About this study

The dose-escalation Part A of this study will involve patients with advanced solid malignancies refractory to standard therapy or for which no standard of care regimen currently exists. Approximately 30 evaluable patients per treatment arm (A1 or A2) will be enrolled. A3 will test viability of alternate dosing schedule for AZD5069, A4/A5 will evaluate AZD9150/AZD5069 in fixed dose combination with MEDI4736 and tremelimumab in solid tumors. there may also be safety run in cohorts enrolled (A6/A7) in specific solid tumor types (breast and prostate cancer).

Once the maximum tolerated doses (MTDs) for each of the 2 agents (AZD9150/AZD5069)in combination with MEDI4736 have been identified or the maximum doses of each of the 2 agents in combination with MEDI4736 have been reached, the dose expansion Part B of the study would commence. It will be conducted in patients with recurrent and/or metastatic (RM) squamous cell carcinoma of the head and neck (SCCHN). Between 68 and 266 eligible patients will be enrolled and will randomly assigned to 1 of the following 6 treatment arms or non randomized arm B7:

  • Treatment arm B1: AZD9150 in combination with MEDI4736 in patients with prior exposure to anti-PD-(L)1 antibodies
  • Treatment arm B2: AZD5069 in combination with MEDI4736 in patients with prior exposure to anti-PD-(L)1 antibodies
  • Treatment arm B3: AZD9150 in combination with MEDI4736 in patients with no prior exposure to anti-PD-(L)1 antibodies (2L RM SCCHN)
  • Treatment arm B4: AZD5069 in combination with MEDI4736 in patients with no prior exposure to anti-PD-(L)1 antibodies
  • Treatment arm B5: AZD9150 alone in patients with no prior exposure to anti-PD-(L)1 antibodies
  • Treatment arm B6: AZD5069 alone in patients with no prior exposure to anti-PD-(L)1 antibodies
  • Treatment arm B7: (non randomized): AZD9150 in combination with MEDI4736 in patients with no prior exposure to anti-PD-(L)1 antibodies (1L RM SCCHN)
  • Treatment arm B8: (non randomized): AZD9150 (every two weeks) in combination with MEDI4736 in patients with no prior exposure to anti-PD-(L)1 antibodies (1L RM SCCHN)

Primary outcomes

  1. Part A: Danvatirsen With Durvalumab MTDs (Maximum Tolerated Dose) or Recommended Doses for Dose-expansion

    Time frame: 35 days

    After completion of DLT period (35 days) for the maximum dose cohort. A CRM-based approach was used to identify the set of dose combinations where the incidence of DLT was ≤ 33%. The dose with expected DLT incidence closest and below 0.33 at this point was the "model estimated" MTD. During trial execution, the Safety Review Committee (SRC) determined the MTD.

  2. Part A: AZD5069 With Durvalumab MTDs (Maximum Tolerated Dose) or Recommended Doses for Dose-expansion

    Time frame: 35 days

    After completion of DLT period (35 days) for the maximum dose cohort. A CRM-based approach was used to identify the set of dose combinations where the incidence of DLT was ≤ 33%. The dose with expected DLT incidence closest and below 0.33 at this point was the "model estimated" MTD. During trial execution, the Safety Review Committee (SRC) determined the MTD.

  3. Part A: Safety and Tolerability in Terms of Adverse Events

    Time frame: At every treatment and follow up visit until disease progression, an average of 1 year.

    Number of subjects with adverse events as a measure of safety and tolerability including changes in vital signs, electrocardiograms (ECGs), safety and laboratory parameters

  4. Part B: ORR (Objective Response Rate) in Patients With IL/2L RM-SCCHN.

    Time frame: Assessed at every even-numbered cycles with RECIST until disease progression, up to 12 months.

    proportion of patients who have an objective response at a given visit. ORR will be summarised by treatment group. Objective rate is defined as a CR or PR according to RECIST 1.1.

Secondary outcomes

  1. Part A and B: AZD9150 AUC0-6h at Lead in Day-7

    Time frame: Lead in day -7, AUC from time 0 to 6h (post dose).

