The company has incurred significant losses since inception, with an accumulated deficit of **$257.3 million** as of June 30, 2020, and anticipates continued losses for the foreseeable future[121](index=121&type=chunk) - The company will likely need to raise substantial additional capital to complete clinical development and commercialization, and failure to do so could force delays or termination of development efforts[128](index=128&type=chunk)[129](index=129&type=chunk) - Global economic disruptions, including the COVID-19 pandemic, could adversely affect the company's ability to secure necessary financing on favorable terms[135](index=135&type=chunk) [Risks Related to Business](index=31&type=section&id=Risks%20Related%20to%20Our%20Business) Business risks include potential product development failure, intense competition, lack of late-stage development and commercialization experience, COVID-19 disruptions, and adverse tax consequences from potential PFIC status - The company faces substantial competition from major pharmaceutical and biotechnology companies with greater financial resources and expertise[141](index=141&type=chunk)[143](index=143&type=chunk) - The COVID-19 pandemic may materially and adversely affect business, including supply chain disruptions and delays in clinical trials, with a significant reduction in new patient enrollment for its Phase 2b XEN1101 trial already experienced[167](index=167&type=chunk)[168](index=168&type=chunk) - The company has no experience in Phase 3 clinical development or commercialization, making it difficult to assess its ability to execute its strategy for independent product development[149](index=149&type=chunk) - There is a risk that the company could be characterized as a passive foreign investment company (PFIC) for U.S. federal income tax purposes, which could result in adverse tax consequences for U.S. shareholders[172](index=172&type=chunk) [Risks Related to Development, Clinical Testing and Regulatory Approval](index=38&type=section&id=Risks%20Related%20to%20Development%2C%20Clinical%20Testing%20and%20Regulatory%20Approval%20of%20Our%20Product%20Candidates) Regulatory approval is lengthy and unpredictable, with clinical trials facing delays, enrollment challenges, and non-predictive early-stage results, alongside risks in obtaining and maintaining orphan drug designation - The regulatory approval process is lengthy, time-consuming, and inherently unpredictable, and there is no guarantee that any product candidates will receive approval[182](index=182&type=chunk) - Clinical trials can be delayed for many reasons, including inability to enroll sufficient patients, particularly for orphan diseases, with the COVID-19 pandemic already causing a significant reduction in enrollment for the XEN1101 trial[186](index=186&type=chunk)[196](index=196&type=chunk) - Results of pre-clinical studies and early clinical trials are not necessarily predictive of the results of later-stage trials[203](index=203&type=chunk) - The company may fail to obtain or maintain orphan drug designation for its product candidates, which would harm its competitive position by removing market exclusivity protections[200](index=200&type=chunk) [Risks Related to Commercialization](index=43&type=section&id=Risks%20Related%20to%20Commercialization) The company lacks commercialization infrastructure, facing challenges in sales, marketing, and distribution, along with ongoing regulatory obligations, pricing pressures, reimbursement hurdles, and potential negative impacts from healthcare legislation - The company has no sales, marketing, or distribution experience and would need to build this infrastructure or rely on partners to commercialize products, which carries significant risks and costs[211](index=211&type=chunk)[212](index=212&type=chunk) - The ability to successfully commercialize products depends on obtaining adequate coverage and reimbursement from government and third-party payers, which is uncertain and subject to cost-containment pressures[220](index=220&type=chunk) - Future legislation and regulatory proposals in the U.S. and other jurisdictions aimed at controlling healthcare costs could increase the difficulty and cost of commercialization and negatively affect product prices[224](index=224&type=chunk)[226](index=226&type=chunk) [Risks Related to Dependence on Third Parties](index=47&type=section&id=Risks%20Related%20to%20Our%20Dependence%20on%20Third%20Parties) Xenon's success heavily depends on third-party collaborators for partnered asset development and commercialization, and on CMOs and CROs for manufacturing and clinical trials, posing risks to