e15087 Background: Programmed death 1 (PD-1) inhibitors and Programmed Death-Ligand 1 (PD-L1) inhibitors are immune checkpoint inhibitors (ICIs) approved for treatment of several different cancers. Colitis is a major immune-related adverse event associated with ICIs, but the risk of colitis with PD-1 versus PD-L1 inhibitors is not well characterized. Methods: We performed a meta-analysis for the incidence of all grade and grade 3-4 colitis with PD-1 inhibitor (nivolumab, pembrolizumab, and cemiplimab) or PD-L1 inhibitor (atezolizumab, avelumab, and durvalumab) monotherapy using a fixed effects model. We also conducted subgroup meta-analyses of non-small cell lung cancer (NSCLC) or urothelial carcinoma (UC) trials, and a network meta-analysis of randomized trials comparing PD-1 or PD-L1 inhibitors with docetaxel for NSCLC. We analyzed Food and Drug Administration Adverse Event Reporting System (FAERS) database to estimate the reporting odds ratio (ROR) of each medication, which provides the estimated relative risk most valid in spontaneous report database. Results: We identified 88 studies that met inclusion for the analysis. PD-1 inhibitors were associated with higher incidence of all grade and grade 3-4 colitis compared to PD-L1 inhibitors in the analysis of all cancer types (1.49% vs 0.83%, relative risk (RR); 1.80, 95% confidence interval (CI); 1.22-2.67 for all grade colitis, and 0.85% vs 0.34%, RR; 2.52, 95% CI; 1.46-4.37 for grade 3-4 colitis). The meta-analyses on NSCLC and UC, and the network meta-analysis on NSCLC also showed the tendency that PD-1 inhibitors are associated with higher risk of all grade and grade 3-4 colitis, though only the analysis on UC for all grade colitis showed a significant difference. (1.95% vs 0.64%, RR; 3.05, 95% CI; 1.18 - 7.88) Retrospective analysis showed ROR of 16.78 (95% CI; 15.8-17.8) for PD-1 inhibitors, and 12.93 (95% CI; 10.74-15.42) for PD-L1 inhibitors. We found that ROR of PD-1inhibitors was 1.17 (95% CI; 0.97-1.43) compared to PD-L1 inhibitors. Conclusions: Our study showed that PD-1 inhibitors have higher risk of colitis than PD-L1 inhibitors.

Programmed Death 1

Kidney injury associated with use of immune checkpoint inhibitors that target the programmed death-1 molecule commonly manifests as acute tubulointerstitial nephritis on kidney biopsy. We present a case of a 66-year-old man who developed acute kidney injury at 6 months after initiation of treatment with anti-programmed death-1 antibody, nivolumab, for treatment of metastatic urothelial carcinoma. A renal biopsy showed focal moderate-to-severe lymphocytic tubulitis with minimal interstitial inflammation. Programmed death ligand-1 immunopositivity was detected only in tubules exhibiting lymphocytic tubulitis. The patient’s renal function improved to baseline with conservative management consisting of discontinuation of nivolumab followed by prednisone treatment.

Abstract Background Radiotherapy may synergize with programmed death 1 (PD-1)/PD-1 ligand (PD-L1) blockade. The purpose of this study was to determine the recommended Phase II dose, safety/tolerability, and preliminary efficacy of combining pembrolizumab, an anti-PD-1 monoclonal antibody, with hypofractionated stereotactic irradiation (HFSRT) and bevacizumab in patients with recurrent high grade gliomas (HGGs). Methods Eligible subjects with recurrent glioblastoma or anaplastic astrocytoma were treated with pembrolizumab (100 or 200 mg based on dose level Q3W) concurrently with HFSRT (30 Gy in 5 fractions) and bevacizumab 10 mg/kg Q2W. Results Thirty two patients were enrolled (bevacizumab naïve, n = 24; bevacizumab resistant, n = 8). The most common treatment-related adverse events (TRAEs) were proteinuria (40.6%), fatigue (25%), increased alanine aminotransferase (25%), and hypertension (25%). TRAEs leading to discontinuation occurred in 1 patient who experienced a grade 3 elevation of aspartate aminotransferase. In the bevacizumab naïve cohort, twenty patients (83%) had a complete response (CR) or partial response (PR). The median overall survival (OS) and progression-free survival (PFS) were 13.45 months (95% CI: 9.46-18.46) and 7.92 months (95% CI: 6.31-12.45), respectively. In the bevacizumab resistant cohort, PR was achieved in 5 patients (62%). Median OS was 9.3 months (95% CI: 8.97-18.86) with a median PFS of 6.54 months (95% CI: 5.95-18.86). The majority of patients (20/26 pts; 77%) had tumor-cell/tumor-microenvironment PD-L1 expression <1%. Conclusions The combination of HFSRT with pembrolizumab and bevacizumab in patients with recurrent HGG is generally safe and well tolerated. These findings merit further investigation of HFSRT with immunotherapy in HGGs.

Purpose The addition of nivolumab (anti–programmed death-1 antibody) to ipilimumab (anti–cytotoxic T-cell lymphocyte–associated 4 antibody) in patients with advanced melanoma improves antitumor response and progression-free survival but with a higher frequency of adverse events (AEs). This cross-melanoma study describes the safety profile of the approved nivolumab plus ipilimumab regimen. Methods This retrospective safety review on data from three trials (phase I, II, and III) included patients with advanced melanoma who received at least one dose of nivolumab 1 mg/kg plus ipilimumab 3 mg/kg every 3 weeks × 4 and then nivolumab 3 mg/kg every 2 weeks until disease progression or unacceptable toxicity while following established guidelines for AE management. Analyses were of all treatment-related AEs, select (immune-related) AEs, time to onset and resolution, and use of immune-modulating agents and their effects on outcome. Results Among 448 patients, median duration of follow-up was 13.2 months. Treatment-related grade 3/4 AEs occurred in 55.5% of patients; 35.7% had treatment-related AEs that led to discontinuation. The most frequent treatment-related select AEs of any grade were skin (64.3%) and GI (46.7%) and of grade 3/4, hepatic (17.0%) and GI (16.3%); 30.1% developed a grade 2 to 4 select AE in more than one organ category. Median time to onset of grade 3/4 treatment-related select AEs ranged from 3.1 (skin) to 16.3 (renal) weeks, and with the exclusion of endocrine AEs, median time to resolution from onset ranged from 1.9 (renal) to 4.5 (pulmonary) weeks, with resolution rates between 79% and 100% while using immune-modulating agents. Four (< 1%) on-study deaths were attributed to therapy. Conclusion Frequency of grade 3/4 treatment-related AEs was higher with nivolumab plus ipilimumab and occurred earlier than historical experience with either agent alone, but resolution rates were similar.
