TPS179 Background: Tumor mutational burden (TMB) is an emerging biomarker for immune checkpoint inhibitors (ICIs) in non-small cell lung cancer (NSCLC). Analysis of circulating tumor DNA (ctDNA) has been reported to effectively identify patients likely to respond to ICIs by effectively and non-invasively evaluating the TMB in the tumor in NSCLC and gastric cancer. Methods: We are conducting an investigator-initiated multicenter phase II basket trial to investigate efficacy and safety of nivolumab monotherapy in patients with advanced gastrointestinal (GI) cancers with high bTMB identified by ctDNA analysis as part of the Nationwide Cancer Genome Screening Project (SCRUM-Japan GI-SCREEN). Eligibility criteria include histologically confirmed unresectable or recurrent GI malignancies; ECOG PS of 0 or 1; refractory or intolerant to the standard therapies; and high bTMB identified by a 73-gene sequencing ctDNA panel (Guardant360) regardless of microsatellite instability status. Patients will be enrolled into one of four disease-specific cohorts (colorectal, gastric, esophageal, and other GI cancer cohort), and receive intravenous nivolumab monotherapy of 360 mg every 3 weeks. The bTMB score is calculated by adjustment of mutation count by tumor fraction, and tentative bTMB level cut-offs were determined according to objective response rate (ORR) reported for ICI treatment for each tumor subtype in previous trials. The trial will utilize a two-stage design with a Bayesian hierarchical model, and tentative bTMB level cut-off will be re-assessed in the first stage. Primary endpoint in each stage is the disease control rate at 6 week and the ORR assessed by investigators per RECIST v1.1, respectively. Target sample size is determined as 70 in total so that the statistical power in each disease-specific cohort calculated based on a Bayesian posterior distribution attains 70 to 80% with one-sided alpha level in each cohort of approximately 10%. For biomarker analysis, tumor tissue and ctDNA will be serially collected and analyzed by whole-exome, transcriptome, and T cell receptor sequencing. This trial was initiated since September 2018. Clinical trial information: UMIN000033182.

Tumor Mutational Burden

TPS5597 Background: Immunotherapy has improved outcomes for patients with recurrent or metastatic cervical cancer whose tumors express PD-L1. Pembrolizumab (PEM), a monoclonal antibody that binds to programmed cell death 1 (PD 1) receptor, inhibits interaction with programmed cell death ligand 1 (PD-L1) and programmed cell death ligand 2 (PD-L2). It is approved for the treatment of recurrent or metastatic cervical cancer. Despite promising results, new strategies are being developed to improve immunotherapy responses. This includes DNA-damaging agents that have the potential to enhance the response to immunotherapy by promoting neo-antigen release, increasing tumor mutational burden, and enhancing PD-L1 expression. Poly-ADP-ribose polymerase (PARP) inhibitors, such as olaparib, have shown synergy with immunotherapy in preclinical and early clinical studies. PARP-based therapy is based on the inhibition of single-strand DNA repair, leading to DNA damage and increased tumor mutational burden. As a result, the tumor becomes a more attractive target for immunotherapy. Based on this, we are investigating the interplay between homologous recombination (HR) repair deficiency, another mechanism of DNA repair, and solid tumor response to ICI. Our approach uses an all-inclusive functional immunofluorescence assay of the Fanconi Anemia triple-staining immunofluorescence (FATSI) we developed and can be performed in paraffin-embedded tumors. Methods: This is a phase II open-label single center trial evaluating the role of PEM and olaparib in patients with metastatic cervical cancer who have progressed on first-line standard of care chemotherapy. FATSI will be performed in all patients. We hypothesize that FATSI negative tumors will be associated with improved responses. Other eligibility criteria include measurable disease by imaging, 18 years of age or older, and no previous exposure to ICI or PARP inhibitor. The primary objective is to evaluate the immune-related objective response rate (iORR) achieved in patients with FA Repair Pathway functionally competent and functionally deficient tumors. Secondary objectives include 20-week progression free survival and overall survival. Other exploratory objectives include evaluation of the mutation load and markers of neo-antigenicity, T cell receptor clonotype analyses (before and after treatment), and alterations in HR repair genes. We will utilize a two-stage phase II design to detect an iORR ≥ 20% in the whole population tested vs. the null hypothesis that the true iORR ≤5%, represents a response by chance alone or other infrequent unknown mechanisms. An interim analysis requires at least 2 of the first 20 evaluable patients enrolled have an objective response. If this occurs, we will accrue 28 additional patients to total 48. Enrollment is ongoing and two patients are currently on treatment. Clinical trial information: NCT04483544.

