Detaljeret beskrivelse
Cystinose er en sjælden arvelig recessiv sygdom, der tilhører familien af lysosomale lagringsforstyrrelser og er karakteriseret ved lysosomal ophobning af cystin i alle kroppens celler, hvilket fører til multiorgansvigt. Cystinose har en ødelæggende indvirkning på de berørte individer, primært børn og unge voksne, selv med cysteaminbehandling. Forekomsten af cystinose er 1 ud af 100.000 til 1 ud af 200.000. Genet involveret i cystinose er genet CTNS, der koder for den transmembrane lysosomale cystintransporter - cystinosin. Den nuværende standard for pleje forhindrer ikke udviklingen af sygdommen og påvirker i væsentlig grad livskvaliteten for patienter med cystinose.
Til denne undersøgelse vil op til 6 forsøgspersoner, der opfylder berettigelseskriterierne, blive transplanteret efter et 3-kohorte forskudt behandlingsdesign med 2 forsøgspersoner pr. kohorte. De første 2 kohorter vil bestå af 4 voksne (18 år eller ældre), potentielt efterfulgt af en kohorte bestående af 2 unge eller voksne (> 14 år). Efter processen med informeret samtykke vil tilmeldte forsøgspersoner blive screenet for at bekræfte fuld berettigelse til deltagelse. Kvalificerede forsøgspersoner vil gennemgå hæmatopoietiske stamceller (HSC) mobilisering og indsamling (leukaferese). En del af cellerne vil blive opbevaret som "back-up" til redningsformål, hvis det er nødvendigt, og en del vil blive ex vivo genmodificeret med en lentiviral vektor, pCCL-CTNS eller pCDY.EFS.CTNS.T260I, for at udtrykke CTNS-genet (produktnavn: CTNS-RD-04). Klinisk fremstilling til patienter i kohorte 3 vil introducere en transduktionsforstærker LentiBOOST (produktnavnet for disse patienter vil være CTNS-RD-04-LB, hvor suffikset "-LB" står for LentiBOOST). Forsøgspersonerne vil modtage marvcytoreduktion med busulfan før infusion af CTNS-RD-04. Forsøgspersoner vil afbryde cysteaminbehandling i løbet af vurderingsperioden. Opfølgningsperioden for vurderingen vil omfatte de første 2 år med aktive slutpunktsevalueringer, hvor forsøgspersonerne vil blive evalueret 3-, 6-, 9-, 12-, 18- og 24 måneder efter transplantationen. En langtidsopfølgningsundersøgelse (LTFU) i en samlet 15-årig opfølgningsperiode vil blive tilbudt alle forsøgspersoner.
Formålet med denne fase 1/2 kliniske undersøgelse er at vurdere sikkerheden/tolerabiliteten af CTNS-RD-04 og dets effektivitet gennem en række kliniske, molekylære og biokemiske vurderinger.
