Cantargia (Cantargia AB; Nasdaq Stockholm: CANTA) today reported updated results from the phase 1b study in 15 advanced triple negative breast cancer (aTNBC) patients treated with nadunolimab combined with platinum-based chemotherapy. The results confirm previous positive findings on safety, and promising antitumor activity. The clinical results along with new biomarker studies will be presented in a poster session at the upcoming San Antonio Breast Cancer Symposium (SABCS), 2024.
“Besides the strong clinical results already reported in pancreatic and lung cancers, we are excited to present these data in triple negative breast cancer. The presentation includes value-adding information around nadunolimab and its potential effects on the immune system’s ability to counteract cancer progression,” said Göran Forsberg, CEO of Cantargia.
The TRIFOUR phase 1b part evaluated nadunolimab at 1 mg/kg (n=3) and 2.5 mg/kg (n=12) combined with gemcitabine and carboplatin (GC) in 15 previously treated aTNBC patients. Initial results were presented in 2023, and the updated results confirm an acceptable safety profile with a promising efficacy of 60% response rate, 6.2 months progression-free survival (PFS), and 12.8 months overall survival (OS).
Analysis of patient samples was performed to identify features connected to nadunolimab/GC treatment. A significant reduction in the neutrophil to lymphocyte ratio (NLR) and C-reactive protein (CRP) was detected, both related to the nadunolimab mode of action. Additionally, a significant decrease in IL-8 levels was associated with a trend towards longer OS. These findings suggest that nadunolimab exerts beneficial effects on immune cells involved in tumor-promoting inflammation.
Using a larger, separate set of pre-treatment tumor biopsies and blood samples, a characterization of IL1RAP expression was also performed. This analysis showed IL1RAP expression on tumor, stromal and tumor-infiltrating immune cells. Detailed analysis of circulating cells showed IL1RAP expression on myeloid cells, including myeloid-derived suppressor cells highlighting the relevance of IL1RAP as a promising target in aTNBC.
The trial is currently enrolling patients for the randomized phase 2 part at the 2.5 mg/kg dose of nadunolimab with GC vs. only GC. Initial results for this part of the study are expected late H1 2025.
The study is done in collaboration with GEICAM (Spanish Breast Cancer Research Group) and will be presented in a poster session at the 47th annual San Antonio Breast Cancer symposium (SABCS), Dec 10-13, 2024.
