16P Neutrophil-lymphocyte ratio as a prognostic marker in a resource constraint setting for metastatic malignancies treated with immune checkpoint inhibitors
ConclusionPatients with low NLR had a significantly better response rate and overall survival. In a resource and cost constraint setting, a simple inexpensive test such as NLR would not only be prognostic, but can help in choosing treatment strategies in scenarios where PDL-1 expression does not carry any implication such as in 2nd line mRCC and 2nd line mNSCLC. Also with the advent of combination regimens in 1st line setting (chemo+ ICI in mNSCLC and oral TKI+ICI in mRCC), large scale studies need to be done on whether those with low NLR can benefit with only single agent ICI which would have an impact in not only lowerin...

143P Association of PTPRT mutation with survival of immune checkpoint inhibitor in patients with cancer
ConclusionWe demonstrated that PTPRT mutation can predict survival benefit from cancer ICI therapy. PTPRT mutation might be an important component of the immunogenetic landscape and should be integrated into predictive biomarker panels for ICI therapy and be validated in future prospective clinical trials.Legal entity responsible for the studyHerui Yao.FundingThis study was supported by grants from the National Natural Science Foundation of China (81372819, 81572596, U1601223), the Natural Science Foundation of Guangdong Province (2017A030313828), the Guangzhou Science and Technology Program (201704020131), the Sun Yat-Sen...

33P Tumour mutational burden ring trial: Evaluation of targeted next-generation sequencing platforms for implementation in clinical practice
ConclusionOur data show that assays from different providers can be used to predict TMB. However, samples with a TMB value around the cut-off of 10 mut/Mb are challenging and interpretation should occur with caution. Further studies are required before implementing these assays in routine clinical diagnosis.Legal entity responsible for the studyThe authors.FundingBristol-Myers Squibb.DisclosureS.

92O Nivolumab plus low-dose ipilimumab as first-line treatment of advanced NSCLC: Overall survival analysis of checkmate 817
ConclusionSelect TRAE profile of NIVO + low-dose IPI was similar between cohorts A and A1. Durable OS outcomes were observed with first-line NIVO+IPI in patients with advanced NSCLC (cohort A) and were comparable to CheckMate 227; although as expected, comorbidities and/or poor performance status impacted outcomes in cohort A1.Clinical trial identificationNCT02869789.Editorial acknowledgementWriting and editorial assistance was provided by Mhairi Laird, PhD, of Caudex and funded by Bristol-Myers Squibb.Legal entity responsible for the studyBristol-Myers Squibb.FundingBristol-Myers Squibb.DisclosureF.

69P Clinical biomarkers as predictors of immunotherapy (IT) benefit in recurrent/metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) patients (pt)
ConclusionIn our cohort, Alb levels and BMI were strong factors predicting outcomes of IT-treated R/M HNSCC pt. These results suggest that NS should be considered when stratifying pt in ongoing trials. In addition, the lack of prognostic value of dNLR and LDH levels deserves further investigation.Legal entity responsible for the studyVall d'Hebron Institute of Oncology.FundingHas not received any funding.DisclosureAll authors have declared no conflicts of interest.

127TiP PROPEL: A phase I/II trial of bempegaldesleukin (NKTR-214) in combination with pembrolizumab (pembro) in patients (pts) with advanced solid tumours
AbstractBackgroundCheckpoint Inhibitors (CPIs), are now part of standard treatment in many advanced solid tumors, including metastatic non-small cell lung cancer (mNSCLC). However, novel, more effective CPI combinations are needed to broaden, deepen, and prolong responses, especially for pts with poor prognostic features or negative predictive clinical factors for CPI benefit, including PD-L1 negative (-) status. Bempegaldesleukin (BEMPEG; NKTR-214) is a CD122-preferential IL-2 pathway agonist designed to provide sustained signaling through the IL-2 βγ receptor. BEMPEG + CPI has demonstrated promising efficacy and can co...

155P Interleukin 17F and vasculogenic mimicry: Potential therapeutic targets in oral tongue cancer?
ConclusionOur findings confirm the role of VM in OTSCC carcinogenesis. Here, we suggest that IL-17F counteracts the tumorigenic activity in OTSCC, in part, through the antiangiogenic effect in the tumour microenvironment, and hence further studies are warranted. Harnessing IL-17F in the current management approaches in advanced OTSCC patients may lead to promising immunotherapeutic strategies against OTSCC.Legal entity responsible for the studyUniversity of Helsinki.FundingUniversity of Helsinki, Doctoral program in clinical research (KLTO).DisclosureThe author has declared no conflicts of interest.
