E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare the duration of overall survival in patients who are randomized at enrollment to treatment with one of two trastuzumab dosing regimens (loading dose of 8mg/kg) followed by either 6mg/kg or 10mg/kg maintenance doses given every 3 weeks, plus cisplatin and capecitabine. |
Comparar la duración de la supervivencia global (SG) en los pacientes randomizados tras su inclusión en el estudio para recibir tratamiento con uno de los dos regímenes de administración de trastuzumab (dosis inicial de 8 mg/kg, seguida de dosis de mantenimiento de 6 mg/kg o 10 mg/kg administradas cada 3 semanas), en combinación con cisplatino y capecitabina. |
|
E.2.2 | Secondary objectives of the trial |
? To compare the duration of overall survival (OS) in patients on the two trastuzumab treatment arms who are found to have trastuzumab Cmin values < 12 ?g/mL on Cycle 1 Day 21. ? To assess trastuzumab concentrations during treatment Cycle 1 and trastuzumab Cmin(Day 21) values in additional treatment cycles through Cycle 11 (ie, pre-dose concentration before Cycle 12) or until disease progression (whatever occurs first) for the two dosing regimens. ? To evaluate the safety and tolerability of trastuzumab for the two dosing regimens. ? To compare the duration of progression-free survival (PFS) and the overall objective response rate (ORR) in patients on the two trastuzumab treatment arms who are found to have trastuzumab Cmin values < 12 ?g/mL on treatment Cycle 1 Day 21. |
?Comparar la duración de la SG en los pacientes de los dos grupos de tratamiento con trastuzumab en los que se observen valores de la Cmin de trastuzumab < 12 µg/ml el día 21 del ciclo 1. ?Evaluar las concentraciones de trastuzumab durante el primer ciclo de tratamiento y los valores de la Cmin de trastuzumab (día 21) en los ciclos de tratamiento adicionales, hasta el ciclo 11 (es decir, la concentración previa a la administración de la dosis alcanzada antes del ciclo 12) o hasta que se manifieste progresión de la enfermedad (dependiendo de lo que ocurra antes) en los dos regímenes de tratamiento. ?Evaluar la seguridad y la tolerancia de trastuzumab en los dos regímenes de administración. Comparar la duración de la SLP y el IRO en los pacientes de los dos grupos de tratamiento con trastuzumab en los que se observen valores de la Cmin de trastuzumab < 12 µg/ml el día 21 del ciclo 1 de tratamiento. |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Evaluation of the pharmacokinetics of trastuzumab administered every three weeks at two different maintenance dose levels to patients with metastatic HER2-positive gastric or gastro-esophageal junction adenocarcinoma. Protocol BO27798PK version A dated 23 June 2011. The objectives are ? To characterize the serum trastuzumab concentration-vs-time (C-vs-T) profiles in the study population following the initial loading dose (8 mg/kg) at Cycle 1, and the maintenance doses (6 mg/kg or 10 mg/kg q3W) at Cycles 2 and 4. ? To evaluate the accumulation of peak and trough serum trastuzumab concentrations following selected sequential doses given every three weeks, up to the projected steady-state (Cycles 1, 2, 3, 4, 5, 7, 9, and 11). ? To describe the pharmacokinetic (PK) of trastuzumab in patients with metastatic gastric/GEJ cancer and compare to previous observations in patients with metastatic breast cancer and gastric cancer. ? To support development and refinement of an integrated population-based model for the PK disposition of trastuzumab in cancer patients, using data from multiple dosing regimens and disease types. |

The end of the study will be when the targeted number of events for the final analysis of OS (379/400) is reached and the last patient has completed 6 months of cardiac safety follow-up thereafter, or when the study is terminated by the Sponsor, whichever occurs first. Patients still receiving trastuzumab at the time of study end and who do not have PD will be allowed to continue trastuzumab until progression of disease under a separate extension protocol. |
El estudio terminará cuando se haya alcanzado el número de acontecimientos pretendido para el análisis final de la SG (379/400) y el último paciente haya completado posteriormente la fase de seguimiento de la seguridad cardíaca de 6 meses o cuando el promotor decida terminar el estudio, dependiendo de lo que ocurra antes. |
