ABSTRACT
BACKGROUND: To evaluate the efficacy and safety of pomalidomide in combination treatment of relapsed/refractory multiple myeloma (RRMM). METHODS: Published clinical trials were searched in the Cochrane Library, PubMed, EMBASE to February 2023. The literature was screened and evaluated according to the inclusion criteria, and the data were analyzed by a random effect model. Overall response rate (ORR), overall survival (OS), progression-free survival (PFS) and full grade or ≥ 3 adverse events (AEs) were the outcomes. RESULTS: This study included 31 clinical trials, which included 4776 patients. The pooled ORR of the doublet regimens was 33.3% (95%CI: 27-39%) and the triplet regimens was 66% (95%CI: 58-74%). Among the 25 included studies, the median PFS was 8.29 months (95%CI: 7.27-9.31), and nine studies reported median OS of 19.43 months (95%CI: 14.56-24.30). In terms of safety, the most common hematologic AEs of grade ≥ 3 were neutropenia (41%) and anemia (20%); Non-hematologic AEs were pneumonia (14%) and infection/febrile neutropenia (14%). CONCLUSIONS: Pomalidomide combined treatment regimens have shown good clinical efficacy, especially in pomalidomide + dexamethasone combined with other drugs. In terms of safety, it's important to pay attention to the likelihood of hematological adverse events when used clinically.
ABSTRACT
BACKGROUND: SAR107375E is a direct dual inhibitor of both Factor Xa and Factor IIa and has shown potent anticoagulation activity in vitro and animals. This study evaluated the safety, tolerability, pharmacokinetics, and pharmacodynamics of single ascending intravenous doses of SAR107375E in healthy Chinese adult subjects. METHODS: In this randomized, double-blind, placebo-controlled trial, 60 healthy Chinese adult subjects were administered intravenously single ascending doses (0.5, 1.5, 3.0, 5.0, 7.5, 10.0, 15.0, or 20.0 mg) of SAR107375E (N = 44) or placebo (N = 16). Plasma and urine concentrations of SAR107375E were measured and used to calculate pharmacokinetic parameters. Coagulation functions were measured and compared with baseline values. Treatment-emergent adverse events were recorded to evaluate safety. RESULTS: In plasma, from the 0.5 to 20.0 mg dose group, t1/2 is 1.51-4.00 h, Cmax is 59.05-1360 ug/L, and AUC0-t is 25.01-528.45 h*ug/L. And it shows dose proportionality in the 5.0-20.0 mg range. Activated partial thromboplastin time and Ecarin clotting time correlated linearly with drug plasma concentration. No serious adverse events were reported during the study. CONCLUSION: SAR107375E exhibits good safety and tolerability, predictable pharmacokinetics and pharmacodynamics. CLINICAL TRIAL REGISTRATION: www.chinadrugtrials.org.cn, identifier is CTR20211082.
