`
`Additional Information - Product Updates
`
`Inmazeb
`
`Inmazeb is a cocktail of three fully human monoclonal antibodies that each bind to the Ebola virus at different points, which may serve to increase efficacy,
`reduce the development of viral sequences that lead to resistance, and potentially enable utility in future outbreaks as viruses continue to evolve. In October
`2020, the U.S. Food and Drug Administration ("FDA") approved Inmazeb for the treatment of infection caused by Zaire ebolavirus in adult and pediatric
`patients, including newborns of mothers who have tested positive for the infection. In connection with this approval, we were also granted a material threat
`medical countermeasure priority review voucher by the FDA.
`
`REGEN-COV - Emergency Use Authorization
`In November 2020, REGEN-COV (antibody cocktail casirivimab and imdevimab administered together) received Emergency Use Authorization ("EUA")
`from the FDA for the treatment of mild to moderate COVID-19 in adults, as well as in pediatric patients at least 12 years of age and weighing at least 40
`kg, who have received positive results of direct SARS-CoV-2 viral testing and are

`at high risk for progressing to severe COVID-19 and/or hospitalization. The EUA is temporary and does not replace a formal Biologics License
`Application ("BLA") submission review and approval process. This use is authorized only for the duration of the declaration that circumstances exist
`justifying the authorization of the emergency use, unless terminated or revoked sooner. See information regarding ongoing clinical trials of REGEN-COV

`
`Programs in Clinical Development
`
`Product candidates in clinical development, which are being developed by us and/or our collaborators, are summarized in the table below. We believe that
`®
`our ability to develop product candidates is enhanced by the application of our VelociSuite technology platforms (refer to "Research and Development
`Technologies - VelociSuite" section below). We continue to invest in the development of enabling technologies to assist in our efforts to identify, develop,
`manufacture, and commercialize new product candidates.
`
`There are numerous uncertainties associated with drug development, including uncertainties related to safety and efficacy data from each phase of drug
`development (including any post-approval studies), uncertainties related to the enrollment and performance of clinical trials, changes in regulatory
`requirements, changes to drug pricing and reimbursement regulations and requirements, and changes in the competitive landscape affecting a product
`candidate. The planning, execution, and results of our clinical programs are significant factors that can affect our operating and financial results.
`
`We and our collaborators conduct clinical trials in multiple countries across the world. The COVID-19 pandemic and the restrictions adopted around the
`globe to reduce the spread of the disease have impacted and will continue to impact our clinical development programs. We continue to evaluate the impact
`of the COVID-19 pandemic on an individual trial basis and oversee trial management while also working to ensure patient safety and provide sufficient
`supply of product candidates for the studies. At this time, we expect fully enrolled clinical studies to remain generally on track. However, the ongoing
`pandemic continues to impact clinical trial execution in many regions across the world for us and our collaborators. The ultimate impact (including possible
`delays in recruiting and/or obtaining data) resulting from the COVID-19 pandemic will depend, among other factors, on the extent of the pandemic in the
`areas with study sites and patient populations. It is possible that the COVID-19 pandemic may cause clinical disruptions beyond those we have described.
`In addition, there may be delays in the timing of regulatory review and other projected milestones discussed in the table below.
