标准单药非铂类化疗对铂耐药/铂难治性卵巢癌的少数患者仅提供有限获益,客观缓解率为6-20%,无进展生存期约为3-4个月。Nemvaleukin alfa(nemvaleukin,ALKS 4230)是一种新型细胞因子,旨在捕获并拓展高剂量白细胞介素-2(IL-2)的治疗潜力,同时减轻其相关毒性问题。Nemvaleukin优先激活细胞毒性CD8+ T细胞和NK 细胞,对CD4+调节性T细胞的影响极小且非剂量依赖性。全球性、随机、开放标签、III期ARTISTRY-7试验将比较nemvaleukin联合pembrolizumab与化疗在铂耐药卵巢癌患者中的疗效和安全性。主要终点为研究者评估的无进展生存期。临床试验注册:GOG-3063;ENGOT-OV68;NCT05092360(ClinicalTrials.gov)。在许多接受铂类化疗的卵巢癌患者中,肿瘤在几个月后复发,并对重复治疗无反应。这种类型的疾病称为铂耐药卵巢癌(PROC)。研究人员正在寻找新药以帮助更多PROC患者。
一种在不同癌症中显示出前景的治疗方法称为免疫治疗。这些药物通过帮助机体免疫系统攻击癌细胞发挥作用。正在研究的一种免疫治疗药物称为nemvaleukin。它旨在触发特定的免疫反应,可能使免疫系统攻击癌细胞,同时可能避免其他可能阻断攻击或导致某些不良副作用的免疫反应。Nemvaleukin 正在多种癌症类型中接受研究。在一项名为 ARTISTRY-7 的全球临床试验中,研究人员正在探索 nemvaleukin 与另一种称为 pembrolizumab 的免疫疗法联合用于 PROC 患者时的作用。参与该试验的患者将被随机分配到四个治疗组之一:nemvaleukin 与 pembrolizumab 联合、nemvaleukin 单药、pembrolizumab 单药,或由治疗医生选择的一种化疗。ARTISTRY-7 的主要目的是了解 nemvaleukin 与 pembrolizumab 联合是否有助于 PROC 患者在不发生癌症恶化的情况下活得更久。在撰写本文时,ARTISTRY-7 正在开放招募新患者。
Standard single-agent nonplatinum chemotherapy provides only modest benefit in a small proportion of patients with platinum-resistant/-refractory ovarian cancer, with objective response rates of 6-20% and progression-free survival of ≈3-4 months. Nemvaleukin alfa (nemvaleukin, ALKS 4230) is a novel cytokine designed to capture and expand the therapeutic potential of high-dose interleukin-2 (IL-2) while mitigating its associated toxicity issues. Nemvaleukin preferentially activates cytotoxic CD8 + T cells and natural killer cells with minimal, non-dose-dependent effects on CD4 + regulatory T cells. The global, randomized, open-label, phase III ARTISTRY-7 trial will compare efficacy and safety of nemvaleukin plus pembrolizumab with chemotherapy in patients with platinum-resistant ovarian cancer. The primary end point is investigator-assessed progression-free survival. Clinical Trial Registration : GOG-3063; ENGOT-OV68; NCT05092360 (ClinicalTrials. gov). In many patients with ovarian cancer who are treated with platinum-based chemotherapy, the tumor comes back after a few months and fails to respond to repeated treatment. This type of disease is called platinum-resistant ovarian cancer (PROC). Researchers are searching for new medicines to help more patients with PROC.
One treatment approach that has shown promise in different cancers is called immunotherapy. These medicines work by helping the body's immune system attack cancer cells. One of the immunotherapies being studied is called nemvaleukin. It is designed to trigger specific immune responses that may result in the immune system attacking cancer cells while potentially avoiding other immune responses that can block the attack or cause certain unwanted side effects. Nemvaleukin is being studied in a variety of cancer types.
In a worldwide clinical trial called ARTISTRY-7, researchers are investigating how nemvaleukin works in patients with PROC when given with another immunotherapy called pembrolizumab. Patients who participate in this trial will be randomly assigned to one of four treatment groups: the combination of nemvaleukin and pembrolizumab, nemvaleukin by itself, pembrolizumab by itself, or a type of chemotherapy selected by the treating physician.
The main purpose of ARTISTRY-7 is to understand whether the combination of nemvaleukin and pembrolizumab helps patients with PROC live longer without their cancer getting worse. At the time of this writing, ARTISTRY-7 is open for new patients to join.