Biomarker Analysis

TPS540 Background: First-line treatment of patients (pts) with advanced/metastatic UC consists of platinum-based CT, with no well-established subsequent therapy for platinum-refractory disease. Although checkpoint inhibitors have shown promising results recently, targeted agents have generally not demonstrated significant clinical activity in this setting. Around 20% of UC harbor ERBB family genetic alterations, as such it may be a suitable therapeutic target (Knowles, Nat Rev Cancer 2015;15:25–41). The irreversible ERBB family blocker, afatinib, has shown activity in a Phase II trial in a subset of pts with UC who had ERBB2/ERBB3 aberrations (Choudhury, J Clin Oncol 2016;34:2165–71). This Phase II trial will evaluate afatinib in pts with UC molecularly selected for ERBB receptor alterations. Methods: This single-arm trial will assess the efficacy and safety of afatinib in pts with UC harboring ERBB2/ERBB3 mutations or ERBB2 amplification (Cohort A), or EGFR (ERBB1) amplification (Cohort B). Eligible pts are ≥18 years of age with ECOG PS 0–1, histologically confirmed advanced/metastatic UC of the bladder, upper tract or urethra, not amenable to surgery and progressing during or after platinum-based CT, with available archival tissue samples for pre-screening biomarker analysis. Pts will receive oral afatinib 40 mg/day until disease progression or discontinuation. Cohort A is enrolling in two stages, with Stage 2 enrollment based on anti-tumor activity observed. The primary endpoint is progression-free survival (PFS) rate at 6 months; secondary endpoints include objective response rate, PFS, overall survival, disease control rate, duration of response and tumor shrinkage. Trial objectives will be analyzed separately for the two cohorts. Safety and biomarker assessments will also be performed. The trial commenced in June 2016; as of October 4, 2017, 201 samples have been analyzed, with 24.3% and 8% of pts with genetic alterations potentially eligible for inclusion in Cohort A and B, respectively. To date, 12 pts have received study treatment in Cohort A and 6 in Cohort B; recruitment is ongoing. Clinical trial information: NCT02780687.

5523 Background: Microsatellite instability (MSI-H) is a biomarker for response to immune-checkpoint inhibitors (ICIs); however, these neoplasms are heterogenous including Lynch (germline), Lynch-like (somatic) and sporadic ( MLH1-methylated) tumors. Whether mechanisms underlying MSI alter responses to ICIs is unclear. We report data from a phase II pilot study (NCT02899793) of pembrolizumab in recurrent MSI-H endometrial cancer (EC) patients and potential mechanisms of primary/secondary ICI resistance. Methods: Patients with measurable, MSI-H EC confirmed by immunohistochemistry and polymerase chain reaction were evaluated by next-generation sequencing and received pembrolizumab 200 mg intravenously every 3 weeks for up to 2 years. The primary end point was objective response rate (ORR) per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Results: Twenty-five patients (24 evaluable) were treated. Six (25%) patients harbored Lynch/Lynch-like tumors while 18 (75%) had sporadic EC. Tumor mutational burden (TMB) was higher in Lynch-like (median 2939, IQR:867-5108) versus sporadic tumors (median 604, IQR:411-798) ( P= 0.0076). Median follow-up was 25.8 months with an ORR of 58% (95% CI, 36.6-77.9%). ORR was 100% in Lynch/Lynch-like patients but only 44% in sporadic patients ( P= 0.024). The 3-year progression-free (PFS) and overall survival (OS) proportions were 100% versus 30% ( P= 0.017) and 100% versus 43% ( P= 0.043), respectively. Grade 3/4 treatment-related adverse events (6.8%) occurred in 12 patients. Defective antigen processing/presentation and deranged induction in interferon responses served as mechanisms of resistance in sporadic MSI-H EC. Conclusions: Our study demonstrated prognostic significance of Lynch-like versus sporadic MSI-H EC on ORR, PFS and OS when treated with pembrolizumab. Clinical studies evaluating separate subtypes of MSI-H EC treated with ICIs are warranted. Clinical trial information: NCT02899793.

