Days after taking the unusual step, for a Chinese company, of terminating a couple of clinical programs, Bio-Thera Solutions Ltd. said it still plans to continue R&D in antibody-drug conjugates, but with a new technology platform, the company told BioWorld.
In an unusual move for a Chinese company, Bio-Thera Solutions Ltd. terminated the clinical development of its Trop2 antibody-drug conjugate (ADC), BAT-8003, and its PD-1 monoclonal antibody, BAT-1306, a month after it halted the phase III-stage HER2-ADC candidate BAT-8001.
Sutro Biopharma Inc.’s stock-perking news in early December with STRO-002, a folate receptor alpha-targeting antibody-drug conjugate (ADC) to treat ovarian cancer, reminded investors of potential in the class, which has been more than realized in recent years and could yield more upside in the near term. As of the Oct. 30 cutoff date, STRO-002 tallied one complete response and nine partial responses in the challenging indication, which works out to an overall response rate of 32% (10 out of 31) in evaluable patients.
DUBLIN – Boehringer Ingelheim GmbH is paying up to €1.18 billion (US$1.4 billion) to acquire antibody-drug conjugate (ADC) developer NBE-Therapeutics AG.

LONDON – Araris Biotech AG has raised CHF12.7 million (US$16.8 million) in a seed funding round to take forward what it claims is the holy grail for antibody-drug conjugates (ADCs), a linker technology that allows for the attachment of any payload to any antibody, without the need for engineering.
Antibody-drug conjugates (ADCs) are making a comeback. After a relatively slow start with Adcetris (brentuximab vedotin, Seattle Genetics Inc.) and Kadcyla (ado-trastuzumab emtansine, Roche Holding AG) approved by the FDA in 2011 and 2013, respectively, the regulatory activity has swelled with four FDA approvals over the last nine months.
In the company’s largest acquisition and potentially the fifth biggest biotech M&A ever, Gilead Sciences Inc. will acquire Immunomedics Inc. for $21 billion in a move that substantially transforms Gilead’s oncology portfolio.
Though falling short of the outright takeover that some may have hoped for, Merck & Co. Inc.’s dual tie-ups with Seattle Genetics Inc. (Seagen) put the latter in solid position to shop for acquisitions of its own.
