Gilead to buy Germany's Tubulis for up to $5 billion to boost cancer pipeline

Gilead's Strategic Acquisition of Tubulis

By Sriparna Roy

April 7 (Reuters) - Gilead said on Tuesday it would acquire Germany-based Tubulis GmbH for up to $5 billion, as it looks to strengthen its cancer drugs pipeline.

Background and Recent Acquisitions

This marks the latest in Gilead's acquisition spree. The company has been expanding beyond its key areas for growth amid looming patent expiries and declining sales ​of its COVID-19 treatment.

In February, the U.S. drugmaker bought partner ​Arcellx for up to $7.8 billion, while last month it agreed to acquire privately held ​biotech firm Ouro Medicines in a deal worth more than $2 billion.

Details of the Tubulis Deal

Access to Innovative Cancer Therapies

With the latest deal, Gilead will get access to Tubulis' experimental drugs, which belong to a class called antibody-drug conjugates (ADC), popularly known as "guided missiles", that deliver chemotherapy directly to cancer cells while minimizing harm to healthy tissue.  

Strategic Importance

We believe the Tubulis acquisition represents a strategically sound bolt-on that addresses Gilead's oncology pipeline growth needs, while securing differentiated next-gen ADC platform capabilities, said RBC Capital Markets analyst Brian Abrahams.

Tubulis' Drug Pipeline

Lead Asset: TUB-040

Tubulis' lead asset, TUB-040, which binds to NaPi2b, a protein found in certain cancer cells, is currently in early-stage development for a type of ovarian cancer and non-small cell lung cancer.

Additional Experimental Drugs

Another experimental drug, TUB-030, is being studied across various solid tumor types.

Early Trial Results and CEO Statement

"Our drugs in early trials have delivered very competitive data", said Tubulis CEO Dominik Schumacher.

"Now for me, it's all about how can we get this as quickly as possible to patients. And with a partner like Gilead, I think this is really the perfect way to get this vision into reality," he added.

Financial Terms and Future Operations

Gilead will acquire all of the outstanding equity of Tubulis for $3.15 billion in upfront cash, payable at closing, and up to $1.85 billion in milestone payments.

The companies have previously entered into licensing agreements to develop ADCs. Tubulis also has a partnership with Bristol-Myers Squibb 

After the deal closes, expected in the second quarter, Tubulis will operate as an ADC research organization within Gilead.

Key Takeaways

  • The acquisition gives Gilead access to Tubulis’ proprietary Tubutecan and Alco5 ADC platforms, promising more stable, durable targeted cancer therapies with reduced off‑target toxicity (pharmaphorum.com).
  • Tubulis’ lead clinical asset, TUB‑040 (targeting NaPi2b in ovarian and non‑small cell lung cancer), has received FDA Fast Track designation and is in Phase I/IIa trials; TUB‑030 targeting 5T4 is also advancing (lmu.de).
  • Tubulis recently raised €308 million (~$358 million) in Series C funding to accelerate ADC clinical development—underscoring strong investor confidence and setting high strategic value for Gilead’s acquisition (pharma.economictimes.indiatimes.com)
