Frequently asked questions (FAQ)
What is Polpharma API CDMO?
We are the contract development and manufacturing arm of Polpharma API — an FDA-approved and EU-GMP-certified European developer and manufacturer with over 75 years of expertise. We develop and manufacture small-molecule and complex APIs, HP APIs, Payloads and Linkers for ADC and Oligonucleotides for pharmaceutical and biotechnology partners, handling everything from early clinical batches to full commercial supply on a single, integrated European site.
What services does Polpharma API CDMO provide?
We offer end-to-end CDMO services: process research and development, technology transfer, cGMP manufacturing, process validation, regulatory support, and commercial supply. We support programs through all clinical phases, registration, and commercial production — allowing your molecule to move smoothly from development to launch with one dedicated partner, on one site.
What types of molecules can Polpharma API CDMO handle?
We specialize in small-molecule and complex APIs, technically demanding compounds — including high-potent (up to OEB 6) compounds, payload-linkers for antibody-drug conjugate (ADC), and oligonucleotides. Our team combines deep synthetic chemistry expertise (such as cryogenic, hydrogenation, and organometallic reactions) with advanced high-containment handling and particle engineering.
Does Polpharma API CDMO support both clinical and commercial scale?
Yes. We take programs from clinical scale to commercial supply on a single site without changing hands. Our batch capacities range from kilo lab scale (up to 3 kg) through pilot plant quantities (up to 40 kg) to commercial production (30–800 kg), supported by more than 220 reactors from 5 to 6,300 liters.
Where are Polpharma API CDMO's facilities located?
We operate from an integrated European site in Starogard Gdański, Poland, co-locating R&D, kilo labs (including high-potency units), a pilot plant, and commercial production. Keeping development and manufacturing together on one site ensures smooth technology transfer and seamless collaboration.
What makes Polpharma API CDMO different?
We combine a quality-first, error-preventing mindset with a genuine, hands-on partnership approach. You will work directly with the scientists on your program, receive proactive updates, and stay with one accountable team from development through commercial supply. Everything is delivered on a single European site under one unified quality system.
How long does a CDMO project typically take to start delivering?
It depends on the chemistry. For shorter, non-complex routes, we typically move from contract to delivered product in about 4–6 months; for multistep, complex chemistry, roughly 10–12 months. Technology transfer and analytical familiarization begin early, and a dedicated project manager sets the timeline with the client up front.

.webp)
“Inexperienced or overstretched CDMOs can run into delays, deviations, and compliance issues that can jeopardize a project or regulatory submission. At Polpharma, we follow a zero-error approach, as demonstrated by over 30 successful audits and EU GMP certifications across all departments, which ensures processes are consistent and fully compliant. We help our clients stay aligned and keep projects on track from early trials to commercial launch through rigorous quality standards and transparent communication."
Frequently asked questions (FAQ)
Is Polpharma API CDMO FDA-approved?
Yes. Our site is FDA-approved, with successful inspections completed in 2004, 2009, 2012, 2015, and 2018. We are also regularly inspected by other major global regulatory authorities, including EMA/PIC-S members, Japan's PMDA, Brazil's ANVISA, and Korea's KFDA. Our GMP certificates are registered in the EudraGMP database.
What quality management system does Polpharma API CDMO use?
We operate a pharmaceutical quality system built in accordance with current cGMP and EU GMP Part II (ICH Q7) guidelines. Our independent Quality unit maintains final authority on all quality decisions, quality risk management follows ICH Q9, and deviations, CAPAs, change controls, complaints, and product reviews are managed using TrackWise.
How does Polpharma API CDMO manage deviations and CAPA?
We register every deviation in TrackWise, communicate it immediately to the customer and project teams, and investigate to determine impact and root cause. We keep the customer informed about the status of the investigative activities; the customer has the opportunity to participate in these activities, approves the summary, and jointly defines the CAPA. We assign, implement, and verify corrective and preventive actions, while monitoring quality trends monthly across all operations.
Can clients audit Polpharma API CDMO and attend regulatory inspections?
Yes. We welcome a full quality audit from clients once per calendar year with 30 days' notice, and accommodate immediate for-cause audits whenever necessary. We keep you informed of, and invite you to attend, regulatory inspections involving your product.
How does Polpharma API CDMO ensure data integrity and record retention?
We maintain validated computerized systems with role-based access, audit trails, automated backups, and controlled data changes under a formal data integrity SOP. We retain batch documentation for at least eight years and can return project-specific records upon request under our Quality Agreement.
What does EU–US mutual recognition mean for my ANDA filing?
Our site is regularly inspected by the Polish Main Pharmaceutical Inspectorate, a PIC/S member with mutual recognition with the US FDA. For ANDA filings, the FDA accepts GMP inspection reports issued by the Polish authority, generally eliminating the need for a separate facility inspection and reducing regulatory timelines.
What environmental and sustainability credentials does Polpharma API hold?
We hold ISO 14001 (environmental management) and ISO 45001 (occupational health and safety) certifications, alongside an EcoVadis Silver rating (74/100). Our laboratory practices align with ISO/IEC 17025, and we operate under a comprehensive Group Environmental Policy and Sustainable Development Strategy.

Frequently asked questions (FAQ)
How does Polpharma API CDMO communicate with clients during a project?
We prioritize clear, proactive communication throughout every project. A dedicated project manager leads weekly or bi-weekly meetings and provides written summaries covering progress, upcoming activities, and risk management so you always know where your project stands.
Will I have direct access to the scientists working on my molecule?
Yes. You work directly with the scientists and project leads responsible for your molecule, rather than navigating sales layers. Because our R&D, kilo labs, pilot plant, and commercial production sit on a single site, answers come straight from the experts performing the work.
How does Polpharma API CDMO handle delays or unexpected problems?
We flag challenges early. If raw material delays or unexpected results threaten the project timeline, your project manager will promptly present transparent solutions and mitigation options. We focus on active problem solving and keeping decisions firmly in your hands.
How does technology transfer work at Polpharma API CDMO?
Technology transfer begins early with analytical method transfer and process familiarization. With development and commercial manufacturing co-located on one site, knowledge transfers seamlessly between teams. Your project manager will establish a tailored, efficient tech transfer plan right from the outset.
What contractual and quality agreements does Polpharma API CDMO put in place?
We establish a Quality Technical Agreement (typically within 30 days of project signing) to clearly outline responsibilities. Project parameters — including communication schedules, document sharing, audits, and confidentiality — are defined upfront and managed by your assigned project manager.
How does Polpharma API CDMO keep a project on track after the kickoff phase?
We actively steer projects to prevent timeline drift. Our project managers build contingency plans for key risks, review project scope against real-time laboratory data to avoid scope creep, and adjust courses early to keep your project moving smoothly toward final delivery.
