RESUMO
BACKGROUND: In the phase 2 EMPOWER-CSCC-1 study (NCT02760498), cemiplimab demonstrated antitumor activity against metastatic (mCSCC) and locally advanced cutaneous squamous cell carcinoma (laCSCC). OBJECTIVES: To report final analysis of weight-based cemiplimab in mCSCC and laCSCC (Groups 1 and 2), fixed-dose cemiplimab in mCSCC (Group 3), and primary analysis of fixed-dose cemiplimab in mCSCC/laCSCC (Group 6). METHODS: Patients received cemiplimab (3 mg/kg intravenously [IV] every 2 weeks [Groups 1 and 2]) or cemiplimab (350 mg IV [Groups 3 and 6]) every 3 weeks. The primary endpoint was objective response rate (ORR). Duration of response (DOR) and progression-free survival (PFS) are presented per protocol, according to post-hoc sensitivity analyses that only include the period of protocol-mandated imaging assessments. RESULTS: At 42.5 months, ORR for Groups 1-3 (n=193) was 47.2%, estimated 12-month DOR was 88.3%, and median PFS was 26.0 months. At 8.7 months, ORR for Group 6 (n=165 patients) was 44.8%; median DOR and median PFS were not reached. Serious treatment-emergent adverse event rates (grade ≥3) were Groups 1-3: 31.1% and Group 6: 34.5%. LIMITATIONS: Non-randomized study, non-survival primary endpoint. CONCLUSION: EMPOWER-CSCC-1 provides the largest prospective data on long-term efficacy and safety for anti-programmed cell death-1 therapy in advanced CSCC.
RESUMO
A 62-year-old man presented with a slowly growing, painless lesion on his face. This eventually led to a progressive left-eye vision lesion, and the patient was subsequently diagnosed with advanced basal cell carcinoma (BCC). Of note, BCC involving cranial nerves is extremely rare, making this case unique and important to highlight. Standard treatment options for BCC involve surgery, radiation, or platinum-based chemotherapy. However, targeted therapies such as sonidegib and vismodegib - sonic hedgehog pathway inhibitors - have emerged that have been approved for treating BCC, as have anti-PD1 immunotherapies, such as cemiplimab, with their success likely based on the high tumor mutational burden seen in some of these tumors. Epidermal growth factor receptor (EGFR) inhibitors also serve a role in treating this condition as well. Molecular studies on metastatic/advanced BCC and other rare malignancies may inform treatment therapeutic decisions.
RESUMO
Cemiplimab has demonstrated relevant clinical activity in cutaneous squamous cell carcinoma (cSCC) but mechanisms of primary and acquired resistance to immunotherapy are still unknown. We collected clinical data from locally advanced and/or metastatic cSSC patients treated with cemiplimab in two Italian University centers. In addition, gene expression analysis by using Nanostring Technologies platform to evaluate 770 cancer- and immune-related genes on 20 tumor tissue samples (9 responders and 11 non-responders to cemiplimab) was performed. We enrolled 81 patients with a median age of 82 years. After 16.4 months of median follow-up, 12- and 24-months PFS were 53% and 42%, respectively; while 12- and 24-months OS were 71% and 61%, respectively. Treatment was well tolerated. Overall response rate (ORR) was 58%, with a disease control rate (DCR) of 77.8%. The difference between genes expressed in responder versus non-responder patient samples was substantial, particularly for genes involved in immune system regulation. Cemiplimab-resistant tumors were associated with over-expression of CCL-20 and CXCL-8. Cemiplimab confirmed efficacy and safety data in real-life cSCC patients. Overexpression of CCL-20 and CXCL-8 could represent biomarkers of lack of response to immunotherapy.

