Management Comments

• Keith Gottesdiener, M.D., President and Chief Executive Officer of Prime Medicine, stated that the collaboration with Bristol Myers Squibb will apply their Prime Editing technology beyond rare genetic diseases, potentially unlocking opportunities in areas of high unmet needs.
• He also mentioned that efforts under this collaboration will leverage their PASSIGE technology, which they believe will advance their one-step, non-viral, multi-kilobase-size gene editing approach into the clinic.
• Teri Foy, Senior Vice President of Cancer Immunology and Cell Therapy Therapeutic Research Center at Bristol Myers Squibb, said that integrating Prime Medicine's technologies with their internal capabilities has the potential to open new avenues for innovation.

Industry Context

This announcement highlights the growing interest in gene editing technologies for therapeutic applications, particularly in cell therapy. The collaboration between Prime Medicine and BMS reflects a trend of large pharmaceutical companies partnering with innovative biotech firms to access cutting-edge technologies. The focus on ex vivo T-cell therapies aligns with the increasing importance of cell-based immunotherapies in oncology and immunology.

Comparison to Industry Standards

• The upfront payment of $110 million and potential milestones of over $3.5 billion are significant and comparable to other major biotech collaborations in the gene editing space.
• For example, CRISPR Therapeutics has similar deals with Vertex Pharmaceuticals and Bayer, with upfront payments and milestone payments in the hundreds of millions and billions respectively.
• The focus on ex vivo T-cell therapies is similar to the approach taken by companies like CARsgen Therapeutics and Allogene Therapeutics, which are developing allogeneic CAR T-cell therapies.
• Prime Medicine's PASSIGE technology, which enables large gene insertions, is a differentiator compared to traditional CRISPR-based gene editing, which is more focused on smaller edits.
• The company's focus on a modular platform and universal LNP delivery system is similar to the approach taken by companies like Moderna and BioNTech in the mRNA space, which allows for rapid development of new therapies.

Stakeholder Impact

• Shareholders will benefit from the increased funding and potential for future revenue.
• Employees will have opportunities to work on cutting-edge technologies and programs.
• Patients may benefit from the development of new therapies for genetic diseases.
• The collaboration with BMS may lead to increased visibility and credibility for the company.
• The strategic pipeline prioritization may lead to more efficient use of resources and faster development timelines.

Next Steps

• Prime Medicine will design Prime Editing reagents for BMS to develop ex vivo T-cell therapies.
• The company will file a registration statement for the resale of the shares issued to BMS.
• Prime Medicine will continue to advance its prioritized programs in hematology, immunology, oncology, liver, and lung diseases.
• The company expects to share initial clinical data from its Phase 1/2 trial in CGD in 2025.
• The company plans to advance its Wilson's disease program towards an IND application in the first half of 2026.
• Prime Medicine will continue to explore business development opportunities to expand its pipeline.
