Why was it done?

One of the most important challenges we currently face is the increase of clinical trials (CTs) including CBMPs. These drugs require special storage, preparation, delivery and administration; so developing standard operating procedures (SOPs) and ensuring proper coordination between all professionals involved, including pharmacists, is essential.

What was done?

Management of cell-based medicinal products (CBMPs) was protocolised in an onco-haematology clinical trials unit.

How was it done?

Pharmacists, doctors and nurses participate in a multidisciplinary team to standardise CBMPs handling. The following protocol was agreed:
1.The entire multidisciplinary team is notified when a CBMP prescription is planned to ensure proper coordination.
2.The CBMP is manufactured by the CT sponsor. Then, it is transferred to the blood bank for cryopreservation. CBMPs usually require a temperature between -80ºC and -200ºC and expire in some weeks.
3.Before CBMP administration, patients undergo lymphodepletion. The lymphodepletion regimen is performed according to the CT protocol or arranged between medical and pharmacy teams. Chemotherapy, serum therapy and antiemetic regimen are discussed and specified.
4.Once the treatment is prescribed, it is verified by a pharmacist who ensures its suitability.
5.On the infusion day, the blood bank delivers the CBMP. Then, a pharmacist checks if it arrives in proper condition and it is defrosted. The pharmacy department reconditions the CBMP in another infusion bag or syringe if required. This is the most critical point because CBMP expires after some minutes of defrosting, requiring extensive coordination.
6.CBMP is administered according to the CT protocol.

What has been achieved?

72 patients were recruited in 15 CT. 8 of them use as CBMP Chimeric Antigen Receptor T-Cells (CAR-T-CELLS), 4 Specific Peptide-Enhanced Affinity Receptor T-Cells (SPEAR-T-CELLS), 2 Tumour-Infiltrating Lymphocytes (TILs) and one cytokine-stimulated Natural-Killer-Cells (CS-NK-CELLS). Seven assays are intended for haematological neoplasms and eight for solid malignant neoplasms. One assay requires CBMP syringe reconditioning in the pharmacy department.
The described process optimises CBMPs handling, avoids delays in administration and reduces the risk of misuse.

What next?

CBMPs represent a novel therapy, and pharmacists have an essential role in developing new procedures to incorporate them into clinical practice. This protocol may be helpful for other centres to implement guidelines to work with CBMPs.

EAHP Forum

All the EAHP team is working on providing a Forum that can help connect all the members in Conversations and Groups to talk about important matters for the European Hospital Pharmacist.

The Forum will be accessible for all the EAHP members, you don’t have to create a new account to browse and participate.

Conversations and groups

The Conversations will be moderated by our team to provide documents and relevant topics for the community.

The Groups will connect all members that share a category. Members who work on the same assocation, on the same hospital, that have the same role, etc.

Stay tuned for the realase of the forum. Soon on EAHP.
