Merus and Biohaven partner to co-develop bispecific ADC therapies

Merus N.V. and Biohaven Ltd. have announced a strategic collaboration to advance the development of three bispecific antibody-drug conjugates (ADCs), combining their respective expertise in antibody engineering and conjugation technology. The partnership aims to produce next-generation therapies that promise enhanced precision and efficacy for cancer treatment.

Pioneering Bispecific Antibody-Drug Conjugates

The partnership leverages Merus’ proprietary Biclonics platform, which has been instrumental in producing FDA-approved therapies such as Bizengri and clinical candidates like petosemtamab. Biohaven brings its next-generation ADC technologies, including linker, payload, and conjugation advancements, to the table. Together, the companies aim to develop therapies that improve on existing ADC approaches, offering greater potency and selectivity for various cancer types.

The collaboration includes three ADC programs: two derived from Merus’ Biclonics platform and one under preclinical development. Biohaven will manage the ADC generation for these programs, while Merus will focus on preclinical antibody engineering. Upon meeting mutually agreed-upon milestones, the companies will share the costs of external development and commercialization.

Peter B. Silverman, Chief Operating Officer of Merus, expressed confidence in the partnership’s potential, stating that the collaboration combines Merus’ proven antibody technology with Biohaven’s innovative conjugation techniques. He highlighted the unique opportunity to create differentiated therapies that address unmet needs in oncology.

Accelerating the Development of Targeted Cancer Therapies

Biohaven’s President of Oncology, Brian Lestini, emphasized that the partnership could significantly advance the field of bispecific ADCs. He explained that by leveraging Biohaven’s expertise in payload delivery and conjugation, the collaboration aims to produce therapies with improved efficacy and safety profiles. These innovations could provide meaningful benefits to cancer patients, particularly in areas where existing therapies fall short.

ADCs are among the most promising advances in oncology, combining the targeting precision of monoclonal antibodies with the cytotoxic strength of chemotherapy. Bispecific ADCs take this approach a step further by targeting two antigens simultaneously, potentially increasing treatment specificity and reducing off-target effects.

Agreement Details and Industry Impact

Under the terms of the agreement, Merus will receive an upfront payment and license fee upon the nomination of the first ADC candidate. Each program’s preclinical development costs will be divided between the companies, with Merus managing bispecific antibody generation and Biohaven handling ADC development. Once the programs advance to clinical stages, the companies plan to share development and commercialization costs equally.

This collaboration reflects broader trends in the biopharmaceutical industry, where partnerships are driving the development of complex therapies. ADCs represent a rapidly growing segment, with the global market projected to surpass $10 billion by 2028. By combining their expertise, Merus and Biohaven are positioning themselves as leaders in this competitive landscape.

The partnership also underscores the increasing importance of bispecific antibodies in oncology. These therapies can address multiple pathways simultaneously, providing a more comprehensive approach to targeting cancer cells. By integrating bispecific technology with advanced ADC platforms, the collaboration has the potential to produce groundbreaking treatments that redefine standards of care.

Looking Ahead

If successful, the Merus-Biohaven collaboration could set a precedent for future partnerships in the ADC space. By demonstrating the value of combining innovative technologies, the companies aim to accelerate the development of therapies that improve outcomes for patients with hard-to-treat cancers.

In addition to its potential impact on patient care, the collaboration highlights the role of innovation in driving industry growth. By investing in advanced platforms like Biclonics and cutting-edge ADC technologies, biopharmaceutical companies can expand their pipelines while addressing critical unmet needs in oncology.

The Promise of Advanced ADC Technologies

As the demand for more effective and targeted cancer therapies grows, collaborations like this one are becoming increasingly important. By pooling their expertise, Merus and Biohaven are not only advancing their own pipelines but also contributing to the broader field of oncology research.

This partnership could pave the way for new standards in ADC development, emphasizing the importance of precision, safety, and efficacy. The success of these programs could lead to the adoption of similar strategies by other companies, further accelerating innovation in cancer treatment.
