Gene Therapy for Rare Diseases: Considerations for Both Clinical
and Post-Marketing Studies

Tuesday, January 29, 2019 | 11am EST (NA) / 4pm GMT (UK) / 5pm CET (EU-Central)         

There are approximately 7,000 distinct rare diseases affecting 350 million people worldwide, approximately 80 percent of which are caused by faulty genes. Scientific advances such as the CRISPR/Cas9 genome-engineering system have simplified the pharmaceutical and biotech industry’s ability to develop gene therapies, especially for single gene mutation disorders. The US Food and Drug Administration (FDA) has more than 700 active Investigational New Drug Applications (INDs) for gene and cell therapies and in 2017, the FDA approved two cell-based gene therapies and it is anticipated that gene therapy will become a mainstay treatment for many rare diseases.

In this webinar, Quanticate and QVigilance will examine the challenges of rare diseases studies focusing on gene therapy treatments, including appropriate study design, statistical analyses and long-term post-authorisation pharmacovigilance and risk management requirements. Use of appropriate data capture and data quality oversight methods will also be discussed.

Study Design & Statistical Analyses Considerations

As most rare diseases are serious or life-threatening and have unmet medical needs, clinical research is designed to demonstrate efficacy without prolonged exposure to an ineffective treatment. To be able to design such a study, it would be ideal to have an understanding of the disease history and suitability of endpoints, but often this information is lacking. In addition, the endpoint choice for gene therapies can be further complicated by guidance asking for a demonstration of a treatment outcome that virtually never occurs in the natural course of the disease, as in the case of haemophilia gene therapies.

These items will be discussed alongside approaches for the development of a suitable clinical assessment tool for the validation of suitable biomarkers, use of historical control data and an introduction to adaptive randomisation methods.

The Pharmacovigilance Problem

At the time of authorisation of a new therapy for any rare disease indication, there is often limited safety and efficacy data because only a small number of patients have been treated with the new therapy. Furthermore, gene therapies are usually one-time procedures. Collated evidence for safety and efficacy may be limited by the short observation period of clinical trials which are unlikely to yield any effects on long-term exposure, either positive or negative.

To enhance knowledge of the known safety profile of gene therapies once the product is released on the market, pharmacovigilance and risk management of the product requires a proactive and imaginative approach to the collection of real-world data beyond the reliance on spontaneous reporting. In this webinar, the following areas will be discussed:

  • Additional monitoring schemes
  • Long-term follow-up from interventional trials
  • Targeted follow-up questionnaires and activities, non-interventional studies and registries
  • Compassionate use and other managed access programs
  • Harnessing the opportunities of patient support programs and market research
  • Risk management activities
  • Signal management

Data Capture and Data Quality Considerations

The data management of a rare disease gene therapy study should ensure all data are captured in a manner that maximises information collected whilst minimising the burden placed on often very sick patients. Following gene therapy, long-term surveillance of patients will be required, and these data must also be collected and cleaned in a controlled way. The following points will be discussed:

  • An electronic data capture (EDC) solution to ensure low monthly maintenance
  • A streamlined e-check validation approach in tandem with Data Quality Oversight techniques to reduce the burden on sites
  • Flexibility with ePRO solutions selection to ease data compliance for subjects and reduce client costs.
