RESUMO
OBJECTIVES: Immune checkpoint inhibitors (ICIs) targeting cytotoxic T-lymphocyte-associated protein 4 and programmed cell death protein 1 (PD-1) have demonstrated improved survival for multiple cancers. However, these new drug classes have led to increased immune-related adverse events (IrAE). Rheumatic IrAEs have not been well described in clinical trials. We report here cases of rheumatoid arthritis (RA) and polymyalgia rheumatica (PMR) occurring after ICI treatment. METHODS: This was a retrospective study of patients receiving an ICI in whom symptoms of arthritis or arthralgia developed and revealed a diagnosis of RA or PMR. RESULTS: In 10 patients who received ICI therapy (all anti-PD-1 or anti-PDL1 antibodies), RA or PMR developed at a median of 1 month (1 to 9) after exposure. No patient had pre-existing rheumatic or autoimmune disease. RA developed in six patients; all six were positive for anti-cyclic citrullinated peptide (anti-CCP) antibodies and four for rheumatoid factor. Anti-CCP antibodies were detected in two out of three patients tested before immunotherapy. Disease-modifying antirheumatic drugs were needed for three patients; the three others received corticosteroids or non-steroid anti-inflammatory drugs. PMR was diagnosed in four patients, all responded to corticosteroids. Despite these IrAEs, immunotherapy was pursued for all but one patient until cancer progression. CONCLUSIONS: This is the first description of RA occurring after ICI therapy for cancer. PMR can also occur after ICI, particularly after anti-PD-1 therapy. All cases responded to corticosteroids or with immunosuppressive therapy. Collaboration between rheumatologists and oncologists is crucial and could lead to better recognition and care of these patients.

INTRODUCTION: Association of high body mass index (BMI) with longer survival has been reported in patients on immune checkpoint inhibitors (ICIs), but results are inconsistent. This 'obesity paradox' is potentially confounded by the effects of BMI change over time and of skeletal muscle depletion. METHODS: We conducted a secondary analysis of a prospective cohort, including consecutive patients receiving ICI treatment for melanoma (n = 411) and non-small cell lung cancer (NSCLC) (n = 389) in routine care. RESULTS: In the univariable analysis of the entire population, overweight/obesity (BMI ≥ 25 kg/m2) was associated with longer survival (p < 0.01); however, this effect was limited to NSCLC (p < 0.01) and was absent in melanoma. Weight loss (WL) and reduced skeletal muscle mass were observed in patients within all BMI categories. WL was associated with shorter survival in multivariable analysis in both tumour sites (p < 0.01), and for NSCLC, BMI lost significance when WL was included (p = 0.13). In models further adjusted for CT-defined skeletal muscle mass, WL retained significance for both tumour types (p < 0.01), and reduced skeletal muscle only for NSCLC (p = 0.02) was associated with shorter survival. WL retained significance when biomarkers (lactate dehydrogenase enzyme, albumin and derived neutrophil to lymphocyte ratio) were added to the multivariable model. CONCLUSIONS: The so-called 'obesity paradox', counterintuitive association between high BMI and longer survival, vanished when controlling for confounders, such as type of cancer, and manifestations of depletion (WL and reduced skeletal muscle mass).

