Summary

Anal cancer is a relatively uncommon disease and there is currently no standard chemotherapy treatment for patients with inoperable locally recurrent or metastatic disease. The aim of

this phase II study is compare two well known and largely used chemotherapy regimens -

Cisplatin plus 5-fluorouracil vs Carboplatin plus Paclitaxel. The result of this study will set a standard of care for this disease and provide useful information for future Phase III trials.

Clinical Details

Official title: An International Multicentre Open Label Randomised Phase II Advanced Anal Cancer Trial Comparing Cisplatin Plus 5 FU vs Carboplatin Plus Weekly Paclitaxel in Patients With Inoperable Locally Recurrent or Metastatic Disease

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Best overall response rate by 24 weeks post treatment

Secondary outcome:

Feasibility of conducting a multicentre, international study on squamous cell carcinoma of the anus and recruiting within a reasonable time frame.

Toxicity

Progression-free survival

Overall survival

Disease control rate

Best overall response rate of non-irradiated lesions

Anti-tumour activity and magnitude of tumour response

Quality of Life

Identification of potential tumour biomarker

Detailed description: Study design: This is an international, multicentre, open label, randomised phase II trial. Patients will be randomised to receive either cisplatin plus 5-FU or carboplatin plus weekly paclitaxel. Region (Europe, North America, South America & Australia), (Eastern Cooperative Oncology Group- ECOG) ECOG performance status (PS) (0-1 vs. 2), HIV status (positive vs. negative) and extent of disease (locally recurrent vs. metastatic) will be used as stratification factors. Overall response rate is the primary endpoint. Indication: First line treatment of patients with inoperable locally recurrent or metastatic squamous cell carcinoma of the anus. Length of study: Recruitment should be completed within 3 years. The estimated recruitment rate is between 4-6 patients per month once it is established at multiple centres. Primary Objective: To evaluate best overall response rate by 24 weeks post treatment in the cisplatin plus 5-fluorouracil arm versus the carboplatin plus weekly paclitaxel arm

Secondary Objectives: To evaluate: - Progression-free survival - Overall survival - Disease

control rate (stable disease or better) at 12 and 24 weeks - Best overall response of

metastatic lesions - Toxicity (graded according to the National Cancer Institute Common

Terminology Criteria for Adverse Events (NCI CTCAE Version 4) - Quality of Life (using EORTC

QLQ-C30 version 3 and EQ-5D-5L questionnaires). To assess: The feasibility of conducting a multicentre international study on squamous cell carcinoma of the anus and recruit within a reasonable time frame. Exploratory Objective: Explorative biomarker analysis including the collection of archived tumour tissue and blood sample at baseline and upon progression.

Eligibility

Current or recent (within 30 days of first study dosing) treatment with another investigational drug or participation in another investigational study. 4. Documented or symptomatic brain metastases and/or central nervous system metastases or leptomeningeal disease. 5. Surgery or palliative radiotherapy within 28 days of randomisation. 6. Clinically significant (i. e. active) cardiac disease (e. g. symptomatic coronary artery disease, uncontrolled cardiac arrhythmia, or myocardial infarction within the last 6 months). Any history of clinically significant cardiac failure. 7. History of interstitial lung disease (e. g. pneumonitis or pulmonary fibrosis) or evidence of interstitial lung disease on baseline chest CT scan. 8.
