Drug Substance & Drug Product Manufacturing Service

Comprehensive Manufacturing Solutions from API to Final Formulation

As the biotechnology sector continues to innovate with complex biologics and next-generation therapeutic antibodies, the need for integrated manufacturing solutions encompassing both drug substance (DS) and drug product (DP) is more crucial than ever. At Creative Biolabs, we provide end-to-end DS and DP manufacturing services designed to support projects from early-phase material supply through late-stage commercial readiness. With a robust infrastructure and deep regulatory insight, we enable seamless transitions between upstream production, downstream purification, and final product fill-finish.

Our Distinctive Manufacturing Platforms – Built for Flexibility and Speed

Creative Biolabs has established purpose-built platforms to accommodate the unique characteristics of biologic drug development. Our modular and scalable manufacturing systems are engineered for flexibility, offering both non-GMP pilot scale runs for feasibility or tox studies and GMP-compliant production suites for commercial manufacturing.

Our core manufacturing platforms include:

  • Single-Use Bioreactor Systems (SUBs): Ideal for microbial or mammalian expression, ranging from 2 L to 2,000 L scale.
  • Closed-System Processing: Minimizes cross-contamination risk while improving operational efficiency for aseptic production.
  • Integrated DS-to-DP Transition Modules: Custom-designed to connect downstream purification directly with formulation and filling units.
  • Automated Filling Systems: Suitable for both liquid and lyophilized products in vials, prefilled syringes, or cartridges.

These platforms are fully adaptable to a variety of modalities including monoclonal antibodies (mAbs), fusion proteins, bispecifics, antibody-drug conjugates (ADCs), and other recombinant biologics.

Advanced Technologies Supporting Manufacturing Precision

To ensure batch consistency and product integrity, Creative Biolabs incorporates a range of advanced technologies across DS and DP production stages:

  • High-Performance Downstream Purification: Multi-step chromatography (Protein A, ion-exchange, HIC, SEC) and tangential flow filtration (TFF) systems tailored for target purity and yield optimization.
  • Inline PAT (Process Analytical Technology): Real-time monitoring of critical parameters during fermentation and purification to enable continuous process control.
  • Formulation Engineering: Development and optimization of robust formulations to ensure product stability, bioactivity, and delivery compatibility.
  • Lyophilization Development & Cycle Optimization: Freeze-drying protocols for DP stabilization with precise control over freezing, drying, and sealing conditions.
  • Sterile Fill-Finish: Aseptic filling performed under strict Grade A/B environments with fill volume accuracy and container closure integrity testing.

Each process step is governed by quality systems compliant with ICH, FDA, EMA, and WHO regulatory frameworks.

Streamlined Manufacturing Workflow – Phase-Appropriate and Scalable

Our manufacturing workflow is designed to provide clarity and control at every step:

1. Initial Project Evaluation: Comprehensive review of molecular properties, manufacturing needs, and regulatory phase.

2. Tech Transfer & Process Development: Translation of lab-scale protocols to manufacturing scale, including process characterization.

3. Upstream Cell Culture/Fermentation: Cell line expansion, fed-batch or perfusion culture under controlled parameters.

4. Downstream Purification: Multi-step purification yielding DS with desired purity and quality attributes.

5. Formulation and DP Preparation: Buffer exchange, stabilizer addition, and preformulation studies for DP.

6. Fill-Finish and Packaging: Final filling into primary containers, visual inspection, labeling, and secondary packaging.

7. QA/QC and Batch Release: GMP-compliant batch review, testing, and certification of CoAs and batch records.

Frequently Asked Questions

Q1: Can Creative Biolabs manufacture both non-GMP and GMP batches for my antibody product?

A1: Yes, we offer both non-GMP batches for R&D or tox studies, and full GMP-compliant batches for commercial use. Transitions between the two are fully managed.

Q2: What container types can you support for drug product filling?

A2: We support filling into glass vials, prefilled syringes (PFS), cartridges, and lyophilized formats. Container selection can be customized based on product profile and delivery route.

Q3: Do you offer formulation development as part of DP manufacturing?

A3: Absolutely. We provide formulation screening, excipient compatibility studies, and stress testing to ensure DP stability and efficacy.

Q4: Can I transfer an existing DS process to your site?

A4: Yes, we have extensive experience in process transfer and optimization. Our team will work closely with you to ensure seamless tech transfer and scale-up.
