E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1.

The second co-primary objective investigate Akynzeo and dexamethasone in terms of the proportion of subjects with no vomiting, i.e. sustained no emesis rate - during five weeks of fractionated radiotherapy and concomitant weekly cisplatin at a dose of ≥ 40 mg/m2.

To investigate Akynzeo and dexamethasone in terms of the proportion of subjects with no significant nausea (none or mild nausea) in the 5 days and the 35 days following initiation of fractionated radiotherapy and concomitant weekly cisplatin at a dose of ≥ 40 mg/m2. 3. To investigate Akynzeo and dexamethasone in terms of the proportion of subjects with no nausea in the 5 days and the 35 days following initiation of fractionated radiotherapy and concomitant weekly cisplatin at a dose of ≥ 40 mg/m2. 4.

1. The patient has a current malignant diagnosis other than cervical cancer, with exception of non-melanoma skin cancers. 2. The patient is pregnant or lactating. 3. The patient has experienced emesis (i.e., vomiting and/or retching) or clinically significant nausea (defined as nausea graded as moderate or severe) in the 24 hours preceding the first dose of study medication. 4. The patient has a history active peptic ulcer disease, gastrointestinal obstruction, gastrointestinal carcinoma, increased intracranial pressure, hypercalcemia, or any uncontrolled medical condition (other than malignancy) which in the opinion of the Investigator may confound the results of the study, represent another potential etiology for emesis and nausea (other than CINV/RINV) or pose an unwarranted risk to the patient. 5.

The patient has received an investigational drug in the previous 30 days or is scheduled to receive any investigational drug during the study period. 8.

Opiate drugs for cancer pain will be permitted if the patient has been on a stable dose and has not experienced emesis or clinically significant nausea from the narcotics in the 24 hours preceding the first dose of study medication. 9. The patient has taken/received any medication with known or potential antiemetic activity within the 24-hour period prior to receiving study drugs. This includes, but is not limited to: • 5-HT3 receptor antagonists (e.g., ondansetron, granisetron, dolasetron, tropisetron, ramosetron). Palonosetron is not permitted within 7 days prior to receiving study drugs. • Benzamide / benzamide derivatives (e.g., metoclopramide, alizapride). • Benzodiazepines (except if the patient is receiving such medication for sleep or anxiety and has been on a stable dose for at least seven days prior to the first dose of study medications). • Phenothiazines (e.g., prochlorperazine, promethazine, metopimazine, fluphenazine, perphenazine, thiethylperazine, chlorpromazine). • Butyrophenone (e.g., haloperidol, droperidol). • Corticosteroids (e.g., dexamethasone, methylprednisolone, prednisolone; with the exception of topical steroids for skin disorders, inhaled steroids for respiratory disorders). • Anticholinergics (e.g., scopolamine). • Antihistamines (e.g., cyclizine, hydroxyzine, diphenhydramine). • Domperidone. • Cannabinoids. • Mirtazapine. • Olanzapine. 10.

E.5 End points |
E.5.1 | Primary end point(s) |
1. The first co-primary objective is to explore the safety of an antiemetic regimen consisting of Akynzeo and dexamethasone during five weeks of fractionated (5 days a week) radiotherapy and concomitant weekly cisplatin at a dose of ≥ 40 mg/m2. 2. The second co-primary objective investigate Akynzeo and dexamethasone in terms of the proportion of subjects with no vomiting, i.e. sustained no emesis rate - during five weeks of fractionated radiotherapy and concomitant weekly cisplatin at a dose of ≥ 40 mg/m2. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
A study population of 80 patients is considered reasonable for the purpose of this study. Assuming a 49 % SNE rate for the previous standard antiemetic treatment, it is calculated that 61 patients should be included to test a 17 % difference between the previous standard treatment and the treatment including Akynzeo with 80% power and a two-sided level of significance of 0.05 (Wald test). A total of 80 patients will therefore be enrolled to ensure at least 61 eligible patients for full 5 weeks assessment and evaluation of the SNE rate.
