• Proposed reverse merger with OrthoCellix, a wholly-owned subsidiary of Ocugen, to create Nasdaq-listed, late clinical-stage regenerative cell therapy company with a first-in-class technology platform, focused on orthopedic diseases
  • OrthoCellix is developing the Phase 3-ready NeoCart® as an autologous cartilage implant technology utilizing patient cells to repair articular cartilage defects of the knee

PHILADELPHIA, PA and MALVERN, PA, USA I June 23, 2025 I Carisma Therapeutics Inc. (Nasdaq: CARM) (Carisma) and OrthoCellix, Inc. (OrthoCellix), a wholly-owned subsidiary of Ocugen, Inc. (Nasdaq: OCGN) (Ocugen), a clinical-stage company developing regenerative cell therapies for orthopedic diseases, today jointly announced that they have entered into a definitive merger agreement to combine the companies in an all-stock transaction. The combined company will focus on the development of OrthoCellix’s NeoCart® technology for the treatment of knee articular cartilage defects and plans to initiate a U.S. Food and Drug Administration (FDA)-endorsed Phase 3 clinical trial for NeoCart®.

“We believe merging OrthoCellix with Carisma will allow us to create a publicly-traded company focused on the development of NeoCart® and provide value for both Ocugen and Carisma stockholders while unlocking true market potential of NeoCart®,” said Dr. Shankar Musunuri, Chairman, Chief Executive Officer, and Co-founder of Ocugen. “We believe NeoCart® has tremendous potential to deliver a truly transformative approach to cartilage repair, and we’ve established OrthoCellix with dedicated resources to bring this revolutionary technology to the patients who desperately need it.”

“Carisma evaluated a range of strategic alternatives, and we believe this proposed transaction represents an opportunity to deliver significant value to our stockholders,” said Steven Kelly, President and Chief Executive Officer, of Carisma. “OrthoCellix is strongly positioned with its NeoCart® platform, a dedication to developing regenerative cell therapies, and a well-credentialed management team to lead the combined company.”

About OrthoCellix’s NeoCart® Portfolio

OrthoCellix is developing NeoCart® as an autologous cartilage implant technology utilizing patient cells to repair articular cartilage defects of the knee. The novel platform merges a fortified 3D scaffold and patented bioprocessing technology to grow chondrocytes—the cells responsible for maintaining cartilage health—to produce adolescent-like cartilage at the time of implant. NeoCart® has the potential to accelerate healing and reduce pain by creating a similar, functional joint surface to help patients return to normal activities and prevent complications associated with articular cartilage damage.

OrthoCellix anticipates launching its Phase 3 clinical trial by the end of 2025. Previously, NeoCart® received Regenerative Medicine Advanced Therapy (RMAT) designation and concurrence from the FDA on a single, confirmatory Phase 3 clinical trial to enable submission of a Biologics License Application.

About the Proposed Transactions

Under the terms of the merger agreement, OrthoCellix will merge with and into a wholly-owned subsidiary of Carisma, with OrthoCellix continuing as a wholly-owned subsidiary of Carisma and the surviving company of the Merger. Carisma will issue to the pre-merger OrthoCellix stockholder shares of Carisma common stock as merger consideration in exchange for the cancellation of shares of capital stock of OrthoCellix. Carisma also expects to enter into subscription agreements for a private financing with Ocugen and other select investors, which is expected to close concurrently with the completion of the merger, to enable the combined company to complete the Phase 3 trial of NeoCart® without any additional cost or investment from Ocugen. In connection with the closing of the proposed transactions, Carisma stockholders will be issued contingent value rights representing the right to receive certain payments from proceeds received by the combined company, if any, related to Carisma’s pre-transaction legacy assets.

Under the terms of the merger agreement, upon the closing of the proposed transactions and after giving effect to the contemplated $25.0 million concurrent financing, OrthoCellix’s stockholder and the other participants in the concurrent financing are expected to own approximately 90% of the combined company, and existing Carisma stockholders are expected to own approximately 10% of the combined company, each on a fully diluted basis. The percentage of the combined company that each company’s former stockholders will own after completion of the merger is subject to adjustment based on Carisma’s net cash at the closing and the proceeds from the concurrent financing, among other adjustments, in each case as described in the merger agreement.

Upon the closing of the proposed transactions, “Carisma Therapeutics Inc.” is expected to be renamed “OrthoCellix, Inc.” and trade on the Nasdaq Capital Market under the ticker symbol ‘OCLX.’

The transaction has been unanimously approved by the board of directors of both companies and is expected to close in the second half of 2025, subject to customary closing conditions, including approvals by the stockholders of each company and the effectiveness of a registration statement to be filed with the Securities and Exchange Commission (the “SEC”) to register the shares of Carisma common stock to be issued in connection with the merger. In connection with the companies’ entry into the merger agreement, directors and officers of Carisma and OrthoCellix’s stockholder have executed support agreements, pursuant to which they have agreed to vote all of their shares of capital stock in favor of the merger or the issuance of Carisma equity in the merger, as applicable.
