Abstract

PURPOSE:

A phase I dose escalation study was performed to determine the maximum tolerated dose (MTD) of intercalated dosing of BMS-690514, a reversible oral panHER/VEGF receptor inhibitor, combined with paclitaxel/carboplatin (PC) in advanced solid tumors. Secondary endpoints included safety, pharmacokinetics (PK), exploratory pharmacodynamics (PD), and preliminary efficacy.

EXPERIMENTAL DESIGN:

Patients received fixed doses of P (200 mg/m(2)) and C (AUC 6 mg/mL min) q21 days with intercalated BMS-690514 (Days 4-19) starting at 100 mg/day and increasing by 50 mg/day using a 3 + 3 dose escalation design until the MTD was reached. Twenty additional patients were enrolled in the expansion cohort at the recommended phase II dose (RP2D).

RESULTS:

The MTD was reached at 150 mg/day. DLTs included grade 3 thrombosis at 100 mg (1 patient) and grade 3 diarrhea at 150 mg (1 patient) and 200 mg (2 patients). Serious adverse events (AEs) occurring in 20/37 patients included neutropenia (n = 5), diarrhea (n = 4), pulmonary embolism (n = 3), and simultaneous dehydration, acute renal failure, and febrile neutropenia (n = 2). BMS-690514-related AEs included diarrhea (97 %), acneiform rash (60 %), fatigue (43 %), nausea (30 %), and anorexia (30 %). There were no treatment-related deaths. Sequential intermittent administration of PC did not affect the PK of BMS-690514. Of the 32 patients evaluable for efficacy, there were 12 partial responses including five patients with non-small-cell lung cancer and 12 patients with stable disease.

CONCLUSIONS:

The MTD of intercalated BMS-609514 combined with PC was 150 mg/day. This approach was tolerable with manageable toxicities and antitumor activity in a variety of solid tumor types.
