Centrexion Therapeutics Corporation:

We consent to the use of our report included herein and to the reference to our firm under the heading “Experts” in the prospectus. Our report dated September 10, 2018, except for Note 16, as to which the date is November 5, 2018, contains an explanatory paragraph that states that the Company has incurred operating losses and negative cash flows from operations since inception, which raise substantial doubt about its ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of that uncertainty.
