Words such as “will,” “expect,” “intend,” “plan,” “potential,” “possible,” “goals,” “accelerate,” “continue,” and similar expressions identify forward-looking statements, including, without limitation, statements regarding the sufficiency of the data from the ACTIV-5/BET-B study to warrant a future submission of a new EUA request; statements regarding the Company’s efforts to request and receive Marketing Authorization or Conditional Marketing Authorization for lenzilumab in COVID-19 in the U.K. and other territories; the Company’s expectations for the duration and severity of COVID-19 in the United States and around the world and its projections for COVID-19 hospitalizations in 2021 and future years; the Company’s projections regarding the need for lenzilumab as a therapeutic if authorized or approved; the commercial potential of lenzilumab and the Company’s ability to maintain a single worldwide price in the multiple jurisdictions in which it is seeking marketing authorizations or approvals or otherwise working to sell product prior to formal approvals; and the Company’s other plans to initiate or participate in planned clinical trials and otherwise explore the effectiveness of lenzilumab and other candidates in its development portfolio as therapies for other inflammation and immune-oncology indications. These forward-looking statements are subject to a number of risks and uncertainties including, but not limited to, the risks inherent in the Company’s lack of profitability and need for additional capital to grow its business; the Company’s dependence on partners to further the development of its product candidates; the uncertainties inherent in the development, attainment of the requisite regulatory authorization and approvals and launch of any new pharmaceutical product; the outcome of pending or future litigation; and the various risks and uncertainties described in the “Risk Factors” sections and elsewhere in the Humanigen's periodic and other filings with the Securities and Exchange Commission.
