Detailed Description
VIBRaNT is a registered phase I trial in patients with locally advanced or metastatic phaeochromocytoma or paraganglioma, not amenable to surgical resection.
Patients will receive vandetanib (an inhibitor of VEGF, EGFR and RET tyrosine kinase) in combination with standard radiation therapy Iodine-131 labelled Meta-iodobenzylguanidine (131I-mIBG).
Vandetanib and 131I-mIBG will be given in 12-weekly cycles: 131I-miBG will be given on day 1 of each cycle and vandetanib will started on day 1 of each cycle and continue to be taken once every day. The phase I trial aims to determine with recommended phase II dose of vandetanib (either 100, 200 or 300 mg once daily) - the dose of vandetanib that patients will receive will depend on the dose under investigation at the time of patient registration.
The vandetanib dose will be determined by the Modified Continual Reassessment Method (mCRM) - a toxicity model which described the probability of a toxicity occurring at each dose level, which is based on clinical judgement and any available toxicity data.

Exclusion Criteria:
- Patients undergoing current treatment with curative intent
- Previous or current malignancies of other histological types within the last 5 years (exceptions listed in the trial protocol)
- Any prior exposure to VEGF, EGFR or RET inhibitors or history of hypersensitivity to vandetanib or any excipient agents
- Evidence of severe or uncontrolled systemic diseases or laboratory finding that in the view of the investigator makes it undesirable for the patient to participate in the trial
- Evidence of active uncontrolled infection (patients on antibiotics are eligible)
- Chronic gastrointestinal disease (e.g. Inflammatory Bowel Disease) or significant bowel resection that would preclude adequate absorption
Cardiovascular exclusion criteria (complete list provided in the trial protocol):
- Significant cardiac event (myocardial infarction), New York Heart Association Class II or above, within 12 weeks before registration, or presence of cardiac disease that in the opinion of the investigator increased the risk of ventricular arrhythmia
- Prior or current cardiomyopathy
- Baseline LVEF < 40% as measured by ECHO/MUGA
- Atrial fibrillation with heart rate >100 bpm
- Unstable ischaemic heart disease (myocardial infarction within 6 months prior to starting treatment, or angina requiring use of nitrates more than once weekly)
- History of arrhythmia that was symptomatic or required treatment
- QTcB prolongation >480 ms at baseline
- QT prolongation with other medications that required discontinuation of that medication
- Any psychiatric or other disorder likely to impact on informed consent or ability to manage isolation
- Major surgery within 28 days prior to registration
- Brain metastases or spinal cord compression, unless treated at least four weeks before the first dose and stable without steroid treatment for 10 days
- Any concomitant medications that may affect QTc, induce or inhibit CYP3A4 function (with the exception of somatostatin or somatostatin analogue) and/or prohibited medications
- Women who are pregnant or lactating

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Occurrence of Dose Limiting Toxicity
Time Frame: From start of cycle 1 to end of cycle 1 (each cycle = 12 weeks)
|
Detailed adverse event monitoring will be conducted according to CTCAE v4.03.
Dose Limiting Toxicity (DLT) is defined as any adverse event or laboratory abnormality detailed in the trial protocol, that is considered to be highly probable or probable trial treatment related and commencing anytime during the DLT evaluation period (from start of cycle 1 to cycle 1 week 12).
Adverse Events include: Haematological, Clinical Chemistry, Cardiovascular, Gastrointestinal, Skin.
|
From start of cycle 1 to end of cycle 1 (each cycle = 12 weeks)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Objective response
Time Frame: Determined using imaging scans performed at baseline (registration), then every 3 months after start of treatment until disease progression up to 3 years from date of registration
|
Response will be assessed according to RECIST v1.1.
Confirmation of complete or partial response is not required.
Stable disease will be considered the best response only is a second assessment has been carried out which confirmed stable disease at least 4 weeks after trial entry.
Assessment will be determined using CT scans and 123I-mIBG scans performed at baseline, then every 3 months after start of treatment until disease progression (up to 3 years from registration)
|
Determined using imaging scans performed at baseline (registration), then every 3 months after start of treatment until disease progression up to 3 years from date of registration
|
Occurrence and Severity of Adverse Events
Time Frame: From date of registration until 30 days after completion of trial treatment (vandetanib and/or 131I-mIBG)
|
Will include all grade 1-5 adverse events.
|
From date of registration until 30 days after completion of trial treatment (vandetanib and/or 131I-mIBG)
|
Progression Free Survival
Time Frame: From date of registration to date of documented disease progression or death from any cause, whichever comes first, assessed up to 3 years from date of registration
|
Progression-free survival will be calculated from the date of trial entry to the date of documented disease progression, or death from any cause.
Where progression is suspected and subsequently confirmed by scans, the date of documented suspected progression will be used.
|
From date of registration to date of documented disease progression or death from any cause, whichever comes first, assessed up to 3 years from date of registration
