New cancer drug ABBV-155 enters first human tests
NCT ID NCT03595059
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase study tested a new drug called ABBV-155, given alone or with standard chemotherapy (paclitaxel or docetaxel), in 168 adults with advanced solid tumors that had come back or stopped responding to treatment. The main goal was to find a safe dose and check for early signs of tumor shrinkage. The study included people with small cell lung cancer, non-small cell lung cancer, and breast cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ABBV-155 (a drug given intravenously, alone or with paclitaxel or docetaxel)
- What this could lead to
- If it works, this could point toward a new treatment option for certain advanced solid tumors like lung or breast cancer.
- What could go wrong
- This is a very early Phase 1 trial, so the main goals are safety and dosing, not yet proving effectiveness. Many drugs fail at this stage, and side effects are unknown.

Inclusion Criteria: * Has a histologic or cytologic diagnosis of a malignant solid tumor. * Participants enrolled in Part 2a (monotherapy, dose expansion) must have small cell lung cancer (SCLC) diagnosis; participants enrolled to Part 2b (combination therapy, dose expansion) must have either NSCLC or HR-positive/HER2-negative breast cancer. * Measurable disease defined by Response Evaluation Criteria in Solid Tumors (RECIST) criteria. * An Eastern Cooperative Oncology Group (ECOG) performance status less than or equal to 2. * Failure of at least 1 prior systemic chemotherapy including all available standard therapies for participants in the dose-escalation phase (Parts 1a and 1b) including the safety lead-in phase (Japan only). * All participants with breast cancer for subjects in the dose-expansion phase (Part 2b only) must have the following: * Locally advanced or metastatic HR-positive/HER2-negative breast cancer after failing cyclin-dependent kinase (CDK)4/6 inhibitor-based therapy. * HR-positivity and HER-2-negativity should be confirmed based on American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) criteria. * All participants with non-small cell lung cancer (NSCLC) for participants in the dose-expansion phase (Part 2b only) must have R/R NSCLC after at least 1 line of therapy. Participants with activating mutations in EGFR, ALK/ROS1, BRAF genes, or with positive expression of PD-L1 must have been treated with the appropriate targeted therapies. * All participants with SCLC in the dose-expansion phase (Part 2a only) must have R/R SCLC from at least 1 line of therapy which includes a platinum-based therapy with or without an anti-PD-1/PD-L1 therapy. * All participants with either breast cancer or NSCLC must have the following if exposed to prior taxane-based therapy: * No history of taxane allergy (Part 1b and Part 2b only). * Disease that has relapsed or progressed at least 2 months after most recent exposure to any taxane-based therapy. * Available tumor tissue suitable for immunohistochemistry testing. * Adequate kidney, liver, and hematologic laboratory values as described in the protocol. Exclusion Criteria: * Untreated brain or meningeal metastases (participants with a history of metastases may be eligible based on details described in the protocol). * Grade 2 or higher peripheral neuropathy (only applies to participants who would receive taxane therapy). * Unresolved Grade 2 or higher toxicities related to previous anticancer therapy except alopecia. * Known active infection of hepatitis B, hepatitis C, or human immunodeficiency virus with exceptions as described in the protocol. * Recent history (within 6 months) of congestive heart failure (defined in the protocol), ischemic cardiovascular event, cardiac arrhythmia requiring pharmacological or surgical intervention, pericardial effusion, or pericarditis. * Any history of hypersensitivity to any ingredients of ABBV-155 will be excluded. For combination therapy only (Parts 1b and 2b), no history of serious allergic reaction to any taxane or any ingredients used in taxane formulation (e.g., cremaphor).
