Item 1.01.

Entry into a Material Definitive Agreement.

Share Purchase Agreement

On May 11, 2022, Cullinan Oncology, Inc. (the “Company”), Taiho Pharmaceutical Co., Ltd. (“Taiho”) and Cullinan Pearl Corp. (“Pearl”), a subsidiary of the Company, entered into a Share Purchase Agreement (the “Purchase Agreement”) pursuant to which Taiho will acquire all of the Company’s equity interest in Pearl, and Pearl will become a wholly-owned subsidiary of Taiho (the “Acquisition”). In connection with the Acquisition, Taiho will make an upfront payment to the Company of $275 million and the Company may receive up to an additional $130 million upon the achievement of certain regulatory milestones related to Pearl’s lead program known as CLN-081 or TAS6417, an Epidermal Growth Factor Receptor inhibitor (the “Lead Program”).

The parties to the Purchase Agreement have each made customary representations, warranties and covenants. The parties have also agreed to cooperate with each other and use reasonable best efforts to make all filings and obtain all consents, approvals and authorizations of all governmental entities to the extent required by law in connection with the execution, delivery and performance of the Purchase Agreement and the consummation of the transactions contemplated thereby, subject to specified limitations. The Purchase Agreement also contains indemnification obligations of the Company, on the one hand, and Taiho, on the other hand, subject to certain limitations. Consummation of the Acquisition is subject to certain conditions, including the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and execution and delivery of the Co-Development Agreement (as defined below), as well as other customary closing conditions and deliverables. The Purchase Agreement may be terminated by either party under certain circumstances, including if the Acquisition is not consummated by June 30, 2022.

Co-Development Agreement

In connection with the consummation of the Acquisition, the Company will enter into a Co-Development Agreement (the “Co-Development Agreement”) with Taiho Oncology, Inc., an affiliate of Taiho (“Taiho Oncology”). Under the Co-Development Agreement, the Company and Taiho Oncology will co-develop the Lead Program and the Company will retain the option to co-promote the Lead Program in the U.S. together with Taiho Oncology. Taiho will commercialize the Lead Program in territories outside of the U.S. Taiho and the Company will share the future clinical development costs of the Lead Program for the U.S. and U.S. commercialization costs equally, and each will receive 50% of the profits from potential U.S. sales.

Either party can terminate the Co-Development Agreement in the event of material breach of the other party and the Company can terminate the Co-Development Agreement for convenience upon six months’ prior notice after completion of certain development activities, provided that the Company would continue to share development costs related to any clinical study that had been initiated prior to termination.

The foregoing descriptions of the Purchase Agreement and the Co-Development Agreement are only summaries of the material terms thereof, and do not purport to be complete. The descriptions are qualified in their entirety by reference to the Purchase Agreement and the Co-Development Agreement, which will be filed as exhibits to the Company’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2022.

 

Item 2.02.

Cullinan Oncology and Taiho Pharmaceutical Announce Strategic

Collaboration to Jointly Develop and Commercialize CLN-081/TAS6417 and

Taiho’s Acquisition of Cullinan Pearl

Taiho obtains exclusive global rights to CLN-081/TAS6417 outside the U.S.; in the U.S.,

Taiho and Cullinan Oncology to jointly develop and co-commercialize CLN-081/TAS6417

Cullinan Oncology will receive an upfront cash payment of $275 million, with potential

to receive up to an additional $130 million in regulatory-based milestone payments

Cullinan Oncology and Taiho will equally share future profits in the U.S.

CAMBRIDGE, Mass., May 12, 2022 (GLOBE NEWSWIRE) — Cullinan Oncology, Inc. (Cullinan Oncology) (Nasdaq: CGEM) and Taiho Pharmaceutical Co., Ltd. (Taiho) today announced an agreement through which Taiho will acquire Cullinan Pearl Corp. (Cullinan Pearl) and co-develop and co-commercialize Cullinan Oncology’s lead program, CLN-081/TAS6417 (development code in Cullinan Oncology: CLN-081, development code in Taiho: TAS6417), an orally available, differentiated, irreversible EGFR inhibitor that selectively targets cells expressing EGFR exon 20 insertion mutations while sparing cells expressing wild-type EGFR. Subject to customary closing conditions, including expiration or termination of the waiting period under U.S. antitrust laws, the acquisition is expected to close in the second quarter of 2022.

