4.    Grant Income

One of the Company's proprietary respiratory assets is PRS-220, an oral inhaled Anticalin protein targeting connective tissue growth factor, or CTGF, and it is being developed as a local treatment for idiopathic pulmonary fibrosis and other forms of fibrotic lung diseases. In June 2021, the Company was selected to receive a €14.2 million (approximately $17.0 million as of June 2021) grant from the Bavarian Ministry of Economic Affairs, Regional Development and Energy (the Bavarian Grant) supporting research and development for the program.

The Bavarian Grant provides partial reimbursement for qualifying research and development activities on PRS-220, including drug manufacturing costs, activities and costs to support an IND filing, and phase 1 clinical trials costs. The Bavarian Grant provides reimbursement of qualifying costs incurred through June 2023 (with submissions for reimbursements allowed through August 2023). The Company has applied for a six-month extension that would enable the Company to request reimbursement of qualifying costs incurred by December 2023 (with submission for reimbursements allowed through February 2024). The timing of reimbursements follows the expected development timeline of this program. Qualifying costs incurred may exceed the annual grant funding thresholds. If the Company receives any proceeds from the sale of or licensing income from PRS-220, the funds available for reimbursement will be reduced proportionally, if they are obtained prior to December 2023, the extended reimbursement period if the extension application is approved. In this case, the Company may also be required to refund some or all of the amounts received under the grant. The Company is required to communicate the amount of such proceeds to the Bavarian Ministry of Economic Affairs, Regional Development and Energy in each case with the request to draw down the funds. In addition, the Company is required to communicate if there is a change in control or other event that would impact the continuation of PRS-220 to the Bavarian project agency, in which case the Company may be required to refund some or all of amounts received under the grant.
