Cullinan Oncology Licenses U.S. Rights to the First
CAMBRIDGE, Mass., Feb. 13, 2023 (GLOBE NEWSWIRE) -- Cullinan Oncology, Inc. (Nasdaq: CGEM) and Harbour BioMed (HKEX: 02142) today announced that Cullinan Oncology has entered into an exclusive license with Harbour BioMed for the development and commercial rights of HBM7008 (CLN-418) in the U.S. CLN-418/HBM7008 is a B7H4 x 4-1BB bispecific immune activator developed from next-gen heavy chain only antibody (HCAb)-based multi-specific antibody discovery platform HBICE®, currently in a Phase 1 clinical study being conducted at U.S. and Australian sites in patients with advanced solid tumors.
“We are pleased to bring CLN-418, a potential first-in-class, clinical-stage bispecific immune activator, into our diversified portfolio. We believe the best approach to conditional activation of 4-1BB is by targeting B7H4, a tumor associated antigen that is highly expressed across multiple cancers and minimally overlaps with PD-L1 expression. CLN-418 is a strong strategic fit for Cullinan, building on our expertise with bispecifics, and placing us at the forefront of bispecific antibody development in solid tumors. Importantly, this transaction adds another clinical-stage asset to our portfolio, and with it, we are on track to have potentially six clinical stage assets in our pipeline by the end of 2023,” said Nadim Ahmed, Chief Executive Officer of Cullinan Oncology. “This transaction is consistent with our goal to strategically deploy capital to expand and advance our pipeline, and the financial terms of the agreement allow us to maintain a multi-year cash runway to fund our ongoing development efforts and deliver data from multiple clinical programs. Harbour BioMed is a global clinical-stage biotech company with experienced therapeutic innovation capabilities and a network of partnerships, and we look forward to realizing the full potential of this exciting program.”
Under the agreement, Cullinan Oncology will pay Harbour BioMed an upfront license fee of $25 million at closing for the exclusive right to develop and commercialize CLN-418/HBM7008 in the U.S. Harbour BioMed will be eligible to receive up to $148M in development and regulatory milestones plus up to an additional $415M in sales-based milestones as well as tiered royalties up to high teens on potential U.S. commercial sales.
“This agreement is another validation from a leading global biotech company on our technology platforms and innovation capabilities. We believe that Cullinan Oncology is the ideal partner to continue the development of CLN-418/HBM7008, which we believe has first-in-class potential to treat a wide range of solid-tumor cancers. They have a seasoned clinical development team, strong capabilities in oncology drug development, and the robust infrastructure necessary to move it forward,” said Dr. Jingsong Wang, Founder, Chairman and CEO of Harbour BioMed. “We look forward to working with Nadim and his team to advance this program forward.”

CLN-418/HBM7008 is the only B7H4 x 4-1BB bispecific immune activator in clinical studies. Both B7H4 and 4-1BB have been targets of high interest and both have been evaluated clinically. Their distinct biology and mechanisms of action provide strong rationale to combine them as a bispecific antibody.
B7H4 is an attractive tumor associated antigen (TAA) highly expressed on multiple tumor types, including triple negative breast cancer, ovarian cancer, and lung cancer, while expression on normal tissue is low. A coinhibitory immune checkpoint with PD-L1 in the B7 family, B7H4 has minimal overlap with PD-L1 expression. Targeting B7H4 has the potential to address tumor types for which PD-L1-based immunotherapies have exhibited limited efficacy.
4-1BB is a key costimulatory molecule for both T- and NK-cell engagement and is being studied in multiple clinical programs. However, safety concerns such as hepatic toxicity remain despite the biological validation of the 4-1BB pathway. Conditional activation of 4-1BB in the tumor microenvironment that is dependent on B7H4 expression presents a novel approach to harness the potential of both targets. CLN-418/HBM7008, with strict TAA crosslinking dependent T-cell activation, can potentially translate to better safety and a more favorable therapeutic window.
The ongoing Phase 1 trial (NCT05306444) is an open-label, multicenter study being conducted at U.S. and Australian sites evaluating the safety, tolerability, pharmacokinetics and anti-tumor activity of CLN-418/HBM7008 administered intravenously in patients with advanced solid tumors. The study, which is expected to enroll up to 108 subjects, aims to identify a maximum tolerated dose and a recommended Phase 2 dose of CLN-418/HBM7008. Initial clinical data from this study could be available in 2024.
