The risks most specific to Zenas BioPharma

  • Risks Related to Our Financial Position and Need for Capital

    We are a clinical stage biopharma company with a limited operating history and no products approved for commercial sale; we have incurred substantial losses since our inception, and we anticipate incurring substantial and increasing losses for the foreseeable future

    We are a clinical-stage biopharma company with no approved products, no commercial revenue, and a history of substantial operating losses.

  • Risks Related to Our Financial Position and Need for Capital

    We will require substantial additional financing to achieve our goals, and failure to obtain additional capital when needed, or on acceptable terms, would cause us to delay, limit, reduce or terminate our product development efforts

    We require substantial additional financing to fund preclinical studies and clinical trials, and failure to obtain capital will halt development.

  • Risks Related to Product Candidate Development and Commercialization

    Risks associated with the in-licensing or acquisition of product candidates could cause substantial delays in the preclinical and clinical development of our product candidates

    We rely heavily on licensing partners, such as Xencor, for research, development, and accurate reporting of clinical trial results for acquired product candidates.

  • Risks Related to Product Candidate Development and Commercialization

    Our ongoing Phase 3 trial of obexelimab for IgG4-RD and other clinical trials of obexelimab, even if successfully completed, may not be sufficient for approval of obexelimab for the applicable indication

    Our ongoing Phase 3 trial of obexelimab for IgG4-RD and other trials may not be sufficient for regulatory approval.

  • Risks Related to Product Candidate Development and Commercialization

    We may expend our limited resources to pursue a particular product candidate in specific indications and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success

    We focus our limited resources on lead candidate obexelimab for IgG4-RD, MS, and SLE, risking failure if these indications underperform.

  • Risks Related to Our Business and Operations

    We are dependent on the services of our senior management and other clinical and scientific personnel, and if we are not able to retain these individuals or recruit additional management or clinical and scientific personnel, our business will suffer

    We depend heavily on our Founder and CEO, Leon O. Moulder, Jr., and other senior management and scientific personnel.

  • Risks Related to Our Intellectual Property

    We have in-licensed patent portfolios, but have no solely owned issued patents relating to our product candidates