quality, compliance, and timelines - The company is dependent on collaborators like Neurocrine Biosciences to fund and conduct research, clinical development, and commercialization of partnered product candidates, and has no control over the resources they devote[232](index=232&type=chunk)[235](index=235&type=chunk) - The company relies on third-party manufacturers (CMOs) for clinical product supplies and does not own or operate manufacturing facilities, creating risks related to regulatory compliance (cGMP), quality control, and supply chain continuity[242](index=242&type=chunk)[243](index=243&type=chunk) - The company depends on third-party CROs to monitor and conduct clinical trials, and any failure by these CROs to perform as required could delay trials or compromise data integrity[244](index=244&type=chunk)[245](index=245&type=chunk)[246](index=246&type=chunk) [Risks Related to Intellectual Property](index=51&type=section&id=Risks%20Related%20to%20Intellectual%20Property) Commercial success depends on obtaining and maintaining patent protection, which is uncertain and subject to challenges, third-party infringement claims, and less extensive foreign protection, with collaborators controlling IP for partnered programs - The company's ability to obtain and maintain patent protection is uncertain and critical to its success; patents may not be issued or could be found invalid or unenforceable if challenged[252](index=252&type=chunk) - The company may face costly litigation if third parties claim that its products infringe their patent rights, which could result in substantial damages or prevent commercialization[268](index=268&type=chunk)[270](index=270&type=chunk) - For partnered products, the prosecution and enforcement of related patents are controlled by collaborators (e.g., Neurocrine Biosciences for NBI-921352), and their failure to protect this IP could adversely affect the company[263](index=263&type=chunk) - Protecting intellectual property rights in foreign jurisdictions can be difficult and less effective than in the U.S., potentially allowing competitors to use the company's technologies in those markets[257](index=257&type=chunk)[258](index=258&type=chunk) [Risks Related to Our Industry](index=56&type=section&id=Risks%20Related%20to%20Our%20Industry) The company faces inherent industry risks including product liability lawsuits, complex healthcare regulations with potential penalties for non-compliance, and environmental and safety compliance risks from hazardous materials in R&D - The company faces an inherent risk of product liability lawsuits from the clinical testing and potential commercialization of its product candidates, which could result in substantial liabilities[283](index=283&type=chunk) - Operations are subject to extensive federal and state healthcare laws, including anti-kickback and false claims statutes, and violations could lead to criminal sanctions, civil penalties, and exclusion from government healthcare programs[287](index=287&type=chunk)[289](index=289&type=chunk)[290](index=290&type=chunk) [Risks Related to the Securities Markets and Ownership of Our Common Shares](index=58&type=section&id=Risks%20Related%20to%20the%20Securities%20Markets%20and%20Ownership%20of%20Our%20Common%20Shares) Shareholders face risks including stock price volatility, dilution from future share sales, difficulties in potential acquisitions due to corporate provisions and Canadian law, challenges for U.S. investors to enforce civil liabilities, and considerations related to the company's reporting status - The market price of the company's common shares has been and is likely to be volatile, influenced by clinical trial results, regulatory decisions, and broad market fluctuations[293](index=293&type=chunk) - Future sales of common shares, including through its at-the-market equity program, could cause significant dilution to existing shareholders and cause the market price to fall[295](index=295&type=chunk)[296](index=296&type=chunk)[310](index=310&type=chunk) - As a Canadian corporation, it may be difficult for U.S. investors to enforce U.S. civil liability judgments against the company, its directors, or its officers[299](index=299&type=chunk) - The company does not anticipate paying any cash dividends in the foreseeable future, so capital appreciation may be the sole source of gain for investors[317](index=317&type=chunk) [Exhibits](index=64&type=section&id=Item%206.%20Exhibits) This section lists exhibits filed with the Form 10-Q, including the Amended and Restated 2014 Equity Incentive Plan, an amendment to an asset purchase agreement, and CEO/CFO certifications -
