Best Overall Response (BOR) Assessed by an Independent Review Committee Using Response Evaluation Criteria In Solid Tumors (RECIST 1.1)
Query!
Assessment method [1]
0
0
BOR was defined as a complete response (CR) or partial response (PR) confirmed per Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1. Patients who never received study treatment and treated patients without any post-baseline tumor assessments were considered as non-responders. CR: Disappearance of all target lesions, all non-target lesions, and no new lesion. Any pathological lymph nodes must have had reduction in the short axis to <10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, no progression in non-target lesion, and no new lesion.

Duration of Response Assessed by an Independent Review Committee Using Response Evaluation Criteria In Solid Tumors (RECIST 1.1)

Assessment method [2]
0
0
Duration of response was defined as the time interval between the date of the earliest qualifying response and the date of disease progression (PD) or death, only for those patients whose best overall response was complete response or partial response. PD: At least 20% increase in the sum of diameters of target lesions compared to Nadir (smallest sum of diameters on-study), unequivocal progression of existing non-target lesions, or presence of new lesion. For patients who were alive without progression, duration of response was censored on the date of the last evaluable tumor assessment.

PFS was defined the time interval between the date of the first treatment and the date of progression or death from any cause, whichever occurred first. Deaths that occurred in patients without disease progression were considered to be a PFS event on the date of death. Patients who neither progressed nor died were censored on the date of the last evaluable tumor assessment prior to the data cutoff date.

Improvement in Physical Symptoms (Improvement in Physician's Assessment of Global Performance Status and Oxygen Saturation Requirements, and Decrease in Total Dose and Frequency of Narcotic Pain Analgesics) During Treatment in Comparison to Baseline
Query!
Assessment method [6]
0
0
Three parameters were measured. (1) Improvement in the Physician's Assessment of Global Performance status on a 7-point scale (1=very much better to 7=very much worse). (2) Improvement in oxygen saturation requirements, defined as a clinically meaningful increase in oxygen saturation requirement (from a baseline value < 95% to = 95% saturation using a pulse oximeter). (3) A decrease in total dose and frequency of narcotic pain analgesics. The percentage of patients showing improvement (1 and 2) or a decrease (3) are reported.

Three electrocardiograms (ECG) were obtained pre-dose and 2, 4, 6, and 8 hours post-dose at Days 1 and 15 of Cycle 1 and again pre-dose and 4 hours post-dose at various Cycles throughout treatment. Five baseline triplicate ECGs were obtained before the start of treatment at the same time points used during treatment. Reported is the largest mean time-matched QTcP change from baseline. QTcP=QT/(60/heart rate)^ß (ß=mean [calculated separately for males and females] log-transformed QT versus log-transformed RR regression slopes using all available pre-treatment (baseline) ECG values.

Summary
Brief summary
This open-label single arm study will assess the efficacy, safety and tolerability of
Vemurafenib in previously treated patients with metastatic melanoma. Patients will receive
oral Vemurafenib [RG7204; PLEXXIKON: PLX4032] at a dose of 960 mg b.i.d. continuously until
disease progression or withdrawal from study and will be assessed at regular intervals for
tumour response and tolerability. Target sample size is <100 patients.
