(“Paragon”). Prior to the Amendment, the Company’s Field did not include inflammatory bowel disease. The Amendment, among other things, expands the definition of “Field” to encompass all therapeutic, prophylactic, palliative and diagnostic uses, subject to the restriction that the Company will not dose a human patient in a clinical trial of ORKA-001 for inflammatory bowel disease as part of a combination until June 1, 2028 or as a monotherapy until June 1, 2030 (the “Monotherapy Dosing Restriction”). In the event the Company or a licensee of Paragon’s retained rights under the License Agreement consummates a material transaction, including a change of control of the Company or such licensee, then any remaining restrictions outside of the initial definition of “Field” set forth in the Monotherapy Dosing Restriction shall remain in effect only until June 1, 2028 and thereafter terminate and be of no further force or effect.

     

    The foregoing is a brief description of the terms and conditions of the Amendment and do not purport to be complete. The description is qualified in its entirety by reference to the complete text of the Amendment, a copy of which is attached hereto as Exhibit 10.1.
