Cell and Gene Supply Chain Services

Only Marken can seamlessly guide your cell and gene therapies through each stage of the pharmaceutical journey.

To ensure cell and gene therapies are brought to market successfully, pharma and biotech companies must address logistical complexities within the clinical supply chain, which requires specialized solutions, industry expertise and a rigorous control process coupled with advanced technology.

Marken’s unique cell and gene supply chain offering includes:

Cell and Gene Therapy Development

Sponsor or IP Holder

Sponsor or IP (Investigational Product) license holder with copyrights and confidential formulation or proprietary manufacturing process knowledge contracts out supply chain functions.

Collection Kit

A vendor, such as Marken, assembles sample collection kits containing all the materials a technician needs to collect apheresis/leukapheresis or tissue samples, etc., in accordance with the study protocol.

Patient Visits Investigator or Physician

A physician or specialist enrolls the patient in a clinical trial or prescribes a commercially approved cell and gene therapy. The doctor then sends the patient to a clinic to provide their samples.

Apheresis Center or Clinic

At the clinic, the patient provides their cellular material, either blood or tissue. It is then shipped to a diagnostic lab or directly to a manufacturing facility, often at 2˚C to 8˚C or controlled room temperature. Cells lose viability quickly, so the next leg of the journey is usually the most time sensitive — 24 hours or less.

Diagnostic Lab

In some cases, when a manufacturer lacks the appropriate lab analysis capabilities in-house, the material goes to a separate diagnostic lab to be analyzed for cell count and other properties or for further processing before being sent to the manufacturing facility.

CMO or Manufacturer

With the addition of special proteins or viral vectors, the patient’s cells are modified to make the personalized medicine. This unique, proprietary manufacturing process could take four to 45 days.

Viral Vectors Manufacturer

When viral vectors such as retroviruses, lentivirus or adenovirus are used to house cell and gene therapies, these are mass produced by cell culture ahead of time. This manufacturing process can require a 12- to 18-month lead time.

Cryo Storage or Depot

Autologus drugs intended for the one person who supplied the original sample are quickly shipped back to that person under strict climate-controlled conditions, typically cryogenically at -150˚C or colder, sometimes in dry ice. Allogenic drugs made to treat a select group of patients with the same disease must be carefully stored at a depot until appropriate patients can be recruited into the trial or are prescribed the drug.

Home Healthcare

Administration of cell and gene therapies nearly always occurs in a hospital setting. Once patients leave the hospital, home healthcare technicians may be employed to assess the patient on follow-up, draw labs and deliver acute-care medicines like rescue meds or steroids.


The personalized cell and gene therapy is administered to the patient.
