SAN FRANCISCO—Covington advised Gilead Sciences, Inc. in its entry into a definitive agreement to acquire Tubulis GmbH, a private Germany-based, clinical-stage biotechnology company developing next-generation antibody-drug conjugates (ADCs), building on Gilead’s oncology pipeline. Under the terms of the sale and purchase agreement, Gilead will acquire all of the outstanding equity of Tubulis for $3.15 billion in upfront cash consideration on a cash-free, debt-free basis, subject to customary adjustments, which is payable at closing, and up to $1.85 billion in contingent milestone payments, for a total of up to $5 billion.
The acquisition significantly expands Gilead’s ADC capabilities by adding next-generation assets and platforms designed to more selectively deliver diverse payloads to tumors and maximize patient benefit. Tubulis’ lead asset, TUB-040, a NaPi2b-directed topoisomerase-I inhibitor (TOPO1i) ADC, is currently in Phase 1b/2 development for platinum-resistant ovarian cancer and non-small cell lung cancer (NSCLC). Gilead will also acquire TUB-030, a 5T4 targeted ADC, which has demonstrated promising initial clinical data across various solid tumor types. Tubulis’ programs and platforms have broad potential across multiple tumor types, complementing Gilead’s existing development and commercialization expertise in oncology.
Gilead is a biopharmaceutical company that has pursued and achieved breakthroughs in medicine for more than three decades, with the goal of creating a healthier world for all people. The company is committed to advancing innovative medicines to prevent and treat life-threatening diseases, including HIV, viral hepatitis, COVID-19, cancer and inflammation.
The Covington team was led by Ingrid Rechtin, Henning Bloss, and Amanda Austin.
