Safety of Immune Checkpoint Inhibitors in Patients With Advanced Chronic Kidney Disease: A Retrospective Cohort Study.

ABSTRACT:

Background

Clinical trials of immune checkpoint inhibitors (ICIs) often do not include patients with advanced chronic kidney disease (CKD). We aimed to determine the safety of ICIs in patients with cancer and advanced CKD (stages 4-5 CKD, estimated glomerular filtration rate [eGFR] <30 mL/minute/1.73 m2).

Patients and methods

Patients with advanced CKD from the Mass General Brigham network who received ICIs (n = 91) were compared against those receiving nephrotoxic (n = 113) and non-nephrotoxic (n = 130) antineoplastic therapies, respectively. Rates of new-onset kidney failure (end-stage kidney disease or sustained eGFR ≤10 mL/minute/1.73 m2) and AKI were compared. Among ICI-treated patients, we modeled Fine-Gray subdistribution hazards to compare immune-related adverse event (irAE) risk and used Kaplan-Meier analysis to compare overall survival in patients with advanced CKD to those with eGFR ≥30 mL/minute/1.73 m2.

Results

Rates of new-onset kidney failure were similar at 1 year following initiation of ICIs (10.0%), nephrotoxic (6.2%), and non-nephrotoxic antineoplastic therapies (9.3%) (P = .28). AKI rates were also similar: 17.5%, 17.6%, and 20% of patients in each cohort, respectively (P = .87). Advanced CKD did not increase the risk of developing irAEs (adjusted hazard ratio [HR] 1.28, 95% CI, 0.91-1.81). However, patients with advanced CKD who received ICIs had a decreased overall survival compared with patients with eGFR ≥30 mL/minute/1.73 m2 (HR 1.30 for death, 95% CI, 1.02-1.66, P = .03).

Conclusion

ICIs are not associated with increased risk of AKI or new-onset kidney failure compared with other antineoplastic therapies in patients with advanced CKD. Advanced CKD did not increase the risk of extra-renal irAEs, although these patients suffered from lower overall survival.

Project description:BACKGROUND:Since 2012, several immune checkpoint inhibitors have been approved by the Taiwan FDA for various types of cancer treatment. However, none of them are covered by Taiwan National Health Insurance due to the fact that they are expensive, and there is a lack of clinical evidence as to their effectiveness. OBJECTIVES:This study was aimed toward an exploration of clinical experiences with use of immune checkpoint inhibitors, including indications, prescription types, drug effectiveness, adverse drug event types, and incidence, all of which shall serve as references for future clinical drug use. METHODS:This is a retrospective study focusing on three immune checkpoint inhibitors (ipilimumab, nivolumab, and pembrolizumab), which are available for cancer treatment in Taiwan. We collected data from medical records for the period from January 1st, 2015 to January 12th, 2017 at National Cheng Kung University Hospital (NCKUH), a medical center in southern Taiwan, and recorded these cases until May 31st, 2017. Overall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method, and adverse drug reaction odds ratios were analyzed using a chi-square analysis. RESULTS:The 50 patients under consideration in this study had used any one of the immune checkpoint inhibitors in NCKUH. Non-small cell lung cancer (n = 24, 48%) accounted for the highest percentage, followed by hepatocellular carcinoma (n = 4, 8%). The median OS was not reached, and the PFS for all immunotherapies was 4.9 months. The median OS period and PFS for non-small cell lung cancer (NSCLC) patients were 13 and 4.9 months, respectively, which were similar to those in many clinical trials. For NSCLC patients, the OS and PFS were only 0.63 and 1.37 months for squamous cell type NSCLC, and for patients who were PD-L1 negative, the OS and PFS were only 11.53 and 2.6 months, respectively. The most common adverse events in this study included fatigue (42%), rashes (22%), nausea (20%), and fever (20%), while one patient developed severe deep venous thrombosis and tissue inflammation, which was not confirmed in previous clinical trials. CONCLUSIONS:The histological subtype, the intensity of the PD-L1 expression, and the timing of treatment affected the NSCLC therapeutic results. It is recommended that clinical tests be conducted in order to enhance therapeutic effectiveness. It is expected that more testing, observation-based studies, and research results will validate their efficacy and the tolerance levels of patients.

Project description:BackgroundThe optimal timing to discontinue immune checkpoint inhibitor (ICI) therapy in hepatocellular carcinoma (HCC) patients with clinical benefits remains unclear. This study aimed to assess the outcomes of HCC patients after ICI discontinuation.MethodsPatients with HCC were retrospectively screened and those discontinued ICI therapy in the absence of progressive disease (PD) were included. Responses at discontinuation were evaluated per response evaluation criteria in solid tumors (RECIST) version 1.1 and modified RECIST (mRECIST). Patients were classified into five subgroups according to the cause of discontinuation: complete response (CR), partial response (PR), stable disease (SD) per RESICT version 1.1, adverse event (AE), or others. Progression-free survival (PFS) and overall survival (OS) since ICI start or after ICI discontinuation were assessed.ResultsA total of 66 patients were included. The median follow-up was 29.33 months. The median PFS since ICI start was 30.83 months [95% confidence interval (CI): 24.93-36.72], and the median OS was not reached. The median PFS after discontinuation was 20.6 months (95% CI: 7.63-33.56), and the median OS after discontinuation was not reached. Univariate analysis showed that age, treatment after discontinuation, Response (RECIST version 1.1) at discontinuation and modified response (mResponse per mRECIST) at discontinuation were significantly associated with PFS after discontinuation, while age and mResponse at discontinuation were significantly associated with OS after discontinuation. Multivariate analysis further demonstrated that mResponse at discontinuation and treatment after discontinuation were independently associated with PFS after discontinuation, while age was independently associated with OS after discontinuation.ConclusionsICIs might be discontinued in HCC patients with a response of CR per mRECIST. Patients with a response of PR/SD per mRECIST or elder age could continue ICI therapy after achieving clinical benefits. Tyrosine kinase inhibitor (TKI) maintenance therapy might help to prevent progression after ICI discontinuation.

