Tertiary lymphoid structure signature in digital H&E slides as a prognostic biomarker in cutaneous melanoma (Grand Ballroom AB - George R. Brown Convention Center) - Oct 4, 2024 - Abstract #SITC2024SITC_1862; P3 (NCT01274338).1 The multi-resolution HookNet model implemented in HookNet-TLS leverages both contextual information and high-resolution details to identify structures visible at lower magnifications and capture subtle differences at higher magnifications...The significant correlation between higher normalized TLS density and improved OS underscores the prognostic value of TLS in cancer immunotherapy. These findings highlight the potential of AI-driven approaches to standardize TLS assessment using low-cost H&E staining, which has a great translational impact in real-world practice.

In situ rAPMV-4 tumor vaccination achieves complete responses, long-term antitumor immunity with systemic tumor clearance, priming response to sub-therapeutic dosing of aCTLA-4 in colorectal carcinoma (Exhibit Halls AB - George R. Brown Convention Center) - Oct 4, 2024 - Abstract #SITC2024SITC_985; Considering the observed induction of immune signatures associated with response to CTLA-4 blockade by APMV-4, as well as some clinical precedent for use of Ipilimumab in CRC, we strategically developed a combinatorial treatment regimen to supplement APMV-4 in situ vaccination with a single, low-dose administration of aCTLA-4...Conclusions All in all, the described combinatorial approach serves as a proof-of-principle for future translation to the clinic, as co-administration with APMV-4 will allow for reduced dosage and frequency of CTLA-4-blocking antibodies. Ultimately, this will prevent development of life-threatening adverse effects that currently limit aCTLA-4 usage in the clinic, while maximizing likelihood of response to therapy.
