For these patients, effective therapeutic options are urgently warranted.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In this retrospective study, we report on the safety and efficacy of the intensive combination regimen of pomalidomide plus cisplatin, doxorubicin, cyclophosphamide, and etoposide (Pom\u2010PACE) in patients with relapsed refractory MM (RRMM) or plasma cell leukemia (PCL). A study population of 20 consecutive patients treated with Pom\u2010PACE at two academic centers was included for analysis. All patients had to have a confirmed relapse according to International Myeloma Working Group criteria and adequate organ function prior to the start of therapy. Data were collected by reviewing medical charts. Exploratory analyses were performed with regard to efficacy and safety.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Patients were heavily pretreated with a median number of four prior therapies (range: 1\u201310). All patients were exposed to immunomodulators, proteasome inhibitors, and alkylating agents, 80% were double\u2010class refractory, 40% were triple\u2010class refractory. Extramedullary MM or PCL were present in 15 patients (75%). Overall response rate (ORR) was 68%, with 31% achieving at least a very good partial response. Responses were achieved rapidly with an ORR of 64% after one cycle. Median progression\u2010free survival was 8.9\u2009months (0.92\u2013not reached [NR]) and median overall survival was 11.8\u2009months (3\u201340.6). Pom\u2010PACE was associated with significant toxicity. All evaluable patients experienced Grade 4 hematological toxicity. However, no treatment related mortality was observed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Pomalidomide\u2010PACE was able to induce rapid responses in heavily pretreated, aggressive RRMM with a manageable toxicity profile and therefore offers an effective salvage regimen and a potential bridging strategy to further treatment options such as chimeric antigen receptor T\u2010cell therapy.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ejh.14254","type":"journal-article","created":{"date-parts":[[2024,6,20]],"date-time":"2024-06-20T04:24:59Z","timestamp":1718857499000},"page":"465-471","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Retrospective
