Multi-specific antibody programs in oncology — each on the same eight-to-sixteen-week path from sequence to in-vitro PoC; in-vivo schedule partner-lab dependent.
NOVA-3 · P1 — IMT030122
EpCAM × CD3 × 4-1BB trispecific TCE
EpCAM-positive epithelial tumors. Tumor-targeted T-cell engagement with 4-1BB costimulation to mitigate T-cell exhaustion associated with sustained CD3 engagement (mechanism requires validation). In-licensed program.
EpCAM — tumor targeting
CD3ε — TCR engagement
4-1BB — costimulation gate

NOVA-3 · P2 — IMB030202
EpCAM × 4-1BB × HSA
EpCAM-positive epithelial tumors. Tumor-localized 4-1BB costimulation (no CD3) designed to concentrate agonism in EpCAM-positive tissue while limiting systemic exposure; a human serum albumin (HSA) module extends half-life. Mechanism requires validation. In-licensed program.
EpCAM — tumor targeting
4-1BB — conditional costimulation
HSA — half-life extension

Workflow · the DBTL loop
Sequence to PoC in 8–16 weeks.
The same design–build–test–learn path runs under every program. Wet-lab results feed back into the Module Library, so each cycle starts from a stronger corpus. In-vivo schedule is partner-lab dependent.
Figure — DBTL cycle. Indicative durations from target intake to
in-vitro proof-of-concept; in-vivo efficacy work runs on the partner
lab’s schedule. Each completed cycle re-trains the Module Library.
Figure — The DBTL flywheel. Each program turns the same loop: DESIGN generates candidates, BUILD expresses and assembles them, TEST runs wet-lab SPR / BLI / ADCC assays, and LEARN folds the results back into the Module Library so the next cycle starts from a stronger corpus. The compounding rate shown (+~0.8% accuracy / program / cycle) is an internal target, not measured data.
Program detail · numbers
Where each program stands.
The pipeline today — all figures below are in-silico predictions and design targets; wet-lab validation is scheduled, not yet complete, and is labelled as such. P2 is the most advanced (in-vitro); P1 leads on clinical-relevance scope.
Figure — Program stages. Honest current stage of evidence for two active programs across five sequential development stages. Solid bars mark completed stages; dashed grey segments are planned, not-yet-started work, and the TODAY line marks the furthest any program has reached — no program shows in-vivo or clinical data.
P1
In silico PoC
P1 · Trispecific TCE with conditional costimulation
EpCAM tumor targeting × attenuated CD3 × 4-1BB conditional agonism. The third arm is a costimulation gate designed to concentrate agonism in the tumor microenvironment — designed to mitigate T-cell exhaustion from sustained CD3 engagement; conditional costimulation mechanism requires in-vitro and in-vivo functional validation. Lead candidate assembled from validated EpCAM, CD3, and 4-1BB modules.

P2 · Tumor-localized 4-1BB costimulator
EpCAM tumor targeting × 4-1BB conditional costimulation × HSA half-life extension. Tumor-localized 4-1BB agonism designed to concentrate costimulation in EpCAM-positive tissue while limiting systemic exposure; the HSA module extends serum half-life. No CD3 arm. Mechanism requires in-vitro and in-vivo functional validation. Cargo-agnostic scaffold.