BACKGROUND: Numerous retrospective studies and reviews have reported a positive association between immune-related adverse events (irAEs) and survival in non-small cell lung cancer (NSCLC) and melanoma patients treated with immune checkpoint blockers (ICBs). However, some results are controversial and the studies, whose results converge, should be interpreted cautiously because most of them do not deal appropriately with the immortal-time bias. Here, we report an observational real-life study of the association between prospectively collected irAEs and survival of patients treated with ICBs while dealing with the immortal-time bias. METHODS: Data from patients treated at Gustave Roussy from June 2014 to October 2017 with anti-PD-(L)1 antibodies for a melanoma or NSCLC have been prospectively collected in the REISAMIC database, a pharmacovigilance registry dedicated to irAEs. Adverse events of grade 2 and higher were collected prospectively. To study the association between the occurrence of irAEs and survival, we used both a landmark analysis and a Cox regression model with time-dependent covariate. RESULTS: 577 patients were treated with anti-PD-(L)1 antibodies for melanoma (60.3 %) or NSCLC (39.7 %). The occurrence of an irAE was significantly associated with improved overall survival (OS): HR 0.56, 95 % CI [0.41; 0.75], p = 0.0001 and progression-free survival (PFS): HR 0.63, 95 % CI [0.47; 0.83], p = 0.001 using a Cox regression model with time-dependent covariate. In a 12-week landmark analysis, median OS was 21.2 months (95 % CI, 12.2 to 35.7) and 16.4 months (95 % CI, 12.4 to 21.3) p = 0.26 and median PFS was 14.3 months (95 % CI, 9.5 to 24.6) and 13.4 months (95 % CI, 10.2 to 18.3) p = 0.66, for patients with and without irAEs, respectively. CONCLUSIONS: In our real-life study of patients with melanoma and NSCLC treated with anti-PD-(L)1 antibodies, we confirm that irAEs are associated with improved survival using a time-varying Cox regression model. Analysis with a landmark method showed no difference in OS or PFS between patients who experienced irAE during the first 12 weeks of treatment and those who did not. Retrospective analysis and reviews including studies that do not deal with the immortal-time bias and studies insufficiently powered for a landmark analysis should be interpreted with caution.

BACKGROUND: Immune-related adverse events (irAEs) remain generally unpredictable, and severe irAEs remain challenging to detect early and manage. Very severe (grade IV-V) irAEs have not been extensively characterised in prospective studies, and their predictive factors remain unknown. OBJECTIVE: The objective of the study was to describe and identify predictive factors of very severe (grade IV-V) irAEs. DESIGN: The French Registre des Effets Indésirables Sévères des Anticorps Monoclonaux Immunomodulateurs en Cancérologie (REISAMIC) registry has prospectively collected all clinically significant irAEs occurring in patients treated with immune checkpoint inhibitors at Gustave Roussy Institute since 2014. SETTING: This was a single-centre prospective cohort study at the Gustave Roussy Institute cancer centre (Villejuif, France). PARTICIPANTS: The participants were all adult patients with a solid or haematological cancer treated with an anti-programmed cell death 1 (PD-1) or an anti-programmed cell death-ligand 1 (PD-L1) and who presented a clinically significant irAE. MAIN OUTCOMES AND MEASURES: The main outcomes included the clinical and laboratory characteristics of patients with very severe irAEs, including tumour type, affected organs, time to irAE occurrence, blood cell count and serum biochemistry parameters. RESULTS: Of the 1187 patients prospectively followed in REISAMIC between December 2014 and January 2020, 380 (32.0%) had at least one irAE, and 34 (2.86%) presented with very severe irAEs (grades IV-V). Among the 380 patients with an irAE, the distribution of very severe irAEs (grades IV-V) was 8.95% and death (grade V) was 3.95%. Among the 34 patients with very severe irAEs, 33 were treated with monotherapy of PD-1 or PD-L1 inhibitors, and one patient was treated with a combination of PD-1 and cytotoxic T-lymphocyte-associated protein 4 inhibitors. The median time to occurrence was shorter for very severe irAEs (median [interquartile range]: 41 days [0-634] for grades IV-V; versus 91 days [0-1123] for grades I-III; p = 0.01680). On initiation of immunotherapy, the predictive factors for very severe irAEs were performance status ≥2, elevated neutrophil/lymphocyte ratio and treatment for lung cancer. CONCLUSIONS: Very severe (grade IV-V) immunological toxicities occurred earlier than mild severe toxicities. On initiation of immunotherapy, patients with poor performance status, elevated neutrophil/lymphocyte ratio and lung cancer are identified at risk of developing these very severe toxicities. These results could help to develop risk scores to identify patients at risk of developing severe toxicities.

