Foreign particles – Regulatory pressure increases
FDA: “As an agency, we want to know that you understand what product you’remaking, so that you know what is or isn‘t acceptable… There are risk-based,science-based decisions that you need to make as the manufacturer of the final drugabout what you can tolerate in your incoming raw materials, including the excipients.So if you have particles, we would like to see that you understand what they are. Perhaps it‘s as simple having a discussion with your supplier and being able to explain to the agency what the particles are and why they are not a risk to public safety or patient safety, which is our prime concern. Risk management, good science, andalways keeping the safety of the patient in mind is what we‘re looking for.” Source: Atypical Visible Particles, industry roundtable, IPEC, Jul 2, 2012 – Pharmaceutical Technology, Volume 36, Issue 7, pp. 86-88

APIC and IPEC determine the current discussion
APIC
Currently the guidance from health authorities (EMA, FDA, others) or Pharmacopoeias (e.g. EP, USP) about particles in APIs is very limited
This lack of guidance has led to uncertainty of how to deal with insoluble matter, and has sometimes resulted in the unrealistic expectation that no single visible particle should be present in any amount of API, irrespective of its size or the overall amount present in a batch
Therefore the idea was born to develop such a guidance document as a basis for common understanding regarding the presence of particles in APIs

Observation of visible particlesnormally triggers investigation requiring extensive time, money and resources to be expended in identifying the source of the particles
The visible particles … pose minimal risk to patient safety
With current technologies, these particles are technically unavoidable and cannot be reduced to a lesser amount in the finished product
This guide encourages communication between excipient makers and users to reduce time, money and resources expended and to ensure adequate investigation

Benefits to the industry and to Health Authorities
BenefitIPEC Federation Guide
Provides a basis for a common understanding regarding the presence of visible particles
1A central cause of the increased concern is the issuance of several US FDA Form 483s to pharmaceutical companies by FDA investigators for insufficient or incomplete investigations of unusual, visible particles. These 483s did not prohibit these technically unavoidable particles, but addressed the insufficiency of the investigation process.
2IPEC’s TUPP guide provides a pathway to provide data on the identity and origin of these particles in excipients as a way of fulfilling the investigational component of the identification of unusual visible particles in excipients.
3The TUPP guide encourages communication between excipient producers and users to reduce time, money and resources expended and to ensure adequate investigation.

Presence of technically unavoidable, inherent particles in excipients is acknowledged by users,
but users request that suppliers…
support identification and characterization of the foreign particles
perform a root cause analysis on source of particles
master contamination (CAPA taken) to maintain the TUPs at an acceptable level

Testing of products according to internal monographs or against current Pharmacopeia is sometimes not sufficient to detect particles.
We routinely perform:
visual control of solids for particulate matter on lab samples of bulk material produced
appearance of solution test on labs samples (typically 10 g in 100 mL)
test for insoluble matter by filtration / weighing
All tests suffer from
low contamination level of foreign particles
inhomogeneity of distribution of foreign particles
QC control strategies

Limits on specification?
Specifications or limits for TUPs cannot be expected on CoAs: The insignificant number of particles
relative to batch size and the intermittent nature of their observance make a specification unrealistic
and unreliable
Information and QC-methods on “typical” amounts of TUPs may be item for discussion between user
and supplier
Excursions above these “typical” limits cannot always be prevented as the low levels and low
detectability may be beyond the capability of the process

Concept behind TUPPValue added for Customer and Supplier
29
Establishes understanding of chemical manufacturing and its
limitations at customers side
Enables customers to perform a quick and reliable risk-
assessment for direct materials and final products
Helps to differentiate between complaints and typical
properties of a substance
Avoids unnecessary actions and crisis management
Finally will (might) reduce the number of complaints
