Summary
Brief summary (as posted)
The purpose of this study is to evaluate the potential of \[18F\]-ML-10 to serve as a non-invasive imaging tool for the early detection of apoptosis in brain metastases in response to radiation therapy, in patients subjected to stereotactic radiosurgery (SRS). Such early detection may improve clinical management of patients with brain metastases, as it may help early identification of non-responders, and subsequently potentially lead to optimization of radiation techniques such as the need for whole brain radiation therapy (WBRT), addition of brain penetrating chemotherapy or an early decision on referral of the patient with non-responsive lesions to surgery or to systemic chemotherapy. The experimental design of the present study aims to evaluate the potential of non-invasive PET examination with \[18F\]-ML-10, to provide the clinician with an assessment of response early in the course of treatment, via non-invasive molecular imaging of radiation-induced apoptosis. This information on tumor responsiveness is currently available only several weeks to months after completion of radiotherapy.

Inclusion Criteria: The Patient may only be included in the study if ALL of the following statements are fulfilled: 1. Male or female patient diagnosed with metastatic non hematological cancer, with up to 4 brain metastases of which at least one has a minimal diameter of 1.5cm , as assessed by MRI (utilized for SRS planning) and is scheduled for SRS. These metastases will be defined as target lesions. 2. Patient is ≥ 18 years of age at the time of signature of the informed consent form. 3. Fully conscious patient who has been given written and verbal information, and has then provided an informed consent. 4. Patient who is able to cooperate with the studies requirements to lie still during PET/CT imaging scans, which may last for up to 3 hours. 5. ECOG performance status of 0, 1 or 2 at the time of enrollment. 6. Patient with life expectancy ≥ 12 weeks. 7. Adequate renal function and adequate hepatic function as assessed by standard laboratory criteria and defined as: 1. Creatinine clearance ≥ 60 ml/min/1.73m2according to Cockroft \& Gault Formula 2. Total bilirubin ≤ 1.5 times the ULN 3. Aspargine aminotransferase (AST), alanine aminotransferase (ALT) ≤ 3 times the ULN in patients without liver metastases; ≤ 5 times the ULN in patients with liver metastases 8. Serum calcium levels, adjusted to albumin level, within normal limits. 9. For a female patient, pregnancy or breast-feeding are restricted. Woman of child bearing potential must have a negative serum pregnancy test at screening. Exclusion Criteria: If any apply, the patient must not be included in the study: 1. Unstable medical condition, such as severe ischemic heart disease, liver disease or pulmonary disease, which may risk the patient during the study, as judged by the investigator. 2. Any indication of imminent brain herniation 3. Any known psychiatric disorder other than mild depression or anxiety. 4. Known allergy to Gadolinium 5. Other condition that might jeopardize the safety of the patient or the evaluation of the study results, as judged by the investigator. 6. Treatment with any non-marketed investigational drug within 30 days prior to administration of \[18F\]-ML-10 7. Patient who received Whole Brain Radiation Therapy (WBRT) within 6 months prior screening and/or planned to receive WBRT 8 weeks post SRS 8. Patient receiving concurrent treatment with temozolamide or planned to receive temozolamide within 8 weeks post SRS 9. Woman of child-bearing potential who is not using an adequate and medically acceptable contraceptive method. Men who do not agree to use effective contraception during the study and for a period of 60 days following the last administration of \[18F\]-ML-10.
