E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
AstraZeneca intends to perform genetic research in the MEDI4736 clinical development program to explore how genetic variations may affect the clinical parameters associated with this drug. Collection of DNA samples from populations with well-described clinical characteristics may lead to improvements in the design and interpretation of clinical trials and, possibly, to genetically guided treatment strategies. The objective of this research is to collect and store DNA, derived from a blood sample, for future exploratory research into genes/genetic variations that may influence response, ie, distribution, safety, tolerability, and efficacy of MEDI4736, and/or susceptibility to SCCHN. All enrolled patients who take part in the main study will be asked to participate in this genetic research. Participation is voluntary. For inclusion in this genetic research, patients must fulfil all of the inclusion criteria described in the main body of the Clinical Study Protocol and provide informed consent for the genetic sampling and analyses. Blood samples will ideally be collected during the screening/baseline period. If for any reason the sample is not drawn during the screening/baseline period, it should be taken as soon as possible, but not later than the last study visit. Only 1 sample should be collected per patient for genetics during the study. |
|
E.3 | Principal inclusion criteria |
1. Age ≥18 years at the time of screening
2. Written informed consent and any locally required authorization obtained from the patient/legal
representative prior to performing any protocol-related procedures, including screening evaluations. (For patients aged <20 years and enrolling in Japan, a written informed consent should be obtained from the patient and his or her legally acceptable representative.)
3. Histologically or cytologically confirmed recurrent or metastatic SCCHN (oral cavity, oropharynx, hypopharynx, or larynx) not amenable to therapy with curative intent (surgery or radiation therapy with or without chemotherapy). Patients who refuse radical resection are eligible.
4. Tumor progression or recurrence during or after only one pallative
systemic treatment regimen for recurrent or metastatic disease that
must have contained a platinum agent OR progression within 6 months
of the last dose of platinum given as part of multimodality therapy with
curative intent.
5. Able and willing to give valid written consent to provide newly
acquired tumor tissue (preferred) or archival tissue (≤3 years old) for
the purpose of establishing PD-L1 status. Tumor lesions used for fresh
biopsies should not be the same lesions used as RECIST 1.1 target
lesions, unless there are no other lesions suitable for biopsy.
6. Confirmed PD-L1-positive or -negative SCCHN by the Ventana PD-L1
SP263 IHC assay on newly acquired tumor tissue (preferred) or archival
tissue (≤3 years old)
-If the patient's PD-L1 status has already been assessed using the
Ventana PD-L1 SP263 IHC assay as a part of the screening process for
another AstraZeneca/MedImmune study, this test result can be used for
the determination of eligibility, provided the PD-L1 status was obtained
on tissue within the last 3 years.
7. WHO/Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 at enrollment
8. At least 1 lesion, not previously irradiated, that can be accurately measured at baseline as ≥10 mm in the longest diameter (except lymph nodes which must have a short axis ≥15 mm) with CT or MRI and that is suitable for accurate repeated measurements as per RECIST 1.1 guidelines. Lesions in a previously irradiated field can be used as measurable disease provided that there has been demonstrated progression in the lesion.
9. Patients must have no prior exposure to immune-mediated therapy, including other anti-CTLA-4, anti-PD-1, anti-PD-L1, or anti-PD-L2 antibodies, excluding therapeutic anticancer vaccines. Exposure to other investigational agents may be permitted after discussion with the Sponsor.
10. Adequate organ and marrow function independent of transfusion for at least 7 days prior to Screening and independent of growth factor support for at least 14 days prior to screening, defined below. Patients
requiring routine transfusions should be discussed with the Sponsor.
-Hemoglobin ≥9 g/dL

The following age-specific requirements apply:
- Women ≥50 years of age would be considered post-menopausal if
they have been amenorrheic for 12 months or more following cessation
of exogenous hormonal treatments or if they have luteinizing hormone
and follicle-stimulating hormone levels in the post-menopausal range for
the institution.
-Women <50 years of age would be considered post-menopausal if
they have been amenorrheic for 12 months or more following cessation
of all exogenous hormonal treatments and have luteinizing hormone and
follicle-stimulating hormone levels in the post-menopausal range for the
institution, had radiation-induced oophorectomy with last menses >1
year ago, or had chemotherapy-induced menopause with >1 year
interval since last menses, or underwent surgical sterilization (bilateral
oophorectomy or hysterectomy). |

E.5 End points |
E.5.1 | Primary end point(s) |
- Overall survival: OS is defined as the time from the date of
randomization until death due to any cause. Any patient not known to
have died at the time of analysis will be censored based on the last
recorded date on which the patient was known to be alive. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
-OS: time from the date of randomization until death due to any cause.
|
|
E.5.2 | Secondary end point(s) |
- Progression-free survival: PFS PFS (per RECIST 1.1 as assessed by the
site Investigator) will be defined as the time from the date of
randomization until the date of objective disease progression or death (by any cause in the absence of progression) regardless of whether the
patient withdraws from therapy or receives another anticancer therapy
prior to progression (ie, date of event or censoring - date of
randomization +1). Patients who have not progressed or died at the time
of analysis will be censored at the time of the latest date of assessment
from their last evaluable RECIST 1.1 assessment. However, if the patient
progresses or dies after 2 or more missed visits, the patient will be
censored at the time of the latest evaluable RECIST 1.1 assessment prior
to the 2 missed visits. If the patient has no evaluable visits or does not
have baseline data, they will be censored at Day 1 unless they die within
2 visits of baseline, then they will be treated as an event with date of
death as the event date.
- Objective response rate: ORR (per RECIST 1.1 as assessed by the site
Investigator) is defined as the number (%) of patients with at least 1
visit response of CR or PR and will be based on a subset of all
randomized patients
- Duration of response: DoR is defined as the time from the date of first
documented response until the first date of documented progression or
death in the absence of disease progression.
- Disease control rate: DCR at 6 months is defined as the percentage of
patients who have a best objective response (BoR) of CR or PR in the
first 6 months or who have demonstrated SD for a minimum interval of
24 weeks (-7 days, ie, 161 days) following the start of treatment with
IP. DCR at 12 months is defined as the percentage of patients who have
a BoR of CR or PR in the first 12 months or who have demonstrated SD
for a minimum interval of 48 weeks (-7 days, ie, 329 days) following the
start of treatment with IP.
- Proportion of patients alive and progression free at 6 months
- Proportion of patients alive and progression free at 12 months
- Proportion of patients alive at 12 months
- Proportion of patients alive at 18 months
- Proportion of patients alive at 24 months
- Time from randomization to the first subsequent therapy (TFST) or death
- Best objective response: BoR is the best response a patient has had
during their time in the study up until RECIST 1.1 |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
-PFS: time from the date of randomization until the date of objective
disease progression or death.
TFST or death: time from the date of randomization or the earlier of either the start date of the first subsequent anticancer therapy after discontinuation of randomized treatment or the date of death
Other secondary endpoints: Duration of study for individual patients |