In December 2020, a major vaccination program against COVID-19 commenced in Europe with vaccines such as Pfizer's mRNABNT162b2 (Comirnaty®). Subsequent reports of immediate and delayed skin reactions emerged. This study presents a case of a 64-year-old male who developed multiple keratoacanthomas approximately two weeks after receiving a second booster dose of the Pfizer vaccine. The patient, who had significant medical history of hypertension and diabetes, presented with erythematous, crateriform lesions on his limbs. A physical examination and histopathological analysis confirmed the diagnosis of Generalized Eruptive Keratoacanthoma (GEKA). Treatment involved cemiplimab I.v. 350 mg administered every three weeks. Within two months, the patient showed significant improvement, with the disappearance of all lesions. Dermoscopy and histopathological exams supported the GEKA diagnosis, which is a rare variant of multiple keratoacanthomas. This case suggests a potential immune-mediated mechanism triggered by the COVID-19 vaccine, leading to the rapid development of keratoacanthomas. Treatment with cemiplimab showed promise, highlighting the potential of immune checkpoint inhibitors in managing multiple keratoacanthomas. Further research is needed to explore the efficacy and safety of such treatments.

BACKGROUND: A phase 2 cemiplimab study (NCT03132636) demonstrated a 24.1% objective response rate in patients diagnosed with metastatic basal cell carcinoma (mBCC) who were not candidates for continued hedgehog inhibitor (HHI) therapy due to intolerance to previous HHI therapy, disease progression while receiving HHI therapy, or having not better than stable disease on HHI therapy after 9 months. Here, health-related quality of life (QoL) for this patient population is reported. METHODS: Adult patients with mBCC were treated with intravenous cemiplimab at a dose of 350 mg every 3 weeks for 5 treatment cycles of 9 weeks/cycle then 4 treatment cycles of 12 weeks/cycle. Patients completed the European Organisation for Research and Treatment of Cancer Quality of Life-Core 30 (QLQ-C30) and Skindex-16 questionnaires at baseline and Day 1 of each cycle. Across Cycles 2 to 9, the overall change from baseline was analyzed using a mixed model with repeated measures. Responder analyses determined clinically meaningful improvement or deterioration (changes ≥10 points) or maintenance across all scales. RESULTS: Patients reported low symptom burden and moderate-to-high functioning at baseline. Maintenance for QLQ-C30 global health status (GHS)/QoL and across all functioning and symptom scales was indicated by overall mean changes from baseline. Clinically meaningful improvement or maintenance was reported at Cycle 2 for GHS/QoL (77%), functioning scales (77% to 86%), and symptom scales (70% to 93%), with similar proportions of improvement or maintenance at Cycles 6 and 9, excluding fatigue. On the Skindex-16, clinically meaningful improvement or maintenance was reported across the emotional, symptom, and functional subscales, in 76%-88% of patients at Cycle 2, which were generally maintained at Cycles 6 and 9. Overall mean changes from baseline showed maintenance across these subscales. CONCLUSIONS: The majority of patients treated with cemiplimab reported improvement or maintenance in GHS/QoL and functioning while maintaining a low symptom burden.

Aim: To evaluate health-related quality of life (HRQoL) in cemiplimab-treated patients with locally advanced basal cell carcinoma (laBCC).Materials & methods: Eighty-four patients with laBCC received cemiplimab 350 mg every 3 weeks (up to 9 cycles). HRQoL was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Core 30 (QLQ-C30) and Skindex-16 questionnaires at baseline and each cycle. Mixed-effects repeated-measures models evaluated change from baseline across cycles.Results: Clinically meaningful improvement or maintenance was reported by 62-90% of patients on QLQ-C30 scales and by approximately 80% on Skindex-16 scales at Cycle 2, with consistent results at Cycle 9 except fatigue.Conclusion: Most cemiplimab-treated patients with laBCC reported improvement or maintenance of HRQoL with low symptom burden except fatigue.Clinical Trial Registration: ClinicalTrials.gov identifier NCT03132636, registered 28 April 2017.
