NCT01496313
First received: December 2, 2011
Last updated: July 11, 2014
Last verified: July 2014
  Purpose

The purpose of this study is to give patients with medullary thyroid cancer either 300mg/day or 150mg/day vandetanib and compare how well each dose affects how their cancer responds. It will also help the investigators understand the side effects of different doses in these patients.

Primary Outcome Measures:
  • Change from baseline, overall response rate (ORR) for vandetanib 150 and 300mg with responses determined by the Investigator [ Time Frame: Randomisation to week 60 (maximum) ] [ Designated as safety issue: No ]
    ORR=percentage of patients with a best response of complete or partial response as per Response Evaluation Criteria in Solid Tumors(RECIST)1.1


Secondary Outcome Measures:
  • Frequency and severity of adverse events by treatment arm [ Time Frame: Treatment period + 60 days up to maximum of 24 months ] [ Designated as safety issue: Yes ]
  • Frequency and severity of clinically significant results for blood pressure by treatment arm [ Time Frame: Treatment period + 60 days up to maximum of 24 months ] [ Designated as safety issue: Yes ]
  • Frequency and severity of clinically significant results for QTc prolongation by treatment arm [ Time Frame: Treatment period + 60 days up to maximum of 24 months ] [ Designated as safety issue: Yes ]
  • Frequency and severity of clinically significant results for cardiac ejection fraction by treatment arm [ Time Frame: Treatment period + 60 days up to maximum of 24 months ] [ Designated as safety issue: Yes ]
  • Frequency and severity of clinically significant results for laboratory findings by treatment arm [ Time Frame: Treatment period + 60 days up to maximum of 24 months ] [ Designated as safety issue: Yes ]
  • Frequency and severity ophthalmic abnormalities by treatment arm [ Time Frame: Treatment period + 60 days up to maximum of 24 months ] [ Designated as safety issue: Yes ]
  • Time to objective response (RECIST 1.1) by treatment arm [ Time Frame: Randomization to Week 60 (maximum) ] [ Designated as safety issue: No ]
  • Duration of objective response (RECIST 1.1) by treatment arm [ Time Frame: Randomization to Week 60 (maximum) ] [ Designated as safety issue: No ]
  • Best percentage change in sum of target lesion diameters since baseline (RECIST 1.1) by treatment arm [ Time Frame: Randomization to Week 60 (maximum) ] [ Designated as safety issue: No ]
  • Area under the curve (AUC) of vandetanib in the bloodstream for patients by treatment arm. [ Time Frame: Week 3 to week 60 (maximum) ] [ Designated as safety issue: No ]
  • Maximum concentration of vandetanib in the bloodstream (Cmax) for patients by treatment arm. [ Time Frame: Week 3 to week 60 (maximum) ] [ Designated as safety issue: No ]
  • Area under the curve (AUC) of vandetanib in the bloodstream when QT interval corrected for heart rate according to Fridericia (QTcF) >=500milliseconds by treatment arm [ Time Frame: Treatment period + 60 days up to maximum of 24 months ] [ Designated as safety issue: Yes ]
  • Maximum concentration (Cmax) of vandetanib in the bloodstream when QT interval corrected for heart rate according to Fridericia (QTcF) >=500milliseconds by treatment arm [ Time Frame: Treatment period + 60 days up to maximum of 24 months ] [ Designated as safety issue: Yes ]

Enrollment: 93
Study Start Date: June 2012
Estimated Study Completion Date: March 2015
Primary Completion Date: April 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 300mg vandetanib Drug: 300mg vandetanib

Oral blinded tablets taken once daily.

At objective disease progression or 14 months (whichever is earlier), patient may be unblinded to treatment

Dosing with unblinded study treatment can continue until 24 months after patient was randomised.

At any time dosing may be interrupted for up to 6 weeks due to toxicity. Dosing may restart at a reduced dose (200mg/day). Once reduced, dose increases are not permitted and dosing must stop if further toxicities occur.

Active Comparator: 150mg vandetanib Drug: 150mg vandetanib

Oral blinded tablets taken once daily.

At objective disease progression or 14 months (whichever is earlier), patient may be unblinded to treatment. Patients who have not dose reduced at the time of unblinding may have their dose increased to 300mg

Dosing with unblinded study treatment can continue until 24 months after patient was randomised

At any time dosing may be interrupted for up to 6 weeks due to toxicity. Dosing may restart at a reduced dose (100mg/day) [OR 300 reduced to 200mg/day if dose was increased at unblinding.] Once reduced, dose increases are not permitted and dosing must stop if further toxicities occur.