BackgroundAngiosarcoma is a rare cancer of endothelial cells that can be aggressive and carries a high mortality. A subset of angiosarcomas are characterized by high tumor mutational burden (TMB) and UV light exposure DNA mutational signature. Isolated case reports have suggested clinical efficacy of immune checkpoint blockade in angiosarcoma; no prospective studies of immune checkpoint inhibition in angiosarcoma have been reported. We report efficacy analysis results for patients with advanced or unresectable angiosarcoma treated with ipilimumab and nivolumab as a cohort of an ongoing phase II study for rare cancers (NCT02834013).MethodsThis is a prospective, open-label, multicenter phase II clinical trial of ipilimumab (1mg/kg IV q6weeks) plus nivolumab (240mg IV q2weeks) for patients with metastatic or unresectable angiosarcoma. Primary endpoint is objective response rate as assessed by RECIST v1.1, including measurable cutaneous disease that can be followed by photography. Secondary endpoints include PFS, OS, stable disease at six months, and toxicity. A two-stage design is used with six patients in the first stage and an additional ten patients in the second stage.ResultsAt data cutoff, 16 patients with angiosarcoma were enrolled. Median age was 68 years (25-81 years). Median number of prior lines of therapy was 2 (0-5). 9 patients had cutaneous primary tumors of any cutaneous site, 7 had non-cutaneous primary tumors. ORR for all patients was 25% (4/16, table 1, figure 1). Subgroup analysis revealed that 60% (3/5) of patients with primary cutaneous tumors of the scalp or face had a confirmed objective response. 6-month PFS was 38%. 75% of patients experienced an adverse event (AE), and 25% experienced a grade 3-4 AE. 68.8% experienced an immune related AE (irAE), and 2 (12.5%) developed grade 3 or 4 irAEs. Grade 3-4 irAEs were ALT and AST increase and diarrhea. There were no grade 5 toxicities.ConclusionsThe combination of ipilimumab and nivolumab was well tolerated and had an ORR of 25% in angiosarcoma regardless of primary site, with 3 of 5 patients with cutaneous tumors of the scalp or face responding. Ipilimumab and nivolumab warrant further investigation in angiosarcoma.AcknowledgementsFunding: National Institutes of Health/National Cancer Institute grant awards CA180888, CA180819, CA180868; and in part by Bristol-Myers Squibb CompanyTrial RegistrationNCT02834013Ethics ApprovalThis study was approved by the NCI CIRB.

TPS9594 Background: Immune checkpoint inhibitors (ICI) have transformed treatment for patients (pts) with advanced melanoma, as have BRAF/MEK inhibitors for pts with BRAF V600-mutant melanoma. However, pts with acral or mucosal melanomas are in particular need of more options given a lower objective response rate (ORR) to ICI, and lower incidence of BRAF V600 driver mutation. Such BRAF mutations are found in only 5-10% of acral/mucosal melanomas, while KIT mutations/amplifications are found in 10-20%. Even when present, a KIT alteration does not guarantee response to KIT inhibition, with only about one-third responding as previously shown in 3 phase II studies. A significant number of KIT-mutant melanomas have been shown to demonstrate NF1 or SPRED1 loss, with recent preclinical work showing that such alterations are associated with the loss of negative suppression of RAS, resulting in RAS activation and MEK dependence. We hypothesize that NF1 or SPRED1 loss cooperates with KIT mutations to drive melanomagenesis and resistance to KIT inhibition, and propose to target this vulnerability with a combination approach to targeted therapy. This phase II study will be the first to evaluate the efficacy and safety of binimetinib plus imatinib in pts with KIT-mutant melanoma. Methods: This is an investigator-initiated phase II study of binimetinib in combination with imatinib in pts with BRAF V600 WT, KIT-mutant unresectable melanoma who have progressed on or who are ineligible for ICI (NCT04598009). Pts will be ≥18 yo with performance status ECOG 0-2, and have unresectable Stage IIIB/C/D or Stage IV melanoma that is BRAF V600 WT and KIT-mutant by CLIA-certified testing platform. Pts will have progressed on prior ICI or other standard-of-care (SOC) therapies, or be ineligible for or unable to tolerate SOC therapies. Pts with brain metastasis will be eligible if clinically stable and determination made that no CNS-specific treatment is required prior to study start. Pts previously treated with a MEK inhibitor will be excluded. A Simon 2-stage Minimax design will be used; the null hypothesis that the true response rate is 0.1 will be tested against a one-sided alternative. 15 pts will be accrued in the first stage. If there are £1 responses, the study will be stopped. Otherwise, 10 additional pts will be accrued for a total of 25. The null hypothesis that the true response rate is 0.1 will be rejected if ≥6 responses are observed. This yields a type I error rate of 0.05 and power of 0.8017 when the true response rate is 0.3.Primary endpoint: ORR (RECIST). Secondary endpoints: duration of response, progression-free survival, overall survival, clinical benefit rate (CR, PR, or SD ≥16 weeks), safety profile (CTCAE). Exploratory objectives to include investigations of association between clinical response and baseline NF1 and SPRED1 status, and of pathologic correlates of acquired resistance. Study began enrolling pts in December 2020 and is ongoing. Clinical trial information: NCT04598009.

