CMC expertise built over 20+ years

CMC support for Biotech from research to commercial stage

Scientific innovation is a strong starting point, but it only creates value when it can be developed, manufactured, and positioned to succeed. ATBio-Consulting helps early-stage biotechs turn drug candidates into robust, manufacturable, and regulatory-ready development programs. We provide end-to-end CMC expertise, from manufacturability assessment and CDMO selection to phase-appropriate clinical supply strategies.

Plan your next CMC strategy

I am an experienced CMC consultant with a strong track record in advancing innovative drugs from concept to clinic and commercial launch. As founder of ATBio-consulting, I supports biotech startups and growing biopharma companies in transforming breakthrough science into development-ready, high-quality drug candidates.

Before founding ATBio-consulting, I held key CMC leadership roles at several pioneering biotech companies, (UCB Pharma, Ablynx, Vivet Therapeutics, and ExeVir Bio) where I successfully advanced multiple programs to clinical milestones (e.g. VTX081, XVR011) up to commercial stage (Brivaracetam/Briviact®, Caplacizumab/Cablivi®).

Recognized for my pragmatic, collaborative approach, I help Biotech teams build solid, investor-ready CMC foundations and align science, strategy, and execution to accelerate development timelines and enhance value creation.

How We Support Your CMC Development ?

CMC drug development plan

ATBio-Consulting builds tailored CMC development plans that give biotech startups a clear and credible path from candidate selection to Phase 1. Each plan defines key activities, costs, and timelines, helping investors assess feasibility and value.

Supported by strong CMC expertise and trusted CRO and CDMO partners, our plans are realistic, phase-appropriate, and aligned with regulatory expectations to support seed and Series A fundraising.

Manufacturability assessment & lead candidates selection

Selecting the right drug candidate requires more than biological activity; it must also be manufacturable, stable, and developable. ATBio-Consulting leads developability and manufacturability assessments through a network of specialized CROs and analytical partners, using a science-driven, risk-based approach to identify technical risks early and guide candidate selection.

Typical activities include :

• Sequence and structure analysis to identify PTM and aggregation risks.
• Expression and purification feasibility studies.
• Formulation and stability screenings under stress conditions.
• Aggregation and solubility assessments.
• Specificity and off-target interaction reviews.

Results are summarized in a comparative developability matrix to support data-driven selection of robust, manufacturable lead candidates.

CRO/CDMO selection

Choosing the right development and manufacturing partners is key to moving a preclinical program into the clinic. ATBio-Consulting supports early-stage biotech companies in identifying and selecting CROs and CDMOs that match their scientific, technical, and strategic needs.

Through an independent and objective process, we help to :

• Define clear project scopes and selection criteria.
• Assess technical capabilities, quality systems, and track records.
• Manage the RFP process by comparing cost, timelines, and risk.
• Support final partner selection and contracting.

This ensures your program is placed with the right partners, reducing risk and keeping development on track.

CMC Project Management

Drug development is a demanding journey that requires tight coordination between science, strategy, and execution. Success depends not only on innovation, but on the ability to align internal teams, CROs, CDMOs, clinicians, and regulators. At ATBio-Consulting, we bring structure and clarity to complex development programs through rigorous project management, clear communication, and proactive riskcontrol, keeping timelines realistic and milestones on track.

Our expertise includes :

• Definition of TPP and QTPP.
• Phase-appropriate assessment of CQAs and CPPs.
• Timelines and budget management.
• Cross-functional coordination.
• CRO/CDMO oversight.
• Risk assessment and mitigation.
• Support for regulatory meetings and Module 3 preparation.

Testimonials

“Antoine is one of the best experts in the clinical development of VHHs. He not only defines optimal clinical and regulatory strategies, but also performs in-depth reviews of CDMO proposals to ensure the right experience, capacities, and partnerships are in place to translate drug substance into a suitable drug product for clinical trials.

I had the opportunity to work closely with Antoine both at BerkingTheranostics, a startup developing radioligands for the diagnosis and treatment of solid tumors, and in an academic setting supporting European grant applications in antiviral VHH clinical development. Hisclarity, rigor, and generosity in explaining complex topics made the collaboration extremely valuable and educational.”

Dr. Alejandro Rojas

CEO of Berking BioScience and berking Theranostics, Principal investigator AustralUniversity of Chile

"Antoine supported TargED as a consultant acting as VP External Manufacturing, contributing to the definition of a regulatory-compliant CMC strategy.

Alongside supporting the establishment of the manufacturing process for early stage clinical trials and initiating the identification of CQAs (Critical Quality Attributes) shaping the product release specifications, he brought a forward-looking perspective to platform selection, supporting the evaluation of options for ensuring long-term manufacturability and scalability."

Dr. Kristof Vercruysse

CEO and Co-Founder at TargED Biopharmaceuticals

“Antoine brings solid CMC strategic insight and a broad, relevant industry network. His guidance and experience were very helpful in selecting the right CDMO, and his project management skills strongly support the program’s progress. He combines hands-on, practical execution with a clear, big-picture roadmap for effective CMC development.”
