Apheresis Machines as Collection/Treatment Devices and Laboratory Equipment
COBE Spectra and Fenwal CS3000 were workhorses for plasma exchange, plasma collection, red cell exchange
Both had protocols for selective blood product collection
Both could be used to selectively concentrate or refine other collected products
Ex. Red cell removal from bone marrow collections in ABO mismatched transplants

General Rules of Design
The simpler the device:
More adaptable the device was
Products were more variable
Had fewer patient-protecting controls
Required operator skill
– Took longer to train staff
![Page 8: Validation and Qualification of New Equipment for Clinical Applications€¦ · Amicus and Optia, the New Generation Validation and Qualification of New Equipment for Clinical Applications](https://reader030.vdocuments.us/reader030/viewer/2022041000/5ebe7676a2c61c498b2f381b/html5/thumbnails/8.jpg)

Rules of Technologic Evolution
Devices became more sophisticated Computer programs were designed to run
specific protocols Defined protocols yield consistent products
Improvements were incremental with increasing software control and fewer operator interactions
Basic devices remained relatively stable
![Page 9: Validation and Qualification of New Equipment for Clinical Applications€¦ · Amicus and Optia, the New Generation Validation and Qualification of New Equipment for Clinical Applications](https://reader030.vdocuments.us/reader030/viewer/2022041000/5ebe7676a2c61c498b2f381b/html5/thumbnails/9.jpg)

Newer Devices Are Highly Engineered
Programming controls the run so that less operator intervention is needed
Higher precision in specific programs decrease adaptability
Patient protections are programmed in:
Air detectors to prevent air embolism
Limits on ACD infusion to the patient according to calculated blood volume to prevent Ca++ chelation problems
![Page 10: Validation and Qualification of New Equipment for Clinical Applications€¦ · Amicus and Optia, the New Generation Validation and Qualification of New Equipment for Clinical Applications](https://reader030.vdocuments.us/reader030/viewer/2022041000/5ebe7676a2c61c498b2f381b/html5/thumbnails/10.jpg)

Engineering Improvement
Spectra Optia is smaller, lighter than COBE Spectra
Kits and software packages are specific to purposes described
Amicus is smaller and lighter than CS 3000
Amicus and Spectra were developed for therapeutic plasma exchange, plasma collection
Specialized cellular collection programs were added later
![Page 11: Validation and Qualification of New Equipment for Clinical Applications€¦ · Amicus and Optia, the New Generation Validation and Qualification of New Equipment for Clinical Applications](https://reader030.vdocuments.us/reader030/viewer/2022041000/5ebe7676a2c61c498b2f381b/html5/thumbnails/11.jpg)

What Happens After the Retirement?
Will a single machine replace all the functions of the older machines?
What are the regulatory approvals on the newer devices?
What does each laboratory and treatment center need to do to qualify the new devices?
![Page 12: Validation and Qualification of New Equipment for Clinical Applications€¦ · Amicus and Optia, the New Generation Validation and Qualification of New Equipment for Clinical Applications](https://reader030.vdocuments.us/reader030/viewer/2022041000/5ebe7676a2c61c498b2f381b/html5/thumbnails/12.jpg)
12
Novel Uses Are Going to Different or Older Devices
There is no approved software control package in the Optia or Amicus for buffy coat refinement of bone marrow at this time
The COBE 2991 is still in service in many places
Newer devices, such as the Sepax 2 (Biosafe, Eysins, SW), can be used in labs where they are already in place – usually Cord Blood Banks
![Page 13: Validation and Qualification of New Equipment for Clinical Applications€¦ · Amicus and Optia, the New Generation Validation and Qualification of New Equipment for Clinical Applications](https://reader030.vdocuments.us/reader030/viewer/2022041000/5ebe7676a2c61c498b2f381b/html5/thumbnails/13.jpg)

