Adverse Effects and Safety of Etirinotecan Pegol, a Novel Topoisomerase Inhibitor, In Cancer Treatment: A Systematic Review

Background: Due to the increasing prevalence of cancer and the inadequacy of current therapies, the development of novel antitumor pharmaceutics with higher efficacies and lower adverse effects is considered a fundamental tenet of contemporary cancer management. Poly-Ethylene-Glycol (PEG) attachment is a novel pharmaceutical technology to improve the efficacy and safety of chemotherapies. Etirinotecan Pegol (EP), also known as NKTR-102, is the PE-Gylated form of Irinotecan (CPT-11), which causes cancer cell apoptosis by inhibiting the topoisomerase I enzyme. Objective: The present study reviews and evaluates various reports of the EP’s anti-tumor activity in various cancers. Data Source: Studies were identified using the Scopus database, with no exclusions. The search terms included Etirinotecan Pegol and NKTR-102, which yielded 125 articles (66 and 59 articles, respectively). In addition, the clinicaltrials.gov website was used to find ongoing studies, which re-sulted in the addition of two studies. Study Eligibility Criteria: Subsequently, we excluded studies that were published in languages other than English, duplicate articles, and studies with no data. Results: This systematic review clarifies that EP possesses numerous advantages over many other medications, such as safety, efficacy, increased half-life, increased health-related quality of life, increased overall survival, increased progression-free survival, and decreasing the adverse events in the treatment of various cancers. Conclusion: Therefore, Etirinotecan Pegol may represent a major contribution to the treatment of various cancers in the future.
