    Abstract

    Background

    RP2 is an enhanced potency oncolytic herpes simplex virus (HSV) -1 expressing GM-CSF, a fusogenic protein (GALV-GP R-), and an anti-CTLA-4 antibody-like molecule that is being evaluated in an open-label, multicenter, phase 1 clinical trial as monotherapy and combined with nivolumab (nivo). Here, we present updated safety, efficacy, and biomarker data of RP2 ± nivo.

    Methods

    After determination of the RP2D (106 PFU/mL intratumorally (IT) once followed by up to 7 additional doses of 107 PFU/mL via IT), a cohort of 30 patients (pts) was enrolled and treated with RP2 combined with nivo (240 mg Q2W for 4 months from the second RP2 dose, then 480 mg Q4W for 20 months). Responses were assessed using modified RECIST v1.1.

    Results

    Objective responses with RP2 monotherapy were observed in 3 out of 9 pts including 1 CR for ≥15 months in mucoepidermoid carcinoma, 1 PR for ≥18 months in esophageal cancer with liver metastases, 1 PR in uveal melanoma with liver metastases that progressed at 15 months. Objective responses with RP2 + nivo treatment were 44.4% in cutaneous melanoma (4/9), 25% in uveal melanoma (2/8), and 33% in SCCHN (1/3) pts. All seven responding patients had previously failed anti-PD-1 therapy, with all but one response durable to date for >425 days. The most common adverse events (grade 1-2) were pyrexia, chills, influenza-like illness, fatigue, and pruritus. No grade 4-5 events were observed. Immunohistochemistry (IHC) analysis indicated robust increases in CD8 T cell influx, PD-L1 expression, and an increase in the CD8/foxp3+ cell ratio. Clinical responses were independent of baseline CD8 T cell infiltration, PD-L1 expression levels, and prior anti-PD-1 therapy status.

    Conclusions

    RP2 ± nivo demonstrated good tolerability and durable systemic responses in pts with difficult-to-treat, heavily pretreated and anti-PD-1 failed advanced cancers. These data continue to support the hypothesis that oncolytic delivery of anti-CTLA-4 into tumors, with accompanying antigen release, presentation and immune activation, can provide potent systemic anti-tumor effects.

    Abstract

    Background

    Cancer-Associated Fibroblasts (CAFs) are a main component of the tumour microenvironment. Recent evidence suggests that high levels of CAFs correlate with poorer prognosis and a pro-tumorigenic microenvironment. The clinical relevance of CAF presence and the mechanisms by which they influence prognosis warrant further research.

    Methods

    We used publicly available RNAseq data from The Cancer Genome Atlas (TCGA), gene expression data from cancer-cell (CC)-CAF co-cultures of three different cell lines. Further in vitro validation experiments were performed on human Head and Neck cancer cell lines, patient derived CAFs and macrophages from healthy donors.

    Results

    We generated a gene signature that predicts the abundance of CAF/CC interaction in clinical RNAseq data from a meta-analysis of transcriptomic data derived from Cancer Cell (CC) and CAF co-cultures. This gene signature is predictive of worse overall survival in datasets of Squamous Cell Carcinoma (SCC) patients. CAF abundance and the co-culture signature are strongly correlated with RAS signalling. Mechanistically, we showed that AP-1 transcription factor genes are strongly up-regulated when CCs and CAFs are in close contact. Direct contact between CCs and CAFs upregulates the RAS pathway in both cell types through membrane bound growth factors and growth factor receptors, activating AP-1 activity. We also demonstrated that the RAS / AP-1 axis is used by CCs to induce secretion of pro-tumorigenic and immune-inhibitory cytokines from CAFs, enhancing migration of potentially immune-suppressive macrophages. Of note, patients with high expression of CC-CAF coculture genes show an immune-suppressive microenvironment. Importantly, treatment with ERK inhibitors is able to disrupt the activation of this pathway, blocking cytokine production and impairing macrophage migration.

    Conclusions

    In conclusion, we generated a gene signature predictive of overall survival in SCC patients, linked to cancer cell -CAF interaction and RAS signalling. This study reveals a novel mechanism of crosstalk between CCs and CAFs able to modulate the tumour immune microenvironment.

    Abstract

    Background

    This study will assess whether setanaxib, an investigational nicotinamide adenine dinucleotide phosphate oxidase (NOX) 1/4 inhibitor (Calliditas Therapeutics Suisse SA), could increase cancer-associated fibroblast (CAF)-rich tumour response to pembrolizumab in patients (pts) with recurrent/metastatic squamous cell carcinoma of the head and neck (rmSCCHN). Pembrolizumab, a programmed cell death-1 inhibitor, is indicated as first-line treatment (tx) for rmSCCHN in some pts; however, tumour response rates are low.1,2 CAF-rich tumours suppress response to immunotherapy by excluding cluster of differentiation (CD)8+ tumour-infiltrating lymphocytes (TILs).3NOX1/4 are key drivers of fibrogenesis. Pre-clinical models suggest that, as NOX4 inhibition by setanaxib may prevent and reverse differentiation of CAFs, combination tx of setanaxib with pembrolizumab may improve clinical outcomes in CAF-rich tumours.3

