The Cost of Biotech Innovation: Exploring Research and Development Costs of Cell and Gene Therapies.

BACKGROUND

Clinical development paradigms for cell and gene therapies appear to be different to those of more conventional treatments: therefore, it is informative to explore this from the perspective of investments required to bring a new cell and/or gene therapy to the market. While there are a number of studies in the literature analyzing clinical-stage R&D costs for novel therapeutics, these are 'modality-agnostic' and thus do not elucidate costs specifically for the emerging class of cell and gene therapies.

OBJECTIVES

The objective of this study was to understand the research and development (R&D) costs associated with the clinical development of new cell and gene therapy assets METHODS: As part of our analysis of clinical-stage R&D costs for cell and gene therapies, we focused our efforts on cell and gene therapy assets recently approved by the US Food and Drug Administration (FDA) or expected to receive FDA approval by the end of 2024. A total of 25 therapies were identified for the study, 11 of which had sufficient level of detail for our clinical-stage R&D costing study. We calculated the clinical-stage R&D costs to bring a new cell and/or gene therapy to the market following a three-step approach, starting with (1) calculation of the out-of-pocket investment reported in US SEC reports; (2) we adjusted these figures for the risk of failure by applying a clinical trial phase-dependent attrition risk rate; (3) we accounted for the cost of capital of 10.5%.

RESULTS

After accounting for R&D attrition rate (i.e., costs of failed programs) and applying a cost of capital at 10.5%, we estimate that the clinical-stage R&D investment required to bring a new cell and/or gene therapy to market is US$1943 M (95% CI US$1395 M, US$2490 M).

CONCLUSION

This knowledge can inform financial planning for biopharma companies looking to enter the space and inform policy makers within the context of the commercialization and pricing of such therapies.
