IL-15 is a cytokine that stimulates the proliferation of NK and T cells. Previous studies have shown that IL-15 is critical to the induction of T-cell large granular lymphocyte (T-LGL) leukemia. A Phase I trial of a humanized antibody (Hu-Mikβ1) to the IL2/IL15Rβ receptor, expressed on T-LGL, is explored in this trial to evaluate the safety, pharmacokinetics, specificity and clinical efficacy of Hu-Mikβ1. The study demonstrated no toxicity and favorable saturation of IL2/IL15Rβ receptor, but no clinical efficacy in this Phase I study.
IL-15 是一种细胞因子,可刺激 NK 和 T 细胞的增殖。先前的研究表明,IL-15 对诱导 T 细胞大颗粒淋巴细胞(T-LGL)白血病至关重要。本试验研究了一种针对 T-LGL 上表达的 IL2/IL15Rβ 受体的人源化抗体(Hu-Mikβ1)的 I 期临床试验,以评估 Hu-Mikβ1 的安全性、药代动力学、特异性和临床疗效。该研究表明,该试验中无毒性和 IL2/IL15Rβ 受体的良好饱和,但无临床疗效。
