In Patients and Methods, under the heading Treatment Plan, the sentence that reads as “Specifically, …………..that did not exceed 40 mg/m2 based on BSA as follows—BSA < 1.25 m2, 40 mg; BSA 1.25–1.5 m2, 50 mg twice daily; and BSA > 1.5 m2, 60 mg” should read as, “Specifically, the drug was administered orally twice daily for 14 consecutive days at a dose based on BSA as follows—BSA < 1.25 m2, 40 mg; BSA 1.25–1.5 m2, 50 mg; BSA ≥ 1.5 m2, 60 mg”.
