For decades, public health communication has centered on broad wellness principles and general disease prevention, often emphasizing lifestyle factors and routine screening. This legacy framework has served to educate populations about common health risks, from cardiovascular disease to infectious threats, without delving into the specific occupational or environmental exposures that can drive rare conditions. As the understanding of disease etiology has matured, however, the need to bridge from these general health contexts to more targeted risk factors has become apparent. In the domain of mass production and industrial settings, workers may encounter a range of chemical and biological agents not typically addressed in general health guidance. One such agent is Avelumab, a therapeutic monoclonal antibody used in oncology, which can inadvertently become an occupational exposure concern during its manufacture, handling, or administration. While the general public may associate health information with diet and exercise, those in production environments face distinct hazards that require specialized awareness. This transition from broad health literacy to occupational risk recognition is essential for identifying potential exposure pathways and their downstream implications, including the rare but serious development of Merkel cell carcinoma. The shift in focus from general wellness to workplace-specific exposures marks a critical evolution in how health information is tailored to protect vulnerable populations.
Avelumab (Bavencio) is a fully human IgG1 monoclonal antibody directed against programmed cell death ligand 1 (PD-L1) and functions as an immune checkpoint inhibitor (https://pubmed.ncbi.nlm.nih.gov/29799096/). It was approved in the USA, the EU, and Japan for the treatment of metastatic Merkel cell carcinoma (MCC), a rare and aggressive neuroendocrine cutaneous malignancy with poor prognosis (https://pubmed.ncbi.nlm.nih.gov/33439294/). Approval was based on the two-part, single-arm, phase II trial JAVELIN Merkel 200, in which confirmed objective responses were observed in approximately one-third of patients with chemotherapy-refractory metastatic MCC (https://pubmed.ncbi.nlm.nih.gov/29799096/). Avelumab is the first therapeutic agent specifically approved for this indication and is approved for use independent of line of treatment (https://pubmed.ncbi.nlm.nih.gov/29799096/). Merkel cell carcinoma is a very rare but highly aggressive cutaneous neuroendocrine carcinoma associated with chronic exposure to ultraviolet light and the Merkel cell polyoma virus (https://pubmed.ncbi.nlm.nih.gov/35877101/). Approximately 80% of cases are caused by the human Merkel cell polyomavirus, while the remaining 20% are induced by UV light leading to mutations (https://pubmed.ncbi.nlm.nih.gov/34445385/). The incidence rate of MCC is increasing, and the disease is associated with high rates of recurrence and mortality (https://pubmed.ncbi.nlm.nih.gov/35877101/). Immune checkpoint inhibitors (ICIs) offer durable responses and significant clinical benefit, with avelumab (anti-PD-L1) and pembrolizumab (anti-PD-1) currently approved by the U.S. Food and Drug Administration for the treatment of advanced MCC (https://pubmed.ncbi.nlm.nih.gov/35877101/).
Despite advances in systemic therapy, approximately 50% of patients with advanced MCC treated with ICI progress on therapy (https://pubmed.ncbi.nlm.nih.gov/35877101/). Furthermore, 50% of patients do not respond or develop ICI-induced, immune-related adverse events (irAEs) due to diverse mechanisms, such as down-regulation of MHC complexes or the induction of anti-inflammatory cytokines (https://pubmed.ncbi.nlm.nih.gov/34445385/). For patients who are refractory to avelumab, efficient and safe treatment options are lacking (https://pubmed.ncbi.nlm.nih.gov/33439294/). In a multicenter study of the prospective skin cancer registry ADOREG, ipilimumab plus nivolumab was evaluated in avelumab-refractory MCC (https://pubmed.ncbi.nlm.nih.gov/36450381/). A retrospective study of ipilimumab plus nivolumab in anti-PD-L1/PD-1 refractory MCC also reported outcomes (https://pubmed.ncbi.nlm.nih.gov/35877101/). In one report, three out of five patients treated at three different academic sites in Germany responded to combined ipilimumab/nivolumab according to RECIST 1.1 (https://pubmed.ncbi.nlm.nih.gov/33439294/). Immune checkpoint inhibition has significantly improved treatment outcomes in metastatic disease, with response rates to PD-1/PD-L1 inhibition of up to 62% (https://pubmed.ncbi.nlm.nih.gov/36450381/).
From a risk perspective, settlement-related considerations for affected patients hinge on several factors. First, the adequacy of warnings regarding avelumab and MCC must be assessed. Avelumab is approved specifically for MCC, and its pharmacology as a PD-L1 inhibitor is well-documented (https://pubmed.ncbi.nlm.nih.gov/29799096/). However, the risk of progression or lack of response in approximately 50% of patients (https://pubmed.ncbi.nlm.nih.gov/35877101/) and the potential for immune-related adverse events (https://pubmed.ncbi.nlm.nih.gov/34445385/) are critical elements. The timeline between exposure to avelumab and documented harm is relevant: patients may experience progression during treatment or develop irAEs, which can occur at any point during therapy. For those who are refractory, the lack of approved subsequent therapies (https://pubmed.ncbi.nlm.nih.gov/33439294/) may compound harm. Settlement criteria would likely consider whether patients were adequately informed of the possibility of non-response or adverse events, and whether alternative treatments were available. The mechanistic pathways linking avelumab to MCC are not causal in the sense of triggering the disease; rather, avelumab is used to treat MCC. However, the drug's mechanism—blocking PD-L1 to enhance T-cell responses—can lead to irAEs (https://pubmed.ncbi.nlm.nih.gov/34445385/). In the context of litigation, the central question is whether the benefits of avelumab were outweighed by risks that were not properly communicated, particularly given that approximately half of patients may not benefit and may experience harm. In summary, avelumab is a key therapy for metastatic MCC, but its efficacy is limited to a subset of patients, and adverse events are common. Settlement considerations should focus on the adequacy of risk communication, the timeline of harm relative to treatment initiation, and the availability of alternative therapies for refractory disease.
