Implementing this regimen over a 5-week treatment period, by repeating the injection of 200 μg of anti-CD47-IR700 followed by 100 J/cm2 (on day 1), NIR-PIT treatment further slowed down tumour growth and improved mouse survival in comparison to untreated controls or mice receiving only the anti-CD47-IR700 conjugate. The gene discussed is CD47; the disease is neoplasm.
