Llamas are big pharma’s secret weapon to find new drugs

Pharma and biotech firms are developing llama-derived nanobody drugs targeting cancers, autoimmune, and inflammatory diseases with several candidates in clinical trials, aiming for future blockbusters.

  • In recent years, drug developers are advancing llama-derived nanobody candidates, with Sanofi's Cablivi as the first to reach the market; activity is centered near the university where findings originated.
  • Researchers note the platform can reach tight tissue and sometimes cross the blood-brain barrier, as nanobodies are smaller and simpler than human antibodies, making them easier to engineer, VIB scientists say.
  • But the field has seen setbacks, including MoonLake's market drop after a negative readout, despite Sanofi's �3.9 billion acquisition of Ablynx.
  • Shares moved sharply after clinical readouts, with investor markets reacting strongly to positive and negative results, exemplified by Eli Lilly & Co. partnering with Confo Therapeutics and AstraZeneca reporting results.
  • Researchers say the platform needs time to mature, with industry executives and researchers predicting nanobodies will become mainstream while maintaining llama herds and animal-care practices despite artificial intelligence advances.