OBJECTIVE: To analyse the clinical patterns of sarcoidosis triggered by immune checkpoint inhibitors (ICIs) in patients with cancer. PATIENTS AND METHODS: The ImmunoCancer International Registry is a big data-sharing multidisciplinary network from 18 countries dedicated to evaluating the clinical research of immune-related adverse events related to cancer immunotherapies. RESULTS: We identified 32 patients with biopsy-proven sarcoidosis. Underlying cancer included mainly melanoma (n = 24). Cancer immunotherapy consisted of monotherapy in 19 cases (anti-PD-1 in 18 and ipilimumab in 1) or combined ipilimumab + nivolumab in 13. The time median interval between initiation of ICI and sarcoidosis diagnosis was 3 months (range, 2-29 months). The use of combined ICI was associated with a shorter delay in developing sarcoidosis symptoms. The disease was symptomatic in 19 (59%) cases with mostly cutaneous, respiratory and general symptoms. The organs involved included mainly the mediastinal lymph nodes (n = 32), the lungs (n = 11), the skin (n = 10) and the eyes (n = 5). Pulmonary computed tomography studies showed bilateral hilar lymphadenopathy in all cases. There was no severe manifestation. Specific systemic therapy was required in only 12 patients (37%): oral glucocorticoids in 9, and hydroxychloroquine in 3. ICIs were held in 25 patients (78%) and definitively discontinued in 18 (56%) patients. Seven patients continued ICI treatment with a second flare in one case. In six additional patients, an ICI was reintroduced with no harm, and sarcoidosis relapsed in one of them. CONCLUSION: Our study shows that ICI-related sarcoidosis seems to have a specific profile, possibly more benign than that of idiopathic sarcoidosis, and does not necessarily imply ICI discontinuation.

Neurological immune-related adverse events are complications of programmed-cell death 1 or programmed-cell death 1 ligand immunotherapies that can be life threatening and often lead to anticancer immunotherapy withdrawal. Scant clinical data are available that integrate the clinical presentation, therapeutic management and long-term outcome. All consecutive adult patients treated by programmed-cell death 1 or programmed-cell death 1 ligand immunotherapies, given alone or in combination with other treatment, who experienced a neurological immune-related adverse event with a severity grade ≥2 in Paris Saclay-University hospitals were investigated from June 2014 to February 2019. The frequency of neurological immune-related adverse events was calculated from the prospective Registre des Effets Indésirables Sévères des Anticorps Monoclonaux Immunomodulateurs en Cancérologie cohort. Forty patients presenting with 51 distinct neurological immune-related adverse events were included. The prevalence of grade ≥2 neurological immune-related adverse events was estimated to be 1.22% in the Registre des Effets Indésirables Sévères des Anticorps Monoclonaux Immunomodulateurs en Cancérologie cohort. Among 40 patients with neurological immune-related adverse events, 65% received programmed-cell death 1 or programmed-cell death 1 ligand monotherapy and 35% received a combination of programmed-cell death 1 plus anti-CTLA4 (Common Terminology Criteria for Adverse Events). Clinical neurological presentations were peripheral (48%), central (35%), or mixed (18%). The severity of neurological immune-related adverse events was grade 2 for 14 (35%) and ≥grade 3 for 26 patients (65%). The mortality rate related to neurological immune-related adverse events was 8%. Corticosteroid treatment led to neurological recovery in 74%. Long-term follow-up highlighted that 53% of patients experienced long-term neurological sequelae. Five patients were rechallenged by programmed-cell death 1 monotherapy without recurrence of their neurological immune-related adverse event(s). Neurological immune-related adverse events induced by programmed-cell death 1 or programmed-cell death 1 ligand are rare but are severe with a mortality rate of 8% and long-term sequelae for 53% of patients. Corticosteroids should be started when neurological immunological complications are identified to avoid long-term sequelae.
