AI-Programmable Biotherapeutics

The Frontier of Biotherapeutics

Smart Medicine for a New Era

Xenobiosys is pioneering Generation 3 Biotherapeutics. By coupling generative structural models with an integrated wet-lab feedback loop, we design programmable synthetic nanobodies and live biotherapeutic delivery systems with atomic precision.

Our Technology Platform

Moving past the limitations of traditional small molecules and standard biologics through closed-loop molecular engineering.

Closed-Loop AI & Wet Lab

Pure computational predictions fail without empirical ground truth. Our platform tightly integrates de novo generative models with internal bench testing, feeding real expression and binding data directly back into our fine-tuning loop.

Minimized Off-Target Liability

By embedding negative-selection filters and structural liability screening directly into our computational stage, we systematically triage out non-specific binding and conformational instabilities before synthesis.

Challenging Epitope Targeting

Hyper-specific single-domain scaffolds engineered to access recessed catalytic clefts and flat protein-protein interaction (PPI) interfaces that traditional immunoglobulins cannot engage.

Our Mission

At Xenobiosys, we believe the future of medicine lies in programmability. Our mission is to transform how therapeutic proteins are discovered, engineered, and delivered.

Generation 3 Biotherapeutics: The Shift to Deterministic Medicine

While Generation 1 (small molecules) and Generation 2 (biologics) transformed clinical care, both remain bound to empirical screening and what natural immune systems happen to evolve. Our Generation 3 paradigm treats molecular design as a deterministic discipline: computationally designing targeted proteins, validating them through continuous wet-lab feedback, and delivering them via autonomous biological systems.

Focus Areas

Oncology

Small-footprint single-domain proteins engineered for deep solid tumor penetration and specific engagement of tumor microenvironment targets.

Immunology

Targeted disruption of auto-immune and inflammatory signaling complexes with high structural selectivity.

Infectious Disease

Precision-designed affinity scaffolds capable of neutralizing evolving viral and bacterial surface antigens to overcome resistance.

Synthetic Nanobodies

Our engineered single-domain proteins represent a major step forward in therapeutic protein design. Derived from heavy-chain camelid antibodies, synthetic nanobodies combine antibody-level specificity with the stability and manufacturability of small proteins.

What We Do With Synthetic Nanobodies

Xenobiosys designs single-domain scaffolds with custom-tailored biophysical properties:

Property Traditional Antibodies Xenobiosys Synthetic Nanobodies
Size ~150 kDa ~15 kDa (10x smaller)
Tissue Penetration Limited Deep tissue penetration
Thermal Stability Moderate High (up to 80°C)
Production Cost High (mammalian cell culture) Low (microbial fermentation)
Design & Iteration Time 12-24 months 2-6 months (Closed-loop AI to bench)

Therapeutic Applications

High-Affinity Engagement

Our nanobodies bind pathological protein targets with nanomolar to picomolar affinity, blocking disease pathways while sparing normal cellular function.

Drug Conjugation

Compact and robust single-domain scaffolds serve as stable delivery vehicles for cytotoxic payloads, radioisotopes, or imaging agents directly to disease sites.

Multivalent Architecture

Modular engineering enables bi- and tri-specific constructs that simultaneously engage multiple epitopes or recruit immune effectors without heavy/light chain mispairing.

Live Biotherapeutic Products (LBPs)

Live Biotherapeutic Products represent our ultimate delivery horizon. Rather than relying solely on repeated systemic injections that degrade rapidly in circulation, Xenobiosys engineers biological chassis to express and deliver smart biotherapeutics directly at the site of pathology.

What We Do With LBPs

Our long-term LBP platform combines synthetic biology with microbiome science to establish autonomous therapeutic delivery:

In-Situ Expression

Engineered microbial chassis designed to survive physiological transit and colonize targeted tissue surfaces, providing continuous local production of our synthetic nanobodies without invasive IV administration.

Regulated Release

Microbial delivery systems programmed with genetic biosensors that trigger therapeutic release strictly in response to local pathology markers (such as inflammation signals, altered pH, or disease metabolites).

Overcoming Systemic Barriers

Local in-situ synthesis circumvents rapid renal clearance and systemic toxicity, maintaining protective concentrations directly at the target interface while improving long-term patient compliance.

The Generation 3 Convergence

Our closed-loop computational and laboratory engine designs and validates stable, high-affinity nanobodies. Our LBP platform provides the biological vehicle to deliver them autonomously at the point of disease—fulfilling the vision of living, programmable medicine.
