Set the standard for TLS detection
Detect Tertiary Lymphoid Structures across tumor types from digitized H&E slides
Gain insights into a tumor’s interaction with the immune system
A major player in antitumor immune response, the presence of TLS has been associated with improved survival in several tumor types.1
During drug development and clinical trials TLS can serve as a predictive biomarker for response to certain immunotherapies.
Presence of TLS potentially indicates an enhanced immune response making it a possible target for improved response to immunotherapy.2
TLS could guide the development of therapies that target both the tumor cells and the local immune environment.
TLS can support clinical trial optimization, to help better select trial participants to improve success rates across trial phases.

Benefits of TLS detection
As a novel biomarker, TLS presence helps stratify the overall survival risk of untreated cancer patients and helps identify those who may benefit from efficient immunotherapy treatment.
Waiv’s simple and standardized approach could support the adoption of this biomarker as an independent predictor of response to immune checkpoint inhibitors (ICI).
With a sensitivity of 97%, TLS Detect supports the screening for TLS presence across tumors within a research setting.
Determine the status of TLS
Tissue sample is taken and prepared as a H&E slide.
The slide is then digitized.
TLS Detect extracts and analyzes features from the digitized slide.
A PDF report is delivered including a dynamic heat map.
TLS
Presence of TLS, with analysis score provided.
No TLS
No presence of TLS, with analysis score provided.
“As a research tool, TLS Detect has the potential to pre-screen for TLS positive tumor samples, paving the way for optimization of research workflows in multiple tumor indications.”
**97% sensitivity was achieved through validation on an external dataset (n=157 patients)
