Abstract
Purpose
Treatment of patients with recurrent ovarian cancer remains a challenge, and there is a need for new and more effective agents. A phase I-II study was designed to determine the recommended dose (RD) and the anti-tumour effect of a prolonged administration of elacytarabine, the elaidic ester of cytarabine, in patients with refractory/resistant recurrent ovarian cancer.
Experimental design
The primary objective of the dose escalation phase I part was to determine the RD for elacytarabine when given twice for five consecutive days in a 4-week schedule, D1-5 and D8(+2)-12(+2) q4w. Three to six patients were to be enrolled at each dose level. The start dose was elacytarabine 75 mg/m2/day. The phase II part was designed as a two-step study based on response.
Results
A total of 28 patients entered the study, 17 patients in the phase I part and 11# patients in phase II. Three dose levels were tested: 75 mg/m2/day in 3 patients, 100 mg/m2/day in 7 + 11# patients, and 125 mg/m2/day in 7 patients. Three (17.6%) patients in phase I experienced a dose limiting toxicity (DLT), all at the 125 mg/m2/day dose level, establishing the lower dose of 100 mg/m2/day as the RD. The DLTs were neutropenia grade 4 according to the Common Terminology Criteria for Adverse Events (CTCAE) and thrombocytopenia grade 4 (2 patients), and vomiting grade 2 with hospitalisation and hypokalaemia grade 3 (1 patient). The best response was a clinically meaningful stabilization observed in 3 patients. In two of them, the disease stabilization exceeded the previous platinum-free interval (PFI).
Conclusions
The RD for elacytarabine was 100 mg/m2/day, D1-5 and D8-12 q4w. The safety profile was comparable to the safety profiles reported in previous clinical studies with elacytarabine in solid tumours. Despite some longer-lasting disease stabilisations, two of them exceeding the previous progression-free interval, further investigations of elacytarabine in the ovarian cancer indication are not warranted.