Locally advanced basal cell carcinoma (laBCC) is a type of skin cancer that has the potential to invade surrounding tissues including bone, cartilage, nerve and muscle. Cemiplimab-rwlc is approved in the US for patients with laBCC following a therapy called hedgehog inhibitor (HHI) treatment or for whom HHIs are not appropriate. In a Phase II clinical trial, intravenous (in the vein) cemiplimab 350 mg every 3 weeks for up to nine treatment cycles resulted in clinically meaningful antitumor activity in patients with laBCC who progressed on or were intolerant to HHIs.This analysis evaluated health-related quality of life, symptom burden, emotions and functional status in these patients using the European Organization for Research and Treatment of Cancer Quality of Life Core 30 (QLQ-C30) and Skindex-16 questionnaires. Baseline scores (scores at the start of the clinical trial) showed moderate to high levels of functioning and low symptom burden that, except for fatigue, were maintained or improved over the course of cemiplimab treatment. These results show that despite the presence of fatigue, health-related quality of life and functional status were maintained with cemiplimab across the study duration.
RESUMO
Non-melanoma skin cancers (NMSC) form the majority of skin cancers, with basal cell carcinoma (BCC) being the most common and cutaneous squamous cell carcinoma (cSCC) being second. Prolonged ultraviolet (UV) exposure, aging, male gender, and immunosuppression represent most of the causes of this category of diseases. BCCs and cSCCs both include different types of skin cancers, such as nodular or morpheaform BCC or flat cSCC. Locally advanced and metastatic NMSCs cannot be treated surgically; thus, systemic therapy (TKI and Immunotherapy) is needed. Interestingly, NMSCs are frequently linked to abnormal Hedgehog (HH) signaling which most systemic immunotherapies for these cancers are based upon. Of note, the first line therapies of BCC, sonidegib and vismodegib, are HH inhibitors. Programmed death receptor 1 antibody (PD-1) inhibitors such as cemiplimab, pembrolizumab, and nivolumab have been approved for the treatment of cSCC. Thus, this paper reviews the epidemiology, risk factors, clinical features, and treatment options for both BCC and cSCC.
RESUMO
Background: Cemiplimab was licensed in the United Kingdom (UK) in 2019 for the treatment of patients with locally advanced and metastatic CSCC not suitable for curative surgery or radiotherapy (advanced CSCC [aCSCC]). No UK multi-center studies have investigated the real-world experience of cemiplimab post marketing authorization in aCSCC. Methods: This non-interventional retrospective study (10 UK centers) involved data collection from medical records of patients with aCSCC who initiated cemiplimab treatment between 2 July 2019 and 30 November 2020. The study period was a minimum of 12 and a maximum of 36 months post cemiplimab initiation. The primary objective was to describe the real-world clinical effectiveness of cemiplimab (primary outcome: overall response rate [ORR]). Results: Of 105 patients, 70% (n=73/105) were male (median [range] age at index of 78.5 [55.4-93.2] years); most patients (63% [n=50/80]) had an Eastern Cooperative Oncology Group (ECOG) score of 1 and 62% (n=63/102) had metastatic disease. The ORR within 12 months was 42% (95% confidence interval [CI] 32%-51%) and the disease control rate was 62% (n=65/105). The median (95% CI) real-world progression-free survival and overall survival from index was 8.6 (6.0-18.7) and 21.0 (14.7-25.2) months, respectively. The median (range) number of cemiplimab infusions was 11.0 (1.0-44.0). Eighty-seven percent experienced no cemiplimab treatment interruptions; 13% (n=14/105) interrupted treatment due to immune-related adverse reactions (irARs) (47% [n=9/19] of treatment interruption events). Eighty-five percent (n=89/105) of patients had discontinued cemiplimab treatment by the end of the study; where reasons for discontinuation were recorded, 20% (n=17/87) discontinued due to the completion of their 2-year treatment course. Nineteen percent (n=20/105) of patients experienced irARs. Conclusion: Effectiveness and safety data in this study are broadly similar to previous real-world studies of cemiplimab and the EMPOWER-CSCC1 clinical trial; with our cohort representing a broader population (included immunocompromised and transplant patients). Results support the use of cemiplimab for the treatment of aCSCC in a real-world setting.

