Product Information:

Evidentic offers repackaged finished pharmaceutical products (e.g RMP/RLD). We refer to the repackaged RMP/RLD products synonymously as drug aliquots or aRMP, or short: aliquots.

We offer batches of original drug aliquots in low-binding Eppendorf tubes for research use only. We provide licence-free drug aliquots with long, short or even “negative shelf life” by storing the products at recommended temperatures (either 2-8°C or -80°C) and ensuring fully functional molecules for research purposes.

As ‘raw material’ for the production of drug aliquots, Evidentic sources RMP from the European (EU) market. As a licensed pharmaceutical wholesaler, Evidentic is committed to Good Distribution Practice (GDP) compliance with respect to the procurement, storage and shipment of RMP.
Drug aliquots are manufactured by repackaging RMP in a qualified laboratory. The aliquotation process is performed under a quality and manufacturing agreement between Evidentic and the contract manufacturer. Repackaging of RMP includes the following steps: opening the secondary and primary RMP containers and transferring the specified volumes of RMP into an Eppendorf 0.5 ml low-binding (or similar) tube. If the RMP is a lyophilized powder and not a highly concentrated solution, reconstitute the RMP according to the original manufacturer’s instructions and then aliquot as a highly concentrated solution.
For identification purposes, drug aliquots are labeled with the date of aliquoting, the original lot number of the RMP, the original expiration date of the RMP, the name of the active ingredient (INN), and a unique identification code.
Immediately after aliquoting, drug aliquots are stored at either 2-8 °C or -86 °C for long-term storage. All drug aliquots stored at 2-8 °C are transferred to -86 °C at least two weeks before the expiration date of the original RLD/RMP is reached. Further quality or functional testing are not performed on the drug aliquots.

Mechanism of Action (MoA)

Ibritumomab tiuxetan is a recombinant murine IgG1 kappa monoclonal antibody specific for the B-cell antigen CD20. Ibritumomab tiuxetan targets the antigen CD20 which is located on the surface of malignant and normal B-lymphocytes. During B-cell maturation, CD20 is first expressed in the midstage of B-lymphoblast (pre-B-cell), and is lost during the final stage of B-cell maturation to plasma cells. It is not shed from the cell surface and does not internalise on antibody binding.
