{"doi":"10.1002/pbc.28244","title":"Higher plasma asparaginase activity after intramuscular than intravenous Erwinia asparaginase","abstract":"Abstract It is unclear if dosing intervals for Erwinase can be extended with intramuscular (i.m.) versus intravenous (i.v.) dosing. Children with acute lymphoblastic leukemia received Erwinase at 30 000‐42 000 IU/m 2 i.v. or i.m. I.m. Erwinase ( n = 22) achieved activity above 0.1 IU/mL for longer than i.v. Erwinase ( n = 33) (3.4 vs 2.9 days, P = 0.0007). With 30 000 IU/m 2 Monday, Wednesday, Friday, more patients achieved adequate concentrations over the weekend with i.m. vs i.v. dosing ( P = 5 × 10 −36 ). A schedule with i.v. doses on Monday and Wednesday and i.m. doses on Friday of 30 000 IU/m 2 maintained activity > 0.1 IU/mL over the weekend in 80% of patients.","journal":"Pediatric Blood & Cancer","year":2020,"id":107966,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":5,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9544,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":517893,"name":"Yiwei Liu","orcid":"0000-0002-7544-5261","position":1,"is_corresponding":false},{"id":451829,"name":"Hope D.
