 biotechnology companies, and others in Congress have advocated for the use of existing executive branch authorities to limit those Chinese service providers’ ability to engage in business in the U.S. We cannot predict what actions may ultimately be taken with respect to trade relations between the United States and China or other countries, what products and services may be subject to such actions or what actions may be taken by the other countries in retaliation. If we are unable to obtain or use services from existing service providers or become unable to export or sell our products to any of our customers or service providers, our business, liquidity, financial condition, and/or results of operations would be materially and adversely affected.

Risks Related to Our Reliance on Third Parties

Our product candidates are complex and can be difficult to manufacture.

Our product candidates are complex and can be difficult to manufacture due to the advanced linker-payload architecture. Problems with the manufacturing process, including even minor deviations from the normal process, could result in product defects or manufacturing failures that result in lot failures, product recalls, product liability claims, and insufficient inventory, negative impact on our sales and results of operations and make us a less attractive collaborator for potential partners or subject us to liability for any contamination or injury or failure to comply with applicable laws. We may encounter problems achieving adequate quantities and quality of clinical-grade materials that meet FDA, EMA or other applicable standards or specifications with consistent and acceptable production yields and costs.  There can be no assurance that manufacturing issues will not occur in the future.

We are currently dependent on single-source suppliers for our product candidates and their components, any issues with any such suppliers, including increases in costs or expenses or delays in supply, could harm our business.

We currently rely on third parties to manufacture or supply our product candidates and their components and raw materials, many of which are sole source manufacturers and suppliers. For the near term, Hangzhou DAC will continue to manufacture the CPT113 linker-payload and WuXi Biologics will continue to manufacture the antibodies underlying our ADC product candidates. A subsidiary of WuXi Biologics will carry forward majority of the IND-enabling CMC, including antibody development, bioconjugation and fill and finish.

Although we have arrangements in place for the manufacture and supply of our product candidates and its key components, our manufacturers or suppliers could discontinue the manufacturing or supply at any time. Our manufacturers or suppliers may not be able to meet our demand whether because of acts of nature, the nature of our agreements with those manufacturers or suppliers or our relative importance to