RESUMO
PURPOSE: CD28, CD57, and KLRG1 have been previously identified as markers of T-cell immunosenescence. The impact of immunosenescence on anti-PD(L)-1 (ICI) or platinum-based chemotherapy (PCT) in patients with advanced non-small cell lung cancer (aNSCLC) is unknown. EXPERIMENTAL DESIGN: The percentage of CD28-, CD57+, KLRG1+ among CD8+ T cells [senescent immune phenotype (SIP)] was assessed by flow cytometry on blood from patients with aNSCLC before single-agent ICI (discovery cohort). A SIP cut-off was identified by log-rank maximization method and patients with aNSCLC treated with ICI (validation cohort) or PCT were classified accordingly. Proliferation and functional properties of SIP+ CD8+ T cells were assessed in vitro. RESULTS: In the ICI discovery cohort (N = 37), SIP cut-off was 39.5%, 27% of patients were SIP+. In the ICI validation cohort (N = 46), SIP+ status was found in 28% of patients and significantly correlated with worse objective response rate (ORR; 0% vs. 30%, P = 0.04), median progression-free survival (PFS) [1.8 (95% confidence interval (CI), 1.3-NR) vs. 6.4 (95% CI, 2-19) months, P = 0.009] and median overall survival, OS [2.8 (95% CI, 2.0-NR) vs. 20.8 (95% CI, 6.0-NR) months, P = 0.02]. SIP+ status was significantly associated with circulating specific immunephenotypes, in vitro lower CD8+ T cells proliferation, lower IL2 and higher TNFα and IFNγ production. In the ICI-pooled population (N = 83), SIP+ status did not correlate with any clinical characteristics and it was associated with significantly worse ORR, PFS, and OS. In PCT cohort (N = 61), 11% of patients were SIP+. SIP status did not correlate with outcomes upon PCT. CONCLUSIONS: Circulating T-cell immunosenescence is observed in up to 28% of patients with aNSCLC and correlates with lack of benefit from ICI but not from PCT.See related commentary by Salas-Benito et al., p. 374.

PURPOSE: Sarcoid-like granulomatosis (SLG) reaction caused by immunotherapy remains poorly understood. This study aims to investigate the outcome of patients with cancer and SLG associated with immunotherapy. PATIENTS AND METHODS: Between April 2016 and June 2020, 434 patients with immunological adverse events were screened from the ImmunoTOX assessment board of Gustave Roussy, an academic cancer centre in France. Among them, 28 patients had SLG associated with immunotherapy (SLG cohort) and 406 patients had other immunological adverse events (control cohort). Clinical characteristics and outcome of patients were compared from SLG and control cohort. RESULTS: The SLG cohort consisted of 28 patients, 14 women and 14 men, with the median (range) age of 56.5 (28.7-75.3) years. Patients in the SLG cohort with sarcoidosis were asymptomatic (only radiographical finding) in 13 (46.4%) cases; otherwise, the most frequent symptoms were dyspnoea in 8 (28.6%) patients and cough in 5 (17.8%) patients. The computerised tomography scan found sarcoidosis localisations in mediastinal or peri-hilar thoracic lymph nodes in 26 (92.9%) patients, and lung parenchymal involvement was found in 14 (50.0%) patients. The radiographic Scadding stages for sarcoidosis classification were distributed in stages 0, I, II, III and IV in 2 patients (7.1%), 13 patients (46.4%), 11 patients (39.3%), 1 patient (3.6%) and 1 patient (3.6%), respectively. Compared with patients with other immunological toxicities (cohort control), patients with sarcoidosis presented most frequently with melanoma (75.0% versus 21.9% of patients; p < 0.001) and more often received combined therapies of anti-programmed cell death 1 plus anti-cytotoxic T-lymphocyte antigen 4 protein (46.4% versus 12.6% of patients; p = 0.002). Patients with sarcoidosis had an improved overall survival (OS); the median OS was not reached in the SLG cohort and 40.4 months in the control cohort, hazard ratio = 0.232 (95% confidence interval: 0.086-0.630) (p = 0.002). CONCLUSION: Sarcoidosis-like reactions in patients receiving immunotherapy were reported as non-severe immunological reactions in most cases and were correlated with improved OS. SLG should not be misdiagnosed as tumour progression in patients receiving immunotherapy treatment for cancer.

