We included a total of 473 tenders for ETN purchase in dedicated biologic drug reimbursement programs, covering both pre-filled syringes and automatic injectors. This study covers the timeframe from November 2017 to December 2023, throughout which we evaluated a unique setting of ETN market re-monopolization from the perspective of payer, hospital and patient benefits resulting from changing cost calculations.</p><p><strong>Results: </strong>Between 2017 and 2022, Erelzi was recorded as having the largest total tender volume (59%), with a mean price [per ETN daily defined dose (DDD)] of €7.28, followed by Enbrel (31%, €8.34) and Benepali (10%, €9.45), respectively. Over the last 6 months of waning market competition, the mean price for winning bids was estimated at €5.69. After market re-monopolization by an ETN biosimilar, the mean price of winning bids increased to €8.09, and continued to increase (€9.71) in the last 6 months of available follow-up. In contrast to the competitive era, no significant relationship between tender volume and winning price was recorded after re-monopolization. In the most recent tenders, mean ETN prices increased up to €15.82, nearly tripling the lowest prices of the competitive market period. In the early re-monopolization market, mean annual treatment cost per patient is estimated at over €3800, which exceeds therapy costs in the prior competitive market years, and is expected to increase to over €6200 based on the most recent tenders. On a healthcare system level, this corresponds to over €3.42 million excess costs due to market monopoly. Higher ETN prices resulted in downstream failure of regulatory incentives to promote affordable biologics. Due to higher pricing, hospitals lost over an estimated €2.52 million, with possible risk of treatment restrictions. For the same reason, the public payer achieved comparable savings, allowing for partial coverage of higher reimbursement expenses.</p><p><strong>Conclusions: </strong>This nation-level scenario of market re-monopolization by a biosimilar drug confirms net loss and excess costs for the healthcare payer, as can be expected from economic theory.

The US Food and Drug Administration has approved ASOs for several diseases. ASOs utilize three principal modes of action (MOA). The first MOA is initiated by base-pairing between the ASO and its target mRNA, followed by RNase H-dependent mRNA degradation. The second MOA is triggered by ASOs that occlude splice acceptor sites in pre-mRNAs leading to skipping of a mutation-bearing exon. The third MOA involves ASOs that sterically hinder mRNA function, often inhibiting translation. ASOs contain a variety of modifications to the sugar-phosphate backbone and bases that stabilize the ASO or render them resistant to RNase activity. RNase H-dependent ASOs include inotersen and eplontersen (for hereditary transthyretin amyloidosis), fomiversen (for opportunistic cytomegalovirus infection), mipomersen (for familial hypercholesterolemia), and tofersen [for amyotrophic lateral sclerosis (ALS)]. Splice modulating ASOs include nursinersen (for spinal muscular atrophy) and eteplirsen, golodirsen, viltolarsen, and casimersen (all for the treatment of Duchenne muscular dystrophy). In addition, a designer ASO, milasen, was used to treat a single individual afflicted with Batten disease.

Reporting odds ratios (ROR) with 95% confidence intervals (CIs) were used as the measure of disproportionality for suspected adverse drug reactions (ADRs) associated with the study drugs compared with either all other suspected drugs (Reference Group 1, RG1) or inhaled corticosteroids plus long-acting β-agonists (ICSs/LABAs) (Reference Group 2, RG2) or with oral corticosteroids (OCSs) (Reference Group 3, RG3).</p><p><strong>Results: </strong>Overall, 31,724,381 ICSRs were identified in VigiBase and 167,282 (0.5%) were related to study drugs; the remaining reports were considered as RG1. Stratifying all biologic-related ICSRs by therapeutic indication, around 29.4% (n = 48,440) concerned asthma use; omalizumab was mainly indicated as the suspected drug (n = 20,501), followed by dupilumab, mepolizumab, benralizumab and reslizumab. Most asthma ICSRs concerned adults (57%) and women (64.1%). Asthma biologics showed a higher frequency of serious suspected ADR reporting than RG1 (41.3% vs 32.3%). The most reported suspected ADRs included asthma, dyspnea, product use issue, drug ineffective, cough, headache, fatigue and wheezing. Asthma biologics were disproportionally associated with several unknown or less documented adverse events, such as malignancies, pulmonary embolism and deep vein thrombosis with omalizumab; alopecia and lichen planus with dupilumab; alopecia and herpes infections with mepolizumab; alopecia, herpes zoster and eosinophilic granulomatosis with polyangiitis related to benralizumab; and alopecia with reslizumab.</p><p><strong>Conclusions: </strong>The most frequently reported suspected ADRs of asthma biologics in VigiBase confirmed the presence of well-known adverse effects such as general disorders, injection-site re","PeriodicalId":9022,"journal":{"name":"BioDrugs","volume":" ","pages":"425-448"},"PeriodicalIF":6.8,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11055782/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140136449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
