Dogfooding rfab-harness on 10 Challenging Cancer Targets

4,085 De Novo Antibody Designs Scored Across Pediatric & Adult Cancers

First systematic stress-test of rfab-harness across 10 cancer driver targets (B7-H3, GD2, EGFRvIII, HER2, CEACAM5, mesothelin, EphA2, GFAP, CD276, PDGFRA). Full RFdiffusion → ProteinMPNN → RF2 pipeline on Modal A100 GPUs. 135 of 4,085 designs passed stringent RF2 quality filters (pAE < 10, CDR RMSD < 2Å). Pass rates ranged 60-fold across targets—from 0.3% (EGFRvIII) to 19.8% (CEACAM5)—revealing strong target-dependent variation in designability.

Does Developability Come For Free?

FLAb Dataset Analysis

Testing whether de novo antibody design models learn therapeutic-like developability without explicit training. Analysis of 160 FLAb datasets reveals training data bias as the explanation for "emergent" developability.
