This study is a phase II study of AZD6738 in combination with durvalumab in patients with solid tumor (cohort A (N=30): GC who have failed secondary chemotherapy treatments regimen; cohort B (B=30): melanoma patients who have failed to IO). Patients will receive AZD6738 plus durvalumab combination regimen. AZD6738 will be administered at 240 mg twice daily on days 1 to 7 in Cycle 0 (lead-in period) and therafter at 240 mg BD on days 22 to 28 in a 28-day cycle. Durvalumab will be administered at 1500 mg every 4 weeks from cycle 1 day 1. Tumour evaluation using modified RECIST 1.1 will be conducted at screening (within 28 days prior to first dose) and every 8 weeks relative to the date of first dose, up to week 40, then every 12 weeks until objective disease progression (within a window of +/- 7 days of the scheduled date). Patients will continue to receive treatment with AZD6738 and durvalumab provided that the treatment is tolerable and there is evidence of clinical benefit (as judged by the investigator) and secure supply of medication. Upon confirmation of objective disease progression, or treatment disconiutation criteria are met, both durvalumab and AZD6738 must be discontinued. Patients may continue with AZD6738/durvalumab beyond objective disease progression (determined by modified RECIST 1.1) at the discretion of the investigator if they are clinically benefiting from the treatment and they do not meet any other discontinuation criteria. If either durvalumab and/or AZD6738 are deemed intolerable (as judged by the investigator) so that discontinuation of either agent is deemed in the patient's best interest despite dose interruptions, dose modification and initiation of supportive treatments, both durvalumab and AZD6738 must be discontinued and the patient withdrawn from the study. Patients are not permitted to continue either AZD6738 or durvalumab as monotherapy. There is no maximum duration of treatment with AZD6738 and durvalumab. The imaging modalities used for modified RECIST 1.1 assessment will be CT or MRI scans of chest,abdomen and pelvis. modified RECIST 1.1 scans will be analysed by the investigator on site. Patients will also be requested to provide tumour samples from the primary or metastatic tumours pre-study and on progression. Sample provision is mandatory, subject to aspecific consent, and will aid understanding of resistance mechanisms. However, if biopsy site is not feasible, the protocol will allow waiving the rebiopsy procedure.

Study Type
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies. |

Trial ID:
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries. |
NCT03780608 |
Phase
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use. |
