New cancer drug combo targets Hard-to-Treat tumors
NCT ID NCT05155332
First seen Jun 27, 2026 · Last updated Aug 20, 2026 · Updated 5 times
Summary
This early-phase study tests a new drug, BI 1831169, given alone or with an immunotherapy (anti-PD-1 antibody) in adults with advanced solid tumors that cannot be removed by surgery or have spread. The main goals are to find the highest safe dose and see if the treatment shrinks tumors. Participants receive the drug every 3 weeks for up to 3 months (alone) or up to 1 year (with immunotherapy). The trial is currently on hold.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- BI 1831169 (injected into tumor or infused into vein) and an anti-PD-1 antibody (checkpoint inhibitor, infused into vein)
- What this could lead to
- If it works, this could point toward a new treatment option for advanced solid tumors that are hard to treat.
- What could go wrong
- This is a very early (Phase 1) and small study, so the treatment may not work or may cause side effects. The trial is currently suspended, which adds uncertainty.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Histologically or cytologically confirmed diagnosis of advanced, unresectable and/or metastatic or relapsed/refractory solid tumors * At least one or two accessible lesions, one with a minimum lesion diameter for injection of BI 1831169 (where applicable), and one which is amenable to biopsy (where applicable). Lesions must either be easily accessible or, if not easily accessible, patient must be willing to undergo repeated procedures (e.g., image guided procedures) for both biopsies and injections of BI 1831169 * Has failed conventional treatment or for whom no therapy of proven efficacy exists, who is not eligible for established treatment options. Patient must have exhausted available treatment options known to prolong survival for their disease. This criterion does not apply to the specific indications in Part 2. Further inclusion criteria apply. Exclusion Criteria: * Previous treatment with Vesicular stomatitis virus (VSV)-based agents * Concomitant medication or condition considered a high risk for complications from injection or biopsy as per the Investigator's judgement * Presence of brain metastases * Presence of Human Immunodeficiency Virus (HIV) meeting certain criteria, active autoimmune disease or chronic active infection (Hepatitis C or B virus (HCV/HBV)) * Chronic steroid use, regardless of daily dose Further exclusion criteria apply.
