1. Randomization to the date of first documented progression of disease or death from any cause (estimated as up to 3 years) |
1. Período comprendido entre la fecha de aleatorización y la fecha en la que se documente por primera vez la progresión de la enfermedad o la fecha de la muerte por cualquier causa (se estima que como máximo será de 3 años) |
|
E.5.2 | Secondary end point(s) |
2. Overall Survival (OS) 3. Objective Response Rate (ORR): Percentage of Participants Who Achieve a Confirmed Best Overall Response of Complete Response (CR) or Partial Response (PR) 4. Duration of Response (DoR) 5. Clinical Benefit Rate (CBR): Percentage of Participants Who Achieve a Best Overall Response of CR, PR or Stable Disease for greater than or equal to (≥) 24 weeks 6. PFS by Estrogen Receptor 1 Gene (ESR1) Mutation Status in Plasma Investigator-assessed PFS by ESR1 mutation status in plasma 7. Progression Free Survival (PFS) by blinded independent review 8. Patient Reported Outcomes (PRO): Time to Worsening of "Worst Pain" Measured by the Worst Pain Numeric Rating Scale (NRS). NRS is a single item, participant-administered, 11-point horizontal scale anchored at 0 and 10, with 0 representing "no pain" and 10 representing "pain as bad as you can imagine." 9. Pharmacokinetics (PK): Steady State Plasma Concentrations of LY3484356 |
2. Supervivencia global (SG) 3. Tasa de respuestas objetivas (TRO): porcentaje de pacientes que alcancen una mejor respuesta global confirmada de respuesta completa (RC) o respuesta parcial (RP) 4. Duración de la respuesta (DdR) 5. Tasa de beneficio clínico (TBC): Porcentaje de participantes que alcancen una mejor respuesta global de RC, RP o enfermedad estable durante ≥ 24 semanas. 6. SSP de acuerdo con el estado mutacional del gen 1 del receptor de estrógenos (ESR1) en el plasma y la evaluación del investigador; SSP en función del estado mutacional del ESR1 en el plasma 7. Supervivencia sin progresión (SSP) de acuerdo con una revisión independiente enmascarada 8. Resultados percibidos por el paciente (RPP): tiempo transcurrido hasta el empeoramiento al “dolor más intenso” de acuerdo con la escala de valoración numérica (EVN) del dolor más intenso. La EVN es una escala horizontal de un único ítem, de 11 puntos, que completa el paciente, en la que 0 representa “ausencia de dolor”, y 10, “dolor más intenso como pueda imaginarse”. 9. Farmacocinética (FC): concentraciones plasmáticas de LY3484356 en el estado de equilibrio |
