Study information

Scientific title

Docetaxel +/- AZD6244 in Melanoma - A double blind randomised phase 2 trial of docetaxel with or without AZD6244 in wt BRAF advanced melanoma

Acronym

DOC-MEK

Study hypothesis

This is a randomised, double-blind placebo controlled phase 2 trial. Patient will be randomly assigned 1:1 between two treatment arms. They will receive either docetaxel 75 mg/m^2 intravenously (IV) and placebo given twice daily (bd), or AZD6244 75 mg bd daily with docetaxel 75 mg/m^2 IV. Docetaxel will be administered every 3 weeks for a maximum 6 cycles, but AZD6244/placebo may be continued beyond this, until disease progression.

The objective is to assess whether the combination of AZD6244 with docetaxel is worthy of evaluation in a definitive randomised study, with the null hypothesis being that the combination has activity similar to that of docetaxel alone in this population. After consent has been obtained mutational analysis of tumour BRAF will be performed on archival tumour tissue, where this information is not already known, to assess eligibility for the study. If there is no archival tissue a fresh biopsy will be requested from the patient. A blood sample will also be taken for future genetic analysis.

Once taking part in the trial patients will need to attend their oncology unit regularly for monitoring and the delivery of treatment. Patients will undergo complete physical examination at screening, on C1D1, C1D8, C1D15, C2D1, C2D8 and day 1 of every subsequent cycle. Blood for haematology, biochemistry and clotting will be taken at each of these visits. A 12-lead electrocardiogram (ECG) will be performed at screening. Disease assessment will be by computed tomography (CT) scanning using modified Response Evaluation Criteria in Solid Tumours (RECIST) criteria after 9 and 18 weeks, then every 3 months until disease progression.

Condition

Topic: National Cancer Research Network; Subtopic: Melanoma; Disease: Melanoma

Intervention

Patients will receive 75 mg AZD6244 or placebo orally twice a day on a continuous schedule. Capsules should be taken whole and not opened or crushed. They should be taken on an empty stomach (no food or drink for 2 hours before or 1 hour after treatment), with approximately 240 ml of water. Doses should be taken approximately 12 hours apart. Wherever possible doses should not be missed but if a dose is missed then the next dose should be taken at the allotted time.

Docetaxel arm: Patients will receive docetaxel 75 mg/m2, rounded to the nearest 10 mg, based on the most recent body surface area, as a 1-hour IV infusion in 250 ml of either 5% glucose solution or 0.9% sodium chloride solution. Standard pre-medication with steroids should be given, consisting of dexamethasone 8 mg b.d. for 3 days starting 1 day prior to docetaxel administration. Treatment will be given on day 1 and every 3 weeks for up to 6 cycles. The dose of docetaxel may be reduced or delayed if necessary.
