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
3.Histologically 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 treatment with only 1 systemic palliative regimen for recurrent or metastatic disease that must have contained a platinum agent. Patients who have only received chemo-radiation with curative intent for treatment of their locally advanced disease or recurrent disease are not eligible.
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 newly acquired 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 SCCHN by the Ventana SP263 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 analytically validated Ventana assay as a part of the screening process for another AstraZeneca/MedImmune study, this test result can be used for the determination of eligibility.
Note: A positive PD-L1 sample for eligibility is defined by the presence of membrane staining of any intensity in ≥25% of tumor cells using the Ventana assay.
7.World Health Organization (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. Prior 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 as:
- Hemoglobin ≥9 g/dL
- Absolute neutrophil count ≥1500/mm3
- Platelet count ≥100000/mm3
- Serum bilirubin ≤1.5 × the upper limit of normal (ULN). This will not apply to patients with confirmed Gilbert's syndrome (persistent or recurrent hyperbilirubinemia [predominantly unconjugated bilirubin] in the absence of evidence of hemolysis or hepatic pathology), who will be allowed in consultation with their physician.
- ALT and AST ≤2.5 × ULN; for patients with hepatic metastases, ALT and AST ≤5 × ULN
- Calculated creatinine clearance ≥40 mL/min as determined by
Cockcroft-Gault (using actual body weight)
11.Evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal patients. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause.
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 and if they have luteinizing hormone and folliclestimulating 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, had radiation-induced oophorectomy with last menses >1 year ago, had chemotherapy-induced menopause with >1 year interval since last menses, or underwent surgical sterilization (bilateral ophorectomy or hysterectomy). |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is the objective response rate (ORR). ORR is defined as the number (%) of patients with a confirmed overall response of complete response (CR) or partial response (PR) and will be based on all treated patients who have measurable disease at baseline per BICR. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
A confirmed response of confirmed or partial response means that a response of complete or partial response is recorded at one visit and confirmed by repeat imaging not less than 4 weeks after the visit when the response was first observed with no evidence of progression between the initial and confirmed or partial response confirmation visit. Therefore, data obtained up until progression, or the last evaluable assessment in the absence of progression, will be included in the assessment of objective response rate. |
|
E.5.2 | Secondary end point(s) |
1. Duration of response (DoR) - time from the date of first documented response until the first date of documented progression or death in the absence of disease progression.
2. Disease control rate (DCR) - percentage of patients who have a best objective response (BoR) of confirmed or partial response in the first 4 or 12 months or who have demonstrated stable disease (SD) for a minimum interval of 16 or 52 weeks following the start of treatment.
3. Progression-free survival (PFS) - time from the date of first dose until the date of objective disease progression or death.
4. Overall survival (OS) - time from the date of enrollment until death due to any cause.
5. Best objective response (BoR) - the best response a patient has had during their time in the
study up until RECIST 1.1 progression or confirmed progression or the last evaluable assessment. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
1. DoR - time of the initial response will be defined as the latest of the dates contributing towards the first visit response of PR or CR.
2. DCR - first 4 or first 12 months.
3. PFS time will be derived based on scan/assessment dates.
4. OS - Survival calls will be made in the week following the date of data cut-off for the analysis, and if patients are confirmed to be alive or if the death date is post the data cut-off date, these patients will be censored at the date of data cut-off.
5. BoR - for deaths occuring ≤17 weeks after enrollment BoR will be assigned to the progressive disease (PD) category and for deaths occuring >17 weeks after enrollment BoR will be assigned to the not evaluable (NE) category.
