67P Real-world outcomes for patients with recurrent/metastatic squamous cell carcinoma of the head and neck (R/M SCCHN) treated with nivolumab
ConclusionThis real-world study of nivolumab in R/M SCCHN patients in the United States shows that the improved survival demonstrated by nivolumab in CheckMate 141 translates into similar real-world outcomes for patients, with an even greater benefit in first-line patients. These results are consistent with other observational analyses in Europe and reinforce the survival benefit of nivolumab in R/M SCCHN patients as early as first line.Legal entity responsible for the studyBristol-Myers Squibb.FundingBristol-Myers Squibb.DisclosureP.

153P Immune-microbial crosstalk in oral epithelium: A potential role in oral carcinogenesis?
ConclusionDysregulated production of hBD-2 could enhance a proinflammatory vicious circle in OLP, which can further damage healthy neighbouring cells and may over time promote carcinogenesis. Histamine and H4R can modulate hBD-2 response in oral epithelium and may serve as promising targets for therapeutic interventions.Legal entity responsible for the studyTULES Research Group.FundingDoctoral Program in Oral Sciences, University of Helsinki.DisclosureAll authors have declared no conflicts of interest.

126TiP A phase I study of NBTXR3 activated by radiotherapy for patients with advanced cancers treated with an anti-PD-1 therapy
AbstractBackgroundThe majority of cancer patients are resistant to immune therapy; only around 15% respond to immune checkpoint inhibitors (ICI). Thus, strategies able to increase ICI response are of great interest. Recent work suggests radiotherapy (RT) can act as an immunomodulator to increase the proportion of ICI responders and improve clinical outcomes. However, RT dose and ultimate efficacy are limited by toxicity related to exposure of healthy tissues. NBTXR3 is a first-in-class radioenhancer administered by intratumoral injection, designed at the nanoscale to increase RT energy dose deposition within the tumor. The...

142P Association of MUC16 mutation with survival of immune checkpoint inhibitor in patients with cancer

15P Immune escape in acute myeloid leukemia
ConclusionThe majority of AML patients display at least one marker of immune escape at diagnosis. These include decreased HLA class I expression, reduced antigen processing, increased PDL1 expression, secretion of Tim3 by leukemia blasts, or increased Treg counts. The mechanisms of immune suppression in AML are likely heterogenous, similarly to the disease itself. Both PD-L1 and Tim-3 might have prognostic value in selected AML subgroups.Legal entity responsible for the studyThe authors.FundingMinistry of Health of the Czech Republic (Grant no 16-30268A).DisclosureAll authors have declared no conflicts of interest.

107P Increasing responses to T-cell therapies in solid tumours by the use of an engineered adenovirus coding for TNFa and IL-2
ConclusionThe use of TILT-123 to enable T-cell therapies (including checkpoint-inhibiting antibodies) delivered encouraging preclinical results pointing to it as a valuable approach to increase the number of patients that benefit from T-cell therapies. Those results include not only cell based therapies but also checkpoint inhibitors, a kind of therapy that is making the difference in the field and becoming first-line treatment for an increasing number of indications. Because of the favourable preclinical studies, the first in human clinical trials with TILT-123 will start in the upcoming months.Legal entity responsible fo...

ConclusionBaseline and 12-wk NLR may allow to distinguish between long and short-term survivors. Improved response rates and survival in our series may be explained by the lower rate of platinum-refractory disease and the use of nivolumab in the first-line setting as well as beyond progression in a substantial proportion of patients.
