A strict expiry date for the product was specified by the client, and the challenge was greater than usual as the order was placed during the Christmas period, which meant warehouse closures and delayed response times from suppliers. To make matters more complex, the client requested a change in quantities after the initial order, resulting in split deliveries that risked further extending the timescale. Solution Despite these obstacles, CSI successfully leveraged its relationship with a local vendor to secure the required quantity of the specified ophthalmology medication. Effective communication and coordination between CSI, the client, the vendor and CSI’s warehouse were key during the disrupted holiday period and ensured smooth delivery and completion of quality control checks. Result The required quantity of aflibercept was successfully delivered to CSI’s warehouse for immediate distribution to hospitals. True to our promise that no patient would be turned away for lack of medication, the ophthalmology product was delivered within the specified timeframe to several hospitals in the United States.

Biopharmaceuticals have seen significant advances in recent years, particularly with the development of biologics and biosimilars. These innovative therapies have revolutionised the treatment landscape and have become the new standard of care for various conditions such as cancer, auto-immune disorders and genetic diseases, offering enhanced efficacy and reduced side-effects in comparison to traditional small molecule drugs. A biosimilar is a type of biologic medicine that has been developed to be highly similar and clinically equivalent to an existing approved biologic (referred to as a ‘reference medicine’ or ‘originator medicine’) in terms of structure, biological activity, immunogenicity, quality, safety and efficacy. They are in great demand and are quickly becoming the standard of care in clinical trials due to their safety, efficacy and competitive pricing. Latest information can be found on the European Medicines Agency (EMA) website. As with any biologic medicine, details of biosimilars’ licensed indications are included in the British National Formulary (BNF). It is important to note that biosimilars are not considered generics of biologic medicines. This is due to the small degree of variability (‘microheterogeneity’) that naturally exists in the complex structure of the active substance within and between batches. To ensure the consistency and quality of all biological medicines, including biosimilars, UK and EU legislation upholds strict requirements. Learn more about key regulatory considerations on CSI’s blog Biosimilars FAQ When purchasing biosimilars for use in clinical trials, the following questions are often raised: Is the biosimilar licensed for all the indications and routes of administration required? 1 Is the biosimilar available in suitable strengths and presentations? 2 Is the administration device acceptable to the patient and are product-associated support services available? 3 CSI’s scientific knowledge and experience of supplying biologics and biosimilar medicinal products to complex global studies means we are perfectly placed to navigate these questions and help our partners to deliver successful trials.

Due to unforeseen circumstances at the warehouse, the intermediate storage of the medication became impossible at very short notice. Since the re-supply date for the medication was in less than 10 days’ time, rapid action was required to maintain timely supply for the trial. Solution While it is critical to the success of any study to ensure that Quality standards are upheld and regulations followed, there is sometimes also need to be adaptable to respond to shifting priorities in ongoing studies. As such, CSI’s Project Management team reached out to our Quality team with viable alternatives to the original warehouse. The Quality team proceeded to adjust their working hours to facilitate immediate communication with the new warehouse located on the other side of the globe. Result Having successfully gathered all documentation required, and after performing a full audit and qualification of the warehouse in just 5 days, the efforts of CSI’s Quality team ensured consistent supply of the product required for our partner’s clinical trial that was in progress and could not afford to be delayed. This was an excellent display of efficiency and collaboration between CSI and the new warehouse’s Quality teams.

The product in question was scarce on the market at the time and the client had recently been let down by a competitor, so supply timelines were extremely tight – the first shipment was required in less than 8 weeks. To make matters more complex, a quota system had been introduced for the product in some markets, with suppliers receiving only a small quantity of the product as stock was needed to supply the local market. Solution CSI proved flexible in offering to start the work of sourcing and purchasing the product following receipt of email confirmation of the award of the study – before the client had even finalised the full scope of work and raised a purchase order – in order to condense timelines. We were then able to leverage our European supplier contacts to source the product very quickly and, within six days of the client’s original request, CSI had formed a comprehensive proposal for the client, including all costs for sourcing and distribution. Result The Biotech was able to proceed with their oncology study in Europe without delay to its timelines. CSI received glowing feedback from the client for its work in supporting this trial and has since been awarded further business from them.