    Trial design

    In this double-blind, placebo-controlled phase 2 trial (NCT05323656), 60 pts with rmSCCHN (Table) will be randomised 1:1 (stratified by tumour human papillomavirus status) to oral setanaxib 800 mg twice daily or placebo, plus intravenous pembrolizumab 200 mg every 3 weeks, for ≤24 months. The primary objective will be to evaluate and compare best percentage change from baseline in tumour diameter (using Response Evaluation Criteria in Solid Tumours [RECIST] 1.1) between tx arms. Key secondary objectives will include comparisons of progression-free survival per RECIST 1.1 and change from baseline in tumour CAF and CD8+ TIL levels between tx arms. The study is currently recruiting in France, Germany, Poland, Spain, the UK and the USA. 1NICE https://www.nice.org.uk/guidance/ta661/ accessed 13/04/22; 2Bauml J Clin Oncol 2017;35:1542–9; 3Ford K Cancer Res 2020;80:1846–60.

    Abstract

    Background

    In PROpel (NCT03732820), pts were enrolled irrespective of HRR gene mutation (HRRm) status. However, determination of HRRm and evaluation of radiographic progression-free survival by HRRm status were predefined endpoints. TT testing is considered the reference for assessment of HRRm but, given potential challenges in obtaining sufficient quantity of quality TT, ctDNA testing was also conducted.

    Methods

    Archival TT and blood samples were collected at baseline from >98% of randomised pts and analysed by the FoundationOne®CDx and FoundationOneLiquid®CDx molecular diagnostic tests, respectively. HRRm status (HRRm, non-HRRm or HRRm unknown) was assigned by individual test result and using an aggregate of the results from both tests. For aggregate results, pts were classified as HRRm if an HRRm was detected by either test; non-HRRm if no HRRm was detected by either test; or HRRm unknown if they did not have a valid HRRm test result.

    Results

    Of the 796 pts randomized, 782 had TT samples and 794 had blood samples available for testing. Of the pts with TT samples, 535 (68%) were successfully assessed for HRRm status by TT test, while 734 (92%) of pts with blood samples were successfully assessed by ctDNA test. Aggregate HRRm status was obtained for 778 (98%) pts (226 HRRm, 552 non-HRRm and 18 HRRm unknown). Using TT as a reference, positive-percent agreement was 80%, negative-percent agreement was 87%, overall-percent agreement was 85% and the positive and negative predictive values were 64% and 94%, respectively. In the HRRm by ctDNA subgroup 51 pts were non-HRRm by TT. The negative predictive value suggests that in the non-HRRm by ctDNA subgroup ∼174/186 (94%) pts would also be non-HRRm by TT test. Therefore, there were ∼12 potential false negative results by ctDNA test in the total non-HRRm aggregate population (2% of 552 pts).

    Conclusions

    There was good agreement between matched TT and ctDNA test results in PROpel. Using aggregate test results, it was possible to maximize the number of pts with known HRRm status while controlling the number of potential false negative results, thus facilitating robust analysis of HRRm status.

    Abstract

    Background

    Many patients (>75%) diagnosed with breast cancer in Ireland today will be cured and are at risk of dying from other cancers and non-communicable diseases. Breast cancer diagnosis provides a pivotal time point for education on modifiable risk factors and engagement with secondary risk reduction services. Our study set out to establish the level of awareness and acceptability of these areas, respectively.

    Methods

    A survey was developed for breast cancer survivors and oncology clinicians using previously validated questionnaires; the ‘Mitchelstown Cohort Survey’ and the ‘International Physical Activity Questionnaire’. IBM SPSS software (Version 28.0) was used for data analysis.

    Results

    Between September and December 2021, 322 patients and 29 clinicians attending the South Infirmary Victoria and Cork University Hospitals, completed the survey. Over 80% of patients and clinicians were aware of modifiable cancer risk factors. Only 1 in 5 clincians had training in secondary risk reduction however 90% of clinicians were willing to refer to services. Education had an impact on the likelihood of patient engagement (Table). Patients who smoked, had increased alcohol intake, or gained weight since diagnosis were more likely to engage with services (p=<.001, p=<.001, p=0.015 respectively). Patients who made changes to activity levels since diagnosis were more likely to engage with exercise education (p=0.015).

    Exercise education 199/318 13 52 134 0.139

    Conclusions

    This study identified that over 4 in 5 breast cancer survivors and oncology clinicians were aware of the importance of modifiable lifestyle risk factors. While 9 in 10 clinicians were willing to refer to secondary prevention services if available, the likelihood of patient engagement was associated with their ‘at risk’ behaviours and education level. Our study highlights the challenges of implementing health promotion programs in this cohort.
