Clinical trials without pain

For over 30 years ADAllen Pharma has sourced clinical trial comparator drugs for major Pharma and contract research organizations (CROs) in a multitude of sites across the world. Sourcing comparator drugs for international clinical trials is a complex and unique process that requires meticulous planning and oversight on our part in order for us to meet the specific requirements of our clients. They include many of the top ten pharmaceutical companies as well as biotech companies, CROs, packaging companies, sponsors and hospitals. Finally, we work very closely alongside our suppliers to ensure any potential sourcing issues are overcome.

With new regulatory requirements and an ever-changing life science landscape, we strive to keep abreast of developments and be the leaders in our field for comparator procurement, ensuring that whatever the size of order − from sample packs to high value orders − they are all treated with the same amount of care.

Products and services

In line with the ever-changing environment we are now able to offer the following new services to our customers.

Packaging and distribution

We are now able to offer packaging and distribution services so that our customers are able to use us as a one-stop-shop for all their requirements.

Product distribution for new and mature products

We also are now able to offer product distribution for new and mature products that are becoming too costly for manufacturers to deal with directly. Offering older products and new small-volume products, which pharmaceutical manufacturers are finding expensive to distribute and handle, we are now in a position to offer a very competitive service and price.

Manufacture of special preparations

We have joined forces with a manufacturer of special preparations and are able to provide special formulations at a reasonable cost and delivery. Our pricing for these products is transparent and we aim to quote for preparations within 48 hours of receipt.

For the personal touch in the global pharmaceutical industry and with over 30 years of experience in the field of pharmaceutical procurement, ADAllen Pharma strives to provide an exceptional service to all our clients by supporting them at every phase of their clinical trials.
