Ejemplo 3: Cambio en el peso corporal después de una sola administración.
10 Método. Ratas Sprague Dawley magras se mantuvieron con una dieta baja en grasa durante el estudio. El peso corporal medio fue 319 gramos al comienzo del estudio. Los animales se dividieron en seis grupos (n=6/grupo). Cada grupo fue asignado para recibir uno de los siguientes: vehículo; Comp. 1 a 2,6 mg/kg en vehículo; Comp. 2 a 2,7 mg/kg en vehículo; Comp. 4 a 2,7 mg/kg en vehículo; Comp. 2 a 10 mg/kg en vehículo. Cada animal de ensayo
15 recibió una única inyección subcutánea a tiempo=0. La ingesta de alimento y el cambio en el peso corporal (corregido para el % de vehículo) se controlaron durante 14 días, y los resultados se registraron como se muestra (Figuras 1A a 1B). Compuestos administrados: Vehículo (en recuadro); Comp. 1 a 2,6 mg/kg (triángulo con la punta hacia arriba); Comp. 2 a 2,7 mg/kg (triángulo con la punta hacia abajo); Comp. 4 a 2,7 mg/kg (rombo); Comp. C2 a 10 mg/kg (círculo).
20 Resultados. Tal como se representa gráficamente en las Figuras 1A a 1B, la administración de cada polipéptido diseñado por ingeniería genética dio como resultado una reducción de la ingesta de alimento y peso corporal. Todos los compuestos se proporcionaron en una dosis equimolar por peso de compuesto; todos los compuestos se proporcionaron a 120 nmol/kg (es decir, Comp. 1 a 2,6 mg/kg; Comp. 2 y Comp. 4 a 2,7 mg/kg; Comp. C2 a 10
25 mg/kg). Se debe indicar que el Comp. C2 (es decir, A200) es un dímero de dos restos, comprendiendo cada resto la región FC de IgG1 fusionada a leptina humana. El Comp. 1 y el Comp. 2 tienen una actividad similar al Comp. C2 que, por ser un dímero, tiene realmente dos leptinas por molécula. Aunque la eficacia (disminución del peso corporal) parece similar, es evidente que la tendencia favorece ambos polipéptidos diseñados por ingeniería genética con respecto al Comp. C2. Cuando se mira en una base molar de leptina, los polipéptidos diseñados
30 mediante ingeniería genética son superiores para la inhibición tanto de la ingesta de alimento como del peso corporal, ya que el Comp. C2 tiene 2 moles de leptina en cada complejo Fc-leptina dimérico, mientras que cada mol de ABD-resto de leptina tiene solamente 1 mol de leptina.
Resultados anteriores han demostrado que se necesitan aproximadamente 500 ug/kg/día de un compuesto A500
35 para conseguir una pérdida de peso de 9-10 % a los 7 días cuando se administra mediante infusión continua a una rata magra. Esto da como resultado 2,5 mg de compuesto de leptina A500 a los 5 días y de 3,5 mg de compuesto a los 7 días. Puesto que el propio compuesto A500 tiene 16067,68 g/mol y el peso molecular del Comp. 2 es ∼22.510 g/mol, se anticiparía la necesidad de 1,4X más veces proteína de fusión ABD durante los 5 días. En su lugar, solamente se administró 1,08x (2,7 mg/2,5 mg) más compuesto, lo que indica una sorprendente propiedad que
40 ahorra dosis.

Ejemplo 20: Estabilidad de los polipéptidos diseñados mediante ingeniería genética
Tal como se establece en la Tabla 9 siguiente, los polipéptidos diseñados mediante ingeniería genética descritos en

Como se muestra en la Tabla 9, los polipéptidos quiméricos tienen buena potencia (Tabla 9A) y pureza (Tabla 9B) después de dos semanas a 40°C, como se determina mediante cromatografía líquida de alto rendimiento (HPLC) en fase invertida.

Tal como se establece en la Tabla 10 siguiente, los polipéptidos diseñados mediante ingeniería genética descritos en el presente documento son químicamente estables. El Compuesto 15 se formuló a tres concentraciones diferentes en el siguiente tampón: ácido glutámico 10 mM, glicina al 2 %, sacarosa al 1 %, Tween 20 al 0,01 %, pH 4,25 y se
20 almacenó a 5°C, 15°C, o 25°C. Como se muestra en la Tabla 10, el Compuesto 15 es químicamente estable a 10, 20, y 30 mg/ml durante al menos 1 mes a 5-25°C, según se determina mediante HPLC.
