 FDA grants Orphan Drug Designation, the identity of the drug or biological product and its potential orphan use are disclosed publicly by the FDA. Orphan Drug Designation does not convey any advantage in, or shorten the duration of, the regulatory review and licensure process.

If a product that has Orphan Drug Designation subsequently receives the first FDA approval or licensure for a particular active ingredient for the disease for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications, including an NDA or BLA, to market the same drug or biological product for the same indication for seven years, except in limited circumstances such as a showing of clinical superiority to the product with orphan drug exclusivity or if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the biological product was designated. As a result, even if one of Kineta’s product candidates receives orphan exclusivity, the FDA can still approve or license other drugs or biological products that have a different active ingredient for use in treating the same indication or disease. Further, the FDA can waive orphan exclusivity if Kineta is unable to manufacture sufficient supply of its product.**

**Kineta may seek Orphan Drug Designation for its product candidates in additional orphan indications in which there is a medically plausible basis for the use of these product candidates. Even when Kineta obtains Orphan Drug Designation, exclusive marketing rights in the United States may be limited if Kineta seeks licensure for an indication broader than the orphan designated indication and may be lost if the FDA later determines that the request for designation was materially defective or if Kineta, through its manufacturer, is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition. In addition, although Kineta intends to seek Orphan Drug Designation for other product candidates, Kineta may never receive these designations.

If Kineta fails to develop additional product candidates, its commercial opportunity could be limited.

Kineta expects initially to focus on the development of KVA12123, its lead immuno-oncology drug candidate. A key part of Kineta’s strategy, however, is to continue to pursue clinical development of additional product candidates utilizing its development platform or in-licensed from third parties.
