Lacking internal research capabilities, Mirum's core business model is to in-license or acquire promising assets. This strategy, initiated in 2018 with assets from Shire, relies on their proven operational team to develop and maximize the value of external innovations.

Western pharma firms strategically license assets from Chinese biotechs while leaving China rights with the local partner. This leverages China's faster, cheaper clinical development, as the partner tests the molecule in new indications, generating valuable data that de-risks the asset for the global firm at no extra cost.

The "NewCo" model, where a new company is formed around assets licensed from an existing firm, is a key strategy for Western investors to access a deep well of innovation from Chinese companies like Heisco, which are largely unknown in the West but possess broad, innovative pipelines.

Rather than inventing from scratch, InMedx licensed its advanced heart-rate variability algorithm from Omega Wave, a company serving pro sports teams. This allowed them to leverage a proven, precise technology and focus their resources on the higher-value activities of clinical validation and securing FDA clearance for medical use.

Mirum views the retreat of large pharmaceutical companies from the rare disease space as a strategic opportunity. This creates a less competitive environment for acquisitions, allowing Mirum to acquire assets that are often overlooked by larger players and serve patient populations others leave behind.

After years of focusing on de-risked late-stage products, the M&A market is showing a renewed appetite for risk. Recent large deals for early-stage and platform companies signal a return to an era where buyers gamble on foundational science.

While known for late-stage acquisitions, Mirum strategically uses smaller deals for early-stage assets to expand its capabilities. The Anthoran Therapeutics deal serves as a model: a low upfront payment with a back-ended structure allows Mirum to enter early-phase development—a new area for the company—while managing financial risk.

Mirum's acquisition strategy targets late-stage assets like berlovitug that can leverage its established global commercial operations. This approach maximizes efficiency, as new products fit into the existing sales structure supporting its current portfolio, especially in the adult hepatology space, making the acquisition highly strategic.

Instead of solely relying on replicating internal R&D success, a proven biotech can create value by acquiring passive assets. This involves buying royalty streams on promising external products, leveraging the company's evaluation and deal-making expertise in a new way.

With patent cliffs looming and mature assets acquired, large pharmaceutical companies are increasingly paying billion-dollar prices for early-stage and even preclinical companies. This marks a significant strategic shift in M&A towards accepting higher risk for earlier innovation.

Ipsen avoids the high-risk, capital-intensive phase of basic research. Instead, its R&D strategy focuses on licensing promising drug candidates from universities and biotechs. The company then leverages its expertise in later-stage development, including toxicology, manufacturing scale-up (CMC), and clinical trials, to bring these de-risked assets to market.
