budigalimab) with or without chemotherapy
- What this could lead to
- If successful, this could point toward new combination treatments that shrink or control advanced solid tumors, including lung and triple-negative breast cancers.
- What could go wrong
- This is an early phase 1 trial, so the main goals are safety and finding the right dose. The combinations may not work, and side effects could be significant.

Inclusion Criteria: * Adequate liver, kidney and hematology function as demonstrated by laboratory values detailed in the study protocol. * An Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. Dose-Escalation: * Arm A: Participants with an advanced solid tumor who have progressed on standard therapies known to provide clinical benefit and/or participants who have refused or are intolerant of such therapy. * Arm B (non-small-cell-lung-cancer \[NSCLC\]): Participants with histologically or cytologically confirmed NSCLC who previously progressed during or after an anti-programmed cell death (PD)-1 or PD ligand 1 (PD-L1) therapy and a platinum-based regimen in the recurrent or metastatic setting. Dose-Expansion: * Arm 1, 2, and 3 (triple-negative breast cancer \[TNBC\]): Participants with histologically or cytologically confirmed breast adenocarcinoma that is estrogen receptor/progesterone receptor/human epidermal growth factor receptor (HER)2-negative who must have disease progression during or after at least 1 systemic therapy that included a taxane in the metastatic or recurrent setting and who are treatment-naïve to immunotherapy. * Arm 4 (TNBC): Participants with histologically or cytologically confirmed TNBC who have received no previous anti-cancer therapy for TNBC, and who are PD-L1 negative on tumor tissue by immunohistochemistry (IHC) assay. * Arm 5 (NSCLC): Participants with histologically or cytologically confirmed NSCLC who previously progressed either during or after an anti-PD-1 or PD-L1 therapy and a platinum-based regimen in the recurrent or metastatic setting. Exclusion Criteria: * Has history of inflammatory bowel disease or pneumonitis. * Has uncontrolled metastases to the central nervous system. * Has a concurrent malignancy that is clinically significant, treatment is required, or the participant is not clinically stable. * Has had a major surgery ≤ 28 days prior to the first dose of study drug or the surgical wound is not fully healed. * Has previously treated with an anti-PD- or PD-L1-targeting agent and had during the course of their therapy: * any immune-mediated toxicity of Grade 3 or worse severity * treatment of the toxicity with systemic corticosteroids * any hypersensitivity to the PD-1 or PD-L1-targeting agent * any treatment-related toxicity resulting in discontinuation of the PD-1 or PD-L1 targeting agent
