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)
Acronym
NITRO
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 of Ranibizumab. 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.

Basic results (scientific)
A total of 7 patients were recruited to the study, with a median age of 66 years. There were 5 males and 2 females . Duration of symptoms was 6 months (mean, range 3-9 months). At baseline, the longest basal diameter was 15.1 mm (mean, range 10-20.4 mm) with a height measured by ultrasonography of 8.6 mm (mean, range 4-12.7mm). Exudative retinal detachment was present in one patient. Visual acuity was 87 letters (ETDRS) (mean, range 104 letters-counting fingers).
No patients achieved complete or partial response at any visit. The study was therefore abandoned and no further patients were recruited. 0/7 patients completed the 6 injections, all withdrew early due to either patient choice or objective progression judged clinically. The last tumour dimensions prior to enucleation were longest basal diameter 15.6 mm (mean, range 12.2-19.9 mm) and height 9.2 mm (mean, range 4.6-12.5).
All patients subsequently underwent enucleation with no complications. Histopathological analysis revealed mixed cell melanoma in 5/7 (71%) and spindle cell morphology in 2/7 (29%) with ciliary body involvement in 4/7 (57%) and the presence of closed loops also in 4/7 (57%). Genetic analysis demonstrated loss of chromosome 3 in 5/7 (71%) but abnormalities in chromosome 1,6 or 8 in all cases.