BACKGROUND: The use of immune checkpoint inhibitors (ICI) in melanoma and non-small cell lung cancer patients is associated with the onset of vitiligo. However, previous studies have suggested conflicting results on the conditions of occurrence of ICI-induced vitiligo. OBJECTIVE: The aim of this study was to describe the occurrences and outcomes of several cases of ICI-induced vitiligo. METHODS: A retrospective study was carried out using the French Pharmacovigilance Database (FPD) between the beginning of the commercialization of ICI in France and 1 January 2019, selecting for analysis the vitiligo reactions of patients due to treatment with ICI. RESULTS: Among the 95 case patients identified in the FPD, the median times to onset of vitiligo after the start of pembrolizumab, nivolumab and ipilimumab therapies were 5.4, 5.0, and 3.8 months, respectively. Furthermore, 37 patients (45%) discontinued ICI treatment due to disease progression. The median follow-up time of all patients was 33 months (interquartile range 2-56). CONCLUSIONS: This study provided an overall picture of ICI-induced vitiligo in daily medical practice on a large number of pharmacovigilance observations of case patients. Among the observations of ICI-induced vitiligo, the diagnosed cancer was melanoma for almost all patients. Most patients in the study experienced other associated adverse drug reactions (ADRs), such as colitis, pruritus, hypothyroidism, hyperthyroidism, thyroiditis, pancreatitis, and gastritis. Furthermore, our data suggest that the resolution of pembrolizumab- or nivolumab-induced vitiligo could be a marker of disease progression. Future studies evaluating vitiligo outcomes are warranted.

OBJECTIVE: Immune checkpoint inhibitor (ICI) antibodies constitute a new generation of cancer treatments, associated with immune-related adverse events (irAEs). A previous retrospective study of patients with metastatic melanoma (treated mostly with anti-CTLA4 antibodies) reported a serious infection rate of 7.3%. The main risk factors were corticoids and infliximab use. We sought to describe infections and risk factors among patients receiving anti-PD-1/PD-L1 ICIs. PATIENTS AND METHODS: We reviewed 200 medical records sampled randomly from a French prospective registry, which collates patients treated with anti-PD-1/PD-L1 ICIs. We recorded demographic data, the occurrence of irAEs, immunosuppressant use, and the outcome. RESULTS: Thirty-six patients (18%) experienced an infection by a median (interquartile range) of 47 (19.2-132) days after initiation of the ICI. Twenty-one patients (58.3%) had a lung infection, seven (19.4%) had a skin infection, seven (19.4%) had a urinary tract infection, and all of them received antibiotics. The infection was generally mild, and the patients were treated as outpatient. There were no infection-related deaths and no opportunistic infection. Sixty percent of the patients were being treated for metastatic melanoma and 35.5% for non-small cell lung cancer, and 106 irAEs (mostly grade II) were reported. Forty-seven patients received steroids for cancer symptoms or irAEs, and five received immunosuppressants during the immunotherapy. We did not observe any association between corticosteroid or immunosuppressant use and the occurrence of an infection. CONCLUSION: The infection rate in patients treated with an anti-PD-1/PD-L1 ICI was 18%, without any severe or opportunistic infection. The occurrence of an infection was not associated with corticosteroid or immunosuppressant use.

BACKGROUND: Aging is an important risk factor for cancers and is associated with poor prognosis. Weakness of the immune system, also called immunosenescence may occur with older age. The impact of aging on efficacy and safety of immune checkpoint blockers, such as anti-programmed death (ligand) PD-(L)1, remains undetermined. This study aims to evaluate the incidence of immune-related adverse events (irAEs) in patients aged 70 years or older than their younger counterparts. METHODS: Patients with advanced solid tumors treated at Gustave Roussy with an anti-PD-(L)1 monotherapy between June 2014 and October 2017 were prospectively included within the dedicated irAEs pharmacovigilance registry REISAMIC (Registre des Effets Indésirables Sévères des Anticorps Monoclonaux Immunomodulateurs en Cancérologie). The incidence of irAEs of grade ≥II was compared between patients aged ≥70 (old patients, OP) versus patients aged < 70 years (young patients, YP) using a chi-squared test. Survivals were estimated using the Kaplan-Meier method. RESULTS: Among the 603 patients treated by anti-PD(L)1, 191 were ≥70 y.o (OP) and 424 < 70 y.o (YP). The median (range) age of OP and YP were respectively 77 (70-93) and 59 years old (17-69). A total of 165 irAEs occurred in these patients (103 grade II and 58 grade III-IV). The overall incidence of grade ≥II irAEs was higher in OP than in YP (33% versus 25%, p = 0.03). In addition, OP were more prone of having multiples irAEs compared with YP (p = 0.037). Skin toxicities were more frequent in OP than in YP (p = 0.007) but endocrine toxicities were less frequent in OP than in YP (p = 0.044). This higher level of irAEs seems to be responsible for a higher rate of treatment discontinuation in OP (p = 0.2). There was no statistical difference in median time to toxicity, exposure to steroids or survival between the two groups. CONCLUSION: Although anti-PD-(L)1 immunotherapies remain an acceptable treatment option for older patients, prescribers should be aware that irAEs are more frequent in the elderly. Further translational studies are warranted to better understand the relationship between aging and irAEs.