Background: Prior to the Food and Drug Administration approval of cemiplimab in 2018, the median overall survival (OS) for adult patients with advanced CSCC receiving systemic therapy was approximately 8 to 15 months. Limited real-world data are available on cemiplimab for this indication in the US. Patients and Methods: This retrospective cohort study included US patients with advanced CSCC initiating cemiplimab monotherapy in a real-world database (2018-2021). A clinical trial-like sub-cohort was identified using select criteria. Time to treatment discontinuation (TTD), time to next treatment (TTNT), and OS were estimated using Kaplan-Meier methods. Cox proportional hazard models were used to examine prognostic factors associated with OS in the main cohort. Results: The main cohort included 622 patients (n = 240 in the trial-like cohort). In the main cohort, the median age was 78 years, 77.8% were male, 21.4% were immunocompromised/immunosuppressed, and 63.8% had metastatic CSCC. Median (95% CI) TTD and TTNT were 8.0 (6.6-9.0) months and 16.4 (13.3-21.0) months, respectively, in the main cohort. Median (95% CI) OS was 24.8 (21.8-29.1) months in the main cohort (not reached in the trial-like cohort). In multivariable analyses, age <60 years (hazard ratio [HR], 0.37), Eastern Cooperative Oncology Group performance status <3-4 (HR range, 0.13-0.57), and primary CSCC location in the head and neck only versus extremities only (HR, 0.59) were associated with better OS. Similar OS was observed between patients who had immunosuppressing/immunocompromising conditions and those without. Conclusion: These findings confirm the effectiveness of cemiplimab among a heterogenous, real-world advanced CSCC patient population and substantiate the efficacy of cemiplimab observed in clinical trials.
RESUMO
In this retrospective case series, we investigate the synergistic effect and the immunomodulatory potential of combination radiotherapy and immunotherapy on 11 patients affected by locally advanced or metastatic cutaneous squamous cell carcinoma (CSCC), treated at our institution between 2020 and 2023. The primary endpoints of this study are objective tumor response, assessed by Immunotherapy Response Evaluation Criteria in Solid Tumors (iRECIST), and time to treatment failure (disease progression). In all patients, surgery was deemed not amenable, due to its potential functional and aesthetic impact. Therefore, upon multidisciplinary agreement, radiotherapy and immunotherapy with cemiplimab were alternatively administered. After 6 months, an early objective tumor response was observed in 9/11 patients, with 17/20 cutaneous lesions (85%) presenting either a complete or partial response. Only 2/11 patients, with a total of 3/20 cutaneous lesions (15%), had stable disease. These benefits persisted at a longer follow-up (21.4 ± 9.7 months), with no patients presenting disease progression. Despite the retrospective nature of this study and small sample size, our experience highlights the ability of concomitant radiotherapy and cemiplimab to promote an early objective response in patients with advanced CSCC. Moreover, in our population, the clinical benefits were also related to a longer progression-free survival, without any safety alert reported.
RESUMO
Treatment duration with checkpoint inhibitors must be optimized to prevent unjustified toxicity, but evidence for the management of cutaneous squamous cell carcinoma is lacking. A retrospective study was performed to evaluate the survival of patients with cutaneous squamous cell carcinoma (CSCC) who discontinued cemiplimab due to different causes and without progression. Among 95 patients with CSCC who received cemiplimab, 22 (23%) patients discontinued immunotherapy due to causes other than progression, such as comorbidities, toxicity, complete response or lack of compliance (group that discontinued before censoring [DBC]), then 73 patients had standard treatment scheduled (STS). The overall survival was 25.2 months (95% CI: 8.9-29.4) in STS group and 28.3 months (95% CI: 12.7-28.3) in the DBC group; deaths for all causes were 11/22 (50%) in the DBC group and 34/73 (46.6%) in the STS group (p = 0.32). 10/22 (45.4%) subjects died due to CSCC in the DBC after discontinuation and 34/73 (46.6%) in the STS group, and the difference between groups was not significant (p = 0.230). Duration of treatment was significantly lower in subjects with stable disease versus those with complete or partial response (16.9, 30.6 and 34.9 months, respectively; p = 0.004). Among the 22 STS patients, 12 received cemiplimab for less than 12 months (10 [83%] died) and 10 for at least 12 months (1 [10%] died). Our observation, finding no outcome difference between DBC and STS groups, suggests that ICI treatment after one year might expose patients to further treatment related events without efficacy advantages.

