Therapeutic antibodies have had a profound impact on treatment of many types of cancer and autoimmune diseases with many new therapeutics in development. However, antibodies are extremely expensive to produce, and large amounts of antibody are required to achieve clinical efficacy. In our 268 interviews with industry experts and extensive research of the literature, Protein A-based purification is the largest pain point in mAb manufacturing. The Protein A market was $600 million in 2019 and is projected to grow to over $1 billion by 2026. This market can be divided into the classical resins that have dominated the market and new alternatives which include membranes. There is a strong desire to move away from resins; however, a lack of alternatives with superior performance have prevented this. Our Phase I data demonstrate that we have considerable advantages over incumbent suppliers by providing a high binding capacity, high-flow, single-use membrane that doesn’t rely on crosslinking. At the end of Phase II, we will produce our minimally viable product: a low-cost, high-capacity, single-use antibody purification membrane that has been validated by key industry players and ready to be displayed internationally. To do this we will accomplish the following Aims: 1) Industrial Scale Production of protein monomers 2) Optimize efficiency of electrospun membrane 3) Testing with Industry Partners. The slow adoption rate of new technologies, preference for brand reputation, compliance with FDA SOPs, global supply risk, and long runway to revenue lead to start-ups similar to ours being acquired before any sales occur. Therefore, our goal is not to manufacture and sell this product but to pursue an early exit through licensing, partnership with, or acquisition by, established companies. To accomplish this, we will leverage the data generated from industry partners during this Phase II proposal to generate high profile scientific publications and presentations at leading conferences.

治疗性抗体对许多类型的癌症的治疗具有深远的影响， 自身免疫性疾病，许多新疗法正在开发中。然而，抗体 生产极其昂贵，并且需要大量的抗体来实现临床应用。 功效在我们对行业专家的268次采访和对文献的广泛研究中， 基于蛋白A的纯化是mAb生产中最大的痛点。蛋白质A市场 2019年为6亿美元，预计到2026年将增长到10亿美元以上。这个市场可以 分为主导市场的经典树脂和新的替代品， 包括膜。人们强烈希望摆脱树脂;然而，缺乏 具有上级性能的替代物防止了这种情况。我们的第一阶段数据表明， 我们通过提供高的结合能力而比现有供应商具有相当大的优势， 高流动性，一次性使用的膜，不依赖于交联。在第二阶段结束时，我们将 生产我们的最低可行性产品：低成本，高容量，一次性抗体纯化 膜已被主要行业参与者验证，并准备展示 化国际大为此，我们将实现以下目标：1）工业规模生产 蛋白质单体2）优化电纺膜的效率3）工业测试 伙伴新技术采用速度缓慢，对品牌声誉的偏好， 遵守FDA SOP、全球供应风险和长期收益导致初创企业 就像我们在出售之前被收购一样因此，我们的目标不是制造 并销售此产品，但通过许可、合作或收购来寻求提前退出 ，建立公司。为了实现这一目标，我们将利用行业产生的数据， 在第二阶段提案期间，合作伙伴将产生高知名度的科学出版物， 在主要会议上发言。
