Specific laboratory values at Screening including: Hemoglobin \< 8.0 g/dL, WBC \< 3,000 cells per microliter, platelet count \<75,000/mm3, Creatinine \> 2.0 mg/dL; AST and/or ALT \> 3 times the upper limit of normal or any other clinically significant lab abnormality which in the opinion of the investigator should be exclusionary;
• •13. Proliferative retinopathy within 5 years of signing consent or any ophthalmological condition which, in the opinion of the investigator, should be exclusionary; any condition that precludes standard ophthalmologic examination;