PURPOSE: We investigated the activities of an ImmunoTOX board, an academic, multidisciplinary group of oncologists and organ specialists that adopts a real-life, case-by-case approach in the management of patients with immune-related adverse events (irAEs). EXPERIMENTAL DESIGN: The ImmunoTOX assessment board was set up in 2016 at Gustave Roussy in France. It meets every 2 weeks to discuss the case-by-case management of patients presenting with irAEs. Here, we describe the ImmunoTOX board's activities between 2016 and 2019. RESULTS: Over study period, 398 requests (concerning 356 patients) were submitted to the ImmunoTOX board. Most of the requests concerned the putative causal link between immunotherapy and the irAE (n = 148, 37%), followed by possible retreatment after temporary withdrawal because of an adverse event (n = 109, 27%), the clinical management of complex situations (n = 100, 25%) and the initiation of immunotherapy in patients with pre-existing comorbidities (n = 41, 10%). The ImmunoTOX board discerned 273 irAEs. The five organ systems most frequently involved by irAEs were lung (n = 58, 21%), gastrointestinal tract (n = 36, 13%), liver or biliary tract (n = 33, 12%), musculoskeletal system (n = 27, 10%), and nervous system (n = 23, 8%). The time to occurrence was shorter for severe irAEs (grade III and VI) than for mild irAEs (grades I and II), with medians of 47 and 91 days, respectively (p = 0.0216). CONCLUSION: The main medical needs in the management of irAEs involved the lung organ. Severe irAEs were expected to occur earlier than mild irAEs. This real-life study can help to better estimate medical needs and therefore help to assess the management of irAEs.

PURPOSE: Immune checkpoint inhibitors (ICI) targeting the programmed cell death protein 1 (PD-1), or its ligand PD-L1, are the mainstay of metastatic cancer treatment. Patients receiving these treatments may develop immune-related adverse events (irAEs). This study aimed to estimate the prevalence and describe the clinical patterns of moderate-to-severe ocular irAEs-associated with anti-PD-(L)1 treatment. DESIGN: Prospective case series. METHODS: This study included patients recruited via (1) a single-center prospective cohort and (2) a national pharmacovigilance registry between June 2014 and March 2018, and focused on patients with moderate-to-severe ocular irAEs following anti-PD-(L)1. All patients underwent a comprehensive ophthalmologic assessment. The main outcome measure was the prevalence of moderate-to-severe ocular irAEs. RESULTS: Of a total of 745 patients included in the prospective cohort, 3 developed moderate-to-severe ocular irAEs, providing a prevalence of 0.4% and an incidence of 0.7 per 1000 patient-months of treatment. An additional 5 cases of moderate-to-severe ocular irAEs were reported through the national registry. From these 8 patients, 5 presented with intraocular inflammation, 2 with ocular surface disease, and 1 with orbital myopathy. Five patients (62.5%) experienced additional extraophthalmologic irAEs. Ocular irAEs led to permanent discontinuation of anti-PD-(L)1 in 4 patients. Treatment by local and/or systemic corticosteroids allowed resolution or control of the ocular symptoms in 7 of 8 patients. CONCLUSION: Although uncommon, anti-PD-(L)1-associated ocular complications may be sight-threatening and lead to discontinuation of anti-PD-(L)1 treatments. Patients complaining of eye problems while receiving ICI treatment should immediately be seen by an ophthalmologist.