    If a subjects had at least one post dose PK sample they were part of PK analysis set. However, to calculate AUC, we need to have enough PK samples collected to enable AUC estimation. That is why we have a difference in actual AUC calculated number of subjects vs number of subjects participated.

  2. Part A and B: AZD9150 Cmax at Lead in Day -7

    Time frame: Lead in day -7

    If a subjects had at least one post dose PK sample they were part of PK analysis set. However, to estimate Cmax we need to have samples at end of infusion, which was not available for all the subjects in PK analysis set. That is why there is a difference between Cmax calculated number of subjects vs number of subjects participated.

  3. Part A and B: AZD9150 AUC0-6h at Cycle 2 Day 1

    Time frame: Cycle 2 day 1, AUC from time 0 to 6 h post dose

    If a subjects had at least one post dose PK sample they were part of PK analysis set. However, to calculate AUC, we need to have enough PK samples collected to enable AUC estimation. That is why we have a difference in actual AUC calculated number of subjects vs number of subjects participated.

  4. Part A and B: AZD9150 Cmax at Cycle 2 Day 1

    Time frame: Cycle 2 day 1

  5. Part A and B: AZD5069 AUC0-12h at Lead in Day -7

    Time frame: Lead in day -7, AUC from time 0 to 12h post dose

    If a subjects had at least one post dose PK sample they were part of PK analysis set. However, to calculate AUC, we need to have enough PK samples collected to enable AUC estimation. That is why we have a difference in actual AUC calculated number of subjects vs number of subjects participated.

  6. Part A and B: AZD5069 Cmax at Lead in Day -7

    Time frame: Lead in day -7

    If a subjects had at least one post dose PK sample they were part of PK analysis set. However, to estimate Cmax we need to have samples at Tmax, which was not available for all the subjects in PK analysis set. That is why there is a difference between Cmax calculated number of subjects vs number of subjects participated.

  7. Part A and B: AZD5069 Cssmax at Cycle 2 Day 1

    Time frame: Cycle 2 day 1

    If a subjects had at least one post dose PK sample they were part of PK analysis set. However, to estimate Cmax we need to have samples at around Tmax, which was not available for all the subjects in PK analysis set. That is why there is a difference between Cmax calculated number of subjects vs number of subjects participated.

  8. Part A and B: AZD5069 AUCss at Cycle 2 Day 1

    Time frame: Cycle 2 day 1

    If a subjects had at least one post dose PK sample they were part of PK analysis set. However, to calculate AUC, we need to have enough PK samples collected to enable AUC estimation. That is why we have a difference in actual AUC calculated number of subjects vs number of subjects participated.

  9. Part A and B: Durvalumab Cmax After Single Dose at Cycle 1 Day 1

    Time frame: Cycle 1 day 1

  10. Part A and B: Durvalumab Ctrough After Multiple Doses at Cycle 4 Day 1

    Time frame: Cycle 4 day 1

    If a subjects had at least one post dose PK sample they were part of PK analysis set. However, to estimate Ctrough we need to have samples at predose, which was not available for all the subjects in PK analysis set. That is why there is a difference between Ctrough calculated number of subjects vs number of subjects participated.

  11. Part A and B: Durvalumab Cmax After Multiple Doses at Cycle 8 Day 1

    Time frame: Cycle 8 day 1

    If a subjects had at least one post dose PK sample they were part of PK analysis set. However, to estimate Cmax we need to have samples at end of infusion, which was not available for all the subjects in PK analysis set. That is why there is a difference between Cmax calculated number of subjects vs number of subjects participated.

  12. Part A and B: Treme Cmax After Single Dose

    Time frame: Cycle 1 day 1

    If a subjects had at least one post dose PK sample they were part of PK analysis set. However, to estimate Cmax we need to have samples at end of infusion, which was not available for all the subjects in PK analysis set. That is why there is a difference between Cmax calculated number of subjects vs number of subjects participated.

  13. Part A and B: Treme Ctrough After Multiple Doses at Cycle 4 Day 1

    Time frame: Cycle 4 day 1

    If a subjects had at least one post dose PK sample they were part of PK analysis set. However, to estimate Ctrough we need to have samples at predose, which was not available for all the subjects in PK analysis set. That is why there is a difference between Ctrough calculated number of subjects vs number of subjects participated.