BACKGROUND: Cemiplimab, a programmed cell death-1 inhibitor approved in 2018 for patients with locally advanced or metastatic cutaneous squamous cell carcinoma (cSCC) who are ineligible for curative therapies, lacks clarity regarding the optimal patient selection despite its known efficacy. OBJECTIVE: This retrospective study aims to assess the real-world treatment patterns and outcomes in patients with cSCC at our institution. METHODS: A retrospective analysis of consecutively treated patients with cemiplimab for cSCC was conducted. Progression-free survival (PFS) and overall survival were evaluated alongside clinical-pathologic characteristics. RESULTS: Forty-five patients were included, of which 73.3% were male with a median age of 77 years. After 18 months of median follow-up median PFS and overall survival were not reached with a mean of 21.3 months ± 2.2 months and 25.3 ± 2.1 months, respectively. Univariate and multivariate analyses revealed significant correlations only between PFS and previous radiotherapy (P values: .043 and .046, respectively). LIMITATIONS: Limitations include its retrospective nature, the low number of patients analyzed, and the potential for inherent biases. CONCLUSIONS: The study reveals a significant association between prior radiotherapy and improved PFS in cemiplimab-treated cSCC, suggesting the potential for combining radiotherapy with cemiplimab. Further exploration of this combined approach is warranted.
RESUMO
BACKGROUND: Immune Checkpoint Inhibitors (ICI) have been widely used in treating different types of cancer. They increase survival in many oncologic patients and enable cancer-specific therapy. Acute Kidney Injury (AKI) is one of the adverse effects associated with using ICI, where knowledge of the prevalence and renal histological findings are still reasons for discussion. OBJECTIVE: Therefore, this meta-analysis evaluates the association between ICI use and AKI. METHODS: The search was performed in PubMed, Lilacs, and Cochrane platforms. Studies published up to December 1, 2022, were included. RESULTS: A total of 16 studies met the established PICOT criteria and were included in this review. Comparing the ICI plus chemotherapy against chemotherapy alone, the relative risk (RR) for AKI's development with ICI use was 2.89 (95%CI 1.37-6.10). In the analyses by class and drug type, programmed cell death 1 monoclonal antibody (anti-PD-1) showed an increased risk of 2.11 (95%CI 1.26-3.52), and pembrolizumab demonstrated a risk of AKI (RR= 2.77, 95%CI 1.46-5.26). Likewise, regarding the severity of AKI, AKI grade 3 or higher was more common in the ICI plus chemotherapy compared to the chemotherapy group: 3.66 (95%CI 1.19-11.30), while the subgroup analyses pooled studies comparing ICI alone versus chemotherapy alone in the control group did not demonstrate an association with AKI. CONCLUSIONS: These findings suggest that ICI use is associated with an increased risk of AKI and that anti-PD-1 use is associated with a higher incidence of renal adverse events than programmed cell death ligand 1 monoclonal antibody (anti-PD-L1). Studies with adequate power and well-defined criteria for acute interstitial nephritis, nowadays taken as a synonym for AKI related to ICI, are necessary.

BACKGROUND: In a princeps study we conducted in patients with advanced cutaneous squamous cell carcinoma treated with concomitant anti-Programmed cell death protein 1 (PD-1) and radiotherapy, we demonstrated a clinico radiological response to cemiplimab that appeared to persist over time, 1 year after treatment discontinuation. METHOD: We conducted a single-center descriptive study at Caen Hospital from September 1, 2021 to September 2023, in 14 patients with advanced carcinoma treated with cemiplimab until September 1, 2021. The aim of this update is to examine clinical and radiological follow-up 2 years after discontinuation of cemiplimab. RESULTS: Of the 12 patients with a partial or complete response, we report 8 (66.7%) persistent responses 2 years after stopping cemiplimab, with only 2 patients progressing to distant disease, one lost to follow-up, and one death a priori unrelated to the disease. CONCLUSION: Our study confirms a long-term and persistent effect despite discontinuation of cemiplimab at least up to 2 years later.

