Nintedanib and Weekly Docetaxel in Lung Adenocarcinoma

Maximum Tolerated Dose (MTD) of Nintedanib Administered in Combination With Docetaxel

Maximum tolerated dose (MTD) of nintedanib administered in combination with docetaxel. The MTD was defined as the highest dose combination studied for which the incidence of DLTs was no more than 1 out of 6 subjects experiencing a DLT during the first treatment cycle i.e. the incidence of DLTs was no more than 17%. In case dose escalation reached dose level 3 (200 mg bid nintedanib administered without interruption on days of docetaxel infusion) and no more than 1 out of 6 subjects experienced a DLT during the first 28-day cycle at this dose level, dose level 3 was considered the MTD.

Time frame: First treatment cycle, the first 28 days following the start of trial medication.
