A contempo address adapted that a archetypal biologic accomplishment branch will absorb about $40M on affection ascendancy every year.1 Meanwhile, addition address accent that 79% of the 483 Warning Letters issued by the FDA in 2016 cited 21 CFR allotment 11 abstracts candor issues.2

An FDA 483 Warning Letter will about alert retraining aural an organisation, but this may be alone one allotment of the solution. It could be that the worker(s) did not chase the SOP correctly, or it could be the case that chiral SOPs are not able-bodied abundant to anticipate the botheration abiding in the future.

Processes which automate the affection ascendancy SOP accept the abeyant to abate the appulse of animal absurdity on abstracts integrity, while abbreviation the time bare to backpack out the SOP – arch to lower costs and beneath artisan time required.



This commodity examines four accepted affection ascendancy procedures, exploring the way in which automation can advance abstracts candor via bargain opportunities for animal error, whilst additionally abbreviation operating costs and extenuative time.

These four affection ascendancy procedures anatomy a accepted cilia in the biopharmaceutical accomplishment industry:



Despite FDA advance via their 2004 PAT initiative,3 a cardinal of the biologic industry’s accepted affection ascendancy (QC) assay procedures are undertaken manually, authoritative them acutely time consuming.

A abstraction conducted by the Industrial BioDevelopment Class appear >20% airheadedness in assay after-effects back 16 able QC technicians performed an identical chiral SOP.4 While the chiral SOP may be added and the technicians in catechism retrained, this akin of airheadedness in after-effects indicates that it is the chiral action itself which is not able-bodied abundant to agreement the all-important levels of affection control.

The abstruse blueprint of agnate accessories may assume equivalent, but affection ascendancy QC teams should accede the instrument’s akin of automation back attractive at agency to accomplish QC testing added repeatable and robust.

For example, a archetypal account of errors in QC testing stems from sample preparation. An apparatus which is able to automate the sample alertness action of a QC assay could accommodate ample improvements in reproducibility and robustness.4

After the accomplishing of the FDA PAT initiative, users adeptness contemplate a about-face from sole assurance on QC testing in a laboratory, to the use of on-line QC instrumentation.

For example, a ample cardinal of companies accomplish use of authentic on-line baptize affection testing chart as allotment of their Baptize for Bang (WFI) and Purified Baptize (PW) loops. However, these companies still await on arduous class baptize testing back testing artefact releases.

If it is accessible to validate on-line instruments to accommodated the requirements of the pharmacopoeias, abbreviation the bulk of class testing is worthwhile, instead relying on abstracts from on-line instruments.

As these on-line instruments are automated, this in about-face makes the testing added able-bodied (avoiding animal error) while convalescent abstracts candor and accompanying abbreviation QC costs.

The United States Pharmacopoeia defines TOC and appliance as two of the four capital affection attributes authentic for PW and WFI.11 It is accessible to validate on-line assay accoutrement like the ANATEL PAT700 to be absolutely adjustable with both of these basic affection attributes, and according to the pharmacopoeial requirements.

The FDA Action Analytical Technologies (PAT) initiative4 apprenticed the biologic industry to advance in on-line action ascendancy equipment, instead of heavily relying on final artefact affection testing. This ensures bigger in-process affection control, as able-bodied as consistent in time and money savings.

Right-first-time affection for accumulation accomplishment is the best ideal outcome. Final artefact tests on biologic accessories are destructive, so 100% accumulation testing is not an option. At the aforementioned time however, one aberration during sampling and testing may see the able accumulation adverse destruction.

In adjustment to abate these risks, ample numbers of biologic manufacturers are abutting their on-line TOC analyzers to their branch ascendancy systems. This allows abeyant TOC or appliance excursions to be detected and assembly halted, preventing potentially attenuated baptize from actuality alloyed with admired alive biologic ingredients.

Revisions to the European Pharmacopoeia (EP) affiliate on WFI now acquiesce the assembly of WFI from ultra-filtration and bifold canyon about-face assimilation (RO).12 With this in mind, TOC and appliance ecology of biologic baptize systems accept become added significant. This is due to the perceived accident of abeyant contagion break-through in the RO system, back compared to the added defended barrier afforded by a baptize still.

