A Phase I/II Clinical Trial of Belinostat (PXD101) in Combination with Doxorubicin in Patients with Soft Tissue Sarcomas.

ABSTRACT: Background. Belinostat is a novel histone deacetylase inhibitor. Primary Objectives. Maximum tolerated dose (MTD) and dose limiting toxicities (DLTs) of belinostat (Bel) in combination with doxorubicin (Dox) in solid tumours (phase I) and response rate (RR) in soft tissue sarcomas (phase II). Methods. Bel was administered as a 30-minute IV infusion on days 1-5 and on day 5 with Dox. The dose escalation schedule was as follows: cohort 1: Bel 600 mg/m(2) and 50 mg/m(2) Dox, cohort 2: Bel 600 mg/m(2) and 75 mg/m(2) Dox, cohort 3: Bel 800 mg/m(2) and 75 mg/m(2) Dox, and cohort 4: Bel 1000 mg/m(2) and 75 mg/m(2) Dox. Results. 41 patients were included (25 in phase I, 16 in phase II). Adverse events were fatigue (95%), nausea (76%), and alopecia (63%). There was one DLT, grade 3 rash/hand and fo
