Samsung Biologics vs WuXi Biologics: CDMO Comparison
Side-by-side comparison of Samsung Biologics and WuXi Biologics on independent FDA inspections, EMA and MHRA GMP certificates, clinical-program activity, and CDMO Signal Score. Data sourced from FDA, EMA EudraGMDP, MHRA GMDP, and ClinicalTrials.gov.
Key differences
- WuXi Biologics holds 3 active EMA GMP certificates; Samsung Biologics does not appear in EudraGMDP.
- WuXi Biologics maintains 1 MHRA / UK GMP certificate; Samsung Biologics does not.
- Composite Signal Score: WuXi Biologics 84/100 vs Samsung Biologics 68/100 — a 15-point gap reflecting the combined quality, capacity and financial signal.
On a 13-modality CDMO landscape, both Samsung Biologics and WuXi Biologics qualify as ADC manufacturers; WuXi Biologics carries the higher composite Signal Score for ADC programs in this comparison.
What to evaluate for ADC programs
Both Samsung Biologics and WuXi Biologics qualify as ADC CDMOs. When choosing between them for ADC programs, weigh these four dimensions specifically — each carries through to the side-by-side scorecard above.
HPAPI containment
Look for OEB-5 (sub-microgram occupational exposure band) suites for handling cytotoxic payloads end-to-end. Containment maturity is the floor for credible commercial ADC work.
Linker-payload chemistry on file
Match the CDMO's payload + linker experience to your program. MMAE / vc-MMAE is the most common; PBDs, calicheamicin, Dxd-class topoI inhibitors, and TLR agonists each carry distinct handling and analytical demands.
Commercial bioconjugation track record
Has the CDMO conjugated a commercially-approved ADC? Track record on Polivy, Padcev, Trodelvy, Enhertu, Tivdak, Elahere, Adcetris, Mylotarg, Besponsa, Lumoxiti, Blenrep, etc. is a strong qualifying signal.
Integrated DS + DP
Bioconjugation produces ADC drug substance; you'll also need sterile fill-finish for drug product. Confirm whether the CDMO covers both or partners — both routes work, but integrated is faster on transfer.
Frequently asked: Samsung Biologics vs WuXi Biologics
How do Samsung Biologics and WuXi Biologics compare on European GMP coverage?
Samsung Biologics holds 0 active EMA GMP certificates and 0 MHRA / UK certificates. WuXi Biologics holds 3 active EMA GMP certificates and 1 MHRA / UK certificate. Use these counts as a proxy for the breadth of each CDMO's European regulatory footprint.
Which is better for ADC manufacturing — Samsung Biologics or WuXi Biologics?
Both Samsung Biologics and WuXi Biologics are tagged as ADC CDMOs in our directory, so both are credible options for ADC programs. The most important differentiator for ADC selection is typically hpapi containment: Look for OEB-5 (sub-microgram occupational exposure band) suites for handling cytotoxic payloads end-to-end. Containment maturity is the floor for credible commercial ADC work. Review each CDMO's profile and inspection record before shortlisting.
What does the Signal Score gap mean in practice?
Samsung Biologics carries a Signal Score of 68/100 and WuXi Biologics carries 84/100 — a meaningful lead for WuXi Biologics. The Signal Score combines quality (FDA inspections + EMA/MHRA GMP), operational performance, financial stability, and capacity intelligence. CDMOs cannot pay to influence their score.
