Note: Schedules filed in paper format shall include a signed original and five copies of the schedule, including all exhibits. See §240.13d-7 for other parties to whom copies are to be sent.

The information required on the remainder of this cover page shall not be deemed to be “filed” for the purpose of section 18 of the Securities Exchange Act of 1934, as amended (the “Act”) or otherwise subject to the liabilities of that section of the Act but shall be subject to all other provisions of the Act (however, see the Notes).

Item 1. Security and Issuer.

This Amendment No. 4 amends the statement on Schedule 13D originally filed with the SEC on May 24, 2019, as amended by Amendment No. 1 to Schedule 13D filed with the SEC on January 31, 2020, Amendment No. 2 to Schedule 13D filed with the SEC on March 2, 2021, and Amendment No. 3 to Schedule 13D filed with the SEC on June 15, 2023 (together, this “Schedule 13D”). This Schedule 13D relates to the common stock, par value $0.01 per share (the “Common Stock”), of ClearPoint Neuro, Inc., a Delaware corporation (the “Issuer”). The address of the Issuer’s principal executive office is 120 S. Sierra Ave., Suite 100, Solana Beach, California 92075.

PTC Therapeutics, Inc., a Delaware corporation (“PTC”), is filing this Amendment No. 4 to the Schedule 13D to report the decrease in the percentage of the Common Stock of the Issuer beneficially owned by PTC due to the repayment of a senior secured convertible note on August 23, 2024 having a principal amount of $10,000,000 (the “PTC Note”), which PTC Note was previously acquired by PTC as previously reported on January 31, 2020, subject to adjustment as provided in the PTC Note.

As a result of the repayment of the PTC Note described herein, on August 23, 2024, PTC ceased to be the beneficial owner of more than five percent of the Issuer’s outstanding Common Stock. The filing of this Amendment No. 4 represents the final amendment to this Schedule 13D and constitutes an exit filing for PTC.

Item 2 of the Schedule 13D is hereby amended as follows:

The principal business address of PTC is 500 Warren Corporate Center Drive, Warren, NJ 07059.

Item 3 of the Schedule 13D is hereby amended as follows:

On August 23, 2024, the outstanding principal amount of the PTC Note, together with any accrued and unpaid interest thereon, was repaid in full by the Issuer and the PTC Note was cancelled. As a result, PTC is no longer the beneficial owner of 1,666,667 shares of Common Stock of the Issuer, which represented the maximum number of shares of Common Stock of the Issuer that could be issued to PTC in connection with the conversion of the PTC Note.
