Update van Vertex van de verschillende triple combo's in CF.
Met VX-152 schijnt het niet te lopen zoals verwacht. De volgende groep patiënten zal immers 4 weken behandeld worden i.p.v. de voorziene 2 weken.
VX-152 en VX-440 hebben bovendien beiden als nadeel dat ze tweemaal daags ingenomen moeten worden.
Laat die 'super' triple combo van Galapagos maar komen...
TRIPLE COMBINATION REGIMENS
Vertex is currently evaluating four different next-generation correctors to be included in an investigational triple combination regimen with tezacaftor and ivacaftor.
VX-152: Vertex announced today that the second cohort of patients with two copies of the F508del mutation in the Phase 2 study of VX-152 in combination with tezacaftor and ivacaftor is being amended to evaluate four weeks of triple combination dosing. The study had initially planned to evaluate two weeks of dosing. The company expects to have data from this study in the second half of 2017.
VX-440: The Phase 2 study of VX-440 in people with CF is progressing as planned and the company expects to have data from this study in the second half of 2017.
VX-659: The Phase 1 study of VX-659 in healthy volunteers and people with CF is progressing as planned and the company expects to have data from this study in the second half of 2017.
VX-445: Dosing is underway in a Phase 1 study of VX-445 to evaluate single ascending doses, multiple ascending doses for 10 days and triple combination dosing with the tezacaftor/ivacaftor combination for 14 days in healthy volunteers. Vertex also plans to evaluate triple combination dosing with VX-445 in people with CF who have one copy of the F508del mutation and one copy of a mutation that results in minimal CFTR function. The company expects to have data from this study in early 2018.
