ABSTRACT
INTRODUCTION: In a context of intensive clinical development and innovation in oncology, the French National Cancer Institute has developed a horizon scanning focused on emerging anticancer drugs since 2019. This tool aims to provide further insight to national authorities responsible of the access to medicines and policymakers. METHODS: EMERGINCaRE is based on an annual cycle initiated by the identification of clinical developments of interest from a database, one to three years prior European marketing authorization. Clinical developments are ranked and prioritized using a scoring approach. Scores are based on public information about developments collected by the Institute and on the evaluation carried out by clinicians who were asked to analyse and identify the most impacting drugs. A national steering committee prioritizes several high-score developments each year. RESULTS: Seventy-five developments were analysed during the 2023 cycle. Among these developments, 50 are related to drugs for solid tumors and 25 for hematological malignancies. At the end of this cycle, six developments, including two concerning Advanced Therapy Medicinal Products, were prioritized. Half of these prioritized developments evaluate a drug for a poor prognosis cancer. DISCUSSION: Among the developments evaluated with a high clinical impact score, some drugs were finally approved for the clinical situation concerned. As first public Horizon Scanning in France, the methodology of EMERGINCaRE has been refined and deadlines have been optimized to provide annually the information generated by this system to interested public institutions.
ABSTRACT
BACKGROUND: Safety of rechallenge of immune checkpoint inhibitor (ICI) after grade ≥2 immune-related adverse events (irAEs) leading to ICI discontinuation remains unclear. METHODS: All adverse drug reactions involving at least one ICI reported up to December 31, 2019 were extracted from the French pharmacovigilance database. Patients were included if they experienced at least one grade ≥2 irAE resulting in ICI discontinuation, with subsequent ICI rechallenge. The primary outcome was the recurrence of at least one grade ≥2 irAE in these patients after ICI rechallenge. RESULTS: We included 180 patients: 61.1% were men (median age of 66 years), 43.9% had melanoma and 78.9% were receiving anti-programmed cell death 1. First ICI discontinuation was related to 191 irAEs. After ICI rechallenge, 38.9% of the patients experienced at least one grade ≥2 irAE. Among them, 70.0% experienced the same irAE, 25.7% a distinct irAE, and 4.3% both the same and a distinct irAE. Lower recurrence rates of irAEs were associated with rechallenge with the same ICI treatment (p=0.02) or first endocrine irAEs (p=0.003). Gastrointestinal irAEs were more likely to recur (p=0.007). The median duration from ICI discontinuation to rechallenge and the severity of the initial irAE did not predict recurrent irAEs after ICI rechallenge (p=0.53 and p=0.40, respectively). CONCLUSIONS: In this study, 61.1% of the patients who discontinued ICI treatment for grade ≥2 irAEs experienced no recurrent grade ≥2 irAEs after ICI rechallenge. Although ICI rechallenge appears to be safe under close monitoring, it should always be discussed balancing usefulness of rechallenge, patient comorbidities and risk of recurrence of first irAE(s). Due to inherent bias associated with pharmacovigilance studies, further prospective studies are needed to assess risk factors that may influence patient outcomes after ICI rechallenge.

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.