IMPORTANCE: Although immune checkpoint inhibitors (ICIs), such as anti-PD-1 (programmed cell death 1) or anti-PD-L1 (programmed cell death 1 ligand 1), have proved effective in treating many cancers, patients receiving ICIs may experience immune-related adverse events (irAEs). Little evidence exists on the safety of resuming these treatments after an irAE. OBJECTIVE: To investigate the safety of a rechallenge with anti-PD-1 or anti-PD-L1 immunotherapies after an irAE. DESIGN, SETTING, AND PARTICIPANTS: This cohort study of the safety of an ICI rechallenge involved consecutive adult patients (n = 93) who were referred to the ImmunoTOX assessment board at the Gustave Roussy cancer center in Villejuif, France, between August 1, 2015, and December 31, 2017. Data were analyzed from May 28 to November 25, 2018. MAIN OUTCOMES AND MEASURES: Incidence of a second irAE in patients who had a readministration of an anti-PD-1 or anti-PD-L1 inhibitor after an initial grade 2 or higher irAE. Characteristics of the patients and the irAEs were reviewed, and the primary end point was the rate of occurrence of second irAEs. RESULTS: A total of 93 patients were included, among whom 48 (52%) were female, and the median (range) age was 62.5 (33-85) years. The main cancer types or tumor sites were melanoma (31 [33%]), lung (15 [16%]), colorectal (8 [9%]), and lymphoma (8 [9%]). For the initial irAE, 43 grade 2 events (46%), 36 grade 3 events (39%), and 14 grade 4 events (15%) were found, presenting primarily as hepatitis (17 [18%]), skin toxic effect (14 [15%]), pneumonitis (13 [14%]), colitis (11 [12%]), or arthralgia (7 [7.5%]). Forty patients (43%) were rechallenged with the same anti-PD-1 or anti-PD-L1 agent. The rechallenged and non-rechallenged groups did not differ in terms of median (range) age (61 [34-84] years vs 63 [33-85] years; P = .37), time to initial irAE (5 [1-40] treatment cycles vs 3 [1-22] treatment cycles; P = .32), irAE severity (grade 2: 18 [47.5%] vs 27 [51%]; grades 3-4: 22 [52.5%] vs 26 [49%]; P = .70), or steroid use (17 [42.5%] vs 32 [60%]; P = .09). With a median follow-up period of 14 months, the same irAE or a different irAE occurred in 22 patients (55%). Shorter time to the initial irAE was linked to the occurrence of a second irAE (9 vs 15 weeks; P = .04). The second irAEs were not found to be more severe than the first. CONCLUSIONS AND RELEVANCE: The risk-reward ratio for an anti-PD-1 or anti-PD-L1 rechallenge appears to be acceptable, although these patients require close monitoring; further investigation into rechallenge conditions through a prospective clinical trial is needed.
RESUMO
BACKGROUND: Anti-programmed cell death 1 (PD-1) and anti-programmed cell death ligand 1 (PD-L1) antibodies are novel immunotherapies for cancer that can induce immune-related adverse events (irAEs). These adverse events can involve all organs, including the haemopoietic system. Thus far, haematological irAEs (haem-irAEs) have not been extensively characterised. This study aims to provide a comprehensive report of the haem-irAEs induced by anti-PD-1 or anti-PD-L1. METHODS: In this descriptive observational study, we included consecutive patients aged at least 18 years with grade 2 or worse haem-irAEs induced by anti-PD-1 or anti-PD-L1 immunotherapy registered in three French pharmacovigilance databases: the Registre des Effets Indésirables Sévères des Anticorps Monoclonaux Immunomodulateurs en Cancérologie (REISAMIC; a prospective registry of patients treated with anti-PD-1 or anti-PD-L1 at a single centre), the ImmunoTOX committee of Gustave Roussy (a national referral database of suspected irAEs in patients treated with immunotherapy), and the registry of the Centre de Référence des Cytopénies Auto-Immunes de l'Adulte (CeReCAI; a national database of autoimmune cytopenias). Cases were reviewed by a central committee; adverse events had to be classed as certainly or probably related to anti-PD-1 or anti-PD-L1 therapy, and their severity was assessed according to the Common Terminology Criteria for Adverse Events (version 4.03). The primary endpoint was clinical description of haem-irAEs, as reported in all databases, and their frequency, as reported in the prospective REISAMIC registry. FINDINGS: We screened 948 patients registered in the three databases from June 27, 2014, to June 29, 2018 (745 from REISAMIC, 190 from the ImmunoTOX committee, and 13 from CeReCAI). 