Case Study 1: Revolutionizing mRNA-LNP Delivery for Rare Genetic Disorders

Client Challenge:

A mid-sized biotech firm developing an mRNA-based therapy for a rare neuromuscular disorder faced persistent hurdles in LNP formulation. Their initial platform suffered from low encapsulation efficiency (below 70%), inconsistent potency, and off-target delivery to the liver, delaying their IND submission by over a year. Regulatory feedback highlighted the need for enhanced targeting and scalability to support Phase 1 trials.

Our Approach:

At BioAI Consulting, we led a comprehensive overhaul of their mRNA-LNP platform. Starting with proprietary optimization of ionizable lipids and PEG components, we integrated antibody conjugation for muscle-specific targeting. We applied Quality by Design (QbD) principles to redesign the manufacturing process, scaling from lab-scale microfluidics to 50L GMP production. This included rigorous DOE (Design of Experiments) to fine-tune parameters like pH, lipid ratios, and mixing speeds, ensuring reproducibility. We also facilitated seamless tech transfer to a leading CDMO, incorporating real-time analytics for in-process monitoring.

Results and Impact:

The revamped platform achieved 95% encapsulation efficiency and a 12x improvement in targeted delivery, reducing off-target effects by 80%. This propelled the program through IND approval in just 6 months, enabling a successful Phase 1 trial with no safety signals. The client saved an estimated $15M in development costs and accelerated their timeline to market by 18 months. Today, this therapy is advancing to Phase 2, positioning the client as a leader in extrahepatic mRNA applications.

Case Study 2: Scaling AAV Production for Ocular Gene Therapy Breakthrough

Client Challenge:

An emerging gene therapy startup specializing in AAV-based treatments for inherited retinal diseases struggled with low yields in their upstream process. Using traditional HEK293 adherent cultures, they could only produce 10^12 vg/L, far below what's needed for commercial viability. Post-pivotal changes risked comparability issues, threatening their EMA and FDA submissions for a Phase 3 program.

Our Approach:

We spearheaded a full lifecycle intensification strategy, transitioning from adherent to suspension-based HEK293 systems with optimized transfection reagents. Leveraging our expertise in serotypes AAV2 and AAV9, we implemented fed-batch bioreactors at 200L scale, incorporating novel media formulations and perfusion techniques. Comparability protocols were designed with advanced analytics (e.g., ddPCR for full/empty capsid ratios and HPLC for purity), ensuring alignment with ICH Q5E guidelines. We managed PPQ campaigns end-to-end, from upstream optimization to downstream purification using affinity chromatography and final fill-finish.

Results and Impact:

Yields skyrocketed to 10^14 vg/L—a 100-fold increase—while maintaining >95% full capsids and potency. The comparability data satisfied regulators, supporting a rolling BLA submission without delays. The client reduced manufacturing costs by 60% per dose, enabling broader patient access. This project not only secured $200M in Series C funding but also fast-tracked the therapy to commercial launch, treating thousands with vision-restoring potential.

Case Study 3: Optimizing Lentiviral Vectors for Next-Gen CAR-T Therapies

Client Challenge:

A global pharma company advancing an LVV-enabled CAR-T program for solid tumors encountered scalability bottlenecks. Their third-generation LVV process yielded inconsistent infectious titers (around 10^7 TU/mL), with genomic instability issues during scale-up from 10L to 500L bioreactors. This jeopardized their tech transfer to CDMOs and risked failing PPQ validation, stalling multiple IND filings across the US and EU.

Our Approach:

Drawing on our deep LVV expertise, we re-engineered the platform with transient transfection enhancements and novel envelope proteins for improved transduction efficiency. We scaled to 2000L stirred-tank bioreactors using single-use technologies, implementing process controls like online pH/DO monitoring and harvest optimization. Validation included risk-based assessments per FDA's QRM framework, with authored CMC sections for regulatory dossiers. We also integrated potency assays to ensure genomic integrity, reducing truncations by 90%.

Results and Impact:

Infectious titers reached 10^9 TU/mL consistently, with a 15x potency boost that enhanced CAR-T cell expansion. The program cleared PPQ in record time, supporting three successful INDs and a Phase 2 trial initiation. Manufacturing efficiency improved by 70%, cutting costs and enabling the client to expand their pipeline to in-vivo applications. This success drew partnerships with top oncology firms, accelerating therapies that could transform outcomes for refractory cancer patients.

Case Study 4: Integrated CMC Strategy for Multi-Modality Platform (mRNA-LNP + AAV Hybrid)

Client Challenge:

A venture-backed innovator combining mRNA-LNP with AAV for CRISPR gene editing faced cross-modality integration issues. Their hybrid system showed variable editing efficiency (under 40%) and manufacturing impurities, complicating regulatory pathways for a liver-targeted therapy. With looming Phase 1 deadlines, they needed a unified CMC roadmap to de-risk scale-up and ensure BLA readiness.

Our Approach:

We crafted a bespoke strategy merging our mRNA-LNP and AAV proficiencies. This involved co-optimization of LNP formulations for AAV co-delivery, using ligand conjugation for enhanced hepatic targeting. Process development spanned from R&D to PPQ, with tech transfers to dual CDMOs under GMP. We employed advanced modeling for yield predictions and executed bridging studies to validate changes, authoring comprehensive CMC modules for FDA/EMA alignment.

Results and Impact:

Editing efficiency surged to 85%, with 8x higher potency in base editing applications. The integrated platform supported a seamless IND and Phase 1 readout, attracting $150M in acquisitions interest. By streamlining operations, we shaved 24 months off the development timeline, delivering a first-in-class
