The following murine models of cancer are available at Bienta:
– syngeneic tumor growth models: strains C3H and C57Bl/6N;
– xenografts of human tumors in immunodeficient mice: nude, or SCID (severe combined immune deficient).
A standard study design includes 7 days of acclimatization period, 14 days of subcutaneous tumor growth, 7 days of treatment period, and 7 days of post-treatment observation. Tumor size measurements are initiated 9 days post inoculation and monitored three times per week using calipers. Study design includes 3 groups of mice (control, tumor-bearing vehicle treated, and tumor-bearing compound treated group), 10 mice per group.

Tumor treatment procedures include invasive (by IV, IP, SC, and PO routes), noninvasive (with food) routes of drug administration, as well photodynamic therapy (PDT) using a wide range of irradiation wavelengths.

For all experimental groups irradiation was performed 1 hour after Photolon treatment at 14th day after tumor inoculation using the semiconductor laser “Lika-Khirurg M” (Fotonika Plus, Ukraine), and the following parameter settings: l=660 nm, P=250 mW/cm2, light dose = 225 J/cm2. Irradiation regime was controlled by Nova II Laser Power Meter (Ophir Optronics, Israel).
Deliverable: A detailed study report including description of study design, experimental data and interpretation.
Sample Submission: Dry compound or compound in pre-made dosing formulation (amount required depends on the dosing levels and schedules). For example, for treating a group of 8 mice at 10 mg/kg, twice daily (b.i.d.) for 1 week, about 16 mg of the test compound is required.
