This was an early stopping design, Phase II, open label, exploratory proof of concept study to evaluate the activity of tasquinimod in four independent cohorts of patients with different tumour types (patients with hepatocellular, ovarian, renal cell or gastric carcinoma, each with progressive disease after standard therapies). Patients initially received 0.5 mg/day tasquinimod dose, increasing to 1 mg/day after at least 2 weeks, unless there were any individual patient safety and tolerability concerns. The treatment period continued until patient disease progression, lost to follow-up, withdrawal or death. During the treatment period, initial study visits were at Week 2, 4 and 8 (± 2 days) for the hepatocellular carcinoma, the ovarian carcinoma and the renal cell carcinoma cohorts and at Week 2, 4 and 6 (± 2 days) for the gastric carcinoma cohort, to allow careful safety monitoring and to facilitate the identification of the individually tolerated dose. After Week 8, when most patients should have reached their tolerable dose, visit frequency was decreased as follows: at Week 16 and 24 (± 2 days) for the hepatocellular carcinoma, the ovarian carcinoma and the renal cell carcinoma cohorts; and at Week 12, 18 and 24 (± 2 days) for the gastric carcinoma cohort. Thereafter visits were once every 8 weeks (± 2 days) for all cohorts. An end of study treatment/withdrawal (EoST/WD) Visit was to be performed at least 14 days after the last dose of study treatment, and/or before treatment with any alternative antitumour therapy was started. Patients who stopped study treatment before disease progression were to be followed up with tumour imaging every 8 weeks until disease progression. Each patient was subsequently followed up for survival (by visit or telephone call) every 3 months after the EoST/WD Visit until death, lost to follow-up, or withdrawal of consent, or until all surviving patients had been followed-up for at least 9 months after their last administration of study treatment.~The clinical activity of tasquinimod was evaluated independently in each cohort of patients of the four different tumour types. Data were presented as of the following study cut-off dates:~Hepatocellular carcinoma cohort: 03 December 2014 (efficacy data); 11 April 2016 (safety data).~Ovarian carcinoma cohort: 27 November 2013 (efficacy data); 05 October 2015 (safety data).~Renal cell carcinoma cohort: 04 December 2013.~Gastric carcinoma cohort: 27 September 2013.
This was an exploratory proof of concept study to determine the clinical activity of tasquinimod in patients with advanced or metastatic hepatocellular carcinoma, ovarian carcinoma, renal cell carcinoma and gastric carcinoma who had progressed after standard therapies.
