High-dose panobinostat (25 mg/kg days 1?, 15 mg/kg remainder, five days per week), ABT-737 (75 mg/kg, 5 days per week) or the mixture of both agents in mice bearing Vk*MYC MM. Normalized M-spike data more than the 18 days of therapy. (b) Survival of mice treated with car (D5W, n ?6), panobinostat (n ?5), ABT-737 (n ?five) or the mixture of both agents (n ?six). (c) Mice bearing Vk*MYC MM were then treated with lower doses of each agents as follows: automobile (n ?5); panobinostat (five mg/kg, five days per week, n ?5); ABT-737 (50 mg/kg, two times each day, n ?5); or the combination of both agents (n ?6), for four weeks. Final results are depicted as normalized M-spike over the 26 days of remedy, and (d) survival of mice treated together with the reduce doses of both agents, alone and in mixture. *Po0.05 versus vehicleCell Death and DiseasePreclinical drug screening using Vk*MYC myeloma GM Matthews et alVehicle Panobinostat (10mg/kg) MD5-1 (50g/mouse) 250 200 150 100 50 0 1 5 12 19 Day of therapy Car Panobinostat (7.5mg/kg) MD5-1(50g/mouse) Panobinostat + MD5-1 % survival 26 * * Panobinostat + MD5-1 % survivel one hundred 80 60 40 20 0 0 10 20 30 40 Day of therapy Automobile Panobinostat (10mg/kg) MD5-1 (50g/mouse) Panobinostat + MD5-Normalized M-spike ( of d0)Normalized M-spike ( of d0)one hundred 80 60 40 20Vehicle Panobinostat (7.5mg/kg) MD5-1 (50g/mouse) Panobinostat + MD5-**0 -4 five 19 12 Day of therapyDay of therapy Automobile Panobinostat (10mg/kg) 5-AZA (5mg/kg) Panobinostat + 5-AZA Percent survival Vehicle Panobinostat (10mg/kg) 5-AZA (5mg/kg) Panobinostat + 5-AZANormalized M-spike ( of d0)one hundred % survival 80 60 40 20 0 0Vehicle Panobinostat (7.5mg/kg) MD5-1 (50g/mouse) Panobinostat + MD5-500 400 300 200 100* # 12 19* #0 33 40 Day of therapy40 60 Day of therapyPre- 5 treatment40 60 Day of therapyFigure 7 In vivo treatment consisting of panobinostat in combination with MD5-1 just isn’t well tolerated and does not improve survival of C57BL/6 mice bearing Vk*MYC MM more than single-agent panobinostat remedy alone, whereas its combination with 5-AZA gives considerable benefit.