Project description:BackgroundImmune checkpoint inhibitors (ICIs) have become one of the standard treatment options for advanced lung cancer. However, adverse events (AEs), particularly immune-related AEs (irAEs), caused by these drugs have aroused public attention. The current network meta-analysis (NMA) aimed to compare the risk of AEs across different ICI-based regimens in patients with advanced lung cancer.MethodsWe systematically searched the PubMed, EMBASE, and Cochrane Library databases (from inception to 19 April 2021) for relevant randomized controlled trials (RCTs) that compared two or more treatments, with at least one ICI administered to patients with advanced lung cancer. The primary outcomes were treatment-related AEs and irAEs, including grade 1-5 and grade 3-5. The secondary outcomes were grade 1-5 and grade 3-5 irAEs in specific organs. Both pairwise and network meta-analyses were conducted for chemotherapy, ICI monotherapy, ICI monotherapy + chemotherapy, dual ICIs therapy, and dual ICIs + chemotherapy for all safety outcomes. Node-splitting analyses were performed to test inconsistencies in network. Sensitivity analyses were adopted by restricting phase III RCTs and studies that enrolled patients with non-small cell lung cancer.ResultsOverall, 38 RCTs involving 22,178 patients with advanced lung cancer were enrolled. Both pooled incidence and NMA indicated that treatments containing chemotherapy increased the risk of treatment-related AEs when compared with ICI-based regimens without chemotherapy. As for grade 1-5 irAEs, dual ICIs + chemotherapy was associated with the highest risk of irAEs (probability in ranking first: 50.5%), followed by dual-ICI therapy (probability in ranking second: 47.2%), ICI monotherapy (probability in ranking third: 80.0%), ICI monotherapy + chemotherapy (probability in ranking fourth: 98.0%), and finally chemotherapy (probability in ranking fifth: 100.0%). In grade 3-5 irAEs, subtle differences were observed; when ranked from least safe to safest, the trend was dual ICIs therapy (60.4%), dual ICIs + chemotherapy (42.5%), ICI monotherapy (76.3%), ICI monotherapy + chemotherapy (95.0%), and chemotherapy (100.0%). Furthermore, detailed comparisons between ICI-based options provided irAE profiles based on specific organ/system and severity.ConclusionsIn consideration of overall immune-related safety profiles, ICI monotherapy + chemotherapy might be a better choice among ICI-based treatments for advanced lung cancer. The safety profiles of ICI-based treatments are various by specific irAEs and their severity.Systematic review registrationhttps://www.crd.york.ac.uk/prospero, identifier CRD42021268650.

Project description:BackgroundExtended interval dosing (ED) for inhibitors of programmed cell death protein 1 (anti-PD-1) (nivolumab, pembrolizumab) or its ligand (anti-PD-L1) (durvalumab) were recently approved based on pharmacokinetic model results that predicted a benefit-risk profile comparable with the standard dosing (SD) regimen. However, safety data in real-world condition of use are lacking. The objective was to compare the incidence and the risk factors of serious immune-related adverse events (irAEs) and any-grade irAEs between the SD and ED regimens in patients treated with anti-PD-1 or anti-PD-L1.Materials and methodsIrAEs were assessed from medical records in all new users of nivolumab, pembrolizumab, or durvalumab between 1 January 2019 and 31 December 2020 across two oncology centers in France. The incidence of irAEs was compared between both dosing regimens using Cox proportional hazards models adjusting for the main available confounders.ResultsAmong 686 patients included, 63% were new users of an SD regimen, 14% of ED regimen, and 23% started with SD and switched to ED regimen during follow-up. Overall, 34.6% of patients experienced at least one irAE of any grade and 11.4% presented at least one serious grade ≥3 irAE. No statistical difference was found between the SD and ED regimen on the risk of grade ≥3 irAEs [adjusted hazard ratio (HR) 1.40, 95% confidence interval (CI) 0.71-2.76] but our results suggest an increased risk of any-grade irAEs with the ED regimen (adjusted HR 1.46, 95% CI 1.00-2.12, P = 0.048). IrAEs resolved without sequelae in 46.4% of cases, and they were fatal for three patients (0.4%). Autoimmune pre-existing condition was confirmed as a risk factor for grade ≥3 irAEs (HR 2.56, 95% CI 1.53-4.27) and for all-grade irAEs (HR 1.60, 95% CI 1.17-2.20).ConclusionsIn a real-world setting, according to the regimen chosen by the oncologist based on clinical characteristics, we did not observe an increase in grade ≥3 irAE incidence between the SD and ED regimens.
