项目摘要

DESCRIPTION (provided by applicant): SBIR Phase I proposal to NIH requests $183,000 funding for Chromatan, Inc. to demonstrate the feasibility of using Continuous Countercurrent Tangential Chromatography (CCTC) for the purification of high value biological products, e.g., monoclonal antibodies for the treatment of cancer or recombinant vaccines for protection against viral disease or a flu pandemic. Downstream processing currently accounts for as much as 80% of the overall cost of production of recombinant protein products. Recent advances in cell culture technology have created a "downstream bottleneck" due to the limited capacity and high expense of packed bed chromatography columns. CCTC overcomes many of the limitations of conventional column chromatography by using resin particles in the form of a slurry, which is pumped through a disposable flow path consisting of a series of static mixers and hollow fiber membrane modules. Countercurrent recycling of the permeate is used to significantly increase process efficiency and reduce resin and buffer requirements, analogous to the behavior in countercurrent liquid-liquid extraction. The optimal membrane pore size, resin particle size, and operating conditions for CCTC (e.g. crossflow rate, permeate flow rate, and residence time in the static mixers) will be determined from experimental measurements of the critical filtrate flux and the binding / elution kinetics. CCTC can employ much smaller resin particles than packed bed columns, since there is no longer any pressure drop limitation, which can provide significantly faster mass transfer rates. The overall goal of the proposed research is to design, construct, and test a prototype CCTC system capable of separating a model protein mixture with greater than 90% product yield and 95% purity. Chromatan envisions that CCTC technology will provide the following favorable impacts for large-scale commercial applications of chromatography: 5-fold reduction in resin volume requirements compared with column chromatography; a disposable flow path that eliminates the need for costly cleaning validation; straightforward scalability up to batch volumes of 20,000 L; significant reduction of capital costs (up to 60%) in large-scale operations; significant overall cost savings (up to 75%) for capture chromatography steps. The continuous and disposable nature of this technology will improve public health by decreasing time to market and reducing production costs, both of which will lead to a reduction in drug costs. Chromatan projects a fifth year market peneratraion of 10% and revenues of $100 million. PUBLIC HEALTH RELEVANCE: The overall goal of the proposed SBIR project is to design, construct, and test a Continuous Countercurrent Tangential Chromatography system capable of providing highly efficient and low cost purification of therapeutic proteins and vaccines. CCTC is designed to have a disposable flow path, continuous operation, and lower capital and operating costs compared to current separation technologies, and will lead to significant improvements in public health by reducing the cost of important drug products, and by decreasing the time required to bring new therapeutic drugs to market.
描述(由申请人提供):SBIR I期提案向NIH申请183,000美元资金,用于色谱公司证明使用连续逆流切向色谱(CCTC)纯化高价值生物制品的可行性,例如用于治疗癌症的单克隆抗体或用于预防病毒疾病或流感大流行的重组疫苗。下游加工目前占重组蛋白产品生产总成本的80%。由于填充床色谱柱的容量有限和费用高昂,细胞培养技术的最新进展造成了“下游瓶颈”。CCTC通过将树脂颗粒以浆液的形式泵入由一系列静态混合器和中空纤维膜模块组成的一次性流道,克服了传统柱色谱法的许多局限性。渗透液的逆流回收用于显著提高工艺效率,减少树脂和缓冲液的需求,类似于逆流液-液萃取。最佳的膜孔径、树脂粒度和CCTC的操作条件(如横流速率、渗透速率和在静态混合器中的停留时间)将通过临界滤液通量和结合/洗脱动力学的实验测量来确定。CCTC可以使用比填充床柱小得多的树脂颗粒,因为不再有压降限制,这可以提供显着更快的传质速率。拟议研究的总体目标是设计、构建和测试一个原型CCTC系统,该系统能够分离模型蛋白质混合物,产品收率大于90%,纯度为95%。色谱公司认为,CCTC技术将为色谱的大规模商业应用带来以下有利影响:与柱色谱相比,树脂体积需求减少5倍;一次性流动路径,无需昂贵的清洁验证;可直接扩展到批量容量为20,000 L;在大规模作业中显著降低资本成本(高达60%);捕获色谱步骤显著节省总体成本(高达75%)。这种技术的连续性和一次性性质将通过缩短上市时间和降低生产成本来改善公众健康,这两者都将导致药品成本的降低。该公司预计,这款产品的市场渗透率将在第五年达到10%,收入将达到1亿美元。
