Clean Room Supplier Value
Propositions for Cell and Gene
Here is
an example of how the Productivity Hub can help cleanroom purchasers make the
crucial decision as to who should be responsible for the systems to insure
cleanliness and containment. This
hub can be used by the supplier to present value propositions to best help the
purchaser meet these goals in each niche.
The
specific question is “How much of this responsibility should be that of the
Cleanroom supplier. This is the
company which furnishes walls, ceilings and HVAC’s.
Let’s
start with the buyer’s perspective.
We asked Barry Garfinkle for his thoughts.
Barry was formerly VP of biological sciences and strategy at Merck.
Previously he had roles relative to technology and quality and long
experience as a cleanroom buyer. Here are his thoughts.
The
buyers of clean rooms are changing from the large pharma clients to more and
more of the Contract Manufacturers and Startup Companies. goes from large
facilities to smaller flexible facilities where the manufacturing processes and
platforms are changing every month we need to consider adapting. The
knowledge base of the NEW and future clients is less and less from experience
and the demand for HELP is more and more likely to continue. Examples are
mRNA which suddenly during COVID emerged as a dominant technology. The
value of a BATCH changed from millions of $ to perhaps a billion (example
KEYTRUDA batch over 100K vials X $10,000/vial list price). This has
demanded companies reduce risk and utilize technology which before was too
expensive. Cell and Gene therapy often means a customized product which is
only good for one patient (batch size 1) and high cost, which then means the
companies need to figure out how to pivot from making 50 large batches/year to
hundreds! The cell and gene therapy products need to use VIRUSES
to alter genes in cells and viruses. Clean rooms now require new attributes
(containment, once through air, rapid turnover between products, etc. The
regulatory agencies are changing their expectations and requirements. The
players don’t have the expertise and want to CONTRACT for everything other than
discovery which they understand. Oh Yes, and Money is Expensive and
Tight.
Barry
has submitted a detailed listing of the tasks and concerns. It is linked below.
He
starts with regulatory concerns. Most of them affect the design of the HVAC
system and air quantity either directly or indirectly.
He then
points out the unique needs of CDMO/CMOs.
The need to avoid cross contamination between suites, to change from one
batch to another and flexibility to change out equipment are high priorities.
Cell and
gene therapies have their own unique challenges and require extensive mapping
and monitoring of contaminants on surfaces as well as those which are airborne.
The full analysis is liked below.

Supplier Categories
Value
Propositions for the room suppliers can fall in 3 categories.
·
Contractor
·
Solutions Collaborator
·
Solutions Provider
Contractor: The value proposition
is that the components and construction will meet all specifications and the
quality and delivery time will both be reasons to pay more than to a competitor.
Due to the high premium placed on fast-track completions this differential can
lead to 30% EBITDA.
But it
is hard to consistently achieve this level in cell and gene therapy where the
rooms are relatively small and there are many variables impacting cleanliness.
So, the purchasers are inclined to pay the most to the providers of
solutions. As Barry points out, the
CDMOs are seeking flexibility as well as ease of modification. So pre-designed
modules such as AES Faciliflex are an answer.
Solutions Collaborator: The room
supplier can collaborate with the purchaser and equipment suppliers to ensure
the design will meet the performance goals. The maximum EBITDA is for the room
supplier to take responsibility for the tasks he can do best. A strong case can
be made that the most capable entity to make decisions about air quantity,
purity, and distribution is the room supplier.
He also needs to be involved in decisions relative to decontamination,
isolation, particle measurement and other aspects which affect the room design
and operation.
Solutions Provider: Total
responsibility can be taken by a large A/E firm.
But when it comes to rapidly evolving technologies such as variable
airflow and continuous viable particulate measurement, the cell and gene room
provider has the opportunity to be the most knowledgeable.
So what
are the specific technologies which allow a cleanroom contractor to become the
alpha solutions collaborator?
The
answers are being addressed in the Hub.
Specific Technologies for Room

The
starting point is the basic contracting function.
The Hub has value propositions for AES Clean. One is based on a turnkey
approach where AES has its own wall and ceiling manufacturing facility and its
own construction force. Another is
a modular predesigned room.

Cell and gene technology is rapidly evolving.
The cleanroom firms which are best able to incorporate the latest
technology improvements will generate the highest EBITA and provide the most
value to the purchasers.
Variable Air Flow
One
rapidly developing technology is variable air flow with continuous particle
monitors. The air flow to a zone is
varied to keep particulate levels below a specified number.
The advantages are better contaminant control at peak periods, energy
savings in low periods, and faster recovery from events.
Here is the initial Hub coverage.

Particle Removal
Another
developing technology is particle removal. The truth is that there are only
rules of thumb when it comes to air changes per hour to meet
the particle limits of a given class of cleanroom.
There is controversy over the most penetrating particle size and
therefore the selection of HEPA or ULPA filters.
Coverage of this is provided at
The
selection of filters will vary as explained in this analysis. So, it requires
the knowledge of the cleanroom supplier to make sure the best decision is made.
Viable Particle Monitors
As Barry
points out the customers are very concerned about viable particles.
There is now a way to measure them continuously.

Since the air flow rates and particle concentrations are directly related, it
makes sense for the room supplier to be at least collaborating on the monitoring
system.
Isolators
Isolators and RABS involve changes in HVAC air flow patterns in addition to the
local air flows.

Flexibility
Barry
cites flexibility as one of the needs of CDMOs. Not only is there a need to add
equipment but in some cases to move equipment out for cleaning while a duplicate
has been moved in for current operation

If a
large piece of equipment such as a filter press is moved in and out of a room,
the room designer will have to supply additional space.
Decontamination
Cleanroom suppliers are tasked with removing the particles from the room. A
parallel activity is killing any viable organisms still remaining.
One of the options is the dry method which uses airborne H2O2 and
therefore depends on the HVAC system to some extent.
The cleanroom supplier can have a proactive role and optimize the VHP
use. He can also provide air locks with VHP.

Continuous Room Monitoring
Particle
monitors can be placed in strategic locations and air quality measured
continuously. Changes in equipment
function, clothing protocols, traffic patterns and other variables can be
immediately identified, and remediation action taken.

The room
designer should be a major collaborator and instrumental in determining monitor
locations. Periodic offsite monitoring can be performed simultaneous to checking
filter pressure drop, humidity, temperature and other parameters.
In
summary the Cleanroom supplier is best equipped to keep up with the rapidly
changing technology. These changes can have a significant effect on cell and
gene operations. So, a supplier who can provide them can maximize EBITDA.
