SAMPLE SIZE:
The sample size of up to 30 patients was selected based on previous disease-stratifying 89Zr-labelled antibody studies in:
- breast cancer (n=23, anti-VEGFA antibody
- colorectal cancer (n=7; anti-EGFR antibody
- head and neck cancer (n=20; anti-CD44v6 antibody
- pancreatic and ovarian cancer (n=11; anti-mesothelin antibody

DATA ANALYSIS
1. The suitability of hu/mo-10D7 for subsequent use as a theranostic will be assessed for PET scans by measurement of uptake in tumours compared with uptake in normal tissues, using both semi-quantitative measures (SUVmax ratios) as well as formal organ and tumour dosimetry estimates from multi time point imaging.

2. 89Zr-hu/mo-10D7 parameters will also be determined from whole blood concentration-time data measured by scintillation counting and mass spectrometry are: Maximum Observed Plasma Concentration (Cmax); Terminal Phase Half-life (t1/2); Mean Residence Time (MRT); Elimination Rate Constant (Lambda-z); and Clearance rate. Mean Tumour and Organ Dose and Effective Dose of 89Zr-hu/mo-10D7 in tumours and organs, as a fraction of total MBq dose will be determined from PET-CT scans for all participants.

3. Safety will be assessed based on collated data for the cohort of:
i) Adverse events (AE) and serious adverse events (SAE) relating to liver, kidney, cardio-vascular, immunological and haematological toxicities including:
ii) Clinical Chemistry Data - glucose, creatinine, phosphorous, magnesium, calcium, carbon dioxide content, albumin, potassium and sodium.
ii) Haematology Data - haemoglobin, lymphocytes, haematocrit, neutrophil count, platelet count and white blood cell count.
iv) ECG- to review significant changes from baseline to post administration.
v) Vital signs (including pulse rate, blood pressure, temperature, respiratory rate).

Summary
Brief summary
This study aims to evaluate the safety, biodistribution and pharmacokinetics of 89Zr-hu/mo-10D7 to detect known tumour deposits in patients with advanced epithelial Ovarian Cancer.
Who is it for?
You may be eligible for this study if you are an adult with recurrent, histologically proven advanced ovarian cancer with a macroscopically visible tumour on diagnostic imaging.
Study Details
All participants who meet the eligibility criteria in this study will receive a single dose of 89Zr-hu/mo-10D7 as an intravenous infusion over 30 minutes to delivery maximum dose of 4.5 mg protein and 37 MBq radiation.

During and after completion of the treatment participants will be assessed for safety, biodistribution and pharmacokinetics of 89Zr-hu/mo-10D7 via vital signs, blood tests, ECG, urinalysis and PET/CT scan.

It is hoped that this research project will demonstrate hu/mo-10D7 targets advanced ovarian cancer metastases in humans and therefore prove its potential utility as a theranostic in ovarian cancer.
