Item 7.01. Regulation FD Disclosure.

On October 10, 2023, Orchestra BioMed Holdings, Inc. (the “Company,” “we,” or “our”) filed a registration statement on Form S-1 (the “Registration Statement”) to register under the Securities Act of 1933, as amended, the resale of certain shares of its common stock, par value $0.0001 per share (“Common Stock”), the resale of certain warrants to purchase Common Stock and the issuance of certain shares of Common Stock underlying warrants, as required by the terms of the Amended and Restated Registration Rights and Lock-Up Agreement it entered into on January 26, 2023 with certain investors. The Company did not file the Registration Statement as part of an effort to raise capital and is not seeking to raise additional capital at this time.

The Registration Statement includes, among other things, the following updated information:

As previously disclosed, the Company, on the one hand, and Terumo Corporation and its U.S. subsidiary, Terumo Medical Corporation (collectively, “Terumo”), on the other hand, have been negotiating mutually agreeable adjustments to the Company’s distribution agreement with Terumo (the “Terumo Agreement”) that could serve to restructure milestone payments as well as make other potential material modifications to the Terumo Agreement. Until we gain clarity on the likely outcome of such ongoing negotiations, our current expectation is that the initiation of the Virtue ISR-US pivotal study evaluating the efficacy and safety of our Virtue Sirolimus AngioInfusion Balloon (“Virtue SAB”) will be postponed until 2024. If negotiations are not completed to our satisfaction or to the satisfaction of Terumo, clinical study, product development, and commercialization plans for Virtue SAB may continue to be adversely impacted.

An updated copy of the slide presentation that the Company uses at investor and industry conferences and presentations is attached to this Current Report on Form 8-K (this “Current Report”) as Exhibit 99.1 and is incorporated herein solely for purposes of this Item 7.01 disclosure.

The information in Item 7.01 of this Current Report, including Exhibit 99.1 attached hereto, is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of such section. The information in Item 7.01 of this Current Report, including Exhibit 99.1, shall not be incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any incorporation by reference language in any such filing.

Advancing High - Impact Pipeline 1 Plan to leverage existing coronary ISR data to support potential Pivotal Study, although there have only been limited discussions with the FDA or a comparable foreign regulator in this regard. 2 Will seek to leverage data from HTN+P pilot and pivotal trials to support clinical and regulatory development for High - Risk HTN indication given that age and other demographic factors of the target population are expected to be similar, the type of hypertension treated will likely be isol ate d systolic hypertension which is predominant in the HTN+P population, and other co - morbidities are also expected to be common to both target populations. However, there have been no discussions with the FDA or a comparable foreign regulator in this regard. 3 Virtue SAB has received Breakthrough Device Designation for the balloon dilatation of the stenotic portion (up to 26 mm length) of a stented coronary artery (in - stent restenosis (ISR)) that is 2.25 to 4.0 mm in diameter, for the purpose of improving lumen diameter; 4 Virtue SAB has received Breakthrough Device Designation for the balloon dilatation of the de novo stenotic portion (up to 26mm in lesion length) of a native coronary artery of 2.0 mm to 2.5 mm in diameter (sm all coronary arteries), for the purpose of improving lumen diameter; 5 Virtue SAB has received Breakthrough Device Designation for the balloon dilatation of the stenotic portion (up to 18 mm length) of an infrapopliteal artery (P - 3 segment or distal, below the knee, with reference vessel diameter (RVD) 2.25 - 4.0 mm), for the purpose of improvi ng lumen diameter. All references to clinical study initiations for HTN+P, Coronary ISR and Coronary SV indications are based on ongoing interac tio ns with US FDA regarding IDE approvals or Japan PMDA regarding CTN approvals, which are required to start clinical studies. With respect to BackBeat CNT for HTN, Orchestra and Medtronic have had initial interactions with the FDA regarding IDE approval and expect to continue i nteractions regarding clinical trial design and submission requirements ahead of submitting documentation for approval in the se cond half of 2023. A pre - CTN discussion with the PMDA is planned for December 2022 with submission for CTN approval anticipated in the second half of 2023. With respect to Virtue SAB for Coronary ISR, Orchestra has been working on IDE approval with the FDA under the breakthr ou gh designation program to define all of the elements necessary for IDE approval and Orchestra expects to complete the agreed upon work and submit documentation for approval in Q1 of 2023. Orchestra and Terumo have had i nit ial interactions with the PMDA and expect to submit for CTN approval for Coronary ISR and SV studies in the second half of 20 23. FDA and PMDA responses are expected approximately 30 days following formal submissions; clinical study enrollment is expected to begin approximately 6 - 8 weeks after regulatory approvals; study enrollment timelines ar e currently estimated to be 12 - 18 months for all referenced studies although actual study enrollment timeframes may be longer; f inal primary endpoint results for all studies are at 12 months from enrollment with the exception of Japan Coronary ISR & SV studies, which are expected to be at 6 months from enrollment.
