When Gilead acquired CAR-T leader Kite Pharma, it made a crucial decision not to fully integrate it. This preserved Kite's distinct, individualized therapy operating model, which is fundamentally different from a traditional "off-the-shelf" drug company, proving a key lesson in M&A strategy for novel platforms.

Unlike traditional drug development, cell therapy logistics require extremely close, integrated relationships with contract research (CRO) and manufacturing (CDMO) organizations. Due to the direct line from patient to manufacturing and back, these partners function as critical extensions of the core team to ensure timeliness and safety.

Through a strategic collaboration with PreGene, Kite Pharma is leveraging China's distinct regulatory landscape. This partnership allows them to test and iterate on new in vivo cell therapy constructs more rapidly than is possible in Western markets, creating a significant competitive R&D advantage in a fast-moving field.

Observing that allogeneic ('off-the-shelf') cell therapies have not yet achieved their expected impact, Kite Pharma is strategically investing in in vivo approaches. Through acquisitions and partnerships, they are focusing on technologies that edit cells directly within the body, which have shown promising 'autologous-like' results.

When integrating acquired biotechs, Merck prioritizes retaining key talent and preserving ongoing science. The strategy involves immediate face-to-face engagement to reduce anxiety, followed by a pragmatic assessment of which processes must be standardized versus which can remain to avoid disrupting critical trials, a practice they call avoiding 'mercification'.

To avoid cultural dilution post-acquisition, the smaller company can maintain its identity by operating as a separate business entity within the larger organization. This allows them to preserve unique operational cadences and internal collaboration models, like Splunk's 'village' approach, amidst the broader integration process.

Scaling complex cell therapies follows a similar trajectory to monoclonal antibodies. The strategy involves establishing a global footprint with regional manufacturing facilities (e.g., US West, US East, Europe) to serve distinct geographic areas. This approach ensures manageable logistics and reliable delivery for personalized medicines, leveraging historical lessons.

For certain acquisitions like Poker, IFS deliberately avoids full integration to retain the target's agile, entrepreneurial culture. Instead, they use product connectors and provide access to parent company resources, allowing the startup to maintain its dynamism while leveraging scale.

The immense capital investment needed to build global manufacturing and commercial infrastructure makes it nearly impossible for most startup or mid-stage cell therapy companies to scale independently. According to Kite's Cindy Perettie, partnering with a large pharmaceutical company is a practical necessity for reaching global markets.
