Elise Biopharma’s Monoclonal Antibodies & Biologics CDMO platform is engineered
What are monoclonal antibodies and biologics—why they demand a different CDMO
Monoclonal antibodies are engineered immunoglobulins that bind a single epitope with high affinity; modern formats span IgG1–IgG4, Fc-silenced variants, afucosylated ADCC enhancers, and multispecific architectures that solve targeting, avidity, or receptor crosslinking problems. “Biologics” is the broader class—recombinant proteins, Fc-fusions, cytokines, enzymes, and complex modalities that require living systems to express, fold, glycosylate, and assemble correctly.
Unlike small molecules, their critical quality attributes (CQAs)—glycoform distribution, charge variants, aggregate profile, potency—emerge from cells + process. That’s why a great Monoclonal Antibodies & Biologics CDMO doesn’t just “run equipment”; it engineers cells, controls mass-transfer and metabolism, orchestrates multicolumn chromatography, and proves—quantitatively—why the result will be stable, potent, and safe at clinical and commercial scale.
Our operating thesis
At Elise Biopharma, we convert discovery assets into regulator-ready drug substance with ruthless predictability. We fuse cell-line development, upstream process design, continuous/connected DSP, glycoform tuning, high-concentration formulation, and aseptic fill/finish into one governed control narrative. The method is simple and non-negotiable: physics first, then machine learning, then paperwork that proves it. This is why sponsors describe us as the best Monoclonal Antibody CDMO in the United States—and why our programs transfer cleanly, scale reliably, and pass audits without drama. It’s also why our Monoclonal Antibodies & Biologics CDMO stack outperforms: every lever that moves titer, purity, potency, and stability is modeled, instrumented, and validated before it becomes your risk.
Executive summary:
- End-to-end Monoclonal Antibodies & Biologics CDMO execution grounded in QbD, risk-based characterization, and ALCOA+ data integrity—designed for rapid PPQ and bulletproof CPV.
- CHO/HEK cell-line creation with expression governance: copy-number control, integration-site mapping, clonal stability under perturbation, and developability screens (SEC-MALS, icIEF, LC-MS peptide maps).
- Upstream PAT (capacitance, Raman/FTIR, off-gas MS) fused into soft sensors; model-predictive control (MPC) that keeps CPPs in the narrow bands where CQAs behave and glycoforms stay on-target.
- Downstream options spanning Protein A and alkali-tolerant alternatives, continuous PCC/SMB capture, viral-clearance hardening, glycoform-aware polishing (CEX/AEX/HIC/mixed-mode), and low-shear UF/DF sized by viscosity physics.
- Formulation science for high-concentration antibodies (150–200+ mg/mL): viscosity mitigation (buffer/arginine/salt systems), interfacial-stress control, and lyophilization cycle digitalization (Tc/Tg′ guided, controlled nucleation).
- In-house release analytics: LC-MS/MS identity, CE-SDS (r/nr), SEC-MALS aggregates, icIEF/CEX charge variants, HCP and host-cell DNA ELISAs/qPCR, Fc-effector potency (ADCC/CDC/ADCP), and orthogonal comparability packages.
- A brand-new 120,000-square-foot Massachusetts facility dedicated to antibody/biologic manufacturing—segregated flows, large-format Protein A, multi-column skids, perfusion-ready USP, and ISO-5 robotic-isolator fill/finish.
- Throughout this page, when we write Monoclonal Antibodies & Biologics CDMO, we mean the total system: engineered cells, controlled bioreactors, adaptive chromatography, formulation physics, and documentation that will stand up to inspection—anywhere.
Cell line development (CLD)
Hosts & vectors. We work across CHO-S, CHO-K1, CHOZN®, and HEK293 systems with promoter/scaffold choices that balance productivity and product quality. Integrations are either site-specific (landing pads, transposase systems) or curated random integrations screened by qPCR copy-number, junction mapping, and in situ expression stability. Transient HEK is used for rapid feasibility; stable lines are advanced for IND-enabling work.
