Trials Tracker

Due to COVID-19 some cystic fibrosis (CF) clinical trials may be suspended with new trials postponed. Please see the relevant advice on the COVID-19 Q&A page. The Trials Tracker brings together all CF trials currently recruiting in the UK, so you can find clinical trials you can take part in both in your region and further afield. We are constantly updating and developing the functionality of the Trials Tracker – please help us by completing the online poll or contact us at clinicaltrials@cysticfibrosis.org.uk.

A Study looking at the long-term use of a CFTR modulator combination therapy (VX-445)

This study will evaluate the long-term safety and tolerability of VX-445 in triple combination withT ezacaftor (TEZ) and Ivacaftor (IVA) in subjects with cystic fibrosis who are homozygous or heterozygous for the F508del mutation..

    Restore CFTR Function

A study of the combined effects of three CFTR modulator medicines in children with cystic fibrosis aged 6 to 11 (VX18-445-106)

VX-445 is an investigational medicine being studied to see how well it works and how safe it is in children with cystic fibrosis aged 6 to 11 years, when taken in combination with tezacaftor and ivacaftor. All three medicines are CFTR modulators which means that they help the faulty CFTR protein found in cystic fibrosis to work properly. Tezacaftor is already approved for use and is what is known as a ‘corrector’. Ivacaftor is also already approved for use and is what is known as a ‘potentiator’. VX-445 is a corrector. Trial participants will be asked to take VX-445, tezacaftor and ivacaftor in the morning (2 tablets), and ivacaftor in the evening (1 tablet). Everyone in the study will receive all three of the study medications, no placebo is involved. This study is divided into two parts. Part A will recruit 12 people who will be asked to come into clinic around 6 times over 10 weeks. Part B will recruit 56 people who will be asked to come into clinic around 11 times over 32 weeks. During visits, the effect of the treatment on your CF will be measured with sample collection, lung function, questionnaires, and other medical checks.

    Restore CFTR Function

Study Designed to Assess the Safety, Tolerability and PK of PTI-808 in Adults With Cystic Fibrosis

In this study, the investigational CFTR modulator medicine PTI-808 will be given in combination with one or two other investigational modulator medicines, PTI-801 and PTI-428. PTI-428, PTI-801, and PTI-808 are considered cystic fibrosis transmembrane conductance regulator (CFTR) modulators being developed to treat the underlying cause of cystic fibrosis. PTI-428 is a CFTR amplifier that increases the amount of CFTR protein in the cell, PTI-801 is a CFTR corrector that improves the processing of CFTR protein in the cell, and PTI-808 is a CFTR potentiator to enhance the activity of CFTR at the cell surface. Modulators on their own have been shown to have limited activity, and it is predicted that combining modulators will be necessary to address CFTR defects. There is a screening visit up to 4 weeks before the active portion of the study, which lasts 4 weeks. In the active portion of the study, participants will take one of the following: PTI-808 by mouth in combination with PTI-801 and PTI-428, PTI-808 in combination with PTI-801 and placebo, or all placebos for 4 weeks. The study medication is taken once a day at breakfast. Two weeks after stopping the study medication, another visit will occur.

    Restore CFTR Function

A study to learn more about a combination of CFTR modulator medicines in people with Cystic Fibrosis (VX 18 445 104)

This study is being done to learn more about a new medication called ‘VX-445’ when taken in combination with tezacaftor and ivacaftor. All three of these medications are known as CFTR modulators. CFTR modulators work to treat the underlying genetic cause of cystic fibrosis. This combination of medication is being assessed in people with Cystic Fibrosis who are 12 years and older and who are heterozygous for the F508del mutation and a gating or residual function mutation. The study will investigate how well these medications work and to check that they are safe to use. It is the hope that this combination of medications will have positive effects in some people with Cystic Fibrosis Participants will be asked to come into the clinic at the recruitment centre 9 times over a 5 month period where a study assessment will take place (blood tests, questionnaires, lung function etc.).

    Restore CFTR Function

A study of the combined effects of three CFTR modulator medicines in people with cystic fibrosis aged 12 and older (VX18 445 113)

In order to take part in this study you will already be taking part in the VX17-659-105 study, taking VX-659 with tezacaftor and ivacaftor. For this new study, you will switch to taking VX-445 instead of VX-659. Both combinations work in the same way. VX-445 is a medicine being studied for how well it works and how safe it is in people with cystic fibrosis. Your participation in this study will help us learn more about the long-term safety of VX-445 in combination with tezacaftor and ivacaftor. All three are CFTR modulators which means that they help the faulty CFTR protein to work properly. Tezacaftor is already approved for use and is what is known as a ‘corrector’. Ivacaftor is also already approved for use and is what is known as a ‘potentiator’. VX-445 is a corrector. Everyone in the study will get the study medications.If you meet the criteria for being in the study, you will take VX-445, tezacaftor and ivacaftor in the morning (in 2 tablets), and ivacaftor in the evening (1 tablet). You will be asked to come into clinic around 12 times over the 22-month (nearly 2 years) participation period. During visits, the effect of the treatment will be measured with sample collection, lung function, ECG and other medical checks.You will also receive 14 telephone calls during the participation period, each lasting around half an hour. You do not have to come to clinics for these calls.
