A real urgency
An analysis by Porsche Consulting clearly shows that of 1,000 molecules considered promising candidates for new medications, only around half of them survive the first phase of clinical studies. All the others are rejected, usually because of major side effects. In the second phase, which tests the dosage and efficiency of active substances, the cohort loses around another three-quarters of its members. And in the third phase, with trials on thousands of people, another 40 percent of the candidates do not pass muster. Ultimately only around ten of the initial 1,000 agents will make it through the approval process, ready for use as therapies. This often takes a decade or more, and can devour billions of euros.
These figures are not specific to biopharmaceuticals, but also reflect development challenges faced by drug companies that make medications based on chemical molecules. But they indicate the magnitude of development costs in the sector. How can the processes become cheaper and faster? One possibility is to make greater use of artificial intelligence (AI). An analysis from the journal Drug Discovery Today has shown that 80 to 90 percent of candidates selected by AI make it through the first phase of clinical studies. That is an enormous increase over the number selected “manually” by research personnel. Targeted investments in AI therefore make sense for pharmaceutical companies. Another possibility lies in the phase before human trials and consists of replacing the obligatory, albeit error-prone, tests on animals with organ-on-a-chip experiments. For this, human cells are cultivated in a lab to make small amounts of tissue suitable for drug tests — an approach that will depend on favorable regulatory frameworks in the future.
It is also important to entrust the development of new medications to diverse teams. Not only R&D specialists should be involved right from the start but also representatives from manufacturing, marketing, regulatory affairs, and quality management. The combined perspective helps to save time and costs because it ensures that only the most promising candidates are admitted to clinical studies in the first place.
Looking at this from a global perspective, there is potential for speeding up the pace of these processes. International companies often reach phase 3 or beyond in advanced biologics, while German players are still in phase 1 or 2.
That being said, German companies can learn from other companies’ best practices — particularly of U.S.-based enterprises — and quickly catch up. For this, they need to place a higher priority on innovative technologies in their R&D departments, ideally in market sectors where they are already competitive. Strategic outsourcing of individual activities can further accelerate progress.