Screening to selection. AMBR®/high-throughput mini-bioreactors run factorials over feed composition, osmolality, pH, and temperature while we track glycoform distributions, charge variants, and specific productivity (qP). We rank clones by quality under perturbation, not just headline titer. Stability studies (≥60 doublings) ensure expression doesn’t drift when the calendar does.
Developability. Early SEC-MALS, icIEF, DSF/DSC, and LC-MS peptide mapping flag aggregation, charge heterogeneity, and PTM liabilities. Sequence-level liabilities (Asn deamidation, Asp isomerization, unpaired cysteine) trigger targeted re-engineering before money hits the big reactors.
Why it matters. In a true Monoclonal Antibodies & Biologics CDMO model, CLD is not a separate island. The same PAT we use in manufacturing trains the soft sensors during clone screens, so the process you license later behaves like the process you optimized today.
Upstream process design: control loops that make CQAs behave
Design space definition. We identify CPPs—pH, DO, temperature, specific feed rate, osmolality, and back-pressure—then execute Bayesian DoE to map their interactions against titer, glycoforms, aggregates, and charge variants.
PAT fusion → soft sensors.
- Raman/FTIR models for glucose, lactate, glutamine, ammonia.
- Capacitance for viable cell volume and qP inference.
- Off-gas MS for OUR/CTR and respiratory quotient.
Features feed a digital twin (mechanistic mass/energy balances + ML shell). The twin forecasts trips and recommends setpoints; MPC enforces multivariable constraints so you never trade oxygen transfer for heat catastrophe.
Temperature and pH choreography. We stage shift regimes that maximize qP without sacrificing glycoform quality (e.g., afucosylation targets) and align with downstream viral clearance robustness. Anti-foaming is mechanical or back-pressure-driven by default; if chemical defoamer is essential, resin compatibility and post-use CIP are validated pre-campaign.
Perfusion and intensified fed-batch. For unstable products or aggressive timelines we deploy ATF/TFF perfusion with retention stability models and viral safety overlays. Intensified fed-batch uses seed-densification and smart feeds to compress cycle times without glycoform drift.
This is Monoclonal Antibodies & Biologics CDMO in practice: a cyber-physical loop that turns variability into guard-railed performance.
Downstream purification: continuous when it pays, orthogonal when it counts
Protein A and alternatives. We maintain large-column Protein A capacity and also master Protein A alternatives (alkali-tolerant ligands, mixed-mode captures) where cost or leachables warrant. Column sizing is done from dynamic binding capacity under your broth—not brochure numbers. Load, wash, and elute windows are optimized via in-line UV/cond and pool analytics to minimize host protein bleed and leachable risk.
Continuous capture—PCC/SMB. Multi-column capture raises resin utilization and flattens batch variability; inline-dilution and surge tanks are modeled so viral inactivation steps remain compliant.
Polishing trains. We execute orthogonal removal of aggregates, fragments, charge variants, residual DNA/HCP, and viral safety requirements with CEX/AEX, HIC, MM resins, and membrane polishers. HIC design spaces are mapped to reduce high-salt liabilities; CEX windows are tuned to chase acidic or basic variants depending on function.
UF/DF physics. We select membranes for minimal adsorption, define TMP×time envelopes to protect structure, and run viscosity-aware concentration for high-concentration biologics without shear surprises.
Viral safety. Robust low-pH inactivation modeling, nanofilters with real-time pressure monitoring, and spike/recovery packages documented to the last decimal.
Every train is documented in a way that convinces regulators your Monoclonal Antibodies & Biologics CDMO path is orthogonal, scalable, and defendable.
Glycoengineering & effector-function tuning
Afucosylation / ADCC. We hit afucosylation targets with FUT8-attenuated hosts, Mn²⁺/uridine supplementation, and temperature/pH shapes that maintain productivity. Potency is verified by FcγRIIIa binding and NK cell-based ADCC.