35 patients (21 men and 14 women) with haem-irAEs related to anti-PD-1 or anti-PD-L1 were included in the study. Of 745 patients in the REISAMIC registry treated with anti-PD-1 or anti-PD-L1, four had haem-irAEs, giving a frequency of 0·5%. Median age in the 35 patients was 65 years (IQR 51-75), and the most common tumour types were melanoma (15 [43%] patients), non-small-cell lung cancer (12 [34%] patients), and lymphoma (four [11%] patients). 20 (57%) patients received nivolumab, 14 (40%) received pembrolizumab, and one (3%) received atezolizumab. Among the 35 patients, neutropenia, autoimmune haemolytic anaemia, and immune thrombocytopenia were the most common types of haem-irAE (each in nine patients [26%]), followed by pancytopenia or aplastic anaemia (five patients [14%]), bicytopenia (one patients with thrombocytopenia plus anaemia and one patient with neutropenia plus anaemia [6%]), and pure red cell aplasia (one patient [3%]). The maximum grade of severity was grade 2 in three (9%) patients, grade 3 in five (14%) patients, and grade 4 in 25 (71%) patients; two (6%) patients died from febrile neutropenia during haem-irAE related to anti-PD-1. Haem-irAEs resolved in 21 (60%) of the 35 patients. INTERPRETATION: Haem-irAEs induced by PD-1 or PD-L1 inhibitors are rare but potentially life-threatening events. The most common clinical presentations are neutropenia, autoimmune haemolytic anaemia, immune thrombocytopenia, and aplastic anaemia. Investigations into earlier detection and better management are warranted. FUNDING: Gustave Roussy and Gustave Roussy Immunotherapy Program.

BACKGROUND: Paraneoplastic syndromes (PNS) are autoimmune disorders specifically associated with cancer. There are few data on anti-PD-1 or anti-PD-L1 immunotherapy in patients with a PNS. Our objective was to describe the outcome for patients with a pre-existing or newly diagnosed PNS following the initiation of anti-PD-1 or anti-PD-L1 immunotherapy. METHODS: We included all adult patients (aged ≥18) treated with anti-PD-1 or anti-PD-L1 immunotherapy for a solid tumor, diagnosed with a PNS, and registered in French pharmacovigilance databases. Patients were allocated to cohorts 1 and 2 if the PNS had been diagnosed before vs. after the initiation of immunotherapy, respectively. FINDINGS: Of the 1304 adult patients screened between June 27th, 2014, and January 2nd, 2019, 32 (2.45%) had a PNS and were allocated to either cohort 1 (n = 16) or cohort 2 (n = 16). The median (range) age was 64 (45-88). The tumor types were non-small-cell lung cancer (n = 15, 47%), melanoma (n = 6, 19%), renal carcinoma (n = 3, 9%), and other malignancies (n = 8, 25%). Eleven (34%) patients presented with a neurologic PNS, nine (28%) had a rheumatologic PNS, eight (25%) had a connective tissue PNS, and four (13%) had other types of PNS. The highest severity grade for the PNS was 1-2 in 10 patients (31%) and ≥ 3 in 22 patients (69%). Four patients (13%) died as a result of the progression of a neurologic PNS (encephalitis in three cases, and Lambert-Eaton syndrome in one case). Following the initiation of immunotherapy, the PNS symptoms worsened in eight (50%) of the 16 patients in cohort 1. INTERPRETATION: Our results show that PNSs tend to be worsened or revealed by anti-PD-1 or anti-PD-L1 immunotherapy. Cases of paraneoplastic encephalitis are of notable concern, in view of their severity. When initiating immunotherapy, physicians should carefully monitor patients with a pre-existing PNS.
