Clinical Research of Pomalidomide Maintenance Therapy for Primary Multiple Myeloma
The trial is a single-center, single-arm, prospective clinical study with a planned enrollment of 15 patients with primary Multiple myeloma(MM), aiming to investigate the efficacy and safety of maintenance therapy with Pomalidomide in patients with primary MM. Patients enrolled were divided into two categories: 1) patients suitable for Autologous Hematopoietic Stem Cell Transplantation(ASCT) started pomalidomide maintenance therapy 3 months after ASCT; 2) patients not suitable for ASCT started pomalidomide maintenance therapy after induction and consolidation therapy to achieve maximum efficacy. Dosing on days 1-21, 2 mg daily for 28 days as a cycle, for a total duration of 36 months or the onset of disease progression, intolerable adverse events. 2-year progression-free survival (2y-PFS) was used as the primary study endpoint, 2-year overall survival (2y-OS), complete remission rate (CR), very good partial remission rate (VGPR), and negative rate of minimal residual disease(MRD) were secondary study endpoints, and the incidence of adverse events (AEs) was assessed.
• Subject diagnosed as initially diagnosed with symptomatic MM by the diagnostic criteria of International Myeloma Working Group(IMWG), aged ≥ 18 years.
• Subject undergoing ASCT who have had prior induction therapy for no more than 12 months and whose disease has not progressed within 3 months of ASCT.
• Subject who are not candidates for ASCT have reached maximum efficacy after induction and consolidation therapy.
• Eastern Cooperative Oncology Group (ECOG) physical status score of 0-3.
• Serum transaminase levels less than three times the upper limit of normal, serum total bilirubin levels not exceeding 35 umol/L, serum creatinine levels less than 177 umol/L, absolute neutrophil values greater than 1.0 x 10\^9/L, and platelet counts greater than 75 x 10\^9/L.
• Subject of childbearing potential must use two reliable methods of contraception simultaneously or have absolutely no sexual relations with the opposite sex for 4 weeks prior to initiation of treatment, during treatment, during suspension of dosing and for 4 weeks after termination of treatment, and women of childbearing potential agree to perform monthly pregnancy tests until 4 weeks after discontinuation of study drug.
• Subject voluntarily enrolled in this study and signed an informed consent form.
