In January, we informed you of SafeBridge’s transformation to SafeBridge® Regulatory and Life Sciences Group. This newer and larger group still has the same roots and core competencies, but has expanded into specialty chemicals including food and beverage ingredients, biocides, and other specialty chemicals.

What does this mean for you, our Clients?

  • A broader experienced staff of toxicologists (now 22) to serve many industries including pharma, biotech, food and beverage ingredients, biocides, and specialty chemicals;
  • Additional support in regulatory compliance including worldwide submissions to agencies including ECHA, FDA, EMA, MHRA, and various regulators in Asia;
  • GLP compliance auditing for studies including genetic and mammalian toxicology, environmental fate and effects, and physico-chemical property studies for submission to regulatory agencies;
  • Greater potential for “turn-key” projects –we can now handle these projects starting with determining the proper protocols, finding laboratories to do the testing, to submitting the results to the regulatory authority;
  • Safety Data Sheets (SDSs) and Poison Control Notification (PCN) dossier preparation to meet business needs and regulatory requirements;
  • An industrial hygiene staff of “potent compound safety” as well as general industry experts; and
  • An AIHA accredited lab with expanded capabilities to meet compounding pharmacy requirements.

Why are we calling this Phase 2?

Phase 2 means we are integrating our services to find the appropriate subject matter experts resourced to meet your needs. As we have always said: “Give us your most difficult occupational or product safety issue, and we can help provide the robust and scientific expertise to address the challenge”.

Phase 2 also means integrating the SafeBridge entities with other parts of our parent company Trinity Consultants Inc., so we can provide a full spectrum of services for our clients. Our affiliated companies include Working Buildings and Advent Engineering who provide GMP auditing, facility and process design, and qualification for the life science industries including biotech and pharma companies.

Biologically Derived Therapies

The past ten to fifteen years have seen an exponential growth in the development of new drug therapies that are derived from biological sources. These therapies provide many safety advantages over traditional “small molecules” that are synthesized by chemical reactions. Just as health and safety professionals are asked to evaluate and control small molecules, these biologicals also require hazard evaluation and exposure control. However, the tools we use to evaluate and control these hazards can be significantly different for those we have traditionally used for small molecules.

In order to advance the knowledge of health and safety professionals in the industry, SafeBridge recently developed and presented a webinar entitled “Biologically Derived Therapies: Evaluating Their Hazards and Controlling Their Exposures”. In this webinar, we defined the types of therapies that would be considered biologicals to include vaccines, components of blood, proteins, cytokines, monoclonal antibodies, and oligonucleotides. It does NOT include “biological agents” which are defined as any pathogenic or living organism, such as viruses, bacteria, human or other animal cells.

The initial inclination when trying to perform a qualitative hazard assessment of these biologicals is to use the criteria matrices we have been using successfully for small molecules. However, the data collected on these molecules can be slightly different that those available for small molecules. The user may be at a loss for how to use this criteria matrix. To address this, SafeBridge has proposed a different criteria matrix to be used when categorizing biologicals.

Containment and control of biologicals to protect workers can also be very different due to the different types of operations used to develop and formulate these drugs. These operations include fermentation, column chromatography, filtration, and harvesting. SafeBridge recommends reviewing the process flow diagram and isolating the various steps where exposures may occur. Most of the “upstream” steps to synthesize the drug involve true biological agents such as mammalian or bacterial cells, while most of the “downstream” steps deal only with biologicals. Many of these operations involve liquids under pressure which means that leaks can generate aerosols and can contaminate the workplace and workers. Even though many safety professionals will be relieved that the drugs are in a liquid form, the pressurization of that liquid can cause some concern.

The process we undergo to evaluate hazards of biologicals and control their exposures is similar to what we use for small molecules. We just need to adapt the tools we use to this new paradigm.

The webinar is available on-line through our Vimeo account and can be rented for additional viewing.

Nitrosamine Update

In 2018, nitrosamine impurities, including N-nitrosodimethylamine (NDMA), were found in a number of angiontensin II receptor blockers, which are blood pressure medicines known as "sartans.” Nitrosamines are chemical compounds highly reactive chemical compounds, which may be formed during synthesis of a drug substance or a drug product, or through degradation of drug products. They are highly reactive compounds that are probable human carcinogens, on the basis of animal studies, with a high potency. This finding initially led to voluntary product recalls. However, nitrosamine impurities were subsequently detected in batches of ranitidine, an over-counter (OTC) medicine used to treat heartburn and stomach ulcers, as well as metformin, a diabetes drug; other product recalls were instituted as a result.

Nitrosamines, as a class, are now recognized as a “Cohort of Concern”, signifying that the lowest recommended limit of 1.5 µg/day for DNA-reactive impurities (see ICH Guideline M7(R1)) may not be sufficient. A number of regulatory agencies, including the US Food & Drug Administration (FDA) and the European Medicines Agency (EMA), have established interim intake limits for 6-8 specific nitrosamines, ranging from 26.5 to 96 ng/day for the patient population, and strict new manufacturing requirements have been implemented by these agencies. The interim limit for nitrosamines of unknown toxicity/potency is even lower.

The EMA Committee for Medical Products for Human Use (CHMP) now requires a robust evaluation of the potential risk of nitrosamine formation in approved products containing chemically synthesized APIs, including generics and OTC products for existing/marketed drugs and new authorization applications. The risk assessment should be conducted following the approach outlined in the ICH M7 guidelines and documented using prescribed templates. If a potential risk is identified, the appropriate risk-mitigating measures, including analytical verification of the absence of nitrosamines may be needed. If nitrosamines (or a risk of their potential formation) are detected, this must be communicated to the EMA. Additionally, risk evaluation is now required in new authorization applications.

Risk evaluation documents for existing products do not need to be submitted to EMA but should be made available upon request. Companies should inform competent authorities if a nitrosamine is present in a product, irrespective of the amount detected. This may require manufacturing process changes and it is suggested that companies liaise with competent authorities in these situations.

It is important to recognize that, while nitrosamines as a class are considered a Cohort of Concern, not all nitrosamines are highly reactive or potentially carcinogenic. For each compound identified, a robust health hazard assessment must be implemented to establish appropriate limits, whether they be in ng-range of higher.

Does your company have adequate systems in place to identify and evaluate the risk of potential nitrosamine formation, and to take appropriate steps in the event of an identified risk?

SafeBridge Regulatory & Life Sciences Group are a team of Board Certified or equivalent toxicologists with significant experience in hazard assessments, including ICH M7 evaluations. Together with Ph.D. chemists available to evaluate drug synthesis pathways to predict potential nitrosamine formation under various potential processing conditions, we can provide necessary expert technical advice to meet this regulatory need. Please contact Allan Ader, Ph.D., DABT, Managing Director via email for further information and assistance with nitrosamine risk assessments.
