Main study: This is an open-label, phase 2 study that aims to evaluate the efficacy and safety/tolerability of ceralasertib, when administered as monotherapy and in combination with durvalumab in participants with unresectable or advanced melanoma and primary or secondary resistance to PD-(L)1 inhibition.

Official Title

A Randomised, Open-Label, Phase 2 Study of Ceralasertib Monotherapy and Ceralasertib Plus Durvalumab in Patients With Unresectable or Advanced Melanoma and Primary or Secondary Resistance to PD-(L)1 Inhibition


Biopsy sub-study: This is an open-label, non-randomised, sub-study planned in participants suitable for 3 mandatory biopsies. Serial tumour biopsies are mandated in participants recruited into the sub-study and will be taken at baseline during the screening period, during treatment with ceralasertib monotherapy and during the off-treatment period of ceralasertib monotherapy.

  • Patients must not have experienced a toxicity that led to permanent discontinuation of prior checkpoint inhibitors (CPI) treatment.
  • History of another primary malignancy except for malignancy treated with curative intent with no known active disease ≥ 3 years before the first dose of study treatment
  • Uveal melanoma
  • Must not have experienced a Grade ≥ 3 immune-related AE or an immune-related neurologic or ocular AE of any grade while receiving prior immunotherapy
  • History of symptomatic congestive heart failure, unstable angina pectoris, uncontrolled cardiac arrhythmia, which is symptomatic or requires treatment (CTCAE Grade 3), symptomatic or uncontrolled atrial fibrillation despite treatment, or asymptomatic sustained ventricular tachycardia. Patients with atrial fibrillation controlled by medication or arrhythmias controlled by pacemakers may be permitted upon discussion with the study clinical lead.
