Media Release

• Collaboration to discover and evaluate novel product concepts based on the combination of Genmab’s antibodies and bispecific antibody technologies with Bolt’s proprietary immune-stimulating antibody conjugate (ISAC) platform
• Companies intend to develop multiple bispecific ISACs
• Genmab has option to develop and commercialize up to three therapeutic candidates; Bolt has option to participate in development and commercialization of one candidate
• Bolt to receive USD 10 million upfront payment and USD 15 million equity investment from Genmab

Genmab A/S (Nasdaq: GMAB) and Bolt Biotherapeutics, Inc. (Nasdaq: BOLT) announced today that the companies have entered into an oncology research and development collaboration. Together, the companies will evaluate Genmab antibodies and bispecific antibody engineering technologies in combination with Bolt’s proprietary Boltbody™ immune-stimulating antibody conjugate (ISAC) technology platform, with the goal of discovering and developing next-generation, immune-stimulatory, antibody-based conjugate therapeutics for the treatment of cancer. This research collaboration will evaluate multiple bispecific ISAC concepts to identify up to three clinical candidates for development. Genmab will fund the research, along with the preclinical and clinical development of these candidates through clinical proof of concept.

“This exciting collaboration will provide a unique opportunity to combine Genmab’s innovative bispecific antibody technologies with Bolt’s powerful, advanced ISAC technology to develop targeted antibody products with the potential to transform cancer treatment,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab. “Genmab’s partnership approach is part of our DNA and we are pleased to be collaborating with Bolt to develop and deliver potential next-generation cancer therapeutics to patients in need of novel treatment options.”

Randall Schatzman, Ph.D., Chief Executive Officer of Bolt, explained, “Our joint vision is to leverage Genmab’s and Bolt’s innovative technologies to develop a completely new type of ISAC with the aim to transform the way cancer is treated. Creating bispecific ISACs turbo-charged with potent immune stimulants is a novel concept that has tremendous potential for patients. We are delighted to be collaborating with the Genmab team and to have their deep expertise in discovering and developing bispecific antibodies brought to bear on this approach as we continue our mission to develop treatments that address key unmet needs for patients with cancer.”

Financial Terms

Under the terms of the agreement, Genmab will pay Bolt an upfront payment of USD 10 million. Genmab will also make a USD 15 million equity investment in Bolt. Bolt is eligible to receive total potential milestone payments of up to USD 285 million per therapeutic candidate exclusively developed and commercialized by Genmab, along with tiered royalties. Genmab will fully fund pre-clinical and early clinical development of all candidates. If a candidate is co-developed, development costs will be split 50:50 between the two companies, and the companies will be solely responsible for commercialization costs in their respective territories and shall pay each other royalties on product sales.

About Bolt Biotherapeutics, Inc.

Bolt Biotherapeutics, Inc. is a clinical-stage biotechnology company pioneering a new class of immuno-oncology agents that combine the targeting precision of antibodies with the power of both the innate and adaptive immune systems. Bolt’s proprietary Boltbody™ Immune-stimulating Antibody Conjugates (ISACs) are designed to target tumor cells for elimination by myeloid cells, which then activates the myeloid cells to recruit the adaptive immune system in the anti-tumor response. This leads to the conversion of immunologically “cold” tumors to “hot” tumors. Bolt’s lead candidate, BDC-1001, is a Boltbody ISAC comprised of a HER2-targeting biosimilar of trastuzumab conjugated with a non-cleavable linker to one of Bolt’s proprietary TLR7/8 agonists for the treatment of patients with HER2-expressing solid tumors. Bolt is also advancing BDC-2034, a Boltbody ISAC targeting CEA, and a pipeline of other immuno-oncology products.
