Association of pathologic complete response with the 27-gene IO score and week 3 IOpath response following neoadjuvant pembrolizumab +/- intralymphatic cytokines in the neoIRX trial (SABCS 2023)
Subjects with stage II-III TNBC were randomized 1:1 (n=12) to receive induction pembrolizumab (200mg IV) +/- peri-areolar IRX-2 (IRX-2 arm: 1 ml SQ x2 daily for 10 days + cyclophosphamide 300 mg/m2 IV x 1) preceding initiation of pembrolizumab + NAC... A subset of TNBCs experience brisk IO response following single-cycle IO (IOpath response), which is associated with 100% pCR in this preliminary dataset, highlighting IOpath as a potential surrogate biomarker to guide NAC de-escalation or omission in early-stage TNBC. Baseline 27-gene IO score predicts pCR and week 3 IOpath response. A future study is planned (neoINBRX) to evaluate the feasibility of combining baseline IO score with week 3 IOpath response to identify and treat IO-sensitive tumors with chemotherapy-sparing IO combination therapy.

LATPS, a novel prognostic signature based on tumor microenvironment of lung adenocarcinoma to better predict survival and immunotherapy response. (PubMed, Front Immunol)
Survival analysis in 28 advanced lung cancer patients treated with an anti-PD-1 regimen at Nanfang hospital revealed that the LATPS-low subgroup had better immunotherapy benefit. LATPS is an effective predictor to distinguish survival, immune characteristics, and immunotherapy benefit in LUAD patients.

The neoIRX trial: locoregional cytokine therapy to promote immunologic priming and enhanced response to neoadjuvant pembrolizumab plus chemotherapy in triple negative breast cancer (TNBC) (SABCS 2021)
Background: In stage II/III TNBC, pembrolizumab when combined with chemotherapy (doxorubicin, cyclophosphamide, paclitaxel [ACT], and carboplatin) improves event free survival and pathologic complete response (pCR) rate (Keynote-522 study)...2 Page, DB. Clin Cancer Res 2020; 26.7:1595-1605.

neoIRX: a phase II trial of locoregional cytokine therapy to promote immunologic priming and clinical response to neoadjuvant pembrolizumab plus chemotherapy in triple negative breast cancer (TNBC) (SITC 2021)
Background Background: The FDA has approved pembrolizumab in combination with neoadjuvant chemotherapy (doxorubicin, cyclophosphamide, paclitaxel [ACT], and carboplatin) for stage II/III TNBC, on the basis of improved event free survival (EFS) and pathologic complete response (pCR) rate in the Keynote-522 study.1 Novel combination immunotherapy strategies may further improve outcomes and allow the opportunity to de-escalate the chemotherapy backbone, potentially mitigating grade III/IV toxicities which occurred in 81% of recipients...As of 7/28/2021, n=7/30 subjects are enrolled (Providence Cancer Institute, Portland, OR, Providence St. John’s Cancer Institute, Santa Monica, CA, Baylor Medicine, Houston, TX).

[VIRTUAL] QuPath versus InForm: Digital image analysis of multiplex immunofluorescence (mIF) tumor-infiltrating lymphocyte (TIL) outcomes in an immunotherapy clinical trial (AACR 2021)
Exploratory mIF biomarker outcomes in clinical trials may depend on the method of image analysis. Further work is ongoing to evaluate and improve upon discordant results using QuPath v. InForm. These data also highlight the importance of collaborative efforts via the NIH Cancer Immune Monitoring and Analysis Centers to standardize and validate mIF methodologies across institutions.

Multiplex immunofluorescence to measure dynamic changes in tumor-infiltrating lymphocytes and PD-L1 in early-stage breast cancer. (PubMed, Breast Cancer Res)
P1; mIF is useful for quantifying treatment-related dynamic changes in sTILs/PD-L1 and is concordant with clinical assays, but with greater precision. Hierarchical linear modeling can mitigate the effects of intratumoral heterogeneity on immune cell count estimations, allowing for more efficient detection of treatment-related pharmocodynamic effects in the context of clinical trials.

[VIRTUAL] Concordance of multispectral immunofluorescence (mIF) with programmed death ligand 1 (PD-L1) and stromal tumor infiltrating lymphocyte (sTILs) clinical assays in early-stage breast cancer (BC). (ASCO 2020)
mIF is concordant with SP142 and sTIL prognostic assays, but with increased precision to quantify treatment related changes. Regression modeling can dramatically improve the utility of mIF as a surrogate immune-based biomarker. Our approach is being utilized in ongoing phase II studies to compare the activity of pembrolizumab +/- locoregional cytokines (IRX-2) in triple negative BC, and paclitaxel/trastuzumab +/- pembrolizumab +/- pertuzumab in HER2-positive BC.

Multispectral immunofluorescence (mIF) to detect dynamic changes in PD-L1 expression, immune cell (IC) infiltration, and tumor-IC interactions in primary breast cancer (BC) immuno-oncology (I-O) clinical trials (SABCS 2019)
Introduction: Anti-PD-1/L1 (atezolizumab) is effective in first-line, PD-L1-positive triple negative breast cancer, however it is becoming increasingly apparent that the majority of breast cancers will require novel I-O combination strategies... We describe a framework for use of mIF as a high-dimensional biomarker for use with I-O clinical trials to gain mechanistic insight into the biologic effects of I-O therapies in primary BCs. mIF can be used to detect dynamic changes in sTIL score and IC PD-L1 expression, and therefore may serve to complement the H&E sTIL score and SP142 PD-L1 clinical assay in the context of I-O clinical trials. The greater precision of regression-assisted mIF may facilitate discovery of treatment-related I-O effects, potentially with smaller sample size requirements.