The 4 FDA baptize affection attributes for PW and WFI are:

Within the accepted guidance, the FDA emphasizes that the 21CFR allotment 11 cardinal is alone applicative to the abstracts historian area cyberbanking annal are stored.10 The accident of on-line instruments with a congenital in, bounded abstracts historian may charge to accommodated the abounding requirements of the 21CFR allotment 11 ruling.

Tools like the PAT700 advice to abstain this affair by enabling the bounded abstracts historian to be disabled, accordingly guaranteeing that it does not allure the abounding 21CFR allotment 11 claim as a abstracts annal acclimated for cyberbanking records.

Data from on-line TOC analyzers has been commonly captivated in authentic Distributed Ascendancy Systems (DCS) or Supervisory Ascendancy And Abstracts Acquisition (SCADA) systems. This not alone offers action ascendancy improvements, but it additionally adds a abundant bulk of change control.

Contemporary approaches abundance quality-critical abstracts annal in their own defended archive, acceptance SCADA and DCS systems to be added agile, and committed alone to action control.

To abutment this, it is accessible configure the PAT700 to automatically accelerate PDF cyberbanking annal for analysis and accumulation release, transmitting these via defended FTP over Ethernet. This action meets the ALCOA requirements for cyberbanking annal to be legible, contemporaneous, aboriginal and attributable.

While class baptize affection testing chart uses reagents, necessitating chiral agreement for anniversary sample forth with approved (often daily) calibration, the on-line PAT700 does not ache from this issue, acute no reagents and alms automatic assay protocols. Additionally, the accessories alone needs to be calibrated annually.

Calibration and Arrangement Suitability Testing SOPs are wholly automated, acceptation there is no charge for chiral abstracts entry. Additionally, pass/fail letters are automatically generated, removing the charge for chiral calculations.

While GMP dictates the air affection altitude for cleanrooms acclimated in biopharmaceutical production, the absolute accident comes from the bacilli present on the animal body. Animal beings afford about 30,000 bark beef every hour,5 and all of these are potentially carriers of microbes. The technology does not yet abide to ascertain aerial bacilli in real-time, so air atom counters are currently acclimated as a substitute.

Discussions with Ecology Ecology Managers at accessories common highlight an accretion trend whereby the albatross for ecology ecology is actuality confused from QC microbiology teams to assembly staff.

This is occurring for two capital reasons: Firstly, microbiology agents are analogously big-ticket to apply in accustomed out such accepted roles and secondly, it agency beneath bodies central the cleanrooms themselves, abbreviation any abeyant for artefact contamination. Challenges appear however, because the assembly aggregation do not accept the aforementioned adeptness of accepted ecology monitoring.

In bigger biopharmaceutical accomplishment plants, teams of 10 or added technicians are amenable for bags of accepted ecology ecology samples every month. At anniversary sampling location, technicians charge manually blazon the area name into the adverse afore sampling begins.

Furthermore, counters should be manually configured in band with accounting SOPs. At the end of every day, the adamantine archetype book outs from anniversary sample area are photocopied – this is because the printers in the atom counters are thermal, so these print-outs will achromatize over time. Finally, after-effects from every area charge be manually and alone adapted into an cyberbanking format.

Manually configure counter:

Some manufacturers accept optimized their atom counting chart accurately for biologic QC use, as allotment of their efforts to advance abstracts integrity. This has included architecture in the adequacy for preconfigured cyberbanking SOPs into the apparatus architecture itself, enabling the bearing of 21CFR allotment 11 cyberbanking annal anon from the instrument.

To accomplish this, the user selects the preconfigured cyberbanking SOP afore acute the ‘Start’ button. This prompts the apparatus to accurately configure itself according to the SOP, afore accustomed out the adapted test. Finally, an cyberbanking assay aftereffect almanac is automatically produced.

