|Condition or disease||Intervention/treatment||Phase|
|Clear-cell Metastatic Renal Cell Carcinoma||Drug: Axitinib||Phase 2|
A-PREDICT is a single arm, single agent, open label, multicentre, phase II study of axitinib in patients with metastatic renal cell carcinoma of predominant clear cell histology and unsuitable for debulking nephrectomy (as judged by the treating clinician). Patients who have provided consent and have satisfied the eligibility criteria will be registered into the trial.
The starting dose of axitinib will be 5 mg twice daily by mouth, escalating to a maximum of 10mg twice daily by mouth according to tolerability of treatment, for as long as patients are deriving clinical benefit. Treatment will be paused for one week prior to percutaneous biopsy of the primary on day 1 week 9. Disease progression will be evaluated according to RECIST v1.1 criteria 8 weeks after commencing treatment, at 8 weekly intervals to 6 months and 3 monthly thereafter. Blood and tumour tissue samples will be taken prior to and during therapy to evaluate biomarkers of treatment response. Nephrectomy will be carried out on any patient who becomes suitable in the opinion of the treating clinician during the course of the trial. Where possible, tissue samples will be taken from resected specimens. Response to axitinib in marker lesions will be correlated with changes in biomarkers.

Axitinib - oral tablet twice daily until disease progression. Starting dose 5mg.
Axitinib treatment Axitinib is an oral VEGF-receptor inhibitor. Patients are prescribed a starting dose of 5mg twice daily, escalating to 10mg in absence of dose limiting toxicities.
Patients should stop axitinib treatment one week prior to day 1 week 9 percutaneous research biopsy of the primary renal tumour and restart 2-3 days post biopsy.
Doses should be taken approximately 12 hours apart and patients should be instructed to take their doses at approximately the same times each day.
Dose adjustments, including dose increase or dose reduction, are permitted and should be based on clinical judgement and the guidelines provided in the protocol.

- Freedom from progression at 6 months [ Time Frame: 6 months ]The proportion of study participants alive and progression free at 6 months (day 1 week 25 visit). Progression will be measured from the date of study entry (registration date) until the first date of either death or confirmed progressive disease according to RECIST. Patients alive and free from progression will be censored at the date of last follow-up. The proportion of patients progression free at 6 months will be reported with 95% confidence interval. In addition, progression free survival will be presented using the Kaplan Meier product limit method with median progression free survival reported. A blinded central review of CT scans will be conducted for verification purposes.
- Best overall response [ Time Frame: During treatment +30 days ]Best tumour response that is achieved during or within 30 days after termination of axitinib that is confirmed according to RECIST
- Progression free survival [ Time Frame: Study duration (assessed week 9, 17, 25, and 4 weekly until progression) ]Progression-free survival (PFS) will be measured from the date of registration until first date of either death or confirmed progressive disease according to RECIST 1.1. Time to last follow-up will be used if patient has not progressed or died and PFS time for the patient will be considered censored. A Kaplan Meier graph and median survival time will be presented.
- Overall survival [ Time Frame: Study duration (estimated median overall survival (OS) of 10.9 months) ]Overall survival will be measured from the date of registration until the date of death due to any cause. Time to last follow-up will be used if patient has not died and survival time for the patient will be considered censored.
- Safety and toxicity of axitinib (by NCI CTC grading version 4) [ Time Frame: Treatment duration (at least 4 weekly, and again at disease progression - likely to be 6 months) ]
- Number of patients who become suitable for nephrectomy as a consequence of therapy with axitinib [ Time Frame: Study duration (assessed by clinician over treatment duration which is estimated at 6 months) ]The proportion of patients who undergo nephrectomy following registration as a result of treatment with axitinib will be reported with 95% confidence intervals.
- EXPLORATORY ENDPOINT: Molecular and pathological changes in biomarkers as a consequence of axitinib therapy [ Time Frame: Treatment duration (Baseline, Day 1 week 8, and again at disease progression) ]
