Astrum’s Porto Phase I Unit combines the security of a hospital-based environment with the efficiency of a dedicated clinical pharmacology facility. Managed by our own clinical team.
We provide end-to-end expertise across the full spectrum of early development studies
Launching an early-phase trial requires speed as much as scientific rigor. Portugal is recognized as one of the fastest approval environments in Europe for Phase I and first-in-human studies.
Regulatory review is conducted by INFARMED with a centralized ethics committee, avoiding delays linked to multiple local reviews.
Phase I studies in Portugal can often be approved in 6 weeks on average (31 days).
INFARMED has a strong reputation for responsiveness, clarity, and consistent guidance.
Approvals and inspections in Portugal are fully aligned with EMA, FDA, and ANVISA requirements, ensuring international acceptance.
This regulatory efficiency, combined with Astrum’s hospital-based infrastructure in Porto, means Sponsors can move from protocol submission to First participant in significantly shorter timelines — without compromising on quality or compliance.
Choosing Portugal for early-phase development offers Sponsors a combination of speed, safety, and global regulatory confidence that few European countries can match.
Average approval times for Phase I studies.
With our Porto Phase I Unit, Sponsors gain the confidence of a trusted, globally recognized site combined with the speed, flexibility, and expertise of a pan-European CRO.
