Wave of Mega-Deals Reshapes the Industry

October kicked off with a surge of high-stakes biotech deals as major pharmaceutical companies moved aggressively to bolster their pipelines. Massachusetts-based Aliada Therapeutics made headlines with its acquisition by AbbVie in a deal valued at $1.4 billion, positioning AbbVie to strengthen its neuroscience assets—most notably with Aliada’s antibody program targeting Alzheimer’s.

Major U.S. pharma Merck also flexed its M&A muscle, acquiring preclinical innovator Modifi Biosciences for up to $1.3 billion. Modifi’s DNA repair platform, aimed at hard-to-treat cancers, will now bolster Merck’s oncology ambitions. The company wasn’t done for the month, announcing a separate $1.9 billion partnership with Mestag Therapeutics to gain access to groundbreaking inflammatory disease targets.

Global M&A and Strategic Shifts

On the global stage, GSK’s $850 million buyout of Chimagen Biosciences in China brought a promising T cell engager for lupus into GSK’s clinical pipeline, building momentum in autoimmunity therapeutics. French pharma Sanofi invested heavily to strengthen its rare disease portfolio, securing global rights to Enjaymo from Recordati for a combined $825 million upfront and up to $250 million in milestones.

Meanwhile, in cancer therapeutics, Lyell Immunopharma snapped up California’s ImmPACT Bio for $67.5 million, aiming to gain a foothold in advanced CAR-T treatment for blood cancers. In another move, Galecto acquired a coveted preclinical leukemia medicine from Bridge Medicines, underscoring the drive towards first-in-class therapies.

Antibody-Drug Conjugates and Small Molecule Innovation

Antibody-drug conjugates (ADCs) were a standout trend, with South Korea’s LigaChem Biosciences inking a significant licensing and development deal with Ono Pharmaceutical worth up to $700 million. Meanwhile, Polish biotechs Ryvu and nCage are collaborating to create safer, next-generation ADCs with improved drug-to-antibody ratios.

Small molecule drug discovery remained a hotbed of investment. Ocean Biomedical struck a $32 million licensing agreement with Molecure to develop YKL-40 inhibitors for inflammation and fibrosis, while several public–private deals signaled confidence in innovative chemistry approaches.

Gene Therapy Partnerships: R&D Races Ahead

Multiple gene therapy partnerships also grabbed attention. Editas Medicine and Genevant Sciences launched an alliance to pair Editas’ CRISPR Cas12a gene editing systems with Genevant’s lipid nanoparticle tech—potentially accelerating next-gen gene editing medicines. The deal could be worth up to $238 million in upfront and milestone payments. Separately, the UK’s Nucleome Therapeutics and Johnson & Johnson are leveraging advanced genomics to identify the genetic roots of autoimmune diseases. Lilly and ViaNautis Bio are working together to deliver genetic payloads to targeted tissues, expanding the reach of genomic medicines.

Outlook: October Ushers in New R&D and Industry Alliances

Analysts note that October’s burst of billion-dollar deals reflects both consolidation in pharma and a red-hot race for innovation—especially in immunology, rare disease, and oncology. Despite broader economic caution, the willingness of major players to spend big on future R&D shows the sector’s confidence in science-driven growth.
