Скачать или смотреть EP 124: Pioneering gene therapies for PCD with John Matthews from ReCode | The Genetics Podcast

Summary:

On Rare Disease Day, we’re joined by John Matthews, Chief Medical Officer at ReCode Therapeutics. John and Patrick discuss how ReCode is using lipid nanoparticle technologies to revolutionise delivery of novel mRNA and gene correction therapies to Primary Ciliary Dyskinesia (PCD) and cystic fibrosis patients.

Listen in to find out how ReCode and Sano are collaborating to offer eligible patients free genetic testing to better understand the mechanisms behind DNAI1-related PCD, and much more.

Show Notes:

0:00 Introduction

01:10 How growing up in Malawi planted the seeds for John’s career in medicine and transition to therapeutic development

04:35 Why John focuses on rare diseases and conditions such as asthma

06:01 What has changed over the last decade in terms of treating and understanding asthma and the progress that genetics has enabled

07:31 What drew John to ReCode and the areas and projects the company is working on

09:20 How clinical loss of function in ciliary cells provides insights into the genetic causes of Primary Ciliary Dyskinesia (PCD) and drives development of relevant therapeutics

11:15 New frontiers: Restoring ciliary cells in subsets of cystic fibrosis and PCD caused by loss of genetic function

13:05 ReCode’s delivery platform: How the company is pioneering tissue specific delivery with lipid nanoparticles.

19:01 Situs inversus: Prevalence and PCD

20:33 What is currently known about PCD penetrance and inheritance patterns

21:25 Challenges and complexities of drug development in common vs. rare diseases

24:37 Key differences in running clinical trials: rare vs. common therapeutic areas

27:15 How rare disease-focused companies are using natural history data to reduce the need for placebos at clinical trial

30:52 The Liver Forum: the movement to pool natural history data across major clinical trials to provide large, high datasets

33:26 How innovative programmes in the UK are aiming to securely and ethically share data at scale

35:35 Looking to the future: How innovation lies in the ability to use genetics and secure data sharing as a guiding principle for rapidly developing and delivering new treatments

37:21 The importance of data sharing to enable preventative measures

37:43 The transformative power of registries and patient-owned data