Under the agreement, Taiho will acquire Cullinan Oncology’s subsidiary, Cullinan Pearl, which has worldwide rights outside of Japan* to CLN-081/TAS6417, for an upfront payment to Cullinan Oncology of $275 million and up to an additional $130 million tied to EGFR exon20 non-small cell lung cancer (NSCLC) regulatory milestones.

Cullinan Oncology will co-develop CLN-081/TAS6417 and will retain the option to co-commercialize CLN-081/TAS6417 in the United States together with Taiho Pharmaceutical through its U.S. subsidiary, Taiho Oncology, Inc. Taiho will commercialize CLN-081/TAS6417 in territories outside U.S. and China. Taiho and Cullinan Oncology will equally contribute to the future clinical development of CLN-081/TAS6417 in the U.S., with each receiving 50% of the profits from potential U.S. sales. As a result of the upfront cash payment and reduction in development and pre-commercialization costs, Cullinan Oncology anticipates its cash runway to extend through 2026 based on current operating plans. This guidance does not include the potential regulatory milestone cash payments or future U.S. profit share post-launch.


It is estimated that approximately 85%1 of all newly diagnosed patients with lung cancer, or approximately 1.9 million people worldwide have NSCLC. Among those patients with NSCLC, approximately 2%2-3 or 38,000 patients have exon 20 insertions. In the U.S., approximately 16% of NSCLC cases harbor EGFR mutations, with insertions at exon 20 accounting for 12%(4) of those mutations. Patients with EGFR exon 20 insertions are known to have poorer outcomes than those with more common EGFR mutations, such as exon 19 deletion. CLN-081/TAS6417 is currently in Phase I/IIa development for treatment of patients with NSCLC having an exon 20 insertion mutation.

“We are pleased to bring CLN-081/TAS6417 back into our pipeline and move it towards commercialization with Cullinan Oncology,” said Masayuki Kobayashi, President and Representative Director of Taiho Pharmaceutical Co., Ltd. “Cullinan Oncology has carried CLN-081/TAS6417 from pre-IND to planned pivotal study in approximately three years. Meanwhile the Food and Drug Administration (FDA) has granted Breakthrough Designation status for this novel molecule. Utilizing Cullinan Oncology’s unique business model through this strategic collaboration, we aim to hasten and maximize the development of CLN-081/TAS6417. Together with Cullinan Oncology, the Taiho group will work to expeditiously deliver this agent to patients as soon as possible.”

“We are excited to embark on this collaboration with Taiho. Taiho is an ideal partner with whom to advance CLN-081/TAS6417 into later stage development and commercialization, given their deep understanding of the molecule and strategic focus on targeted therapies, existing stake in Cullinan Pearl, and strong oncology-focused commercial capabilities in the U.S.,” said Nadim Ahmed, Chief Executive Officer of Cullinan Oncology. “Importantly, the structure of the agreement provides the opportunity to efficiently establish our own commercial infrastructure, which will also be leveraged for our future programs. The transaction payments, reduced development expense, and potential ongoing revenue stream upon future commercialization will help us to devote greater resources to advance our robust pipeline of assets across a wide range of modalities, each with the potential to be the first or best in their class, to deliver on our promise to bring new therapeutic solutions to patients with cancer.”

Cullinan Oncology Conference Call Information

Cullinan Oncology will host a conference call today, May 12, at 8 a.m. EDT during which company executives will provide an overview of the collaboration. Investors and the general public are invited to listen to a live webcast of the call. A link to join the call and to find related materials will be available at: https://investors.cullinanoncology.com/news-events/events

About CLN-081/TAS6417

CLN-081/TAS6417 is an orally available tyrosine kinase inhibitor designed to target activating mutations in EGFR. The molecule was engineered to inhibit EGFR variants with exon 20 insertion mutations, while sparing wild-type EGFR. CLN-081/TAS6417 is a clinical candidate for NSCLC driven by EGFR exon 20 insertion mutations and is expected to be a novel therapeutic option for patients with highly unmet medical needs. In 2019, Taiho granted Cullinan Pearl, a company that Taiho and its subsidiaries and Cullinan Oncology had established together, an exclusive global license, excluding Japan, for the development and commercialization of CLN-081/TAS6417. Following this agreement, Cullinan Pearl rapidly advanced CLN-081/TAS6417, opening an Investigational New Drug application and initiating a global Phase I/IIa study in NSCLC patients harboring EGFR exon 20 mutations, which is currently ongoing. Cullinan Oncology announced that the FDA granted Breakthrough Therapy Designation for CLN-081/TAS6417 in early 2022. Cullinan Oncology and Taiho expect to initiate a pivotal study in the second half of 2022.
