Astudiaeth Cyfnod Cynnar yn edrych ar wrthgorff i dderbynnydd ffolad a gaiff ei fynegi mewn nifer o ganserau gwahanol, sy’n gysylltiedig â chyffur a all ladd celloedd canser.

Noddwr: Eisai Ltd

Math o ganser: Canser y fron Triphlyg Negyddol, canser yr endometriwm, canser yr ysgyfaint o fath celloedd mwy a chanserau’r ofari.

Mae MORAb-202 yn gyffur arbrofol sy’n gweithio trwy dargedu ac ymlynu wrth gelloedd tiwmor canser sydd â phrotein penodol o’r enw derbynnydd ffolad alffa ar wyneb y gell. Mae’r protein hwn i’w gael fel arfer o fewn canser y fron triphlyg negatif, canser yr endometriwm, canser yr ysgyfaint o fath celloedd mwy a chanser yr ofari.

Unwaith y bydd MORAb-202 yn mynd i mewn i’r celloedd tiwmor mae’n rhyddhau cyfansoddyn o’r enw Eribulin, sy’n gweithio trwy ladd ac atal celloedd canser rhag lluosogi.

Mae tair rhan i’r astudiaeth hon.

  • Cynyddu’r Dos – i bennu a nodi’r dos diogel uchaf y gellir ei oddef o’r cyffur dan sylw, sef MORAb-202.
  • Cadarnhau’r Dos – i gasglu mwy o wybodaeth am ddiogelwch ac effeithiolrwydd dosau dethol o’r cyffur dan sylw mewn cyfranogwyr â chanser endometriaidd a chanser yr ofari.
  • Optimeiddio’r Dos – casglu mwy o wybodaeth am ddiogelwch ac effeithiolrwydd MORAb-202 gan ddefnyddio gwahanol ddosau ac amserlenni gweinyddu ac i gasglu gwybodaeth ynghylch a all cwrs byr (3 diwrnod) o corticosteroidau (cyffuriau fel prednisone/prednisolone neu dexamethasone a all leihau llid) leihau’r siawns o ddatblygu clefyd interstitaidd yr ysgyfaint (llid yr ysgyfaint) sydd wedi’i nodi ar ôl triniaeth gyda MORAb202.

“So far the trial has been looking at increasing doses of the compound to test it is safe and looking for early signs of activity. This part of the trial has completed, and data is being analysed.

The next step will be to enrol more patients at a defined dose to get further information on activity.”

Professor Robert Jones, Principal Investigator for the MORab-202 trial at Velindre Cancer Service and Early Phase Cancer Trials Lead in Wales

“MORAb-202 was the first CCRH trial to open and recruit patients. We are able to seamlessly deliver treatment in the University Hospital of Wales whilst maintaining all other visits in Velindre Cancer Centre.

As a dynamic nursing team, we provide continuity of care by seeing patients in both sites and being a familiar face during novel treatment. We collaborate with clinical fellows, consultants and other multi-disciplinary colleagues to ensure safe practice for patients on clinical trials.“

Agustina Spooner was the first patient on this clinical trial with the Cardiff Cancer Research Hub. She talks about her experience and explains why she agreed to take part in the trial.
