O que o estudo está medindo?

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Best Overall Response
Prazo: From randomization to treatment discontinuation for any reason, average 6 months

Percentage of patients whose Best Overall Response (BOR) is assessed as Complete Response (CR) or Partial Response (PR). Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by CT or MRI: CR: disappearance of all target lesions; PR: >=30% decrease in the sum of the longest diameter of target lesions.
From randomization to treatment discontinuation for any reason, average 6 months

Medidas de resultados secundários

Medida de resultado
Descrição da medida
Prazo
Progression Free Survival
Prazo: From randomization to first documented objective PD or death if PD does not occur, average 6 months

Time from randomization until the date of objective PD or the date of death (by any cause in the absence of disease progression). Progression of diseases is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
From randomization to first documented objective PD or death if PD does not occur, average 6 months
Duration of Response
Prazo: From first confirmed CR or PR to confirmed PD, average 6 months

Time from the CT or MRI that first confirmed complete (CR) or partial response PR) to the CT or MRI that first confirmed progression of disease progression (PD). Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by CT or MRI: CR: disappearance of all target lesions; PR: >=30% decrease in the sum of the longest diameter of target lesions; PD = 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
From first confirmed CR or PR to confirmed PD, average 6 months
Overall Survival
Prazo: From randomization to death from any cause, average 12 months

Time from randomization until the date of death by any cause. Patients who are still alive at the time of the analysis, or who have become lost to follow-up or withdrawn consent will be censored at their last date known to be alive
From randomization to death from any cause, average 12 months
Disease Control Rate
Prazo: From randomization to treatment discontinuation for any reason, average 6 months

Percentage of all treated patients whose best overall response was complete response (CR), partial response (PR), or stable disease (SD) for a minimum of 6 weeks. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by CT or MRI: CR: disappearance of all target lesions; PR: >=30% decrease in the sum of the longest diameter of target lesions; SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease.
From randomization to treatment discontinuation for any reason, average 6 months
Incidence of Treatment Emergent Adverse Events (TEAEs) and changes in clinical abnormalities
Prazo: From the first dose of either study drug to 30 days after the last dose of study treatment, average 7 months

TEAE is defined by occurrence of an adverse event that started or worsened in severity on or after the first dose of CTX-009 or paclitaxel through 30 days after the last dose of CTX-009 or paclitaxel. Change in clinical abnormalities is defined as an increase in abnormality grade in a laboratory result, vital sign, or ECG parameter from predose result to worst postdose result (graded according to the Common Terminology Criteria for Adverse Events v5.0 for all analytes except for brain natriuretic peptide and troponin subtypes, which are interpreted in reference to the laboratory reference range for each), a post-baseline potentially clinically significant vital sign abnormality, or a post-baseline potentially clinically significant ECG abnormality.
From the first dose of either study drug to 30 days after the last dose of study treatment, average 7 months
Efficacy of CTX-009 in combination with paclitaxel in patients who crossed over from the paclitaxel only arm
Prazo: From the first dose of CTX-009 following crossover to the subsequent radiographic progression confirmed by the ICR or death, whichever occurs first

Evaluation of ORR, DCR and progression free survival 2 (PFS2) in the crossover set (COS). PFS2 is defined as the time from the first dose of CTX-009 following crossover to the subsequent radiographic progression confirmed by the ICR or death, whichever occurs first
From the first dose of CTX-009 following crossover to the subsequent radiographic progression confirmed by the ICR or death, whichever occurs first
Quality of Life (QoL)
Prazo: From randomization to treatment discontinuation for any reason, average 6 months

Changes in QoL scores, as measured using the EORTC QLQ-C30 and BIL21, from baseline in patients treated with CTX-009 in combination with paclitaxel vs. paclitaxel alone
From randomization to treatment discontinuation for any reason, average 6 months