Sialylation / half-life. We manage terminal sialic acids via ST3GAL/B4GALT pathway modulation and media chemistries, tracking effects with HILIC-FLD and LC-MS glycopeptide maps.
Charge variants. We map icIEF profiles to function and then use CEX windows to restrict outliers while preserving the right glycoform spectrum.
Where sponsors need an edge, our Monoclonal Antibodies & Biologics CDMO program couples glycan physics to clinical intent, not aesthetics.
High-concentration formulation & lyophilization science
Viscosity management. We model colloidal interactions and screen histidine/acetate buffers, sugars (trehalose/sucrose), polymers, NaCl/Arginine blends, and surfactants to reduce viscosity at ≥150 mg/mL without destabilizing the interface.
Interfacial stress control. Agitation and freeze-thaw panels map particle generation; interfacial excipients and process hardware (low-shear pumps, pre-wet filters) are locked to prevent subvisible particles.
Lyo cycle digitalization. We estimate critical temperatures (Tc/Tg′) and build cycles via MTM/manometric data; controlled nucleation and smart primary-drying ramps maintain cake structure and reconstitution kinetics.
High-concentration success is where many biologics stumble; it’s where a Monoclonal Antibodies & Biologics CDMO leader shows up.
Analytics & QC: speed with teeth
- Identity/integrity: intact mass, LC-MS/MS peptide maps, N-/O-glycan analysis.
- Purity/aggregates: SEC-MALS, CE-SDS (r/nr), SDS-PAGE.
- Charge/glycoform: icIEF, CEX-HPLC, HILIC-FLD.
- Potency: Fc effector assays (ADCC/CDC/ADCP), binding kinetics (SPR/BLI), cell-based readouts.
- Residuals: HCP ELISA (platform/custom), HC-DNA qPCR, Protein A leachables.
- Viral safety: inactivation validation, nanofiltration integrity.
- Stability: ICH Q1A real-time/accelerated; forced degradation (thermal, oxidative, agitation, light) with structure–function linkage.
All data sits in an ALCOA+ historian with version-controlled methods. Reports read like they were written by your QA—because they are.
Digital twins & AI-orchestrated control for antibodies
Our upstream/downstream twins combine transport physics and reaction kinetics with ML models trained on spectral and historian features. They forecast oxygen/heat limits, glycan drift risk, chromatography breakthrough, and UF/DF fouling. MPC closes the loop, and drift detectors watch model residuals during CPV. This is not a dashboard; it is the engine that keeps your Monoclonal Antibodies & Biologics CDMO process on rails.
Tech transfer, PPQ, and CPV
Tech transfer. We ship SOPs, historian tag maps, PAT models, setpoints, and alarm logic. The receiving site runs shadow control until metrics prove equivalence.
PPQ strategy. Risk-based PPQ defines critical conditions and challenge tests relevant to your CQAs. We demonstrate reproducibility across equipment, materials, and operators.
Continuous process verification. Beyond SPC on CQAs, CPV tracks soft-sensor residuals and MPC performance. Seasonal utility shifts or raw-material lot effects get caught before they turn into deviations.
That end-to-end traceability is what makes an elite Monoclonal Antibodies & Biologics CDMO different from a plant with good intentions.
Representative case snapshots
1) Afucosylated mAb with potency scatter at scale.
Root cause: uncontrolled temperature/pH drift during late-phase feeds. Fix: twin-tuned MPC + FUT8 pathway nudges + CEX polish targeting basic variants. Outcome: <5% CV on afucosylation; potency variance halved.
2) High-concentration ophthalmic mAb with viscosity >60 cP.
Approach: arginine-histidine system, controlled NaCl micro-additions, shear-conscious UF/DF, and surfactant equilibration strategy. Outcome: 200 mg/mL at <20 cP; stable under agitation/light stress.
3) Continuous capture for capacity surge.
PCC capture, inline dilution, virus inactivation harmonized with surge tanks. Outcome: +45% resin utilization, indistinguishable CQAs vs. batch capture, PPQ passed on first attempt.
