Diverse Antibody Conjugate Formats
An Integrated Platform for Diverse Bioconjugates and Targeted Therapeutics.
Integrated review of PK, PK/PD, toxicology and bioanalytical datasets to support program decisions and portfolio progression.
Two distinct antigen-binding arms for dual tumour targeting — improved selectivity and internalisation efficiency.
Antibody–Oligonucleotide Conjugates
AOC · siRNA / ASO / miRNA
Cell-targeted delivery of RNA therapeutics. Oligonucleotide synthesis and conjugation chemistry — a new modality for o2h.
Two mechanistically distinct payloads on one antibody to overcome resistance. Site-specific cysteine chemistry (SH38/SW38 sites).
Targeted protein degradation via PROTAC or molecular glue. Addresses undruggable targets with o2h's existing degrader expertise.
Bioactive peptide payloads for receptor targeting, cell penetration or antimicrobial activity — leveraging o2h's in-house peptide platform.
Peptide-Scaffold Dual-Toxin Conjugates α-Helix scaffold · Lys / Cys orthogonal sites
A peptidic α-helix presenting lysine and cysteine at defined exposed positions, functionalised differentially to carry two distinct toxins at highly reproducible DAR. The resulting peptide is attached to an Ab or Fab.
