Aim: To evaluate the impact of age on the efficacy of immune checkpoint inhibitors (ICI) in cancer patients. Materials & methods: The primary outcomes included overall survival (OS) and progression-free survival (PFS). Subgroup, meta-regression analysis and within-trial interaction HR were conducted. Results: A total of 34 studies containing 20,511 cancer patients were included. ICI could improve the OS and PFS in patient aged <65 and ≥65 years. Patients aged <75 years treated with ICI also had favorable OS and PFS compared with the control groups. Conclusion: ICI has comparable efficacy in cancer patients aged <65 and ≥65 years. Cancer patients aged ≥75 years need more attention in the future clinical trials.

Abstract Background Observational studies and experimental models suggest that use of antibiotics close to the administration of immune checkpoint inhibitors (ICI) can negatively affect tumor response and patient survival. This observation may be attributed to microbiome dysbiosis and the resultant suppression of host immune response against neoplastic cells. Methods We conducted a systematic search of PUBMED and EMBASE databases and references of articles retrieved. We included studies published between 1/1/17 and 2/1/20, which evaluated the association between antibiotic use and clinical outcomes in cancer patients treated with ICI. Primary endpoints were overall survival (OS), progression free survival (PFS), response rate (RR) and progressive disease (PD) rate. We performed a study-level random-effects meta-analysis with pooling of hazards ratios (HR) for OS, PFS, and odds ratios (OR) for RR and PD (PROSPERO ID: CRD42020166473). Results We included 41 studies with a total of 10,857 patients. The most common malignancies were lung cancer (59.7%), melanoma (23.1%), renal cell and urothelial carcinomas (8.1%). OS and PFS were shorter, RR lower, and PD higher in patients receiving antibiotics, both in univariate analyses and after adjustment for other confounders. Heterogeneity was significant for all outcomes, less so for adjusted OS and PFS (Table). To our knowledge, this is the largest meta-analysis on the association between antibiotic use and efficacy of ICI, and the only one to address RR and PD to-date. Association between antibiotics and clinical outcomes. Conclusion We demonstrated a significant association between antibiotic use and unfavorable clinical outcomes in patients with cancer receiving ICI. Such patients may be an important target group for antibiotic stewardship interventions. The high heterogeneity across all outcomes underscores the need for more detailed, patient-level studies with stratification by host, antibacterial and cancer treatment factors.

e15234 Background: Corticosteroids are commonly used for management of cancer-related symptoms or immune-related adverse events (irAEs) in cancer patients treated with immune checkpoint inhibitors (ICIs). However, given the inhibitory effects of corticosteroids on a broad range of immune responses, it is presumed that the use of these agents may affect the clinical outcomes of ICIs. This meta-analysis aims to explore the impact of corticosteroids use on the efficacy of ICIs in cancer patients. Methods: We conducted a search covering electronic databases (MEDLINE, EMBASE, and CENTRAL), conference abstracts (ASCO and ESMO) and reference lists to identify relevant studies. Studies that reported clinical outcomes of patients with corticosteroids administration before and/or after the initiation of ICIs treatment were eligible for evaluation. The primary outcomes included progression-free survival (PFS) and overall survival (OS). The random-effects model was utilized to synthesize the effect sizes of individual studies. Results: The initial literature search identified 1,900 records. After study selection, a total of 15 studies with 14,123 patients were included in the quantitative analysis. Corticosteroids use significantly reduced PFS (HR = 1.84; 95% CI: 1.30–2.61; P = 0.001) and OS (HR = 1.41; 95% CI: 1.18–1.68; P < 0.001) in cancer patients treated with ICIs. In subgroup analysis, corticosteroids use for cancer-related symptoms was associated with a shorter PFS (HR = 1.98; 95% CI: 1.40–2.78; P < 0.001) and OS (HR = 1.88; 95% CI: 1.25–2.83; P = 0.003), but their use for irAEs did not show a detrimental impact on OS (HR = 1.05; 95% CI: 0.77–1.44; P = 0.740). Conclusions: This meta-analysis indicated that corticosteroids use might hinder the efficacy of ICIs in cancer patients. The indications of corticosteroids use should be strictly controlled during the course of immunotherapy.

Aim: We conducted an up-to-date meta-analysis of randomized controlled trials (RCTs) to compare the immune checkpoint inhibitors (ICIs) in different age groups. Methods: The relevant RCTs in cancer patients receiving ICIs were searched and the systematic evaluation was performed. PubMed, MEDLINE and EMBASE were searched for studies published till January 2019. Results: A total of 27 RCTs included 17,546 patients were available for this meta-analysis. ICIs significantly improved overall survival (OS) and progression-free survival (PFS) in both of the younger (<65 years) and the older cancer patients (≥65 years). No significantly prolonged OS and PFS was observed among patients older than 75 years. Conclusion: ICIs could not significantly improve OS and PFS compared with controls in cancer patients aged over 75 years.

