First, we retrospectively analyzed 278 allo-HCT recipients between 2007 and 2017 (Period 1). We scored risk factors for higher CMV-AUC by odds ratios: malignant lymphoma including adult T cell leukemia/lymphoma (1 point), an unrelated or haploidentical donor (1 point), and recipient/donor CMV serostatus (+/+; 2 points, +/-; 3 points). We have administered LTV to patients with a total score of ≥ 4 points. We then focused on 143 patients who underwent allo-HCT when we applied this strategy (Period 2). Forty patients (28%) in Period 2 received LTV prophylaxis. Two patients (5.4%) exhibited higher CMV-AUC among 37 patients in the higher-risk group (≥ 4 points). However, as many as 33% of the patients with 3 points in Period 2 experienced higher CMV-AUC. Notably, in the lower-risk patients of Period 2, 68% of patients who received systemic steroids for acute graft-versus-host-disease (GVHD) developed higher CMV-AUC. Our risk-adapted LTV prophylaxis strategy effectively prevented higher CMV-AUC in the higher-risk group and reduced the use of LTV.

Through these studies, TIL developers have gained an immunological perspective into the mechanism of action (MoA) and infusion product characteristics that influence clinical response. However, to reach marketing authorization for any of the TIL MPs, it will be beneficial to gain a pharmaceutical (process) development perspective as well, from which control of the TIL MPs manufacturing process can be demonstrated and a suitable control strategy can be developed. To do this, a well-defined TIL MP must be established. Defining and optimizing MPs from a pharmaceutical perspective is done by identifying and improving product characteristics or quality attributes (QAs) thought to impact safety and efficacy. Through awareness of the QAs relevant to TIL MPs and considering them throughout pharmaceutical development, improvements and changes can be validated. This approach to pharmaceutical development is part of the quality-by-design workflow, of which this review tackles the first steps. Here, the QAs are structured within a quality target product profile (QTPP), and the corresponding regulatory expectations are considered, spanning quantity, identity, purity, microbiological assays, and biological activity. Based on the regulatory expectations and available literature, the (critical) QAs and points of consideration are proposed when developing TIL MPs. The active pharmaceutical ingredient of the TIL MP is defined as the CD45+CD3+ cells. By analyzing identity attributes correlated to clinical efficacy, four broadly applicable <em>in vivo</em> functionalities associated with TIL MPs MoA and clinical effectiveness are described: tumor recognition, cytotoxic capacity, tumor homing, and persistence. How these <em>in vivo</em> functionalities are quantified in potency assays and the limitations of their methods/readouts are also discussed. The QTPP is a foundation for developing a robust, substantiated control strategy for regulatory approval and increasing patient access. Harmonizing TIL MP development under a unified QTPP applicable in different settings could also facilitate comparisons and, therefore, the development of safer and more efficacious TIL MP variations.</div></div>","PeriodicalId":23283,"journal":{"name":"Transplantation and Cellular Therapy","volume":"31 3","pages":"Pages S610-S625"},"PeriodicalIF":3.6,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143610676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
