Bridging Clinical and Commercial Drug Product Manufacturing – Outsourcing Advice from a CDMO

Bridging Clinical and Commercial Drug Product Manufacturing – Outsourcing Advice from a CDMO

The point in drug development where a project moves from the clinical to the commercial stage often brings unforeseen challenges that may cause delays in bringing a drug product to market. Chief among these is a lack of global capacity and infrastructure to successfully scale up sterile products to commercial levels.

Drug shortages, especially for sterile injectables, have been a pressing issue for several years.1 While pharmaceutical CDMOs have invested in additional manufacturing capacity, market estimates still predict that demand for aseptic manufacturing services will outpace supply in the next two years.2 In the rapidly expanding cell and gene therapy market, for example, manufacturing capacity shortfalls are estimated to be 5 times the current demand and will continue to grow in coming years. Drug developers report difficulty finding CDMOs with both clinical and commercial manufacturing expertise to help them get to market.3

In addition, events of the last 12 months have seen COVID-19 vaccines and treatments prioritized by larger pharma companies and their manufacturing partners. This has further reduced available production capacity to commercialize new therapies.

While around 80% of clinical trials were delayed or put on hold during 2020, many pharmaceutical executives estimate that clinical trial activity will return to pre-COVID levels in 2021.4,5 With all of this in mind, what can drug developers do to mitigate manufacturing capacity issues and ensure that their drug programs are given the priority they deserve?

Scale-Up Challenges for Sterile Drug Products

There are several reasons why manufacturing capacity is limited at the clinical-to-commercial stage.

Lack of Infrastructure and Expertise

Companies looking to commercialize a sterile drug product need access to manufacturing infrastructure and a team capable of scaling up from small clinical batches to commercial production. Meeting key deadlines and going to market depends heavily on this team’s ability to troubleshoot and adapt to processing challenges. However, many drug developers do not have this capability in-house.

Small start-up or virtual companies often rely on partners for their manufacturing needs. While they may find a contract development and manufacturing organization (CDMO) that can manufacture commercial scale can be challenging or impossible if the partner is not equipped for registration batches and beyond.

While transitioning to a separate CDMO for commercial production is possible, it can delay a project with additional qualification and training activities. Ideally, smaller companies can simplify the process by putting their lead candidate in the hands of a single partner that understands the needs of both clinical and commercial supply.

Larger companies, meanwhile, may not have the flexibility or available capacity to ramp up production for new drug products. Cleanroom space is often dedicated to existing, marketed products, and production lines may not be equipped for low-volume products, such as orphan drugs.

In cases like these, a CMO with flexible cleanroom space and the ability to work with a range of batch sizes plays a critical role in commercialization.

Supply Chain Obstacles

The prioritization of COVID-19 vaccines has further reduced manufacturing capacity at the clinical-to-commercial stage for new drug products. In addition to decreased capacity, the pandemic has also restricted the availability of supplies of vital components and resources, such as vials and other packaging, as well as intermediates and raw materials.

This is a universal issue across all of pharma, and it requires manufacturing organizations to maintain robust supply chains and plan ahead to mitigate risk.

Overcoming the Hurdles

Given these potential challenges, it is no surprise that drug developers – both large multinationals and smaller virtual businesses – may feel daunted by the prospect of bringing a treatment to market in the current climate.

In times like these, it’s more important than ever to partner with CDMOs that are transparent, attentive, and able to adapt to your project needs. These expert partners have the experience, resources, and capacity, as well as the reliable supply chain, to prioritize your project and bring it from clinical to commercial.

To find the right partner with the right capabilities for your needs, it’s important to ask them a few key questions:

  • Do you have the availability and capacity to work on my project straight away?
  • How have you secured your supply of raw materials against potential shortages?
  • Will my project be a priority for your team?
  • Do you have a minimum batch size?
  • Does your site have the flexibility to increase production volumes as my project progresses?
