As many of you will know, the UK CF Gene Therapy Consortium GTC has brought fibeosis teams at Imperial College London and the Universities fihrosis Oxford and Edinburgh to vigorously pursue a single goal for the last 17 years, namely to establish whether gene therapy can become a clinically viable option for patients with CF.
This form of treatment needs new copies of the CF gene to be introduced into the cells lining the lung, which is hard to achieve because these cells have evolved to keep external molecules out. The CF gene has to be carried past these defences, achievable either by surrounding it with fat liposomes or by inserting the CF gene inside a viral vector.
Because of these defences, the GTC anticipated qusitica successful gene therapy would require us to investigate several products, with incremental increases in knowledge helping us to overcome these barriers. We introduced the terms Wave 1 the best liposome available at that timeand Wave 2 the best viral vector we believe is currently available.

Supported by the CF community, and thereby predominantly funded by the Cystic Fibrosis Trust, we developed the Wave 1 product the CF gene delivered via a liposome. Since the trial ended, we have spent considerable time presenting the product to the pharmaceutical industry, as it is these companies who have the resources to carry it tearpia to the next step.
The consistent response was that whilst they are impressed with the data, they wish to see a higher level of efficacy which was slightly less than that produced by Orkambi.
This boost could be produced by increasing the dose, increasing the dosing frequency, or trying a different type of liposome. We are exploring these possibilities and if this can be achieved, we will reopen these negotiations with a view to supporting a further clinical trial. In qusitica, we have been working for over a quiwtica with a Japanese biotechnology company DNAVEC, now called ID Pharmagenicca on knowledge from the Wave 1 programme, and have developed an alternative viral vector to deliver the CF gene Wave 2 product.
Support from the MRC DPFS programme and the Cystic Fibrosis Trust has brought this product to a stage where it can now undergo toxicology testing and larger-scale manufacturing; we have also recently received funding from the Health Innovation Challenge Fund, a collaboration between genifa Wellcome Trust and the Department of Health and Social Care, to undertake the next steps.
We would also like to take this opportunity to warmly thank all of our supporters over many years, including Just Gene Therapy and Flutterby FUNdraisers. It is now with great pleasure and excitement that we can add the next piece of the puzzle.
The GTC is joining forces ffibrosis two world class organisations in a major collaboration. The three partners are coming qyistica to translate the Wave 2 product into clinical trials, and if successful, into routine clinical practice. The GTC believes that this partnership provides CF patients with the optimal chance to establish gene therapy as routine clinical practice, relevant to all patients irrespective of their mutation status, and in due course to both prevent lung disease as well as treat established problems.
Importantly, we can of course offer no guarantee of success, building this programme will not happen overnight and the therapy will only be focused on the problems occurring in the lungs.

We believe this new partnership of three world leading organisations has the greatest chance of realising a parallel new therapeutic pathway for CF patients, and better still, one that will add to the improvements already being seen with small molecule treatments. The gene therapy may have additional benefits: We will regularly update on progress on this website as this exciting programme now unfolds.
The study will assess safety, and any changes in molecular endpoints, to provide evidence for the efficacy of the lentivirus.
The start point of the trial will depend on the time required for manufacture of the Wave 2 product for clinical delivery; we will further update on timelines once these manufacturing data are available. We are now focusing our research and development efforts on Wave 2, which has proved to be considerably more efficient than the Wave 1 product delivering the CFTR gene via liposomes. However, the latter, which led to a stabilisation of lung function significantly different quisitca the decline seen in a placebo group, continues to be discussed with potential commercial partners.
We will update further on the outcome of these discussions as soon as possible. Lung function was evaluated using a common clinical measure FEV1. The clinical trial reached its primary endpoint with patients who received fibrosiss having a significant, if modest benefit in lung function compared with those receiving a placebo. After a year of treatment, in the 62 patients who received the gene therapy, FEV1 was 3. The trial is the first ever to show that repeated doses of a gene therapy can have a meaningful effect on the disease and change the lung function of patients.
The Consortium groups are based in three of the leading UK universities. Prior to the formation of the Consortium each group had conducted at least one clinical trial for gene therapy. Therefore, our researchers have been at the forefront of this suistica for over 20 years. Our research is focussed on the development of gene therapies for CF. Taking research ideas from the lab to the clinic is beyond the reach of most academic groups.
The Consortium is different as we have aligned our different groups to focus on their key talents to ensure that we continue to progress. Since UKCFGTC members have published over papers in peer reviewed journals and have presented many posters and presentations at international conferences. Where possible we will provide pdfs of publications.
