AMENDMENT #1

TO PATENT ASSIGNMENT AND LICENSING AGREEMENT

This Amendment No. 1 (“Amendment No. 1”) to the Patent Assignment and Licensing Agreement by and between Boehringer Ingelheim International GmbH (“BII”) and Centrexion Therapeutics Corporation (“CENTREXION”), dated November 11, 2015, (the “Agreement”) is entered into effective as of January 29, 2018.

WHEREAS, pursuant to the Agreement, in November 2017 CENTREXION provided BII with a progress report related to activities during the period May 2017 through November 2017 (the “November 2017 Progress Report,” attached hereto as Exhibit A); and

WHEREAS, the November 2017 Progress Report updated certain expected timelines and expected completion dates for certain milestone events set forth in the Agreement; and

WHEREAS, CENTREXION and BII (each, a “Party” and together, the “Parties”) wish to amend the Agreement by replacing the original timelines and expected milestone completion dates contained therein with the new timelines and expected milestone completion dates set forth in the November 2017 Progress Report; and

WHEREAS, the Parties wish to further amend the Agreement to set forth a practical procedure whereby they may agree upon additional, future amendments to the Agreement’s timelines and expected milestone completion dates in the event additional, future changes to such timelines or dates are required;

NOW, THEREFORE, in consideration of the mutual covenants, agreements and stipulations set forth herein and in the Agreement, the receipt and legal sufficiency of which are hereby mutually acknowledged, and intending to be legally bound, the Parties hereby agree to amend the Agreement as follows:

1. The last sentence of Section 4.2 of the Agreement shall be deleted and replaced in its entirety with the following language:

CENTREXION shall perform the Development within the timelines as set forth within the most recent Agreed Progress Report provided by CENTREXION to BII. The Parties agree and acknowledge that as of the date of Amendment No. 1 to this Agreement, the most recent Agreed Progress Report is the November 2017 Progress Report.

2. Section 4.3 of the Agreement shall be deleted and replaced in its entirety with the following language:

Development Milestones. CENTREXION shall achieve the following development milestones (“Development Milestones”):

(a) CCR2: Initiation (first patient in) of a Phase IIa Clinical Trial before the expected date for such Development Milestone consistent with the timelines set forth in the most recent Agreed Progress Report.

(b) CB2: Initiation (first patient in) of a Phase I Clinical Trial before the expected date for such Development Milestone consistent with the timelines set forth in the most recent Agreed Progress Report.

(c) SSTR4: Initiation (first patient in) of a Phase I Clinical Trial before the expected date for such Development Milestone consistent with the timelines set forth in the most recent Agreed Progress Report.

3. Section 4.4 of the Agreement shall be deleted and replaced in its entirety with the following language:

Extensions of Time. If CENTREXION is unlikely to accomplish a specific development, or commercialization-related task under this Agreement or the Development Plan, it shall inform BII thereof in its next Progress Report and shall state therein a new time line for expected accomplishment or achievement of such task or Development Milestone. Within [***] of receipt from CENTREXION of a Progress Report, BII shall inform CENTREXION in writing if BII has any objection to or concerns about any revised or restated timelines or expected completion dates for Development Milestones set forth therein. If BII does not so inform CENTREXION in writing of any objections or concerns within such timeframe, then BII shall be deemed to have agreed to any revised or restated timelines for Development Milestones as set forth in such Progress Report, and such Progress Report shall be considered an “Agreed Progress Report.” In the event BII does inform CENTREXION in writing of any objections or concerns within the [***] timeframe, the Parties will discuss and attempt to resolve in good faith BII’s objection or concerns; provided, however, that BII shall have no obligation to grant an extension of the Development Milestones specified in Section 4.3 and the most recent Agreed Progress Report. In such case, the Progress Report will only be deemed to be an “Agreed Progress Report” if both Parties thereafter expressly so agree in writing.

4. Section 6.1 of the Agreement shall be deleted and replaced in its entirety with the following language:

Development Reporting. CENTREXION shall inform BII, on an at least [***] basis, of the development activities performed in connection with the Products, any Results achieved or generated and timelines until next milestone. Each such report shall be known as a “Progress Report.” CENTREXION shall inform BII in each Progress Report of any material changes to the development including but not limited to significant delays in or changes to the timelines towards the next applicable milestone.