BACKGROUND: The albumin-globulin ratio (AGR) could be a prognostic biomarker in patients with cancer, although the data is limited in patients treated with immune-checkpoint inhibitors (ICIs). OBJECTIVES: We aimed to evaluate the association between AGR and survival in ICI-treated patients. METHODS: The data of 212 advanced-stage patients were retrospectively evaluated in this cohort study. The association between AGR with overall (OS) and progression-free survival (PFS) were evaluated with multivariate analyses. Additionally, receptor operating curve (ROC) analysis was conducted to assess the AGR’s predictive power in the very early progression (progression within two months) and long-term benefit (more than twelve months survival). RESULTS: The median AGR was calculated as 1.21, and patients were classified into AGR-low and high subgroups according to the median. In the multivariate analyses, patients with lower AGR (< 1.21) had decreased OS (HR: 1.530, 95% CI: 1.100–2.127, p= 0.011) and PFS (HR: 1.390, 95% CI: 1.020–1.895, p= 0.037). The area under curve of AGR to detect early progression and long-term benefit were 0.654 (95% CI: 0.562–0.747, p= 0.001) and 0.671 (95% CI: 0.598–0.744, p< 0.001), respectively. CONCLUSIONS: In our experience, survival with ICIs was impaired in patients with lower AGR. Additionally, the AGR values could detect the very early progression and long-term benefit ICIs.

PURPOSE Immune checkpoint inhibitors (ICIs) have been demonstrated to improve overall survival (OS) in several tumor types. Durable responses have been reported with these agents in patients with melanoma and lung cancer. We aimed to quantify the proportion of patients who experience durable responses on ICIs and to compare it with other drug classes. PATIENTS AND METHODS We retrieved published phase III randomized trials that included at least one ICI arm in the recurrent and/or metastatic setting. A durable response to treatment was defined as a progression-free survival that exceeded three times the median progression-free survival of the whole population. The proportion of patients who experienced an OS that exceeded two times the median OS of the whole patient population also was estimated. RESULTS Nineteen studies involving 11,640 patients treated in 42 treatment arms (26 ICI and 16 non-ICI arms) were included. The mean proportion of patients who experienced a durable response was 2.3 times higher in those treated with an ICI compared with those treated in the control arms (25% v 11%). Durable responses were more frequent in patients treated with anti–PD-1/PD-L1 agents than in patients treated with anti–CTLA-4 agents (28% v 18%). The mean proportion of patients who had an OS that exceeded two times the median OS was also higher in those treated with ICIs than in those treated in the control arms (30% v 23%). In multivariable analysis, the effects of treatment with anti–PD-1/PD-L1 agents and of first-line treatment were statistically associated with a higher mean proportion of durable responses. CONCLUSION Durable responses were more frequent in patients treated with ICIs, although they also occurred in patients treated with other drug classes.

PURPOSE Immune checkpoint inhibitors (ICIs) are standard therapy in metastatic renal cell carcinoma (RCC). The safety and activity of the combination of ipilimumab and nivolumab in patients who have received prior ICI targeting the programmed death 1 (PD-1) pathway remains unknown. We evaluated ipilimumab and nivolumab in patients with metastatic RCC after prior treatment with anti–PD-1 pathway–targeted therapy. PATIENTS AND METHODS Patients with metastatic RCC who received prior anti–PD-1 pathway-targeted therapy and subsequently received ipilimumab and nivolumab were reviewed. Objective response rate and progression-free survival per investigator assessment were recorded. Toxicity of ipilimumab and nivolumab was also assessed. RESULTS Forty-five patients with metastatic RCC were included. All patients (100%) received prior ICIs targeting the PD-1 pathway. The median age was 62 years (range, 21-82 years). At a median follow-up of 12 months, the objective response rate to ipilimumab and nivolumab was 20%. The median progression-free survival while on ipilimumab and nivolumab was 4 months (range, 0.8-19 months). Immune-related adverse events (irAEs) of any grade with ipilimumab and nivolumab were recorded in 29 (64%) of the 45 patients; grade 3 irAEs were recorded in 6 (13%) of the 45 patients. CONCLUSION Ipilimumab and nivolumab demonstrated antitumor activity with acceptable toxicity in patients with metastatic RCC who had prior treatment with checkpoint inhibition.

The Impact

531 Background: The impact of corticosteroid treatment (CT) on the efficacy of immune checkpoint inhibitors (ICI) in hepatocellular carcinoma (HCC) is undefined. We evaluated whether CT administered at baseline (bCT) or concurrently to ICI (cCT) influences clinical outcomes of HCC patients treated with ICI. Methods: This retrospective, multi-center observational study was conducted across 9 tertiary academic referral centers collected 341 HCC patients who received ICI across 3 continents between January 1, 2016 and April 1, 2019. Outcome measures included overall (OS) and progression-free survival (PFS) calculated from time of ICI commencement and overall response rates (ORR) defined by Response Evaluation Criteria in Solid Tumors (v1.1) on 6-8 weekly periodic restaging. Results: Of 331 eligible patients, 254 (76%) had BCLC-C stage HCC and received mostly PD(L)-1 ICI monotherapy (n=250, 85%). Median OS was 12.1 months (95%CI 9.2-15.0 months) and median PFS was 8.1 months (95%CI 6.3-10 months). In total 81 patients (24%) received >10 mg prednisone equivalent daily either as bCT (n=15, 4%) or cCT (n=66, 20%). Indications for CT included procedure/prophylaxis (n=37, 45%), management of irAE (n=31, 37%), cancer-related symptoms (n=5, 2%) or comorbidities (n=8, 3%). Neither overall CT, bCT nor cCT predicted for worse OS, PFS nor ORR in uni- and multi-variable analyses (p>0.05). CT for cancer-related indications predicted for shorter PFS (2.4 vs. 11.3 months, p=0.01), OS (4.5 vs. 12.8 months, p=0.05) and reduced ORR (p=0.03) compared to cancer-unrelated indications. Conclusions: This is the first study to demonstrate that neither bCT nor cCT appear to influence response and OS following ICI in HCC. Worse survival and ORR in CT recipients for cancer-related indications appears driven by the poor prognosis associated with symptomatic HCC.
