What to evaluate for Oligo/ASO programs
Both Bachem and ST Pharm qualify as Oligo/ASO CDMOs. When choosing between them for Oligo/ASO programs, weigh these four dimensions specifically — each carries through to the side-by-side scorecard above.
Synthesis scale
Match synthesizer scale (mmol to mol) to your clinical and commercial demand, and confirm the CDMO can scale without shifting the impurity profile.
Chemistry & conjugation
Confirm experience with your backbone and modifications (phosphorothioate, 2'-MOE/F) and any conjugation (GalNAc, lipid) your molecule requires.
Purity & analytics
Full-length product, deletion/addition impurities, and residual metals drive release. Look for established orthogonal analytics.
Regulatory track record
Cross-check FDA 483 history and EMA/MHRA GMP coverage — both shown above and on each profile.
Frequently asked: Bachem vs ST Pharm
Which has the stronger FDA inspection record, Bachem or ST Pharm?
Bachem has 1 FDA inspection on record (NAI 0 / VAI 1 / OAI 0) and 0 warning letters. ST Pharm has 2 FDA inspections on record (NAI 0 / VAI 1 / OAI 1) and 0 warning letters.
How do Bachem and ST Pharm compare on European GMP coverage?
Bachem holds 0 active EMA GMP certificates and 0 MHRA / UK certificates. ST Pharm holds 4 active EMA GMP certificates and 0 MHRA / UK certificates. Use these counts as a proxy for the breadth of each CDMO's European regulatory footprint.
Which is better for Oligo/ASO manufacturing — Bachem or ST Pharm?
Both Bachem and ST Pharm are tagged as Oligo/ASO CDMOs in our directory, so both are credible options for Oligo/ASO programs. The most important differentiator for Oligo/ASO selection is typically synthesis scale: Match synthesizer scale (mmol to mol) to your clinical and commercial demand, and confirm the CDMO can scale without shifting the impurity profile. Review each CDMO's profile and inspection record before shortlisting.
What does the Signal Score gap mean in practice?
Bachem carries a Signal Score of 84/100 and ST Pharm carries 73/100 — a meaningful lead for Bachem. The Signal Score combines quality (FDA inspections + EMA/MHRA GMP), operational performance, financial stability, and capacity intelligence. CDMOs cannot pay to influence their score.
