In August 2019, the Company executed a Share Exchange Agreement with Relief Holdings, in which the Company agreed to acquire the outstanding shares of Relief. The Company issued 757,933 shares of common stock upon closing of the transaction on April 1, 2020.

For accounting purposes, the Company determined that the acquisition of Relief did not meet the definition of a business and was accounted for as an asset acquisition since substantially all of the fair value of the assets acquired was concentrated in a single identified intangible asset, atexakin alfa.

The Company expensed the acquired IPR&D as of the acquisition date since further development and regulatory approval are required.