Immunotherapy, represented by immune checkpoint inhibitors (ICI), is transforming the treatment of cancer. However, only a small percentage of patients show response to ICI, and there is an unmet need for biomarkers that will identify patients who are more likely to respond to immunotherapy. The fundamental basis for ICI response is the immunogenicity of a tumor, which is primarily determined by tumor antigenicity and antigen presentation efficiency. Here, we propose a method to measure tumor immunogenicity score (TIGS), which combines tumor mutational burden (TMB) and an expression signature of the antigen processing and presenting machinery (APM). In both correlation with pan-cancer ICI objective response rates (ORR) and ICI clinical response prediction for individual patients, TIGS consistently showed improved performance compared to TMB and other known prediction biomarkers for ICI response. This study suggests that TIGS is an effective tumor-inherent biomarker for ICI-response prediction.

The emergence of cancer immunotherapy has already shown some remarkable results, having changed the treatment strategy in clinical practice for solid tumors. Despite these promising long-term responses, patients seem to lack the ability to respond to immune checkpoint inhibitors, thus demonstrating a primary resistance to immunotherapy. Moreover, a significant number of patients who initially respond to treatment eventually acquire resistance to immunotherapy. Both resistance mechanisms are a result of a complex interaction among different molecules, pathways, and cellular processes. Several resistance mechanisms, such as tumor microenvironment modification, autophagy, genetic and epigenetic alterations, tumor mutational burden, neo-antigens, and modulation of gut microbiota have already been identified, while more continue to be uncovered. In this review, we discuss the latest milestones in the field of immunotherapy, resistance mechanisms against this type of therapy as well as putative therapeutic strategies to overcome resistance in solid tumors.

Tumor Mutational Burden

Immune checkpoint inhibitors are now a cornerstone of treatment for non-small cell lung cancer (NSCLC). Tissue-based assays, such as Programmed cell death protein 1 (PD-L1) expression or mismatch repair deficiency/microsatellite instability (MMRD/MSI) status, are approved as treatment drivers in various settings, and represent the main field of research in biomarkers for immunotherapy. Nonetheless, responses have been observed in patients with negative PD-L1 or low tumor mutational burden. Some aspects of biomarker use remain poorly understood and sub-optimal, in particular tumoral heterogeneity, time-evolving sampling, and the ability to detect patients who are unlikely to respond. Moreover, tumor biopsies offer little insight into the host’s immune status. Circulating biomarkers offer an alternative non-invasive solution to address these pitfalls. Here, we summarize current knowledge on circulating biomarkers while using liquid biopsies in patients with lung cancer who receive treatment with immune checkpoint inhibitors, in terms of their potential as being predictive of outcome as well as their role in monitoring ongoing treatment. We address host biomarkers, notably circulating immune cells and soluble systemic immune and inflammatory markers, and also review tumor markers, including blood-based tumor mutational burden, circulating tumor cells, and circulating tumor DNA. Technical requirements are discussed along with the current limitations that are associated with these promising biomarkers.

Tumor Immunogenicity

Despite therapeutic advances, lung cancer (LC) is one of the leading causes of cancer morbidity and mortality worldwide. Recently, the treatment of advanced LC has experienced important changes in survival benefit due to immune checkpoint inhibitors (ICIs). However, overall response rates (ORR) remain low in unselected patients and a large proportion of patients undergo disease progression in the first weeks of treatment. Therefore, there is a need of biomarkers to identify patients who will benefit from ICIs. The programmed cell death ligand 1 (PD-L1) expression has been the first biomarker developed. However, its use as a robust predictive biomarker has been limited due to the variability of techniques used, with different antibodies and thresholds. In this context, tumor mutational burden (TMB) has emerged as an additional powerful biomarker based on the observation of successful response to ICIs in solid tumors with high TMB. TMB can be defined as the total number of nonsynonymous mutations per DNA megabases being a mechanism generating neoantigens conditioning the tumor immunogenicity and response to ICIs. However, the latest data provide conflicting results regarding its role as a biomarker. Moreover, considering the results of the recent data, the use of peripheral blood T cell receptor (TCR) repertoire could be a new predictive biomarker. This review summarises recent findings describing the clinical utility of TMB and TCRβ (TCRB) and concludes that immune, neontigen, and checkpoint targeted variables are required in combination for accurately identifying patients who most likely will benefit of ICIs.