Bloodworks NW Validation Plan
A carefully controlled “in process validation” was the practical format
Lab monitoring of each step informed progress of each collection
Data collected allowed us to formulate effective collection processes going forward
Spectra Optia was validated
![Page 15: Validation and Qualification of New Equipment for Clinical Applications€¦ · Amicus and Optia, the New Generation Validation and Qualification of New Equipment for Clinical Applications](https://reader030.vdocuments.us/reader030/viewer/2022041000/5ebe7676a2c61c498b2f381b/html5/thumbnails/15.jpg)
15
Validation Plan
Study the method of operation of the machine Electronic data readouts, operational details
Decide on the “must-haves” in the new machine Safety for the donor (check alarms) Sterility of product Viability of product Yield of apheresis run
Measure what operating parameters will change Anticoagulant strategy Time of run Product volume
![Page 16: Validation and Qualification of New Equipment for Clinical Applications€¦ · Amicus and Optia, the New Generation Validation and Qualification of New Equipment for Clinical Applications](https://reader030.vdocuments.us/reader030/viewer/2022041000/5ebe7676a2c61c498b2f381b/html5/thumbnails/16.jpg)

Validation Run Plans
The Performance Qualification can practically be done on patients or allogeneic donors with oversight and controls
Other centers have set up plans ̶ new device is used on patients or donors where multiple collections are planned
The new and test devices alternate days
Run unstimulated research donors first to verify approximate collection efficiencies, then CD34+ stimulated subjects
Number of procedures planned: 10 to 50
![Page 17: Validation and Qualification of New Equipment for Clinical Applications€¦ · Amicus and Optia, the New Generation Validation and Qualification of New Equipment for Clinical Applications](https://reader030.vdocuments.us/reader030/viewer/2022041000/5ebe7676a2c61c498b2f381b/html5/thumbnails/17.jpg)
17
A Sample from the collection bag was taken 2 hours into collection
CD34+ count was done; lab calculated the number of mL of product needed to fulfill the collection goal Assumption: the CD34+ content would be stable throughout
collection Collection time and liters of blood processed were
determined by this calculation
ACD only anticoagulant was used as per Optia instructions – no heparin, no aspirin

Optia Validation – Lessons Learned
Predictive CD34+ counts were very valuable
Very high white-count donors, such as NMDP donors, give slightly lower collection efficiencies
Investigators and transplant centers need to order “expected plasma volume” or “minimum plasma volume” instead of “add 200 mL plasma to product”
Orders that are based on volume (xx liters) run through the device are not predictive, need predictive formula

23
Amicus Product RBC and Platelet Content
ABO type mismatched allogeneic transplants request <20 mL ABO mismatched red blood cells (RBC)
Company instructions say to expect 15%
Experience of most centers using the device (my survey) reported average hematocrits of 8 to 12%
In a 200+ mL product this is approaching the 20 mL point of caution
Amicus is the most platelet-sparing of the devices
![Page 24: Validation and Qualification of New Equipment for Clinical Applications€¦ · Amicus and Optia, the New Generation Validation and Qualification of New Equipment for Clinical Applications](https://reader030.vdocuments.us/reader030/viewer/2022041000/5ebe7676a2c61c498b2f381b/html5/thumbnails/24.jpg)
24
Amicus Validation – Lessons Learned
Volume of blood processed/min apparently affects collection efficiency
Combination of ACD-A and heparin can be used, but higher flow rates are problematic
Platelets are spared
Hematocrits are higher than Optia products One large institution, not measuring directly,
estimated at 7 to 9%
Company information – expect 15%

25
Data Display Characteristics
At the end of the procedure FACT Standards require labeling of the bag with contents before takedown and disconnection from the donor
Amicus does not provide the readout of mL in product or final volume ACD-A
Product must be removed and weighed
ACD-A must be calculated
Optia provides data display with the above information on the Graphical User Interface

Requirements for Late Stage Clinical Trial or Licensed Products Raw Material
Qualification of personnel
Qualification process is described by contract
Continuous exchange of quality metrics between supplier and manufacturer
Quality Review of your collection operation – Site qualification – Regulatory status review of your facility – Technical assessment of IT system for speed
and privacy
Physical appearance of facility and patient comfort features
