E.3 | Principal inclusion criteria |
1) Histologically proven HNSCC of the hypopharynx, oropharynx, oral cavity ,supraglottis or larynx (except T1 glottic tumours) for whom surgery with curative intent ± post-operative radiotherapy or chemoradiotherapy is considered the primary treatment of choice. Surgery should be scheduled to take place no sooner than 21 days and no later than 30 days post first dose of AMG 319 or placebo.
Patients presenting with recurrence can be considered for inclusion, as long as their previous treatment did not include radiotherapy ± chemotherapy or any other anti-cancer therapy i.e. treated with surgery alone and this did not take place within 6 months prior to trial entry.
Patients presenting with a second primary HNSCC can be considered for inclusion, as long as any previous radiotherapy, chemotherapy or any other anti-cancer therapy was completed more than 5 years prior to trial entry.
2) Patients considered fit to undergo curative resection surgery.
3) Haematological and biochemical indices within the ranges shown below. These measurements must be performed within eight days prior to the patient receiving the first dose of AMG 319 or placebo.
Laboratory Test Value required
•Haemoglobin (Hb) ≥ 100 g/L
•Absolute neutrophil count ≥ 1.5 x 10^9/L
•Platelet count ≥ 100 x 10^9/L
•Bilirubin ≤ 1.5 x upper limit of normal ULN
•Alanine aminotransferase (ALT)
and/or aspartate aminotransferase (AST) ≤ 2.5 x ULN
•Alkaline Phosphatase (alk phos/ALP) ≤ 2.5 x ULN
•Amylase ≤ 2 x ULN
•Calculated creatinine clearance (using
the Wright or Cockcroft-Gault formula) ≥ 50 mL/min
4) 18 years or over at the time informed consent is given.
5) Written (signed and dated) informed consent and capable of co-operating with treatment and follow-up.
|
|
E.4 | Principal exclusion criteria |
1) Prior radiotherapy, immunotherapy, chemotherapy or other anti-cancer therapy (excluding surgery) for current HNSCC.
2) Patients should be excluded from the trial if they have active or previous malignancies of other types which in the investigator's opinion would mean they are not a good candidate for the clinical trial.
3) Female patients who are able to become pregnant (or are already pregnant or lactating). However, those patients who have a negative serum or urine pregnancy test before enrolment and agree to use two forms of contraception (one effective form plus a barrier method) [oral, injected or implanted hormonal contraception and condom; intra-uterine device and condom; diaphragm with spermicidal gel and condom] or agree to sexual abstinence*, effective from the first administration of AMG 319 throughout the trial and for six months afterwards are considered eligible.
4) Male patients with partners of child-bearing potential (unless they agree to take measures not to father children by using a barrier method of contraception [condom plus spermicide] or to sexual abstinence* effective from the first administration of AMG 319, throughout the trial and for six months afterwards. Men with partners of child-bearing potential must also be willing to ensure that their partner uses an effective method of contraception for the same duration for example, hormonal contraception, intrauterine device, diaphragm with spermicidal gel or sexual abstinence). Men with pregnant or lactating partners must be advised to use barrier method contraception (for example, condom plus spermicidal gel) to prevent exposure of the foetus or neonate.
5) Patients unable to swallow oral medications (trial medication must not be chewed, crushed, dissolved or divided).
6) Major thoracic or abdominal surgery from which the patient has not yet recovered.
7) At high medical risk because of non-malignant systemic disease including active uncontrolled infection.
8) Active or uncontrolled auto-immune disease which may require systemic immunomodulator therapy during the trial treatment period. Exceptions to this are atopic dermatitis and psoriasis not requiring systemic treatment.
9) Long term use of systemic corticosteroids with the exception of replacement treatment. Discontinuation of steroid use within seven days prior to receiving the first dose of AMG 319 or placebo would be acceptable. Inhaled and topical steroids are permitted.
10) Known to be serologically positive for hepatitis B, hepatitis C or human immunodeficiency
virus (HIV). If there is clinical suspicion of infection this must be ruled out by appropriate serological and PCR testing.
11) QTc > 470 msec (Friderica [QTc F] correction) or a history or family history of QT prolongation.
12) Regular and/or prolonged treatment with medications known to cause QTc interval prolongation within seven days prior to receiving the first dose of AMG 319 or placebo.
13) Is a participant or plans to participate in another interventional clinical trial, whilst taking part in this Phase IIa trial of AMG 319. Participation in an observational trial or interventional clinical trial which does not involve administration of an IMP would be acceptable
14) Any other condition which in the Investigator’s opinion would not make the patient a good candidate for the clinical trial.
* Abstinence is only considered to be an acceptable method of contraception when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g. calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception. |