As able-bodied as acceptable abstracts integrity, this automatic access has the abeyant to abate costs as there is no claim for technicians to actualize adamantine archetype annal and manually alteration this abstracts into an cyberbanking format.

Deskilling the use of air atom counters via automatic SOPs allows the albatross for cleanroom accepted ecology ecology to be confused from able microbiologists to assembly staff, abbreviation costs alike further.

MET ONE 3400 Environmental Monitoring Air Atom Counting

Cell analysis products, decidedly constant corpuscle populations, are commonly abundant for action and absorption based on the cells’ adeptness to exclude a supravital dye, such as Trypan Blue. This is about able manually via the use of a microscope and haemocytometer, but this adjustment can be both decumbent to errors and laborious.

Initially advised for quantifying claret cells, the sample aggregate acclimated in the haemocytometer adjustment is about alone 100 nanolitres. Alike accessory errors appliance this adjustment which are acquired during sample dilution, pipetting, bond or beheld archive by the technician, may aftereffect in abundant errors in results. This is because the final calculation aftereffect is scaled up to address corpuscle absorption in applicable counts/mL.

One abstraction undertaken of a aggregation of 16 experienced, abreast technicians appliance the haemocytometer adjustment showed variances in appear corpuscle absorption after-effects of up to /-20% amid members.4

The USP affiliate <1046>9 suggests that automatic corpuscle counting and action instruments may action a college amount of accurateness alongside a added reproducible enumeration. These improvements are ideal if the sample alertness date is automated, abbreviation any abeyant opportunities for artisan errors.

Results are added acceptable to be reproducible and authentic area the automatic corpuscle adverse is able to advance electronic, pre-programmed cell-counting SOP libraries that bout the manual, user-designed SOPs for corpuscle counting.

Not alone does this access advance accurateness and reproducibility, automatic corpuscle counters may lower the amount of this QC assay by enabling technicians to undertake added tasks while cat-and-mouse for the adverse to automatically complete the alertness and counting stages for anniversary sample.

Counters which are able of counting from 96-well plates additionally action cogent accumulation in agreement of artisan time, which after-effects in a abridgement of QC costs.

Automating the corpuscle counting SOPs after-effects in the adjustment actuality added robust, breeding the cyberbanking almanac contemporaneously, arch to bigger abstracts integrity. Because of this, the after-effects are attributable, legible, contemporaneously created, aboriginal and accurate, as per the FDA ALCOA advice in the 21CFR allotment 11 advice document.6

Though about harmonized, requirements for parenteral biologic chapped testing are occasionally assorted amid altered countries and altered products.

The sample aggregate to be analyzed and the after-effects advertisement architecture may alter appreciably amid products. For example, sampling requirements for baby aggregate ameliorative protein accessories like vaccines7 are acceptable to be altered to sampling requirements for a ample aggregate parenteral like an intravenous dribble bag.8

It is important that after-effects are affected and bidding in an adapted architecture for the artefact beneath test, for archetype counts per alembic or counts per mL.

While general-purpose aqueous atom counting accessories may be acceptable for the testing of particles in parenteral products, counters which are optimized for the specific appliance are a bigger option, primarily due to the capricious degrees of complication complex in the testing.

Particle counters which are appropriately optimized for this testing absorb assorted compendial tests, actuality able to account a pass/fail aftereffect automatically. Because QC teams will about use a artefact cast name to assuming the artefact sample beneath test, optimized atom counters artlessly absorb the user selecting the all-important assay for anniversary sample by allotment the adapted artefact by name from a drop-down menu.

While the industry focuses on omissions and errors in 21CFR allotment 11 cyberbanking records, the axiological affair is that retraining may not be the able solution. Chiral SOPs are artlessly not able-bodied abundant to anticipate recurrences of abstracts errors and omissions in the future.

QC chart which automates the affection ascendancy SOP has the abeyant to abate the appulse of animal absurdity on abstracts candor issues while accompanying abbreviation the time that technicians charge absorb accustomed out the SOP, both consistent in important amount savings.
