What changed since the prior 10-K
New
- NewRisks related to financial position and need for capital
add operational, financial and management information systems and personnel
We require substantial additional funding to support operations and growth, and failing to raise capital or enter strategic agreements will force us to delay or eliminate product development.
- NewRisks related to regulatory, legal, and clinical trials
proprietary, personal or confidential information or other disruptions. For example, the loss of clinical trial data from future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data
Loss of clinical trial data from future trials due to cybersecurity incidents could delay regulatory approval efforts and significantly increase our recovery costs.
- NewRisks related to third-party relationships
independently. This would increase our reliance on such third-party manufacturer or require us to obtain a license from such third-party manufacturer in order to have another third party manufacture our product candidates
Reliance on a limited number of third-party contract manufacturers, some located in China, exposes us to supply chain disruptions and increased tariffs between the US and other countries.
- NewGeneral risks
on climate change and human rights, ethics and compliance with law, and the role of the company’s board of directors in supervising various sustainability issues
Potential requirements to make significant investments in ESG matters could damage our reputation, expose us to regulatory risk, and harm our business and share value.
Dropped
- DroppedRisks related to financial position and need for capital
incur additional legal, audit, accounting, compliance, insurance, investor relations and other expenses to continue to operate as a public company that we did not incur as a private company
- DroppedRisks related to regulatory, legal, and clinical trials
the approval policies or regulations of the FDA or comparable foreign regulatory authorities may significantly change in a manner rendering our clinical data insufficient for approval

- 79If we are sued for infringing intellectual property rights of third parties, such litigation could be costly and time consuming and could prevent or delay us from developing or commercializing our product candidates
- 80Others may challenge inventorship or claim an ownership interest in our intellectual property which could expose it to litigation and have a significant adverse effect on its prospects
- 81We may be subject to claims that we have wrongfully hired an employee from a competitor or by third parties asserting that our employees or we have misappropriated their intellectual property or claiming ownership of what we regard as our own intellectual property

It may be necessary for us to use the patented or proprietary technology of one or more third parties to commercialize our current and future product candidates
- 84If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates
