Bicycles are a new treatment modality combining the therapeutic benefits of antibodies, small molecules and peptides within one molecule. Bicycles exhibit the affinity and exquisite target specificity associated with antibodies, allowing intractable drug targets to be modulated often through interruption of protein-protein interactions. Bicycles’ small size enables rapid and deep tissue penetration, allowing tissues and tumours to be targeted from within. Bicycles’ peptidic nature provides, a “tuneable” pharmacokinetic half-life and a renal route of clearance, avoiding the liver and gastrointestinal tract toxicity often seen with other drug modalities.


Bicycles can be used as stand-alone therapeutic entities or coupled to deliver a variety of therapeutic payloads; Bicycle Therapeutics’ initial internal focus is to use Bicycles to selectively deliver toxins to tumours as Bicycle Drug Conjugates (BDCs). The company is also engaging in a range of collaborative models to help realize the full potential of the Bicycle technology for the development of therapeutics.
