Study information

Scientific title

Neoadjuvant IntraviTreal Ranibizumab treatment in high-risk Ocular melanoma patients: a two-stage single-centre phase II single arm study (NITRO trial)



Study hypothesis

NITRO is a two stage phase II non-randomised single centre trial. The trial will recruit patients who require radical treatment (e-nucleation) due to tumour size. Participants will receive 0.5mg in 0.05ml ranibizumab as an intravitreal injection on day 1 of treatment. Tumour assessment will follow 28 days later and one of the following three decisions will be made.
1. If the tumour shows an increase in size, the patient will stop trial treatment and eye removal will be planned.
2. If the assessment shows a reduction in tumour size that may allow for eye sparing treatment (such as endoresection or radiotherapy), the patient will stop trial treatment and appropriate eye sparing treatment will be planned.
3. If a small response or the tumour size has remained stable, the patient may have a further dose ofRRanibizumab. Up to 6 doses of trial treatment may be given.
All patients will be followed at 6 weeks, 3 months and 6 months following surgery/radiotherapy. Translational samples will be taken at first treatment (day 1) (blood sample, intravitreous fluid sample and tumour biopsy). A second tumour biopsy and intravitreous fluid sample will be taken at final surgery. A second translational blood sample will be taken at the 6 month follow-up.

The primary outcome of the trial is to determine the response rate of intravitreal Ranibizumab in high risk Ocular melanoma patients. The secondary outcomes are to explore relationships between ultrasonographic response, serum and intravitreous VEGF levels.
