简要总结
The purpose of this crossover, single-dose, bioequivalence study is to compare the rate and extent of absorption of Temozolomide after the administration of the study product (Dralitem®, Monte Verde S.A.) and the reference product (Temodal®, Schering Plough) in primary Central Nervous System patients.
详细描述
Prospective, randomized, two-period, two treatment, two-way crossover bioequivalence study of two Temozolomide oral formulations (Dralitem vs. Temodal), in primary Central Nervous System tumor patients under fasting conditions. Open label to the patients and investigators and blind to the bioanalytical and clinical laboratories.
Study plan: days -21 to 0 (Recruitment period); days 1 to 5 (Treatment period); days 6 to 21 (Safety surveillance period). Sample size: 24 patients will be randomized. The patients will be administered Temozolomide 200 mg/m2 on the first two days (Dralitem) of the treatment cycle.
They will be admitted to the study clinical site on the evening of day 2. In the morning of day 3 they will be randomized into two groups of equal size. According to the assigned random number, each subject will receive a single oral dose of Temozolomide 200mg/m2 from either Monte Verde Sociedad Anónima (SA) product (Dralitem) or from Schering-Plough product (Temodal). The single dose of 200 mg/m2 will be reached with three different Temozolomide capsule strengths: 20, 100 and 250 mg. Drugs will be administered with 200-240 ml of water in semi-sitting upright position.
The following day (day 4) each subject will receive an oral dose of Temozolomide 200 mg/m2 of the product that did not receive the day before. On days 3 and 4 after drug administration, blood samples will be obtained for pharmacokinetic evaluation. The patient will be discharged from the clinical site on day 4 after completion of sampling for pharmacokinetic analysis. On day 5, all patients will receive Temozolomide 200 mg/m2 (Dralitem).
On days 3 and 4, samples of venous blood will be withdrawn from the forearm vein of each volunteer at the following time points: 0 (pre-dose) and 0.25, 0.5, 0.75, 1.0, 1.25, 1.5, 1.75, 2.0, 2.5, 3.0, 4.0, 6.0, 8.0, 10.0 hours post-dose after each period administration. The washout period between the treatment arms was 10 hours, on days 3 and 4. Samples will be processed according to the validated method MANA (Método Analítico) - PLB (Proyecto Laboratorio Bioanalítico) 004 - TEM (Temozolomide) - 01/01. Measurement of plasma concentration of Temozolomide was performed using High Performance Liquid Chromatography (HPLC) followed by detection by tandem mass spectrometry (MS / MS).
