Upfront Briefing

Bigcap mRNA keeps consolidating: BioNTech closed its CureVac acquisition to deepen mRNA tech and manufacturing and keep the oncology thesis moving.

Meanwhile, private capital is still writing real checks—Syremis pulled in a $165M Series A for schizophrenia, Addition emerged from stealth, and Orum added $100M for an ADC-protein degrader platform (investors remain allergic only to small rounds).

On the product side, the FDA approved GSK’s twice-yearly asthma biologic Exdensur, a potential reset for severe-asthma maintenance cadence.

The Big 3

1
BioNTech acquires CureVac to boost mRNA technology, oncology
  • BioNTech has completed its acquisition of CureVac, aiming to strengthen its mRNA technology and manufacturing capabilities. This move reinforces BioNTech's leadership in the mRNA field and its oncology strategy.
  • Why it matters: With ~86.75% of shares tendered and a compulsory buyout expected in Jan 2026, BioNTech is effectively locking up CureVac’s IP + know-how to deepen mRNA design/delivery/manufacturing as it pushes harder into oncology.

Syremis Therapeutics raises $165M Series A for schizophrenia
  • Syremis Therapeutics, a biotech focused on schizophrenia drugs (lead = M1/M4 muscarinic agonist + NMDA antagonist), has secured a $165 million Series A financing round. This significant funding indicates strong investor confidence in its novel approach to treatments.
  • Why it matters: A “monster” A round signals that investors will still fund big, early schizophrenia bets—especially platforms positioned as the next wave after the recent mechanistic renaissance in the space.

Orum secures $100M for ADC-protein degrader platform
  • Orum has raised $100 million in funding for its innovative antibody-drug conjugate (ADC) and protein degrader technology. This investment highlights strong interest in its cancer treatment platform.
  • Why it matters: $100M behind degrader-antibody conjugates says private capital is leaning into complex modalities again—and Orum now has runway to advance its new lead (AML/CD123) after a strategic program reset.
