A Network Comparison on Safety Profiling of Immune Checkpoint Inhibitors in Advanced Lung Cancer

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

BackgroundImmune checkpoint inhibitors (ICI) are standard treatment for stage III/IV non-small cell lung cancer (NSCLC). ICIs may cause immune-related adverse events (irAEs) often requiring corticosteroids or other immunosuppressive therapy and are associated with increased risk of opportunistic infections.1 2 The burden of infectious complications in NSCLC patients (pts) treated with ICIs is poorly described.MethodsWe retrospectively reviewed NSCLC pts treated with ICIs between 2016–2020 at a large tertiary academic center. An infectious complication related to ICIs was defined as a pathogen-confirmed or clinically diagnosed infection requiring antimicrobials during or within 3 months of ICI discontinuation. High-grade infections were defined as those requiring IV antibiotics (grade 3), life-threatening or requiring ICU stay (grade 4), or resulting in death (grade 5). irAEs were defined by the treating provider and treated according to standard guidelines. Patient demographics, treatment data, cancer outcomes, infectious complications, and irAE details were annotated in an IRB-approved database. An AE treated as both an infection and/or irAE with antibiotics and immunosuppression was coded as a concomitant irAE/infection event. The association between patient features and infectious complications was examined using logistic regression. Treatment and disease characteristics for concomitant irAE with infection were also described.Results302 ICI-treated NSCLC pts were included. 211 pts received PD-1 monotherapy and 91 received PD-1 therapy with CTLA-4 therapy, chemotherapy, or other investigational therapy. The majority (175/302, 57.9%) had a documented infection (bacterial=138, viral=17, fungal=19, mycobacterial=1) during or within 3 months of ICI discontinuation. Grade ≥3 infections occurred in 33.4% of pts (101/302). Pulmonary infections were most common (35.4%), followed by gastrointestinal, urinary, and skin (<10%, each). A subset of pts were treated as having concomitant irAE/infection events (63/302, 20.9%). Among 63 pts who experienced irAEs, pneumonitis occurred most commonly (47/63, 74.6%) followed by colitis (7/63, 11.1%); other irAEs (hepatitis, myocarditis, thyroiditis) occurred in <3 patients each. A concomitant event was associated with a trend toward higher odds of hospitalization (OR 3.91, CI 0.5–30.76) when adjusted for grade ≥3 infection. Similarly, steroid use within one month prior to infection, was also associated with a trend toward higher odds of hospitalization (OR 8.88, CI 0.81–97.15), adjusted for grade ≥3 infection.ConclusionsIn this retrospective study of NSCLC pts treated with ICIs, the majority experienced infections during or within 3 months of ICI discontinuation. The most common infections were bacterial pulmonary in origin. Concomitant irAE/infection was associated with trend toward higher odds of hospitalization.ReferencesHamashima R, Uchino J, Morimoto Y, et al.

Objectives. Immune checkpoint inhibitors (ICI) combined with radiotherapy (RT) have emerged as a breakthrough therapy in the treatment of various cancers. The combination has a strong rationale, but data on their efficacy and safety are still limited. Hence, we comprehensively searched the database and performed this study to elucidate the clinical manifestations of this combined strategy. Methods. We performed a meta-analysis of randomized trials that compared ICI plus RT with placebo plus RT or ICI alone for the treatment of advanced nonsmall-cell lung cancer (NSCLC) and prostate cancer. The outcomes included overall survival (OS), progression-free survival (PFS), disease control rate (DCR), and treatment-related adverse events. A fixed-effects or random-effects model was adopted depending on between-study heterogeneity. Results. Three trials involving 1584 patients were included. ICI plus RT was significantly associated with improvement of OS (hazard ratio [HR] = 0.81, 95% confidence interval [CI] = 0.70–0.94, P = 0.004 ), PFS (HR = 0.64; 95% CI 0.56–0.72, P < 0.00001 ), and DCR (relative risk [RR] = 1.38; 95% CI 1.03–1.84, P = 0.03 ). A significant predictor for PFS with the combination of ICI and RT was age, as a significant improvement in PFS (HR = 0.49; 95% CI 0.37–0.64, P < 0.00001 ) was observed in NSCLC patients aged under 65 years. In safety analyses, patients receiving ICI plus RT had a significantly higher incidence of dyspnea (RR = 2.43; 95% CI 1.16–5.08, P = 0.02 ) and pneumonitis of grade 3 or higher (RR = 2.78; 95% CI 1.32–5.85, P = 0.007 ). Conclusion. The combination of ICI and RT was associated with improved OS, PFS, and DCR. Patients under 65 years will be the dominant beneficiaries. However, the incidence of dyspnea and pneumonia of grade 3 or higher also increased, which deserves our vigilance.

Abstract Background: Immune checkpoint inhibitors (ICIs) emerged as the preferred therapy in advanced lung cancer, understanding the treatment- and immune-related adverse events of these drugs is of great significance for clinical practice. Materials and methods: PubMed, Embase, Cochrane library and major conference proceedings were systematically searched for all randomized controlled trials (RCTs) in lung cancer using PD-1/PD-L1/CTLA-4 inhibitors. The outcomes included treatment-related adverse events (TRAEs) and several organ specific immune-related adverse events (IRAEs). Results: 24 RCTs involving 14,256 patients were included. There was a significant difference for ICI therapy in the incidence of any grade of TRAEs (RR: 0.90; 95%CI: 0.84–0.95; P=0.001) and a lower frequency of grade 3-5 of TRAEs (RR: 0.65; 95%CI: 0.51–0.82; P<0.001). Patients treated with ICI therapy in non–small-cell lung cancer (NSCLC) were less reported TRAEs than in small cell lung cancer (SCLC). A lower risk of TRAEs was favored by anti-PD-1 inhibitors over anti-PD-L1 antibodies and anti-CTLA-4 drugs. The most common organ specific IRAE was hypothyroidism that occurred 8.7%. The incidence of pneumonitis and hepatitis reached 4.5% and 4.0% respectively. Compared with patients treated in control arms, those treated with ICI drugs were at higher risk for each organ specific adverse event including colitis, hepatitis, pneumonitis, hypothyroidism and hypophysitis. Conclusions: ICI therapy was safer than chemotherapy, especially ICI monotherapy such as anti-PD-1 antibodies in NSCLC. Compared with standard treatments, ICI drugs increased the risk of organ-specific IRAEs, although the overall incidence remained low.
