Abstract

Purpose: The goals of this study were to determine the safety, toxicity, and pharmacokinetics of TAC-101, a novel synthetic retinoic acid receptor-alpha (RAR-α) selective retinoid, in patients with advanced cancer. Patients and Methods: Twenty-nine patients at two centers received oral TAC-101 at doses ranging from 12 to 34 mg/m2/d. Pharmacokinetic sampling was performed on days 1 and 28. Results: The most frequent toxicities were myalgia/arthralgia, fatigue, and triglyceridemia. No dose-limiting toxicities were observed within the first 28 days up to 28 mg/m2. However, seven of 21 patients experienced venous thromboembolic events (VTEs) during TAC-101 treatment. Eight additional patients who received 34 mg/m2 were treated after a hypercoagulable work-up to exclude potential risk factors for VTE, and two of eight patients subsequently experienced VTEs. The maximum tolerated dose was exceeded at 34 mg/m2/d within the first 28 days, with one grade 3 hypertriglyceridemia, two grade 3 myalgia/arthralgia, and one grade 3 fatigue. One patient with advanced non-small-cell lung cancer had a complete response. No other responses were observed. No autoinduction of metabolism was observed with dosing over 28 days. Conclusion: This is the first human clinical study with TAC-101, a RAR-α selective retinoid. Musculoskeletal toxicity and hypertriglyceridemia were observed characteristics of previously studied retinoids. The recommended phase II dose is 24 mg/m2 with this treatment schedule. Alternative treatment schedules and prospective evaluation of thrombotic risk will be investigated in subsequent studies.