OBJECTIVES: EMPOWER-Lung 3 part 2 (NCT03409614), a double-blind, placebo-controlled phase 3 study, assessed cemiplimab (anti-programmed cell death protein 1) plus chemotherapy versus chemotherapy alone in patients with advanced non-small cell lung cancer (NSCLC) without EGFR, ALK, or ROS1 aberrations, regardless of histology or PD-L1 expression levels. We report results from subgroup analysis of patients with PD-L1 expression ≥ 1 %. MATERIALS AND METHODS: Patients were randomized to receive cemiplimab 350 mg or placebo with chemotherapy every 3 weeks for up to 108 weeks. Overall survival (OS), progression-free survival (PFS), overall response rates (ORRs), patient-reported outcomes (PROs), and safety were assessed. RESULTS: Of the 327 patients with PD-L1 ≥ 1 % (466 in the overall study), 217 received cemiplimab plus chemotherapy and 110 received chemotherapy alone. After median follow-up of 28.0 months, median OS for cemiplimab plus chemotherapy was 23.5 months (95 % confidence interval [CI]: 20.9-27.2) vs. 12.1 months (95 % CI: 10.1-15.7) for chemotherapy alone (hazard ratio [HR] = 0.51, 95 % CI: 0.38-0.69, P < 0.0001); median PFS was 8.3 months (95 % CI: 6.7-10.8) versus 5.5 months (95 % CI: 4.3-6.2; HR = 0.48; 95 % CI: 0.37-0.62, P < 0.0001), and ORR was 47.9 % versus 22.7 %, respectively. PRO results favored cemiplimab plus chemotherapy over chemotherapy alone. Improved efficacy over chemotherapy alone was observed in both squamous and non-squamous histology. Safety was consistent with previous reports. CONCLUSION: In this subgroup analysis from EMPOWER-Lung 3 part 2, cemiplimab plus chemotherapy demonstrated clinical benefit over chemotherapy alone in patients with advanced squamous or non-squamous NSCLC with PD-L1 ≥ 1 %.

Non-melanoma skin cancer includes several types of cutaneous tumors, with basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC) as the commonest. Among the available therapeutic options, surgical excision is the mainstay of treatment for both tumors. However, tumor features and patients' comorbidities may limit the use of these techniques, making the treatment challenging. As regards BCC, even if hedgehog inhibitors revolutionized the therapeutic scenario, there are still patients unresponsive or intolerant to these drugs. In this context, cemiplimab has been approved as second-line treatment. As regards SCC, cemiplimab was the first systemic therapy approved. The objective of this manuscript was to investigate the efficacy and safety of cemiplimab for the management of BCC and cSCC. Cemiplimab has a durable and significant effect for the management of BCC and CSCC, with a favorable safety profile. Different specialists including oncologists, radiologists, dermatologists, and surgeons are required to guarantee an integrated approach, leading to the best management of patients. Moreover, the collaboration among specialists will allow them to best manage the TEAEs, reducing the risk of treatment suspension or discontinuation. Certainly, ongoing studies and more and more emerging real-world evidence, will allow us to better characterize the role of cemiplimab for the management of advanced non-melanoma skin cancer.
RESUMO
Cutaneous squamous cell carcinoma (CSCC) accounts for â¼20%-25% of all skin tumors. Its precise incidence is often challenging to determine due to limited statistics and its incorporation with mucosal forms. While most cases have a favorable prognosis, challenges arise in patients presenting with locally advanced or metastatic forms, mainly appearing in immunocompromised patients, solid organ transplantation recipients, or those facing social difficulties. Traditionally, chemotherapy and targeted therapy were the mainstays for advanced cases, but recent approvals of immunotherapeutic agents like cemiplimab and pembrolizumab have revolutionized treatment options. These guidelines, developed by the Italian Association of Medical Oncologists (AIOM) using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach, aim to guide clinicians in diagnosing, treating, and monitoring patients with CSCC, covering key aspects from primitive tumors to advanced stages, selected by a panel of experts selected by AIOM and other national scientific societies. The incorporation of these guidelines into clinical practice is expected to enhance patient care and address the evolving landscape of CSCC management.
