A Study of Vemurafenib (RO5185426) in Participants With Metastatic or Unresectable Papillary Thyroid Cancer Positive for the BRAF V600 Mutation

July 22, 2016 updated by: Hoffmann-La Roche

An Open-Label, Multi-Center Phase II Study of the BRAF Inhibitor Vemurafenib in Patients With Metastatic or Unresectable Papillary Thyroid Cancer (PTC) Positive for the BRAF V600 Mutation and Resistant to Radioactive Iodine

This open-label, multi-center study will evaluate the safety and efficacy of Vemurafenib (RO5185426) in participants with metastatic or unresectable papillary thyroid cancer (PTC) positive for the BRAF V600 mutation and resistant to radioactive iodine therapy. Participants will receive vemurafenib 960 milligrams (mg) orally twice daily until progressive disease or unacceptable toxicity occurs.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Best Overall Response Rate in TKI-Naive Participants
Time Frame: Up to approximately 4 years
Best overall response rate was assessed by the investigators according to the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Best overall response rate: the percentage of participants with best objective response of complete response (CR) or partial response (PR) (calculated as the number of participants with best response CR or PR divided by the total number of efficacy-evaluable participants). CR: disappearance of all target lesions with reduction in target/non-target pathological lymph nodes to < 10 millimeters (mm). PR: ≥ 30% decrease in the sum of diameters of target lesions, compared to the baseline sum diameters.
Up to approximately 4 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Best Overall Response Rate in TKI-Experienced Participants
Time Frame: Up to approximately 4 years
Best overall response rate was assessed by the investigators according to RECIST v1.1. Best overall response rate: the percentage of participants with best objective response of CR or PR (calculated as the number of participants with best response CR or PR divided by the total number of efficacy-evaluable participants). CR: disappearance of all target lesions with reduction in target/non-target pathological lymph nodes to < 10 mm. PR: ≥ 30% decrease in the sum of diameters of target lesions, compared to the baseline sum diameters.
Up to approximately 4 years
Clinical Benefit Rate
Time Frame: Up to approximately 4 years
Clinical benefit rate: the percentage of participants with confirmed CR, PR, or stable disease (SD; maintained for at least 6 months) as assessed by investigators according to RECIST v1.1. CR: disappearance of all target lesions with reduction in target/non-target pathological lymph nodes to < 10 mm. PR: ≥ 30% decrease in the sum of diameters of target lesions, compared to the baseline sum diameters. SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, compared to the baseline sum diameters.
Up to approximately 4 years
Duration of Response
Time Frame: From the date of first qualifying response to the date of PD or death for any cause (up to approximately 4 years)
Duration of response (for participants with confirmed best response CR or PR): the interval between earliest qualifying response and date of progression of disease (PD) or death for any cause, whichever occurred first; participants with no documented progression after CR or PR were censored at the date of last known CR or PR, respectively. CR: disappearance of all target lesions with reduction in target/non-target pathological lymph nodes to < 10 mm. PR: ≥ 30% decrease in the sum of diameters of target lesions, compared to the baseline sum diameters. PD: ≥ 20% increase in the sum of diameters of target lesions, compared to the smallest sum on study.
From the date of first qualifying response to the date of PD or death for any cause (up to approximately 4 years)
Progression-Free Survival
Time Frame: From the day of first treatment until the first documented PD or death (up to approximately 4 years)
Progression-free survival: the interval between the day of first treatment and the first documentation of PD or death; participants who were withdrawn from the study without documented progression were censored at the date of the last tumor assessment when the participant was known to be progression-free; participants without post baseline tumor assessments were censored at the time of enrollment. PD: ≥ 20% increase in the sum of diameters of target lesions, compared to the smallest sum on study.
From the day of first treatment until the first documented PD or death (up to approximately 4 years)
Overall Survival
Time Frame: From the date of first treatment to the date of death for any cause (up to approximately 4 years)
Overall survival: the interval between the date of first treatment to the date of death, regardless of the cause of death; participants who were alive at the time of the analysis were censored at the date of the last known alive; participants with no post baseline information were censored at the time of enrollment.
From the date of first treatment to the date of death for any cause (up to approximately 4 years)
Percentage of Participants With Adverse Events
Time Frame: Baseline until 28 days after the last dose of study treatment or until initiation of another anti-cancer therapy, whichever occurred first (up to approximately 4 years)
An adverse event was defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
Baseline until 28 days after the last dose of study treatment or until initiation of another anti-cancer therapy, whichever occurred first (up to approximately 4 years)
Pharmacokinetics of Vemurafenib: Area Under the Concentration-Time Curve (AUC)
Time Frame: Up to approximately 4 years
AUC is a measure of the drug or biologic concentration in the body following administration.
Up to approximately 4 years
